An examination of Hare's findings about groups, teams, and social interaction, this book shows how these findings can be placed in the context of several theories, and discusses some applications that can be constructed for the analysis of various kinds of social situations. Part I brings together the literature on small workgroups from laboratory studies by social psychologists and practitioners in organizational development. Part II presents four theories of social interaction with examples of applications: functional, dramaturgical, exchange, and SYMLOG. The final chapter brings together features of these theories in a category system for the observation of groups.
