This study investigated error-monitoring deficits in female college students with binge drinking (BD) using event-related potentials (ERPs) and the modified Flanker task.
Participants were categorized into BD (n=25) and non-BD (n=25) groups based on the scores of the Korean-version of the Alcohol Use Disorder Identification Test (AUDIT-K) and the Alcohol Use Questionnaire (AUQ). The modified Flanker task, consisting of congruent (target and flanker stimuli are the same) and incongruent (target and flanker stimuli are different) conditions, was used to evaluate error-monitoring abilities.
The BD group exhibited significantly shorter response times and more error rates on the Flanker task, as well as reduced error-related negativity (ERN) amplitudes compared with the non-BD group. Additionally, ERN amplitudes measured at FCz and Cz were significantly correlated with scores on the AUDIT-K and AUQ in the whole participants. The BD and non-BD groups did not show any significant differences in error positivity amplitudes.
The present results indicate that college students with BD have deficits in error-monitoring, and that reduced ERN amplitudes may serve as a biological marker or risk factor of alcohol use disorder.
本研究采用事件相关电位（ERP）和改良的侧翼任务，调查了患有暴饮（BD）的女大学生的错误监测缺陷。
根据韩国版酒精使用障碍识别测试（AUDIT-K）和酒精使用问卷（AUQ）的得分，将参与者分为BD组（n = 25）和非BD组（n = 25）。改良的侧翼任务由一致（目标和侧翼刺激相同）和不一致（目标和侧翼刺激不同）条件组成，用于评估错误监测能力。
与非BD组相比，BD组在侧翼任务上的反应时间明显更短，错误率更高，且错误相关负波（ERN）振幅降低。此外，在整个参与者中，在FCz和Cz处测量的ERN振幅与AUDIT-K和AUQ的得分显著相关。BD组和非BD组在错误正波振幅上没有显示出任何显著差异。
目前的结果表明，患有BD的大学生在错误监测方面存在缺陷，ERN振幅降低可能是酒精使用障碍的生物学标志物或风险因素。
