Title: Group Processes
1Chapter 8
2Why Join a Group?
- The complexities and ambitions of human life
require that we work in groups - Humans have an innate need to belong to groups
- Social brain hypothesis
- May not only protect against physical threat, but
also help gain personal and social identity
3What is a Group?
- A set of individuals who have at least one of the
following characteristics - Direct interactions with each other over a period
of time - Joint membership in a social category based on
sex, race, or other attributes - A shared common fate, identity, or set of goals
4Group Roles
- Peoples roles in a group can be formal or
informal. - Two fundamental types of roles
- An instrumental role to help the group achieve
its tasks - An expressive role to provide emotional support
and maintain morale - Beneficial to match roles to each members
characteristics and skill set
5Group Norms
- Groups establish norms or rules of conduct for
members. - Norms may be either formal or informal.
6Group Cohesiveness
- The forces exerted on a group that push its
members closer together. - Cohesiveness and group performance are causally
related. - But relationship is complex
- Group cohesiveness can be affected in different
ways as a function of cultural differences.
7Social FacilitationWhen Others Arouse Us
- How does the presence of others affect our
behavior? - Tripletts (1897-1898) fishing reel studies
- Later research found conflicting findings.
- Sometimes the presence of others enhanced
performance. - At other times, performance declined.
- What was going on?
- The Zajonc Solution
8Social Facilitation The Zajonc Solution
9Why Does Social Facilitation Occur?
- Zajoncs Mere Presence Theory
- Evaluation Apprehension Theory
- Someone must be in position to evaluate
performance. - Stereotype threat revisited.
10Why Does Social Facilitation Occur? (contd)
- Distraction Conflict Theory
- Attentional conflict between focusing on task and
inspecting the distracting stimulus creates
arousal. - Maintains there is nothing uniquely social about
social facilitation. - Which theory is correct?
11Social Loafing When Others Relax Us
- Ringelmann (1880s) Individual output declines on
pooled tasks. - Social Loafing A group-produced reduction in
individual output on easy tasks in which
contributions are pooled.
12When Is Social Loafing Less Likely to Occur?
- People believe that their own performances can be
identified and thus evaluated, by themselves or
by others. - The task is important or meaningful to those
performing it. - People believe that their own efforts are
necessary for a successful outcome.
13When Is Social Loafing Less Likely to Occur?
(contd)
- The group expects to be punished for poor
performance. - The group is small.
- The group is cohesive.
14Why Does Social Loafing Occur?
- Collective Effort Model Individuals try hard on
a collective task when they think their efforts
will help them achieve outcomes they personally
value.
15Culture and Social Loafing
- Prevalent around the world, but some cultural
differences have been found - Research has found social loafing to be less
prevalent among women than men, and less
prevalent in collectivist cultures than in
individualist cultures
16Deindividuation
- The loss of a persons sense of individuality and
the reduction of normal constraints against
deviant behavior. - A collective phenomenon that only occurs in the
presence of others - What can lead to deindividuation?
17Group PerformanceProblems and Solutions
18Brainstorming
- A technique that attempts to increase the
production of creative ideas by encouraging group
members to speak freely without criticizing their
own or others contributions.
19Brainstorming in Groups
20Group Polarization
- Conflicting findings about the types of decisions
groups make - Sometimes riskier, other times more cautious
- Group Polarization The exaggeration through
group discussion of initial tendencies in the
thinking of group members.
21What Creates Group Polarization?
- Persuasive arguments theory
- Social comparison
- To differentiate from other groups
22Groupthink
- Excessive tendency to seek concurrence among
group members. - Emerges when the need for agreement takes
priority over the motivation to obtain accurate
information and make appropriate decisions.
23Symptoms of Groupthink
- Overestimation of the group
- Closed-mindedness
- Increased pressures toward uniformity
- Mindguards and pressures towards uniformity
- Self-censorship
- Illusion of unanimity
24Preventing Groupthink
- Avoid isolation by consulting widely with
outsiders. - Leaders should reduce conformity pressures.
- Establish a strong norm of critical review.
25Charting the Course of Groupthink
26Escalation Effects
- Occurs when commitment to a failing course of
action is increased to justify previous
investments. - Groups more likely to escalate commitment.
- Also likely to do it in more extreme ways.
27Conflict Cooperation and Competition Within and
Between Groups
28The Prisoners Dilemma
- Is a type of dilemma in which one party must make
either cooperative or competitive moves in
relation to another party. The dilemma is
typically designed so that the competitive move
appears to be in ones self-interest, but if both
sides make this move, they both suffer more than
if they had both cooperated
29Culture and Social Dilemmas
- Evidence of strong cultural differences is mixed
thus far - Collectivistic cultures may cooperate more with
friends or ingroup members, but compete more
aggressively with outgroup members
30Conflict Escalation and Reduction
- Conflicts between groups are caused by many
factors, including competition for scarce
resources, stereotypes and prejudice, and
competing ideologies.
31Reducing Conflict Through GRIT
- Graduated and Reciprocated Initiatives in
Tension-Reduction (GRIT) - A strategy for unilateral, persistent efforts to
establish trust and cooperation between opposing
parties. - GRIT is a reciprocal strategy
- Research on GRIT is encouraging
32Negotiation
- Integrative agreement is a negotiated resolution
where all parties obtain outcomes that are
superior to a 50-50 split.
33Negotiation (contd)
- Key elements in successful negotiating include
- Communicating and trying to understand the point
of view of the other person - Disclosure of information
- Training in conflict-resolution techniques
- Simply taking a break
- Sometimes an arbiter is necessary
34Finding A Common Ground
- Recognition of a superordinate identity.
- Superordinate goals can elicit cooperation by
appealing to peoples self-interest. - These goals can also produce a superordinate
identity.
