The study consisted of two measurements (For the behavioural task in the VR, the patients were equipped with the HMD and completed practice trials to get familiar with operating the system. An exemplary trial is shown in Fig. Visualization of a trial of the condition “food”. The target stimulus to be grasped was a chocolate cupcake with pink icing. The distractor stimulus was a beachball. After matching the initial hand pose with the standardized hand pose, the crosshair of the HMD had to be aligned with the fixation cross for 1 s. After 400 ms, target and distractor stimulus were presented on the left and right table. The image was previously used by Max SM, Schroeder PA, Blechert J, Giel KE, Ehlis A-C, Plewnia C (2021) Mind the food: behavioural characteristics and imaging signatures of the specific handling of food objects.
