在以优势反应倾向和不相容的替代反应之间的冲突为特征的环境中，酒精中毒经常导致失调的行为。最近的研究已经确定了前执行注意系统的两个组成部分，当反应冲突存在时，它们对适应行为至关重要。收集评价性和调节性认知控制的事件相关电位（ERP）测量值，以确定执行注意力受损是否是醉酒时观察到的行为缺陷的原因。相对于清醒的对照组，醉酒的参与者在不一致的颜色命名试验中表现出任务表现缺陷。酒精不影响P3幅度/潜伏期，这表明刺激评价的时间和完整性保持不变。相反，酒精确实减少了ERP的额叶成分，这些成分是评估和调节认知控制过程的指标。
Alcohol intoxication often leads to dysregulated behavior in contexts characterized by conflict between prepotent response tendencies and incompatible alternative responses. Recent research has identified 2 components of an anterior executive attention system that are essential for adaptive behavior when response conflict exists. Event-related potential (ERP) measures of evaluative and regulative cognitive control were collected to determine if impaired executive attention was responsible for observed behavior deficits when intoxicated. Intoxicated participants displayed task performance deficits on incongruent color-naming trials relative to sober controls. Alcohol did not affect P3 magnitude/latency, indicating that timing and integrity of stimulus evaluation remained intact. In contrast, alcohol did reduce frontal components of ERP that index evaluative and regulative cognitive control processes.
