Greater externalizing tendencies predicted less error-related brain activity in acutely abstinent smokers. (left) Error commission was associated with increased activation notably in the right and left insula and dACC. (middle and right) Correlations between self-reported externalizing tendencies (ESI score) and regional error-related activity (% BOLD Δ) among smokers (middle column) and nonsmokers (right column). Higher ESI scores indicated less right insula recruitment following error commission among smokers, but not nonsmokers as indicated by a significant ESI x GROUP interaction. A similar although non-significant outcome was observed when considering left insula activity. Higher ESI scores also indicated less dACC recruitment following errors among smokers.
