NATURE AND FORMATION OF GROUPS
What is a Group?
The preceding introduction illustrates the
importance of groups in our lives. One
question that comes to mind is: “How are
groups (e.g., your family, class, and the
group with which you play) different from
other collections of people?” For example,
people who have assembled to watch a
cricket match or your school function are
at one place, but are not interdependent
on each other. They do not have defined
roles, status and expectations from each
other. In the case of your family, class,
and the group with which you play, you
will realise that there is mutual
interdependence, each member has roles,
there are status differentials, and there
are expectations from each other. Thus,
your family, class and playgroup are
examples of groups and are different from
other collections of people.
A group may be defined as an
organised system of two or more
individuals, who are interacting and
interdependent, who have common motives,
have a set of role relationships among its
members, and have norms that regulate
the behaviour of its members.
  Groups have the following salient
characteristics :
• A social unit consisting of two or more
individuals who perceive themselves
as belonging to the group. This
characteristic of the group helps in
distinguishing one group from the
other and gives the group its unique
identity.
• A collection of individuals who have
common motives and goals. Groups
function either working towards a
given goal, or away from certain
threats facing the group.
• A collection of individuals who are
interdependent, i.e. what one is doing
may have consequences for others.
Think about your day-to-day life and the various social interactions you have.
In the morning, before going to school, you interact with your family members;
in school, you discuss topics and issues with your teachers and classmates;
and after school you phone up, visit or play with your friends.  In each of
these instances, you are part of a group which not only provides you the
needed support and comfort but also facilitates your growth and development
as an individual. Have you ever been away to a place where you were
without your family, school, and friends?  How did you feel?  Did you feel
there was something vital missing in your life?
    Our lives are influenced by the nature of group membership we have.  It is,
therefore, important to be part of groups which would influence us positively
and help us in becoming good citizens. In this chapter, we shall try to
understand what groups are and how they influence our behaviour. At this
point, it is also important to acknowledge that not only do others influence us,
but we, as individuals, are also capable of changing others and the society.

Teams are special kinds of groups.
Members of teams often have comple-

common goal or purpose. Members are
mutually accountable for their activities.
In teams, there is a positive synergy
attained through the coordinated efforts
of the members. The main differences
between groups and teams are:
• In groups, performance is dependent
on contributions of individual
members.  In teams, both individual
contributions and teamwork matter.
• In groups, the leader or whoever is
heading the group holds responsibility
for the work. However in teams,
although there is a leader, members
hold themselves responsible.

An audience is also a collection of
people who have assembled for a special
purpose, may be to watch a cricket match
or a movie. Audiences are generally passive
but sometimes they go into a frenzy and
become mobs. In mobs, there is a definite
sense of purpose. There is polarisation in
attention, and actions of persons are in a
common direction. Mob behaviour is
characterised by homogeneity of thought
and behaviour as well as impulsivity.
Why Do People Join Groups?
All of you are members of your family,
class and groups with which you interact
or play. Similarly, other people are also
members of a number of groups at any
given time. Different groups satisfy
different needs, and therefore, we are
simultaneously members of different
groups. This sometimes creates pressures
for us because there may be competing
demands and expectations. Most often we
are able to handle these competing
demands and expectations. People join
groups because these groups satisfy a
range of needs. In general, people join
groups for the following reasons :
• Security : When we are alone, we feel
insecure. Groups reduce this
insecurity. Being with people gives a
sense of comfort, and protection. As a
result, people feel stronger, and are less
vulnerable to threats.
• Status : When we are members of a
group that is perceived to be important
by others, we feel recognised and
experience a sense of power. Suppose
your school wins in an inter-
institutional debate competition, you
feel proud and think that you are better
than others.
• Self-esteem : Groups provide feelings of
self-worth and establish a positive social
identity. Being a member of prestigious
groups enhances one’s self-concept.
• Satisfaction of one’s psychological
and social needs : Groups satisfy
one’s social and psychological needs
such as sense of belongingness, giving
and receiving attention, love, and
power through a group.
• Goal achievement : Groups help in
achieving such goals which cannot be
attained individually. There is power in
the majority.
• Provide knowledge and information :
Group membership provides knowledge
and information and thus broadens our
view. As individuals, we may not have
all the required information. Groups
supplement this information and
knowledge.
Group Formation
In this section, we will see how groups are
formed. Basic to group formation is some
contact and some form of interaction
between people. This interaction is
facilitated by the following conditions:
• Proximity : Just think about your
group of friends. Would you have been
friends if you were not living in the
same colony, or going to the same
school, or may be playing in the same
playground? Probably your answer
would be ‘No’. Repeated interactions
with the same set of individuals give us
a chance to know them, and their
interests and attitudes. Common
interests, attitudes, and background
are important determinants of your
liking for your group members.
•  Similarity : Being exposed to someone
over a period of time makes us assess
our similarities and paves the way for
formation of groups. Why do we like
people who are similar? Psychologists
have given several explanations for this.
One explanation is that people prefer
consistency and like relationships that
are consistent. When two people are

importance of groups in our lives. One
question that comes to mind is: “How are
groups (e.g., your family, class, and the
group with which you play) different from

people who have assembled to watch a

will realise that there is mutual
interdependence, each member has roles,
there are status differentials, and there
are expectations from each other. Thus,
your family, class and playgroup are
examples of groups and are different from
other collections of people.
A group may be defined as an
organised system of two or more
individuals, who are interacting and
interdependent, who have common motives,
have a set of role relationships among its
members, and have norms that regulate
the behaviour of its members.
  Groups have the following salient
characteristics :
• A social unit consisting of two or more
individuals who perceive themselves
as belonging to the group. This
characteristic of the group helps in
distinguishing one group from the
other and gives the group its unique
identity.
• A collection of individuals who have
common motives and goals. Groups
function either working towards a
given goal, or away from certain
threats facing the group.
• A collection of individuals who are
interdependent, i.e. what one is doing
may have consequences for others.
Think about your day-to-day life and the various social interactions you have.
In the morning, before going to school, you interact with your family members;

and after school you phone up, visit or play with your friends.  In each of

An audience is also a collection of
people who have assembled for a special
purpose, may be to watch a cricket match
or a movie. Audiences are generally passive
but sometimes they go into a frenzy and
become mobs. In mobs, there is a definite
sense of purpose. There is polarisation in
attention, and actions of persons are in a
common direction. Mob behaviour is
characterised by homogeneity of thought
and behaviour as well as impulsivity.
Why Do People Join Groups?
All of you are members of your family,
class and groups with which you interact
or play. Similarly, other people are also
members of a number of groups at any
given time. Different groups satisfy
different needs, and therefore, we are
simultaneously members of different
groups. This sometimes creates pressures
for us because there may be competing
demands and expectations. Most often we
are able to handle these competing
demands and expectations. People join
groups because these groups satisfy a
range of needs. In general, people join
groups for the following reasons :
• Security : When we are alone, we feel
insecure. Groups reduce this
insecurity. Being with people gives a
sense of comfort, and protection. As a
result, people feel stronger, and are less
vulnerable to threats.
• Status : When we are members of a
group that is perceived to be important
by others, we feel recognised and
experience a sense of power. Suppose
your school wins in an inter-
institutional debate competition, you
feel proud and think that you are better
than others.
• Self-esteem : Groups provide feelings of
self-worth and establish a positive social
identity. Being a member of prestigious
groups enhances one’s self-concept.
• Satisfaction of one’s psychological
and social needs : Groups satisfy
one’s social and psychological needs
such as sense of belongingness, giving
and receiving attention, love, and
power through a group.
• Goal achievement : Groups help in
achieving such goals which cannot be
attained individually. There is power in
the majority.
• Provide knowledge and information :
Group membership provides knowledge
and information and thus broadens our
view. As individuals, we may not have
all the required information. Groups
supplement this information and
knowledge.
Group Formation
In this section, we will see how groups are
formed. Basic to group formation is some
contact and some form of interaction
between people. This interaction is
facilitated by the following conditions:
• Proximity : Just think about your
group of friends. Would you have been
friends if you were not living in the
same colony, or going to the same
school, or may be playing in the same
playground? Probably your answer
would be ‘No’. Repeated interactions
with the same set of individuals give us
a chance to know them, and their
interests and attitudes. Common
interests, attitudes, and background
are important determinants of your
liking for your group members.
•  Similarity : Being exposed to someone
over a period of time makes us assess
our similarities and paves the way for
formation of groups. Why do we like
people who are similar? Psychologists
have given several explanations for this.
One explanation is that people prefer
consistency and like relationships that
are consistent. When two people are
2024-25
Psychology
124
similar, there is consistency and they
start liking each other. For example,
you like playing football and another
person in your class also loves playing
football; there is a matching of your
interests. There are higher chances that
you may become friends. Another
explanation given by psychologists is
that when we meet similar people, they
reinforce and validate our opinions and
values, we feel we are right and thus we
start liking them. Suppose you are of
the opinion that too much watching of
television is not good, because it shows
too much violence. You meet someone
who also has similar views. This
validates your opinion, and you start
liking the person who was instrumental
in validating your opinion.
• Common motives and goals : When
people have common motives or goals,
they get together and form a group
which may facilitate their goal
attainment. Suppose you want to teach
children in a slum area who are unable
to go to school. You cannot do this
alone because you have your own
studies and homework. You, therefore,
form a group of like-minded friends and
start teaching these children. So you
have been able to achieve what you
could not have done alone.
Stages of Group Formation
Remember that, like everything else in life,
groups develop. You do not become a
group member the moment you come
together. Groups usually go through
different stages of formation, conflict,
stabilisation, performance, and dismissal.
Tuckman suggested that groups pass
through five developmental sequences.
These are: forming, storming, norming,
performing and adjourning.
• When group members first meet, there
is a great deal of uncertainty about the
group, the goal, and how it is to be
achieved. People try to know each other
and assess whether they will fit in.
There is excitement as well as
apprehensions. This stage is called the
forming stage.
• Often, after this stage, there is a stage
of intragroup conflict which is referred
to as storming. In this stage, there is
conflict among members about how the
target of the group is to be achieved,
who is to control the group and its
resources, and who is to perform what
task. When this stage is complete, some
sort of hierarchy of leadership in the
group develops and a clear vision as to
how to achieve the group goal.
• The storming stage is followed by
another stage known as norming.
Group members by this time develop
norms related to group behaviour. This
leads to development of a positive group
identity.
• The fourth stage is performing. By this
time, the structure of the group has
evolved and is accepted by group
members. The group moves towards
achieving the group goal. For some
groups, this may be the last stage of
group development.
• However, for some groups, for example,
in the case of an organising committee
Activity
7.1
Identifying Stages of Group
Formation
Select 10 members from your class
randomly and form a committee to
plan an open house. See how they go
ahead. Give them full autonomy to do
all the planning. Other members of the
class observe them as they function.
Do you see any of these stages
emerging? Which were those? What
was the order of stages? Which stages
were skipped?
Discuss in the class.
