The literature is equivocal about the effect of alcoholism on early ERP latencies to EFE. Maurage et al. did not find an effect of alcoholism on the P1, N100 or N170 latency to faces displaying anger or disgust, but did find longer latencies of these waves in a study of anger and sadness (Maurage et al.). An earlier study by the same group found increased latencies of P1 and N170 in alcoholics (Maurage et al., 2007b). All the participants above were short-term abstinent alcoholics (2–3 weeks abstinent).
