Dreams puzzled early man, Greek philosophers spun elaborate theories to explain human memory and perception, Descartes postulated that the brain was filled with "animal spirits," and psychology was officially deemed a "science" in the 19th century. In AN INTRODUCTION TO THE HISTORY OF PSYCHOLOGY, author B.R. Hergenhahn shows you that most of the concerns of contemporary psychologists are manifestations of themes that have been part of psychology for hundreds--or even thousands--of years. The book's numerous photographs and learning tools, along with its coverage of fascinating figures in psychology, engage you and will help you understand the material in each chapter. Chapter summaries, discussion questions, end-of-chapter glossaries, and a Book Companion Website will all help you prepare for success on your next exam.
