The Biphasic Alcohol Effects Scale (BAES) (Martin et al. 1993) was administered at regular intervals during and after ethanol infusion (see Figures 1-2). Ratings were analyzed beginning at the first post-infusion time point (+10 minutes after target BrAC was reached). The BAES is a 14-item self-report measure with sub-scales to assess subjective experiences of alcohol stimulation (i.e., “elated,” “energized,” “excited,” “stimulated,” “talkative,” “up,” “vigorous”; α=.95) and sedation (“down,” “heavy head,” “inactive,” “sedated,” “slow thoughts,” “sluggish,” “difficulty concentrating”; α=.91). Participants rated their experience of each effect due to alcohol on 11-point scales anchored by “not at all” (0) and “extremely” (10).
