This second edition of this successful textbook has been completely rewritten, updated and revised and now contains some of the most recent research and theory on most areas of social psychology. The emphasis on social cognition provides a unifying theme and topics covered include material on conflict and cooperation, including sections on prejudice, aggression and helping behaviour. How we attribute personality characteristics from observation of the behaviour of other people and ourselves is examined, along with leadership, group decisions and different types of relationships. Fully illustrated and written in an easily accessible form, each chapter provides learning objectives and self assessment questions to provide a comprehensive introduction.
