美国有位心理学家曾经做过这样一个试验,他将他的学生分成三组,对第一组表示信任并予以赞美与鼓励;对第二组采取不管不问放任自流的态度;对第三组则不断给予批评。试验表明,被经常鼓励的第一组进步最快,总是挨批的第三组有些进步,而被漠视的第二组则在原地踏步。 A psychiatrist in the United States has conducted such an experiment in which he divided his students into three groups, expressing trust in the first group and praising and encouraging them; adopting a second group in a self-reliant attitude; Groups are constantly criticized. Experiments show that the first group, which is often encouraged, has made the strongest progress and the third group, which has always been criticized, has made some progress while the second group, which has been disregarded, has been making progress.
