Abstract
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 (N = 60; Mage = 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: b = -0.174, t = -2.36, p = .022; negative affect, b = 0.4319, t = 2.37, p = .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：情绪测量是捕捉急性酒精强化的核心，从而为酒精使用障碍病因模型提供信息。然而，我们对酒精如何影响不同反应模式的情绪的理解仍然不完整。本研究利用社会酒精管理范式来评估饮酒相关情绪，旨在阐明醉酒对自我报告和行为表达情绪的影响。方法：参与者(N = 60；法师= 22.5；男性50%;55%的白人)参加了两个平衡的实验室实验，其中一个实验给他们提供酒精饮料（目标血液酒精含量为0.08%），另一个实验给他们提供不含酒精的对照饮料。在这两种情况下，参与者都被准确地告知饮料的成分，并被分成三人一组饮用研究饮料，同时他们的行为被录像。通过自我报告和面部肌肉运动的连续编码来评估情绪。结果：不同饮料条件下，自我报告情绪与行为表达情绪的关系存在显著差异：积极情绪：b = -0.174, t = -2.36, p = 0.022；负性影响，b = 0.4319, t = 2.37, p = 0.021。具体来说，清醒而非醉酒的参与者的自我报告和行为表现趋于一致。此外，在控制自我报告的积极情绪和消极情绪的模型中，酒精对积极面部表情的影响仍然很显著，酒精对杜兴微笑的影响比自我报告所捕获的效果高出20%，这表明酒精对积极情绪行为指标的独特影响。结论：研究结果强调了急性中毒对情绪测量的趋同和分歧的影响，从而使我们了解捕捉最接近饮酒的情绪的措施，从而最直接地加强酒精消费。（PsycInfo Database Record (c) 2025 APA，版权所有）。
