背景研究表明，人们在估计自己提供的酒量方面做得很差。玻璃杯的形状、冰的存在和酒精消费量可能会影响人们倒酒的数量和估计他们倒了多少酒。这些研究的目的是检验这些因素是否会在实验室和现实环境中影响倒酒行为。方法通过4项研究、1项实验室研究和3项公共活动期间进行的研究，我们测试了玻璃杯形状(直边高脚杯和平底杯)的影响，并使用冰的替代品(威士忌石)测试了冰对倾倒和估计自定义典型饮料的影响。我们还评估了饮酒量和倒酒准确度之间的关系。结果总的来说，参与者总是高估了他们典型的酒精摄入量，当倒入空杯子时，他们会倒入超过1英国单位的酒。研究结果表明，玻璃杯形状或冰替代品对酒精单位估计或典型服务量没有可信的影响。然而，尽管酒精消耗量与准确度无关，但在倒入一单位英国酒时，冰替代品的存在提高了准确度。结论鉴于参与者高估了他们典型的酒精饮料中的酒精含量，自我报告酒精消耗量的方法可能夸大了个人的酒精消耗量。此外，在倒入标准份量(英国单位)的酒精时，冰的存在可能会提高准确度。因此，如果考虑到冰的存在，自我报告措施可能会得到改进。
BackgroundResearch suggests that people are poor at estimating the amount of alcohol they have served themselves. Glass shape, the presence of ice, and alcohol consumption may influence the amount of alcohol people pour and estimate they have poured. The aim of these studies was to examine whether these factors would affect pouring behavior, in the laboratory and in real‐world environments.MethodsAcross 4 studies, 1 laboratory study and 3 conducted during public engagement events, we tested the effect of glass shape (straight sided highball and tumbler glasses) and, using an ice substitute (whiskey stones), the effect of ice on pouring and estimating a self‐defined typical drink. We also assessed the association between alcohol consumption and pouring accuracy.ResultsOverall, participants consistently overestimated their typical serving of alcohol, and poured more than 1 U.K. unit when pouring into an empty glass. Findings demonstrate no credible effect of glass shape or ice substitute on alcohol unit estimation or the amount of a typical serving. However, while alcohol consumption was not related to accuracy, the presence of an ice substitute improved accuracy when pouring a single U.K. unit.ConclusionsGiven that participants overestimated the amount of alcohol in their typical alcoholic drink, self‐report measures of alcohol consumption may be overstating the amount of alcohol individuals consume. Additionally, the presence of ice may improve accuracy when pouring standard servings (U.K. units) of alcohol. Therefore, self‐report measures may be improved if the presence of ice is considered.
