Most alcohol consumption takes place in social contexts, and the belief that alcohol enhances social interactions has been identified as among the more robust predictors of alcohol use disorder (AUD) development. Yet, we know little of how alcohol affects mental representations of others-what we share and do not share-nor the extent to which intoxication might impact the development of shared understanding (i.e., common ground) between interaction partners. Employing a randomized experimental design and objective linguistic outcome measures, we present two studies examining the impact of alcohol consumption on the development and use of common ground.
In Study 1, groups of strangers or friends were administered either alcohol (target Breath Alcohol Content = .08%) or a control beverage, following which they completed a task requiring them to develop a shared language to describe ambiguous images and then describe those images to either a knowledgeable or a naïve partner. The same procedures were completed in Study 2 using a within-subjects alcohol administration design and all-stranger groups.
Study 1 findings did not reach significance but suggested that alcohol may facilitate common ground development selectively among stranger groups. This effect emerged as significant in the context of the within-subjects design of Study 2, = -0.19, = .007, with participants demonstrating greater facility in establishing common ground during alcohol versus control sessions.
Results suggest that alcohol facilitates the development of shared linguistic understanding in novel social spaces, indicating common ground as one potential mechanism to consider in our broader examination of alcohol reinforcement and AUD etiology.

大多数饮酒行为发生在社交环境中，而认为酒精能增强社交互动的信念已被确定为酗酒障碍（AUD）发展的更有力预测因素之一。然而，我们对酒精如何影响他人的心理表征（我们共享和不共享的内容）以及醉酒在何种程度上可能影响互动伙伴之间共享理解（即共同基础）的发展知之甚少。本研究采用随机实验设计和客观语言结果测量，开展了两项研究，以检验饮酒对共同基础的发展和使用的影响。
在研究 1 中，陌生人或朋友组成的小组分别接受酒精（目标呼气酒精含量=0.08%）或对照饮料，然后完成一项需要他们开发共同语言来描述模糊图像的任务，然后将这些图像描述给有知识的或天真的伙伴。在研究 2 中采用了一个在组内进行的酒精管理设计和所有陌生人的小组，完成了相同的程序。
研究 1 的结果没有达到显著性，但表明酒精可能会选择性地促进陌生人组共同基础的发展。这一效应在研究 2 的组内设计中变得显著，r=-0.19，p=.007，参与者在酒精与对照期的会话中表现出建立共同基础的更大能力。
结果表明，酒精促进了在新的社交空间中共享语言理解的发展，表明共同基础是我们更广泛地研究酒精强化和 AUD 病因时需要考虑的一个潜在机制。（PsycInfo 数据库记录（c）2024 APA，保留所有权利）。
