Participants attended an initial (nondrinking) lab session where they completed the self-report measures as well as a battery of cognitive tasks germane to the aims of the larger study from which the current data were derived. One-to-three weeks later (M = 19.1 days) participants returned for a second (alcohol challenge) session. Participants were asked to eat a light meal 2–4 hours before their appointment. After providing informed consent, women were given a urine stream pregnancy test to self-administer (none tested positive); men were also asked to void the bladder. Participants completed a baseline BAES and subjective intoxication assessment, and then were randomly assigned to receive an active placebo (diluted [10-proof] vodka and tonic water; 0.04 g/kg ethanol), or alcohol beverage (100-proof vodka and tonic water; 0.80 g/kg ethanol for men [0.72 g/kg for women]; average peak breath alcohol concentration [BrAC] = 0.082, SD = 0.012). In both conditions beverages were mixed in front of participants, their contents poured from Smirnoff® vodka and Schweppes® tonic bottles, and divided into three equal-sized drinks, consumed at the rate of one every 8 min.
