Social psychology and politics are intricately related, and understanding how humans manage power and govern themselves is one of the key issues in psychology. This volume surveys the latest theoretical and empirical work on the social psychology of politics, featuring cutting-edge research from a stellar group of international researchers. It is organized into four main sections that deal with political attitudes and values; political communication and perceptions; social cognitive processes in political decisions; and the politics of intergroup behavior and social identity. The contributions address such exciting questions as how do political attitudes and values develop and change? What role do emotions and moral values play in political behavior? How do political messages and the media influence political perceptions? What are the psychological requirements of effective democratic decision making, and why do democracies sometimes fail? How can intergroup harmony be developed, and what is the role of social identity in political processes? As such, this volume integrates the role of cognitive, affective, social and cultural influences on political perception and behavior, offering an overview of the psychological mechanisms underlying political processes. It provides essential reading for teachers, students, researchers and practitioners in areas related to power, social influence and political behavior.
