- Study type
- Observational
- Interventions
- Group 1: The task for the patients is to throw a ball 300 times against a wall. During the experiment patients are wearing different prism-classes to test visuomotor adaption. In one specific experimental phase patients receive reward prediction errors to trigger reinforcement learning. Group 2: The patients in the controllgroup perform the same experimental procedure. However this group differ with regard to the feedback signal. Patients adapt their motor commands based on sensory prediction errors (error-based learning).
