Social incentive delay task
We employed a validated social incentive delay (SID) fMRI paradigm (5). The paradigm presents condition-specific cues (positive, negative, neutral) which signal that a social reward can be obtained or a social punishment can be avoided (anticipation). Next, participants undergo a reaction time task which is followed by the presentation of a performance-dependent social reward, punishment or neutral feedback (outcome) (Figure 1B-C ).
