Definition
Reasons for joining groups
Types
Characteristics of groups
Group processes

Two or more individuals that communicate
in an interdependent relationship in order
to achieve a common purpose



Security: e.g., joining a trade union
representing employees in one’s occupation
Status: joining a group, because it bestows
the professional status one is seeking
Affiliation: a desire to join a group capable
of fulfilling one’s social needs


Power: a realization that the group is
functional in grabbing power and in joining
forces with others to counteract external
threats
Goal attainment: joining forces with
competent people to achieve work targets





Formal or informal: officially created vs.
spontaneously formed
Primary or secondary: close vs. impersonal
Co-acting: members act independently
Counteracting: competition between
members is pronounced
Reference: people show an eagerness to
identify with the group




Norms: expectations or standards of
behaviour shared by the group
Cohesiveness: extent to which members are
attracted to each other and are motivated to
remain in the group
Communication and interaction
Structural factors: atmosphere, roles,
status, composition, size, leadership, and
group dynamics



Structure and atmosphere: group structure
and organizational features and their
effects on innovation and performance
Roles: sets of expected patterns of
behaviour applicable to a role occupant
Various aspects of roles: e.g., expected,
perceived, enacted






Problems: role ambiguity and role conflict
Status within groups, and problems with
status (incongruency and discrepancy)
Group composition: significance of
homogeneity and heterogeneity
Group size: its significance of size in terms
of effectiveness
Size and social loafing
Leadership: its changing nature within
groups



Psychoanalytical view of group dynamics:
individual’s emotional reaction arising from
identification with the group. Bion’s
unconscious processes (fight/flight,
dependency, pairing)
Reference groups: provide a comparative
reference point
Social comparison: amounts to lateral
influence, where other people’s views are
considered before making the most
appropriate response




Co-action and affiliation: individual’s
behaviour is influenced by being in the
company of others
Social control: influence is exerted
vertically, as opposed to horizontally, as in
social comparison
Decision making: acceptability of decision if
members have the opportunity to
participate in the decision deliberations
Decision making: groupthink and risky shift





We consider how others respond in a
particular situation
As a social comparative agent, group norms
are important
Significance of norms in the bank wiring
room (Hawthorne Experiments)
Importance of group norms in conditions of
uncertainty (Sheriff)
Group influence where uncertainty is absent
(Asch)



Being in the company of others has a
material bearing on the behaviour of the
individual
In the company of others, a state of arousal
develops inviting a behavioural response
We associate with others when overcome by
fear



Types of decision making groups:
interacting, nominal and Delphi groups
Alleged benefits of involvement of
members, and discussion in the decision
making process
Group discussion could be undermined if
the discussion is limited and the group tries
to overpower individuals


Groupthink: tends to push aside a realistic
appraisal of alternative courses of action,
and with its striving for unanimity can have
a disarming effect (Janis)
Risk taking and the risky shift (groups are
prepared to take greater risks than
individuals)




A highly cohesive group may suffer the
symptoms of groupthink, particularly when
the group is isolated from alternative views
or external advice
Illusion of invulnerability: characterized by
excessive optimism
Rationalize away unpopular solutions
Belief that group actions or decisions are
intrinsically right or moral






Negative views of the opposition externally
Pressure on members to conform
Member’s inclination to minimize
importance of self-doubt
Illusion of unanimity, due to selfcensorship and acquiescence
Mindguards: protect the group from
adverse information
Measures to counteract groupthink



Individuals tend to take fewer risks than
groups
Membership of a group influences the
individual to adopt a riskier position; this is
called risky shift
One explanation to account for risky shift is
diffusion of responsibility within the group,
when individuals feel less responsibility for
the consequences of their actions


Cautious shift: tendency of a group to be
more conservative than the individual in
some circumstances
Risky or cautious shifts are known as ‘group
polarization’


Ways groups interact with other groups
within the organization
Difficulties arise when there is an absence
of harmonious relationships
