OBJECTIVE
Emotion measurement is central to capturing acute alcohol reinforcement and so to informing models of alcohol use disorder etiology. Yet our understanding of how alcohol impacts emotion as assessed across diverse response modalities remains incomplete. The present study leverages a social alcohol-administration paradigm to assess drinking-related emotions, aiming to elucidate impacts of intoxication on self-reported versus behaviorally expressed emotion.
METHOD
Participants ( = 60; = 22.5; 50% male; 55% White) attended two counterbalanced laboratory sessions, on one of which they were administered an alcoholic beverage (target blood alcohol content .08%) and on the other a nonalcoholic control beverage. Participants in both conditions were accurately informed of beverage contents and consumed study beverages in assigned groups of three while their behavior was videotaped. Emotion was assessed via self-report as well as continuous coding of facial muscle movements.
RESULTS
The relationship between self-reported and behaviorally expressed emotion diverged significantly across beverage conditions: positive affect: = -0.174, = -2.36, = .022; negative affect, = 0.4319, = 2.37, = .021. Specifically, self-reports and behavioral displays converged among sober but not intoxicated participants. Further, alcohol's effects on positive facial displays remained significant in models controlling for self-reported positive and negative emotion, with alcohol enhancing Duchenne smiles 20% beyond effects captured via self-reports, pointing to unique effects of alcohol on behavioral indicators of positive emotion.
CONCLUSIONS
Findings highlight effects of acute intoxication on the convergence and divergence of emotion measures, thus informing our understanding of measures for capturing emotions that are most proximal to drinking and thus most immediately reinforcing of alcohol consumption.

目的
情绪测量对于捕捉急性酒精强化作用至关重要，因此对于了解酒精使用障碍的病因模型也很重要。然而，我们对于酒精如何通过多种反应方式影响情绪的理解仍不完整。本研究利用一种社交酒精给药范式来评估与饮酒相关的情绪，旨在阐明醉酒对自我报告的情绪与行为表达的情绪的影响。
方法
参与者（(n = 60)；(M = 22.5)；50%为男性；55%为白人）参加了两个平衡的实验室环节，其中一个环节他们饮用酒精饮料（目标血液酒精含量为0.08%），另一个环节饮用非酒精对照饮料。两种情况下的参与者都准确被告知饮料内容，并在三人一组的指定小组中饮用研究饮料，同时对他们的行为进行录像。通过自我报告以及对面部肌肉运动的连续编码来评估情绪。
结果
在不同饮料条件下，自我报告的情绪与行为表达的情绪之间的关系存在显著差异：积极情绪：(r = -0.174)，(t = -2.36)，(p = .022)；消极情绪，(r = 0.4319)，(t = 2.37)，(p = .021)。具体而言，清醒参与者的自我报告和行为表现趋于一致，但醉酒参与者并非如此。此外，在控制了自我报告的积极和消极情绪的模型中，酒精对积极面部表情的影响仍然显著，酒精增强杜兴微笑的程度比通过自我报告捕捉到的影响高出20%，这表明酒精对积极情绪行为指标有独特影响。
结论
研究结果突出了急性醉酒对情绪测量的趋同和差异的影响，从而增进了我们对捕捉与饮酒最接近、因此对饮酒最直接起到强化作用的情绪测量方法的理解。（PsycInfo数据库记录（c）2025美国心理学会，保留所有权利）
