Groups in Contact: The Psychology of Desegregation uses the contact hypothesis as a point of departure and provides new data obtained in a variety of social contexts. The contact hypothesis states that attitudes toward a disliked social group will become more positive with increased interpersonal interaction. The various chapters provide a picture of the desegregation process as a complex interplay between the cognitive processes within the individual and the structural features of the social environment. What emerges is an expanded theory of contact based on social categorization and social comparison processes. The book is organized into three parts. The chapters in Part I deal with issues of intergroup contact in a wide range of cultures and settings, each focusing on a particular social or political factor that influences receptivity to intergroup interaction and affects its outcomes. The chapters in Part II review the effects of specific interventions that have been introduced into desegregation settings with the intent of improving intergroup acceptance in those settings. Part III provides a systematic integration of the preceding chapters within a common theoretical framework. Although this book is written primarily from the perspective of social psychology, it is intended for students of intergroup relations in all disciplines. It was also written with policymakers, as well as social science researchers, in mind.
