Psychology Psychology is designed to meet the scope and sequence for the single-semester introduction to psychology course. For many students, this may be their only college-level psychology course. As such, this textbook provides an important opportunity for students to learn the core concepts of psychology and understand how those concepts apply to their lives. The authors strive to make psychology, as a discipline, interesting and accessible to students. A comprehensive coverage of core concepts is grounded in both classic studies and current and emerging research, including coverage of the DSM-5 in discussions of psychological disorders. The text incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.
