Introduction to Group Behavior

This lesson introduces group behavior as a core topic in psychology: how people think, feel, and act when they are part of a group. You will learn what makes a collection of individuals into a functioning group, why group settings change behavior, and which basic concepts will help you understand later lessons on conformity, leadership, conflict, and change.

By the end of the lesson, learners should be able to define group behavior, identify major features of groups, distinguish between formal and informal groups, and explain why group context matters in real-world settings such as workplaces, classrooms, teams, and communities.
