"This book convincingly shows how the study of groups, particularly the interface of inter-group and intra-group processes, implicates such cognitive and intra-personal foci as attitudes, prejudice, and social cognition. At last we have an integrated volume which returns social phenomena to the intersect of personal and inter-personal processes. This is, or should be, the essence of social psychology, and this volume articulately reminds us that we and our social context (not our cognitive processes alone) determine our behaviour."—Martin Kaplan, Ph.D., Department of Psychology, University of California
