Effects of alcohol on behavioral SST outcome variables during fMRI alcohol clamping. Alcohol and placebo responses were compared with paired t-tests (t).

	Placebo		Alcohol		test-statistics
	Mean	(SEM)	Mean	(SEM)	placebo vs. Alcohol
SSRT (ms)***	207.6	(6.3)	226.0	(8.1)	t(41) = -4.07, p<.001
Probability of inhibition (%)**	48.2	(0.5)	46.2	(0.8)	t(41) = 2.97, p=.005
