Abnormal Psychology broke ground in its First Edition, changing the way instructors thought about and taught this course. The new edition retains the text's engaging and innovative systems approach, integrating the biological, psychological, and social perspectives in one concurrent story. Scientific methods are presented in a clear and non-threatening manner, and are based on the most current research. Detailed case studies open each chapter, and historical background information is included to give students interesting, “real-life” examples of abnormal behavior, while illustrating the fact that this book is not about “them.” It's about all of us.
