Group dynamics refers to the attitudinal and behavioral characteristics within and between social groups. It concerns how groups form and function, as well as the psychological processes that occur within groups. Key factors that affect group dynamics include communication processes, interaction patterns, interpersonal attraction and cohesion, social integration and influence through norms and roles, the exercise of power and control, and the development of group culture. Understanding group dynamics can provide insights into decision-making, the spread of ideas, and forms of social prejudice.
