PSYCHOLOGY 120: SOCIAL INFLUENCE AND GROUP PROCESSES

Chapter Overview

  • Key Goals:

    • Understand the nature and types of groups.

    • Examine the influence of groups on individual behavior.

Introduction to Groups

Nature and Formation of Groups

  • Definition of a Group: An organized system of two or more individuals who are interacting and interdependent, share common motives, roles, and norms regulating behavior.

  • Characteristics of Groups:

    • Social Unit: Groups consist of members who perceive themselves as part of that group, establishing unique identities.

    • Common Goals and Motives: Members work towards shared objectives or against common threats.

    • Interdependence: Actions by one member affect others, e.g., team interactions impact performance.

    • Structure: Group interactions are guided by roles and established norms, defining expected behaviors.

Examples Distinguishing Groups and Other Collections of People

  • Crowds vs. Groups:

    • Crowds lack structure and interdependence, e.g., people gathered for an accident exhibit irrational behavior.

    • Groups have defined roles and interdependent relationships, leading to structured interaction and emotional bonds.

  • Teams vs. Groups:

    • Teams feature mutual accountability and a higher commitment to group goals compared to regular groups.

Reasons for Joining Groups

  • Security: Groups provide emotional support, reducing individual insecurity.

  • Status: Membership in recognized groups enhances individuals' self-esteem and societal recognition.

  • Self-esteem: Groups foster feelings of worth; prestigious memberships bolster one’s identity.

  • Psychological and Social Needs: Groups satisfy various social requirements such as belongingness and support.

  • Goal Achievement: Collaborative efforts help achieve objectives that are unfeasible individually.

  • Knowledge and Information Sharing: Groups collectively enhance understanding and perspectives.

Group Formation: Stages and Structure

Conditions for Group Formation

  • Proximity: Regular interaction and shared environments (e.g., schools) foster relationships.

  • Similarity: Common interests and traits encourage bonding and identification with group members.

  • Common Goals: Shared objectives motivate individuals to form groups.

Stages of Group Development (Tuckman's Model)

  1. Forming: Initial uncertainty where members assess fit and establish group identity.

  2. Storming: Internal conflicts arise regarding group tasks and leadership roles, leading to hierarchy and strategizing.

  3. Norming: Development of group norms, fostering a collective identity among members.

  4. Performing: The group evolves into an effective working entity; goals are pursued collaboratively.

  5. Adjourning: Upon goal achievement or project completion, the group disbands. Group development is not strictly linear; overlapping stages are common with possible regression.

Elements of Group Structure

  • Roles: Socially defined expectations of behaviors that individuals are expected to bring to the group context (e.g., respecting elders).

  • Norms: Established standards of behavior agreed upon and enforced by group members, often unspoken (e.g., family norms).

  • Status: Relative ranking of members based on ascribed (seniority) or achieved status (expertise). Status varies within groups, influencing roles.

  • Cohesiveness: Degree of mutual attraction among group members; higher cohesiveness leads to stronger group identity but may also result in groupthink.

Groupthink and Decision-Making

Definition of Groupthink

  • Groupthink: A phenomenon where the desire for harmony overrides realistic appraisal of alternatives, leading to poor decision-making characterized by consensus.

  • Causes of Groupthink:

    • High cohesion

    • Homogeneity among members

    • Isolation from outside perspectives

    • Urgency of decision-making situations

Example of Groupthink

  • Vietnam War: Decision-making during the war exemplified groupthink due to the uncritical consensus among advisors leading to disastrous outcomes.

Strategies to Prevent Groupthink

  1. Encourage critical thinking and dissent.

  2. Present alternative options for consideration.

  3. Invite input from external experts.

  4. Solicit feedback from uninvolved parties.

Types of Groups

Primary and Secondary Groups

  • Primary Groups: Characterized by close emotional connection and direct interaction, e.g., family; foundational in establishing individual values.

  • Secondary Groups: More impersonal relationships formed based on choice, e.g., clubs or political parties.

Formal and Informal Groups

  • Formal Groups: Functions explicitly defined with structured roles (e.g., organizations).

  • Informal Groups: Less structured with spontaneous relationships (e.g., friends).

Ingroup and Outgroup Distinctions

  • Ingroup: Member group. Examples: camaraderie and shared experiences.

  • Outgroup: Non-member group, often perceived negatively. Forms of categorization influence social behaviors.

Experiments Illustrating Group Behaviors

The Minimal Group Paradigm (Tajfel's Studies)

  • Explored conditions for intergroup behavior through preferences in art.

  • Highlights the tendency for individuals to favor their assigned group regardless of arbitrary distinctions.

  • Implication: Reinforces group identities despite minimal connections.

Influence of Groups on Individual Behavior

Social Loafing

  • Definition: Reduction in individual effort when working within group settings, leading to decreased overall productivity compared to individual efforts.

  • Factors Contributing to Social Loafing:

    • Lower accountability among members.

    • Perceived irrelevance of individual contributions.

    • Lack of coordination and commitment.

Mitigation Strategies for Social Loafing

  1. Make individual efforts identifiable.

  2. Increase motivational stakes by emphasizing task importance.

  3. Strengthen group cohesiveness to encourage individual investment in group success.

Group Polarization

  • Definition: Tendency for groups to adopt extreme positions following discussion.

  • Example: Initial opinions on issues like capital punishment may become more intense after deliberation with like-minded individuals.

  • Contributing Factors: New arguments heard during discussions, validation of perspectives, and formation of ingroup identity.
