The aim of this study was to assess the impact of cues that signal the alcoholic strength of a beverage on drinking rate in young social drinkers.
In Experiment 1, two groups of young social drinkers (n=20 per group) consumed a lager-based drink containing either 3% or 7% alcohol-by-volume. The pattern of drinking behaviour was observed, and drinking time was recorded. Self-reported mood was measured across the session, and participants also provided ratings of the drinks' sensory and hedonic properties. Experiment 2 replicated Experiment 1, but used a within-subjects design (n=12).
In both experiments, participants took significantly longer to consume the 7% drink compared with the 3% drink, and the total inter-sip interval was longer for the 7% drink. These effects were most closely related to the participants' changing estimates of alcohol strength across the test session, alongside concomitant changes in various aspects of self-reported mood. Sensory and hedonic evaluations of the drinks did not affect drinking behaviour in either experiment.
The findings suggest that the consumption rate of an alcoholic beverage can be modulated by its alcohol content, and that the perceived pharmacological effect of the alcohol serves as an effective signal to alter drinking behaviour.
本研究旨在评估提示饮料酒精强度的线索对年轻社交饮酒者饮酒速度的影响。
在实验1中，两组年轻社交饮酒者（每组n = 20）饮用了两种基于贮藏啤酒的饮料，其酒精体积分数分别为3%和7%。观察饮酒行为模式，并记录饮酒时间。在整个实验过程中测量自我报告的情绪，参与者还对饮料的感官和享乐特性进行评分。实验2重复了实验1，但采用了被试内设计（n = 12）。
在两个实验中，与3%的饮料相比，参与者饮用7%的饮料花费的时间明显更长，并且7%饮料的总啜饮间隔时间更长。这些效应与参与者在测试过程中对酒精强度变化的估计密切相关，同时自我报告情绪的各个方面也随之发生变化。在两个实验中，对饮料的感官和享乐评价均未影响饮酒行为。
研究结果表明，酒精饮料的消费速度可受其酒精含量调节，并且酒精的感知药理作用是改变饮酒行为的有效信号。
