Amygdala BOLD response is modulated by both temperament and expectation. a For the interaction of Temperament × Expectation, there were significant clusters (p < .05, corrected) in both the left and right amygdala. Activation maps show t-values, threshold at p < .05 with cluster size > 11 voxels and masked to show the amygdala region of interest. The color bar represents t values. b, c Bar graphs show percent signal change values for the left (b) and right (c) amygdala clusters. Error bars represent standard error of the mean. Post-hoc analysis of variance confirmed the interaction for both the left (p = .003) and right (p = .02) amygdala. Asterisks indicate significant differences (p < .05) in post-hoc t tests within each temperament group
