Group Dynamics

Personality and Social Psychology

Group dynamics is a system of behaviors and psychological processes occurring within a social group, called intragroup dynamics, or between social groups, called intergroup dynamics. The field is studied across multiple disciplines and applied to decision-making, the transmission of disease, group therapy, the adoption of innovation, and other processes in which the structure and behavior of a group shapes outcomes for its members.

Facts
Central Question
Group dynamics asks how systems of behavior and psychological process arise within a social group and between social groups, and how a group's emergent structure can be more than the sum of what its individual members bring to it. 1
Key Debate
Group dynamics rests on Max Wertheimer's 1924 Gestalt claim that a group's properties are fixed by the intrinsic structural laws of the whole rather than by summing its individual members, a holist premise that puts the field at odds with any account that tries to explain group behavior by adding up individual psychology alone. 1
