Author Pamilla Ramsden presents a thorough understanding of abnormal psychology for undergraduate students with a focus on the integration of psychology, biology and health. Understanding Abnormal Psychology: Clinical and Biological Perspectives goes beyond a descriptive overview of clinical disorders to provide a critical appreciation of the multifaceted aspects of mental illness.
