母语与外语"知识-认知双元结构"在FLT中的理论解析

本文从心理语言学的角度,就成年人学习和习得外语,并针对诺姆·乔姆斯基的"语言习得装置"(language acquisition device,即LAD)理论中的不足部分,提出了"语言种子与语言习得树"(language seed and language acquisition tree,即LS&LAT)、"外语习得中母语与外语的认知与知识双元结构理论"和"成年人习得外语在心智认知活动上存在有三种认知结构系统的观点"等观点,并就此进行了解析.文章指出,以上学术观点是就成年人学习和习得外语在理论上对乔姆斯基理论的补充和深化.

Theoretical Analysis on Cognition-Knowledge Bilingual Double Structures between Mother Language and Foreign language in Foreign Language Teaching

From psycholinguistic point of view,and in the light of the traits of adults' foreign language learning and acquisition(FLL&FLA),and in view of the insufficiency of Noam Chomsky's theory of Language Acquisition Device(LAD),this paper puts forward Language Seed and Language Acquisition Tree(LS&LAT),Cognition-Knowledge Bilingual Double Structures between mother language and foreign language in FLA,and three systems of cognitive psycho-structures existing in adults' mental cognitive activities in the process of FLA,and then makes explanation and analysis on these three proposed theories.The paper points out that the above theories intend to supplement and deepen Chomsky's LAD theory mainly on adults' FLL&FLA theoretically.
