Note: PAD: patients with alcohol dependence; HC: healthy controls; %go and %stop: percentage of successful go and stop trials; SSRT: stop-signal reaction time; PES: post-error slowing; all numbers are mean ± standard deviation. P values of the interaction effect are all based on 2-way ANOVA: subject by SSRT group.
