a: Signal intensity in the left ACC during reward outcomes averaged by groups and task runs. The Group (MDD, Control) × Run (run 1, run 2) interaction term in this region was not significant, but the effect of Run in the MDD group alone was significant, p<.005. b: Within the MDD group, decreased left ACC activation from run 1 to run 2 during reward outcomes predicted change in BDI total scores.
