Are we genuine or are we all playing by the rules? What makes us remember? Why do we forget? Does intelligence measure? Questions like these underlie the work of the world's greatest thinkers and researchers in the fascinating field of psychology. Written in simple language, this book is full of comprehensive yet thorough analyses, diagrams that explain complex theories, classic quotes, clever images that help us see our perceptions and opinions in a different light. In particular, the authors analyze the philosophical roots of psychology, behaviorism, psychotherapy, cognitive psychology, social psychology, developmental psychology, and differential psychology.
