二语词汇习得研究综述

An Overview of L2 Vocabulary Acquisition

三十多年来,二语词汇习得研究成为二语习得研究中最热点的下属领域之一。二语词汇习得研究无论在理论性研究还是实证性研究方面都有新的发展,理论性研究的成果是三大心理模型的建立,实证性研究致力于在不同的学习条件下二语词汇是怎样被习得的以及什么因素会影响二语词汇习得的效度和方式。此外,认知语言学的兴起为二语词汇习得带来了新的发展趋势。

In the past thirty years, L2 vocabulary acquisition has become one of the hottest areas of SLA. This paper reviews three psycholinguistic models of lexical representation and development in a second language that intends to explore the mental representation and processing of L2 vocabulary acquisition from different perspectives. The three psycholinguistic models are respectively： Kroll ＆ Stewart＇s（1994） Revised Hierarchical Model, De Bot et al＇s （1997） Lexical processing model and Jiang＇s （2000） L2 lexical representation and development model. The rich empirical studies have been devoted to understanding how L2 vocabulary can be acquired under different conditions and what factors influence the effectiveness and patterns of L2 vocabulary acquisition. Besides,many researchers have applied the theory of cognitive linguistics to vocabulary teaching and learning and the results are satisfying. Therefore, the development of cognitive linguistics brings about a new and promising trend to the study of L2 vocabulary acquisition.
