近十五年语言衰老研究的可视化文献计量分析

CiteSpace Analysis of the Research on Language and Ageing in the Last Fifteen Years

采用CiteSpace科学计量学方法,对2003至2017年间Web of Science(SSCI,SCI,AHCI)收录的554篇语言衰老研究论文的引文数据进行了可视化分析并绘制了相应的科学知识图谱。通过考察语言衰老研究的时间分布、学科分布、国家分布规律,梳理了该领域的重点研究课题、最新研究热点与发展变化趋势。研究显示,近年来语言衰老研究总体上呈增长趋势,主要涉及老年听觉语言理解、老年口语产出、帕金森语言障碍、老年话语分析和语言衰老神经机制五大领域。该领域呈现出研究对象多元化、研究内容纵深化和研究手段科学化的发展趋势。

Using CiteSpace,a scientometric method,this paper analyzes the co-cited references of554original research articles from Web of Science(SSCI,SCI,AHCI)published between2003and2017on language and ageing and draws science maps accordingly.This study also analyzes the amount of annual publications,the disciplines involved in this field,the most productive countries and identifies the main research areas,hot research topics and research development.Results indicate that the number of publications is increasing in recent years.The major research areas that have been identified include auditory language comprehension,language production,language deficits of Parkinson patients,discourse analysis and neural mechanisms of ageing-related language deficits.The study also reveals a progressively wider coverage of ageing population,more comprehensive research contents and more advanced research instruments in the prior research.
