Impaired inhibitory control is thought to contribute to alcohol (mis)use. However, current definitions of inhibitory control are by a failure to distinguish reactive inhibitory control from proactive slowing. To distinguish "reactive" inhibitory control and proactive slowing in heavy drinkers, and characterize associations between both constructs and individual differences in alcohol consumption. 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. 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. Within a sample of heavy drinkers, individual differences in reactive inhibitory control and proactive slowing are unrelated to individual differences in alcohol consumption.
抑制控制受损被认为是导致酒精（滥用）的原因之一。然而，目前对抑制控制的定义存在缺陷，因为它们未能区分反应性抑制控制和前摄性减速。为了区分重度饮酒者的“反应性”抑制控制和前摄性减速，并描述这两个结构与饮酒量个体差异之间的关联。60 名重度饮酒者完成了酒精摄入量的自我报告测量，然后在实验室环境中完成了两项修改后的停止信号任务和一项 AX 连续表现任务。当抑制的可能性更大时，重度饮酒者表现出了前摄性减速，但前摄性减速和反应性停止的个体差异与酒精摄入量的个体差异无关。在一个重度饮酒者样本中，反应性抑制控制和前摄性减速的个体差异与酒精摄入量的个体差异无关。
