Dr. Kent Berridge received his Ph.D. from the University of Pennsylvania and is currently the James Olds Collegiate Professor of Psychology and Neuroscience at the University of Michigan. He has been a Guggenheim Fellow, a Fulbright Senior Scholar and recipient of the Early Career Award from the American Psychological Association. Dr. Berridge's research focuses on the role of reinforcing and affective properties of rewards, addiction, and the brain mechanisms of pleasure and reward. He has contributed to behavioral and neurobiological distinctions between "wanting" and "liking" rewards. His research has been funded by the National Institute on Drug Abuse, National Institute on Alcohol Abuse and Alcoholism, and the National Institute of Neurological Disorders and Stroke. Dr. Berridge serves on several editorial boards, including the Journal of Neuroscience, Behavioral Neuroscience, and Cognitive Affective & Behavioral Neuroscience. |
Abstract: Take-home idea: Behavior analyses reveal surprising psychological features and neurobiological mechanisms underlying intense motivations of reward-related "liking" and "wanting," and relations to negative-valence motivations of fear and disgust. Abstract: Clinical disorders of addiction, binge eating, depression and schizophrenia often involve intense psychopathological mood or motivation states. So it is of interest to understand how limbic brain circuits (involving nucleus accumbens) generate intense motivational states of reward "wanting" and "liking," and also of fearful or aversive states. Behavioral analyses and affective neuroscience studies indicate that "wanting" a reward is generated by a different brain mechanism from "liking" the same reward. The difference between wanting versus liking has implications for understanding addiction and related disorders. Yet surprisingly, desire and fear can both can both be generated by an overlapping mechanism, which may have different modes for each. This lecture will address such dissociations and convergence in affective brain mechanisms. |
