Habitual vs. Goal-Directed Behavioural Control in Obesity (Dr. Annette Horstmann, completed)

Studies suggest that obese people tend to actions and behaviors that lead to quick rewards. This can promote overweight if this also applies to the eating behavior. The researchers examine which role the brain plays in reward orientated, and respectively more controlled behavior. Thereto the reactions of the brain in over- and normal-weight participants are measured in image, smell and taste tests. The tests are associated with learning and decision tasks, because a different reaction to such test stimuli could explain different behaviors. The aim is to better understand the neurobiological basis of decision making. This may be helpful to develop special therapies or behavior trainings.
