Abstract

<i>Background:</i> Impaired inhibitory control is thought to contribute to alcohol (mis)use. However, current definitions of inhibitory control are <i>over-simplified</i> by a failure to distinguish reactive inhibitory control from proactive slowing. <i>Objectives:</i> To distinguish "reactive" inhibitory control and proactive slowing in heavy drinkers, and characterize associations between both constructs and individual differences in alcohol consumption. <i>Methods:</i> Sixty heavy drinkers completed self-reported measures of alcohol consumption, followed by two modified Stop-Signal tasks and an AX-continuous performance task in a laboratory setting. <i>Results:</i> Heavy drinkers demonstrated proactive slowing when inhibition was more likely but individual differences in proactive slowing and reactive stopping were unrelated to individual differences in alcohol consumption. <i>Conclusions/Importance:</i> Within a sample of heavy drinkers, individual differences in reactive inhibitory control and proactive slowing are unrelated to individual differences in alcohol consumption.
