As the problems of mood measurements during alcohol consumption of alcoholic beverages do not necessarily evoke interpretable physiological responses, explicit reports may be contaminated by various cognitive biases or expectations. The present study examined whether emotional responses induced by the consumption of beverages containing low concentrations of alcohol can be measured using the Implicit Association Test (IAT). The IAT can detect the estimates of internal proximity between bipolar target concepts (e.g., cheerfulness and fatigue). Participants ( = 30) received three IAT sessions, followed by drinking a beverage containing 0% (control), 1%, or 3% alcohol by volume, and three IATs (at 0, 30, and 60 min after the time of consumption). We also recorded the explicit responses regarding the extent of drunkenness. The analyses of variance with alcohol concentration and time reveal dissociation between implicit and explicit measures. The IAT scores under the alcohol conditions reflect a more cheerful mood state relative to the baseline test. This effect of enhanced cheerfulness was not observed under the non-alcohol control condition. These results demonstrate that the impact of the consumption of low-alcohol beverages on mood can be measured using the IAT.
由于在饮用酒精饮料期间进行情绪测量的问题不一定会引发可解释的生理反应，明确的报告可能会受到各种认知偏差或期望的影响。本研究探讨了是否可以使用内隐联想测验（IAT）来测量饮用低浓度酒精饮料所引发的情绪反应。IAT能够检测双极目标概念（如愉悦和疲惫）之间的内部接近程度估计。参与者（n = 30）接受了三次IAT测试，然后饮用了按体积计含0%（对照）、1%或3%酒精的饮料，并在饮用后0、30和60分钟进行了三次IAT测试。我们还记录了关于醉酒程度的明确反应。对酒精浓度和时间的方差分析揭示了内隐和外显测量之间的分离。与基线测试相比，酒精条件下的IAT分数反映出更愉悦的情绪状态。在无酒精对照条件下未观察到这种愉悦增强的效果。这些结果表明，饮用低酒精饮料对情绪的影响可以通过IAT来测量。
