Primary Outcome Measures

Name	Time	Method
the primary measure of the study is the feedback-related negativity (FRN), an event-related potentials component assessed by means of electroencephalography. It is scored as the maximum EEG amplitude difference between negative and positive feedback processing at frontocentral elecrodes on the scalp. We hypothesize that the FRN is lower in the patients relative to controld, but only for immedaite, not for delayed feedback.

Secondary Outcome Measures

Name	Time	Method
The second dependent variable is the P300, another EEG-component, separately assessed for negative and positive immediate and delayed feedback at frontal and parietal electrode sites.
