The post-hoc ANOVA confirmed a main effect of FH (p’s<0.023) on connectivity change for all ROIs. There was a valence x FH interaction (F67,2=10.9, p=0.003) for incentive connectivity change between right NAcc and right lingual gyrus; post-hoc t-tests revealed that only in FH−, NAcc-lingual connectivity had more significant change with reward rather than loss vs. neutral conditions (t=3.22, p=0.004). There were no main effects of valence (p’s>0.07) or interactions with FH (p’s>0.19) on connectivity with other ROIs. Additional post-hoc analyses, excluding subjects with any diagnosis (FH−, n=2; FH+, n=6), confirmed the main effect of FH on connectivity change for all ROIs was not driven by diagnoses (p’s<0.048).
