One of the most globally recognised sub-disciplines of social psychology is the field of intergroup relations, which has a strong relationship with both sociology and political science given its preponderance with themes such as prejudice, discrimination, multiculturalism and the relationship between social groups. This new four-volume major work presents a comprehensive and authoritative collection of both classic and contemporary readings in intergroup relations.Each volume is opened by an introductory chapter which provides the reader with an overview of the primary topics covered therein, and the rationale behind the editor’s selection.Whilst the volumes are organized around the broad research themes of intergroup relations, the papers are carefully structured so that together they tell the story of how intergroup relations research has evolved within social psychology. Volume One: Cognitive Processes Volume Two: Motivation and Ideology Volume Three: Emotion, Neuroscience and Evolution Volume Four: Improving Intergroup Relations
