语言与智慧密切相关,智力落后儿童的最主要的特点是,语言障碍。佳佳的发展属于中上,他:两个月:会发音,无意义。四个月,咿呀作语,偶然发出 ba ba Ga Ga 音,如对他作声,他会用细小喉音回答,表现出语言的一来一回性质。七个月:模仿父亲发出的 ma ma、na na 音,但无意义,有时还发出一些难以理解的拼音。 Language and wisdom are closely related to the most prominent feature of children with mental retardation, language barriers. All good development belongs to the middle, he: two months: will pronounce, meaningless. For four months, Baba Ga Ba sounds occasionally, and as he makes a sound, he will answer in small tweezers, showing the nature of language in and of one time. Seven months: imitating ma ma, na na sounds from my father, but meaningless, sometimes giving some incomprehensible pinyin.
