Instrumental learning and Pavlovian to instrumental transfer in obesity (Prof. Dr. Jane Neumann, completed)

Instrumental learning and behavior mean adequate behaviors e. g. a healthy food choice, and the ability to react appropriately in a given situation. In obesity there may be a deficit in instrumental learning and behavior. The so called “Pavlovian-to-Instrumental Transfer” (PIT) is the influence of positive and negative stimuli from the environment onto the instrumental behavior. This project examines obesity- and gender-related alterations in instrumental learning and the influence of stimuli on instrumental behavior. The examinations will look at the behavioral and neuronal aspects. Normal- and overweight study participants do tests, in which they learn the association of special stimuli with behaviors and reward.

By magnetic resonance tomography the activities in the brain will be measured. This study may contribute to clarify the obesity-specific deficits in instrumental learning and decision-making as well as the specific brain regions. This may help to develop new behavioral or pharmacological therapy approaches.
