Table 1 shows demographics, alcohol/drug use measures, and psychological measures for NSAC and LTAA. NSAC and LTAA did not differ by age or proportion of women in each group. NSAC had slightly more years of education compared to LTAA (15 vs. 14 yrs, η2 = 13.6, p = 0.02) and not surprisingly there were more LTAA with a lifetime history of smoking (12/20 vs. 3/21, odds ratio = 9, p = 0.005). LTAA drank an average of 189 ± 165 standard drinks/month over their lifetime with a peak use of 334 ± 263 drinks/month. LTAA had been abstinent an average of 2749 ± 2933 days (about 7.5 yrs, min/max 1.6/32 yrs). EEG and fMRI testing sessions were 6.56 ± 8.24 weeks apart for NSAC, and 4.65 ± 9.48 weeks for LTAA (η2 = 1.2, NS), with a range of 0–34 weeks between sessions. LTAA were more prone to social deviance as evidenced by lower CPI-sociability scores (17 vs. 22, η2 = 29.7, p < 0.0001), were more impulsive (9 vs. 3, η2 = 37.3, p < 0.0001), and had greater
