Values are M(SD) for amplitude (Amp) & latency (Lat). Labels indicate the dominant sex (SJT) or emotion (EJT) portrayed in each stimulus; numerals indicate the morph level. CC=Community Control, AUD= Alcohol Use Disorder.
1
Group difference in SJT P3 amplitude (AUD < CCs)
2
Group difference in EJT P3 amplitude (AUD < CCs) that failed to persist when SJT differences considered
