Effects of alcohol on the momentary moods and feelings were assessed with BAES scale (Martin et al., 1993) on three occasions during each session: upon arrival (the baseline rating), prior to entering the MEG chamber, and after the experiment. Since the baseline ratings did not differ between sessions, the subsequent ratings were expressed as the relative change from the baseline. Participants reported being significantly more stimulated before than after the task, F(1,21) = 19.2, p < 0.001. The observed interaction of condition and beverage for the estimates of “high,” F(1,21) = 7.3, p < 0.05, was due to the subjects’ reporting being more high under alcohol than placebo before the task, F(1,21) = 13.9, p < 0.001. The beverage effect on the “high” estimates was still marginally significant after the task, F(1,21) = 3.6, p < 0.05.
