How does the shape of a glass affect how much you drink?
水杯的形状是怎样影响喝水量的呢？
Ascientist set out to examine just this, and the results are ratherastounding.
一位科学家打算调查一下，调查结果相当令人惊讶。
Whatever the age of the subjects, they consistently pouredmore juice into short, wide tumbler-type glasses than into tall,slender glasses.
但是他们自己所感知的却刚好相反。他们认为往高细杯里倒的更多。
But they perceived the opposite that they werepouring more into tall, slender glasses.
不管被试者年龄如何，他们都一致地往宽的平底型杯里倒的橘汁比往高细杯里倒的多。
Psychologist Jean Piaget claimed that children overestimate the volume of vertical dimensions,
心理学家珍皮亚杰声称孩子们会高估垂直方向的容器容量，
but that as their brains mature, they develop the capacity to more accurately compare vertical andhorizontal dimensions.
但是当他们大脑成熟时他们就会具备准确区分垂直向和水平向容量的能力。
The results of this study do support Piaget's idea to a certain extent in that the differential betweenthe amount of juice adults poured into the two different glasses was less than the difference inwhat teenagers poured.
该研究结果在某种程度上支持了皮亚杰的观点—成人倒往不同杯子里相差的橘汁少于青少年倒往不同杯子里相差的橘汁。
While adults poured about twenty percent more liquid into short, wide glasses, teenagers poured a whopping seventy-five percent more into short, wide glasses.
成人往矮宽杯里多倒20%的橘汁时青少年却要多倒高达70%的橘汁。
Adults do seem to be better atcomparing the volumes of different shapes, but they still overemphasize the volume of verticalshapes.
成人看起来确实更善于区分不同形状容器的容积，但他们仍然会高估垂直容器的容量。
Even experienced bartenders, though to a lesser degree than the rest of us, still pour a little bitmore into short, wide tumbler glasses than into taller, more slender glasses.
即使是经验丰富的调酒师，虽然比我们普通人强，但倒往宽的平底型杯里的酒也比倒往高细杯里的多。
Who cares? If what you're pouring is medicine or if you're watching your weight, you might care.
谁在乎呢？如果你倒的是药或你很在意你的体重，也许你会在乎。
The teenagers in this study were at a camp where they were learning about portion control anddieting in order that they might lose weight.
参加此次研究的青少年是在一个营地上，在那里他们学会了节食减肥。
And yep the kids with the short, wide juice glasseswere consuming significantly more calories than they realized.
而且拿着矮宽橘汁杯的孩子消耗的热量比他们意识到的多。
