Fig. 4.

(A) A sagittal slice showing an area in the dACC significantly correlated with the degree of cognitive dissonance (CDI) during Preference task 2, but not during Preference task 1 (P < 0.001 uncorrected). The scale shows the t values. (B) β-Values extracted from the peak voxel at the dACC (x = 12, y = 30, z = 46) for Preference task 1 and Preference task 2 (from GLM 4). Note that exactly the same CDIs for the same food items were modeled in both Preference tasks 1 and 2, but CDIs were significantly correlated with the dACC activity only during Preference task 2. ***P < 0.001 (one-sample t test, one-tailed). Error bars indicate SEM.
