The ability to accurately detect alcohol intoxication is an important skill for people who use these substances and for a variety of professions (e.g. policing, responsible service of alcohol). Previous studies have found that intoxicated people are generally poor at estimating their own intoxication (particularly at high blood alcohol concentration; BAC) and the relationship between perceived intoxication and BAC appears to flatten at higher BAC levels. Studies of observer ratings of other's intoxication have yielded mixed results. The aim of this study was to investigate both self- and observer-ratings of intoxication against BAC levels to determine whether we observe a similar flattening in intoxication for both self- and observer-rated intoxication.

你有多陶醉？调查与血液酒精浓度相关的自我和观察者中毒等级

准确检测酒精中毒的能力对于使用这些物质的人和各种职业（例如警务、负责任的酒精服务）来说是一项重要技能。先前的研究发现，醉酒的人通常难以估计自己的醉酒情况（尤其是在高血液酒精浓度；BAC 时），并且在 BAC 水平较高时，感知到的醉酒与 BAC 之间的关系似乎趋于平缓。观察者对他人醉酒评分的研究产生了好坏参半的结果。本研究的目的是调查自我和观察者对 BAC 水平的中毒评分，以确定我们是否观察到自我和观察者中毒的类似的中毒变平。
