Group Processes

Understanding Group Dynamics

Overview

Group processes involve the psychological mechanisms and dynamics that occur when individuals function as part of a group. Humans are social animals and tend to identify and behave differently when they belong to groups compared to when they are alone. The study of group processes examines how group membership influences thoughts, feelings, and behaviours.

Study Outline

Key areas covered in the analysis of group behaviour.

1

Defining a Group

Collection of two or more individuals who interact and influence one another.
2

Social Identity Theory (SIT)

How group membership affects self-concept (Tajfel and Turner).
3

Norms, Roles & Cohesion

Shared expectations and bonds linking group members together.
4

Group Decision-Making

Analysis of polarization and groupthink phenomena.

SIT Key Processes

Social Identity Theory (SIT) relies on three fundamental psychological mechanisms:

1

Social categorization

Dividing the social world into groups, such as nationality, age, gender. This simplifies the environment and helps individuals understand their social world.
2

Social identification

Adopting the identity of the group one has categorized oneself as belonging to, including conforming to group norms and values.
3

Social comparison

Comparing one’s in-group positively against out-groups to enhance self-esteem.

Key Finding: In-Group Favoritism

💡

Tajfel's Insight: Tajfel’s “minimal group experiments” showed that simple categorization without any meaningful interaction can trigger in-group favoritism, proving that group identity alone can influence behaviour deeply.

Decision-Making Processes

Differentiating two critical group decision pitfalls.

🤔
Wait, how is Group Polarization different from Groupthink?
🦉
Group Polarization amplifies members’ initial attitudes, making decisions more extreme. Groupthink is when the desire for harmony suppresses dissenting opinions, leading to poor decisions.

SIT Utility vs. Limitations

✅
The Utility (Applications)SIT explains: Prejudice and discrimination, Nationalism and ethnocentrism, Social movements and collective action, and Organizational behaviour.
❌
The Limitations (Critiques)It may underestimate the role of individual differences; Overemphasis on in-group bias; Some research focuses strongly on laboratory contexts that lack ecological validity.
