摘要
通过对有关大脑功能侧化及语言习得时效关系诸多假说的历史回顾与批评 ,有机地结合语言学与脑科学研究的新发现 ,本文旨在以语言比较研究为发入点 ,宏观地阐述 :1 不同语言体系言语能力掌握过程中神经与生理机制的独特性。 2 语言习得 ,特别是第二语言习得的最佳年龄争议及其社会制约因素的存在 ,对脑动力定型个性化与习得临界理论社会化的综合分析同时也是调和传统语言教学方法与脑科学等前沿学科间研究对象矛盾的尝试之一例。
With a brief literature review of the hypotheses concerning the functional lateralization and the age factors of language acquisition, this paper, from a macro aspect of neurolinguistic study, elaborates on: 1.the unique quality of the neuro-and physical mechanism of the language learners in the acquisition of different verbal systems; 2.the controversial issue regarding the optimal age for second language learning as well as the influence of social factors. Meanwhile, through new discoveries in the fields of linguistics, neurology and physiology,the paper also serves as an attempt to reconcile the contradiction between traditional language teaching methods and brain science with regard to their objects of research.
