Biphasic Alcohol Effects Scale (BAES, Martin et al., 1993) prior to drinking (at baseline), immediately before and after the task. In the alcohol session, the beverage contained 0.60 g/kg of ethanol for men and 0.55 g/kg for women and was administered as a cocktail containing 20% v/v of vodka (Grey Goose, Bacardi) mixed with orange juice. The same volume of orange juice was administered in the placebo session (Marinkovic et al., 2012). The task was administered 38 ± 9 min after the beverage was consumed. It was performed at peak BrAC levels, as the average BrAC levels were 0.044 ± 0.012% before and 0.044 ± 0.011% after the task. At the end of each session the participants were asked to rate perceived task difficulty, content of the imbibed beverage, their confidence of that determination, and how intoxicated they felt on a 1–5 Likert scale. They were asked to estimate how many alcoholic drinks were contained in the beverage starting from 0 with 0.5 drink increments. After each session, subjects were provided transportation to their homes. High-resolution structural MRI scans were also obtained from all participants in a separate session.
