Praise for the first edition: '...manages to integrate theory, research, and illustration very nicely...all in all an excellent piece of work' - Michael Hogg, University of Queensland. '...extremely contemporary in its coverage and yet it introduces the classic works as well. The balance here is perfect' - Samuel Gaertner, University of Delaware. What are the origins of individuals' identification with groups? What are the causes and consequences of the distinction between different groups? How can intergroup conflict be reduced, whilst maintaining group loyalty and community? The first edition of "Intergroup Relations", co-authored with Norman Miller, received considerable critical acclaim. In this fully revised edition, Marilynn Brewer has added new research and ideas to provide an up-to-date and invaluable resource for all those concerned with this key area of social psychology. It is clearer than ever that group identities play a major role in human behaviour, impelling heroic action on behalf of ingroups, as well as horrific atrocities against designated outgroups. Revisions have been made that reflect the relevance of recent international events and the social psychological approaches that can illuminate and explain them. Social psychological understanding of these processes has grown as the study of intergroup relations takes centre stage within the discipline, making this a topical and timely new edition for undergraduate courses in social psychology and the wider social sciences.
