Various signals are present in the aPFC during the outcome phase. Different signals are present in aPFC that are consistent with a role in overcoming a bias to stay with the current choice when there is real rather than hypothetical reward. A, First, aPFC activity increases when rewards are real (pink) and participants with a stronger increase are better at overcoming the behavioral bias (blue). B, Second, the representation of effort magnitude outcomes increases in aPFC when reward is real (yellow). We also show the relative effort magnitude outcome contrast (red) used to identify our aPFC ROI (used for time courses in Fig. 6).
