Affect & Decision-Making in Health and Disease

 

The ability to use information to adaptively guide behavior is central to intelligence. My work describes the role of affect in this process. In this talk I will present our recent research characterizing the influence of affect on how humans gather, and use, information to make predictions. First, I will present a framework for understanding how people decide whether to seek information. One key component is whether the information is likely to produce a positive or negative affective response. This influence of valence on information-seeking is captured by brain regions along the dopamine reward pathway. The findings yield predictions about information-seeking behavior in disorders in which the dopamine system malfunctions. We have begun to test these predictions, aiming to use measures of information-seeking to facilitate early detection, monitoring and treatment selection for psychopathology. Second, I will show that learning in response to positive and negative information involves distinct mechanisms. This segregation of function allows for flexibility in how positive and negative information influence beliefs and actions in different environments, for instance as a function of the level of threat. Finally, I will describe how these processes are altered across the life-span and in clinical depression.

 

A pizza lunch will be served at 11:45am. The seminar will begin at 12:00pm.
