This supplement supports the development of critical thinking skills necessary to success in the introductory psychology course. The chapter sequence mirrors the organization of the typical introductory psychology course. In the first chapter, the author identifies seven characteristics of critical thinkers, and in the following chapters he dissects a challenging issue in the discipline and models critical thinking for the reader. Each chapter concludes with an analysis of the process, exercises for the student, and extensive references. This useful volume supports the full semester of the course.
