摘要
本研究对比了两代(2005/2023)英语专业学生词汇联想网络的语义组织及整体网络变化.结果显示:1)两代学习者英语心理词库均以语义组织为主,高低水平者对词汇搭配和层级知识的侧重不同,现阶段学生的屈折派生知识显著提高;2)两代学习者的联想网络结构均符合"小世界"特性,网络疏密度随语言水平而增大至稳定,稳定性随小世界程度的加深而减弱.本研究为英语词汇学习提供了历时发展图景,对词汇学习诊断有启示.
Abstract
This study adopts word association tests to investigate diachronic changes in organizational patterns and network structures of Chinese EFL learners'word association networks during two decades.Results show that:1)Chinese EFL learners'word association networks are dominated by semantic relations,with low and high proficiency participants exhibiting different developmental trends in terms of collocational and hierarchical knowledge;learners in current stage perform a dramatic increase of morphological relations in non-semantic responses;2)Chinese EFL learners'word association networks possess the"small-world"property,with sparsity increasing as L2 proficiency grows and stability declining as"small-worldness"increases.This study provides a diachronic depiction of vocabulary learning and insights for vocabulary assessment.
