1. Evidence for behavioral control modulation that varies as a function of time during cognitive regulation.
Evidence for behavioral control modulation that varies as a function of time during cognitive regulation. A–C, vmPFC (A), left dlPFC (B), and right dlPFC (C) regions in which a linear contrast of correlation with behavior in each condition (DISTANCE = −1; NATURAL = 0; INDULGE = +1) showed a significant interaction with time (early evaluation vs late response initiation). The hot colors indicate greater correlation with behavior in INDULGE compared with DISTANCE. The cool colors indicate the opposite. D–F, Time course of activation in each condition (blue, DISTANCE; green, NATURAL; yellow, INDULGE). Parameter estimates indicate the average strength of association with bid at each time point, and encompass a 20 s window beginning at onset of instruction (see Materials and Methods for details). The dashed vertical lines demarcate trial events and are shifted forward 5 s to account for hemodynamic lag. The horizontal double lines at the top of the plots indicate time points at which two conditions differ (p < 0.05). The line colors indicate the conditions being compared. Transparent areas indicate SEM.
