Differential conflict monitoring in young heavy drinkers

Aims: Difficulties in monitoring ongoing behaviour may be linked to real-life problematic drinking behaviours. Additionally, some prior research suggests females in particular display greater cognitive control deficits. In this study, we examine conflict adaptation in an Eriksen flanker task relative to sex and drinking behaviours. Method: Twenty regular binge drinkers (10 male) and 33 non-binge drinkers (18 male) completed an Eriksen flanker task while EEG was recorded. Reaction time, error rates, P2-N2 amplitude, and P3 amplitude were analysed. Results: For all measures, conflict adaptation was evidenced by a differential response to the current (congruent vs. incongruent) trials dependent on the identity of the previous trial. There were no behavioural differences as a function of Sex or Drinking Group. Conflict adaptation for P2-N2 was larger for binge drinkers, and particularly so for females. The P3 conflict adaptation effect was larger for females than males, with no difference between Drinking Groups. Conclusions: Results will be discussed in terms of individual differences in cognitive control.
