基于Citespace的言语损伤研究动态可视化分析

A Dynamic Visualization Analysis of Studies on Speech Impairment Based on Citespace

目的探究国际言语损伤研究的最新动态和热点。方法运用Citespace的可视化技术,对2010~2019年web of science-SSCI核心合集中有关言语损伤的4206篇文献进行知识图谱分析。结果言语损伤研究与语言学、病理学、神经科学等学科相交融,研究主题颇为精细广泛;近年言语损伤研究的热点为“儿童”、“失语症”、“听力障碍”、“特殊言语障碍”、“自闭症”、“工作记忆”、“帕金森病”等;言语损伤的重点研究对象为儿童和老年人两大群体。结论言语损伤研究的跨学科交融性颇为显著,言语损伤和病理语言学、语言学以及神经科学结合是研究趋势和前沿。儿童和老年人这两大群体,是研究言语障碍早期干预和治疗的重大突破点。

Objective Explore the latest developments and hotspots in international speech impairment research.Method This article gives a mapping-knowledge-domain analysis of 4206 journal articles on speech impairment retrieved from Web of Science(SSCI and A&HCI)between 2010-2019 by means of Citespace,an information visualization technology.Results The researches of speech impairment infiltrate into other subjects like linguistics,pathology,neuroscience and other disciplines,and the research topics are quite extensive;The research hotspots of speech impairment in the past ten years were“children”,“aphasia”,“hearing impairment”,“special speech disorder”,“autism”,“working Memory”,“Parkinson’s disease”,etc;The main research object groups of speech impairment are children and the elderly.Conclusion The interdisciplinary integration of speech impairment is quite remarkable,and the combination of speech impairment and pathological linguistics,linguistics or neuroscience is the research trend.The two groups of children and the elderly are major breakthrough points in the study of early intervention and treatment of speech impairment.
