Psychology as a discipline is an extremely broad field. While consistently focused on the individual, it deals with everything from brain and neurologic functions to social and environmental influences on behavior and thought. The Department of Psychology offers both a Bachelor of Arts and Bachelor of Science in psychology, minors in psychology and behavioral/cognitive neuroscience, and a Ph.D. program in clinical health psychology. The B.A. focuses more on the social aspects of the study of human behavior and psychological function, while the B.S. focuses on the biological and biochemical basis of behavior and mental function. The department's doctoral program emphasizes the contribution of research to the understanding, treatment and prevention of a wide range of health-related problems, and the application of knowledge that is grounded in scientific evidence. Students are trained in a variety of approaches and techniques for evaluating, diagnosing and treating a wide range of psychological disturbances. The clinical health psychology program is accredited by the Commission on Accreditation of the American Psychological Association (APA).
