a) Accuracy difference scores representing the group by task interaction, in which patients with schizophrenia demonstrate a greater decrease in performance compared to controls in proactive (AX-CPT = AX Hits minus BX False Alarms) compared to reactive (Stroop = Congruent Hits minus Incongruent Errors) control. b) Horizontal slice view of a priori bilateral DLPFC ROI. c) Beta values (AX-CPT B–A and Stroop I–C) from a priori bilateral DLPFC ROI representing the group by task interaction. Error bars reflect standard error of the mean.
