酒精近视（AM）已成为酒精对情绪体验影响的最广泛研究理论之一。鉴于这一理论的流行，值得注意的是，AM的核心原则尚未得到验证，即酒精会造成对当前时刻的短视关注，限制了当前被来自先前经验的情绪渗透的程度。我们测试了酒精对情绪波动的影响，应用情绪评估和统计分析的进展来测试AM的这一方面，而不引起参与者对自己情绪体验的注意。我们使用自相关性来测量情绪波动，这是一种从时间序列分析中借用的统计数据，用于测量连续观察结果之间的相关性。高情绪自相关被称为情绪惯性，与消极情绪结果有关。社交饮酒者（N = 720）在36分钟的小组形成任务中，以3人为一组，饮用酒精、安慰剂或对照饮料。我们使用Duchenne微笑对影响进行索引，根据面部动作编码系统（P. Ekman，W. V.弗里森，& J. C. Hager，2002年）。自相关的杜兴微笑出现作为最一致的预测自我报告的情绪和社会联系相比，杜兴微笑的平均值，标准差和线性趋势。酒精降低了情感自相关，自相关介导了酒精和自我报告的情绪和社会结果之间的联系。研究结果表明，酒精增强了自由享受当下的能力，不受过去经验的束缚，并强调了情感动力学在研究精神病理学情感相关因素中的重要性。
Alcohol myopia (AM) has emerged as one of the most widely researched theories of alcohol's effects on emotional experience. Given this theory's popularity, it is notable that a central tenet of AM has not been tested namely, that alcohol creates a myopic focus on the present moment, limiting the extent to which the present is permeated by emotions derived from prior experience. We tested the impact of alcohol on moment-to-moment fluctuations in affect, applying advances in emotion assessment and statistical analysis to test this aspect of AM without drawing the attention of participants to their own emotional experiences. We measured emotional fluctuations using autocorrelation, a statistic borrowed from time-series analysis measuring the correlation between successive observations in time. High emotion autocorrelation is termed emotional inertia and is linked to negative mood outcomes. Social drinkers (N = 720) consumed alcohol, placebo, or control beverages in groups of 3 over a 36-min group formation task. We indexed affect using the Duchenne smile, recorded continuously during the interaction (34.9 million video frames) according to the Facial Action Coding System (P. Ekman, W. V. Friesen, & J. C. Hager, 2002). Autocorrelation of Duchenne smiling emerged as the most consistent predictor of self-reported mood and social bonding when compared with Duchenne smiling mean, standard deviation, and linear trend. Alcohol reduced affective autocorrelation, and autocorrelation mediated the link between alcohol and self-reported mood and social outcomes. Findings suggest that alcohol enhances the ability to freely enjoy the present moment untethered by past experience and highlight the importance of emotion dynamics in research examining affective correlates of psychopathology.
