Author Cohen, a licensed clinical psychologist, has written a popular reference in the form of well over 1,000 questions and answers about psychology. It is another entry in Visible Ink's Handy series, joining volumes on anatomy, geology, history, law, mathematics, and more. Although Cohen suggests starting at the beginning for an overview of this vast field (56 divisions are listed under the question "What are the divisions of the American Psychological Association?") and historical context going back to the ancient Greeks, one can hardly resist jumping in almost anywhere. The book is organized into 10 sections, among them "Introducing the Basics," "Brain and Behavior," "Psychological Development across the Lifespan," and "Mental Health and Mental Illness." Sidebars ask and answer questions ranging from "What is phrenology?" and "How have laws changed to protect people from abusive psychological experiments?" to "Who are the Lizard People?" and "Who was Ted Bundy?" Black-and-white photographs appear roughly every few pages. A useful glossary, bibliography, and index conclude the book. A glaring omission in this otherwise thorough and fascinating book is coverage of sleep and related phenomena, including dreams and nightmares, which is almost nonexistent. This volume is recommended for high-school and public libraries, where it should not be confined to the reference section.
