1.1. INTRODUCTION: THINKING
Most of our waking hours, and even when we are asleep and
dreaming, we are thinking. It is hard not to think. As you read these
words you are thinking, and even if you stop thinking about whatmunotes.in

you are reading, your thoughts wander off to something else -
perhaps to what you are going to do tomorrow -you will still be
thinking. What do we do when we think? Loosely speaking, we
might say that we mentally, or cognitively, process information.
There are different definitions of thinking. We would discuss in
briefly.
Thinking consists of the cognitive rearrangement and
manipulation of both information from the environment and the
symbols stored in long -term memory. From another viewpoint,
thinking is the form of information processing that goes on during
the period between a stimulus event and the response to it.
In other words, thinking is the set of cognitive processes that
mediate, or go between, stimuli and responses. To illustrate,
suppose you are trying to make a decision about buying a new
mobile. The seller presents several mobiles in your price range (the
stimu li), and you eventually purchase one of them (the response).
Before making the response, however, you consider the
advantages and the disadvantages of the several mobiles; you
process the information you have about them. Your thinking about
the mobiles -thus mediates between the mobiles as stimuli and
your eventual response of buying one of them.
The general definition of thinking given above encompasses
many different varieties of thought. For instance, some thinking is
highly private and may use symbols with very personal meanings.
This kind of thinking is called as autistic thinking; dreams are an
example of autistic thinking. Other thinking is aimed at solving
problems or creating something new; this is called directed thinking.
Directed thinking is th e kind you were engaged in when you solved
(or tried to solve) the problem.
1.1.1.How people think?
One of the most complex and highest forms of human
behaviour is thinking. The topic of thinking came within the purview
of psychology only in the 1960s with the growth of cognitive
psychology. Behaviorists were not in favour of the study of thinking
as according to them thinking was covert in nature and not
empirically observable. Thinking is closely related to learning,
memory, intelligence, decision mak ing and language development.
We would discuss these topics in this as well as the next unit.
1.1.2.Thinking or Cognition:
The terms thinking and cognition are often used
synonymously. There is considerable difference between them. The
term cognition is much broader in scope as compared to thinking.
According to one definition, thinking is a symbolic mediation or a
symbolic bridge that fills the gaps between a situation and themunotes.in

response we make to it. According to Watson, ‘thinking’ is ‘sub -
vocal speech’ . Thinking is also defined as “mental activity that goes
on in the brain when a person is processing information such as
organizing it, understanding it, and communicating it to others.”
Thinking is not only verbal in nature but also involves the use of
mental images or mental representation. The three most important
elements involved in thinking are mental images (also called as
mental imagery), concepts and prototypes.
1.2CONCEPTS
Concepts are an important class of language symbols used
in thinking. A concept is a symbolic construction representing some
common and general features of object or events. Some natural, or
basic, concepts are easily acquired and appear in thinking early in
life. Other concepts are acquired by discriminative learning by
seein g examples of the concept in different context, and by
definition. There are different types of concepts. W e would discuss
these in detail.
1)Superordinate Concept:
It is the most general type of a concept, such as “bird” or
“vegetable” or “fruit”.
2)Basic level Type:
A basic level type of concept is one around which other
similar concepts are organised, such as Mango or apple or
watermelon, as there can be many different types of mangos such
as alphonso, dusseri, badami, payri, langda, etc.
3)Subordina te Concept:
It is the most specific type of a concept. Such as “Crackle
Cadbury chocolate” or the name of your dog or a “Kashmiri apple”,
etc.
4)Formal Concept:
Formal concepts refer to those concepts which have a strict
definition. These concepts are defined by specific rules or features
and are very rigid. Formal concepts are generally taught in schools
and colleges as a part of academic activity.
5)Natural Concept:
Natural concepts are those concepts which people form as a
result of their experien ces in the real world. Unlike formal concepts,
natural concepts are not well defined. Is tomato a vegetable of
fruit? Is duck a mammal or a bird? What about whale, is it a fish or
a mammal? We form concepts about these as a result of ourmunotes.in

Page 4

experiences in the outside world. Natural concepts help us to
understand our surrounding in a less structured and rigid manner.
Becoming a human being involves the attainment of
concepts: much human thinking uses them. It is therefore of some
practical value to discovery w hat helps or hinders concept
attainment. One factor in concept attainment is transfer. A second
factor is the degree to which the common elements are isolated,
grouped, or otherwise made conspicuous. This may be called as
distinctiveness. A third factor is ability to manipulate the materials
involved in the concept. Rearranged, rewarding, or reorganized
materials containing the common properties helps people to
discover the concept. Another factor is the instructional set people
have. Finally, people usuall y learn concept faster if they have all the
relevant information available at the same time, instead of being
given only a piece of information at a time.
1.2.1. Mental Imagery:
Mental imagery is also called as visual imagery or imagery
and is an importan t component of human thought or cognition.
Mental imagery refers to the representations that stand for objects
or events and have a picture -like quality. Mental imagery is used by
most people in their everyday life. Considerable degree of research
on menta l imagery has been done by Allan Paivio, Kosslyn and
others.
Research studies by Kosslyn and his colleagues (1990)have
shown that most of our imagery is visual. They did some pioneering
studies on mental rotation of visual images. Kosslyn also found that
when we form a mental image our experience seems much like
seeing something in our mind. It seems a lot like vision. When we
form a mental image we seem to be able to manipulate them and
we seem to be solving problems some times by means of
manipulating th em. Mental images can be quite detailed but they
tend to be less detailed than actual perception. Kosslyn's research
has demonstrated the following with respect to imagery and size.
People take longer to make judgements about the
characteristics of small mental images than of the large mental
images.
It takes longer time to travel a large mental distance than when
images are different.
Research shows that visual imagery is a powerful strategyfor
enhancing memory. Research has also shown that memory is mo st
effective when the items must be recalled are shown interacting
with each other (Begg 1982).munotes.in

1.2.2. Prototypes:
Prototype is another important element of thinking. It can be
defined as an example of a concept that closely matches the
defining characte ristics of a concept. Prototypes can be defined as
mental models of the typical qualities of members of some group or
category. Concepts simplify our thinking. We can’t think of life
without concepts. Without concepts, we would need a different
name for ev ery person, vents, objects and ideas. For example,
suppose we ask a child to “throw a ball”, a child will not understand
if he has no concept of ball or throw. So we can say that concepts
such as ball gives us much information with little cognitive efforts .
Prototypes can be defined as mental frame -work for e.g.,
we have prototypes for Indian political leaders, certain film stars,
criminals, etc. Prototypes describe the truly typical member of such
categories. The prototypical model helps us to compare new
persons we meet in order to determine if they do or do not fit into
the category. When they fit quite well, we can readily place them in
various categories. When they do not, the situation is more
puzzling. For example, suppose you meet a young woman w ho told
you that she reads books as a hobby, likes to do social work and
who was dressed in simple clothes. When you discovered that she
was a film actress you would probably be surprised. The reason is
simple: she does not seem to fit well with the protot ype of film
actress that you have built up through past experience. Prototypes
also exert important effects on social thought and social behaviour.
The prototype for objects and events varies from culture to culture
and from region to region. For e.g., In an Indian family it is
customary to touch the feet of elders. However, such a custom
does not exist in many other cultures. Similarly, prototype of fruits
or drink varies from region to region depending upon what fruit or
drink is commonly available in a g iven region or culture. For e.g.,
someone who lives in a tropical area will have a different prototype
for fruit as compared to one who stays in Northern Hemisphere. For
e.g., someone who grew up in an area where there are many
coconut trees, for e.g., Ker ala might think of coconut as the most
typical fruit as compared to a person who comes from Kashmir
where apples are found in plenty. It has also been noted that
people who are familiar or have knowledge about given objects and
events will have a different prototype about these objects and
events as compared to persons who are not knowledgeable or lack
information about such objects and events. Thus, many factors
influence the development and formation of prototypes. Some
common factors are as follows:
Geographical Region
Culture
Information and Knowledge
Experiencemunotes.in

Page 6

One’s thinking is considerably influenced by the prototype
thatone develops or holds. They also aid in the process of problem
solving and decision making. Eleanor Rosch (1973) has done
conside rable research work with respect to prototypes. The
prototype approach has had an important impact on cognitive
psychology and other related disciplines.
1.3 PROBLEM SOLVING STRATEGIES AND
OBSTACLES
In general, a problem can be any conflict or difference
between one situation and another situation we wish to produce our
goal. In trying to reach the goal of problem solution, we use
information available to us from long term memory and from ou r
here -and-now perception of the problem situation before we
process this information according to rules that tells us what we can
and cannot do. In other words, many instances of problem solving
can be considered a form of rule -guided, motivated information
processing (Newell & Simon, 1972).
1.3.1. Problem Solving Str ategies:
Many of the rules used in solving problems concern the
changes that are permissible in going from one situation to another.
Four major types of such rules are algorithm, heuristics, trial and
error and insight.
1)Algorithm:
An algorithm is a set of rules which, if followed correctly, will
guarantee a solution to a problem. For instance, if you are given
two numbers to multiply, you immediately start thinking of all the
rules for multiplication you have learned and you apply these
algorithm to the problem. If you follow the rules correctly, you will
solve the problem. Algorithm is a step -by-step procedure that
guarantees a solution. But it can be laborious and frustrating
experience.
2)Heuristics:
Heuristic are simpler thinking strategies, usually based on
our past experience with problems, that are likely to lead to a
solution but do not guarantee success. One common strategy, or
heuristic, is to break the problem down into smaller sub problems,
each a little closer to the end goal.
3)Trial and Err or:
This is the most commonly used method in problem solving.
It is used when a person does not have any well thought out
strategy for solving a problem or when he is incapable of thinking
about his problem systematically. In other words, he does not kn ow
about the rules to help him solve the problem. He goes on tryingmunotes.in

Page 7

7
one thing after another till somehow the problem gets solved by
chance –an abrupt, true seeming and often satisfying solution.
Insight strikes suddenly with no prior sense of ‘getting war mer’ or
feeling close to a solution.
Mechanical solutions also involve solving by rote or a
learned set of rules. Many problems in life can be solved by merely
applying certain rules mechanically. If the rules are applied
correctly the solution is sure to be found. Many problems in
everyday life and in school and college situations involve
mechanical application of the facts or knowledge that we have
acquired. The strategy involving use of algorithms and heuristics is
representatives of this method.
4)Insig ht:
This is another important method of solving a problem. For
some problems, solutions occur suddenly. Insight occurs when the
problem solver suddenly ‘sees’ the relations involved in a task and
is immediately able to solve the problem. It was Kohler who first
suggested that learning takes place by insight. An instance of
insight is found in the example of Archimedes who ran naked out of
his bathtub, shouting ‘Eureka’, when he found an answer to a
problem that had troubled him for a long time. Most cre ative
problems are solved through insight. When human beings solve the
problem through insight they experience a good feeling called as
‘aha’ experience. Thus, insight occurs when the learner ‘suddenly
sees’ the solution involved in a task and is immediate ly able to
solve the problem. When he suddenly gets the solution, he is said
to have got insight.
1.3.2. Obstacles in Problem Solving:
Problem solving is not an easy task, it is filled with
considerable difficulties or obstacles that are involved in the
process of problem solving. Some problems are difficult to solve as
compared to others. Human beings commit errors or have
limitations that come in the way of solving problems. The three
most common barriers to solving a problem are as follows:
1. Functio nal Fixedness
2. Mental Set
3. Confirmation bias.
4.Using incomplete or incorrect representations
5. Lack of Problem specific knowledge or expertise
We will discuss each of these briefly.
1.Functional Fixedness:
Functional Fixedness means that the functions or uses we
assign to objects tend to remain fixed or stable. Functional
fixedness is a cognitive bias that that limits a person to using anmunotes.in

Page 8

8
object only in the way it is traditionally used. Karl Duncker defined
functional fixedness as being a "mental block against using an
object in a new way that is required to solve a problem." This
"block" then limits that ability of an individual to use the components
given to them to make a specific item, as they cannot move past
the original intention of the obje ct. When people develop functional
fixedness, they recognize tools only for their obvious function. For
example, an object is regarded as having only one fixed function.
The problem -solver cannot alter his or he rmental set to see that
the tool may have mu ltiple uses. To overcome functional fixedness,
we need to think flexibly about other ways that objects can be used.
To overcome functional fixedness, we have to realize that an object
designed for one particular function can also serve another
function. Th e history of technology offers numerous examples of
overcoming functional fixedness. For instance, the steam engine
was used for a century to pump water out of mines before an
inventor realized that it could be used as a source of locomotive
power (Gellatl y, 1986).
2.Mental Set:
Mental set is a tendency to adopt a certain framework,
strategy or procedure or more generally, to see things incertain
ways instead of others. Mental set is analogous to perceptual set,
the tendency to perceive an object or patt ern in a certain way on
the basis of your immediate perceptual experience. Mental set is
one type of functional fixedness. Mental set directs the thinking
process to solving problems in the same way. When problem
solvers have mental set, they keep trying t he same solution they
have used in previous problems, even though the problem could be
approached via other, easier ways. Mental sets involve a kind of
mindless rigidity that blocks effective problem solving (Langer,
1989).A mental set often works against us in our everyday
experiences too. A number of research studies have been carried
out to study how mental set effects problem -solving behavior. The
three major studies using different problems are as follows:
i)Luchin’s study using water Jar problem. ii)Nine -dot problem iii)
Six match stick problem. Luchin (1942) in one of the earliest studies
on mental set demonstrated that 75 percent of the students were
blind to easy solution and continued to solve the problem in the
same fashion as they did in the pra ctice problem.
3.Confirmation bias:
Confirmation bias is one of the barriers to logical thinking.
Confirmation bias refers to a type of selective thinking whereby one
tends to notice and to look for what confirms one's beliefs, and to
ignore, not look fo r, or undervalue the relevance of what contradicts
one's beliefs. Confirmation bias is a phenomenon wherein decision
makers have been shown to actively seek out and assign more
weight to evidence that confirms their hypothesis, and ignore ormunotes.in

Page 9

under weigh ev idence that could disconfirm their hypothesis.
Confirmation bias is one of the hurdles in objective evaluation of a
theory. In this a researcher overemphasizes data supporting the
theories they favour and tend to ignore or downplay data which are
inconsist ent with their views.
4.Using incomplete or incorrect representations:
Irrelevant information hinders problem solving as it slows the
process down, can cause confusion or misunderstandings.
5.Lack of Problem Specific Knowledge or Expertise:
If we don't have problem specific knowledge or expertise, we
can’t solve problem. Even if we are going to solve problem it can
create difficulties in solving problem.
1.4 FORMING GOOD AND BAD DECISIONS AND
JUDGMENTS
Decision -making is a kind of problem solving in whi ch a
person must choose among several alternatives. In choosing
among alternatives that involve certain amounts of risk, we are
often guided by heuristic rules. There are two types of heuristics.
1)Availability Heuristics
2)Representative Heuristics
We would discuss each of these heuristics briefly.
1)Availability Heuristics:
Availability heuristics is a mental shortcut that helps us make
a decision based on how easy it is to bring something to mind. In
other words, we often rely on how easy it is to think of examples
when making a decision or judgment. For instance, in 2011, what
percentage of crimes do you suppose involved violence? Most
people are likely to guess a high percentage because of all the
violent crimes -murder, rape, robbery, and assault -thata r e
highlighted on the news. Yet the FBI reported that violent crimes
made up less than 12% of all crimes in the United States in 2011.
So, anything that makes information ‘pop up’ into mind -its
vividness, recency or distinctiveness can make it seem com mon
place. We often fear the wrong things. For example, we fear flying
because we play in our head some air disaster.
2)Representative Heuristics :
A mental shortcut that helps us make a decision by
comparing information to our mental prototypes. For exam ple, if
someone was to describe an older woman as warm and caring with
a great love of children, most of us would assume that the older
woman is a grandmother. She fits our mental representation of a
grandmother, so we automatically classify her into that category.munotes.in

Page 10

10
These rules include judging on the basis of representativeness,
using the available information to decide which outcome is more
likely, and using adjustment to arrive at an estimate of the
probability of a certain outcome. Each of these heuristic s introduces
bias into the decision -making process.
Heuristics are simple decision -making rules we often use to
make inferences or draw conclusions quickly and easily. Heuristics
are strategies, usually based on our past experiences with
problems, that are likely to lead to a solution but do not guarantee
success. We make use of many mental heuristics in our effort to
think about and use social information. Two most important
heuristics approaches in solving a problem are as follows:
1)The Means -Ends A nalysis
2) The Analogy Approach.
1)The Means -Ends Analysis:
It is a problem solving strategy in which the solver compares
the goal to the current state, and then chooses a step to reduce
maximally the difference between them. In other words this strategy
involves figuring out the “ends” you want and then figuring out the
“means” you will use to reach those ends. The means -ends
analysis concentrates the problem solver’s attention on the
difference between the current problem state and the goal state.
Very often, it so happens that in order to reach a goal state certain
preconditions have to be fulfilled. These preconditions constitute
sub goals. Through the creation of sub goals, the task is broken
down into manageable steps, which help us to reach a final goal
state. Newell and Simon developed a computer program called
General Problem Solver or GPS, which is a program whose basic
strategy is means -ends analysis.
2)The Analogy Approach:
In an analogy, we use a solution to an earlier problem to
help with a new one. Analogies pervade human thinking. Whenever
we try to solve a new problem by referring to a known, familiar
problem, we are using an analogy (Halpern et al.,1990).
Bad Decisions:
a.)Overconfidence: Sometimes our judgments and decisions go
wrong simply because we are more confident than correct. In many
tasks, people tend to overestimate their performance. For example,
many overconfident students expect to finish preparing for exam
ahead of schedule. In fact, the preparation takes more time than
what they predict. Similarly, many people do not realize that there
can be a potential for error in their thinking and believe that they will
have more money next year and merrily take loans and later on findmunotes.in

Page 11

11
it difficult to pay back as they may not get as much pay raise as
they expected.
However, overconfidence has an adaptive value. Research
studies have shown that people who make mistakes in judgment
due to overconfidence live more happily. They make tough
decisions more easily, and they seem to be mo re credible than
others. The wisdom to know when we know a thing and when we
don’t know is born from experience.
b.) Belief Perseverance: Just like we have problem of
overconfidence, we also have problem of belief perseverance -our
tendency to cling to our beliefs in the face of contrary evidence.
Belief perseverance often leads to social conflicts. The more we
come to appreciate why our beliefs might be true, the more tightly
we cling to them. For example, once we have explained to
ourselves why we beli eve a child is ‘gifted’ or has a ‘learning
disability’, we tend to ignore evidence undermining our beliefs.
Once beliefs form and get justified, it takes more compelling
evidence to change them than it did to create them.
To control this tendency, a sim ple trick is to consider the
opposite. When people are asked to imagine and ponder over
opposite findings, they become much less biased in their evaluation
of the evidence.
c.) The Effects of Framing: Framing refers to the way we present
an issue, sways our decisions and judgments. For example,
imagine that two different surgeons are explaining a surgery risk to
ap a t i e n t .O n es u r g e o ns a y st h a t1 0 %p e o p l ed i ed u r i n gt h i s
surgery, while the other surgeon says that 90% people survive this
surgery. The infor mation is same but the effect will be different.
Patients report that risk seems greater when they are told that 10%
people die during this surgery.
Framing can be a powerful persuasion tool. If rightly framed
arguments are presented, it can persuade peo ple to make
decisions that could benefit them or society as a whole.
1.5. THINKING CRITICALLY ABOUT THE FEAR
FACTOR
“Most people reason dramatically, not quantitatively,” said
Oliver Wendell Holmes. After 9/11, many people feared flying more
than drivin g. (In a 2006 Gallup survey, only 40 percent reported
being “not afraid at all” to fly.) Yet Americans were mile for mile —
230 times more likely to die in an automobile crash than on a
commercial flight in the months between 2003and 2005 (Nationalmunotes.in

Page 12

12
Safety Co uncil, 2008). In a late -2001 essay, we calculated that if
because of 9/11 —we flew 20 percent less and instead drove half
those unflown miles, about 800 more people would die in traffic
accidents in the year after 9/11(Myers, 2001). In checking this
estimat e against actual accident data (why didn’t I think of that?),
German psychologist Gerd Gigerenzer (2004) found that the last
three months of 2001 did indeed produce significantly more U.S.
traffic fatalities than the three -month average in the previous fiv e
years. Long after 9/11, the dead terrorists were still killing
Americans. As air travel gradually recovered during 2002 through
2005, U.S. commercial flights carried nearly 2.5 billion passengers,
with no deaths on a major airline big jet (McMurray, 2006 ;M i l l e r ,
2005). Meanwhile, 172,000 Americans died in traffic accidents. For
most people, the most dangerous aspect of airline flying is the drive
to the airport.
1.5.1 Why we fear the wrong things:
Figure: 1.1 Dramatic deaths in bunches breed concern an df e a r :
The memorable South Asian tsunami that killed some 300,000 -
people stirred an outpouring of concern and new tsunami -warning
technology. Meanwhile, a “silent tsunami” of poverty -related malaria
was killing about that many of the world’s children every couple
months, noted Jeffrey Sachs, the head of a United Nations project
aiming to cut extreme poverty in half by 2015(Dugger, 2005).
Why do we judge terrorism to be a greater risk than
accidents —which kill nearly as many per week in just the United
States as did terrorism (2527deaths worldwide) in all of the 1990s
(Johnson, 2001)? Even with the horror of 9/11, more Americans in
2001 died of food poisoning (which scares few) than of terrorism
(which scares many). Psychological science has identified four
influences on our intuitions about risk. Together they explain why
we sometimes fret over remote possibilities while ignoring much
higher probabilities.
munotes.in

Page 13

13
First, we fear what our ancestral history has prepared us to
fear. Human e motions were road tested in the Stone Age. Our old
brain prepares us to fear yesterday’s risks: snakes, lizards, and
spiders (which combined now kill just about no one in developed
countries). And it prepares us to fear confinement and heights, and
therefo re flying.
Second, we fear what we cannot control. Driving we control,
flying we do not.
Third, we fear what is immediate. Threats related to flying
are mostly telescoped into the moments of takeoff and landing,
while the dangers of driving are diffused across many moments to
come, each trivially dangerous. Similarly, many smokers(whose
habit shortens their lives, on average, by about five years) fret
openly before flying (which, averaged across people, shortens life
by one day). Smoking’s toxicity kills in the distant future.
Fourth, we fear what is most readily available in memory.
Powerful, available memories —like the image of United Flight 175
slicing into the World Trade Center —serve as our measuring rods
as we intuitively judge risks. Thousands of s afe car trips have
extinguished our anxieties about driving.
Dramatic Death in Bunches :
Vivid events also distort our comprehension of risks and
probable outcomes. We comprehend disasters that have killed
people dramatically, in bunches. But we fear too l ittle those threats
that will claim lives un -dramatically, one by one, and in the distant
future. As Bill Gates has noted, each year half million children
worldwide —the equivalent of four 747s full of children every day —
die quietly, one by one, from rotavi rus, and we hear nothing of it
(Glass, 2004). Dramatic outcomes makeup gasp; probabilities we
hardly grasp. The point to remember: It is perfectly normal to fear
purposeful violence but smart thinkers will remember this: Check
your fears against the facts and resist those who serve their own
purposes by cultivating a culture of fear. By so doing, we can take
away exaggerated fear.
1.6DO OTHER SPECIES SHARE OUR COGNITIVE
SKILLS?
Other species cognition research examines the processes
used to generate ada ptive or flexible behavior in species. In the
context of animal cognition research, cognition research usually
focuses on questions about the mechanisms involved in specific
capacities, such as learning, memory, perception, or decision -
making. Researchers also investigate animal concepts, beliefs, andmunotes.in

Page 14

14
thoughts. While the representational theory of mind is a common
assumption among animal cognition researchers, there is also the
investigation into the role perception plays in animal learning, and
interest in how much explanatory work can be done by non -
conceptual content, sometimes inspired by work in embodied
cognition (e.g. Barrett 2011). Yes, other species share our cognitive
skills to some extent. They don't share our all cognitive skills as it
is. For example, dogs that understand commands or birds that can
“talk”? Dogs can be trained to follow certain commands such as
‘sit’, ‘come’ and ‘roll over’, but does this mean they understand
language and therefore can use it as well? Dogs are known to be
experts at reading their owners intentions and that they do not
respond to actual words but the tone in which it is said. So,if you
say “bad dog” in a cheerful tone, the dog will wag its tail. If you say
“good dog” in a harsh tone, the dog will put his tail in be tween his
legs. Birds that are in captivity are known to be able to “talk” -it is
believed that it does not mean anything to them and they are
merely copying sounds they hear. There is no doubt that animals
communicate with each other to one degree or anot her in response
to different stimuli such as hunger or fear. Human language is
creative and consists of unique characteristics that give us the
ability to engage in abstract and analytical ways.
1.7 SUMMARY
In this unit we began by explaining the concept of thinking.
We then explained the concept ,m e n t a li m a g e r y and prototypes,
which are the three elements of thinking. Following this, the
concept of problem solving was discussed. In Problem solving
concept we have studied briefly problem solving strategie sa n d
problem solving obstacles. We explained the four methods of
problem solving which included: Algorithms, Heurist ics, Trial &
Error and Insight. We also discussed the five most common
problems in the process of solving a problem i.e. Functional
Fixedne ss, Mental Set and Confirmation bias, Using incomplete or
incorrect representations, Lack of Problem specific knowledge or
expertise. We have also studied decision making in briefly. We
have also studied thinking critically about: the fear factor and why
we fear the wrong things. Towards the end of the unit we have
discussed about other species and cognitive skills.

2.1 INTRODUCTION: LANGUAGE
Langua ge is a system of communication that is governed by
a system of rules (a grammar) and can express an infinite number
of propositions. Language gives us the ability to communicate our
intelligence to others by talking, reading, and writing. As the
psycholog ist Steven Pinker put sit, language is the jewel in the
crown of cognition (Pinker, 1994).
It is important to define language precisely and particularly to
distinguish between language and communication. Althoughmunotes.in

language is often used as a communication system, there are other
communication systems that do not form true languages. For
example, many bees use elaborate dances to tell other bees about
a new found source of food. Although this dance communicates
where the food is, it can only communicate that kind of message -
the dance can’t inform the bees about an interesting sight to see
along the way to the food source. A natural language has two
essential characteristics.
1)Regular and Productive:
It is regular (governed by a system of rules, called gr ammar),
and it is productive, meaning that infinite combinations of things can
be expressed in it.
2)Arbitrariness and Discreteness:
Other characteristics of human languages include
arbitrariness (the lack of necessary resemblance between a word
or sente nce and what it refers to) and discreteness (the system can
be subdivided into recognizable parts, for example -sentences into
words (Hocket, 1960).
2.1.1The Structure of Language
When you have conversation, you first have to listen to the
previous sound s the speaker directs at you. Different languages
have different sounds (called phonemes). Phoneme is the smallest
distinctive sound unit of a language. The study of the ways in which
phonemes can be combined in any given language constitutes the
study of p honology. Next you put the sounds together in some
coherent way, identify the meaningful unit of the language, an
aspect known as morphology. Word ending prefix, tense markers
and the like are critical part of each sentence. Some of the
morphemes (smallest unitthat carry meaning in a given language)
are words, and you also need to identify this and determine the role
each word plays in sentence. To do so, you need to determine the
syntax, or structure, of the sentence. A syntactically correct
sentence does not by itself make for a good conversation.
The sentence must also mean something to the listener.
Semantics is the branch of linguistics and psycholinguistics devotes
to the study of meaning. Finally, for the conversation to work there
must be some flo wo fg i v e n -and-take. Listeners must pay attention
and make certain assumptions, and speakers must craft their
contributions in ways that will make the listener’s job feasible. This
aspect of language, pragmatics, will conclude our discussion on the
Struct ure of language. Keep in mind throughout that although the
various aspects of language will be discussed separately, in actual
conversation they must work together.munotes.in

We will repeatedly bring forth the ideas of the different linguistic
rules (such as phonological rules, syntactic rules) in this section.
These rules make up the grammar of the language and, taken
together, define the ways language works. It is important that
linguists and psychologist used the term grammar in the very
restricted sense, here, meaning “the set of rules for language”. In
particular, grammatical in this context has nothing to do with the
“rules” of “good English” such as “Don’t use ain’t” or “Use
punctuation at the end of the statement.” To a linguist or a
psycholinguist, th e sentence “I ain’t going happily to it” is perfectly
meaningful and “legal” -that is, it follows the “rules” of English that
native speakers observe -and is therefore grammatical. (You
understand it perfectly well, right?). Here grammar refers not to
polite ways of speaking but to ways of speaking that form intelligible
phrases or utterances recognizable as examples of language that a
native speaker of the language might produce. Starting with the
basic sound of speech, spoken language can be broken down i nto
these elements: phonemes, syllables, morphemes, word, Phrase,
and sentence. Apart from this there are many concepts in this topic.
We would discuss all this concepts in details.
Phoneme:
Speech sounds, or phone mes, are made by adjusting the
vocal co rds and moving the tongue, lips, and mouth in wonderfully
precise ways to produce vibrations in the airflow from the lungs.
While hundreds of speech sound can be distinguished on the basis
of their frequency(the number of vibrations per second), their
intensity (the energy in the vibrations) and their pattern of vibrations
over time.
To illustrate phonemes, consider the k phone mein the word key
and cool. Say these words to yourself, and you will realize that the
k sound is different in two words: simply notice the position of your
lips when you are saying them and the “sharper” sound of the K
phones in the word key here, the yare two different phone mes, but
either K sounds can be used in the word key without changing the
meaning of the word; the same can be said for cool. English
speakers do not notice the difference in these k sounds and,
therefore, since they make up no difference in the meaning of the
words and can be substituted for the one another, they can be
grouped together as a single phoneme.
Morpheme:
In a language, the smallest unit that carries meaning; may
be a word or a part of a word (such as a prefix). Although syllables
are the unit of speech perception, and some syllables have
meanings, other language elements are the perceptual units
carrying the meaning of speech. These elements, morphemes, are
the smallest units of meaning in the speech perception. Considermunotes.in

Page 19

the word distasteful. It is composed of three morphemes, each of
which has meaning. The morphemes in this example are dis, taste,
and ful. Dis means “negation” taste is a meaningful word, ful and
means “quality”. Thus, morphemes can be prefixes, words, or
suffixes. Each is composed of syllables, of course, but what makes
them morphemes is that they convey meaning. Morphemes are
discovered by asking people to break words up into the smallest
unit that have meaning for them.
Semantics:
The set of rules by which we derive meaning from
morphemes, words, and sentences in a given language; also, the
study of meaning.
Syntax:
The rule s for combining words into grammatically sensible
sentences in a given language.
Grammar:
In language, a system of rules that enables us to
communicate with and understand others. Words are combined by
the rules of grammar into clauses, and clauses are formed into
sentences. A clause consists of a verb and its associated nouns,
adjectives, and so on. Evidence indicates that clauses, and not
individual words or whole sentences, are the major units of
perceived meaning in speech. When we hear a sentence wi th more
than one clause, we tend to isolate the clauses, analysing the
meaning of each (Bever, 1973).
2.1.2 Language Development
Childhood is the best time for language, no doubt about it.
Young children, the younger the better, are good at it; it is ch ild’s
play. It is a onetime gift to the species. (Lewis Thomas, The Fragile
Species, 1992). Language development is a process starting early
in human life. Anyone who has tried to master a second language
as an adult knows the difficulty of language learni ng. And yet
children learn languages easily and naturally. Children who are not
exposed to language early in their lives will likely never learn one.
Case studies, including Victor the “Wild Child, who was abandoned
as a baby in France and not discovered u ntil he was 12, and Genie,
a child whose parents kept her locked in a closet from 18 months
until 13 years of age, are (fortunately) two of the only known
examples of these deprived children. Both of these children made
some progress in socialization after they were rescued, but neither
of them ever developed language (Rymer, 1993). This is also why it
is important to determine quickly if a child is deaf and to begin
immediately to communicate in sign language. Deaf children who
are not exposed to sign lang uage during their early years will likely
never learn it (Mayberry, Lock, & Kazmi, 2002).munotes.in

Milestones in Language development?
Receptive Language :
Children’s language development moves from simplicity to
complexity. Infants start without language (infantis means “not
speaking”). Yet by 4 months of age, babies can discriminate
speech sounds (Stager & Werker, 1997). They can also read lips:
They prefer to look at a face that matches a sound, so we know
they can recognize that ah comes from wide open lips and from
mouth with corners pulled back (Kuhl &Meltzoff, 1982). This period
marks the beginning of the development of babies’ receptive
language, their ability to comprehend speech –what is said to them
or about them. At seven months and beyond, babies grow in their
power to do what you and I find difficult when listening to an
unfamiliar language: segmenting spoken sounds into individual
words. Moreover, their adeptness at this task, as judged by their
listening patterns, predicts their language abilities at ages 2 and 5
(Newman et al., 2006).
Productive Language:
Babies’ productive language is their ability to produce
words, matures after their receptive language.
Stages of Language Development:
There are mainly five stages of language development. We
would discuss in details all the stages -
1)Babbles Stage:
Beginning at about 04 months. It consists of babbles, many
speech sounds. Yet by 4 months of age, babies can discriminate
speech sounds (Stager & Werker, 1997). Many of these
spontaneously uttered sou nds are consonant -vowel pairs formed
by simply bunching the tongue in the front of the mouth or by
opening or closing the lips.
Beginning at about 10 months, babbling changes and a
trained ear can identify various sounds related to the household
langu age. Without exposure to other languages, babies lose their
ability to hear and produce sounds and tones found outside their
native language. Babbling is not an imitation of adult speech -it
includes sounds from various languages, including the one not
spoken at home. Deaf infants who observe their deaf parents
signing begin to babble more with their hands.
2)One-word stage:
Beginning at about 12 months. The stage in speech
development, during which a child speaks mostly in single words.
They have al ready learnt that sounds carry meanings. They now
begin to use sounds -usually only one recognizable syllable such
as ma or da. But family members quickly learn to understand.munotes.in

Page 21

21
Across the world, baby’s first words are often nouns that label
objects or peop le. This one -word stage may equal a sentence.
3)Two-word, telegraphic speech:
At about 18 months, children’s word slearning explodes from
about a word per week to a word per day. By their second birthday,
most have entered the two -word stage. They start uttering two -word
sentences in telegraphic speech: Like the old -fashioned telegrams
(TERMS ACCEPTED. SEND MONEY), this early form of speech
contains mostly nouns and verbs (Want juice). Alsolike telegrams, it
follows rules of syntax; the words are in a sen sible order. English -
speaking children typically place adjectives before nouns —big
doggy rather than doggy big.
4)Language develops rapidly into complete sentences:
Once children move out of the two -word stage, they quickly
begin uttering longer phrases ( Fromkin &R o d m a n ,1 9 8 3 ) .I ft h e y
get a late start on learning a particular language, for example after
receiving a cochlear implant or being an international adoptee, their
language development still proceeds through the same sequence,
although usually at a faster pace (Ertmer et al., 2007; Snedeker et
al., 2007). By early elementary school, children understand
complex sentences and begin to enjoy the humour conveyed by
double meanings: “You never starve in the desert because of all the
sand -which -is there. ”

Explaining Language Development:
Noam Chomsky argued that all languages do share some
basic elements which he called universal grammar. For example,
all human languages have nouns, verbs and adjectives as
grammatical building blocks. Chomsky believed that we human
beings are born with a built -in predisposition to learn grammar
rules, that is why preschoolers pick up language so readily and use
grammar so well. It happens naturally. But no matter what languagemunotes.in

Page 22

22
we learn, we start speaki ng it mostly in nouns rather than in verbs
and adjectives.
Further, research shows that 7 month olds can learn simple
sentence structures. In an experiment, after repeatedly hearing
syllable sequences that follow one rule, infants listened to syllables
in a different sequence. They could detect the difference between
two patterns later on. This suggested that babies come with a built
in readiness to learn grammatical rules.
Childhood seems to represent critical(sensitive) period for
mastering certain a spects of language before the language learning
window closes. People who learn a second language as adults
usually speak it with the accent of their native language and have
difficulty in mastering the second language. The window on
language learning clos es gradually in early childhood. By about age
7, those who have not been exposed to either a spoken or a signed
language gradually lose their ability to master any language.
Language communication :
A language is said to communicate when others understand
the meaning of our sentences, and we, in turn, understand their
communications, of course, this is not limited to language. We
convey much information to others nonverbally by gesture. When
we speak one of the thousands of languages of the world, we draw
on our underlining knowledge of the rules governing the use of
language. This knowledge about language, or linguistic
competence, as it is called, is used automatically and almost
effortlessly to generate and comprehend meaningful speech.
Linguistic compet ence seems to be universal human species -
typical ability.
2.1.3 Close Up: Living in a silent world:
The discussion so far has been about the use of vocal
speech symbols, or verbal language, in thinking. Can other
language system be used as tools of thou ght? Studies of the deaf
provide an approach to this question. Deaf children with little verbal
language ability score in the normal range on standardized tests of
cognitive performance (Vernon, 1967), and their cognitive and
thinking abilities develop rel atively normally (Furth, 1971). Such
findings have been interpreted as indicating that language plays
little or no role in the thinking or cognitive development of the deaf.
But many of the deaf are taught sign language, and, even if they
are not explicitl y taught such language, it has been found that deaf
children will develop their own (Goldin& Feldman, 1977). This may
indicate that there is an innate human program for language be it
verbal or gestural.munotes.in

Page 23

23
The standard visual -gestural sign languages learned by the
deaf have many features in common with auditory languages. For
example, just as the auditory -vocal languages use combinations of
small number of basic sounds, or phonemes, as they are called to
generate meaningful language, so, too, do the visual -gestural
languages of the deaf make use of a relatively small number of
basic movement combinations for communication. Thus, from
combinations of the basic gestures, an infinity of ideas can be
expressed in the visual -gestural languages. Some studies sugges t
that deaf children who know sign language are better at a variety of
cognitive and thinking tasks than are those without this language
(Vornon &Koh, 1971; Stuckless & Birch, 1966).Thus, those deaf
people whose verbal languages skills are minimal seem to have a
nonverbal language tool of thought.
The challenge of life without hearing may be greatest for
children. Unable to communicate in customary ways, signing
playmates find it difficult to coordinate their play with speaking
playmates. Their school ach ievement may suffer because
academic subjects are rooted in spoken languages. Adolescents
may feel socially excluded with a resulting low self -confidence.
2.1.4The brain and language:
We process complex language information with amazing
speed is an und erstatement. Caplan (1994), reported, for example,
that people typically recognize spoken words after about 125
milliseconds (about one eight of a second) that is, while the word is
still being spoken. Normal word production, estimated over a
number of stu dies, requires us to search through a mental
“dictionary” of about 20,000 items, and we do so at the rate of three
words per second.
Obviously, the brain architecture to support this rapid and
complex cognitive processing must be sophisticated in deed.
Neuropsychologists have been trying to understand what the
underlying brain structures involved with language are, where they
are located, and how they operate. In this topic, we will see two
important language disorders which are related to brain an d
language.
Adults whose hearing becomes impaired later in life also
face challenges. When older people with hearing loss must expend
efforts to hear words, they have less remaining cognitive capacity
available to remember and comprehend them. It has been found
that people with hearing loss, especially those not wearing hearing
aid, have reported feeling sadder, being less socially engaged and
more often experiencing others’ irritation. They may also
experience a sort of shyness. Henry Kisor (1990) very ap tly said,
“we can be self -effacing and diffident to the point of invisibility.munotes.in

Page 24

24
Sometimes this tendency can be crippling. I must fight it all the
time”. Helen Keller, both deaf and blind, also noted that “Blindness
cuts people off from things. Deafness cuts people off from people”.
Broca’s Aphasia:
Interest in localizing language function in the brain dates
back at least to the 1800s, when a French physician with interests
in anthropology and ethnography, Pierre Paul Broca, read a paper
in 1861 at the mee ting of the society Anthropologist in Paris. The
paper reported on a patient, nicknamed “Tan” because he had lost
the ability to speak any word save for tan. Shortly after the patient
died, his brain was examined and found to have a lesion in the left
frontal lobe. The very next day, Broca reported this exciting (for
science, not for the patient or his family, probably) finding (Posner
&Raichle, 1994). The area of the brain, henceforth known as
Broca’s area, is shown in the figure 2.7.A. It is also called
expressive aphasia. A Broca’s aphasia appeared to leave language
reception and processing undisturbed. In 1865, Broca reported that
after damage to an area of the left frontal lobe a person would
struggle to speak words while still being able to sing famili ar songs
and comprehend speech.
Fig.2.1: Brain structure involved with languages .
Wernicke’s Aphasia:
About 13 years later, in 1874, a German neurologist Carl
Wernicke identified another brain area that, if damaged by a small
lesion (often result o f a stroke), left patients with extreme difficulty
in comprehending (but not producing) spoken language (Posner &
Raichle, 1994). (Not surprisingly, this area has come to be called
Wernicke’s area, and it is also shown in figure 2.7.A. It is also
called re ceptive aphasia. People could speak words and sentences
(although the language was often gibberish). Damage to
Wernicke’s area also disrupts understanding.
But today, Functional MRI scan shows that different neural
networks are activated by nouns and ve rbs, or objects and actions,munotes.in

Page 25

by different vowels and by reading stories of visual vs. motor
experiences. It was also found that jokes that play on meaning are
processed in a different area of the brain than jokes that play on the
words. The main point is t hat in processing language, the brain
operates by dividing its mental functions –speaking, perceiving,
thinking, remembering into sub functions. Localized trauma that
destroys one of these neural work teams may cause people to lose
just one aspect of proc essing.
2.1.5Do other species have language?
Language is considered to be a very complex form of
communication that occurs among the human race. It is a set of
verbal and non -verbal conventions that humans use to express
their ideas and wants. Humans us e words while talking to express
their needs and wants and they cry, slouch and make faces when
they want to express feelings. Animals, or in other words non -
humans also show signs of communication such as a dog wagging
its tail when excited or a bird sing ing a song to attract the opposite
sex. However, do animals have their language? Researchers say
that animals ornon-humans, do not have a true language like
humans. However, they do communicate with each other through
sounds and gestures. Animals have a n umber of in -born qualities
they use to signal their feelings, but these are not like the formed
words we see in the human language. Human children show these
same forms of communication as babies when crying and
gesturing. But they slowly learn the words o f the language and use
this as form of communication.
If human children were separated at birth away from humans
they would not learn the words of the language and would not be
able to communicate with other humans. They would resort to
sounds and gesture s as their primary form of communication.
However, in the animal kingdom if they are reared alone from birth
they are still able to behave and communicate in the same way as
other species of their kind.
So what about animals such as dogs that understand
commands or birds that can “talk”? Dogs can be trained to follow
certain commands such as ‘sit’, ‘come’ and ‘roll over’, but does this
mean they understand language and therefore can use it as well?
Dogs are known to be experts at reading their owners inten tions
and that they do not respond to actual words but the tone in which it
is said. So if you say “bad dog” in a cheerful tone, the dog will wag
its tail. If you say “good dog” in a harsh tone, the dog will put his tail
in between his legs. Birds that are in captivity are known to be able
to “talk” -it is believed that it does not mean anything to them and
they are merely copying sounds they hear. There is no doubt that
animals communicate with each other to one degree or another in
response to different s timuli such as hunger or fear. Humanmunotes.in

language is creative and consists of unique characteristics that give
us the ability to engage in abstract and analytical ways.
2.2THINKING AND LANGUAGE
Philip Dale very correctly said that thinking is more than
language and language is more than thinking, but thinking and
language are related and in this topic we will describe some of the
ways in which they are related.
Every day we use language in our thinking. For many
people, much of the time, a good deal of thi nking involves the use
of word symbols and the rules of grammar to join the words into
phrases and sentences. The words, their meanings and rules for
joining them together are stored in our semantic long term
memories. When we think with language, we draw on this store of
information to use language as tool of thought.
Some theories take a more extreme view of the role
language in thinking; they claim that language can actually
determine the thoughts we are capable of having. But this linguistic
relativity hypothesis, as it is called, has been under increasing
attack in recent years.
Because so much thinking involves language, the idea arose
in psychology that thinking was actually a kind of inner speech, a
kind of “talking to yourself under your breath.” According to this
idea, people make small movement of the vocal apparatus when
they think and carry on their thinking by talking to themselves. A
number of experiments have indicated that movements of the vocal
apparatus may indeed accompany thought, but o ther experiments
have made it clear that such movements are not necessary for
thinking (Smith et al., 1947). In one heroic experiment, the subject,
a physician, was completely paralyzed by means of a drug. He
literally could not move a muscle, and his brea thing was done for
him by an iron lung. The paralyzing drug, however, did not affect
the way his brain worked; it merely acted on the drug, the subject
was given certain verbal problems to solve; he could not answer, of
course, because the muscles necessar y for speaking were
paralyzed. There is no way to be certain that, thinking while under
the influence of the drug, but all indications are that he was unable
to do so because after the paralysis was removed by a
counteracting drug, he clearly remembered wh at had taken place
while he was drugged and promptly gave the answer to problems.
2.2.1 Language influences thinking:
There are at least 5,000 living languages in the world about
140 of them are spoken by a million or more people. Is a particularmunotes.in

Page 27

27
languag e merely a convenient set of symbols for the
communication of our thoughts? According to the linguist Benjamin
L. Whorf, the answer is no. Whorf argued that the higher levels of
thinking require language and that the characteristics of particular
language actually shape the way that users of the language think
about things. There are two ideas here. One is that thinking
requires language, the other has come to be called the linguistic
relativity hypothesis . Most of the interest has focused on this
hypothesi s. In its strongest form, it says that the particular language
people used determines how they see the world.
Whorf based his hypothesis on studies of North American
Indian languages, but his hypothesis is said to hold for all
languages. He found many dif ferences between these languages
and European ones and argued that such differences predispose
their users to think in different ways. For example, the grammar of a
language dictates how people describe changes in the
environment. Since the basic unit of E nglish grammar are nouns
and verbs, English -speaking people commonly think in terms of
“things” and “actions” Whorf found that people using other
languages do not necessarily divide situation up this way.
Furthermore, all languages have some words for whic hn o
equivalents can be found in any other language. The German word
weltanschauungsfor instance, means something like “a general
world view, or a general philosophy of the world”. There is no word
with this precise meaning in English. In addition, languag es
categorize events in various ways. Eskimos are said to use some
four different words for snow, while English has only one. According
to the linguistic relatively hypothesis. Eskimos can think about snow
with greater precision than English speaking can p eople and have
different conception of what snow is, the Hopi language has single
word for all flying objects their than birds. The hypothesis states
that Hopi speakers thinks differently about flying objects than do
speakers of languages that do not categ orize the world in this way.
TheHanno people of the Philippine, islands are said to have names
for 92 varieties of rice, but all 92 varieties are, for the English
speaker, simply rice(Con, 1954 cited in brown, 1965).
The linguistic relativity hypothesis is controversial. Many
linguistic have argued that the hypothesis is circular Whorf found
that languages differ in their grammar and in the concepts they can
express from the hypothesized that thinking must also differ among
the users of this different la nguages. However, the differences in
the thinking are themselves assessed by the way of the language is
used. What is hidden are ways of assessing conceptions of the
word independently of language. The few experiments that have
attempted this have had inco nclusive results. Perhaps it is not so
much a matter of what can be thought about by users of a language
as it is of how easy it is to think about certain things. English -munotes.in

Page 28

28
speaking thinkers can think about the concept of the “world view”
even if they do not have a convenient word for it. English speakers
can think about different kinds of snow, even have to use more
words to describe it.
More recently, interest has shifted away from relativity to
universals in thinking perhaps the basic thought processes in
thinking are similar, even though languages differ widely. Colour
perception provides an example of the possible universality of
thinking despite the different ways in which different languages
designate colours. It has been found that certain “focal” c olours -a
maximum of 11 -are chosen from a colour chart by speakers of
widely differing languages. Furthermore, it has been shown that
thinking can be influenced by these focal colours even when the
language does not have names for them. This is contrary to what
might be expected from the linguistic relativity hypothesis. For
example, Eleanor Rrosch has done experiments with the Dani
people of the New Guinea. The Dani have only “black” and mola for
“white”. The Dani subjects in these experiments studies a col our
chart arbitrary names were assigned to eight of the focal colours
and eight of the non -focal colours on the chart. The Dani learn the
names assigned to the focal colours more rapidly and remembered
them better than they did those given to the other col ors. Thus even
though the Dani do not have names for the focal colors in their
language, their thinking is influenced by them.
2.2.2 Thinking inimages
To a large degree, the availability of the symbols that we use
in thinking are often words and languag e, and therefore thinking
and language are closely related. A language makes available
hundreds of thousands of potential language symbols is what
makes human thinking so much more sophisticated than the
thinking of other animals. Although language is a po werful tool in
human thought, as when we “talk to ourselves” internally, images
are another important type of symbol used in thinking.
People vary remarkable in how much they use images in
their thinking. A few report that they almost never use mental
pictures, so they must be doing their thinking with words, or
verbally; others that most of their thinking is done in image form.
When we use images to think, they are not usually complete
“pictures in the head”. They are usually incomplete. Consider the
imagery you use, if you use it at all, in solving the following
problems (Huttenlocher, 1973) .Imagine that you are standing on a
certain street corner in a section of a city you know well. How would
you walk or drive from this point to some other part of the city?
Here is another problem in which you might use imagery:
from where on earth could you walk first 1 mile south, then 1 milemunotes.in

east, then 1 mile north, and end up exactly where you began? Did
you use imagery in trying to solve this problem? If so, wha tw a s
your imagery like?
When solving problems like these, most people report that
their images are incomplete. To solve the first problem, people
usually make a visual map, but it is a strange one. Although it
shows turns, the lines connecting the turns are of no particular
length. In solving the second problem (the answer is the north
pole), people imagine a globe -but not the whole globe, only the
polar region. Such problem -solving images contain only a few
details -say, of sidewalks, roads, buildings, or color -although some
people may imagine snow when they think of the north pole. In
general, the images are abstractions of certain features from
previous experience.
The incomplete, abstract images most of us use in thinking
seem to be constructed from elements stored in long term memory.
The constructive process involved in imagery has been studied by
means of experiment in which people were asked to form images of
various sizes. For example, an elephant might be imaged as the
size of a mouse, or mouse imaged as the size of an elephant.
Variations of this sort in the sizes of images indicate that images
are constructions. Even more interesting, however, are studies
indicating that the ease with which information is found in an image
depends on the size (and other aspects) of the image constructed
(Kosslyn, 1983).
2.3 SUMMARY
In this unit we began by explaining the concept of language
and its structure. We then explained how language developed in
human beings. We have also studied the stages of lan guage
development. We explained the relationship between thinking and
language and how language influences thinking. The concept of
thinking in images and association between brain and language
was also explained. In “brain and language” topic we studied t wo
important language disorders (Broca’s aphasia and Wernicke’s
aphasia). Following this we discussed about living in a silent world
and do other species have language.

retardation and giftedness. We would discuss in detail about the
origins of intelligence testing and different ways to assess
intelligence. After this, we would briefly discuss modern tests of
mental abilities such as Binet Mental Ab ility Test, Stanford Binet
and The Wechsler Tests. It should be remembered that Intelligence
is one of the most important and unique ability that human beings
possess. The term intelligence was popularized by Sir Francis
Galton, Alfred Binet and others. In telligence refers to the cognitive
ability of an individual to learn from experience, to reason well, and
to cope with the demands of daily living. Some important concepts
and topics related to intelligence such as emotional intelligence,
Intelligence and creativity, the nature v/s nurture controversy and
the bell curve would also be discussed in brief. Towards the end of
the unit we would study principles of test construction .
Intelligence is a key construct employed to know how
individuals differ from on e another. It also provides an
understanding of how people adapt their behaviour according to the
environment they live in. In this chapter, we would learn about
intelligence in its various forms.
Definition:
Psychological notion of intelligence is quite different from the
common notion of intelligence. If you watch an intelligent person,
you are likely to see in her/him with attributes like mental alertness,
ready wit, quickness in learning and ability to understand
relationships. Intelligence is not a q uality like height or weight,
which has the same meaning for everyone around the globe.
People assign the term intelligence to the qualities that enable
success in their own time and in their own culture. There are
different definitions of intelligence giv en by different psychologist,
some of which are given below.
Alfred Binet was one of the first psychologist who worked on
intelligence. According to him, Intelligence is the ability to judge
well, understand well and reason well (Alfred Binet, 1973).
Acco rding to Wechsler, Intelligence is the global and aggregate
capacity of an individual to act purposefully, to think rationally
and to deal effectively with his/her environment. (Wechsler,
1950).
Other psychologists such as Gardner and Sternberg have
define d intelligence as well. Intelligent individual not only adapt
to their environment but also actively modifies or shapes it
(Gardner & Sternberg).
In simple words, intelligence is synthesis of one’s abilities.
Binet assumes intelligence as a general capaci ty for
comprehension and reasoning that manifests itself in various ways,
another psychologist, Charles Spearman, proposed that allmunotes.in

Page 33

33
individuals possess a general intelligence factor in varying
amounts. In contrast to Spearman. Louis Thurstone felt that
intelligence could be broken down into a number of primary
abilities. Rejecting all these theories, Guilford states that many
aspects of intelligence tends to be ignored when items are lumped
together to form tests.
Important Concepts in Intelligence:
Indiv idual Differences in Intelligence:
It is often said that no two individuals are exact duplicates;
they differ from each other in some way or the other. Hence the job
of the psychologist is to identify and understand this uniqueness in
individuals. Such a similarity or difference between persons reveals
individual differences. It happens in our day -to-day life when we
see people around us. A question comes to mind; how and why
people appear similar or different to each other? For example,
when we think abou t their physical appearance, we often ask
ourselves why some people have dark or fair complexion, why
some people are tall and some are short, why some are thin and
why some are very fat. When we think about their psychological
characteristics we often com e across people who are very talkative
or less talkative, some laugh too much whereas others take much
time even to smile and some are very friendly whereas some prefer
to be alone. In psychology, these are called individual differences
referring to the ex tent and kind of variations or similarities among
people on some of the important psychological aspects such as
intelligence.
When we speak Individual differences in terms of
intelligence, individual difference occur due to interaction of genetic
and en vironmental factors. We inherit certain characteristics from
our parents through genetic codes. The phenotype or the
expressed forms of our characteristics depend on contributions of
the socio -cultural environment. This is the reason why we are not
exactly like our parents and our parents not exactly like our
grandparents. We do share similarities with our parents in respect
of many physical attributes like height, colour of eyes, shape of
nose etc. We also inherit certain cognitive, emotional and other
characteristics from our parents like intellectual competence, love
for sport, creativity etc. However, our own characteristics develop
largely by the support from the environment in which we live.
Extremes of Intelligence: Retardation and Giftedness :
The r esults of studies assessing the measurement of
intelligence show that IQ is distributed in the population in the form
of a normal distribution curve, which the pattern of scores is usually
observed in a variable that clusters around its average. In a norma l
distribution, the bulk of the scores fall toward the middle, with many
fewer scores falling at the extremes. The normal distribution ofmunotes.in

Page 34

34
intelligence (Figure11.2. Distribution of IQ Scores in the General
Population") shows that on IQ tests, as well as on most other
measures, the majority of people cluster around the average (in this
case, where IQ = 100), and fewer are either very smart or very dull.
Because the standard deviation of an IQ test is about 15, this
means that about 2% of people score above an IQ of 130 (often
considered the threshold for giftedness), and about the same
percentage score below an IQ of 70 (often being considered the
threshold for mental retardation).
The normal distribution of IQ scores in the general
population shows that mo st people have about average
intelligence, while very few have extremely high or extremely low
intelligence.
Figure 3.1:Normal Distribution Curve of Intelligence: Bell Curve
Retardation:
One cause of mental retardation is Down syndrome, a
chromosomal disorder leading to mental retardation caused by the
presence of all or part of an extra 21st chromosome. The incidence
of Down syndrome is estimated at 1 per 800 to 1,000 births,
although its prevalence rises sharply in those born to older
mothers. People with Down syndrome typically exhibit a distinctive
pattern of physical features, including a flat nose, upwardly slanted
eyes, a protruding tongue, and a short neck.
Societal attitudes toward individuals with mental retardation
have chan ged over the past decades. We no longer use terms such
as mad, idiot to describe these people, although these were the
official psychological terms used to describe degrees of retardation
in the past. Laws such as the Person with Disabilities Act (PWD)
have made it illegal to discriminate on the basis of mental and
physical disability, and there has been a trend to bring the mentally
retarded out of institutions and into our workplaces and schools.

Giftedness:
Having extremely high IQ is clearly less of ap r o b l e mt h a n
having extremely low IQ, but there may also be challenges to being
particularly smart. It is often assumed that schoolchildren who are
labeled as gifted may have adjustment problems that make it more
difficult for them to create social rela tionships. To study gifted
children, Lewis Terman and his colleagues (Terman & Oden, 1959)
selected about 1,500 high school students who scored in the top
1% on the Stanford -Binet and similar IQ tests (i.e., who had IQs of
about 135 or higher), and tracked them for more than seven
decades (the children became known as the termites and are still
being studied today). This study found, first, that these students
were not unhealthy or poorly adjusted but rather were above
average in physical health and were ta ller and heavier than
individuals in the general population. The students also had above
average social relationships for instance, being less likely to divorce
than the average person (Seagoe, 1975).
As you might expect based on our discussion of intel ligence,
kids who are gifted have higher scores on general intelligence (g).
But there are also different types of giftedness. Some children are
particularly good at math or science, some at automobile repair or
carpentry, some at music or art, some at spo rts or leadership, and
so on. There is a lively debate among scholars about whether it is
appropriate or beneficial to label some children as gifted and
talented in school and to provide them with accelerated special
classes and other programs that are not available to everyone.
Although doing so may help the gifted kids (Colangelo &Assouline,
2009), it also may isolate them from their peers and make such
provisions unavailable to those who are not classified as gifted.
There is IQ classification given by Wechsler for understanding of IQ
range. Classification of IQ range is given below.
No. IQ Range IQ Classification
1. 130 and Above Very Superior
2. 120-129 Superior
3. 110-119 Above Average Intelligence
4. 90-109 Average Intelligence
5. 80-89 Below Average Intelligence
6. 70-79 Borderline Intelligence
7. 55-69 Mild Mental Retardation
8. 40-54 Moderate Mental Retardation
9. 25-39 Severe Mental Retardation
10. 24 and Below Profound Mental Retardation

Nature v/s Nurture Controversy:
Intelligence has both genetic and environmental causes, and
these have been systematically studied through a large number of
twin and adoption studies (Neisser et al., 1996; Plomin, DeFries,
Craig, & McG uffin, 2003). These studies have found that between
40% and 80% of the variability in IQ is due to genetics, meaning
that overall genetics plays a bigger role than does environment in
creating IQ differences among individuals (Plomin &Spinath,
2004). The IQs of identical twins correlate very highly (r = .86),
much higher than do the scores of fraternal twins who are less
genetically similar (r = .60). And the correlations between the IQs of
parents and their biological children (r = .42) is significantly g reater
than the correlation between parents and adopted children (r = .19).
The role of genetics gets stronger as children get older. The
intelligence of very young children (less than 3 years old) does not
predict adult intelligence, but by age 7 it does, and IQ scores
remain very stable in adulthood (Deary, Whiteman, Starr, Whalley,
&F o x ,2 0 0 4 ) .
But there is also evidence for the role of nurture, indicating
that individuals are not born with fixed, unchangeable levels of
intelligence. Twins raised tog ether in the same home have more
similar IQs than do twins who are raised in different homes, and
fraternal twins have more similar IQs than do non -twin siblings,
which is likely due to the fact that they are treated more similarly
than are siblings. The f act that intelligence becomes more stable as
we get older provides evidence that early environmental
experiences matter more than later ones. Environmental factors
also explain a greater proportion of the variance in intelligence for
children from lower -class households than they do for children from
upper -class households (Turkheimer, Haley, Waldron, D‘Onofrio, &
Gottesman, 2003). This is because most upper -class households
tend to provide a safe, nutritious, and supporting environment for
children, wherea s these factors are more variable in lower -class
households.
Social and economic deprivation can adversely affect IQ.
Children from households in poverty have lower IQs than do
children from households with more resources even when other
factors such as education, race, and parenting are controlled
(Brooks -Gunn & Duncan, 1997). Poverty may lead to diets that are
under -nourishing or lacking in appropriate vitamins, and poor
children may also be more likely to be exposed to toxins such as
lead in drinking water, dust, or paint chips (Bellinger &N e e d l e m a n ,
2003). Both of these factors can slow brain development and
reduce intelligence. If impoverished environments can harm
intelligence, we might wonder whether enriched environments can
improve it. Governmen t-funded after -school programs such as
Head Start are designed to help children learn. Research has foundmunotes.in

Page 37

37
that attending such programs may increase intelligence for a short
time, but these increases rarely last after the programs end
(McLoyd, 1998; Perkins &Grotzer, 1997). Intelligence is improved
by education; the number of years a person has spent in school
correlates at about r = .6 with IQ (Ceci, 1991).
It is important to remember that the relative roles of nature
and nurture can never be completely separated. A child who has
higher than average intelligence will be treated differently than a
child who has lower than average intelligence, and these
differences in behaviors will likely amplify initial differences. This
means that modest genetic differ ences can be multiplied into big
differences over time.
The Bell Curve:
Richard Herrinstein and Charles Murray in 1994 published
an important book called as “The Bell Curve” which has become
highly controversial and had made certain conclusion concernin g
intelligence, race and genetics. According to Herrenstein and
Wilson (1994) intelligence is an important asset in am o d e r n
society. The demand for intelligence in modern society has created
two groups in society. One group consists of highly intelligent
individuals who hold good jobs and earn more. Due to their high
intelligence, they are paid more and they progress economically as
well as socially. On the other hand, are individuals, who, because
of their low intelligence, hold low status jobs and are pa id less.
Consequently, their economic and social status is also low. Thus,
according to Herrenstein and Murray (1994) one’s intelligence
determines one’s occupational success and one’s social status. Its
central point is that intelligence is a better predi ctor of many factors
including financial income, job performance, unwed pregnancy, and
crime than parents' Socioeconomic or education level. Also, the
book argued that those with high intelligence, which it called the
"cognitive elite", are becoming separa ted from the general
population of those with average and below -average intelligence
and that this was a dangerous social trend.
Thus, in The Bell Curve, Herrnstein and Murray set out to
prove that American society was becoming increasingly
meritocratic , in the sense that wealth and other positive social
outcomes were being distributed more and more according to
people's intelligence and less and less according to their social
backgrounds.
The Bell Curve has become highly controversial. The Bell
Curve is not a scientific work. It was not written by experts, and it
has a specific political agenda. According to experts the book has
many statistical errors and ignored the effects of environment and
culture in determining his/her success in life.munotes.in

Page 38

Social Det erminants & Biological Determinants of Intelligence:
There are two basic factors which influence the human
intelligence. These two factors are biological and social. The
heredity -environment issue, debated in regard to many aspects of
human behaviour, has focused most intensely on the area of
intelligence. Few experts doubt that there is some genetic basis for
intelligence, but opinion differ as to the relative contribution of
heredity and environment.
Most of the evidence bearing on the inheritance of th e
intelligence comes from studies correlating IQs between person of
various degree of genetic relationship. The average correlation
between the IQs of parents and their natural children is 50;
between parents and their adopted children the correlation is a bout
25. Identical twins, because they develop from a single egg. Share
precisely the same heredity; the correlation between their IQs very
high –about 90. The IQs of fraternal twins (who are genetically no
more alike than ordinary siblings, since they dev elop from separate
eggs) correlated higher, .75, than those of fraternal twins reared
together.
Note that being reared in the same home situation tends to
increase IQ similarity, even for individual who are unrelated.
Although adopted children resemble t heir natural parents on the
basis of their natural parent’s ability (Skodak and Skeels, 1949).
Racial Differences:
After discussing generic contribution to intelligence, it is
obvious that there are racial differences in intelligence. Because of
the rec ent issue on the question of whether blacks are innately less
intelligent than whites. In view of the heated controversy centered
on this issue and its significance for social policy, it is important that
we examine the available evidence. On standard inte lligence tests
black Americans, as a group, score 10 to 15 IQ points lower than
while Americans, as a group. This fact is not a debate but revolves
around how to interpret the difference. Some possible explanations
should be apparent from what we have alre ady said about the
nature of IQ tests and the influence of environmental factor on
tested intelligence. For example, most intelligence have been
standardized on white populations. Since black and whites
generally grow up in quite different environments and have different
experiences, the contents of such tests may not be appropriate for
blacks. And a black child may react differently to being tested
(particularly if he or she is being tested by a white examiner) than a
white child. Thus, the whole issue of estimating black intelligence is
complicated by the questions of whether the tests are appropriate
and whether the data obtained by white testers represent an
unbiased measure of IQ.munotes.in

3.1.1Is intelligence one general ability or several specific
abilities?
In the early 1900s, the French psychologist Alfred Binet
(1857 –1914) and his colleague Henri Simon (1872 –1961) began
working in Paris to develop a measure that would differentiate
students who were expected to be better learners from students
who were ex pected to be slower learners. The goal was to help
teachers better educate these two groups of students. Binet and
Simon developed what most psychologists today regard as the first
intelligence test, which consisted of a wide variety of questions that
included the ability to name objects, define words, draw pictures,
complete sentences, compare items, and construct sentences.
Binet and Simon (Binet, Simon, & Town, 1915; Siegler,
1992) believed that the questions they asked their students, even
though they were on the surface dissimilar, all assessed the basic
abilities to understand, reason, and make judgments. And it turned
out that the correlations among these different types of measures
were in fact all positive; students who got one item correct were
more likely to also get other items correct, even though the
questions themselves were very different.
On the basis of these results, the psychologist Charles
Spearman (1863 –1945) hypothesized that there must be a single
underlying construct that all of t hese items measure. He called the
construct that the different abilities and skills measured on
intelligence tests have in common the general intelligence factor
(g). Virtually all psychologists now believe that there is a
generalized intelligence factor, g, that relates to abstract thinking
and that includes the abilities to acquire knowledge, to reason
abstractly, to adapt to novel situations, and to benefit from
instruction and experience (Gottfredson, 1997; Sternberg, 2003).
Although there is general a greement among psychologists
that g exists, there is also evidence for specific intelligence (s), a
measure of specific skills in narrow domains. One empirical result
in support of the idea of "s"comes from intelligence tests
themselves. Although the diff erent types of questions do correlate
with each other, some items correlate more highly with each other
than doother items; they form clusters or clumps of intelligences.
Theory of Multiple Intelligence:
According to American psychologist Howard Gardner (1983) we do
not have one underlying general intelligence, but instead have
multiple intelligences. The nine types of intelligence identified by
Howard Gardner are as follows:munotes.in

Page 40

40
Linguistic Intelligence: Children with this kind of intelligence
enjoy writing , reading, telling stories or doing crossword
puzzles. Linguistic intelligence involves aptitude with speech
and language and is exemplified by poet T. S. Eliot.
Logical -Mathematical Intelligence: Children with lots of logical
intelligence are interested in patterns, categories and
relationship s. They are drawn to arithmetic problems, strategy
games and experiments. Physicist Albert Einstein is ag o o d
example of this intelligence.
Spatial Intelligence: It is used to perceive visual and spatial
information and to conceptualize the world in tasks like
navigation and in art. Painter Pablo Picasso represents a
person of high spatial intelligence.
Musical intelligence: It is the ability to perform and appreciate
music, is represented by composer A. R. Rahman a nd Rahul
Dev Burman (R.D. Burman).
Bodily -kinaesthetic intelligence: It is the ability to use one’s
body or portions of it in various activities, such as dancing,
athletics, acting, surgery, and magic. Martha Graham, the
famous dancer and choreographer, i sag o o de x a m p l eo f bodily -
kinaesthetic intelligence. It is the type of ability shown by the
gifted athletes, dancers or super surgeons who have great
control over their body, hand and finger movements.
Interpersonal intelligence: It involves understandin go t h e r s
and acting on that understanding. It is the type of ability shown
by those who can easily infer other people's mood,
temperaments, or intentions and motivations.
Intrapersonal intelligence: It is the ability to understand one’s
self and is typifi ed by the leader Mohandas Gandhi. It is the
ability shown by someone who has great insight into his/her own
feelings and emotions.
Naturalist Intelligence : the ability to recognize and classify
plants, animals, and minerals. Naturalist Charles Darwin is an
example of this intelligence. Naturalistic Intelligence is defined
as the ability to observe and/or interact with diverse species in
nature. The type of ability shown by biologists or
environmentalist
Existentialist: It is the ability to see the “big p icture of the
human world by asking questions about life, death and the
ultimate reality of human existence.munotes.in

Page 41

3.1.2 Intelligence and creativity:
One important debate in understanding the variations in
creativity has been the relationship of creativity with intelligence.
Let us take an example of two students in a class. Savita is
regarded by her teacher as an excellent student. She does her
work on time, scores the highest grades in her class, listens to
instructions with care, grasps quickly, reproduces ac curately but
she rarely comes out with ideas which are her own. Rima is another
student who is just average in her studies and has not achieved
high grades consistently. She prefers to learn on her own. She
improvises new ways of helping her mother at home and comes up
with new ways of doing her work and assignment. The former is
considered to be more intelligent and the latter as more creative.
Thus, a person who has the ability to learn faster and reproduced
accurately may be considered intelligent more t han creative unless
she/he devises new ways of learning and doing.
Terman, in the 1920s, found that persons with IQ were not
necessarily creative. At the same time, creative ideas could come
from persons who did not have a very high IQ. Other researchers
have shown that not even one of those identified as gifted, followed
up throughout their adult life, had become well -known for creativity
in some field. Researchers have also found that both high and low
level of creativity can be found in highly intellig ent children and also
children of average intelligence. The same person, thus, can be
creative as well as intelligent but it is not necessary that intelligent
ones, in the conventional sense, must be creative. Intelligence,
therefore, by itself does not en sure creativity.
Researchers have found that the relationship between
creativity and intelligence is positive. All creative acts require some
minimum ability to acquire knowledge and capacity to comprehend,
retain and retrieve. Creative writers, for exam ple, need facility in
dealing with language. The artist must understand the effect that
will be produced by a particular technique of painting, a scientist
must be able to reason and so on. Hence, a certain level of
intelligence is required for creativity but beyond that intelligence
dose not correlate well with creativity. It can be concluded that
creativity can take many forms and blends. Some may have more
of intellectual attributes, others may have more of attributes
associated with creativity. Yet ther e is more to creativity than what
intelligence tests reveal. Intelligence tests require convergent
thinking while creativity tests require divergent thinking. Injury to
certain areas of the frontal lobes can leave reading, writing and
arithmetic skills int act but destroy imagination. Sternberg et.al. have
identified 5 components of creativity -munotes.in

Page 42

42
1.Expertise –awell-developed base of knowledge -furnishes the
ideas, images and phrases we use as mental building blocks. The
more blocks we have, the more chanc es we have to combine them
in novel way.
2.Imaginative Thinking Skill –It provides the ability to see things
in a novel way, to recognize patterns, and to make connections.
Having mastered a problem’s basic elements, we redefine or
explore it in a new way .
3.AVenturesome Personality –A venturesome personality seeks
new experiences, tolerates ambiguity and risk, and perseveres in
overcoming obstacles. For example, Wiles said he labored in near -
isolation from the mathematics community partly to stay focu sed
and avoid distractions.
4. Intrinsic Motivation –Intrinsic motivation is being driven more
by interest, satisfaction and challenge than by external pressures.
Creative people focus less on extrinsic motivators such as meeting
deadlines, impressing peo ple, or making money –than on the
pleasure and stimulation of the work itself. When Newton was
asked how he solved such difficult problems, he said by thinking
about them all the time.
5. A Creative Environment sparks, supports, and refines creative
ideas . After studying the careers of 2026 famous scientists and
inventors, Dean keith Simonton (1992) concluded that most of
these men were mentored, challenged and supported by their
colleagues. Many had the emotional intelligence needed to network
effectively with peers. Creativity -fostering environments support
innovation, team building and communication. They also support
contemplation.
3.1.3 Emotional intelligence:
Most psychologists have considered intelligence a cognitive
ability, people also use thei r emotions to help them solve problems
and relate effectively to others. Emotional intelligence refers to the
ability to accurately identify, assess, and understand emotions, as
well as to effectively control one’s own emotions (Feldman -Barrett
&S a l o v e y , 2002; Mayer, Salovey, & Caruso, 2000).
This concept was first introduced by Salovey and Mayer.
According to them, Intelligence is the ability to monitor one’s own
and others emotions, to discriminate among emotions and to use
the information to guide one ’s thinking and actions. The idea of
emotional intelligence is seen in Howard Gardner‘s interpersonal
intelligence (the capacity to understand the emotions, intentions,
motivations, and desires of other people) and intrapersonal
intelligence (the capacity to understand oneself, including one‘s
emotions).munotes.in

Emotional Quotient (EQ):
Emotional Quotient (EQ) is used to express emotional
intelligence in the same way as Intelligent Quotient (IQ) is used to
express intelligence. Emotional Quotient (EQ) is a ratio concept
and is a score of emotional intelligence obtained by dividing
chronological age by emotional age and multiplying by 100. The
formula of Emotional Quotient (IQ) is given below.
Emotional Quotient (EQ) = Emotional Age/
Chronological Age* 100
Emot ional intelligence is a set of skills that underlie accurate
appraisal, expression and regulation of emotions. It is the feeling
side of intelligence. A good IQ and scholastic record is not enough
to be successful in life. You may find many people who are
academically talented but are unsuccessful in their own life. They
experience problems in their life, workplace and interpersonal
relationships. What do they lack? Some psychologists believe that
the source of their difficulty may be lack of emotional inte lligence. In
simple words, emotional intelligence refers to the ability to process
emotional information accurately and efficiently. There are some
characteristics of emotional intelligent person. Person who are high
on emotional intelligence who possess f ollowing characteristics.
Characteristics of Emotional Intelligent Person :
Perceive and be sensitive to your feelings and emotions.
Perceive and be sensitive to various types of emotions in others
by noting their body language, voice, tone and facial
expressions.
Relate your emotions to your thoughts so that you take them
into account while solving problems and taking decisions.
Understand the powerful influence of the nature and intensity of
your emotions.
Control and regulate your emotions and their expr essions while
dealing with self and others.
Daniel Goleman, an American author and journalist,
popularized the concept in his book Emotional Intelligence (1995).
He expanded the concept to include general social competence.
The importance of emotional in telligence has been very well
brought out in the following words by Daniel Goleman “Emotional
Intelligence is a master aptitude, a capacity that profoundly affects
all other abilities, either facilitating or interfering with them.
According to Daniel Golem an the term encompasses has following
five characteristics and abilities:munotes.in

1)Self-Awareness : Knowing your emotions, recognizing feelings
as they occur, and discriminating between them.
2)Mood Management : Handling feelings so they're relevant to the
current s ituation and you react appropriately.
3)Self-Motivation : Gathering up your feelings and directing
yourself towards a goal, despite self -doubt, inertia, and
impulsiveness.
4)Empathy : Recognizing feelings in others and tuning into their
verbal and nonverbal cu es.
5)Managing relationships : Handling interpersonal interaction,
conflict resolution, and negotiations.
Thus, emotional intelligence is not same as self -esteem and
optimism. Rather emotionally intelligent people are both social and
self-aware. Those scor ing high on managing emotions enjoy
higher -quality interactions with friends (Lopes et.al.2004). They
avoid being hijacked by overwhelming depression, anxiety or
anger. Being sensitive to emotional cues, they know what to say to
soothe a grieving friend, e ncourage a colleague and manage
conflict.
Emotional intelligence is less a matter of conscious efforts
and more of one’s unconscious processing of emotional
information. ( Fiori,2009) . Across many studies in many countries,
those scoring high on emotiona l intelligence showed somewhat
better job performance. They could also delay gratification in
pursuit of long -term rewards, rather than being overtaken by
immediate impulses. They were emotionally in tune with others and
therefore often succeeded in career ,m a r r i a g ea n dp a r e n t i n g .
3.1.4Is intelligence neurologically Measurable?
Using today’s neuroscience tools, we might link differences
in people’s intelligence test performance to dissimilarities in the
heart of smarts —the brain? Might we anticipate a fu ture brain test
of intelligence?
More recent studies that directly measure brain volume
using MRI scans do reveal correlations of about +.33 between brain
size (adjusted for body size) and intelligence score (Carey, 2007;
McDaniel, 2005). Moreover, as adu lt’s age, brain size and
nonverbal intelligence test scores fall in concert (Bigler et al., 1995).
One review of 37 brain -imaging studies revealed associations
between intelligence and brain size and activity in specific areas,
especially within the fronta l and parietal lobes (Jung & Haier, 2007).
Sandra Witelson would not have been surprised. With the brains ofmunotes.in

Page 45

45
91 Canadians as a comparison base, Witelson and her colleagues
(1999) seized an opportunity to study Einstein’s brain. Although not
notably heavier or larger in total size than the typical Canadian’s
brain, Einstein’s brain was 15 percent larger in the parietal lobe’s
lower region —which just happens to be a center for processing
mathematical and spatial information. Certain other areas were a
tad sma ller than average. With different mental functions competing
for the brain’s real estate, these observations may offer a clue to
why Einstein, like some other great physicists such as Richard
Feynman and Edward Teller, was slow in learning to talk (Pinker,
1999).
If intelligence does modestly correlate with brain size, the
cause could be differing genes, nutrition, environmental stimulation,
some combination of these, or perhaps something else. Recall from
earlier chapters that experience alters the brain. Rats raised in a
stimulating rather than deprived environment develop thicker,
heavier cortexes. And learning leaves detectable traces in the
brain’s neural connections. “Intelligence is due to the development
of neural connections in response to the envi ronment,” notes
University of Sydney psychologist Dennis Garlick (2003).
Postmortem brain analyses reveal that highly educated people die
with more synapses —17 percent more in one study —than their
less-educated counterparts (Orlovskaya et al., 1999). This does not
tell us whether people grow synapses with education, or people
with more synapses seek more education, or both. But other
evidence suggests that highly intelligent people differ in their neural
plasticity —their ability during childhood and adolesc ence to adapt
and grow neural connections in responseto their environment
(Garlick, 2002, 2003).
The neurological approach to understanding is currently in
its heyday. Will this new research reduce what we now call the g
factor to simple measures of under lying brain activity? Or are these
efforts totally wrongheaded because what we call intelligence is not
a single general trait but several culturally adaptive skills? The
controversies surrounding the nature of intelligence are a long way
from resolution.
3.2 ASSESSING INTELLIGENCE
3.2.1The origins of intelligence testing:
In 1904, French government officials asked psychologist
Alfred Binet to help them decide which students were most likely to
experience difficulty in school, since they needed a way t oi d e n t i f y
and help these youngsters. (Primary school education was
mandatory in France). Binet asked a colleague, Theodore Simon,
to help him create a test with questions focusing on practicalmunotes.in

Page 46

46
matters such as attention, memory and problem solving, things the
children were not taught in school. Some children were able to
answer more advanced questions than their age group, and so,
based on these observations, the now classical concept of mental
age came into being. Their test, the Binet -Simon scale, was t he
first standardized IQ test.
By 1916, Stanford University psychologist Lewis Terman had
taken the Binet -Simon scale and adapted it to the American public.
The Binet –Simon Scale (adapted) was named the Stanford -Binet
Intelligence Scale and soon became t he standard intelligence test
for several decades in the United States. The Stanford -Binet, as it
is called, used a single number known as IQ (Intelligence Quotient)
to represent an individual’s score on the test.
During World War I, several tests were de veloped by the
United States Army with an eye to screening recruits and
determining eligibility for certain military jobs. The Army Alpha was
a written test and the Army Beta was administered only in cases
where the recruits were illiterate.
These and ot her IQ tests were eventually used for a less
than admirable purpose, screening new immigrants as they entered
the United States from Ellis Island. IQ test results were
inappropriately used to make sweeping generalizations and to
verify the claim of “surpri singly low intelligence” of Jewish and
Southern European immigrants. These test results and outlandish
claims led to a then popular proposal by the “racially motivated”
psychologist H.H. Goddard and others (1920) —to enable Congress
to enact restrictions in immigration. Despite the fact that the tests
administered were in English only and the vast majority of the
immigrants could not understand that language, the United States
government deported many thousands of worthy individuals whom
they unfortunately l abeled as “unfit” or “undesirable.” And this took
place a full decade or so before the news began to trickle in from
Nazi Germany about Adolph Hitler’s new eugenics. This is, indeed,
a sad chapter in the history of the United States of America.
In 1955, the Wechsler Adult Intelligence Scale made its
debut. The WAIS, as it is called, was psychologist Robert
Wechsler’s first test, and the WISC (Wechsler Intelligence Scale for
Children) and the Wechsler Preschool Primary Intelligence Scale of
Intelligence (W PPSI) were developed later. The adult version has
since gone through three revisions: WAIS -R (Revised, 1981), the
WAIS -III (1997), and, in 2008, the WAIS –IV made its first
appearance in the United States. Thus, psychologist started to
develop psychologic al tests scientifically.munotes.in

Page 47

Measurement of intelligence is a topic that has interested
psychologists since last more than 100 years. It was Alfred Binet
and his team in France who developed some of the earliest tools
for measuring Intelligence. Let us unders tand the concept of
Intelligent Quotient (IQ).
Intelligent Quotient (IQ):
The concept of IQ was for the first time introduced by William
Stern in 1912 and employed in 1916 Stanford Binet Scale. IQ is a
ratio concept and is a classic score of intelligence obtained by
dividing chronological age by mental age and multiplying by 100.
Intelligent Quotient (IQ) =M e n t a lA g e/
Chronological Age* 100
Originally, IQ was calculated with the formula A 10 -year-old
who scored as high as the average 13 -year-old, for exa mple, would
have an IQ of 130 (13/10 X 100). With the help of IQ, children of
different chronological ages can be directly compared. IQs that are
over 100 indicate that the person is more intelligent than the
average.
3.2.2Modern Tests of Mental Abilitie s:
There are many different ability tests developed in the world
of psychology. We would discuss only some of these test such as
Binet’s mental ability test, Stanford -Binet test and The Wechsler
test.
1.Binet’s Mental Ability Test:
Alfred Binet along with his colleague Theodore Simon
developed one of the first known Intelligence test, which came to be
called as Binet -Simon scale. This test was revised in 1908 and
191. Binet believed that intelligence should be measured by tasks
that required reasoni ng and problem solving. According to Binet the
slow learner child was similar to a normal child except for the fact
that the mental growth of the slow child was retarded. On the test of
intelligence, a slow learner would perform just like a normal child
but his/her performance will be equivalent to that of a young child.
He developed the concept of mental age. Alfred Binet assumed that
intellectual abilities improved with age during childhood. Alfred
Binet arranged the test items of his intelligence tests i no r d e ro f
increasing difficulty. The score obtained on Binet’s Intelligence Test
is equal to the number of questions answered correctly, but it is
expressed in terms of the age of the child for which that score is the
average. For e.g. if the child correc tly answered 9 items and the
average number of items answered by the children 4 years and 3
months in age was 9 then the score would be expressed as “4
years and 3 months.” Binet called this score as the mental age.munotes.in

Page 48

2.Stanford -Binet Test:
The Stanfor d–Binet Intelligence Scales is an individually
administered intelligence test that was revised from the original
Binet -Simon Scale by Lewis M. Terman, a psychologist at Stanford
University. After Binet’s death in 1911 his tests were revised and
used extens ively in America. The most widely used revision was
called as Stanford -Binet tests. One of the first Stanford Binet Scale
was developed in 1916. This test was revised in 1937 1960, 1972
and 1986 and 2003. The Fifth edition of Stanford -Binet, revised in
2003, (SB5) is the most updated and revised version of the
Stanford -Binet tests. The Stanford Binet Scale is one of the most
widely used and scientifically well developed tests of Intelligence to
measure the intelligence of school children.
3.The Wechsler Tests:
The Wechsler intelligence scales were developed by Dr.
David Wechsler, a clinical psychologist with Bellevue Hospital.
David Wechsler developed a series of test initially to measure adult
intelligence and later on he developed tests of intelligence to
measure intelligence of children and preprimary school children.
His tests have been periodically revised and updated. David
Wechsler felt that the Binet scales were too verbally loaded for use
with adults, so he designed an instrument with sub -tests t o
measure both verbal and nonverbal abilities, largely borrowing from
many other tests, such as the US Army Alpha test.
The first Wechsler scale, called as the Wechsler Bellevue
scale was constructed in the year 1939 to measure adult
intelligence. However , this scale had a number of technical
difficulties, which were corrected in the 1955 scale, which has
become famous as WAIS. The 1955 WAIS was revised in 1981 and
is called as WAIS -R. He further revised this test which is today
called as WAIS –IV. He has also developed Wechsler Intelligence
Scale for Children (WISC –IV) and the Wechsler Preschool and
Primary Scale of Intelligence (WPPSI –III).
These tests differ from that of Stanford -Binet in the sense
that they give three different types of IQ: Verba l Scale IQ,
Performance Scale IQ and Full Scale IQ. All of the Wechslerscales
are divided into six verbal and five performance subtests. The
following table gives a brief overview of the different types of sub -
tests in the WAIS test.munotes.in

3.2.3Principles of Test Construction:
Test const ruction is a scientific process and is concerned
with development of new tests, revising existing tests and issues
relating to test administration and interpretation. Development of
intelligence test is a difficult process. Some important
characteristics o f good test construction include: Reliability, Validity,
Standardization of Tests and Norms.
Reliability:
Reliability is one of the most important characteristics of a
given scientific test. Reliability can be defined as the extent to
which a test yield s consistent results. Reliability refers to
consistency of scores obtained by the same individual on the same
test or equivalent forms of the test, which is administered after
some period of time. It refers to the scores obtained by the same
person when re -examined with the same test on different occasions
or with different sets of equivalent form. In order to determine
reliability we actually measure correlations between two sets of
scores on the same test (also called as test retest reliability)
obtained by the same individual after some period of time. If instead
of the same test an equivalent form is used then the reliability is
termed as equivalent or alternate form of reliability. When two
examiners obtain score by administering the same test to an
individual then the correlation between the scores obtained by the
two examiners is called as scorer reliability or inter -rater agreement
or inter -judge reliability.
Validity:
Validity is an important characteristic of intelligence test. It
means the exten t to which a test measures what it is supposed to
measure. Validity is concerned with the following question: Does a
test measure what it wants to measure and how well it measures
what it wants to measure. Validity of a test is generally assessed by
correl ating it with some external criteria. This criterion can be
obtained either along with the test score or just prior or immediately
after the test score was obtained. Thus, validity of a given test is
determined by correlating the scores obtained by the ind ividual on a
test as well as scores obtained on some external criteria.munotes.in

Page 50

Standardization of Tests:
The number of questions you answer correctly on an
intelligence test would tell us almost nothing. To evaluate your
performance, we need a basis for compari ng it with others’
performance. To enable meaningful comparisons, test -makers first
give the test to a representative sample of people. When you later
take the test following the same procedures, your scores can be
compared with the sample’s scores to dete rmine your position
relative to others. This process of defining meaningful scores
relative to a pretested group is called standardization.
Standardization is basically concerned with uniformity. By a
standardized test we mean a test which is uniform and w ill remain
uniform for all the conditions and subjects. Uniformity should be in
the areas of administering, scoring and interpretation of a test.
Norms:
Norms are the scores from the standardization group. Norms
are standards (created by the scores of a large group of individuals)
used as the basis of comparison for scores on a test. Norms are
developed on the basis of empirical data by using a sample (called
as normative sample). Norms tell us what is a good or of poor
performance. Norms help us to set s tandards against which we
judge an individual’s performance on a given test.

4.1INTRODUCTION
In this unit, we will discuss about motivation. Before
explaining the con cept of motivation, let’s ask you some questions
that will help you to understand the concept of motivation.
Have you ever wondered why some people regularly go to
gym or take part in Marathon even if they are senior citizens or
have physical disability? In fact, such people might have been
discouraged by their family members. They do not expect to
receive any reward or recognition and yet take part with greatmunotes.in

Page 53

53enthusiasm. Similarly, the question arises why do people observe
fast or go on pilgrimage even th ough it causes lot of physical
discomfort? Why do some people enjoy activities like hiking,
playing football while others like to sit down in a corner, with a novel
or watch a movie on television?
We can continue raising question “Why” for almost each and
every situation in everyday life. By raising the question “why” we
are trying to understand the reason or motivation behind the
behavior that we observe.
Different people may have different motives for same behavior .
For example, a student may take up a course in Psychology
because he likes the subject and wants to enhance his knowledge,
while another may take up a course in Psychology because this
may brighten his career prospects, a third student may take up a
course in Psychology because his parents h as insisted on it or
because of peer pressure.
Different people with same motive may behave in different
manner . For example, a person who is hungry may decide to have
his lunch to satisfy his hunger while another person may satisfy his
hunger by eating ab u r g e ro ra n yo t h e rj u n kf o o d .
The motivation issue becomes more complex with the fact
that the same person showing same behavior may have
different motives at different stages of life. For example, a lady
who dislikes mathematics, may study mathematic s to pass her
school exam, but later on, she may study mathematics again with
lot of zeal to help her child to cope up with this subject.
These examples highlight the fact that all human behavior
takes place in response to some form of internal or exter nal
motives /needs or desires. It also shows that motivation is a
complex issue and yet necessary to understand so that we can
deal with them in much more meaningful and effective way. Now let
us try to understand what is motivation.
Definition of Motiva tion:
The word motivation comes from a Latin word ‘movere’
which means to move or to energize. Steers and Porter (1987)
believe that “When we discuss motivation, we are primarily
concerned with (1) what energizes human behavior; (2) what
directs or channe ls such behavior and (3) how this behavior is
maintained or sustained.”munotes.in

Page 54

54Thus, in another way motivation can be defined as an
internal state or condition that activates and gives direction to
our thoughts, feelings and actions, and maintains our activity
till our goal is achieved.
Characteristics of Motivation:
On the basis of above mentioned definitions and explanation
we can deduce following characteristics of motivation.
1.Motivation is Inferential: An important characteristic of
motivation is that we cannot see it directly. We can only infer it to
explain others’ behavior. For example, we cannot see hunger, but if
we see a person eating food hungrily, we can infer that his behavior
is guided by hunger motivation.
2.Motivation Predicts Behaviour: Motivat ion helps us to make
predictions about our own or others’ behavior. If we understand the
motive behind a person’s present behavior, we might be in a better
position to predict how that person will behave in future.
3.Motivation is goal directed behavior: Motivated individuals
keep working until they reach their goal.
4.Multiple motives -People can have multiple causes for same
behavior. For example, a person may take part in adventure sport
due to need to risk taking motive, social motivation, escape from
boredom, need to overcome fears, need for achievement, etc.
5.Motivation varies in the type and strength –People differ in
the type and strength of their motives from time to time. Studies
have shown that there are two types of motivation that can
influenc e a person. Primary motives and Secondary Motives.
Primary motives cater to our need for self -preservation. For
example, need for hunger, thirst, warmth, avoidance of pain, etc.
Secondary motives are mainly learned motives, and they differ from
one person to another. In many ways, they involve a person's own
sense of values and priorities in life. Secondary motivation is
influenced by socio -cultural factors.
6.A person may be aware of his motives or may not be aware
of his motives that guide his behavior. Usually a person may
automatically respond to primary motives without being conscious
of them and may be fully aware of his secondary motives and
meticulously plan to achieve them.munotes.in

Page 55

554.2 MOTIVATIONAL CONCEPTS
The question, why people behave as they do, has intrigued
psychologists for more than a century and has generated lot of
research. There is no single answer. Motivation can be triggered by
biological, cognitive and social factors. Mayer (2013) aptly
suggested that motivation arises from the interpl ay between nature
(the bodily “push”) and nurture (the “pull” from our thought
processes and culture). However, the complexity of motivation has
led different psychologists to develop various conceptual
approaches or theories of motivation over the years. Many of these
theories of motivation differ in the amount of emphasis they place
on either biological, cognitive or social factors but most of them
include some level of both (some nature, some nurture).
We will elaborate here on four most prominent theori es that have
received lot of attention over the years.
Theories of Motivation
4.2.1 Instincts and Evolutionary Theories:
Instincts refer to inborn patterns of behavior that are
biologically determined, have a fixed pattern throughout a species,
and are not learned behaviors. Early in the 20thcentury,
psychologists were highly influenced by Charles Darwin’s
evolutionary theory and sought to explain the motivation behind all
kinds of behavior in terms of instincts. For example, if people
criticized thems elves, they explained it in terms of “self -abasement
instinct”.
Instinct theory argued that people try to survive, and that any
quality that increases survival will eventually become genetically
based. Psychologists believed that people and animals are bo rn
with preprogrammed set of behaviors that are necessary for their
survival. These instincts give them the energy that channels their
behavior in appropriate direction. For example, sex can be
explained as a response to an instinct for reproduction.
William McDougal (1908) viewed instincts as behavior patterns
that are unlearned, uniform in expression and universal in a
species. For example, within a species of bird, all the members
may build identical nests and work in the same ways. This is true
even fo r those birds of that species born and raised in captivity and
isolation, and thus could not have learned the appropriate nest
building behavior from other, experienced role model birds.
McDougal carried it a step further by stating that humans are the
same and have instincts for behaviors such as: parenting,
submission, jealousy, mating, and more.munotes.in

Page 56

56Criticism of this perspective:
1.Instead of explaining human behavior, this theory was simply
naming them or labeling them in terms of instincts. For example,
submissive people possess the instinct of submission. To name a
behavior is not same as explaining it.
2.According to it all instincts occur impulsively and therefore
people have no control over their behavior. It does not recognize
the role of free will.
3.There is a circular argument. The cause (instinct) explains the
behavior, but the behavior is proof for its cause.
4.There is no agreement on what, or even how many primary
instincts are there. William McDougall (1908) suggested that there
are 18 instincts. Other theorists came up with even more. One
sociologist scanned 500 books and compiled a list of 5759
supposed to be human instincts.
4.2.2 Drives and Incentives:
After rejecting instinct theory, psychologists proposed drive -
reduction theory .L e tu s first understand what is the meaning of
drive.
Drive:
A Drive is an internal state of tension/ an unpleasant state
that causes us /energizes behavior to do something to reduce or
remove that tension. A drive is an arousal that in order to fulfill
some need. For example, biological needs arising within our bodies
create unpleasant states of arousal –the feelings of hunger, thirst,
fatigue, etc. The moment this drive/ arousal or tension takes place,
we become active to reduce it or eliminate it.
So, the physiological aim of drive reduction is homeostasis.
Homeostasis is the body’s natural tendency to maintain a steady
internal state -a state of physiological equilibrium. For example, our
body’s temperature regulation works like a room thermostat. I fo u r
body’s temperature cools, blood vessels constrict to conserve
warmth, and we feel driven to put on more clothes or seek a
warmer environment. On the other hand, if the body temperature
increases, we start perspiring to cool the body and seek to remov e
extra clothing and seek cooler environment, which finally leads to
the restoration of equilibrium.
Basic kinds of drives, such as hunger, thirst, sleepiness,
stable body temperature, etc. are called Primary drives . According
to drive theory, motivatio n is basically a process in which these
primary drives push (drive) us to action designed to satisfy these
needs. Behaviors that helps us to reduce the appropriate drive aremunotes.in

Page 57

57strengthened and tend to be repeated and those behavior that fail
to bring the equ ilibrium /homeostasis will not be repeated when that
drive occurs once again.
Criticism:
1.Drive reduction theory works well to explain the actions people
take to reduce tension created by needs, but it does not explain all
human motivation. For example, i td o e sn o te x p l a i nw h yw ee a t
even when they are not hungry?
2.It could not explain behavior in which the goal is not to reduce a
drive, but rather to maintain or even to increase a particular level of
arousal. For example, some people seek thrills through activities
such as racing cars, etc. The question arises why would people do
things like these if it does not reduce some need or restore
homeostasis? In such cases the concept of homeostasis seems
irrelevant.
3.Though, in its original form, drive theory f ocused primarily on
biological needs and the drives they produce. But later on,
psychologists realized that motivation may exist without a drive
/arousal and therefore extended this model to cover other forms of
behavior that was not clearly linked to basi c needs, such as drive
for stimulation, status, achievement, power, and forming stable
social relationships. These are called secondary drives .T h e
needs involved in secondary drives are created by prior experience
and learning.
Psychologists recogniz ed the fact that we are not only
pushed by our need to reduce drive, but we are also pulled by
incentives.
Incentives:
Incentives are positive or negative stimuli that attract or repel
us. Incentives are influenced by an individual’s personal
experience s or learning in the past. Here we can see a move away
from biological influence toward the environment and its influence
on behavior. In incentive approach, behavior is explained in terms
of external stimulus and its rewarding or repelling properties. The
rewarding or repelling properties exist independently of any need or
level of arousal and can cause people to act only upon the
incentive. Thus incentive theory is actually based on the principle of
learning.
For example, if in the past, a person has enjoyed the taste
and aroma of freshly made coffee, then while passing outside a
coffee shop, the aroma of freshly made coffee can motivate his
behavior and he may get pulled (attracted/tempted) towards the
coffee shop. When there is both a need and an inc entive, we feelmunotes.in

Page 58

58strongly driven. For instance, if you are hungry and you get the
aroma of freshly baked bread, you will feel strong hunger drive. The
aroma of baking bread becomes a compelling incentive. So, for
each motive, we can ask, “How is it pushed b yo u ri n b o r n
physiological needs and pulled by incentives in the environment?”
In other words, drive reduction theory accepted that our past
learning and environment also plays a major role along with
physical internal drives in motivating our behavior.
4.2.3 Optimum Arousal:
With more research in the area of motivation, when it
became clear to psychologists that we are much more than
homeostasis system and people sometimes seek to increase rather
than reduce existing drives, another theory of motivation known as
“arousal theory” was proposed. This theory focuses on arousal, our
general level of activation. After all our biological needs are
satisfied, we feel driven to experience stimulation and we hunger
for information. Neuroscientists, Irving Biederma na n dE d w a r d
Vessel (2006) said we are “infovores”, after they identified brain
mechanism that rewards us for gaining information. For example,
toddlers explore every nook and corner of the house, children love
to break their toys to investigate the mechan ism inside the toys,
people love to travel to new places just to explore what those
places look like, etc.
Arousal levels vary throughout the day, from low levels
during sleep to much higher levels when we are performing
strenuous tasks or activities t hat we find exciting. The theory
suggests that what we seek is not less or more arousal but optimal
level of arousal –the level that is best suited to our personal
characteristics and to whatever activity we are currently
performing. If our stimulation an d activity levels become too high,
it creates stress for us and we try to reduce them. On the other
hand, if the levels of stimulation and activity are too low, we feel
bored and try to reduce boredom by seeking stimulation and
activity. Even though the av erage person might require an average
level of arousal to feel content, there are some people who need
less arousal and some who need more. The person who needs
more arousal is called a sensation seeks. Sensation seekers seem
to need more complex and varie d sensory experiences than do
other people.
4.2.4 Maslow’s Need Hierarchy:
Abraham Maslow proposed that human beings are driven by
different factors/needs at different times. When a single need is
fulfilled humans seek to satisfy the next need, and so forth. Maslow
introduced his theory based on personal judgment and his theory is
generally known as the need hierarchy theory. He believed that if
people grow up in an environment in which their needs are not met,munotes.in

Page 59

59they will be unlikely to function as healt hy individuals or well -
adjusted individuals.
Maslow believed that all needs vary in priority. Some needs
have to be satisfied first while the satisfaction of other needs can be
delayed. He described these priorities as a hierarchy of needs and
arranged them in a pyramidal form to indicate which needs have
more priority. The journey of satisfying these needs before
graduating to other needs starts from the bottom of the pyramid.
Originally Maslow’s (1943,1954) hierarchy of needs pyramid
had only five needs –up to self -actualization, but later on it was
expanded to include cognitive and aesthetic needs (Maslow,
1970a) and later transcendence needs (Maslow, 1970b). Maslow
explained that throughout our life we are dominated by some need
or the other. Th ere is not a single moment in our daily life when we
are not dominated by some need or the other. Now let us see what
these needs are.
1.Physiological Needs -These needs include the need for food,
water, rest, air, temperature regulation, etc. If these ne eds are not
met, the organism can’t survive. Thus, these are the most basic
and most important needs. Maslow classified these needs as part
of deficiency needs. If these needs are not satisfied, the human
body cannot function properly and will ultimately f ail. Therefore,
once any of these needs is aroused it demands immediate
gratification without any delay and a person cannot think of
anything else unless and until that particular need is satisfied.
2.Safety Need –Once the physiological needs are satisfied, then
we get concerned about our safety. These needs refer more to the
long-term survival than day to day needs. In other words, we are
faced with the question that just as today we have been able to
satisfy our physiological needs and survived peacefully, can we
survive in future also.
a.People want physical safety –freedom from threat of war,
natural disaster, family violence, childhood abuse. They want order
and do not want to live in a world that is not filled with chaos and
danger.
b.People want econom ic safety -For example, all saving
schemes, insurance schemes work on the basis of this need only.
We choose jobs where we can have job security; we try to improve
our qualifications today to ensure that our future is not endangered.
We fix safety doors, grills, and cc cameras in our homes, offices to
satisfy this need only. People seek out grievance procedures for
protecting themselves from unilateral authority and arbitrary
decisions.munotes.in

Page 60

603.Belongingness and love –Once our safety need is
satisfied ,then we pay attention to other people in our surroundings.
People seek out love and affection from family members, friends,
and lovers. People long to get into steady long term relationships. It
is the need to be loved and to love, to belong and be accepted;
need to avoid loneliness and separation.
4.Esteem -Once individuals’ physical, safety and belongingness
needs are satisfied, they look at ways to satisfy their need for
developing positive feelings of self -worth and self -esteem, and act
to foster pride in their w ork and in themselves as people. At this
level, people are concerned with achievements, mastery,
independence, status, dominance, prestige, responsibilities, etc.
both at work place as well as in their social circle.
5.Cognitive -Needs at this level are b ased on acquiring
knowledge and understanding of the world, people, behavior, etc. If
you are in college to learn (not simply to get a degree) then you are
attempting to fulfill your cognitive needs. This need also includes
curiosity, exploration, need for meaning and predictability. This
need is typical of an academician who learns for the sake of
gathering knowledge.
6.Aesthetic -Aesthetic need includes appreciation and search for
beauty, balance and order in life. Humans need beautiful imagery
or somethi ng new and aesthetically pleasing to continue up towards
Self-Actualization. Aesthetics refers to the quality of being
creatively, beautifully, or artistically pleasing; aesthetic needs are
the needs to express oneself in pleasing ways. Decorating your
living room, wrapping birthday presents attractively, washing and
waxing your car, and keeping up with the latest styles in clothing
are all ways of expressing your aesthetic sense. This need is
typical of artistic people.
7.Self-actualization -The growth of self-actualization refers to
the need for personal growth and discovery that is present
throughout a person’s life. In self -actualization, a person comes to
find a meaning to life that is important to them. As each individual is
unique the motivation for self-actualization is satisfied in different
ways by different people. For example, people can achieve self -
actualization through creating works of art or literature, through
sport, in the classroom, or within a corporate setting. This is the
highest and m ost difficult level to reach. In fact, according to
Maslow, very few people actually reach this level. Self -actualization
is the need to fulfill one’s own potential, capacities and talents. As
Maslow stated, “What a man can be, he must be.”
According t o Maslow self -actualizing persons have some
common characteristics such as they are -able to look at lifemunotes.in

Page 61

61objectively, problem -centered (not self -centered) .T h e ya r e
independent and nonconformist. They are democratic, fair and non -
discriminating, c oncerne df o rt h ew e l f a r eo fh u m a n i t y ,a ccept
themselves and others as they are and do not trying to change
people. They have deep appreciation of basic life -experiences,
establish deep satisfying interpersonal relationships with a few
close intimate friends rathe r than many surface relationships. They
have unusual sense of humour directed at oneself or the human
conditions in general. They are spontaneous, creative, inventive
and original, excited and interested in everything, and have strong
moral values.
8.Trans cendence Needs: Maslow later divided the top of the
triangle to add self -transcendence which is also sometimes referred
to as spiritual needs. Spiritual Needs are a little different from other
needs, accessible from many levels. This need when fulfilled, l eads
tofeelings of integrity and take things to another level of being.
Transcendence involves helping others to achieve their full
potential.
Criticism of the theory:
1.There is little scientific support for this theory. Maslow
developed this theory bas ed on his personal observations rather
than on any empirical research.
2.There have been many anecdotal evidences indicating that
lower needs need not be satisfied before moving over to higher
needs. For example, while preparing for an upcoming exam, a
student may not eat / sleep a day before exam.
3.Maslow’s theory is based on his study of Americans. Cross -
cultural research shows that the order of needs in the hierarchy
does not always hold true in other cultures.

624.3HUNGER
Introduction: Hunger as a Motive
Hunger motivation –an urge to eat food is one of the most
powerful biological motivation. The power of hunger motivation wa s
very aptly demonstrated by Aneel Keys et.al. (1950) in their
experiment. In their experiment, 36 male volunteers went through
semi starvation and researchers studied their behavior. Semi -
starvation had physical and psychological impact on these men.
With out thinking about it, they began conserving their energy;
appeared listless and apathetic. They became food obsessed. They
talked, day dreamed about food, collected recipes, read cookbooks,
and stared at forbidden food. In other words, unsatisfied hunger
motivation hijacked their consciousness.
Hunger motivation and eating habits of people today have
become a major concern and has been extensively studied. The
question arises why do we feel hungry? Research has shown that
hunger is a much more complex ph enomenon and there are
various aspects to it.
4.3.1 Physiological Components of Hunger:
Generally, we know that hunger takes place due to empty
stomach. But this is not the only cause. There are other causes
also that activate hunger.
a)Hunger Pangs/ Sto mach Contraction: In an earlier
experiment, Canon(1912) believed that the source of the hunger
motivation was hunger pangs or stomach contractions. When the
stomach is empty, contractions occur and are sensed and they are
the signals for feelings of hunge r. Canon believed that the presence
of food in the stomach would stop the contractions and appease the
hunger drive. But it was found that in many cases, empty stomach
is not the only deciding factor. Recent research studied showed
that people reported fee ling hungry and ate food even after their
stomach was removed.
b)Body Chemistry and the Brain: Human beings and other
animals automatically regulate their caloric intake to prevent energy
deficits and to maintain a stable body weight. Body does this
automat ic regulation of calories intake through ‘Glucose’ or ‘Blood
sugar’ . Pancreas in our body produce hormones called insulin
and glucagon that control the levels of fats, proteins and
carbohydrates in the whole body, including blood sugar. Insulin
reduces the level of glucose in the blood stream while glucagons
increase the level blood glucose levels. When glucose drops below
a certain level, our brain triggers the feeling of hunger and people
eat. When the glucose level in the blood exceeds a certain point,munotes.in

Page 63

63they feel satiated and stop eating. If your blood glucose level drops,
you may not consciously feel this change. But your brain, which is
automatically monitoring your body’s internal state, will trigger
hunger. This is the reason why dieticians ask a perso n to take low -
carbohydrate diet. Low carbohydrate will control the insulin reaction
and prevent hunger cravings.
c)Hypothalamus: Brain receives the messages from stomach,
intestine and liver about glucose level in body and accordingly
triggers hunger. Howe ver, stomach and pancreas are not the only
factors influencing our hunger. The hypothalamus in our brain also
plays a significant role in controlling the hunger. The hypothalamus
has two parts that control our eating behavior. These two parts are –
1.The Ven tromedial Hypothalamus (VMH)
2.The Lateral Hypothalamus (LH).
1.The ventromedial hypothalamus (VMH) is involved in
stopping the eating response when glucose levels in the blood
go up . For example, in one experiment, rats whose VMH areas
were damaged could not stop eating. The kept eating until they
were quite overweight (looked almost like a football).
2.The Lateral Hypothalamus (LH) influences the onset of eating
behavior when insulin levels go up in the blood .I ft h i sa r e ao f
hypothalamus is damaged, rats st op eating to the point of
starvation. They would eat only when they are force fed. Blood
vessels connect the hypothalamus to the rest of the body, so it can
respond to our current blood chemistry and other incoming
information. One of its task is to monito rt h el e v e l so fa p p e t i t e
hormone such as ghrelin, a hunger arousing hormone secreted by
an empty stomach. During bypass surgery for severe obesity,
doctors seal off part of the stomach. The remaining stomach then
produces less ghrelin, and the person’s app etite lessens. Other
appetite hormones are leptin, PYY and orexin. Orexin triggers
hunger while the other two reduce hunger.
Weight Set Point and Basal Metabolic Rate:
Hypothalamus affects the particular level of weight that the
body tries to maintain. Th is is called weight set point. When semi
starved rats fall below their normal weight, the weight thermostat
(that is complex interaction between appetite hormones and brain
activity) signals the body to restore the lost weight. Hunger
increases and energy expenditure decreases. If body weight rises,
as it happened when rats were force fed, hunger decreases and
energy expenditure increases. This stable weight toward which
semi starved and overstuffed rats return is their weight set point.
Metabolism –therate at which the body burns available energy for
maintaining basic body functions when the body is at rest. Whenmunotes.in

Page 64

64people don’t get enough food for a long time, to maintain their set
point, they reduce their energy expenditure, partly through inactivity
and partly by dropping basal metabolic rate. Metabolism and
exercise also play a part in the weight set point.
Some researchers, however, doubt that our bodies have a
preset tendency to maintain optimum weight. They point out that
slow, sustained changes in body weight can change one’s set point
and that psychological factors also influence our feeling of hunger.
With unlimited access to a wide variety of food, people as well as
animals, tend to overeat and gain weight. Therefore, researchers
have given up on the idea of biologically fixed set point and now
they prefer the term settling point. Settling point indicates the level
at which a person’s weight settles down in response to caloric
intake and expenditure, which is influenced by biology and
environme nt both.
The rate at which the body burns energy when a person is
resting is called the basal metabolic rate (BMR) and is directly tied
to the set point. If a person’s BMR decreases, that person’s weight
set point increases. The BMR decreases more dramat ically as the
age of the person increases. Adolescents can eat far more than an
adult of the same size and not gain weight. In adulthood, the BMR
begins to decline. If the eating habits of the teenage years are
maintained, adult will gain excessive weight in no time.
4.3.2. The Psychology of Hunger:
The question arises is hunger controlled and regulated by
biological factors only or whether psychological, cultural and
situational factors can also influence the feeling of hunger and
eating behavior? The an swer is, along with biological factors, all
these factors mentioned above also play a very significant role in
driving and regulating the feeling of hunger.
A) Eating is a learned Behavior:
People often eat even when they are not hungry. Many of
them ea t breakfast, lunch and dinner at certain times just because it
is the convention, that is, it is lunch/dinner time. A large part of this
convention is result of our classical conditioning. The body
becomes conditioned to respond with the hunger reflex at c ertain
times of the day, through association with the act of eating at those
times of the day. For example, a person who has just had late
breakfast will still feel hungry at noon, simply because the clock
says it’s time to eat.
B) Memory:
Cognitive fact ors too play a part in eating behavior. For
example, Rozin et.al.(1998) conducted an experiment to show that
apart from internal cues from 9our bodies, memories about whenmunotes.in

Page 65

65we last ate can influence whether we decide to eat and how much
we eat at a given ti me. For their experiment, they tested two
patients with amnesia, who could not remember recent events -
events occurring more than a minute ago. Both patients were
offered lunch at lunch time and after 20 minutes they were again
offered lunch, which they readily consumed. 20 minutes after their
second lunch they were again offered lunch, a third time. One of
them ate part of the third meal also. They were asked to rate their
hunger before and after the meal. Both of them had rated their
hunger less after h aving first meal than before it. Yet, in spite of not
being hungry, they went ahead and had second meal and partly the
third meal also because they could not remember that they had just
eaten.
C) Taste Preference :
Very often, you must have noticed that a person enjoying
dinner at a wedding party comments that he has over eaten and
now he cannot consume another morsel, but while passing in front
of dessert counter he gets tempted by the sight of his favorite ice -
cream and gulps down a large helping of tha t ice -cream. The
reason is that b iological and cultural factors play a significant role in
our taste preference.
Biological Factors: It has been observed that people crave to
have starchy, high in carbohydrate food especially when they are
tense or depre ssed. Carbohydrates help boost levels of the
neurotransmitter serotonin, which has calming effects on our
nerves. Though preferences for sweet and salty taste are genetic
and universal but other taste preferences are conditioned. If people
are given highl y salted food from childhood, they develop a liking
for excess salt. Same is true for spicy food. People who become
sick due to food (food poisoning) develop an aversion to it and
avoid to eat that food in the future that caused them food poisoning.
Culture also affects the taste preference: Indian children are
used to eating spicy food and like it that way while European kids
are used to bland non -spicy food and can’t tolerate even the smell
of spicy curries from the neighborhood.
Taste preferences ar e adaptive. For example, the spices are
used in hot climate countries, especially in non -vegetarian dishes
because meat spoils quickly in hot climate and spices inhibit the
growth of bacteria. Pregnancy related nausea and food aversions
peak during the 10thweek of pregnancy because the developing
embryo is most vulnerable to toxins at that time.
Both human beings and animals avoid unfamiliar food,
especially animal based foods. Sociobiology explains that this
dislike of things unfamiliar was adoptive fo r our ancestors. Itmunotes.in

Page 66

66protected them from potentially harmful/toxic substances. So, there
is biological wisdom to our taste preference. Cultural trends can
also influence the human genetics that affect their diet and taste.
For example, where milk is availab le in abundance, survival
patterns have favored people with lactose tolerance.
D) Situational and Cultural Factors Influence Eating Behavior:
People eat more when they eat with others. This is the
reason why after participating in celebrations, we real ize that we
have over eaten.
Cultural factors also play a major role in determining what,
when, and how much we eat. Andrew Geier et.al. (2006) conducted
a research to show cultural influence on eating habits. They
observed that French people offer foods in smaller portion sizes.
That is why they are much slimmer than Americans. Their research
found that when people are offered large size portions, they
consume that entire large size portion and gain more calories. They
called this unit bias.
Food Varie ty:We tend to eat more when there is more variety of
food to choose from. From biological point of view, this tendency
makes sense. When food is available in plenty and in variety,
eating all types of food provides vitamins and minerals and produce
fat that used to protect our ancestors in winter or famine when food
was not available. But, now when food is available in abundance, if
a person wants to control his waistline, he needs to follow certain
rules as follows –
Before eating with others, they sho uld decide how much they
wish to eat
Make sure to take small size portions of the food
Not to go for second helpings.
Food should be served with smaller bowls, plates and utensils.
Variety should be limited and
Appealing food should be kept out of sigh t.

674.3.3 Obesity and Weight Control:
Being overweight and obesity is a growing problem all over
the world and it has taken the shape of an epidemic. In a survey
conducted in 2007 by World Health Organization, it was estimated
that worldwide more than one billion people are overweight and out
of that three million are obese -that is they had body mass index of
30 or more.
The question arises why being overweight is alarming for
us? If we look back at folk wisdom, in earlier centuries, being thin
was considered bad and unattractive while people used to find
heavier bodies attractive. Obesity was a symbol of affluence and
social status. It was believed that our bodies store fat for good
reasons. Fat is an ideal form of stored energy –a high calorie fu el
reserved to carry the body through periods when food is scarce.
Scarcity of food was a common occurrence in our prehistoric
ancestor’s time. So the convention was to consume when they
found energy rich fat or sugar. However, in present times, in most
parts of the world food is available in abundance and this
convention has now become dysfunctional.
A) Impact of being overweight or obese:
a)Biological: Being overweight has become a health hazard.
Studies have shown that obesity increases the risk of dia betes,
high blood pressure, heart disease, gallstones, arthritis and certain
types of cancer and shortens life expectancy.
b)Cognitive: Recent research has linked women’s obesity to their
risk of deteriorating cognitive abilities, including Alzheimer’s
disease and loss of brain tissues, in late life. Gunstad et.al. (2011)
found in their experiment that memory performance improved for
severely obese people, 12 weeks after they went through weight
loss surgery and lost significant weight.
c)Social: Obesity c an be socially toxic. It affects the way you are
treated by others and how you feel about yourself. The stereotype
of obese people is that they are lazy, slow, undisciplined, less
sincere, less friendly, meaner and extremely unpleasant.
Gortmakeret.al. (1 993) conducted a longitudinal study on
370 obese women and found that even after 7 years two third of
them were still obese and were earning less money than an equally
intelligent group of non -obese women and they were less likely to
get married. Similarly , Regina Pingitore et.al. (1994) studied the
impact of discrimination based on weight. They found that when the
same person appeared as overweight applicant he/she was
considered as less worthy of hiring than when he/she appeared as
normal weight person. W eight bias was especially strong against
women.munotes.in

Page 68

68Weight discrimination is worse than race and gender
discrimination. It occurs at every stage of employment. Overweight
people (especially women) have less chance of getting hired and
promoted, they are paid less and chances of their getting punished
for indiscipline and getting sacked from the job are much higher.
The prejudice against weight appears early in life. Children show
contempt and disdain towards fat children and even towards normal
weight friends of fat children. Obese children are bullied more.
d)Psychological Well -Being: Obesity is linked to lower
psychological well -being, especially among women. Obese women
are more likely to suffer depression, body dissatisfaction and low
self-esteem.
B) The Causes of Obesity:
1) Biological Factors:
I.Set Point and Metabolism: People become fat because they
consume more calories than they expend and to reduce weight
they go on diet. That means they reduce their food/ calorie
intake. In most of the cases dieting does not help. Why? This is
because once we become fat, we require less food to maintain
our weight than we did to attain it. Fat has a lower metabolic
rate than does muscles. That means fat takes less food energy
to maintain itself. So when an overweight person’s body drops
below its previous set point/settling point, the person’s hunger
increases and metabolism slows down. The body adapts to
starvation by burning off fewer calories. Bray (1969) reported
that in amonth -long experiment, obese patients’ dai ly food
intake was reduced from 3500 calories to 450 calories but they
lost only 6% of their weight. The reason was that their
metabolic rate dropped by 15% only as a result of starvation.
II.Physical Activity: In another experiment, Levine et.al. (1999)
overfed volunteers an extra 1000 calories a day for 8 weeks.
They found that those who tended to spend their extra calorie
energy by fidgeting more, gained least weight. Lean/slim
people have a natural tendency to move around much more
rather than sitting at one place for long time.
III.The Genetic Factors: Studies have shown than genes
influence body weight. For example, it was found that –
i.In a family, if two children are adopted , then in spite of
sharing same family meals, their body weights are not
simila r to each other and are not similar to their adoptive
parents also. Their body weightsare similar to their
biological parents’ body weight.munotes.in

Page 69

69ii.Another study reported that identical twins have closely
similar weights even when they are reared apart.
iii.It was al so found that if parents are obese then the
chances of a boy being obese are 3 times more and the
chances of girl being obese are 6 times more, compare to
children of normal weight parents.
iv.Scientists have identified many different genes that
influence bo dy weight. For instance, a variant of a gene
called FTO nearly doubles the risk of becoming obese.
IV.Hormonal Factors: Scientists now believe that a hormone
called leptin plays a key role in appetite control. Leptin is a
protein that is secreted as a hormo ne by the fatty tissues of
the body. Leptin enters the bloodstream from the fat cells,
traveling to the hypothalamus in the brain and causes the
hypothalamus to signal the body to either stop eating or to
eat more. When enough food is consumed, high levels of
leptin are produced that cause the appetite to decrease. A
low level of leptin signals a condition of starvation and
increases the urge to eat. Scientists conducted experiments
on obese rats by giving them a high dosage of leptin and
expected it to dec rease the appetite and result in weight loss
for the mice. However, it was found that certain obese mice
initially responded to leptin as it was expected but later on
did not lose weight when leptin levels were increased. They
developed a resistance to lep tin, suggesting that their bodies
can respond only to certain levels of leptin, and when the
level goes too high, the body stops responding, allowing
appetite to remain out of control. The studies are suggesting
that once we have gained a significant amoun to fw e i g h t ,o u r
sensitivity to leptin actually decreases.
2)Environmental Factors:
I.Sleep Loss: Studies in Europe, Japan and the United States
indicate that those who suffer from sleep loss tend to be obese
because with sleep deprivation, the levels of le ptin (which reports
body fat to the brain) fall, and ghrelin (the appetite -stimulating
stomach hormone) rises.
II.Social Influence: Social influence is another important factor in
gaining weight. A longitudinal study conducted over 32 years found
that peopl e are most likely to be obese when a friend becomes
obese. If the obese friend happens to be a close one, the chances
of your also becoming obese increase by three times.
III.The Food and Activity Factor: People from developed as well
as developing countries are getting heavier and obesity has
reached an alarming proportion. One of the most important reasonmunotes.in

Page 70

70for this phenomenon is our changing food consumption habits and
activity levels. We are eating more and moving less. Increasingly,
jobs requiring physical activity are declining and technology is
enabling us to do everything at the click of the button (remote
control). We have put fast food on every corner, junk food in our
schools, we have got rid of physical education classes, we put
chocolates and soft d rinks at the payment counters in malls and
every other shop. Junk food is available on every road and street,
in every nook and corner.
C)Weight Control:
With set point, metabolism and genetic and environmental
factors always working in favor of obesit y, it is not easy to lose
weight permanently. Many people lose weight successfully but it all
comes back with vengeance the moment they are not vigilant.
Psychologists believe that obesity is neither the result of any
personality maladjustment, nor it is due to lack of will power. In fact,
continuously trying to be thin puts people at the risk of binge eating,
food obsession, weight fluctuations, malnutrition, smoking,
depression, and harmful side effects of weight loss drugs. It is
better to accept onese lf as a bit heavy than to diet and binge and
feel continually out of control and guilty.
4.3.4 Close Up: Waist Management:
Researchers have offered some tips for managing your waist line.
1.Managing waist line requires being self -motivated and self -
disciplined. Permanent weight loss requires a lifelong change
in eating habits and increased exercise.
2.Minimize exposure to tempting food cues -keep tempting food
out of the house. Go for buying food items only when you have
eaten and your stomach is full. Avoid the counters where
sweets and chips or other fried items are kept.
3.Eat simple meals. If there is more variety, people consume
more.
4.Exercise empties fat cells, builds muscles, speeds up
metabolism and helps lower your settling point, especially
when supported by 7 to 8 hours of sleep a night.
5.Eat healthy food –Whole grain, fruits, vegetables and healthy
fats such as those found in olive oil and fish help regulate
appetite and artery clogging cholesterol.
6.Don’t starve all day and eat one big meal at night -It slows
down metabolism. Those who eat a balanced breakfast are by
late morning more alert and less fatigued.
7.Eat slowly that will lead to eating less. Don’t consciously
restrain your eating, drinking alcohol, and don’t feel anxious or
depressed about being overweight. This can trigger the urge to
eat.munotes.in

Page 71

718.Keep monitoring your eating, especially when you are eating
with your friends. One tends to eat more with friends. Once a
diet is broken, a person has a tendency to binge eat. So, make
sure a lapse should not become full collapse.
9.Connect to a support group -Join with others, either face to
face or online, with whom you can share your goals and
progress.
10.Don’t sit with any kind of food or drink while watching television
or a movie. Consciously unlea rn that behavior.
Check Your Progress:
1.Define Obesity. What is the impact of obesity and how waist
management can be done?
2.What are the causes of obesity.
3.Write a short note on waist management.
4.4 SUMMARY
You would recall that we have touched upon the three
learning items in this unit -Motivational, Hunger and Obesity.
In motivation, we have dwelled into definition and
characteristics of motivation, four theories of motivation -instinct
and evolutionary theory, drive -incentive theory, optimum arous al
theory and Maslow's hierarchy of needs.
In hunger motivation, we have looked at physiological
causes such as hunger pangs, body chemistry and role of
hypothalamus, weight set point and metabolic rate. In psychology
of hunger we have discussed that eati ng is a learned behavior.
Apart from that memory, taste preference, situational and cultural
factors also influence eating behavior. In obesity, we looked at what
is obesity, why it is important to study obesity and what causes it
and in waist management w e pondered over how we can reduce
and manage our weight. It is important to study obesity due to
biological, cognitive, social, and psychological issues. It is caused
due to biological and environmental reasons and tips to control it.

5.1 THE NEED TO BELONG: INTRODUCTION
Aristotle wrote that all human beings are social animals.
Even if people have all resources and amenities to live life
comfortably, but no social contact with other human beings, they
will choose not to live. They will prefer to live with others, even if it
means to live with limited resources. We all have a need to affiliate
with others, even to become strongly attached to certain others in
long lasting close relati onships. Alfred Adler called it an “urge to
community”. The question arises why do we have such strong
desire to affiliate with others. Psychologists believe that need to
belong is beneficial for human beings.munotes.in

Page 74

745.1.1Aiding in Survival:
Evolutionary psyc hologists explained that social bonds
increased the survival rate of our ancestors who were living in
forests and caves. Survival was enhanced by cooperation. In solo
combat, our ancestors could not fight back other animals who were
much stronger than them . Similarly, to get food by hunting, fishing
or by just collecting from plants, our ancestors realized that it is
better to hunt in team and share the spoils rather than try to hunt
individually. Travelling in group gave every one of them protection
from p redators and enemies.
Psychologists believe that all human beings have a strong
instinct to propagate their genes in next generation. As adults,
those who formed attachments were more likely to reproduce (have
children) and to co -nurture their offspring to maturity. By keeping
children close to their caregivers, attachments served as a powerful
survival impulse. Those who felt a need to belong survived and
reproduced more successfully. So being social is there in our
genes.
Good Health: Studies have sho wn that people who feel supported
by close relationships are the ones who live longer with better
health and at a lower risk of psychological disorder than those who
do not have social support, e.g. It was observed that married
people are less at risk for depression, suicide and early death.
Social isolation puts us at the risk of declining mental and physical
health.
5.1.2Wanting to Belong:
Most people report close, satisfying relationships with family,
friends, or romantic partners is the first and f oremost requirement
for their happiness and meaning in life. (Berscheid, 1985) Studies
show that money does not make a person happy, rich and
satisfying close relationship do. A person may be very rich and yet
unhappy and lonely. When our need to belong is satisfied in
balance with psychological needs of autonomy (having a sense of
personal control) and competence, we experience a deep sense of
well-being. (Deci & Ryan (2002) .When we feel included, accepted
and loved by those who are important to us, our s elf-esteem goes
up. Therefore, most of our actions are aimed at increasing our
social acceptance. To avoid rejection, we generally conform to
group norms and try to make favorable impressions.
The need to belong influences our need to define who we
are. W e express our identity in terms of faithful relationships and
loving families. We proudly say that I belong to so and so family.
However, our need to define who we are can be expressed in
negative way also. For example, we may become part of teen
gangs, we may become part of ethnic rivalries (our identity as
Hindu, Muslim, orSikh, etc.) and fanatic nationalism.munotes.in

Page 75

755.1.3Sustaining Relationships:
It is well known that generally familiarity produces liking.
Think of it. In a new class or conducted vacation tri ps, initially, we
are indifferent to other students /participants , who are total strangers
for us, but by the end of the course /vacation trip, parting ways and
breaking social bonds becomes a distressing experience and we
promise to keep in touch with each other. These friendships with at
least some of them becomes lifelong.
Our strong desire to maintain relationships with others ,no
matter how bad or abusive, are due to our fear of being alone.
Studies on abusive relationships have shown that people pre fer to
stay in abusive relationships and suffer emotional and physical
abuse rather than face the pain of being alone. People suffer
emotional trauma even when bad relationship breaks down. After
separations, people have feelings of loneliness and anger.
Sometime the yh a v e strange desire to be near the former partner
even if the relationship with former partner was not good.
Children who move through a series of foster homes or
through repeated family relocations, with repeated disruptions of
budding atta chments, may have difficulty in forming deep
attachments in later life. (Oishi &Shimmack, 2011 ).It has been
observed that children reared in institutions hav eno sense of
belonging to anyone, or children locked away at home under
extreme neglect become p athetic beings –withdrawn, frightened
and speechless.
Life’s best moments occur when close relationships begin,
e.g., when new friendship develops, we fall in love or when a new
baby is born in the family. The worst moments of life take place
when close relationship comes to an end. When some situation
threatens, or dissolves our social ties, we experience extreme
anxiety, loneliness, jealousy or guilt. When a person loses a life
partner, he or she feels that life has become empty and
meaningless. Forimmigrants and refugees moving alone to new
places ,the stress and loneliness can lead to depression for them.
But if the feeling of acceptance and connection increases, then our
self-esteem, positive feelings and desire to help others instead of
hurting oth ers also increases.
5.1.4The Pain of Ostracism:
This social exclusion is called ostracism. For centuries
together, humans have control ledsocial behavior by using the
punishing effect of severe ostracism. In extreme form, i tc a nb ei n
the form of exile, imprisonment or solitary confinement. In milder
form, it can be being excluded, ignored or shunned by your friends,
being given a silent treatment by not talking to you, by avoiding you
or averting his/her eyes in your presence or even making fun of youmunotes.in

Page 76

76behind your back. Williams & Zadro (2001) stated that being
shunned –given the cold shoulder or the silent treatment, with
others’ eyes avoiding yours -threatens one’s need to belong. This is
the meanest thing you can do to someone, especially when you
know that the other person can’t fight back. Even just being
linguistic outsider among people speaking a different language that
you can’t speak or understand must have made you feel excluded.
People often respond to social ostracism with depressed
moods. I n the beginning, they try to restore their acceptance and if
they don’t succeed, they go into withdrawal. People lose their self -
esteem and their weight drops. Experiencing cyber -ostracism is
equal to experiencing real pain. Ostracism (in the form of being
ignored in a chat room or email going unanswered) even by
strangers or by a despised out group takes its toll on the victim. It
activates the same area of brain that is activated in response to
physical pain. (Williams et.al.,2006).
When people experienc e rejection, and cannot rectify the
situation they seek new friends or gain stress relief by
strengthening their religious faith. They may turn nasty, may
indulge in self -defeating behaviors ,may underperform on given
tasks ,may not empathize with others and are more likely to behave
aggressively, especially towards those who had excluded them.
5.1.5Social networking:
Since social relationships are essential for leading a healthy
life, it is but natural for us to see how the progress of
communication tec hnology has significantly impacted satisfaction of
our need to have social contacts. Technology has changed the way
we connect with others and communicate. Texting, e -chatting and
e-mailing has replaced phone talking. With social networking being
pervasive in all aspects of our life it is important for us to see how it
impacts us.
The Social Effects of Social Networking :
As electronic communication becomes part of new normal ,
researchers are exploring how these changes affect our
relationships. The questi on asked by psychologists is “Are Social
Networking Sites Making Us More Or Less Socially Isolated?”
Research has reported that when online communication in chat
rooms and during social games was mostly between strangers in
the internet’s early years, adol escents and adults who spent more
time online spent less time with friends, and their offline
relationships in real world suffered.
Bonetti et.al. (2010) reported that lonely people tend to
spend greater than average time online. Social networkers are less
likely to know their real -world neighbors, and compared to non -munotes.in

Page 77

77internet users, are 64% less likely to rely on neighbors for help
either for themselves or for their family members.
However, social networking has its own advantages also.
The internet is diversifying our social networks. It is possible to
connect with likeminded people having similar interest from all over
the world. Geographical boundaries are broken. To a large extent,
social taboos are also broken. Despite the decrease in
neighborliness , social networking is mostly strengthening our
connections with people we already know. For example, we form
groups on Facebook and WhatsApp. If Facebook page helps you to
connect with friends, stay in touch with extended family, or find
support in facing challenges, then you are not alone.
Another phenomenon noticed on social networking sites is
that people disclose personal information to perfect strangers or for
the whole world to see that in normal circumstances they will not
like to disclose in real life. This observation brought another
important question to psychologists –Does Electronic
Communication Stimulate Healthy Self -Disclosure?
Mental health experts point out that confiding in others can
be a healthy way of coping with day to day challeng es. Very often
we find that people pour out their woes on social networking site.
For example, it was reported in TOI, dated 16thMay 2017, that a
film producer of Marathi films posted his suicide note on Facebook
before committing suicide. This is not isolated news. Before that
also, media has reported many such incide nts. The question arises
why people disclose their distress on social networking sites rather
than talking to somebody in their vicinity. There can be many
reasons for it such as:
1.People may not have any close friends to whom they can
communicate face to face about their problems.
2.While disclosing our distress face to face, we are not sure how
the other person is going to react. We are vulnerable and self -
conscious. It makes us feel weak and hits our self -esteem. On
the other hand, while communicating electronically rather than
face-to-face, we often are less focused on others’ reactions, feel
less self -conscious and thus feel less inhibited. We become
more willing to share our joys, worries and vulnerabilities.
Sometimes, this disinhibition can take an extreme form. For
example, people indulge in sexting, teens send nude photos of
themselves to their internet friends, youth are “cyber -bullied” or
trolling takes place, hate groups post message sp r o m o t i n g
bigotry or crimes.munotes.in

Page 78

783.Self-disclosure can also help to deepen friendships. Even if our
friendship with internet friends gets stronger, we crave to meet
them face to face. This is because nature has designed us for
face to face communication, whi ch appears to be better
predictor of life satisfaction. Texting and e -mailing are rewarding
but having face to face conversation with friends and family is
more enjoyable.
There are all sorts of people in virtual world just as they are
in real world. Some people are honest, loving good human beings
and some are cheats, criminals/ predators. Psychologists wondered
whether people reveal their true selves on internet. So the next
question is –Do Social Networking Profiles and Posts Reflect
People’s Actual Per sonalities?
Beck et.al. (2010) found that ratings based on Facebook
profiles were much closer to the participants’ actual personalities
than to their ideal personalities. This indicated that generally social
networks reveal people’s real personalities. I n another study, it was
found that people who seemed most likable on their Facebook
page also seemed most likable in face to face meetings also. This
also indicates that Facebook profile reflects real personality of the
person.
It has been observed that m ost of the people using social
networking sites are mainly talking about themselves. It is always
about me, my life, my family, my thoughts, my experiences etc. So,
another question that intrigued psychologists was -Does Social
Networking Promote Narcissi sm?
Narcissistic people are self –focused, self -promoting and
have an unusual sense of self –importance. They like to be the
center of attention. Such people on Facebook compare the number
of friends they have, the number of likes they get from others,
compared to their other friends. They are very active on social
media. Just to feel the pleasure of having maximum number of
friends, they collect more superficial friends. They post more
staged, glamorous photos of themselves just to get more likes.
Anyo ne who visits their Facebook page can judge that they are
narcissists. So, social media is not just a platform for all narcissists
to gather there, but it also satisfies their narcissistic tendencies
Maintaining Balance and Focus:
The question arises how to maintain balance between our
real world and the virtual world. Some of the suggestions offered by
experts are as follows:
1.Monitor your time :Keep a diary and see whether the way you
use your time reflects your priorities. Check whether the timemunotes.in

Page 79

79spent o n internet is interfering with your academic and work
performance and whether it is eating your time with friends and
family.
2.Monitor your Feelings: Check how you feel when you are not
online. Ifyou feel anxious and restless ,ifyou keep thinking
about s ocial networking sites all the time even when you are in
class or at work, then you are getting addicted to social
networking sites and you need help.
3.“Hide” your more distracting online friends: Before posting
anything on your social networking sites, as k yourself, is it
something that I would like to read if somebody else had posted
it?
4.Try turning off your handheld devices(mobiles) or leaving
them elsewhere: Cognitive psychologists point out that we
cannot pay full attention to two things at a time. Wh en you do
two things at once, you don’t do either of them as well as when
you do them one at a time. So while studying, resist the
temptation to check your social networking sites like WhatsApp /
Facebook. Disable sound alerts and pop -ups.
5.Try going on I nternet “Fast”: That means decide to go off
internet for five hours/ten hours or one day.
6.Recharge your focus with a natural walk: Research has
shown that walking in a quiet garden or in a forest recharges
people’s capacity for focused attention rather t han walking in a
busy street.

5.2 COGNITION AND EMOTIONS
Emotions are responsible for the finest inhuman
achievement and for the worst in history. They are the source of
pleasure as well as sorrow inour life. Negative and long lasting
emotions can make us sick. So, what are emotion s?Emotions are
our body’s a daptive response. They exist to give us support for our
survival. When we are faced with a challenge, emotions focus our
attention and energize our actions. (Cyders &S m i t h , 2008).
Emotions are a mix of bodily arousal (heart pounding), expressive
behaviors (quickened pace) and conscious experience, including
thoughts and feelings (panic, fear, joy). (Mayers D.G.,2013)munotes.in

Page 80

80Historical as well as current research has been trying to fin d
answer to two questions
1.Whether bodily arousal c omes before or after we emot ional
feelings ?
2.How do thinking (cognition) and feelings interact?
5.2.1Historical Emotion Theories:
1)A. James Large Theory: Arousal Comes Before Emotion
Common sense suggests that first we experience a feeling
and then consequently comes our action, e.g., we cry because we
are sad, tremble because we are scared. But James -Lange theory
proposes exactly opposite of that and states that feeling comes as
a consequence of our action, e.g., we feel sorry because we cry.
In other words, James and Lange wou ld say, “ I feel sorry
because I cry, I feel afraid because I tremble”. If a person sees a
bear while walking along in the woods, James and Lange would
suggest that the person would tremble and then realize that,
because they are trembling, they are afraid. He further stated that
without the bodily states following on the perception, the latter
would be purely cognitive in form, pale, colorless, destitute of
emotional warmth. We might then see the bear, and judge it best to
run, receive the insult and deem i tr i g h tt o strike, but we should not
actually feel afraid or angry.
2)The Cannon -Bard Theory:
Cannon disagreed with James -Lange Theory and stated that
people who show different emotions may have the same
physiological state ,e . g . , cry when happy and sad. The body’s
responses such as heart rate, perspiration and body temperature
are often too similar and too slow to cause different emotions,
which erupt very quickly, e.g., does racing heart signal fear, anger
or love? P hysiological arousal may occur withou tt h ee x p e r i e n c eo f
anemotion, e.g., exercise increases heart rate no emotional
significance. Cannon -Bard explained that our bodily responses
and experienced emotions occur separately but simultaneously,
e.g., The emotion triggering stimulus travels to sympathetic nervous
system, causing body’s arousal. At the same time ,i tt r a v e l st o
brain’s cortex, causing awareness of emotion. So, my pounding
heart did not cause my feeling of fear, nor did my feeling of fear
cause my pounding of heart.
However, Cann on-Bard’s theory has been criticized by those
doing research on spinal cord injuries. It was reported by them that
patients with high spinal cord injury (those who could feel nothing
below neck) reported changes in their emotions’ intensity. Patients
repor ted that the intensity of experienced emotion such as angermunotes.in

Page 81

81has come down drastically. One patient reported that “Anger just
doesn’t have the heat to it that it used to…” But other emotions that
are expressed mostly in body above the neck were felt more
intensely, e.g., these patients reported increase in weeping, lumps
in the throat and getting choked up when saying good -bye,
worshipping or watching an emotional movie. This indicates that
our bodily responses feed our experienced emotions.
5.2.2 Cognit ion Can Define Emotion: Schachter and Singer’s
Two Factor Theory:
Schachter and Singer maintain that we don’t automatically
know when we are happy, angry, or jealous. Instead, we label our
emotions by considering situational cues. Our physical reactions
and thoughts together create emotions. So, there are two factors –
physical arousal and cognitive appraisal. They also talked about
spillover effect .some element in the situation (e.g., you have
come home after a rigorous exercise) must trigger a general,
nonspecific arousal marked by increased heart rate, tightening of
the stomach, and rapid breathing. At that time, you get the good
news that you have got the job that you wanted for a long time. You
will feel more excited because of lingering arousal from t he
exercise. You would not have felt the same intensity of excitement
if you had just woken up from sleep.
To show this spillover effect, they conducted an experiment
in which volunteered were told that experiment was about the
effects of av i t a m i n calle dSuproxin. After volunteers c onsented
they were injected with epinephrine or a placebo. Epinephrine
triggers a feeling of arousal and generally increases blood
pressure, heart rate, and respiration. Thus, the men who received
the epinephrine were more physiologically aroused than those who
received the placebo. Schachter and Singer reasoned that once the
epinephrine’s effects take place, participants would begin to search
for the cause of their arousal and their reaction would depend on
the available situa tional cues. After administering injection, all
participants were asked to wait in a waiting room, where another
person (actually an accomplice of the experimenters) was already
present. This accomplice acted either euphoric or irritated.
Before going in to the waiting room some of the epinephrine
injected participants were told that there are some common side
effects of the drug -they might feel flushed, their hands might
shake, and their hearts might pound. The other subjects, in
contrast, were given no information at all about the effects of the
drug. Once the effect of epinephrine kicked in, p eople who were
told beforehand that the drug would arouse them felt no emotion
and assumed that the drug was causing their hands to shake and
their heart to pound and those who weren’t told about the drug’s
effects, interpret edtheir arousal as an emotion. As Schachter andmunotes.in

Page 82

82Singer had predicted, the physiologically aroused subjects who
hadn’t been told about the drug’s side -effects responded with
motions that matche d the confederate’s actions. If they were
aroused and hadn’t been expecting the arousal, then they felt
happy when the other person , i.e., confederate, was happy, but
angry when the other person was angry. Forewarned subjects and
unaroused subjects who rec eived a placebo did not display any
pronounced emotion. This finding that arousal state can be
experienced as one emotion or the other depending on how we
label it has been replicated in many other studies, indicating that
arousal fuels emotions, cognition channels it.
5.2.3 Cognition May Not Precede Emotion: Zajonc, LeDoux and
Lazarus’ Theory:
Zajonc believed that some of our emotional reactions involve
no deliberate thinking. He that our emotional responses follow two
different brain pathways. Some emo tions such as hatred and love
travel a “high -road” while other emotions such as simple likes,
dislikes and fears take “low road” . This low road is like shortcut that
enables our emotional response before our intellect interferes.
Lazarus said that our brains process vast amount of
information without our conscious awareness and that some
emotional responses do not require conscious thinking. Much of our
emotional life operates via the automatic, speedy low road.
However, we still need to appraise a situ ation to determine what we
are reacting to. This appraisal may be effortless and we may not be
conscious of it. In other words, he said that emotions arise when we
appraise an event as harmless or dangerous, whether we truly
know it is or not, e.g., we app raise the sound of the rustling bushes
as the presence of danger. Later on we might realize that it was just
the wind. So, some emotional responses -especially simple likes,
dislikes and fears involve no conscious thinking, e.g., we may fear
a snake and ou r emotion may not change in spite of knowing that
snake is harmless. However, studies have shown that highly
emotional people are intense partly because of their interpretations
and a lthough the emotional low road functions automatically, the
thinking high road allows us to retake some control over our
emotional life.
5.3 EMBODIED EMOTION: THE PHYSIOLOGY OF
EMOTIONS
Different emotions do not have sharply distinct biological
signatures and they do not engage very distinctly different brain
regions. For ex ample, insula, a neural center deep inside the brain
gets activated when we experience different social emotions such
as lust, pride and disgust. It gets activated with taste, smell or evenmunotes.in

Page 83

83thought of some disgusting food or even if we feel moral disgust
over a cheating case. However, researchers have identified some
subtle physiological distinctions and brain patterns for different
emotions, we can say that we cannot differentiate in emotions on
the basis of heart rate, breathing and perspiration, but diff erent
emotions have different facial expressions and brain activity.
Emotions and the Autonomic Nervous System:
By now, we know that autonomic nervous system helps in
moving our various bodily organs into action when the need arises
and parasympathetic nervous system helps in calming down our
bodily reactions. For example, when we are faced with a
challenging or exhilarating situation, our adrenal glands secrete
stress hormones , our liver releases more sugar in the blood stream
to provide more energy an d respiration rate goes up to provide
more oxygen. The digestion slows down to divert more blood from
internal organs to muscles and if you are wounded, the blood clots
more quickly to stop the bleeding. The pupil in the eyes dilates so
that more light com es in and you can see better. The perspiration
increases to cool your stirred -up body, etc. This kind of bodily
response is beneficial for better performance to meet the
challenges. Moderate arousal is needed to give better performance.
For example, can yo u imagine P.T. Usha winning a race if she was
not moderately aroused/tense (orwas sleeping) just before the race
started. However, having too much arousal/ tension or having too
little arousal/ tension before an important activity will not enhance
the per formance. One should not be too relaxed or too tense before
the important activity.
On the other hand, when the situation comes back to normal
and is no more challenging, the parasympathetic gradually calms
down the body and stress hormones slowly dissip ate from the
blood stream.
The Physiology of Emotions:
Different emotions neither have very distinct biological
reactions nor do they originate from specific distinct brain regions.
For example, the insula in the brain is activated when we
experience v arious social emotions such as lust, pride and disgust.
It does not matter that these feelings may originate from different
sources. For example, the feeling of disgust may originate from
taste of disgusting food, smell of disgusting food or just a thought of
some disgusting food or it may originate from watching a disgusting
news of corruption practiced by politicians.
However, studies have shown that even though biological
reactions and brain regions for different emotions appear to be
similar, there ar e emotions such as sexual arousal, fear, anger, and
disgust that are felt differently by the people and they appear to bemunotes.in

Page 84

84different to other people. Researchers have identified some subtle
brain pattern differences and physiological differences for differe nt
emotions. For example, the finger temperature and hormone
secretion related with fear and rage differ. Heart rate increases in
fear and joy but both feelings stimulate different facial muscles.
While experiencing fear, your eye brow muscles get tensed u pa n d
while experiencing joy, your cheeks and under your eyes pull into
smile.
Some emotions also differ in their brain circuits. People
show more activity in amygdala when they are watching fearful
faces rather than angry faces. Experience of negative emotions
such as disgust activates right side prefrontal cortex rather than left
side one. People with depression and negative personality in
general also show more right frontal activity. People with positive
personalities, that is people who are alert, e nthusiastic, energized
and persistently goal oriented, show more activity in the left frontal
lobe than in the right frontal lobe.
Thus, we can say that we can’t easily differentiate emotions
on the basis of bodily reactions such as heart rate, breathin ga n d
perspiration. But facial expressions and brain activity can differ with
emotions.
5.3.1Expressed Emotion :
A.)Detecting Emotions in Others:
To determine other people’s emotions we read their bodies,
listen to their voice tones and study their f aces. Psychologists
wondered whether non -verbal language differs according to our
culture and can our expressions influence our experienced
emotions. For example, in western culture, a firm handshake
conveys an outgoing, expressive personality. A gaze, an averted
glance or a stare indicates intimacy, submission or dominance. In a
study, male -female pairs who were total strangers to each other,
were asked to gaze intently at each other for two minutes. They
reported feeling a tingle of attraction towards eac ho t h e r .
Most of us read nonverbal cues well. We are especially good
at detecting nonverbal threats. In a crowd of faces, a single angry
face is identified much faster than a single happy face. Experience
can also sensitize us to particular emotions, e.g ., viewing a series
of faces depicting anger to fear, physically abused children were
much quicker to spot the signals of anger than non -abused
children. Hard to control facial muscles reveal signs of emotions
that a person may be trying to hide, e.g., eye brows raised and
pulled together signal fear. Our brains are very good detectors of
subtle expressions. Seeing a face for just 0.1 seconds also enabled
people to judge attractiveness or trustworthiness of a person (Willismunotes.in

Page 85

85&T o d o r o v , 2006). It is rightly sa id that first impression occurs at
lightning speed. Despite our brain’s emotion detecting skills, it is
difficult to detect deceiving expressions. The behavioral differences
between liars and truth -tellers are too minute for most people to
detect. However, some people are much better emotion detectors
(espec ially introverts) than others. It is difficult to detect emotions
from written communication because it does not have gestures,
facial features and voice tones to help detection of emotions.
Electronic c ommunication also provides very poor quality nonverbal
cues. That is why, people often use emoticons.
Lie Detection:
It is a common practice for researchers and crime detectors
to use lie detector -polygraph to detect the lies. The question arises
how ef fective and reliable is polygraph in detecting lies. The
polygraph works on the principle that certain emotion -linked bodily
changes, such as changes in breathing, cardiovascular activity and
perspiration changes take place when a person tells a lie, even if
that person can control his facial expressions. The tester/examiner
asksquestions to the testee and observe sthese bodily changes
taking place in the testee while answering the questions. The tester
starts questioning with certain question that may mak e any person
nervous and polygraph will show signs of arousal. These are called
control questions. For example, a tester may ask in last 10 years
have you taken anything that does not belong to you? The arousal
level shown on a polygraph, in response to th ese control questions
serves as the base line. Then the tester will ask the critical
questions, e.g., have you stolen anything from your previous
employer? The arousal level shown on polygraph in response to
this question will indicate whether the person i st e l l i n gt h et r u t ho r
lying. For example, if the arousal level while answering the critical
question is weaker than the base line arousal determined before,
then we can say that person is telling the truth. On the other hand,
if the arousal shown in respo nse to critical question is more than
base line arousal that means the person is telling the lie.
Criticism: It appears to be that simple, but it has certain criticism –
1. Our physiological arousal is almost same for various emotions
such as anxiety, ir ritation and guilt. So how do we know which
emotion a person was experiencing while answering that question?
2. Many innocent people get extremely tensed up while answering
a critical question that implies accusation. Lykken (1991) found that
many rape vi ctims fail this test because they react emotionally even
when they are telling the truth. On the other hand, Robert Park
(1999) noted that a Russian spy within CIA went undetected, even
though he took many polygraph tests and passed them all. Many
hardened criminals also pass this test without getting detected.munotes.in

Page 86

86Remedies: Psychologists are trying to find new ways to catch the
liars. For example, it has been suggested that instead of polygraph,
one should use ‘guilty knowledge test’. This test also assesses a
suspect’s physiological responses to crime -scene details that are
known only to police and to the guilty person. For example, if a
camera is stolen, then only a guilty person will react strongly to the
brand name of the stolen item. Thus, an innocent pe rson will rarely
get wrongly accused.
Psychologists are also training police to detect fleeting
signals of deceit in facial expressions .F o re x a m p l e ,w h e na
person is lying, he has to use more of his cognitive abilities (that
means, he has to think more), during such time his eye blinking will
decrease and once he has finished telling a lie, his eye blinking will
increase.
Some researchers are developing a software to analyze
the facial micro expressions or to compare the language of
truth -tellers and li ars. It is believed that liars use less of first
person pronouns and more of negative emotion words.
Forensic Neuroscience researchers are analyzing the EEG
recordings . It has been observed that liars’ brain activity can be
seen in fMRI scans while hones t people’s brains do not show any
such activity. A liar’s left frontal lobe and anterior cingulate cortex
becomes active when the brain inhibits truth telling.
B.) Gender, Emotion and Nonverbal Behavior :
Studies have proved that women are better at readi ng
emotional cues than men, even if they are exposed to very little
behavior of the other person, e.g., they can detect whether a male -
female couple is a genuine romantic couple or just pretending
one(Barnes & Sternberg, 1989). Women’s nonverbal sensitivity is
due to their greater emotional literacy and they more emotionally
responsive. For example, in an experiment on emotional literacy,
when men were asked how will they feel saying good bye to a
friend, they simply said, “I will feel bad”, while women said “It will be
bittersweet; I’ll feel both happy and sad”.(Barrett et.al., 2000). A
study of people from 26 cultures found that women reported
themselves as more open to feelings than men. (Costa et.al. 2001).
This clearly indicates that women are more emoti onal than men.
However, generally, people tend to attribute women’s reactions to
their emotions while men’s reactions to their circumstances, except
for the feeling of anger. Anger is considered as more masculine
emotion. Surveys showed that women are more likely to describe
themselves as empathic. Their heart rate goes up and they are
more likely to cry when they see someone in distress.munotes.in

Page 87

87C.) Culture and Emotional Expression:
Studies have shown that there are universal facial
expressions for basic emotio ns across different cultures. Facial
muscles speak a universal language. In entire world, children cry
when in distress and smile when they are happy. Even people blind
from birth, naturally show the common facial expressions linked
with emotions such as j oy, sadness, fear and anger. Musical
expressions also cut across cultures. In all cultures, fast paced
music seems to be happy one and slow music is considered as sad
one.
Charles Darwin said that in prehistoric times, before our
ancestors communicated through words, they communicated
threats, greetings and submission through facial expressions. Their
shared expressions help in their survival. Emotional expressions
help in our survival in other ways also, e.g., surprise raises the
eyebrows and widens the eyes so that we can take in more
information. However, it is observed that people are more accurate
in judging emotions from their own culture , and there are cultural
differences in how much emotion will be expressed. For example,
in western culture, peop le openly show their emotions while in
Asian cultures, people tend to have less visible display of their
emotions.
D.)The Effects of facial Expression:
Studies indicate that expressions not only communicate
emotions, they also amplify and regulate the m. People report
feeling more fear than any other emotion, when made to construct
a fearful expression. It is said smile warmly on the outside and you
will feel better on the inside. So, your face feeds your feelings. In an
experiment, depressed patients f elt better after getting Botox
injections that paralyze the frowning muscles. Similarly, it is
reported that people see ambiguous behaviors differently
depending on which finger they move up and down while reading a
story. If they read the story, while mov ing an extended middle
finger, the story behaviors seemed more hostile. If read with a
thumb up, they seemed more positive.
5.3.2Experienced Emotions: Anger and Happiness
The experience of emotions in human beings can be placed
on two dimensions –Positi ve vs. Negative and Low Arousal vs
High Arousal. Any emotion is a combination of these two
dimensions. For example, if we take emotion of anger, then
enraged is angrier than angry (at arousal level) and it is a negative
feeling. Let us discuss two of the m ost noticeable and pervasive
emotions that impacts our lives. These are anger and happiness.munotes.in

Page 88

88Anger:
Ancient wisdom describes anger as ‘a short madness’. It
says that anger ‘carries the mind away’ and can be ‘many times
more hurtful than the injury that caused it’. In other words, it is
trying to say that when we are angry, we can’t think rationally and
may do or say things that ultimately causes more misery to us.
However, Shakespeare held a different view and said that noble
anger makes a coward person brave and energizes us. Who is
correct? The answer is both are right. Anger can harm us. Studies
have shown that chronic hostility can cause heart disease, blood
pressure, lead to impaired social relationships and may even
shorten our lives.
The questio n arises can we get rid of our anger? If yes, then
how?
Gender Differences: A Gallup teen survey showed that there
are gender differences in dealing with anger. It reported that to get
rid of their anger, boys usually move away from the situation that is
causing them anger, they do lot of physical activities such as
exercising to get over their anger. On the other hand, girls cope
with their anger by talking to a friend, listening to music or writing
down in diary or journal.
Cultural Differences: Western culture ,a predominantly an
individualistic culture ,believes that people should vent their anger,
because internalizing the feeling of anger is more harmful. In fact ,
‘recovery’ therapists encourage people to vent their rage against
our dead parents, conf ront our childhood abuser and curse our
boss in our imagination. Keeping anger within us is considered bad
for our mental and physical health. Western culture believes that
venting out of anger can be done through emotional release (either
through aggressi ve act or through imaginary act) or catharsis.
There is some empirical support for this line of thinking. Studies do
show that sometimes, not always, the anger subsides when people
retaliate against a provoker. But anger subsides only if aperson
counterat tacks directly his provoker ,retaliation is justifiable ,their
target is not intimidating (Geen et.al., 1977) and if they do not feel
anxious or guilty later on. If anger led physical or verbal acts
generate regret later on, it becomes maladaptive.
Howeve r, catharsis often fails to erase our feeling of rage.
There can be some reasons for it
1.Expressing anger may strengthen the anger instead of
reducing it :e.g., in case of road -rage. Ebbesen et. al. (1975)
conducted an experiment on laid off employees. Th ey were allowed
tovent their hostility and later on given chance to express their
attitude towards the company. Compared to those laid off
employees who were not given a chance to vent their hostility inmunotes.in

Page 89

89initial questionnaire, it was found that employees who were given
such a chance in firstquestionnaire, expressed more hostility. Their
hostility increased instead of reducing . Similar results were reported
by another study .Brad Bushman (2002) rightly said that venting to
reduce anger is like using petrol to put out a fire.
2.It may provoke retaliation and a minor conflict may turn
into major confrontation :In Asian culture, which is a community
culture, giving vent to your aggression in this manner is considered
bad. People don’t give went to their rage because they derive their
identity from the group and have a sense of interdependence. Such
people consider venting their anger as a threat to group harmony.
3.Angry outbursts are dangerous in another way :They may
temporarily calm us but this may act as r einforcement and so may
be habit forming.
4.Anger can lead to prejudice :Americans developed prejudice
against immigrants and Muslims after 9/11.
Techniques to Control Anger:
1.Wait before reacting. You can bring down the level of
physiological arousal of anger by waiting.
2.Don’t ruminate. Ruminating inwardly serves to increase it
3.Calm yourself by exercising, playing an instrument or talking it
through with a friend.
4.Anger when used wisely can be a strength and can benefit the
relationship. Express the gri evances in ways that promotes
reconciliation rather than retaliation.
5.Talk things over with the offender, thereby reducing the
aggravation. Be civil but assertive.
6.If conflict can’t be resolved, use forgiveness. Forgiveness
releases anger and calms the bo dy.
Happiness :
Happiness is a state of mind or a feeling of contentment,
satisfaction, pleasure, or joy. ’Positive psychology, describes
happiness as a high ratio of positive to negative feelings or sense
of satisfaction with life.
A)Importance of Happ iness in Our Lives:
Happiness /unhappiness has tremendous impact on each
and every aspect of our lives. This impact can be temporary or long
lasting, mild or severe. Psychologists have been investigating the
difference between happy and unhappy people and how it affects
them. Some of the conclusions are that happy people perceive the
world as safer and they feel more confident, make decisions and
cooperate more easily, are more tolerant, rate job applicants moremunotes.in

Page 90

90favorably, savor their positive past experien ces without thinking too
much on the negative aspects, are more socially connected ,live
healthier and more energized and satisfied lives (Mauss et.al.,
2011) ,earn significantly more money (Diener et.al.,2002).
Baas et.al. (2008) stated that when your mo od is gloomy, life
as a whole seems depressing and meaningless, you are critical of
your surroundings and thinking is skeptical, in such a situation, if
you put in efforts to brighten your mood, your thinking will get
broadened and you will become more pla yful and creative. In other
words, you will get transferred from unhappy state to happy state.
When we are happy, our relationships, self -image, and hopes for
the future also seem more positive.
Feel -Good, Do -Good Phenomenon: Many research studies
have reported that happiness doesn’t just feel good, it does good ,
e.g., in many studies, mood boosting experiences (such as finding
money, recalling a happy event, etc.) had made people more likely
to give money, pick up someone’s dropped papers, volunteer t ime
and do other good deeds. Reverse of feel good and do good was
also found to be true. When you do good for someone, you feel
good.
B)The Short Life of Emotional Ups and Downs:
Studies have shown that over the long run, our emotional
ups and downs te nd to balance out, not only over the days but also
during the day. Positive emotion rises over the early to middle part
of most days and then drops off. A stressful event can trigger a bad
mood, but by the next day, the gloom almost always lifts. Even
when negative event persists for longer period, our bad mood
usually ends. For example, romantic breakup feels devastating, but
eventually the emotional wound heals and we move on in life.
Grief over the loss of a loved one or anxiety after a severe
trauma s uch as child abuse, rape, or the terrors of war, may last for
longer period, but eventually we get over it. No tragedy is
permanently depressing. People who become blind or get
paralyzed too recover near normal levels of day to day happiness.
People cop e well with a permanent disability, though they do
not rebound back to former emotions of happiness and well -being.
A major disability leaves people less happy than average, yet much
happier than able bodied people suffering from depression. Bruno
et.al. ( 2008) commented that most patients “locked -in” motionless
body( being in coma) do not say they want to die. The fact is that
we overestimate the duration of our emotions and underestimate
our resiliency and capacity to adapt.munotes.in

Page 91

91C)Wealth and Well -Being:
To some extent, wealth does correlate with well -being, e.g.,
rich people are typically happier, healthier than poor people who
lack control over their lives. Money can help to get out of hunger
and hopelessness and also buy happiness. But once you have
sufficient money for comfort and security, adding more money does
not add to more happiness. This is because of diminishing returns
of phenomenon. The power of more money to increase happiness
is significant at low incomes and diminishes as income rises. In
every culture, those who strive hardest for wealth tend to live with
lower well -being, especially if they are seeking money to prove
themselves, gain power or show -offrather than support their
families .
D)Two Psychological Phenomena -Adaption and Compar ison:
There are two psychological phenomena that explain why
happiness is relative. These are Adaptation and Comparison. Let
us understand these two principles –
1)The Adaptation -Level phenomenon: This principle suggests
that we have a natural tendency to judge various stimuli in
comparison to our past experiences. Harry Helson (1977) explain
this phenomenon by explaining that on the basis of our past
experience, we all reach certain neutral levels for everything ,e . g . ,
there are certain levels at which we will not find sounds either too
loud or soft, temperatures as too high or low, events as pleasant or
unpleasant. We will feel just neutral about them. Once these neutral
points are developed, then we judge any new events or variations
in existing event s in comparison to these levels ,e . g . , if temperature
goes higher than our neutral point temperature, then we find
temperature too hot for our comfort.
Similarly, if compared to our present income we get higher
income, we feel a temporary surge in our happiness, but later this
new high becomes the new normal level and then to again feel
happy we will require income more than this new normal level also.
Same is true for other areas such as academic rewards, social
prestige, etc. For example, do you remember ,t h et h r i l ly o uh a d
when cordless phones came in the market and you owned one
(Those phones work edonly within a limited range of landline
phones, giving you very little flexibility). Later, mobile phones came
into market and they gave you the freedom to talk to anyone even
while traveling far away from your home. At that stage you were no
more thrilled with cordless phones. Afterwards, mobiles got
upgraded to smart phones and now you could not only talk with
mobile phone but could also do lot more like us ing internet on
phone. Now does ordinary mobile phone gives you any happiness
or excitement? The answer will be no. This is exactly what the
psychologists meant when they said happiness is relative to our
own experiences.munotes.in

Page 92

92There is no permanent happiness. Tomorrow, suppose you
get a chance to live in an ideal world where you don’t have any
economic worries or health worries and your near dear ones give
you unconditional love. You will be elated, but after some time you
will adjust your adaptation level an dt h i sn e ww o rld will become
your new normal . Now you will feel satisfied if events exceed your
expectations or you will feel dissatisfied if these events fall below
your expectations. The point is that satisfaction or dissatisfaction
are just our judgment s based on our past experiences.
2)Comparison -Relative Deprivation :We always compare
ourselves to others and our feeling of good or bad depends upon
with whom we are comparing. Seeing many others getting rich may
create a sense of relative deprivati on.Such comparisons are the
reason why rich people are more satisfied with life than the poor
people. However, Russell (1930,p90) noted very aptly that
“Beggars do not envy millionaires, though of course they will envy
other beggars who are more successfu l”.Comparing ourselves with
those who are better off creates envy and comparing ourselves with
those who are worse off creates contentment.
E)Predictors of Happiness:
Happy people share many characteristics such as they have
high esteem ,are optimistic ,o u t g o i n ga n da g r e e a b l e ,have close
relationships or a satisfying marriage ,have work and leisure that
engages their skills ,have an active religious faith ,sleep well and
exercise Research shows that age, gender, parenthood and
physical attractiveness ha s no link with happiness, but genes
matter .
Heritability: In one study of identical and fraternal twins, it was
found that about 50% of the difference among people’s happiness
ratings was heritable. Other studies have also indicated that
identical twins raised apart are often similarly happy.
Personal History and Culture: On the personal level, we already
know that our emotions tend to balance around a level defined by
our experiences. On the cultural level, groups differ in the traits that
they value. For example, self -esteem and achievement are more
important to Westerners due to emphasis on individualism. Social
acceptance and harmony are more important for people living in
communal cultures such as Japan, where family and community is
more important than personal achievements. However, apart from
our genes, studies indicate that relationship quality is also an
important determinant of our happiness.
So, depending on our genes, our values, our recent
experiences, our happiness seems to fluctuate arou nd our
“happiness set point”. Due to this some people are always happymunotes.in

Page 93

93while others are always negative. However, psychologists believe
that our satisfaction with our lives is not fixed. Happiness can
increase or decrease. It can be influenced by factors u nder our
control.
5.3.3Close up: Want to be Happier?
Our happiness, like our cholesterol levels, is genetically
influenced. As cholesterol can be kept under check through diet
and exercise, similarly, level of happiness can also be partly kept
under our control. Researchers have given some research based
suggestions to improve our mood and satisfaction of life. These
suggestions are –
1.Realize that long lasting happiness may not come from
financial success :We adapt to changes by adjusting our
expectati ons. Neither wealth nor any other circumstances that we
desire can guarantee happiness.
2.Take control of your time: Happy people feel in control of their
lives. To manage time, set goals and break them into sub -goals for
daily aims. It will be difficult an d frustrating because you will find
that first of all it is not possible to set goals ,then break them into
daily sub -goals. We need to have very clear and systematic
thinking for that. Another problem is that human beings have a
natural tendency to overes timate how much work they can
accomplish in any given time ,e . g . , you may set a goal that you will
finish studying the present chapter in a day. At the end of the day,
you may realize that you have not been able to finish it for various
reasons. So, to avo id disappointments and frustration, one needs to
practice setting up realistic goals and organize the daily activities
accordingly.
3.Act Happy: Empirical research showed that when people were
manipulated to put on a smiling expression, they felt better. So ,p u t
on a happy face, laugh more, talk as if you feel positive self -
esteem, being optimistic and outgoing. We can often act our way
into a happier state of mind.
4.Seek Work and leisure that engages your skill: Happy
people are often in a zone called “flo w”–that is, they are absorbed
in tasks that challenges but does not overwhelm them. The most
expensive forms of leisure often provide less flow experience than
simple activities such as gardening, socializing or creating
something new. Money also buys mo re happiness when spent on
experiences that enjoy, remember, and look forward to rather than
when money is spent on buying some material stuff such as
expensive mobile or clothes.munotes.in

Page 94

945.Joint the “Movement” movement: It has been found that
aerobic exercise can relieve mild depression and anxiety as it
promotes health and energy. Sound mind resides in sound body.
6.Sleep Sufficiently: Give your body the sleep it wants. Happy
people live active lives, yet reserve time for renewing sleep and
solitude. Now days, ma ny people suffer sleep debt that results in
fatigue, diminished alertness and gloomy mood. They remain
irritable throughout the day that can have further negative
experiences.
7.Give Priority to Close Relationships: Intimate friendships can
help you to sail through difficult times. Confiding is good for soul as
well as for body. It has been noticed that compared to unhappy
people, happy people engage less in superficial talks and more
meaningful conversation. Nurture your close relationships by not
taking yo ur loved ones for granted. Show them the sort of kindness
you show to others, affirming them, playing together and sharing
together.
8.Focus beyond Self: Reach out and help those who are in
need. Happiness increases helpfulness but doing good also makes
onef e e lg o o d .
9.Count Your Blessings and Record Your Gratitude: Keep a
gratitude journal, that is keep a register where at the end of the day,
remember and enjoy good moments once again and write in that
journal all positive events that occurred that day and why they
occurred. You also write express your gratefulness to others in that
journal. It is scientifically proven that keeping gratitude journal
heightens one’s well -being.
10.Being Happy is a Matter of Choice: It is our attitude that
makes us feel happy or unhappy. It is true, we meet all kinds of
situations during the day, and some of them may not be conducive
to happiness. We can choose to keep thinking about the unhappy
events, and we can choose to refuse to think about them, and
instead, relish the ha ppy moments. If we let outer events influence
our moods, we become their slaves. We lose our freedom. We let
our happiness be determined by outer forces. On the other hand,
we can free ourselves from outer influences. We can choose to be
happy, and we can do a lot to add happiness to our lives.
11.Surround yourself with happy people: It is easy to begin to
think negatively when you are surrounded by people who think that
way. Conversely, if you are around people who are happy their
emotional state will be inf ectious.munotes.in

5.4SUMMARY
In this unit, we have touched upon three learning items -
need to belong, emotions and happiness.
In need to belong, we looked at the definition and usefulness
of need to belong. We also discussed how ostracism is painful for
anybody and in social networking topic we discussed how
technology has impacted our social communications. We also
looked at the ways and means of maintaining a balance between
real world and internet world.
In e motions we first talked about its definition, and w e
discussed fo ur historical theories of emotion to see the link between
cognition and emotions. The James Lange theory propose dthat
first comes bodily response and then we label emotions based on
those bodily responses. Cannon -Bard ’s theory argue dthat
emotions and autonomic responses occur simultaneously but
separately . One is not the cause of the other. The individual’s
appraisal of the emotion producing situation largely determines the
emotions.
Schachter and Singer believed that to experience emotions,
we must consciously interpret and label them. Zaj onc, LeDoux and
Lazarus noted that we have many emotional reactions without
interference of intellect. Many emotions occur without our being
aware of them. Then we discussed the physiology of emotions and
how emotions can be detected by others. We also dwe lled upon
how gender and culture can influence the expression of emotions,
and how facial expression can influence the actual experience of
emotions.
Lastly, we discussed about experiencing two major
emotions, that is, anger and happiness. We saw in det ail what are
the consequences of anger and how it can be controlled. In case of
happiness, we discussed the definition, nature of happiness and
how there is a positive yet limited connection between wealth and
feeling of well -being. How two psychological p henomena -
adaptation and comparison can influence the experience of
happiness. Finally, we looked at the predictors of happiness and
how happiness can be increased.munotes.in

6.1 INTRODUCTION
Though all human beings are similar in many waysthey
perceive, learn, remember, think and feel, yet there are individual
differences and each one of us is unique. These differences and
uniqueness is due to personality differences. Personality is anmunotes.in

Page 98

98important dimension of individual differences. Personality has been
the area of interest for psychology for more than 100 years. This
and the next unit would provide an exposure to different personality
theories, ranging from classical to contemporary. This u nit
discusses psycho dynamic and humanistic theories of personality.
The next unit discusses trait and socio -cognitive theories of
personality.
Personality can be considered as sum -total of who you are –
emotions, attitudes, motives, and behaviour. No two people are
same because they have different personality.
Personality is unique and relatively stable way in which
people feel, think, and behave throughout the life.
Personality can be defined as a person’s characteristic
pattern of thinking, feeling, an d acting (Mayers ,2013).
6.2PSYCHODYNAMIC THEORIES
Psychodynamic theories of personality consider human
behavior as a dynamic interaction between the conscious and
unconscious mind and its associated motives and conflicts. These
theories originated from Sigmund Freud’s psychoanalysis theory
and later on Neo -Freudian theories were included. So, let us begin
with psychoanalytic perspective.
6.2.1 Freud’s Psychoanal ytic Perspective: Exploring the
Unconscious :
Sigmund Freud was born 1856 . That was a Victor ian era in
Europe –a time of tremendous discovery and scientific
advancement, but also a time of sexual repression and male
dominance. In general, only male sexuality was acknowledged and
that too very discreetly. Freud was very independent, brilliant and
voracious book reader right from his teens. He became a doctor
specializing in nervous disorders and started a private clinic. Very
soon he became famous because of his work in psychiatry. Till
today his influence lingers in psychiatry and clinical psycho logy as
well as in many other courses.
Many of his patients were rich females, and while treating
them he realized that they had disorders without any neurological
base, e.g., a patient may complain that she has lost all sensations
in her hand and yet he observed that no sensory nerve was
damaged that would numb only the entire hand but nothing else.
Freud’s search for a cause for such disorders made him realize that
some neurological disorders can have psychological causes. He
called his theory of person ality and the associated treatment
techniques as Psychoanalysis. In his personality theory, hemunotes.in

Page 99

99emphasized first of all on division of mind, then on structure of
personality, psycho -sexual stages of personality development and
defense mechanism.
Division o ft h eM i n d :
Freud believed that mind is divided i nto three parts. The
conscious, the preconscious, and the unconscious.
1)The Conscious Mind :
The conscious mind is the uppermost part of the mind. It
contains information one is aware of at any given time .T h i si s an
Individual’s current perceptions, memories, thoughts, fantasies,
feelings th athe is aware of .It is quite close to short -term memory
concept which you have studied in earlier chapters. Freud believed
that mind is mostly hidden and the conscio us awareness is like the
part of an iceberg. In other words, what we are aware of is a very
small part of our consciousness and beneath this awareness is the
large unconscious mind with its thoughts, wishes, feelings and
memories.
2)The Preconscious Min d:
The preconscious mind contains ideas, feelings, events,
concerns beliefs, thoughts that person is not aware at present but
can easily be made accessible to the conscious. This contains
memories that are not at the moment in the conscious thought
proces s, but can readily be brought to mind whenever needed. It
works closely with the conscious mind. Today, it can be called as
explicit long -term -memory. But Freud suggested that these two are
the smallest parts of mind .
3)The Unconscious Mind:
The unconsc ious mind (often called as “the unconscious”) is
the most central and significant part of Freudian theory. The
unconscious is most important determinant of human personality
and behaviour. According to Freud, the unconscious is a mass of
unacceptable passi ons and thoughts that he believed we repress or
forcibly block from our consciousness because it would be too
stressful to acknowledge them. These are the major source of our
motivations ranging from simple desires for food, and sex to the
complex motives like creativity of an artist. This largest part of mind
remains hidden to conscious. Without our awareness, these
troubleshooting feelings and ideas powerfully influence us,
sometimes getting expressed in disguised form such as dreams,
slip of tongue or pe n,the work we choose, the beliefs we hold, our
daily habits, or other behavior that people carry out without
understanding the reasons for it. He believed that nothing is ever
accidental and considered jokes as expression of repressed sexual
and aggressiv e tendencies and dreams as the “royal road to the
unconscious”. In dream analyses, he searched for patients’ inner
conflicts.munotes.in

Page 100

100To gain access to patients’ unconscious mind, initially he used
hypnosis. But that did not work. So, he devised a new method
called“Free Association”. In using this method, he asked his
patients to relax and say whatever came to their mind, no matter
how embarrassing or trivial it is. He assumed that certain mental
blocks from patient’s distant past are responsible for his troubled
present and free association will allow him to retrace th ose mental
blocks, allowing him to peep into patient’s unconscious mind and
retrieve and remove painful memories stored from his childhood.
Personality Structure:
According to Freud, personality ca nb ed i v i d e di n t ot h r e e
parts. They dynamically interact with each other. They are: Id, Ego,
and Superego.
1)ID:
The first and primitive part of personality is Id. It is present
since infancy. It is completely unconscious and amoral. It contains
all the basic biological drives to survive, reproduce and aggress.
The id is the impulsive, child -like portion of the psyche that
operates on the “pleasure principle”. The pleasure principle states
that there should be immediate gratification of the needs witho ut
caring about outside world’s restrictions or societal conventions of
civilized, standard, and moral behaviour. People dominated by ID
will concentrate on present pleasure rather than think about future
pleasure, e.g., they will enjoy parties, mov ies no wr a t h e rt h a n
sacrifice today’s pleasure for future success and happiness.
Freud believed that human personality is the result of our
efforts to resolve these conflict sbetween impulses and restraints
between our aggressive, pleasure seeking biological u rges and our
internalized social control over these urges.
2)EGO:
This second part of personality is developed to handle the
reality. It is partially conscious part of mind that includes our higher
cognitive abilities, rationality, perceptions, thought fulness,
memories, learning, and logical processes. It provides buffer
between illogical, amoral impulses of id and societal restrictions.
The Ego works on reality principle , which means that the id’s drives
are satisfied in a realistic way that will avoid negative outcomes and
will bring long term pleasure. So,there are times when ego denies
the gratification of id’s drive because of possible negative
consequences. For example, if a very young kid is hungry, then he
picks up food from anybod y’splate, but slightly older kids will not do
that. Instead they would wait for their plate to come or make a
request in more formal ways. If they are at stranger’s place, then
they will prefer to stay hungry than asking for food. This is because
ego develops with the age.munotes.in

Page 101

1013)SUPEREGO:
Freud believed that around the age of 4 or 5 our superego
starts developing and ego starts recognizing the demands of
superego. Superego represents our moral values imbibed from the
society. These are the rules and regulations about wha ti sr i g h ta n d
wrong taught by parents, teachers, and important others. The
superego tells us how we ought to behave. It forces ego to consider
not only the real world but also the ideal world. In other worlds, it
tells ego to not only avoid punishment but also to strive for ideal
behavior. It strives for perfection. It prevents us from doing morally
incorrect things, by producing guilt (also called as moral anxiety ). It
produces feeling of pride when we do morally correct things. A
person with very strong superego may be virtuous and yet guilt -
ridden, while another person with weak superego may be low in
using self -restraint and yet may not feel any guilt.
Fig. 6.1
Since t he Id is unrealistically impulsive and the superego is
unrealistical ly moralistic, the id and superego’s demands are
always in conflict, the ego tries to strike a balance between the two.
The ego is the “executive” part of the personality. It mediates
between the impulsive demands of the id and the restraining
demands of t he superego and the real life demands of the external
world. Anxiety is created when ego cannot meet their needs.
Extreme anxiety leads to disorders. The Psychological Defense
Mechanisms are used to deal with anxiety and stress created by
conflicts between the three components of personality. They are
unconscious strategies people use to deal with the anxiety and by
distorting the reality. They have been classified as psychotic,
immature, neurotic and healthy defense mechanisms. But before
talking about def ense mechanisms in detail let us look at the
developmental stages of personality.
Developmental Stages of Personality:
Freud proposed that development of personality takes place
when a child passes through a series of psychosexual stages.
Freud has iden tified particular body parts as a focus of specific
munotes.in

Page 102

102developmental stage. In each psychosexual stage, id’s pleasure
seeking energies focus on specific body parts that provide
sensation of pleasure during that stage. It is called as erogenous
zone .In every psychosexual stage, there is a conflict between id,
ego and superego. Conflicts unresolved during earlier
psychosexual stages could lead to maladaptive behavior in the
adult years. These stages are Oral, Anal, Phallic, Latency, and
Genital .

Page 103

1031)Oral Stage :
The duration of first stage of psychosexual development,
namely Oral Stage ,i sf r o mb i r t ht o1 8m o n t h s . The erogenous zone
of oral stage is mouth. Children enjoy activities like sucking, biting,
mouthing, etc. The conflict that is experienced in this stage is
weaning the child from bottle or mother’s breast feed. The child will
get fixated in the oral stage if the child overindulges (continue to
breast /bottle feed for longer duration)or become frustrated (due to
early or abrupt weaning) with the oral gratification. This leads to
development of oral personality in adulthood. Aggressive -
pessimistic traits develop if oral needs are under gratified and
dependency -optimism develops if they are over gratified. Ift h e ya r e
over gratified, they may continue to seek oral gratification by
overeating, talking too much, smoking, etc. If they are weaned
away too early leading to under gratification they may act tough or
speak in “bitingly” sarcastic way, etc.
2)Anal Stage:
The duration of Anal Stage of psychosexual development is
from 18 months to 3 years. The erogenous zone of anal stage is
anus. Children at this stage derive pleasure by both wi thholding
and expulsion of fesses at will. In addition to physical pleasure,
child also derives pleasure from self -control and the praise from
parents. The conflict that is experienced in this stage is toilet
training. The child will get fixated in the ana l stage if toilet training is
too harsh. The conflict leads to development of anal personality in
adulthood. They are of two types: anal expulsive personalities and
anal retentive personalities .Anal Expulsive Personality results from
child’s rebel against toilet training by parents. The adult would show
destructiveness, hostility, emotional outbursts, disorganization ,
rebelliousness and carelessness. They could also become
extremely generous and indiscipline .Anal -Retentive Personality
develops d ue to fear of punishment .The child retains fesses and
refuses to go to toilet. They develop traits like excessive
orderliness, neatness, stubbornness, a compulsion for control and
have interest in collecting, holding, and retaining objects.
3)Phallic Stage:
The Phallic Stage is between 3 years to 6 years. The
genitals are erogenous zone during this stage. Child derives
pleasure by fondling genitals. They develop unconscious sexual
desires for their mother and jealousy and hatred for their fathers,
whom they cons ider as their rivals. Similarly, girls develop
unconscious sexual desire for their fathers. Boys experience
Oedipal Conflict and girls experience Electra Complex inthis
phase. Father is perceived as powerful, and they develop castration
anxiety, af e a rt h at their penis will be cut -offby their fathers, if
fathers come to know of their sexual attraction towards their
mothers .T or e s o l v e this anxiety boys Identify with their father sa n dmunotes.in

Page 104

104girls identify with their mothers .T h i si s called as Oedipus complex.
According to Freud, girls get attracted to father and experience
penis envy ,feeling of inferiority for not having th atanatomical part.
They held mother responsible for this. To resolve this conflictual
feeling towards mother, girls identify with mother. No rmal sexual
development occurs if the conflict is resolved. Immature sexual
attitudes, promiscuous or sexually inhibited behaviour, and sexual
confusion in adulthood may result from fixation in phallic stage.
4)Latency Stage :
The duration of this stage is from 7t o1 2 years. The sexual
feeling of child isrepressed in unconscious, or kept latent ,and the
child grows physically, intellectually, and socially. This is relatively a
calm stage where sexual energy is converted into interest in
excelling in sc hool work and sports, etc.
5)Genital Stage:
The duration of this phase is from 13 years onwards till
death. The mature, adult sexuality develops during this stage. At
this stage, once again the attention is shifted to genitals but sexual
attraction is shifted from one’s parents to members of the opposite
sex. Sexual urges are expressed through socially approved
channels. Sex takes a matured form by moving from desire for
pleasure only to a desire for reproduction. The sexual and
aggressive motives are transferred into energy for marriage,
occupation and child rearing.

Freud held that anxiety is the price we pay for civilization.
There is a constant tug of war between id and superego and ego
has to balance both of them. Sometimes, ego fears losing control
over this inner war and we experience anxiety. At such times, ego
protects itself with defense mechanisms, i.e., the tactics used to
reduce or redirect anxiety by distort ing reality. All these defense
mechanisms work at unconscious level and ego unconsciously
defends itself against anxiety. Some of these defense mechanisms
are discussed here.munotes.in

Page 106

1066.2.2TheNeo-Freudian and Psychodynamic Theoris ts:
Freud’s theory has been c riticized as well as praised by his
contemporaries and by other psychologists later. Those who
followed broad framework of Freud and developed their own
theories of psychoanalysis are called as Neo-Freudians .Neo-
Freudians accepted his basic ideas such as personality structure of
id, ego, superego; the importance of the unconscious; the shaping
of personality in childhood; and the role of anxiety and defense
mechanisms in personality development. However, they did not
agree with the idea that only sex and a ggression are dominant
motives in our lives. They believed that social interaction also plays
an important role. Similarly, while accepting the role of unconscious
mind they emphasized the role of conscious mind also in
interpreting our experiences and in coping with our environment.
Some of the important Neo -Freudian theorists are Jung, Adler,
Horney, etc.
Carl Jung :
Carl Gustav Jung differed from Freud on the nature of
unconscious and parted away from Freud. In addition to Personal
Unconscious ,h ed e v e loped the concept of Collective Unconscious .
It is the store house of our experiences as a species since ancient
ages. We are born with it and are not conscious of it. He called
these collective universal human memories as Archetypes, an
unlearned inclinat ion to experience world in a particular way.
Among the many archetypes, Mother (our inner tendency to identify
a particular relationship of “mothering”), Anima/Animus (feminine
component within males/ masculine component within females),
Shadow (dark side o f ego containing sex and life instincts), persona
(individuals public image) are important.
Jung was initially Freud’s disciple but later turned his
dissenter. While he agreed with the idea that unconscious exerts a
powerful influence on our behavior, he believed that unconscious
holds more than our repressed thoughts and feelings. He criticized
Freud’s theory of the Oedipus complex and his emphasis on
infantile sexuality. He said we all have a collective unconscious, a
storehouse of repressed memories sp ecific to the individual and our
ancestral past. This is a level of unconscious shared with other
members of the human species comprising latent memories from
our ancestral and evolutionary past. ‘The form of the world into
which [a person] is born is alre ady inborn in him, as a virtual image’
(Jung, 1953, p. 188). Jung called these ancestral memories and
images that have universal meaning across cultures as archetypes.
These archetypes show up in dreams, literature, art or religion.
These past experiences explain why people in different cultures
share certain myths and images, e.g., mother as a symbol of
nurturance, or f ear of the dark, or of snakes and spiders.munotes.in

Page 107

107Alfred Adler:
Alfred Adler had struggled to overcome his own childhood
illnesses and accident s due to which he had suffered from
inferiority complex. So, while proposing the concept of inferiority
complex he stated that e verybody experiences sense of inferiority,
weakness and helplessness as a child and struggle to overcome
the inadequacies by bec ome superior and powerful adults. He
identified ‘striving for superiority’ as a thrust propelling thought,
feelings, and actions of humans. Two important concepts in his
theory are: Parenting and Birth Order . According to Adler, the order
in which person i sborn in the family innately influences persons
personality. The first born , experience crisis as the attention shifts
to younger sibling after their births and to overcome this they
become overachievers. Middle born children are not pampered but
get the attention and become more superior. After dethroning older
sibling, they have power over their younger siblings and engage in
healthy competition. The youngest children have the least amount
of power in family and are more pampered and protected. This
crea tes a sense that they cannot take responsibilities and feel
inferior to others.
Adler identified two Parenting Styles that leads to problems
inadulthood: Pampering and Neglect .Pampering parents
overprotect a child, provide excessive attention, and prot ect from
the dark part of life. As adults, child has poor skills to deal with
realities, self -doubts about abilities. A Neglecting Parent do not
protect child at all, and they are left to deal with life problems alone.
As adults, they fear the world, canno t trust others, and have trouble
in developing close relations.
Karen Horney:
Karen Horney differed from Freud on his masculine focus
and idea of ‘penis envy’ and women having weak superego. She
substituted the concept of ‘penis envy’ with her idea of ‘ womb
envy’. She said that “The view that women are infantile and
emotional creatures, and as such, incapable of responsibility and
independence is the work of the masculine tendency to lower
women’s self -respect”. She considered the basic anxiety, a feelin g
of fearfulness and anxiety experience in childhood triggers the
desire for love and security.
Post Freud’s life, most contemporary psychodynamic
theorists and therapists do not accept the idea of sex as the basis
of personality. They do not accept the idea of id, ego and superego
and do not classify their patients in terms of ora l, anal or phallic
characters. B ut they do accept that much of our mental life is
unconscious, that very often we struggle with inner conflicts among
our wishes, fears and valu es and that our childhood experiences
shape our personality and the way we become attached to others in
later life.munotes.in

Page 108

108Neo-Freudians’ major disagreements with Freud can be
summarized as -
1.Socio cultural factors determine conflicts, not instincts.
2.Infantile sexuality is of little importance compared to socio -
cultural factors. Conflicts can be or are predominately non -
sexual.
3.Societal factors cause anxiety, not a defense.
4.Dreams have no latent content: could be metaphorical
expressions of the patient’s re al concern or reflect struggles to
achieve self -awareness and responsibility.
5.Oedipal complex has no sexual component, is due to
interpersonal/ social factors.
6.Technique of treatment: normally emphasize ‘here and now’,
de-emphasis on past, gaining insight etc.
6.2.3Assessing Unconscious Processes:
To peep into unconscious mind, early childhood experiences
and to unearth hidden impulses and conflicts, psychologists have
developed certain tools that do not ask direct questions and expect
answers in yes -noor true -false format as objective assessment
tools do. These tools that measure personality indirectly are known
as projective tools. Projective tests are like “psychological X -ray” in
which a test taker is asked to tell a story or describe an ambiguous
stimulus. It is assumed that any hopes, desires and fears that test
taker sees in the ambiguous image are the projections of their own
inner feelings or conflicts. One of these projective tests is
Rorschach Inkblot Test:
People are presented a series of 10inkblots printed on cards
and people are asked to describe what they see in these inkblots.
The test has been criticized on various counts. For instance, some
clinicians believe in the power of Rorschach test so much that they
have used it to assess cri minal’s violence potential and present it to
court as evidence. Others consider it as a helpful diagnostic tool, an
icebreaker and a revealing interview technique. However, the
scoring and interpretation of the test had been criticized often and
to overcom e this criticism a research based, computerized tool has
been designed to bring uniformity in scoring and interpretation. Yet
many critics comment that only some of Rorschach based scores,
such as scores for hostility and anxiety, have shown validity. So
these tests are not reliable as a whole. Other critics believed that
this test diagnoses many normal people as pathological as
clinician’s interpretations of the answers given are based on
intuitions of the clinicians.munotes.in

Page 109

1096.2.4 Evaluating Freud’s Psychoan alytic Perspective and
Modern Views of the Unconscious:
Recent research disagrees with Freud’s ideas on many
counts. For instance -
1.Modern developmental psychologists believe that development
is a lifelong process and not fixed in childhood only as Freud
believed.
2.They do not believe that an infant’s neural networks are mature
enough to hold as much emotional trauma as Freud assumed
that they do.
3.Some critics think that Freud overestimated the parental
influence and underestimated the peer influence.
4.Freud’ s idea that conscience and gender identity develops when
children resolve Oedipus complex at the age of5 or 6 was also
criticized. It is observed that children develop their gender
identity much earlier than age of 5 or 6 and become strongly
masculine or f eminine even without a same sex parent present.
5.Critics also believe that Freud’s ideas about childhood sexuality
arose from his skepticism of stories of childhood sexual abuse
told by his female patients. He attributed these stories of
childhood abuse to their own childhood sexual wishes and
conflicts.
6.Freud is also criticized on his methodology of collecting
information. The way he framed his questions might have
created false memories of childhood sexual abuse.
7.New ideas about why we dream are also con trary to Freud’s
belief that dreams display hidden feelings and are tools for wish
fulfillment . Similarly, slips of the tongue can be explained as
competition between similar choices in our memory. When
someone says that “I don’t want to do it -it’s a lot of brothel” may
simply be blending bother and trouble.
8.Freud’s idea that defense mechanisms disguise sexual and
aggressive impulses, and suppressed sexuality causes
psychological disorders, is also not supported by modern
research. From Freud’s time, our s exual inhibitions have gone
down but psychological disorders have not gone down.
9.Psychoanalytic theory assumes that the human mind often
represses troublesome wishes and feelings, banishing them into
the unconscious mind until they resurface. He believed that if
we can recover and resolve childhood’s conflicts and wishes,
emotional healing would follow. However, modern researchers
believe that repression is a rare mental response to trauma.
Even those who have witnessed a parent’s murder or survived
Nazi d eath camps retain their unrepressed memories of the
horror. (Helmreich 1992; Pennebaker,1990)munotes.in

Page 110

11010.It is also argued that Freud’s theory does not meet the criteria of
being scientific theory. A scientific theory must offer new
testable hypotheses and objective way of testing the existing
theory.
11.The most serious problem with Freud’s theory is that it offers
after -the-fact explanations of any characteristic but fails to
predict such behaviors and traits, e.g., according to his theory, if
you feel angry at your m other’s death, it is because your
unresolved childhood dependency needs are threatened. On
the other hand, if you do not feel angry, it is because you are
repressing your anger. Lindzey (1978) rightly commented that it
is like betting on a horse after the race is over.
12.Critics said that a good theory should give testable predictions
but Freud’s supporters said that Freud never claimed that
psychoanalysis was a predictive science. He m erely claimed
that looking back, psychoanalyst could find meaning in our state
of mind.
13.His supporters further point out that some of Freud’s ideas are
everlasting, e.g., he drew attention to the idea of unconscious,
irrationality, self -protective defense mechanisms, importance of
sexuality, tension between our biological impu lses and our
social well -being. He challenged our self -righteousness,
punctured our pretensions and reminded us of our potential for
evil.
6.2.5 The Modern Unconscious Mind
Modern researchers agree with Freud that we have very
limited access to all that goes on in our minds, but they think
unconscious does not comprise of just seething passions and
repressive censorings, rather there is information processing going
on there without our awareness. This infor mation processing can
involve:
a.)Formation of th e schemas that automatically control our
behavior
b.)The implicit memories that operate without conscious recall,
even among those with amnesia.
c.)The emotions that activate instantly, before conscious analysis.
d.)The formation of self -concept and stereotypes tha t
unconsciously influence the way we process information about
ourselves and others.
So, our lives are guided by off -screen, out -of-sight,
unconscious information processing. The unconscious mind is
huge.munotes.in

Page 111

111Recent research also supported Freud’s idea of defense
mechanisms. People tend to see their own faults and attitudes in
others. Freud called this tendency as ‘Projection ”,ad e f e n s e
mechanism. Modern researchers call it “False Consensus Effect”,
the tendency to overestimate the extent to which others share our
beliefs and behaviors. For example, people who break traffic rules
assume that everyone does it, people who are happy, kind and
trustworthy assume all others are also have same attributes.
Similarly, another defense mechanism used by people to d efend
their self -esteem is Reaction formation. Baumeister stated that
defense mechanisms are less likely to be used by seething
impulses and more by our need to protect our self -images.
Modern research has supported Freud’s idea that we
unconsciously de fend ourselves against anxiety. Greenberg et.al.
(1997) rightly said that one source of anxiety is “the terror resulting
from our awareness of vulnerability and death”. Terror management
theory shows that death anxiety increases contempt for others and
esteem for oneself (Koole et.al.,2006). Living in a threatening world,
people tend to act not only to enhance their self -esteem but also to
stick strongly to worldviews that answer questions about life’s
meaning. For example, the likelihood of death increases religious
sentiments and deep religious beliefs enable people to be less
defensive (Jonas & Fishcher,2006). When faced with death, people
yearn for and stick to close relationships, e.g., when a person is
nearing his end, he/she yearns to meet family and friends, and put
in extra efforts to reach out to them even if they have not
communicated before for years together.

1126.3HUMANISTIC THEORIES
By 19 50s and 19 60s, some personality psychologists were
dissatisfied with Freud’s deterministic and B. F.Skinner’s
mechanistic explanation of personality. They objected to Freud’s
ideas that human behavior is determined by forces beyond our
control, that human beings are basically evil and would destroy
themselves if not restrained by social norms which are internalized
in the form of superego. Moreover, Freud’s theory was developed
on the basis of motives reported by sick people. On the other
hand, Skinner vi ewed human personality through respond -reward
prism and emphasized only on learning. He considered human
beings like machines, where they respond to environmental inputs
on the basis of reward or punishment received in the past. They felt
that these theori es ignored the qualities that make humans unique
among animals. Two psychologists, Abraham Maslow and Carl
Rogers, became well known for their humanistic theories.
Humanistic theorists focused on the ways ‘healthy’ people strive for
self-determination and self-realization and offered a ‘third force’
option that emphasized human potential
6.3.1Abraham Maslow’s Self -Actualizing Person :
Maslow developed his theory based on healthy, creative
people rather than troubled clinical cases. He proposed that we a re
motivated by a hierarchy of needs. First, we are motivated to satisfy
our physiological needs followed by safety needs, then need to be
loved or belong and then self -esteem and finally self -actualization
and self -transcendence. Self -actualization refers to a process of
fulfilling our potential and self -transcendence refers to searching
meaning, purpose and communion beyond the self.
He based his study of self -actualization on the basis of
studying people like Abraham Lincoln, who were known for their
rich and productive lives. Maslow stated that such people share
certain similar characteristics. They are more self -aware, self -
accepting, open and spontaneous, loving and caring and not stuck
by their own opinions. While working with college students, Mas low
said that those who will become self -actualizing adults later on are
the ones who are likeable, caring, privately affectionate to their
elders and secretly uneasy about the cruelty, meanness and mob
spirit.
Maslow's self -actualizing characteristics :
Efficient perceptions of reality :Self-actualizers are able to
judge situations correctly and honestly. They are very sensitive
to the fake and dishonest, and are free to see reality 'as it is'.munotes.in

Page 113

113Comfortable acceptance of self, others and nature :Self-
actualizers accept their own human nature with all its flaws. The
shortcomings of others and the contradictions of the human
condition are accepted with humor and tolerance.
Reliant on own experiences and judgment: Independent, not
reliant on culture and en vironment to form opinions and views .
Spontaneous and natural :True to oneself, rather than being
how others want. They have outgrown their mixed feelings
towards their parents, have found their ultimate goals, have
enough courage to be unpopular, to be unashamed about being
openly virtuous.
Task centering :Since they are secure in their sense of who
they are, their interests are problem -centered and not self -
centered. They focus their energies on a particular task and
make that task as the mission of th eir lives. Most of Maslow's
subjects had a mission to fulfill in life or some task or problem
'beyond' themselves to pursue
Autonomy :Self-actualizers are free from reliance on external
authorities or other people. They tend to be resourceful and
independ ent.
Continued freshness of appreciation :The self -actualizer
seems to constantly renew appreciation of life's basic goods. A
sunset or a flower will be experienced as intensely time after
time as it was at first. There is an "innocence of vision", like t hat
of an artist or child.
Profound interpersonal relationships :The interpersonal
relationships of self -actualizers are marked by deep loving
bonds.
Comfort with solitude :Despite their satisfying relationships
with others, self -actualizing people value solitude and are
comfortable being alone.
Non-hostile sense of humor :This refers to the ability to laugh
at oneself.
Peak experiences :All of Maslow's subjects reported the
frequent occurrence of peak experiences (temporary moments of
self-actualization). These occasions were marked by feelings of
ecstasy, harmony, and deep meaning. Self -actualizers reported
feeling at one with the universe, stronger and calmer than ever
before, filled with light, beauty, goodness, and so forth.munotes.in

Page 114

114According to Maslow, peak experiences are "Feelings of
limitless horizons opening up to the vision, the feeling of being
simultaneously more powerful and also more helpless than one
ever was before, the feeling of ecstasy and wonder and awe,
the loss of placement in time and space with, finally, the
conviction that something extremely important and valuable had
happened, so that the subject was to some extent transformed
and strengthened even in his d aily life by such experiences." In
other words, these are moments of transcendence in which a
person emerges feeling changed and transformed.
Socially compassionate: Possessing humanity. They are
emotionally mature and have learned enough about life so that
they are compassionate towards others.
Few friends :They have f ew close intimate friends rather than
many superficial relationships.
6.3.2 Carl Rogers’ Person -Centered Perspective :
Carl Roger also believed that people are basically good and
areendowed with self -actualizing tendencies. Unless faced with an
environment that hinders growth, each of us is like a fruit, ready for
growth and fulfillment .R o g e rb e l i e v e dt h a tg r o w t hp r o m o t i n g
climate needs to fulfil lthree conditions:
1.Genuineness :G e n u ine people are open with their feelings,
drop their pretentions or deceptive outward appearance, are
transparent and self -disclosing.
2.Acceptance: When people are accepting, they offer
unconditional positive regard, an attitude of grace that values us
even knowing our failings. It is a great relief to drop our
pretentions, confess our worst feelings, and discover that we
are still accepted, that we are free to be spontaneous without
feeling the loss of others’ esteem.
3.Empathy: Empathic people share and mir ror other’s feelings
and reflect their meanings.
Rogers believed that genuineness, acceptance and empathy
are like water, sun and nutrients that help us to grow like a fruit. As
people are accepted and prized, they tend to develop a more caring
attitude toward themselves. When people are heard emphatically, it
becomes possible for them to listen more accurately to the flow of
inner experiencing . Unconditional love makes a person optimistic,
enthusiastic and helpful. For Carl Rogers and Maslow, the centr al
figure of personality is self -concept. Self-concept refers to all the
thoughts and feelings that one has in response to a question -Who
am I? If self -concept is positive we view the world positively and ifmunotes.in

Page 115

115we have negative self -concept, we view the world negatively and
we will feel dissatisfied and unhappy.
6.3.3Assessing the Self:
To measure personality, humanistic psychologists ask
people to fill out a questionnaire that would evaluate their self -
concept. The questionnaire has questions asking peopl et o
describe themselves both as they would ideally like to be and as
they actually are. Rogers said that the self -concept will be positive
when ideal self and real self are nearly alike.
Some humanistic psychologists believe that using a
standardized as sessment tool such as questionnaire, to measure
personality is depersonalizing. Instead of forcing a person to
respond to narrow categories, it is better to use tools like interviews
and intimate conversations for a better understanding of each
person’s un ique experiences.
6.3.4Evaluating Humanistic Theories:
Just like Freud, Maslow and Carl Rogers also have had a
tremendous impact on other psychologists. Their ideas have
influenced counseling, education, child -rearing, and management.
Unintendedly, th ey have also influenced today’s popular
psychology. But there has been some criticism for humanistic
theories.
1.Humanistic psychology believes in tenets such as positive self -
concept is key to happiness and success, a cceptance and
empathy nurture positive feelings about oneself, people are
basically good and capable of self -improvement, humans are
basically rational, socialized and forward moving (striving to be
better ),humans are constructive, trustworthy, and congruent
when they are free of defensivenes s.These ideas are well
accepted in western cultures but not in all cultures.
2.Critics are of the opinion that humanistic theories are vague and
subjective. For example, Maslow’s description of self -actualizing
people as open, spontaneous, loving, self -accepting and
productive is not a scientific description. This description is
merely a description of Maslow’s own values and ideals, an
impression of his personal heroes. However, if another theorist
has another set of heroes such as Napoleon or Margaret
Thatcher, he would probably describe self -actualizing people as
“undeterred by others’ needs and opinions”, “motivated to
achieve”, and “comfortable with power”. (M. Brewster
Smith,1978) . In other words, subjective ideas such as authentic
and real experienc es are difficult to objectify; an experience that
is real for one individual may not be real for another person.munotes.in

Page 116

1163.Humanistic psychology is not a true science because it involves
too much common sense and not enough objectivity.
Humanistic concepts are dif ficult to define operationally and test
scientifically. These theories have been criticized for merely
describing personality, rather than explaining it
4.Critics also objected to the idea that put by Rogers that the only
thing that matters is the answer to a question, “Am I living in a
way which is deeply satisfying to me, and which truly expresses
me?” Critics said that this encouragement on individualism in
humanistic psychology can be detrimental. Emphasizing on
trusting and acting on one’s feelings, bei ng true to oneself,
fulfilling oneself can lead to self -indulgence, selfishness, and an
erosion of moral restraints. Those who focus beyond
themselves are most likely to experience social support, enjoy
life and cope effectively with stress. However, human istic
psychologists defended themselves by saying that a secure,
non defensive self -acceptance is the first step towards loving
others. If people don’t love themselves, how can they love
others.
5.There are those who believe humanistic theory falls short i ni t s
ability to help those with more sever personality or mental health
pathology. While it may show positive benefits for a mino r
issue, using the approach of R ogers to treat schizophrenia
would seem ludicrous.
6.Critics also say that humanistic psycholo gy is naïve, i.e., lacking
wisdom. It fails to appreciate the reality of our human capacity
for evil. We are living in a world where we are facing the
challenges of climate change, overpopulation, terrorism and the
spread of nuclear weapons. In such a situ ation, it is most likel y
that we may lose optimism that denies the threat and we may
drown in dark despair where we think it is hopeless to try to
change the situation. Critics say that humanistic psychology
does encourage the hope that is needed for takin g action but it
does not provide equally necessary realism about the evil and
how to cope with it.

1176.4 SUMMARY
In this unit, we have discussed various theories of
personality. We began with Freud’s theory of psychoanalyses in
which he had explained the division of mind, personality structure
divided into three parts –id, ego and superego, five psychosexual
developmental stages of personality –oral, anal, phallic latency and
genital stage, and based on the conflicts and anxieties faced during
these developmental stages, people use various defen se
mechanisms such as projection, reaction formation, denial,
regression, rationalization and displacement. These defense
mechanisms can be useful to alleviate anxiety, only if they are used
in moderation. If they are used in excess they can lead to
maladj ustment.
However, Freud’s theory has been criticized on various
counts by Neo -Freudians as well as Humanistic psychologists.
Though Neo -Freudians could not shake themselves away from
Freud’s ideas completely but they significantly held different views .
They said that they don’t completely agree with Freud’s idea that
sexuality explains everything .T h e ye i t h e rm o d i f i e d ,e x t e n d e do r
revised Freud’s original psychoanalytic theory and emphasized the
role of social, cultural and interpersonal factors also i ns h a p i n gt h e
personality. Some of the most well known Neo -Freudians are Alfred
Adler, Karen Horney and Carl Jung. While Freud assumed that
people have no choice in shaping their personality, Adler believed
that people are largely responsible for who they are and they are
driven by need reduce inferiority complex. Freud assumed that
present behavior is caused by past experiences while Adler
believed that present behavior is shaped by people’s view of the
future. Unlike Freud’s emphasis on unconscious mind, Adler
believed that psychologically healthy people are usually aware of
what they are doing and why they are doing it.
Horney objected strongly to the concept of “penis envy” ,
Oedipus complex, lack of confidence and an overemphasis on love
relationships ,andsaid that personality development has got very
little to do with the anatomy of sex organs. She also believed that
aggression is not inborn, but humans try to protect themselves by it.
Similarly, she did not believe that conflict is inbuilt in human nature,
rather she felt that it arises from social conditions.
Carl Jung also objected to the idea of Oedipus complex and
infantile sexuality and emphasized on collective consciousness.
Maslow and Carl Rogers emphasized on looking at healthy
and succe ssful individuals while framing the tenets of personality
theory and emphasized that human beings are inherently directedmunotes.in

1207.1 INTRODUCTION
In the last unit, we have discussed some approaches to
understand personality. In this unit, we are going to explore Trait
Perspective, social cognitive approach to personality and we will be
looking at self in detail. We will se e how self -esteem is beneficial for
us and how self -serving biases influence our behavior. We will also
see how biology is linked to personality.
7.2 TRAIT THEORIES
7.2.1 E xploring and assessing traits
Instead of focusing on unconscious forces and ham pered
growth opportunities Trait theorists define personality in terms of
traits -traits , which can be defined as habitual patterns of behavior,
thought, and emotion. Traits are relatively stable over time, differ
across individuals (e.g. some people are outgoing whereas others
are shy), and influence behavior.
The seed of this approach was sown when in 1919, Gordon
Allport, a young psychologist met Sigmund Freud, a renowned
psychologist of that era, out of curiosity. During that meeting, Freud
kept tryi ng to find out what were Allport’s hidden motives behind
that meeting . That experience led Allport to describe personality in
terms of traits. He was not interested in explaining the individual
traits, rather he was more interested in describing these trai ts.
Exploring traits:
Each of us are a unique combination of multiple traits. The
question arises which trait dimensions describe personality. Allport
and Odbert (1936) counted all the words in a dictionary with which
one could describe people. There were almost 18000 such words.
It was necessary for psychologists to condense this list to a
manageable number of basic traits. To achieve that they used a
statistical technique called factor analysis.
Factor Analysis: It is a statistical procedure used t oi d e n t i f y
clusters of test items that represent basic components of a given
trait. For example, people who describe themselves as outgoing
also tend to like excitement and practical jokes and dislike quiet
reading. Such a statistically correlated cluster of behaviors
indicates a basic trait, in this example it is extraversion.munotes.in

Page 121

121Fig.7.1
Hans Eysenck and Sybil Eysenck believed that by using
factor analysis, we can reduce many of our normal individual
variations to two or three dimensio ns such as extraversion -
introversion and stability -instability. (Fig. 7.1)
Biology and Personality: There are many traits and mental states
such as extraversion, intelligence, impulsivity, addictive cravings,
lying, sexual attraction, aggressiveness, empa thy, spiritual
experiences, racial and political attitudes, etc. that can be studied
with brain -imaging procedures. For example, studies using brain
imaging indicate th at extraverts seek stimulation because their
normal b rain arousal is relatively low and frontal lobe area involved
in behavior inhibition is less active in them.
Similarly, studies have shown that our genes also
significantly influence our temperament and behavioral style. For
example, Kagan attributed differences in children’s shyness and
inhibition to their autonomic nervous system reactivity. If we have
highly reactive autonomic nervous system, we respond to stress
with greater anxiety and inhibition. On the other hand, the fearless,
curious child may become the rock climbing or fast -driving adult. It
has been found that not only humans but even animals have stable
traits that shapes their personalities and by selective breeding,
researchers can produce bold or shy birds.
Assessing Traits:
Once it was established that stable traits in fluence our
behavior, the next question was how to measure these traits in
most reliable and valid way. Many trait assessment techniques
have been devised , such as personality inventories .Personality
inventories are longer questionnaires covering a wide r ange of
feelings and behaviors, i.e., they assess many traits at once. Some
of these personality inventories are -
munotes.in

Page 122

122MBTI: Myers and Briggs devised a questionnaire with 126
questions based on Carl Jung’s personality types. This
questionnaire is known as Mye rs-Briggs Type Indicator(MBTI). It is
available in 21 languages and is used mostly for counseling,
leadership training, and work -team development. It counts the test -
taker’s preferences, labels them as indicating “feeling type” or
“thinking type” and gives feedback to the test -taker in
complimentary terms. For example, feeling type are told that they
are sensitive to values, sympathetic and tactful, while thinking type
are told that they prefer an objective standard of truth and are good
at analyzing. Each type has its strengths, so everyone is affirmed.
Though this test is popular in business and career counseling but it
is not a good predictor of job performance.
Minnesota Multiphasic Personality Inventory ( MMPI ):This test
was developed by Starke Hathaw ayet.al. ( 1960) originally to
assess “abnormal” personality tendencies such as emotional
disorders, but now it is used for many other screening purposes ,
such as work attitudes, family problems, and anger .
To construct this test, t he MMPI items (questi ons) were
empirically derived. Hathaway et.al. initially gave hundreds of true -
false statements to groups of psychologically disordered patients
and normal people. From a large collection of items, they retained
only those questions on which both groups di ffered significantly .
Then these questions were grouped into 10 clinical scales such as
scales measuring depressive tendencies, masculinity -femininity,
and introversion -extraversion.
Personality inventories are better measure of personality
than project ive tests discussed in previous unit, because projective
tests have subjective interpretation while personality inventories
can be scored objectively. In fact, so objectively that a computer
can administer and score them. Yet these personality inventories
do not guarantee high validity. For instance, people taking MMPI for
employment purpose may not give truthful answers and may give
socially desirable answers to create a good impression on the
tester. To overcome this problem the MMPI has a lie scale and
those who are not being very truthful may get high lie score
revealing to the tester that test -taker has faked his answers. The
objectivity of the MMPI has made it more popular than many other
tests and it has been translated in more than 100 languages.
7.2.2 Thinking Critically about h ow to be a “successful”
Astrologer or Palm reader:
For centuries now, psychologists have been wondering, can
we predict personality traits, career of a person from his horoscope
or can we be assured that marriage based o n matching horoscopemunotes.in

Page 123

123will be successful and long -lasting. The answer to all these
questions is “NO”. Research has shown that matching the
horoscope is no guarantee that couple will be happy or well -
adjusted with each other or that their marriage will last.
Similarly, graphologists (who make predictions from
handwriting samples) have been found to be very often inaccurate
in judging people’s personality and occupation from their
handwritings. Yet, millions of people seek out these astrologers,
palm reader s and graphologists. The question arises how these
people are able to fool so many people?
Ray Hyman ( 1981), a palm reader turned research
psychologist revealed the tricks used by these people. Some of
these tricks or suckering methods are –
1.Stock Spiel : This method is based on the observation that
everyone in this world is different from everyone else and yet they
are very similar. Since we are similar to others in many ways, when
the astrologer/palm reader makes a generalized statement, it
appears to b e very accurate to the listeners. For example, he may
say, “I sense that you worry about things more than you disclose,
even to your best friends” or he may say, “I sense that you're
nursing a grudge against someone; you really ought to let that go"
or he may say, “you have a strong need for other people to like and
to admire you, you have a tendency to be critical of yourself….”,
etc. These are general statements that can be connected with
personality traits. People accept the generalizations that are tru eo f
nearly everybody to be specifically true of themselves.
2.Barnum Effect: People have the tendency to accept potentially
vague and over -generalized, unsupported information as true ,
especially if that information is flattering or favorable to them .T h i s
is called the Barnum effect. For several decades, psychologists
have investigated the ‘Barnum effect’ (sometimes known as the
Forer effect). This phenomenon occurs when people accept
personality feedback about themselves because it is supposedly
derived from personality assessment procedures. In other words,
people fall victim to the fallacy of personal validation. People accept
the generalizations that are true of nearly everybody to be
specifically true of themselves. For example, Davies(1997)
conducted an experiment, in which college students were given a
personality test and then given false, generalized feedback for the
test that they had taken. When that feedback was favorable and
were told that it was prepared just for them, the students always
rated that feedback as good or excellent. Studies show edthat
when favorable personality description was given as a feedback,
students who were initially doubtful about astrology were more
likely to accept the personality description as well as increase dtheirmunotes.in

Page 124

124belief in astrology as a whole. In other words, those for whom
astrological theory provide da more attractive self -portrait were
more likely to express belief in the validity of astrologers.
3.Read: Astrologers keep their eyes open. They a lso use their
other senses to judge a client on the basis of clothing, jewelry,
mannerisms and speech. For example, if they see a lady dressed in
expensive clothes longingly looking at the calendar on the wall with
a happy child’s photo , the astrologer can judge that lady is rich but
does not have or has lost a child of her own.
4.Tell them what they want to hear: Astrologers start with some
safe sympathy statements such as “I sense you are having some
problems lately. You seem unsure what to do….” Then tell them
what they want to hear. They memorize some Barnum statements
from astrology manuals and use them liberally.
5.Gain a client’s cooperation in advance: They tell clients it is
their responsibility to cooperate by relating astrologer’s message
with their specific expe riences. They emphasize that the success of
reading their palm or horoscope depends as much upon client’s
sincere cooperation as upon astrologer’s efforts. The clients will
connect those statements with their exper iences and later on they
will think that a strologer predicted those specific details.
6.Fishing: They use the technique of fishing -am e t h o df o r
getting the client to tell the astrologer about himself/herself. One
way of fishing is to phrase each statement in the form of a question.
Then wait fo r the client to reply (or react). If the reaction is positive
then the astrologer turns the statement into a positive assertion.
Very often the client responds by answering the implied question
and later forgets that he was the source of astrologer’s infor mation.
7.Good Listener: During the session, astrologer listen carefully to
hisclient and later on, in different words, reveal to client what the
client himself earlier revealed to the astrologer .He does not realize
that what astrologer is saying is exa ctly what hehad told the
astrologer a few minutes ago. So, the saying goes, if you dupe the
clients, they will come back. Another value of listening is that most
clients who seek the services of a reader actually want someone to
listen to their problems. In addition, many clients have already
made up their minds about what choices they are going to make.
They merely want support to carry out their decisions.munotes.in

Modern trait researchers believe that while simple trait
factors such as Eysenck’s’ introverted -extroverted and unstable -
stable dimensions are important but they do not cover the entire
personalit y. Costa & McCrae (2009) felt that a slightly expanded set
of factors, called the Big Five, does a better job of judging entire
personality. The Big Five is the most popular trait theory in
personality psychology in modern times, and since 1990s lot of
research is being carried out on this theory. These Big Five factors
are as shown in the above table.munotes.in

Page 126

126Research has explored various questions related to Big Five.
For example, psychologists wondered:
a.)How stable are these traits? Research shows that in ad ulthood,
these traits are quite stable, with some tendencies (such as
emotional instability, extraversion, and openness) decreasing or
even disappearing a bit during early and middle adulthood, and
some tenden cies (such as agreeableness and conscientiousne ss)
rising. Conscientiousness increases most during people’s 20s while
agreeableness increases during people’s 30s and continues to
increase through their 60s (Srivastava et.al.2003)
b.)Psychologists were curious to know whether these traits are
heritable. It is found that individual differences in each of Big Five
factors are attributable to genes up to 50% or little more. Many
genes combine to influence our traits. It is also found that certain
brain areas are also associated with the various Big Five trait s. For
example, frontal lobe area is sensitive to reward and is larger in
extraverts.
c.)Another question that psychologists asked was, do the Big Five
traits predict other behavioral attributes? T he answer is yes. For
example:
i)Shy introverts are more like ly than extraverts to prefer
communicating by e -mail rather than fa ce-to-face (Hertel
et.al.,2008)
ii)Highly conscientious people earn better marks . They are also
more likely to be morning type persons, that is, they get up early in
the morning and are fully alert and full of energy in the morning.
Evening types are more likely to be extraverted.
iii)People low on agreeableness, stability and openness are more
likely to suffer marital and sexual satisfaction.
iv)Big Five traits influence our written language use also. For
instance, in text messaging, extraverted people use more of
personal pronouns, people high on agreeableness use more of
positive emotion words, and those high on neuroticism ( emotional
instability) use more of negative emotion words.
7.2.4 Ev aluating Trait Theories:
The question arises whether research supports the
consistency of personality traits over time and across situations. Is
our behavior influenced by the interaction of our inner traits with
environment? If yes, which is more import ant–the traits or the
environment? Research shows that as people grow older their
personality traits stabilize. Their interests, careers, relationshipsmunotes.in

Page 127

127may change, but their personality traits do not change. It is also
empirically recognized that our tra its are socially significant. They
influence our health, our thinking and our job performance.
Longitudinal studies have shown that our mortality, divorce and
occupational attainment can be predicted on the basis of our
personality traits. Even though our personality traits are stable over
time and do influence our behavior, the specific behavior of the
people differs from situation to situation. People do not act with
predictable consistency. For example, a person will display much
more confidence, an outg oing social behavior in a familiar situation
when he is with his friends than when he is in unknown, hostile
circumstances. However, people’s average outgoingness,
happiness or carelessness over many situations can be predicted
(Epstein, 1983a,b).
Rese arch also shows that we do have genetically influenced
traits. And those traits remain in hidden form in our music
preference, our preferences in our personal space such as homes
or offices, familiar or unfamiliar, formal or informal situations,
personal w ebsites, and even e -mails. For instance, it is found that
in case of Music preference classical and folk music lovers tend to
be open to new experiences and have high verbal intelligence.
Religious music lovers tend to be cheerful, outgoing and
conscientio us (Rentfrow & Gosling, 2003,2006)
Personal Space –Our personal space shows our identity and
leaves a behavioral residue. A quick inspection of anyone’s room
can tell about that person’s conscientiousness, openness to new
experiences, and even emotional stability (Gosling et.al.2002,
2008).
Personal Website –Personal website or a Facebook profile of a
person can reveal that person’s extraversion, conscientiousness
and openness to new experiences. Even just pictures of people,
their clothes, expressions and postures can give us clues about
their personality (Naumann et.al. 2009).
E-mail –We can detect personality traits such as extraversion and
neuroticism, of people from the writing voice in their e -mails or
even blog writing. For example, extravert s use more of adjectives.
Unfamiliar, Formal Situations -When we visit as a guest, the
home of a person from another culture, our traits remain hidden as
we carefully attend to social cues. In familiar informal situations
such as just being with friends , we feel less restricted and allow our
traits to emerge (Buss,1989). In informal situation, our expressive
styles, our way of speaking and gestures are very much consistent.
For instance, Bella DePaulo et.al.(1992) conducted an experiment
to evaluate peop le’s voluntary control over their expressiveness.munotes.in

Page 128

128She ask participants to be either expressive or inexpressive while
stating opinions. She found that inexpressive people, even when
pretending to be expressive, were less expressive than expressive
people wh o were acting naturally. Similarly, expressive people
while trying to pretend to be inexpressive, were less inexpressive
than inexpressive people who were acting naturally. It shows that it
is difficult to be someone you are not or not to be who you are.
So, to summarize we can say that at any moment the
immediate situation ( especially strong situation) powerfully
influences a person’s behavior. For instance, while driving all
drivers will stop at red light irrespective of their personality traits.
But if we average our behavior across many situations, it does
reveal o ur distinct personality traits.
7.3SOCIAL COGNITIVE THEORIES
Social cognitive perspective on personality was proposed by
Albert Bandura. He said that just like nature and nurture always
work together similarly, individuals and their situations also work
together. Our behavior is influenced by our learning (social part
learnt through conditioning/observing/ imitating) and what we think
(mental process or the cognitive part) about the situa tion. It is the
way we interpret and respond to external events. Our schemas,
memories and our expectations influence our behavior patterns. So
let us see some of these influences.
7.3.1Reciprocal Influence:
Bandura viewed the person -environmental inter action as
reciprocal determinism .Aperson's behavior both influences and is
influenced by personal factors and the social environment ,e.g., a
child’s T.V. viewing habits(past behavior) influences his viewing
preference(an internal factor) which will infl uence how TV(an
environmental factor) affects his current behavior. These influences
are mutual. There are 3 specific ways in which individuals and
environments interact -
a.)Different people choose different environments : The kind of
programs you watch on TV , the kind of friends you choose,
music you listen to, etc. are all part of an environment you have
chosen based partly on your nature or personality. First you
choose your environment and then it shapes you.
b.)Our personalities shape how we interpret and react to
events: For example, anxious people are more receptive to
potentially threatening events. They perceive the world as
threatening and react accordingly.munotes.in

Page 129

129c.)Our personalities help create situations to which we react:
How we view and treat other people influences how they in turn
treat us. If we expect someone to ignore us, we may give that
person a cold shoulder, and in return that person may snub us
as we expected. On the other hand, if we have an easygoing
positive temperament, we are more likely to enjoy close,
supportive friendships. Thus, we are both the product and the
architects of our environment. Behavior is an interplay of
external and internal influences. See figure 15.2
Fig.7.2
7.3.2Personal Control:
Personal control refers t o whether we see ourselves as
controlling or being controlled by our environment. When we
believe that we control our environment it is known as internal locus
of control and when we believe that we are controlled by our
environment, it is called external locus of control. Let us see how
these beliefs affect us.
a)Internal vs. External Locus of Control :
Those who have internal locus of control believe that
whatever happens to them is chosen by them or is due to their
efforts. They believe that they are s uccessful due to their hard work
and not because of their fate. On the other hand, people with
external locus of control believe that whatever happens to them due
to their destiny or other external factors, they have no control over
them.
Research studi es have shown that people having internal
locus of control get better marks, are more independent, have
better health, are less depressed, and are better in delaying
gratification and coping with stressors including marital problems
(Miller & Monge,1986)Su ch people learn better, perform better at
work and are more helpful. Another study found that children who
expressed internal locus of control at the age of 10 had less
obesity, hypertension and distress at the age of 30.

130b)Depleting & Strengthening Sel f-Control:
Self-control refers to the ability to control impulses and delay
gratification. People with high self -control have good adjustment,
better marks and social success. Students who plan their day’s
activities and then stick that plan are less like ly to be depressed
later on. Baumeister & Exline (2000) held that self -control is like a
muscle. It temporarily becomes weak after exertion, gets strong
again after rest and becomes stronger with exercise. If we use
willpower, it temporarily uses up our me ntal energy needed for self -
control on other tasks. It even uses up blood sugar and neural
activity associated with mental focus. For example, experiments
showed that hungry people who had resisted the temptation to eat
chocolate biscuit gave up sooner on a tedious task later than those
who had not resisted and eaten chocolate biscuit. Similarly, people
who had used up their mental energy in trying to control their
prejudices were less restrained later in being aggressive in
response to provocations. They w ere less restrained in their
sexuality after spending willpower on laboratory tasks. However, it
was also found that their effortful thinking improved if they were
given energy -boosting sugar.
Self-control requires attention and energy. People who
pract ice self -regulation through physical exercise and time -
management develop self -regulation capacity. People with
strengthened self -control have better self -management in eating,
drinking, smoking and household chores (Oaten & Cheng,
2006a,b). In other words , if we develop self -discipline in one area of
our lives, this strengthened self -control spills into other areas of life
as well. We can grow our willpower muscle by using some
willpower.
c)Learned Helplessness vs. Personal Control :
People with externa l locus of control often feel helpless and
oppressed. This perception deepens their feeling of resignation. For
example, an elephant who had been shackled right from childhood
develops a feeling of helplessness and later on when it becomes
strong enough to break the chain and free itself, still does not do it
due to learned sense of helplessness. Similarly, among human
beings also, when people are repeatedly faced with traumatic
events over which they have no control, they start feeling helpless,
hopeless a nd depressed. This is called learned helplessness.
We feel shocked in an unfamiliar culture due to reduced
sense of control, we are not sure how others will respond to us.
People in prisons, factories, colleges and nursing homesmunotes.in

Page 131

131experience lower moral e and increased stress due to lack of control
over their environment. Studies showed that when prisoners were
allowed to move chairs and control room lights and TV, their health
and morale went up. Similarly, when factory workers were allowed
to participat e in decision making and were allowed to personalize
their workspace, their work engagement went up, and when
patients in nursing homes were offered choices about their
environment and allowed to exert more control over their
environment, it significantly improved their health and morale. They
became more happy, alert and active.
These studies showed that people thrive when they are
given personal freedom and empowerment. This is the reason why
people in stable democracies report higher levels of happines s. It
shows in their body language also, e.g., even poor people in
democracy feel empowered and often laugh more, sit upright rather
than slumped. However, Barry Schwartz (2000 ,2004) concluded
from his study that excess of freedom in today’s Western cultur es
leads to decreasing life satisfaction and increases depression and
sometimes decisional paralysis. For instance, research showed that
people express dissatisfaction when they choose jam or chocolate
out of 30 brands than those who choose jam/chocolate o ur of only
12 brands. The tyranny of choice brings information overload and
the chances are more that we will regret over some of the
unchosen options and feel dissatisfied.
d)Optimism vs. Pessimism:
Optimism and Pessimism refers to attributional style of the
people, their characteristic way of explaining positive and negative
events. For instance, if a student fails, he may attribute his failure to
his lack of ability or to situations that were beyond his control
(Pessimism). Such a student is more like ly to continue getting low
marks than those who adopt more helpful attitude that hard work
and good study habits and self -discipline can make a difference.
Similarly, in dating couples, optimists and their partners feel more
supported and satisfied with t heir relationships. Expect good things
from others and you will get what you expect is the assumption.
e)Excessive Optimism:
Though positive thinking is beneficial when we are faced
with difficulties in life, but realism is equally important. One shoul d
not be overly optimistic. Realistic anxiety over possible failure can
lead us to put in more energetic efforts to avoid such a failure. A
student who is realistically anxious about upcoming exam will study
more and make sure that he passes the exam compa red to a
student who is over confident and does not study much. Studies
have indicated that Asian American students show higher
pessimism than European -American students. That is why Asian
American students have higher academic achievements. To bemunotes.in

Page 132

132successf ul you need to have enough optimism to give you hope
that you can succeed and there should be enough pessimism to
prevent complacency. Remember the story of hare and tortoise.
Hare was too optimistic and very low on pessimism.
Excessive optimism can blin d us to real risks. This an
unrealistic optimism about future life events gets fueled by our
natural positive thinking bias. For example, most teenagers who are
rash drivers see themselves as less vulnerable to meet with the
accidents than other average te enager rash drivers. If we are
overconfident of our ability to control an impulse such as the urge to
smoke, we are more likely to expose ourselves to temptations, and
to fail. That is why, you must have often heard smokers to say
confidently,” there is no thing much to giving up smoking I have
done it many times”. Those who optimistically deny the power and
effects of smoking, get into failed relationships, outwit themselves
in many other ways and ring the truth of “blind optimism can be
self-defeating”.
People also show illusory optimism about their groups. For
example, in all IPL matches, we keep guessing that our cricket
team has better chance of winning than the other teams even
though other teams may be known to be strong. Even when we
ourselves are getting prepared to get feedback such as our results
from the exams given, we tend to assume that we will pass
irrespective of how did we fare in our exams. This is due to natural
positive -thinking bias. Similarly, when the match is coming to an
end, we ar e more doubtful of our team winning especially if our
team has been ahead than when our team was fairing worse than
the other team. Positive illusion also vanishes after a traumatic
personal experience. For example, Americans were living with
positive illu sion that terrorism will not touch their lives till 9/11
happened.
f)Blindness to One’s Own Incompetence:
It is rather ironic that most people are most overconfident
when they are most incompetent. Justin Kruger and David
Dunning(1999) said it takes c ompetence to recognize competence.
Our ignorance of what we don’t know helps in sustaining our
confidence in our own abilities. This ignorance about our own
abilities becomes part of our self -concept and then our self -
assessment also influences how we per ceive ourselves doing. So it
is important to ask someone else also to assess our competence
and predict our future performance. For example, if you want to
assess your leadership abilities, don’t assess yourself, ask your
batch mates to judge your leadersh ip abilities.munotes.in

Page 133

1337.3.3Close -Up: Toward a More Positive Psychology:
Martin E. P. Seligman (2004) has been proponent of positive
psychology. Positive psychology can be defined as The scientific
study of optimal human functioning. It aims to discover and promote
strengths and virtues that enable individuals and communities to
thrive.
Positive psychology is an umbrella term for the study of
positive emotions, positive character traits and enabling institutions.
a.)Positive emotion is a combination of sati sfaction with the past,
happiness with the present, and optimism about the future.
Seligman stated that happiness is a by -product of a pleasant,
engaged and meaningful life.
b.)The Positive character focuses on exploring and enhancing
creativity, courage, c ompassion, integrity, self -control,
leadership, wisdom and spirituality. Seligman stated that
positive psychology is about building not just a pleasant life, but
also a good life that engages one’s skills, and a meaningful life
that points beyond oneself.
c.)Positive groups, communities and cultures, seek to foster a
positive social ecology. This includes healthy families,
communal neighborhoods, effective schools, socially
responsible media and civil dialogue.
Positive psychologists hope that positive psy chology will be
able to build healthy minds and cure mental diseases. Just like
Humanistic psychology positive psychology also believes in
advancing human fulfillment but its m ethodology is scientific.
7.3.4Assessing Behavior in Situations :
Social cogni tive theories do not believe that future behavior
can be predicted by administering a personality test or through an
interviewer’s intuition. They believe that future behavior of a person,
in any given situation, can be predicted by looking at the person’s
past behavior patterns in similar situation, e.g., the best predictor of
future aggressiveness is past aggressiveness and the best
predictor of future job performance is past job performance. If it is
not possible to check the past performance of a person a to predict
his future performance, than we need to create an assessment
situation that simulates the task that a person will have to perform
on actual job. For instance, to assess a candidat e for spy mission,
The U.S. Army psychologists made candidates g ot h r o u g h
simulated undercover conditions. They tested their ability to handle
stress, solve problems, maintain leadership, and withstand intense
interrogation without blowing up their cover.munotes.in

Page 134

134This method is time consuming and expensive, but it
predicts f uture behavior more accurately. Seeing the success of
simulated method, similar method called assessment center had
been developed and is extensively used by military, educational
institutes and Fortune 500 companies.
7.3.5Evaluating Social -Cognitive Th eories:
Social cognitive theories are based upon psychological
research conducted in the field of learning and cognition. These
theories sensitize researchers to how situations affect and how
situations are affected by individuals.
Critics of social co gnitive theories however argue that these
theories give too much importance to situations and do not give
much attention to person’s inner traits. For instance, a person’s
unconscious motives, emotions, and general personality triats,
biologically influenc ed traits.
7.4 EXPLORING THE SELF
For more than a century now, psychologists have been
vigorously researching the concept of self. There are many studies
that have studied topics like self -esteem, self -disclosure, self -
awareness, self -schema, self -monit oring, etc. Even neuroscientists
have identified a central frontal lobe region in brain that gets
activated when people answer self -reflective questions related to
their personality traits. The self generates so much interest among
researchers because it is assumed that the self as an organizer of
our thoughts, feelings, and actions is the center of personality.
Possible selves: Hazel Markus et.al. proposed that when people
think about self, they think about their possible selves. Possible
selves include a person’s vision of the self that he dreams of
becoming, e.g., rich self, successful self, loved and admired self,
etc. as well as vision of self that he fears of becoming, e.g., the
unemployed self, lonely self, failed self, etc. Such possible selves
motivate people to set specific goals to be achieved and also to
muster up energy to work towards those goals.
Spotlight Effect: When we are self -focused, we easily tend to
assume that others are noticing and evaluating us, e.g., a
conservative lady, weari ng a swim suit for the first time feels self -
conscious and assumes that everybody in the swimming pool is
watching her. While in reality very few people may have noticed
her. There are very few people who notice any variations in our
appearance and perform ance (Gilovich et.al.,2002), our
nervousness, irritation or attraction. In fact, even when we make a
mistake such as wearing creaky shoes and reaching late for a
class, dropping books with a loud noise in library, the number ofmunotes.in

Page 135

135people who notice those blun ders are far less than what we
assume. If you know about this tendency of spotlight effect, it can
empower you. For example, if a public speaker understands that
his nervousness is not obvious to his audience, his speaking
performance will improve.
7.4.1The Benefits of High Self-Esteem:
Having high self -esteem can be advantageous . For instance ,
people with high self -esteem:
Have less sleepless nights
Do not easily give in to pressures to conform
Are more persistent at difficult tasks
Less shy, anxious and lonely.
Are much happier than others. If they feel bad, they believe that
they deserve better and make more efforts to repair their mood.
Effects of Low Self -esteem:
People with low self -esteem tend to be oversensitive and
judgmental (Baumgardner e t.al.1989). Even if people’s self -image is
temporarily deflated, they are more likely to belittle others or to
express heightened racial prejudice (Ybarra,1999).People with low
self esteem are insecure andoften become highly critical of others,
as if they want to impress others with their own brilliance
(Amabile,1983).
Maslow and Rogers proposed that a healthy self -image is
beneficial for our growth and happiness. If we accept ourselves as
we are, it is easier for us to accept others. If we belittle ours elves,
we tend to criticize and reject others also.
7.4.2Self-Serving Bias:
Carl Rogers (1958) stated that most of the people “despise
themselves, regard themselves as worthless and unlovable”. Mark
Twain seconded his opinion and said, “Noman, deep d own in the
privacy of his heart, has any considerable respect for himself”.
However, later research indicated exactly the opposite of Rogers’
and Mark Twain’s views. Research studies done on self -esteem
indicated that actually people have ag o o dr e p u t a t i o n of
themselves. E ven low scoring people responded in midrange of
possible scores, e.g., a low self -esteem person will respond to
statements such as “I have good ideas” by saying “I have
somewhat good ideas” while a person scoring high on self -esteem
will s imply say that “I have good ideas”. Modern psychologists
believe that people with low self -esteem also respond positively
about themse lves due to self -serving bias. Self -serving bias can be
defined as our readiness to perceive ourselves favorably ,accepti ng
more responsibility for success than failure, for good deeds than
bad.munotes.in

Page 136

136A self -serving bias is any thought or perception that is
distorted by the need to maintain and enhance self-esteem ,o rt h e
tendency to perceive oneself in an overly favorable manner.
Individuals tend to attribute their success to their own abilities and
efforts, but attribute their failure to external factors. When
individuals reject the validity of negative fee dback, focus on their
strengths and achievements but overlook their faults and failures,
or take more responsibility for their group's work than they give to
other members, they are protecting their ego from threat and injury.
These cognitive and percep tual tendencies perpetuate
illusions and error, but they also serve the self's need for esteem.
For example, a student gives credit to his own intelligence and
preparation when gets good marks in an exam ,b u ti fh eg e t sl o w
marks, he blames external factor s such as that the teacher did not
teach properly orteacher does not know how to teach or question
paper was not set properly, etc. Thus, he shows his self-serving
bias. Research s tudies have shown that s elf-serving bias plays a
dominant role in various s ituations, such as the workplace,
interpersonal relationships , sports, and consumer decisions ,d r i v i n g
behavior, etc .For instance, a driver will alway s say that I was
driving properly, it is the other driver who was rash and smashed
his car into mine, or that pedestrian was not looking carefully while
crossing the road.
Most people see themselves as better than average,
especially when the behavior is socially desirable. For example,
studies have shown that 90% managers and more than 90%
professors rate their performance as superior to that of their
average peers. Similarly, most business managers say that they
are more ethical than their average cou nterparts. This phenomenon
of overestimating self and underestimating others is more common
in western countries. It is less prevalent in Asian countries because
in Asian culture modesty is valued. It does not mean that it is totally
absent in Asian countr ies. Self -serving bias is a worldwide
phenomenon. Pronin (2007) commented that the irony is that most
of the people think that others suffer from self -serving bias and they
themselves are immune to it, but the reality is that all of us suffer
from self -serving bias. Daniel Gilbert (2006) rightly said that “ if you
are like most people, then like most people, you don’t know, you
are like most people…….one of the most reliable of these facts is
the average person doesn’t see herself as average”.
Some additio nal findings from res earch on self -serving bias
are:
a.)People remember and justify their past actions in self -enhancing
ways.
b.)People show an inflated confidence in their beliefs and
judgments .munotes.in

Page 137

137c.)In situations, where most of people behave in less desirable
manner, we overestimate how desirable we would act.
d.)People are quicker to believe flattering descriptions of
themselves rather than unflattering ones, and they are
impressed with psychological tests that make them look good.
e.)People tend to enhance their sel f-image by overestimating the
commonality of their weaknesses and by underestimating the
commonality of their strengths.
f.)We tend to believe that our contribution to our group task is
better than average. Since every member of the group believes
that his/he r contribution to group task is better than average,
group members’ self -contribution estimates are usually higher
than 100%.
g.)We display group pride, that means, that we have a tendency to
see our group as superior than others’ group.
The Dark Side of Self-serving Bias/ High Self -Esteem:
Self-serving bias can be a major root cause for conflicts in
interpersonal relationships or even at world forum, e.g., people tend
to blame their spouse for marital discord, or they arrogantly believe
and promote their ow n ethnic superiority (e.g., Nazis believed in
“Aryan Pride” and committed atrocities on Jews .)when their self -
esteem is threatened, people with large egos, not only run down
other people but also react violently. Self-serving biases have the
potential to initiate wars and can make ending war more difficult .
Self-serving bias is not restricted to adults only, one can see
these tendencies even in children. Most of the fights among
children take place, when children with high self -esteem face social
reject ion. Children with high self -esteem tend to be more
aggressive, when other children dislike them and that hurts their
ego. Similarly, teenagers or adults who have very high opinion
about themselves become potentially very dangerous if their ego is
deflated by an insult, e.g., if a boy with very high opinion about
himself proposes to a girl and girl out rightly rejects him and may
even insult him, he will be become potentially very dangerous for
that girl. Brad Bushman & Roy Baumeister ( 1998) called it “the dark
side of high self -esteem”. Their experiment showed that threatened
egotism, more than low self -esteem, inclines a person towards
aggression. When people are encouraged to feel good about
themselves when they have not earned it seems to create
problem s. Baumeister (2001) said, “Conceited, self -important
individuals turn nasty toward those who puncture their bubbles of
self-love”.
In western culture as well as in Asian culture, from 1980s
onwards, popular songs have been emphasizing that one should be
self-focused and should have high self -esteem to succeed in life.
Research shows that college going students are getting influencedmunotes.in

Page 138

138by these songs and their self -esteem has gone up several notches
but the adverse effect of increasing self -esteem is that p eople have
correspondingly gone down on empathy. People with high self -
esteem do not see things from others’ perspective or do not have
tender, concerned feelings for people less fortunate than them
(Konrath et.al. 2011) .
Jean Twenge (2006;2010) reported that modern generation
–generation Me shows more narcissism than previous generation.
Narcissists are people who believe they are superior than others or
that they are special people. Narcissism is closely related with
materialism, the desire to be famou s, inflated expectations, more
hookups with less committed relationships, more gambling and
more cheating. All these characteristics are on the rise in modern
generation as narcissism is rising.
Use of Self -Disparage:
The question arises that if self -serving bias is so common
then why do so many people undervalue themselves. Research
shows that people undervalu e themselves for four reasons:
a.)Sometimes self -directed put -downs are subtly strategic. They
extract reassuring comments from others, e.g., if s omebody
says “No one likes me”, the other person may respond by
saying, “But not everyone has met you”.
b.)Before a game or an exam, self -belittling statements prepare us
for possible failure. If somebody tells you that in an upcoming
game your opponent is avery strong one, then if you lose the
game, it does not hurt your ego. You blame your losing a game
to the unfairness of the competition that is superior strength of
your opponent. On the other hand, if you win the game, it
enhances your ego that in spit e of having a strong opponent you
have won the game.
c.)Self-disparaging comments such as “How could I be so stupid”
also helps you to learn from your mistakes.
d.)Very often, Self -disparagement is related to one’s old self.
When people asked to remember th eir really bad behaviors,
they recall things from long ago while good behavior is recalled
from recent past. For example, a person may say I used to
short -tempered when I was a teenager but now I have cooled
down as I have matured. Wilson &Ross(2001) righ tly pointed
out that people are much more critical of their distant past
selves than of their current selves -even when they have not
changed.munotes.in

Page 139

139While researchers acknowledge the dark side of self -serving
bias and self -esteem, they also point out that we have two types of
self-esteem having two distinct effects.
a.)Defensive self -esteem : It is fragile and focuses on sustaining
itself, which makes failures and criticism feel threatening. This
perceived threat leads to anger and disorders.
b.)Secure Self -esteem: It is less fragile and less dependent on
external evaluations. People with secure self -esteem feel
accepted for who they are and not for their looks, wealth or
acclaim. They are not under pressure to succeed and focus
beyond themselves. One can gain se cure self -esteem by losing
oneself in relationships and purposes larger than self.

7.5 SUMMARY
In this unit, we talk ed about how trait theories origina ted with
Allport’s meeting with Freud. Trait theorists had a herculean task of
reducing the list of thousands of traits describing human personality
into manageable basic traits. For this they used the method of
factor an alysis. We also looked at how our autonomic nervous
system and genes can influence our traits and shape our
personalities. The most popular trait theory now days is Big Five
that speaks of five traits that describes entire hue of personality.
While evaluat ing trait theories, we looked at the person -situation
controversy and found that both are important. Our personality
traits also influence our behavior in different situations and if
situation is very strong, then situation influences our behavior rather
than traits. Out of this controversy originated social cognitive
theories.
Social cognitive theories talked about reciprocal determinism
and personal control. In personal control, we talked about locus of
control, techniques to strengthen self -control, l earned helplessness
vs. personal control, pessimism and optimism and blindness to
one’s own incompetence.
We shortly touched upon on benefits of positive psychology
and the evaluation of social cognitive theories.munotes.in

Page 140

140While exploring the self we touched upon the benefits of self -
esteem and how self-serving bias protects our self -esteem.
However, there can be both advantages and disadvantages of self -
serving bias. It can make us narcissist if overused and it can protect
our ego if we use self -disparage.

8.1 INTRODUCTION
Statistics and Psychology are intimately connected.
Psychology is research oriented. Research requires application o f
statistical knowledge to summarize the data and to draw certain
valid inferences or conclusions. Statistics deals with the method ofmunotes.in

Page 142

142collecting, organizing, classifying, analyzing and interpreting
numerical data. Statistics is divided in to broad fields: Descriptive
Statistics and Inferential Statistics. In this unit, wewould discuss
the uses of Statistics for Psychologists. Following this we would
discuss the Descriptive and Inferential Statistics and topics
associated with it.
8.2 WHY DO PSYCHOLOGISTS USE STATISTICS?
Psychologists use statistics for multiple purposes. Some of
which are briefly outlined below:
1.Knowledge of statistics helps us in our understanding of issues
related to applied and theoretical research .
2.Statistics helps us to summarize the data so as to study the
patterns in the given data. The branch of statistics that deals
with organizing numbers and summarizing them so that patterns
can be determined is called as Descriptive Statistics.
3.Statistics helps us to make scientific interp retations and draw
valid inferences. The field of statistics which deals withdrawing
valid and scientific inferences is called as Inferential Statistics.
4.Knowledge of Statistics helps in measuring / quantifying human
characteristics or abilities.
5.Statisti cs is of great use in identifying the general pattern of the
set of scores. Besides identifying we can also tabulate and
make graphic representations of the sets of scores (e.g.,
Results of Students in a given class for Example XII).
6.It gives an idea as t o how each individual’s own performance in
each area compares with his performance in other areas. For
e.g., how has Meena done in Paper IV as compared to Paper V.
This going togetherness is known as a measure of correlation.
7.Distribution of scores, also, tells us something about the test or
the question paper. For e.g.: Are the scores evenly distributed,
too easy or too difficult or do they vary uniformly or differently.
8.It can help usto get the standing of each individual, to see how
he/she has perform ed on each test. This requires a common
yardstick to express performance in two different areas.
9.Statistics gives an idea about the average level of a group,
makes comparison possible, and gives the typical level of
performance in the group. For e.g., how have the 8thstandards
done on the Math 'st e s t ?munotes.in

1438.3 DESCRIPTIVE STATISTICS: FREQUENCY
DISTRIBUTIONS
Descriptive Statistics refers to various methods of
organizing ,summarizing , and presenting data in an informative
way. Descriptive Statistics is that st atistics that is used to describe
thegiven data in a summarized manner. We can summarize the
data by using either the numerical method or the graphic method.
Descriptive Statistics includes the following:
a.Frequency Distribution, histogram and Frequency P olygon, the
normal curve and other distribution types.
b.Measures of Central Tendency (i.e., Mean, Median, Mode).
c.Measure of Variability (Range, Quartile Deviation, Average
Deviation, and standard Deviation).
d.Measure of Relationships.
However, in this par t of the unit we are focusing only on
Frequency Distribution and related concepts.
8.3.1Frequency Distribution :
A frequency Distribution is a method of presenting the data
in a summarized form. Frequency distribution can be constructed
by determining how often (with what frequency) various scores
occur. The other way is to set up the categories or classes and
check the occurrences of scores in each category or class. Some
frequency distribution tables include an extra column that shows
the percentage o f cases in each category. Frequency distributions
arepresented as frequency tables, histograms or polygons.
The advantages of using frequency distribution are:
1.Frequency tables help in organizing raw data in such a way that
information makes sense at a glance.
2.Frequency tables can help to identify obvious trends within a
data set and can be used to compare data between data sets of
the same type.
3.Frequency tables are easy to interpret and they can display a
large data sets in a fairly concise manner.
4.Frequency tables are used to present a frequency distribution
visually, with graphs.
Let us see an example of how frequency distribution table
looks for students scoring marks on psychology testmunotes.in

1458.3.2 Histogram:
Histogram is a graph that represents the class frequencies in
a frequency distribution by vertical adjacent rectangles. It is the
most widely used methods of a frequency distribution. The purpos e
of a histogram is to show the frequencies within class graphically.
In a histogram, it is assumed that scores be spread uniformly over
their intervals. The frequencies within each class interval of a
histogram are represented by a rectangle. The base of which
equals the size of the class interval and the height of which equals
the number of scores (f) within that interval.
The histogram has following special features:
1.Thearea of the histogram corresponds to the total (N) of the
distribution
2.The area of each bar in a histogram corresponds to the
frequency within a given interval.
3.Theclass intervals shown at the x axis in histogram do not have
any gaps. They are continuous and always touch .F o re x a m p l e ,
if we want to draw a histogram of above table, then on x axis,
for class interval 50 -59 we will begin with 49.5 -59.5, then 59.5 -
69.5 and so on.
4.The bars are always vertical.
To plot a histogram the first step is to create a frequency
table. Let us take an example to plot a histogram from the following
frequency table

8.3.3 Frequency Polygon:
A frequency polygon is a lso a graph ical presentation of
frequency distribution. It is a line graph showing a frequency
distribution. The basic difference between histogram and frequency
polygon is that in histogram, it is assumed that all scores in a given
class interval are spread uniformly over that class interval, while in
a frequency polygon, we assume tha t all scores in a given interval
are concentrated at the midpoint of that class interval. In other
words, while plotting a frequency polygon, the midpoint of an
interval is always taken to represent the entire interval.
To plot frequency polygon, we fir st need to convert raw data
into grouped frequency table as shown above in table no. 1. Then
we need to calculate the midpoint for each class interval and put
them on x axis. Then on y axis, we need to plot the frequency
corresponding to each class interva l and then to join all these
points by straight line, e.g.,
munotes.in

Page 147

147Table No. 4
Class Interval Midpoints Frequency
129.5 -134.5 132 1
124.5 –129.5 127 1
119.5 -124.5 122 7
114.5 -119.5 117 13
109.5 –114.5 112 18
104.5 -109.5 107 8
99.5 -104.5 102 2
Midpoints are found by adding the upper and lower
boundaries and dividing by 2. For example, 99.5 + 104.5/ 2 =
102,104.5+109.5/ 2 = 107 ,and so on.
Fig.2 Polygon
Some statistician, however, prefer to close both the ends of
the polygon b ye x t e n d i n gt h e mt ot h eb a s el i n e as shown in above
figure .To do this, two hypothetical classes (one on each end) are
added to the frequency table, each with a frequency ofzero.
The polygon is closed at the base by extending it on both its
sides (ends) to the midpoints of two hypothetical classes, at the
extremes of the distribution, with zero frequencies. See Fig.2
On comparing the Histogram and a frequency polygon, you
will notice that, in frequency polygons the points replace the
bars(rectangles). Also, when several distributions are to be
compared on the same graph paper, frequency polygons are better
than Histograms.
munotes.in

Page 148

148Comparison of Histogram and Polygon:
Though no one type of graph is good for all purposes, each
one has its own advantages and di sadvantages.
1.Histogram is easier and best pictorial presentation if only one
distribution is to be shown. If two or more distributions are to be
compared, then polygon is better. For example, if we want to
show graphically the performance of a particular class on one
particular subject such as psychology, we can use histogram
and we will be able to say how many marks majority of the
students have got on that exam. On the other hand, if we want
to graphically present performance of the same students on
numb er of subjects such as English, Psychology, Political
Science, etc. then using polygon will be better for easier
comprehension of the results.
2.Frequency polygons are good for showing the shape of a
distribution. However, a frequency polygon is less precis et h a n
a histogram because it assumes all the scores within a class
interval are at the midpoint which is not anaccurate
represent ation.
8.4MEASURES OF CENTRAL TENDENCY
Though frequency distribution tells us how scores are
distributed in a given data but this does not give us a single score
that is “typical” of that data. Measures of Central Tendency are
those numbers that best represent the most typical scores of a
frequency distribution. These m easures of Central Tendency are
used to represent the en tire distribution of scores which are usually
found near the center of the data when arranged in order of size.
Different measures of central tendency are more or less average
values that represent a group value. Such a value is of great
significance becau se it depicts the characteristic of the whole
group.
The most common measures of C entral Tendency are
Mean, Median and Mode. The various measures of central
tendency have two important uses in psychology.
They are an average which represent all of the scores made by
a group and as such gives a concise description of the
performance of the group as a whole.
It enables us to compare two or more groups in terms of typical
performance. This comparison can be within one group or
between groups of data.
Now let us see how to compute mean, median and mode.munotes.in

Page 149

1498.4.1Mean:
Mean is also called as arithmetic mean or average. It is the
most commonly used measure of central tendency. It is simply the
sum of the numbers divided by the number of numbers. For example,
a)The mean of 7, 12, 24, 20, 19 is (7 + 12 + 24 + 20 + 19) / 5 =
16.4.
b)The mean of the numbers: 1+2+3+6+8=20/5=4.
The formula for mean is
In this formula, each letter and symbol has a specific meaning:
X=It is the symbol of mean.
∑ = It is sigma, the Greek letter for S, and it stands for “sum”, i.e.,
total.
X = It represents the scores in the distribution, so the numerator of
the formula says “sum upall the scores”.
N = N is the total number of scores in a distribution.
So, according to th ef o r m u l a ,t h em e a ni se q u a lt ot h es u m
of all the scores divided by the total number of scores, as shown in
above example.
This formula is useful when the data is not too big and is not
grouped in frequency distribution. But if the data is too large a nd
needs to be grouped then we need another method of computing
the mean.
Although the mean is usually the most representative
measure of central tendency because each score in a distribution is
included in the computation but mean is susceptible to the effects
of extreme scores in a distribution. It means, any unusually high or
low score will pull the mean in its direction and you will not get
correct representation of the distribution.
8.4.2Median:
Median is that value of a variable which divides a series in
two equal parts in such a manner that the number of items below it
is equal to the number of items above it. The median is a positional
average referring to the place of a value in a series. Median is
influenced by the position of items in a se ries and not by the size of
the items like the mean.munotes.in

Page 150

150Median is used under following conditions:
(i)Median is used when the exact midpoint of the distribution is
wanted.
(ii)The median is useful for distribution containing open ended
intervals, since these int ervals do not enter its computation.
(iii)The Median, is almost useful when the distribution has extreme
scores i.e.,
Median is most useful when a given distribution is skewed.
Computation of the Median:
When there is an odd number of scores in an ungrou ped
data, the median is simply the middle number. For example, the
median of 2, 4, 7 is 4. Similarly, the median of 3, 5, 6, 9, 15 is 6.
When there is an even number of numbers, the median is
theaverage of the two middle numbers.
Thus, the median of t he numbers 2,4,7,12 is 4+7 divided by2=5.5.
Similarly, the median of 2, 7, 15, 20 is (7+15)/2 = 11.
8.4.3Mode:
Mode is defined as the most frequently occurring value in a
given data. There are many situations in which arithmetic mean and
median fa il to reveal the true characteristic of data. For example,
when we take the common habitat, attitude, behaviour, etc., we
have in mind mode and not the mean or median. The mean does
not always provide an accurate reflection of the data due to the
presence of extreme items. Median may also prove to be quite
unrepresentative of the data owing to an uneven distribution of the
series. Both these shortcomings can be overcome by the use of the
mode which refers to the value which occurs most frequency in a
distri bution. Mode is used under following conditions:
We use mode with a quick and approximate measure of central
tendency is wanted.
We use mode when information regarding the most typical case,
such as style of dress or shoes is all that is wanted.
Mode is e mployed when the most typical value of a distribution
is desired.
It is the most meaningful measure of central tendency in case of
highly skewed or non -normal distribution as it provides the best
indication of the point of maximum concentration.munotes.in

Page 151

151Example :
a) For individuals having the following ages —18, 18, 19, 20,
20,20, 21, and 23, the mode is 20.
b)Problem: Find the mode from the following data: 7, 13, 18,24, 9,
3, 18
Solution: Ordering the scores from least to greatest, we get: 3,7, 9,
13, 18, 1 8, 24
Answer: The score which occurs most often is 18, Mode = 18
c) Determine the mode of the following scores: 8, 11, 9, 14, 9,15,
18, 6, 9, 15. The mode of the above data is 9 as it is the most
frequently occurring value.
8.5 MEASURES OF VARIABILITY
Measures of variability are also called as the measures of
dispersion or averages of the second order. Average is not always
a good measure of a given distribution. Two or more groups may
have the same average but different variabilities. Too much of
dispersion or spread of the data is not good. Hence, measures of
central tendency should always be accompanied by measures of
variability.
We can define measures of variability as statistics that
describe the amount of difference and how scores are spread out in
a data set. It is a measurement of the degree of differences within a
distribution .
There are many measures of variability. In this sec tion, we
would discuss the two measures of variability which include the
Range ,S t a n d a r dD e v i a t i o n .T h e Z-scoresand normal curve we
shall discus in next section .
These various measures of variability are used for four basic
purposes:
To determine the reliability of an averages;
To serve as a basis for the control of the variability;
To compare two or more serie sw i t hr e g a r dt ot h e i rv a r i a b i l i t y ;
To facilitate the use of other statistical measures that depends
on the variability;
8.5.1 Range:
The Range is one of the crudest, simple and straight -forward
measures of variability which can be defined as the differ encemunotes.in

Page 152

152between the value of the smallest item and the value of the largest
item included in the distribution. In other words, range is the
difference between the highest and the lowest scores in a
distribution. (See the first step in frequency distribution i nt a b l e
no. 1)
Range is not suitable for precise studies.
It is only a rough measure of dispersion. It is useful to compare
groups roughly, when the measures are small. It can’t be used
to compare large groups.
It takes into account the ext reme measures only. Itis generally
used when we need to know the highest and the lowest scores
so as to know the total variation.
It is not a reliable measure of variability.
It can’t be used when there are many gaps in the distribution.
It can be use d when the data are too scant or too scattered to
justify the computation of a precise measure of variability or
when we just want to know the extreme scores of the total
spread.
8.5.2 Standard Deviation:
The standard deviation indicates the “average d eviation”
from the mean, the consistency in the scores, and how far scores
are spread out, around the mean of the distribution. In other words,
it can be defined as the square root of the sum of the squared
deviations from the mean of scores and divided by the number of
scores, in a distribution.
It is one of the most reliable measures of variability.
It is always positive.
It is based on all the observations/scores of the data.
It is a basic building block for analyzing our data.
It provides insights i nto identifying outliers.
It is important in inference.
It is less affected by the fluctuations of sampling than most of
other measures of dispersion.
Let us take an example to see what are the steps needed to
compute standard deviation .munotes.in

Page 153

153Formula for standard deviation is :
SD =
Where
SD = the standard deviation of a sample
∑ = means sum of
X = each score in the data set
X = mean of all scores in the data set
N = number of scores in the data set

Page 154

1541.Arrange the data in ascending order.
2.Add up all the scores in first column (you get sum = 1860).
3.To get the mean, divide the sum of all the scores in first column
with the number of sco res in that column. (1860/15 = 124).
4.Put the mean of the data against each score in second column.
5.In third column, for each score (X), we find the difference
between the X and X. When the mean is subtracted from a
score a score, the result is a deviatio n from the mean. Scores
that are above the mean would have positive deviations and the
scores that are below the mean would have negative deviations.
If the deviations from the mean are added together, the sum will
be 0 because the negative and positive de viations will cancel
each other out.
6.In mathematics, if a negative number is squared, it becomes
positive. So, to get rid of the negative deviations, we will square
off each deviation and put it fourth column. Then we calculate
the sum of these squared d eviations.
7.To get standard deviation, we take the sum of squared
deviations and divide by the total number of cases, and take the
square root.
Standard Deviations a measure of absolute distribution, the
greater the amount of dispersion, the greater th e standard
deviation. standard deviation is generally used under following
conditions:
When further computations that depend on SD are needed.
When we have to compare individuals score on two or more
tests.
When interpretations related to the normal prob ability curve are
desired.
One of the greatest limitations of standard deviation is that it
issensitive to extreme values .
8.6Z–SCORES AND NORMAL CURVE
8.6.1 Z –Scores
Z-scores are one type of standard scores which represents
the differences b etween individual scores and the mean score
expressed in units of standard deviations. Z-scores are a
conversion or transformation of individual scores into a standard
form, where the transformation is based on knowledge about the
population’s mean and sta ndard deviation.
Z–Score can be defined as a statistical measure which
indicates how far away from the mean a particular score is in terms
of the number of standard deviations which exists between the
mean and that score.munotes.in

Page 155

155A positive Z -score means tha t the score is above the mean,
while a negative Z -score means that the score is below the mean.
The larger the z -score, the farther away from the mean the score is.
There are two major uses of Z -score:
It tells the exact location of a score in a distrib ution: For
example, Vijay is09 yrs. old and weighs 40 Kilograms. How
does his weight compare to other children of his age groups?
Z-score allows us to compare twoscores coming from different
distributions. Geeta scored 72 on her Psychology test and 61 on
her biology test, on which test did she perform better? It would
not automatically mean that she did better on Psychology test.
You cannot simply compare two marks from the two classes
because each class is composed of a different population. If
most of t he students from Psychology class get scores in 90s,
then Geeta might be just performing in below average range
and if in biology most of the students have got marks in 50s
then Geeta’s performance comes in above average range. So
the only way to find out would be to convert her scores in the
two subjects into Z -scores.
Z-scores take data of any form and put them into a standard
scale. High score in a distribution always has a positive z -score
and a low score in a distribution always has a negative z scor e.
The formula for computing Z -score is:
z=X–X
SD
X = Raw score
X=M e a n
SD = Standard Deviation
Let us take an example from table no. 4
z=1 4 9 -124/17.10 =1 . 4 6
z= 115 -124/17.10 = -.53
A z score of +1.46 indicates tha t a person scoring 149 marks
falls about one and a half standard deviation above the mean. On
the other hand, a person scoring 115 marks falls below the mean
and has negative z score. A score of 115 is a little more than one -
half a standard deviation belo wt h em e a n .
8.6.2Standard Normal Curve:
It is also called standard normal distribution. Normal Curve is
also called as the Normal Probability Curve, the Gaussian Curve
(after a great German mathematician who investigated its
properties and wrote the e quation for it).munotes.in

Page 156

156Fig.3
It is also called as the Bell -Shaped Curve or Mesokurtic
Curve (Meso means middle or medium). Normal Curve is a special
frequency polygon in which the scores are symmetrically distributed
around the mean.
Inthis curve the mean, median and mode are located
exactly in the middle of the curve with scores decreasing as the
curve extends from the mean. If a line is drawn down its center, one
side of the curve is a mirror image of the other side.
Features of Nor mal Curve:
1.The normal curve is symmetrical about the mean. The number
of cases below the mean in a normal distribution is equal to
number of cases above the mean.
2.The height of the curve is maximum at its mean. Thus, mean,
median, and mode are equal in no rmal probability curve.
3.There is one maximum point of the normal curve which occurs
at the mean. The height of the curve declines as we go in either
direction from the mean. This dropping off is slow at first, then
rapid, and then slow again. This pattern is the reason the
normal curve is often described as “bell shaped”. Theoretically,
the curve never touches the base line. Its tail approaches but
never reach the base line. Hence, the range is unlimited.
munotes.in

Page 157

1574.The point of inflection i.e., the points where the curvature
changes in direction are each plus or/and minus one standard
deviation from the mean ordinate.
5.If a variable is normally distributed, that is, if it has the standard
bell-shaped pattern, a person’s z -score can tell us exactly where
that person s tands relative to everyone else in the distribution.
6.The total interval from plus one standard deviation to minus one
standard deviation contains 68.26% of the cases. Similarly,
99.44% of the total area will be included between the mean
ordinate and an o rdinate 2 standard deviation from the mean.
Similarly, 99.74% of the total area will be included between the
mean ordinate and a point 3 standard deviation away from the
mean.
8.6.3Other Distribution Types
Besides the normal distribution, there are many different
types of distributions that we may get from a given data. Two such
distributions are Skewed Distributions (also called as Skewness)
and Bimodal Distributions:
Skewed Distribution:
It can be defined as a frequency distribution in which most of
the scores fall to one side of the distribution or the other side. The
word skewed means lacking symmetry or distorted.
Skewness shows the direction of symmetry. A distribution is
said to be skewed when the mean and the median fall at different
points in the distribution and the balance or center of gravity is
shifted to one side or the other. In normal distribution, the mean
equals the median and the skewness is of course, zero, themore
nearly the distribution approaches the normal form, the closer
together are the mean and the median and the less the skewness.
Types of Skewed Distributions: There are two types of Skewed
Distributions:
Negatively Skewed
The mass of distributions is concentrated on the right end of
the figure and are spread out more gr adually towards the left. The
left tail is the longest.
Positively Skewed
The mass of distribution is concentrated on the left of the
figure and are spread out more gradually towards the right. The
right tail is the longest. See Fig.4munotes.in

Page 158

158Fig.4
All thr ee types of distribution will look like Fig. 5
Fig.5
Bimodal Distributions:
Some frequency polygons show two high points rather than
just one, such a distribution is called as bimodal distribution. A
bimodal distribution is a frequency distribution in which there are
two high points rather than one. In a bimodal distribution, there are
two peaks in occurrences, so you should see two humps or spikes.
For example, a bimodal distribution would look like figure 6
Fig.6

1598.7THE CORRELATION COEFFICIE NT
Correlation refers to the relationship between two variables.
It is a method of summarizing the relationship between two sets of
data. Correlation is expressed in terms of coefficient of correlation
or Correlation Coefficient. It is denoted as “r”.
Correlation requires two scores from the SAME individuals.
These scores are normally identified as X and Y. The pairs of
scores can be listed in a table or presented in a scatter plot. Usually
the two variables are observed, not manipulated.
A correlati on coefficient is a number that represents the
strength and direction of a relationship existing between two
variables that tells us to what degree one variable varies with the
variations in the other.
Coefficient of correlation is a single number that varies from
+1.00 to 0.00 to -1.00. The number tells us a bout the magnitude or
degree of relationship whereas signs, plus or minus, tel ls us about
the direction of relationship. A number close to 1 (whether positive
or negative) indicates a strong relation ship, while a number close to
0 indicates a weak relationship. Thus +1.00 denotes perfect
positive correlation, whereas -1.00 denotes perfect negative
correlation. In psychology and other social sciences, it is very
difficult or rather impossible to get pe rfect correlation. Such perfect
correlation sare usually obtained in physical sciences.
A correlation coefficient close to zero indicates a weak linear
relationship between two variables.
A correlation coefficient of zero would indicate that there is no
correlation, or relationship, between two variables. For example,
the correlation coefficient between shoe size and number of
books read.
A positive correlation coefficient occurs when the values of both
variables increase together. That is, an increase in one variable
tends to be associated with an increase in the other variable .
For example, relationship between studying hard and high
grades in school. Those who study more, get higher grades in
school. Take another example of height and weight. Taller a
person is, heavier he will be.
A negative correlation coefficient occurs when the increase of
one variable corresponds with the decrease of another variable.
That is an increase in one variable tends to be associated with a
decrease in the other variable in the same proportion. For
example, the more you study, less the chances of failure. Take
another example, the relationship between the height above themunotes.in

Page 160

160sea level and temperature. As the height above the sea level
increases, the temperature drops and it get sc o l d e r .
So, w hen increase in one variable lead to simultaneous
increase in another variable or vice versa, it is called as positive
correlation. On the other hand, when increase in one variable leads
to decreases in other variable or vice versa it is called as negative
correlation. When increase or decrease in one variable does not
affect the other variable in any manner, then it is called as zero
correlation.
Correlation coefficient is computed by using following formula:
∑ ZxZy
Correlation coefficient = -----------------
N
Steps in Computation of Correlation Coefficient:
1.As mentioned above, correlation is computed between two
variables and for computation purpose we call them X and Y. To
compute a correlation coefficient, the data from both variables
can be converted to z scores. So, each individual will have two z
scores –one for X variable and one for Y variable.
2.Each person’s two z scores are multiplied together.
3.All these cross p roducts are added up
4.The sum of all cross products is divided by the number of
individuals.
Thus, correlation coefficient is the mean of the sum of the
products of the z scores for the two variables. In terms of z scores -
Inpositive correlation, hig h z scores on one variable tend to be
multiplied by high z scores on the other variable and the low z
scores on one variable tend to be multiplied by low z score on
the other variable. However, the sum of cross products is
always positive in both cases, b ecause when two negative
numbers are multiplied, they result in a positive number.
In negative correlation, high z scores (which are positive) on
one variable tend to be multiplied by low z scores (which are
negative) on the other variable, and vice vers a. This results in
negative cross products. So, when the sum of these negative
cross products is divided by N, the result is a negative
correlation coefficient.
The following figure depicts the graphic representation of
different types of correlation. Plotting two variables together creates
a scatter diagram or scatter plot.munotes.in

Page 161

161As you can see in fig. 7 and Fig. 8, positive relationship
generally forms a line running from lower left to upper right. A
perfect negative relationship generally forms a line ru nning from
upper left -hand corner of the graph to lower right -hand corner of the
graph.
The minimum coefficient is .00, which indicates there is no
consistent relationship between the two variables. From a z -score
point of view, when two variables are n ot related, the cross -
products are mixed, that is, some are positive and some are
negative. In other words, sometimes high z scores on one variable
go with high z scores on the other and low z scores on one variable
go with low z scores on the other. When the cross products for the
two variables are summed, the positive and negative numbers
cancel each other out, resulting in a 0 correlation.
From this minimum value, the coefficients increase in both
directions until -1.00 is reached on one side and +1.0 0 is reached
on the other side. Both -1.00 and +1.00 indicate perfect and close
relationship between the two variables. The sign of plus or minus
indicates the direction of the relationship while the number indicates
the magnitude of the relationship.

Uses of Correlation Method:
1.Relationship: Correlation allows the researcher to investigate
naturally occurring variables that maybe unethical or impractical to
test experimentally. For example, it would be unethic al to conduct
an experiment on whether smoking causes lung cancer. Correlation
allows the researcher to clearly and easily see if there is a
relationship between variables. This can then be displayed in a
graphical form.
2.Prediction: The coefficient is u seful in predicting the
performance on the second variable by knowing the score on the
first variable.
Causality: However, correlation does not necessarily mean
causation. The fact that two variables are highly correlated does not
necessarily mean that o ne variable directly causes the other. For
example, there might be a strong correlation between ice -cream
sales and the sale of sunglasses. Can we say buying ice -cream
causes people to buy sunglasses also? NO, there can be other
reasons for positive correl ation between the sale of ice -cream and
sunglasses and that is hot weather.
Experimental method is the only method that can give strong
scientific evidence of cause -and-effect relationship between two or
more variables.
8.8INFERENTIAL STATISTICS
Inferential statistics is a branch of statistics which helps us to
draw inferences about the population on the basis of sample. It
enables us to make confident decisions in the face of uncertainty.
Inferential statistics consists of statistical technique st h a ta l l o w
researchers to determine how likely it is that a study’s outcome is
due to chance and whether the outcome can be legitimately
gene ralized to a larger population.munotes.in

Page 163

163There are many different kinds of inferential statistical
methods. The method t hat is used depends on the design of the
experiment, such as number of independent and dependent
variables or the number of experimental groups. It allows
researchers to determine the difference between results of a study
that are meaningful and those that are merely due to chance
variations.
Statistical Significance:
Inferential statistics allows researchers to determine how
much confidence they should have in the results of a particular
experiment. If inferential statistics indicates that the odds of a
particular finding occurring are considerably greater than mere
chance, we can conclude that our results are statistically significant.
Statistically significant results indicate that we can conclude with a
high degree of confidence that the manipulation of the independent
variable, rather than simply chance, is the reason for the results. In
other words, statistical significance is a way to test differences to
see how likely those differences are to be real and not just caused
by the random variations in behavior that exist in everything
animals and people do.
Inferential statistics uses wide variety of statistical tests,
some of which include the T test, the F test, Chi Square, etc. For
example ,t-tests are used to compare the means of two groups.
Analysis of variance(ANOVA) is used to compare the means of
more than two groups.
Type I & Type II Error:
In psychology, we can’t be fully sure that our
intervention/manipulation only was responsible for the results that
we have got. We always have to deal with probabilities and not
certainties. Since researchers are dealing with probabilities, there is
always a small but real possibility of erroneously concluding that
study results are significant. Here the term error does not mean
mistakes or inaccuracies which may be committed in making
observations, counting and calculations, etc. It refers to the
difference between the true value of a parameter and its estimate
provided by an appropriate sample statistic. There are two types of
errors that may occur –Type I error and Type II error.
A Type I error occurs when the results show that a difference
exists but in reality, there is no difference. So, the results of one
study should never be trusted completely. It is asserting something
that is absent, a false hit.To have greater confidence in a particular
effect or result, the study should be repeated or replicated. If the
same results are obtained in different studies, then we can be more
certain that our results about a particular effect are correct.munotes.in

Page 164

164AT y pe II error occurs when a researcher fails to find a
significant effect, yet that significant effect really exists. It is failing
to assert what is present, a miss. A Type II error occurs when a
study does not have enough power. In other words, the study i sn o t
strong enough to find the effect the researcher is looking for. Higher
power may be achieved by improving the research design and
measuring instruments or by increasing the number of participants
being studied.
Population vs. Sample:
Ap o p u l a t i o n is a complete set of something -people,
nonhuman animals, objects or events. For example, if I want to
conduct a study on the study habits of students in the age group of
18 to 25, residing in Mumbai, and irrespective of stream they
belong to. They may be students of Arts, Science, Commerce,
Medical or Engineering stream or any other stream. Logistically, it
won’t be possible for me to cover each and every student in that
age group and residing in Mumbai. So to conduct such a study, the
best way is to take a small portion of this population, to serve as
subjects in this study.
A subset of population is known as Sample. The researchers
conduct study on the carefully chosen sample . They analyze the
results of this sample, using inferential statistics to mak e guesses
about what they would have found had they studied the entire
population. Inferential statistics enables researchers to take the
findings they get from a sample and apply them to a population.
Population here does not mean the population of a coun try.
Population is also defined as a specific segment of the society as
stated in above example.
8.9SUMMARY
This unit began by discussing as to why psychologists use
statistics, followed by the definition of descriptive statistics and its
types. In descriptive statistics, we discussed the concept of
frequency distribution, histogram and frequency polygon. The
concept of normal curve as well as its characteristics was also
discussed. We have also discussed the skewed distribution and its
types as wel l as bimodal distributions. Measures of central
tendency such as mean median and mode were discussed and its
computation for ungrouped data was demonstrated. Measures of
variability such as range and standard deviation were also
discussed. The concept of Z -score was explained. The concept of
inferential statistics as well as correlation coefficient was also
discussed. Inferential statistics included types of tests used, types
of errors and difference between population and sample.munotes.in
