本文以无意识理论为主要线索，结合乔姆斯基提出的“语言获得装置”，着重对儿童语言的获得与发展的内部机制问题进行了探索，认为这个内部机制是大脑基本结构“语言获得装置”（ＬＡＤ）与儿童出生后经过“锻炼”而内化了的、对语言的生成发展有直接作用的集体无意识相融合的产物。 Based on the theory of unconsciousness and the “language acquisition device” proposed by Chomsky, this dissertation focuses on the exploration of the internal mechanism of the acquisition and development of children’s language. It considers this internal mechanism as the “language acquisition device” (LAD) is a product of the collective unconsciousness that has a direct effect on the formation and development of language after the child has been “exercised” after birth.
