Contingent Reward Responses and Relation to Contingent Learning in Experiment 1

(A) Whole-brain results for the contrast contingent- noncontingent rewards in experiment 1.

(B) Inspection of the BOLD signal at the peak coordinate in lOFC shows that this region responds selectively to contingent, but not noncontingent, rewards. Solid lines show the mean and shaded areas the SEM of the regression coefficients across subjects. The black vertical line represents the time of outcome delivery. Values are mean ± SEM of regression coefficients across subjects.

(C) Regression of the contrast in (A) against contingent learning versus PROX + SoE_Ch reveals that contingent reward responses in lOFC correlate with contingent learning behavior.

(D) Parameter estimates were extracted from the peak coordinate of the contrast in (A) and related to the different learning mechanism. The plots show that lOFC responses to contingent rewards are negatively related to noncontingent learning via PROX and SoE_Ch. The correlations are partial correlations, that is, after regressing out the effects of the respective other learning mechanisms from both parameters of interest. See also Figure S5 and Table S1.
