Note. Analyses include alcohol dose and session number, both ns; variables were not centered; Trails scores are t-scores; urge is measured on a 0 (low) to 100 (high) scale; change in Trails B = Trails B t-score postdrink administration minus Time 1 Trails B t-score; change in urge = urge postdrink administration minus Time 1 urge score.
