In 13 chapters, world-class scholars present new in-depth work exploring public opinion, social movements, attitudes toward affirmative action, the behavior of political leaders, the impact of the 9/11 attacks, and scientists’ statements about global warming and gasoline prices. Also included are studies of attitude strength that compare the causes and consequences of various strength-related constructs. This volume will appeal to a wide range of researchers and students in political psychology and political science, and may be used as a text in upper-level courses requiring a scholarly and contemporary review of major issues in the field.
