国际三语习得研究前沿可视化分析

A Visualized Analysis of International Fronts of Third Language Acquisition Research

本文以2006—2018年间Web of Science数据库中的三语习得研究文献为数据来源,借助Cite Space软件对近年间的国际三语习得研究进行可视化分析,旨在了解该领域的研究趋势和前沿。研究发现:(1)高影响力文献主要包括构建三语迁移模型和介绍三语研究全貌;(2)前沿课题体现在三个维度上:语言学(三语句法–语篇界面研究)、认知(生成语法下的三语初始状态研究、迁移理论模型、普遍语法在三语习得中的可及性研究、认知理据、情感因素研究)和社会文化(社会文化理论下的任务模式研究);(3)重要学者主要探讨三语习得理论模型。

Based on studies with regard to third language(L3)acquisition in the Web of Science database from 2006 to 2018,this paper reports a visual analysis of international L3 acquisition research in recent years using CiteSpace,aiming at a better understanding of the research trends and frontiers in this field.The study has found that(1)high-influential studies in the international studies of L3 acquisition have focused on two aspects:the construction of theoretical models of L3 transfer and an introduction to the panorama of L3 acquisition research;(2)the research fronts of L3 acquisition have mainly focused on three dimensions:the linguistic dimension(L3 syntax-discourse interface),the cognitive dimension(the initial state of L3 based on generative grammar,transfer model of TLA,accessibility of universal grammar in TLA,cognitive motivation of TLA and the research on L3 emotional variables),and the sociocultural dimension(the study of task modalities from the perspective of sociocultural theory);(3)scholars who play a central role in international L3 acquisition research have mainly discussed theoretical models of L3 acquisition.
