All feedback conditions vs. baseline
To investigate the consistency in neural activation in the general contrast of social evaluation (positive, neutral and negative feedback vs. fixation) across the three samples we conducted the analyses in two steps. First, patterns of activations found in the pilot sample were masked with anatomical masks and these ROIs were then used to extract PE values from the test sample. Secondly, we repeated this procedure with the test sample as starting point. The ROIs from the test sample were used to extract PE values from the replication sample. This was done because some regions might not show up in samples as small as our pilot sample.
Functional clusters from the general contrast of social evaluation were masked with anatomical regions. That is to say, we overlapped all functional clusters from the whole brain contrast with anatomical regions from the
