Eating and Exercise Behavior

Research Questions

How is food-related information processed and how do these information regulate our eating behavior?
• Which role do impulsivity, reward processing and emotion regulation play concerning the control of our eating and exercise habits?
• Which changes concerning this information processing appear in the context of eating and weight disorders?

Current Projects

These are some of the projects we currently investigate:
• how the processing of food stimuli alters in the long term and after treatment of eating disorders in patients with binge eating disorder (ETBED study) and in patients with anorexia nervosa (ANET study)
• how emotions and emotion regulation strategies affect the processing of food stimuli in binge eating disorder
• Which similarities and differences occur in inhibitory control between patients showing impulsive eating and patients suffering from other impulse control deficits, i.e. substance abuse and ADHD
• whether patients with binge eating disorder can change their attention to food stimuli by using a specific training task (Antisaccade training) and whether these training effects can be enhanced by non-invasive brain stimulation (tDCS) in healthy participants
• how patients with an eating disorder perceive and evaluate their own body, using a 3D model of their own body in a virtual environment
• emotion processing in patients with chronic pain syndrome

Prospects

further studies with combinations of methods in order to combine the respective advantages of individual measurement methods
• larger longitudinal studies to examine malleability of potential dysfunctions
• further development of therapeutic interventions on the basis of experimental data
