An alcohol cue reactivity study (Petit et al., 2012) on binge drinkers reported enhanced P100 amplitude for alcohol-related images versus neutral images. This finding is similar to that seen in adult alcoholics and was not observed in control subjects. The later components (N2 and P3) were not affected, suggesting an early attention bias for alcohol-related cues. Maurage et al. (2012), in a most detailed study on binge drinking and its ERP correlates, used a face detection oddball task to evaluate both early and late cognitive processes, effect of comorbid conditions, and alcohol consumption pattern and amount. The authors reported massive ERP impairments from the early P100/N100, N170/P2, N2b/P3a, and P3b. Alcohol intake amount and specific binge-drinking patterns were also associated with these impairments.
