酒精中毒可以抑制对压力源的负面情感反应。最近，有人提出，这些急性抗焦虑作用的酒精可能会延伸到阻尼的负面情感反应，错误委员会在认知控制任务。然而，这一说法缺乏实证验证。在一项需要努力的认知控制任务中，测试酒精对错误的负面情感反应的急性影响。健康的年轻成年社交饮酒者（N=96 [49名女性]，21-36岁）在完成埃里克森侧翼任务之前被随机分配饮用酒精（0.80 g/kg; n = 33 [15名女性]），活性安慰剂（0.04 g/kg; n = 33 [18名女性]）或非酒精对照饮料（n = 30 [16名女性]）。皱眉肌（Corr）激活，一个心理生理指标的负面影响，跟踪整个任务。两个神经生理反应的错误，错误相关的负性（ERN）和错误的积极性（Pe），也进行了测量。在对照组和安慰剂组中，错误的行为增加了Corr的激活（程度较小），但在酒精组中没有。在对照组中，错误诱导的Corr激活与ERN和Pe偶联，但在酒精和安慰剂组中则不然。在任何组中，错误诱导的Corr激活都不与错误后的性能调整相关联。酒精抑制与错误相关的负面影响的能力得到了验证。研究还表明，安慰剂单独可以破坏情感和（神经）认知反应对错误的耦合。虽然其行为相关性仍有待证明，更多的关注应该放在行动监测和认知控制过程中的作用。
Alcohol intoxication can dampen negative affective reactions to stressors. Recently, it has been proposed that these acute anxiolytic effects of alcohol may extend to dampening of negative affective reactions to error commission during cognitive control tasks. Nonetheless, empirical verification of this claim is lacking. Test the acute effect of alcohol on negative affective reactions to errors during an effort-demanding cognitive control task. Healthy, young adult social drinkers (N=96 [49 women], 21-36 years old) were randomly assigned to consume alcohol (0.80 g/kg; n = 33 [15 female]), active placebo (0.04 g/kg; n = 33 [18 women]), or a non-alcoholic control beverage (n = 30 [16 women]) before completing the Eriksen flanker task. Corrugator supercilii (Corr) activation, a psychophysiological index of negative affect, was tracked across the task. Two neurophysiological reactions to errors, the error-related negativity (ERN) and the error positivity (Pe), were also measured. Erroneous actions increased Corr activation in the control and (to a lesser extent) placebo groups, but not in the alcohol group. Error-induced Corr activation was coupled to ERN and Pe in the control, but not in the alcohol and placebo groups. Error-induced Corr activation was not coupled to post-error performance adjustments in any group. The ability of alcohol to dampen error-related negative affect was verified. It was also shown that placebo alone can disrupt coupling of affective and (neuro)cognitive reactions to errors. Although its behavioral relevance remains to be demonstrated, more attention should be paid to the role of affect in action monitoring and cognitive control processes.
