Kent Berridge, Ph.D., is a professor of psychology and neuroscience. He conducts research relating to brain systems of motivation, affect, reward “liking,” reward “wanting,” emotion, fear, pleasure, drug addiction, eating disorders, and decision utility. He also studies natural syntactical chains of behavior (e.g. grooming; taste response patterns) in animals with colleague Dr. J. Wayne Aldridge. With Dr. Piotr Winkielman, he has investigated the issue of unconscious emotion in humans. The Berridge Lab in the Department of Psychology aims to improve understanding of neural mechanisms of emotion, motivation, learning and reward. Topics include the psychology and neurobiology of pleasure and desire, with implications for motivational disorders such as drug addiction and eating disorders.
