Simple reaction time
There was a significant condition by time interaction for simple reaction time (ms) (At 100 min, reaction time (ms) increased (poorer performance) in the alprazolam (Mean change from placebo across conditions (alcohol, alprazolam and combined alcohol and alprazolam) and time (30 and 100 min) for simple reaction time (ms), choice reaction time (ms), numeric working memory reaction time (ms), immediate word recall accuracy (%), delayed word recall accuracy (%) and picture recognition accuracy (%). Errors bars indicate ± standard error of the mean (SEM).
