Non-intoxicated disinhibition is p-inhibition failure following placebo. Sensitivity to alcohol-induced disinhibition was calculated by subtracting participants’ p-inhibition failures in the placebo condition from p-inhibition failures following alcohol. Larger sensitivity scores represented greater alcohol-induced disinhibition. All variables were standardized prior to regression models, and Sex was dummy coded (female = 1, male = 2).
