The Optimization of Cognitive Factors Affecting the Semantic Network of L2 Mental Lexicon of College English Learners

本文将二语心理词汇看作词汇习得过程中信息加工的"终端产品",首先对大学英语学习者二语心理词汇语义网构建中的认知制约因素进行微观分析并提出优化设想——自主式外显词汇学习模式。然后以微变化研究方法,考察了在词汇认知因素优化环境下,大学生二语心理词汇语义知识的发展特征与个体差异。本研究同时关注词汇习得过程与习得结果,为二语心理词汇组织结构的研究提供了新视角。

Viewing L2 mental lexicon as the end-product of information processing in vocabulary acquisition, this paper analyzes the cognitive factors affecting the semantic network of the L2 mental lexicon and proposes an autonomous explicit vocabulary learning model as a means to optimize these cognitive factors. A microgenetic analysis is conducted on the development of college English learners＇ L2 mental lexicon and its individual differences in the optimized environment. With attention to both the process and product of vocabulary learning, the study offers a new perspective on the study of the nature of L2 mental lexicon.
