After beverage consumption and following a 5-min absorption period, BrAC, BAES, and subjective intoxication measures were administered every 5–6 min until BrAC reached 0.065% for alcohol participants (or after one BrAC measurement for placebo participants), at which time the cognitive task battery was initiated. These measures were re-administered after every other cognitive task (approximately every 20 min). Upon completion of the cognitive tasks, BrAC and subjective effects were assessed every 5 min until BrAC descended from peak to 0.075%, at which time the cognitive battery was completed again; as during the ascending limb, BrAC, BAES and subjective intoxication were assessed after every other task. Upon completion of the second round of cognitive tasks, placebo participants were debriefed and dismissed. Participants in the alcohol condition were retained in the lab until they were sober (BrAC 0.02%; see NIAAA, 2004).
