Field of Research
Our group is interested in psychobiological mechanisms in the regulation of eating behavior, especially the framework of impulsivity, including concepts such as reward sensitivity, inhibitory control and emotion regulation. We are studying these mechanisms across the whole spectrum of body weight, especially in extreme weight conditions such as underweight, as it is seen in the eating disorder anorexia nervosa, and overweight/obesity. We are aiming at a translation research approach by using results from experimental studies as a basis for the development of novel and innovative treatment/training approaches for eating and weight disorders. A second focus of our work is on body image, also especially in extreme weight conditions, and how this can be assessed with novel techniques, e.g. using virtual reality applications.
In our experimental studies, we are using different psychophysiological and brain imaging techniques, assessing e.g. attentional processing of food cues or inhibitory control in response to food cues. Methods include e.g. eye tracking, EEG, EMG, MEG, NIRS and fMRI.
