An experiment was conducted in which 66 male subjects were given access to alcohol (20% vol.) and fruit juice to be mixed and tasted ad lib. A factorial design included social vs. solitary drinking conditions, laboratory vs. informal setting, and variable exposure to music. The amount of ethanol consumed (g/kg body weight) was used as an unobtrusive measure of preferred intake. The reciprocal relationship between mood and consumption was analyzed by LISREL. While euphoria has usually been perceived as a consequence of drinking, the only plausible fit to a LISREL model was obtained by assuming that the disposition to drink would be increased by positive mood changes occurring during the drinking session. An analogy between social drinking and adjunctive behaviour was supported, as alcohol consumption was directly affected by time-dependent environmental factors such as company and music. Since the presence of company also stimulated positive mood and alleviated boredom, consumption was precipitated by company indirectly as well as directly. These results emphasize the importance of direct as well as indirect environmental influences on spontaneous alcohol intake during social drinking.
进行了一项实验，让66名男性受试者自由取用酒精（体积分数20%）和果汁进行混合并随意品尝。析因设计包括社交饮酒与独自饮酒条件、实验室环境与非正式环境，以及不同程度的音乐暴露。摄入的乙醇量（克/千克体重）被用作偏好摄入量的一种客观测量指标。通过线性结构关系模型（LISREL）分析了情绪与饮酒量之间的相互关系。虽然欣快感通常被视为饮酒的结果，但通过假设在饮酒过程中出现的积极情绪变化会增加饮酒倾向，才得到了唯一符合线性结构关系模型的结果。社交饮酒与辅助行为之间的类比得到了支持，因为饮酒量直接受到诸如同伴和音乐等随时间变化的环境因素的影响。由于同伴的存在也会激发积极情绪并减轻无聊感，饮酒量会因同伴的直接和间接影响而增加。这些结果强调了在社交饮酒过程中，直接和间接环境因素对自发酒精摄入量的重要影响。
