How does the shape of a glass affect how much you drink? A scientist set out to examine just this, and the results are rather astounding.
Whatever the age of the subjects, they consistently poured more juice into short, wide tumbler|type glasses than into tall, slender glasses. But they perceived the opposite that they were pouring more into tall, slender glasses.
Psychologist Jean Piaget claimed that children overestimate the volume of vertical dimensions, but that as their brains mature, they develop the capacity to more accurately compare vertical and horizontal dimensions.
The results of this study do support Piagets idea to a certain extent in that the differential between the amount of juice adults poured into the two different glasses was less than the difference in what teenagers poured.
While adults poured about twenty percent more liquid into short, wide glasses, teenagers poured a whopping seventy|five percent more into short, wide glasses. Adults do seem to be better at comparing the volumes of different shapes, but they still overemphasize the volume of vertical shapes.
Even experienced bartenders, though to a lesser degree than the rest of us, still pour a little bit more into short, wide tumbler glasses than into taller, more slender glasses.
Who cares? If what youre pouring is medicine or if youre watching your weight, you might care. The teenagers in this study were at a camp where they were learning about portion control and dieting in order that they might lose weight. And yep the kids with the short, wide juice glasses were consuming significantly more calories than they realized.
水杯的形状是如何影响喝水量的呢?一位科学家计划调查一下，调查结果相当让人惊讶。
不管被试者年龄怎么样，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。但他们自己所感知的却刚好相反。他们觉得往高细杯里倒的更多。
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，但当他们大脑成熟时他们就会拥有准确区别垂直向和水平向容量的能力。
该研究结果在某种程度上支持了皮亚杰的看法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。
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。成人看着确实更擅长区别不同形状容器的容积，但他们仍然会高估垂直容器的容量。
即便是资深的调酒师，虽然比大家普通人强，但倒往宽的平底型杯里的酒也比倒往高细杯里的多。
哪个在乎呢?假如你倒的是药或你非常在乎你的体重，或许你会在乎。参加此次研究的青少年是在一个营地上，在那里他们掌握了节食减肥。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。
