Group difference in BOLD response in the vmPFC for the contrast Affective ToM>PC: (A) Graph showing the shape of the interaction in the peak voxel [−10 46 −8]. Adolescents showed a significantly greater response in this region during Affective ToM than during PC, while the adult group showed no difference between conditions. Please note that some responses are plotted as deactivations relative to fixation baseline. This does not change the interpretation of relative differences between conditions; (B) An overlay showing the main effect across all participants in left vmPFC for Affective ToM>PC (red blob) as well as the cluster showing an interaction with age group (blue blob). Age group differences are evident for the most ventral part of the vmPFC activation only. Data are displayed at a threshold of P < 0.001, overlaid on an average structural scan from all 30 participants.
