This highly readable volume illuminates the interplay among biological, psychological, and social-contextual processes in the development of such prevalent problems as depression, schizophrenia, ADHD, dyslexia, and autism. Leading developmental scientist Bruce F. Pennington explains the variety of methods currently being used to investigate the mindbrain connection, including behavioral and molecular genetics, studies of brain structure and function, neuropsychology, and treatment studies. Shedding new light on where mental disorders come from, how they develop, and why they are so common, the book also examines implications for treatment and prevention.
