Examining all aspects of groups, GROUP DYNAMICS, Sixth Edition, devotes entire chapters to such topics as the individual and the group, group formation, group development and socialization, structure, influence, leadership, performance, and intergroup relations. * Current, comprehensive coverage includes evolutionary psychology, social identity theory, individualism-collectivism, introversion/extraversion, primary and secondary groups, and the belongingness hypothesis. * A unique two-column format makes the text accessible and easy to read. * Extended case studies illustrate chapter concepts in the context of real-life groups. All 15 cases involve actual groups--not hypothetical ones--and describe documented events that occurred within the groups. * Conceptual analyses of groups are reviewed in depth, along with empirical studies that highlight important principles.
