三四岁的幼儿有一个明显的心理特征:始终不自量地以他自己为中心;出于对成人的尊敬而产生的服从也是不自觉的。换言之,三四岁的幼儿还不能很融洽地同成人合作。因而,在这个时期,幼儿对成人的话有时能服从,但经常出现的是“反抗”。于是,成人时常抱怨说:“这孩子太任性!” The three- and four-year-olds have a clear psychological trait: they are always self-centered; obedience to respect for adults is unconscious. In other words, three or four-year-old children still can not cooperate well with adults. Thus, during this period, young children can sometimes obey adults, but what they often do is “resist.” As a result, adults often complain: “This kid is too headstrong!”
