环境语言输入与儿童语言习得相关性计量研究

Qualitative Research on the Correlation of Language Input and Child's Language Acquisition

针对乔姆斯基儿童语言能力来自先天遗传的假设,本文通过个案追踪方式采集语料,建立儿童语言出现前后阶段(10—30个月)成人与儿童话语语料库,对转写后的成人和儿童话语词句进行统计分析与抽样比对,发现成人话语输入对儿童语言习得影响作用明显,输入频率高低与儿童习得快慢呈正相关。后天语言环境通过高频率、适合交谈情景和儿童需求的、略前于儿童语言发展水平的刺激,与儿童的认知能力相互作用、相互促进,共同推动儿童语言的发展。

This paper, based on a corpus of adult＇s and child＇s utterance （10-30 months）, provides a statistical analysis that reveals the correlation between language input and output. It aims at questioning UG theory raised by Noam Chomsky. It concludes that adult＇s language input affects child language acquisition obviously. There is positive correlation between frequency of input and child language acquisition. Therefore language environment plays an important role in child language acquisition. Language environment and child＇ s cognitive ability mutually promote child＇s language development by stimulation of high frequency, suitable for communicative context, and slightly ahead of the level of child＇s language development.
