The effect of rewarding vs. non-rewarding feedback on acquisition of a motor skill is investigated in a single blinded parallel group design. Reward consists of performance dependent monetary reward, or of knowledge of performance in selected (above average) trials.
The investigators hypothesize improved motor skill learning and higher involvement of the dopaminsrgic system under rewarding vs. non-rewarding conditions.

| Motor skill learning using an arc pointing task | temporal and spacial precision in an arc pointing task will be assessed using 5 different movement speeds during the above mentioned time periods before and after a specific motor learning programm. Learning will be assessed as change from pre-training to post training | about 10 minutes pre-training, about 10 min post training, about 24h post training |
