The Social Psychology of Inclusion and Exclusion examines the psychology of inclusion and exclusion within relationships between individuals, small groups, and large scale social categories such as nationality and ethnicity. Leading international experts in social psychology explore the impact of being excluded on people"s emotions, actions, and reactions. They examine the circumstances that surround social exclusion, the conditions that lead people to exclude others from their groups, and ways that the negative impact of social exclusion can be reduced. As well as setting out the latest theories and evidence, the contributors also address the practical and policy implications of their work. The coverage ranges from the ostracism of individuals within small groups; the impact of not belonging on emotions, thoughts and actions; the stigmatization of individuals who are rejected by society; the analysis of intergroup segregation and exclusion in Northern Ireland; the way that communication affects our images and openness to inclusion of ethnic outgroups; the way deviants are dealt with by other group members; and the role of social exclusion in delinquency. The volume will be of interest to social psychology researchers, as well as final year undergraduate students and graduate students on a variety of social psychology courses. Its breadth will also appeal to students of intercultural relations, sociology, political science, and even social and public policy. It will also serve as a useful resource for decision makers and social policy officials, and as a tool for social scientists who conduct research on social inclusion and exclusion.
