Written by well-known sociologists John D. DeLamater, Daniel J. Myers, and Jessica L. Collett, this fully revised and updated edition of Social Psychology is a highly accessible and engaging exploration of the question "what is it that makes us who we are?". With hundreds of real-world examples, figures, and photographs and grounded in the latest research, the text explores such topics as self, attitudes, social influence, emotions, interpersonal attraction and relationships, and collective behavior. The book also explains the methods that social psychologists use to investigate human behavior in a social context and the theoretical perspectives that ground the discipline. Each chapter is a self-contained unit for ease of use in any classroom.
