不同水平中国英语学习者心理词库组织及发展的实证研究

An empirical study on the organization and development of mental lexicon of Chinese EFL learners at different levels

本文旨在通过实证的方式探讨不同水平中国英语学习者心理词库组织特点和发展特征。研究发现:低水平组二语心理词库以非语义表征组织;纵聚合表征强于横组合表征。中高级水平组二语心理词库呈现非语义向语义表征迁移的趋势;横、纵组合同时发展,纵聚合表征发展快于横组合表征增长速度,但在二语水平达到一定高度后,横组合有向纵聚合迁移的趋势。不同水平组语义表征的各个子项反应发展呈现出共时非均衡的态势,主要表现在修饰、同义和上下义表征的发展速度具有明显优势。

This paper aims to explore the organizational characteristics and developmental trends of Chi- nese EFL learners＇ mental lexicon. Some major findings are as follows. First, the mental lexicon of low -level group is non -semantically related; syntagmatic relations appear stronger than paradigmatic ones. Second, in medium - and high -level groups, the non -semantic characterization would shift to semantic one; syntagmatic and paradigmatic relations may develop at the same time, but paradigmatic relations seem to develop faster than syntagmatie ones. After second language proficiency reaches a cer- tain degree, syntagmatic relations might transfer to paradigmatic ones. Third, the developmental se- quence of semantic representation＇ s sub - items are asynchronic and uneven, as the decorative charac- terization, synonymous characterization and hyponymic representation have obvious advantages in grow- ing pace.
