Week 5: The Psychology of Groups

Overview of Group Psychology

• Understanding people necessitates an examination of the groups to which they belong. Groups significantly influence individual behaviors, choices, and identities.

• Individuals possess personal objectives but are shaped by group dynamics, fulfilling needs for belonging and social identity.

Importance of Groups

• Much of the world’s work is executed by groups rather than individuals, highlighting the significance of group structure.

• Effective teamwork can increase the likelihood of success in project execution and is vital in decision-making contexts.

• Groups may face challenges such as group polarization (the tendency for groups to make more extreme decisions) and groupthink (a phenomenon where the desire for harmony leads to poor decision-making).

Psychological Significance of Groups

The Need to Belong

• The need to belong is a substantial motivator in human behavior. Individuals often prefer inclusion over exclusion, as emphasized by Baumeister and Leary’s (1995) work on the drive for forming and maintaining relationships.

• Surveys indicate that a high percentage of Americans participate in group activities, which correlates positively with happiness and life satisfaction.

Effects of Exclusion

• Rejection from groups can evoke a range of negative emotions, including unhappiness, depression, and confusion. Psychological studies show that social exclusion elicits physical pain sensations, demonstrating its profound psychological impact.

Affiliation in Groups

Social Comparison

• Groups are instrumental for social support and information. Festinger’s (1954) social comparison theory posits that individuals seek affiliation in uncertain situations for reassurance and accurate self-evaluation.

• Downward social comparison, where individuals compare themselves with others who are worse off, is a means of maintaining self-esteem.

Identity and Membership

• An individual's self-concept includes traits and qualities derived from group affiliations. Social identity theory (Tajfel & Turner, 1979) elucidates that people categorize themselves within social groups, impacting self-perception and behaviors.

• Group membership can profoundly influence self-worth and collective self-esteem.

Evolutionary Advantages of Group Living

Biological Perspectives

• The tendency to form groups also has a biological underpinning, enhancing individual fitness. Social integration theory suggests that individuals form groups based on interdependence to fulfill basic needs, supporting survival and well-being.

Motivation and Performance in Groups

Social Facilitation

• The phenomenon of social facilitation shows that individual performance can improve in a group context, a finding backed by Norman Triplett’s experiments with cyclists.

• Zajonc (1965) found that performance improvement is more pronounced on well-practiced tasks rather than unfamiliar ones.

Social Loafing

• Conversely, group performance can suffer due to social loafing, where individuals exert less effort in a group than when they work alone. Latané et al. (1979) found that as group size increases, individual effort tends to decrease, illustrating a common issue in group dynamics.

Enhancing Team Performance

Importance of Teamwork

• Successful teamwork hinges on integrating individual skills towards achieving collective goals. Effective teams require shared mental models and unity among members.

• Cohesive groups often demonstrate higher productivity; however, this can lead to adverse effects if norms prioritize low productivity.

Group Development

Stages of Group Development

• Tuckman’s (1965) model outlines the five stages of group development: forming, storming, norming, performing, and adjourning. This model emphasizes the evolution of group dynamics over time, including establishing conflicts, norms, and cohesion.

• Group socialization involves a gradual process of acceptance and commitment from both members and the group as a whole.

Decision Making in Groups

Benefits of Group Decisions

• Groups can leverage more diverse information and viewpoints than individuals during decision-making processes. This collective discussion can lead to better evaluations of options compared to solitary decisions.

• However, groups are also susceptible to poor outcomes influenced by group dynamics.

Group Polarization

• During discussions, groups frequently polarize toward more extreme judgments rather than moderating opinions, which can result in decision-making extremes.

• The common knowledge effect can result in groups focusing on widely shared information, overshadowing critical but less common insights.

Groupthink

• Janis (1982) defined groupthink as a dysfunctional thinking mode prevalent in cohesive groups, often leading to suboptimal or disastrous decision-making.

• Symptoms of groupthink include overconfidence among group members, flawed perceptions of alternatives, and pressure for conformity leading to suppression of dissenting opinions. Factors such as high cohesion, isolation from dissenting views, biased leadership, and pressure under decisional stress contribute to its occurrence.

Summary of Key Vocabulary

• Collective self-esteem: Feelings of self-worth based on relationships and group memberships.

• Common knowledge effect: A bias toward discussing shared knowledge rather than unique information in group settings.

• Group cohesion: Unity arising from strong interpersonal bonds among group members, often leading to enhanced performance.

• Social facilitation: The improvement in individual performance when in the presence of others.

• Social loafing: The tendency of individuals to exert less effort in a group compared to working alone.

• Teamwork: The coordinated effort of individual skills to attain a shared goal.

• Challenges: Groups may face challenges such as group polarization (the tendency for groups to make more extreme decisions) and groupthink (a phenomenon where the desire for harmony leads to poor decision-making).

• Case Study Recommendation: Implement structured decision-making processes to mitigate these effects. For instance, using techniques such as the Devil’s Advocate approach can stimulate critical thinking and prevent groupthink.

• Case Study Recommendation: Foster inclusive environments in which relationships and group activities are encouraged, leading to improved happiness and life satisfaction.

Effects of Exclusion

Rejection from groups can evoke a range of negative emotions, including unhappiness, depression, and confusion. Psychological studies show that social exclusion elicits physical pain sensations, demonstrating its profound psychological impact.

• Case Study Recommendation: Introduce programs to identify and support individuals facing exclusion to enhance their psychological resilience.
