The scientific study of mental disorder is exciting today because of new discoveries in molecular genetics, cognitive processes, neurochemistry and neuroanatomy. The study of mental disorder has evolved from a primarily descriptive discipline into a mature science that encompasses both biological underpinnings and social and developmental work. Psychopathology combines these fields of research to present a comprehensive picture of psychosis. In this important volume, distinguished investigators from these fields present new findings from their laboratories, as well as perspectives on areas of rapid growth and change. The editors also provide thoughtful overviews of four major topics in psychopathology research: brain mechanisms, thinking, development and genetics. This book will appeal to graduate students, clinicians and researchers in the fields of psychiatry, cognitive science, and neuroscience.
