In four parts, readers learn about how attitudes can be measured, how attitudes are shaped in the course of life, how they are changed by other people, and finally, how attitudes in turn affect our thoughts and behavior. This completely revised and updated second edition covers many recent developments and reports cutting-edge research while also addressing the classic findings and theories that advanced the field. In addition to integrating the newly emerged topics of implicit attitudes and recent models regarding the coexistence of explicit and implicit attitudes, this edition also adds chapters on social influence and resistance to persuasion. This comprehensive and user-friendly book carefully balances theoretical underpinnings and empirical findings with applied examples to enable readers to use the insights of attitude research for practical applications. Critical discussions also instigate readers to develop their own thinking on key topics.
