In-Depth Notes on Group Processes and Social Dynamics

Entitativity

• Definition: Entitativity refers to the degree to which a collection of people feels like a cohesive group.

• Features of a Cohesive Group:

  • Common Bond:

  • Degree of interaction and dependence among members.

  • Examples:

    • Communal Sharing: Members share resources and emphasize group identity.

    • Market Pricing: Members trade resources in a transactional manner.

  • Common Identity:

  • Members share similar characteristics and group identity.

  • Examples of shared identity can include a challenge or threat faced by the group.

Why Join Groups?

• Promoting Survival and Achieving Goals:

  • Group membership enhances survival, indicating a tendency to identify with kinship groups.

  • Groups assist in goal completion.

• Reducing Uncertainty:

  • Uncertainty-Identity Theory: People join groups to combat negative feelings of uncertainty about themselves and others.

  • Groups help enforce cultural worldviews and norms for behavior.

• Bolstering Self-Esteem:

  • Social Identity Theory: Group identities are a core part of self-definition.

  • Importance of identification with successful or high-status groups leading to in-group bias.

• Managing Mortality Concerns:

  • Membership provides a connection to something greater than individual existence.

Social Dilemmas and the Science of Cooperation

• Definition: Social dilemmas occur when individual self-interest conflicts with collective social goals.

• Resource Dilemmas:

  • Common Dilemma: Using scarce resources benefits the individual but harms the group (e.g., environmental issues).

  • Public Goods Dilemma: Shared resources are maintained only through collective contributions.

• Free Riders Problem: Both dilemmas identify the issue where some individuals benefit without contributing, potentially leading to collapse of cooperation.

Cooperation in Groups

• Factors influencing cooperation:

  • Situational Factors: Social norms play a significant role.

  • Personality Traits: Agreeableness is often associated with cooperation.

  • Biological Bases: Hormones like oxytocin may promote cooperative behavior.

Social Facilitation Theory

• Theory Overview: The presence of others increases the likelihood of a person’s dominant response in performance tasks.

  • Zajonc (1965) refined the theory by stating that while the presence of others is expected to enhance performance on simple tasks, it can hinder performance on complex (less practiced) tasks.

Evaluation Apprehension

• Impact of Evaluation:

  • The awareness of being evaluated can trigger distracting thoughts that reduce working memory capacity.

  • Social evaluation leads to impaired performance in various areas (sports, music, etc.).

Social Loafing

• Definition: Tendency to exert less effort when working in a group compared to working alone.

• Reasons for Social Loafing:

  • Low accountability and perceived dispensability in group tasks.

  • Lack of personal interest in uninteresting tasks.

Deindividuation

• Definition: The loss of self-awareness and individuality in groups.

• Conditions for Increased Deindividuation:

  • Overstimulation, high cognitive load, larger group sizes, and lack of individual cues.

• Implications: Can lead to severe societal issues, though bad behavior isn't guaranteed.

Group Decision Making

• Two pitfalls: Group Polarization and Groupthink.

  • Group Polarization: Discussions can push groups toward extreme positions.

  • Groupthink: Desire for harmony results in poor decision-making, where dissent is suppressed, and alternative options are overlooked.

Improving Group Decision-Making

• Strategies:

  • Increase group diversity and reinterpret cohesion to promote individuality.

  • Plan to maintain objectivity in discussions.

Effective Leaders

• Traits of effective leaders include:

  • High extraversion, openness, and conscientiousness.

  • Focus on the needs of followers, charismatic traits inspire group spirit, while task or relationship-oriented leaders address different aspects of group cohesion.

Power and Influence

• Effects of Power:

  • Reduces empathy and increases risk-taking behavior. Those in power may feel less inhibited and motivated to retain their position.

Hierarchies in Groups

• Social Dominance Theory: Societies create hierarchical structures, with variations in personal endorsement of these beliefs depending on cultural context.

Leaving Groups

• Members often exit groups when they feel their psychological needs are unmet, including survival, uncertainty reduction, self-esteem enhancement, or mortality management.
