Correlations between PTSD symptom clusters and response to positive vs neutral Affective Stroop distractor trials, voxelwise p < .001. (a) Reexperiencing positively correlated with dACC (MNIx,y,z = 0,23,22) activation. (b) Avoidance positively correlated with right parahippocampal gyrus (MNIx,y,z = 9,−10,−23) activation. (c). Hyperarousal correlated with middle cingulate cortex (MNIx,y,z = 0,−19,34) activation.
