Bernd Figner (Postdoc 2006-2010)

Dr. Figner's is now Assistant Professor at the Radboud University in Nijmegen. His research is concerned with the interplay of affective and deliberative processes in decision making, specifically in the areas of risky decision making and intertemporal choice. This work investigates which situational and personal characteristics lead to differential involvement of affective versus deliberative processes (e.g., static versus dynamic choice situations), how affect-based versus deliberative decisions differ in the underlying processes such as information use, and how the resulting decisions differ (e.g., with respect to risk taking or increased impulsiveness). Dr. Figner studies the development of these processes across the lifespan, with a focus on the changes that occur during the transitions from childhood to adolescence and from adolescence to adulthood. He uses behavioral and physiological measures as well as brain imaging and brain stimulation techniques. He is a research scientist at the Center for Decision Sciences and the Department of Psychology, sponsored by grants from the US and Swiss National Science Foundations.  For more information, click here.
