心理学家做过一个简单实验,让人们把六根火柴摆出一个含有四个三角形的东西来,很多人感到难办,甚至认为不可能。原因是人们对待这类问题通常习惯于在一个平面上摆它,可问题并没有限定四个三角形必须在一个平面上。如有人给他们一个提示,可以竖起来,在立体空间来摆摆看,那么他们中大部分人都会很快用六根火柴摆出四个三角形(三个侧面三角形和一个底部三角形)。 Psychologists have done a simple experiment, letting people put six matches in a triangle with four things, many people find it difficult or even impossible. The reason is that people usually accustom to dealing with such problems in a plane, but the problem is not limited to the four triangles must be in a plane. If someone gives them a tip that can be erected and laid out in a solid space, most of them will quickly put four triangles (three side triangles and one bottom triangle) in six matches.
