一岁左右的幼儿开始认识到别人和自己的区别,有了自我的感觉和认识。但他们仍然对别人的感情状态作出灵敏的反应,好像别人的感情就是自己的一样,并且认为,能使自己高兴和满足的事情也会使别人高兴和满足,因而,他会用自己喜欢的东西去试图使别人也高兴和喜欢。到两岁多,孩子开始感觉到别人的痛苦不像是、至少不完全是自己的痛苦,并能意识到能使自己高兴的东西不一定能使别人也高兴。 One-year-old children began to recognize the difference between others and themselves, with their own feelings and understanding. But they still respond sensitively to the emotional state of others as if others’ feelings are their own, and think that things that make themselves happy and satisfied will make others happy and satisfied, so he will use their favorite things Go try to make others happy and like it too. By the age of two, children begin to feel that the pain of others is not, at least not wholly, their own pain, and aware that something that makes them happy does not necessarily make others happy too.
