心理定式这种心理现象最早是由德国心理学家缪勒发现的。他提出,在人的意识中出现过的观念,有一种在意识中有再重复出现的趋势。他曾经通过大量的实验来证明心理定式的存在。比如,让一个人连续10次到15次手里拿两个重量完全相等的球,然后再让他拿两个重量有差别的球,他也会感知为完全相等。有一位心理学家说过:“只会使用锤子的人,总是把一切问题都看成钉子。”就像卓别林主演的《摩登时代》里那 Psychological stereotypes of this psychological phenomenon was first discovered by the German psychologist Muller. He proposed that the concepts that have appeared in human consciousness have a tendency of recurring in consciousness. He has been through a large number of experiments to prove the existence of mental formula. For example, let a person 10 times to 15 times in his hand to take two exactly the same weight of the ball, and then let him take two different weight ball, he would also be perceived as exactly the same. A psychologist once said: “Only people who use a hammer always think of everything as a nail.” Like Chaplin starred in “Modern Times”
