Abstract：
Alcohol has been linked to both positive (e.g., sociability) and negative (e.g., aggression) social outcomes, and researchers have proposed that alcohol-induced changes in emotion recognition may partially explain these effects. Here, we systematically review alcohol administration studies to clarify the acute effects of alcohol on emotion recognition. We also investigate various moderator variables (i.e., sex, study quality, study design, alcohol dosage, emotion recognition task and outcome measure). PsycINFO, PubMed and Google Scholar were searched following a pre-registered PROSPERO protocol (CRD42021225392) and PRISMA methodology. Analyses focused on differences in emotion recognition between participants consuming alcoholic and/or non-alcoholic (i.e., placebo or no-alcohol control) beverages. Nineteen unique samples (N = 1271 participants) were derived from 17 articles (two articles included two studies, each conducted on a unique sample). Data were extracted for sample characteristics, alcohol administration methods and emotion recognition tasks and outcomes. All studies compared an alcoholic beverage to a placebo beverage and used tasks that asked participants to identify emotions from images or videos of facial expressions. Otherwise, methodologies varied substantially across studies, including the alcohol dosage(s) tested, the specific emotion recognition task(s) used and the outcome variable(s) assessed. No consistent effects of alcohol on emotion recognition emerged for any emotion. None of the moderator variables affected the findings, except for some indication that alcohol may affect males\' emotion recognition abilities more so than females. Alcohol does not appear to consistently affect positive or negative emotion recognition of facial expressions, at least with the tasks currently used in the field.
摘要：
酒精与两者都呈阳性(例如，社交能力)和消极(例如，侵略)社会结果，研究人员提出，酒精引起的情绪识别变化可能部分解释了这些影响。这里,我们系统地回顾了酒精管理研究，以阐明酒精对情绪识别的急性影响。我们还研究了各种主持人变量(即，性别,学习质量,研究设计，酒精用量,情绪识别任务和结果测量)。PsycINFO,根据预先注册的PROSPERO协议（CRD42021225392）和PRISMA方法搜索PubMed和GoogleScholar。分析的重点是消费酒精和/或非酒精的参与者之间的情绪识别差异(即，安慰剂或无酒精控制)饮料。19个独特样本(N=1271名参与者)来自17篇文章(两篇文章包括两项研究，每个都在一个独特的样本上进行)。提取样本特征的数据，酒精管理方法和情绪识别任务和结果。所有研究都将酒精饮料与安慰剂饮料进行了比较，并使用了要求参与者从面部表情的图像或视频中识别情绪的任务。否则,不同的研究方法差异很大，包括测试的酒精剂量，使用的特定情绪识别任务和评估的结果变量。对于任何情绪，酒精对情绪识别没有一致的影响。主持人变量都不会影响调查结果，除了一些迹象表明酒精可能比女性更影响男性的情绪识别能力。酒精似乎不会持续影响面部表情的正面或负面情绪识别，至少与当前在该领域使用的任务有关。
