The Social Psychology of Behaviour in Small Groups covers theories of group behaviour and their application in organizational psychology. Topics include the structure and formation of groups and the roles that individuals play within groups, as well as more applied areas such as co-operation and conflict, teamwork, leadership and decision-making in small groups. Throughout the book theory, research and concepts are applied to real-life and everyday social behaviour. The book is well illustrated and includes many mental exercises to engage the reader. Donald Pennington has provided a lively, accessible and systematic text suitable for undergraduates studying social psychology and those studying organizational psychology on psychology and business studies courses.
