Figure 5.

Correlations between the decision bias and the neural response to real versus hypothetical reward in the outcome phase. Participants who had a larger BOLD increase to real compared with hypothetical rewards in the vmPFC showed a larger behavioral bias (positive correlation; red). In contrast, participants who showed a larger activation to real compared with hypothetical rewards in the aPFC or the dACC showed a weaker behavioral bias (negative correlation; blue). All results are cluster corrected at p < 0.05. For illustration, we also show scatter plots of these correlations (B, C) using averages within spherical ROI's with a radius of 3 voxels in MNI space.
