Lecture 16- Intra-Group Processes Summary

Intra-Group Processes: Key Concepts

What is a group?

  • Definition varies: includes families, organizations, nationalities, etc.
  • Question of universality in defining 'groups' as a single concept.

Entitativity

  • Refers to the perceived 'realness' or coherence of a group.
  • Factors influencing entitativity:
    • Cohesiveness
    • Interconnectedness
    • Similarity
    • Common goals
    • Importance of the group.
  • Groups ranked by entitativity:
    1. Intimacy groups: families, close friends.
    2. Task groups: colleagues, project teams.
    3. Social categories: gender, religion.
    4. Loose associations: neighbors, hobby groups.

Social Facilitation vs. Social Inhibition

  • Performance can improve (social facilitation) or decrease (social inhibition) due to the presence of others.
  • Key studies:
    • Triplett's study showed that cyclists perform better in the presence of others.
    • Performance influenced by task complexity.

Drive Theory (Zajonc, 1965)

  • Presence of others increases arousal which enhances dominant responses (well-learned tasks) but may hinder performance on unlearned tasks.

Evaluation Apprehension Theory (Cottrell, 1972)

  • Focus on evaluation of performance by others rather than just presence.
  • Cottrell et al (1968) study:
    • Participants performed tasks with/without audience. Effects of 'evaluation apprehension' noted.

Social Loafing

  • Defined as reduced individual effort in a group task.
  • Ringlemann Effect (1913): individuals exert less effort when in larger groups due to coordination and motivation loss.
  • Group tasks often perform below potential due to:
    • Process loss: interference and coordination challenges.
    • Motivation loss: reluctance to exert effort as others are present.

Factors Contributing to Social Loafing

  • Output equity: If one perceives others loafing, they may reduce their effort to match.
  • Evaluation apprehension: Group tasks can lead to anonymity, reducing motivation.
  • Performance standards: Clear goals help minimize loafing.
  • Social impact: Group size increases anonymity and may reduce personal responsibility.

Summary

  • Group definitions vary based on perspective.
  • Entitativity is crucial for understanding group dynamics.
  • Group performance can be impacted positively or negatively by individual behaviors, with social loafing being a significant factor affecting overall effectiveness in group tasks.
