语言学视角下的失语症研究现状与发展趋势——基于Bibliometrix的可视化分析

Current status and development trends of aphasia research from the linguistic perspective Bibliometrix-based visual analysis

失语症的语言学研究是神经语言学领域的重要研究内容,已取得大量的理论及应用研究成果。本研究基于SSCI数据库文献,借助R语言的文献计量软件工具包Bibliometrix对1983—2022年期间的3,721篇失语症的语言学研究文献进行可视化分析。通过分析语言学视角下的失语症研究高产期刊、高产作者、国家合作、关键词共现、历史被引文献、高被引文献等,本文梳理了失语症的语言学研究现状、热点和趋势。研究发现:(1)失语症的语言学研究论文数量整体呈现上升趋势。Aphasiology和Brain and Language为高产期刊,Roelien Bastiaanse、Cynthia K.Thompson等学者发文量较多。美国在该领域国际合作中的影响力最大;(2)研究热点主要集中于失语症患者的言语表现,不同类型的失语症研究以及失语症患者的语言康复训练;(3)实证研究占主导地位,采用的研究手段主要包括fMRI、ERP、PET等。

The linguistic research on aphasia,as an important field of neurolinguistic studies,has been the subject of a large body of theoretical and applied research.The present study visualized and analyzed 3,721 papers concerning linguistic research on aphasia from SSCI database during the period 1983-2022 with the help of Bibliometrix,a bibliometric software package in R.Research status,hot topics,and trends of linguistic research on aphasia were sorted out by analyzing the most cited journals and authors,country collaboration,co-occurring keywords,historical direction citation network,and the highly cited documents of aphasia research from the linguistic perspective.The study found that:(1)The number of papers regarding linguistic research on aphasia was on the rise overall.Aphasiology was the most fruitful journal.Roelien Bastiaanse was the most productive author.The United States exerted the greatest influence in international collaboration of this field;(2)Research hotspots mainly focused on the language performance of aphasic patients,research on various types of aphasia,and language rehabilitation training for aphasic patients;(3)Empirical studies were dominant,employing research techniques such as fMRI,ERP and PET.
