This volume presents current controversies that surround abnormal psychology in a debate-style format designed to stimulate student interest and develop critical thinking skills. Abnormal psychology is the branch of psychology that studies unusual patterns of behavior, emotion and thought, which may or may not be understood as precipitating a mental disorder. These topics are framed with a general summary and introduction, and a postscript or challenge questions. This work features an annotated listing of selected World Wide Web sites and an online instructor's resource guide with testing material available.
