In recent decades, research in political psychology has illuminated the psychological processes underlying important political action, both by ordinary citizens and by political leaders. As the world has become increasingly engaged in thinking about politics, this volume reflects exciting new work by political psychologists to understand the psychological processes underlying Americans' political thinking and action.

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.
