The second edition of Social Psychology remains the only conceptually integrated book in the field, and provides a clear synthesis of the cognitive and social, individual and group influences that shape social behavior. Moreover, it is the only textbook to fully integrate the North American focus on individual behavior with the European focus on group behavior. Instructors have welcomed its unusually broad perspective, its fresh and interesting use of unifying principles, and its state-of-the-art currency. Students have appreciated its lively personal style and accessibility, its innovative learning aids, and its immediate relevance to their lives. The new edition takes account of the significant advances that have been made in the field over the past few years, and incorporates other improvements based on feedback from users of the first edition. This edition has been thoroughly updated and includes significant new material on the automatic activation and suppression of stereotypes,interdependence processes in close relationships, the latest work on social identity (much of it from Europe), expanded coverage of group interaction processes, and the latest work on implicit attitudes. Based on extensive feedback from users of the first edition and experts in the field, the material covered in the final three chapters has been reorganized into three new chapters on interaction in groups, aggression and conflict, and helping and cooperation. The learning aids have been refined in light of feedback from users to make them clearer and more user-friendly to students. New in this edition are the annotated suggestions for further reading at the end of each chapter to guide students interested in following up particular topics in more detail.
