摘要
目的:近年来,国外对言语流畅性的研究逐渐增多,特别是在神经生理学方面,受到越来越多的关注,在临床上也占据重要地位。本文旨在通过综述国外关于言语流畅性的研究及进展,为国内的言语流畅性研究提供某些启示。资料来源:应用计算机检索Sciencedirect1990-07/2005-05中与言语流畅性相关的文献,检索词为“verbalfluency”,并限定文献为英文。资料选择:对资料进行初审,选取文章标题中含有“verbalfluency”的英文文献,纳入标准:①对言语流畅性结构及功能的研究。②对言语流畅性影响因素的研究。③对言语流畅性神经生理基础的研究。资料提炼:共收集到651篇关于言语流畅性的文章,纳入19篇用于综述。资料综合:言语流畅性的结构要素包括音位流畅性和语义流畅性。言语流畅性测验为脑损伤提供定位诊断的症状学依据,为高级神经机能康复提供心理学依据。言语流畅受多方面因素影响,具体因素有脑的整体功能、言语智力和教育与年龄因素,言语流畅性的神经生理机制为:音位流畅性相对依赖额叶结构,语义流畅性相对依赖颞叶结构。结论:言语流畅性是人类言语能力的一个衡量标准,可作为脑损伤患者言语诊断的一个指标。同时对言语流畅性的研究将有助于深入了解人类的认知能力。
OBJECTIVE： Recently ,more and more oversea studies has been done on verbal fluency, especially in the field of neurophysiology. These studies has received more and more attention and played an important role in clinical research. The paper summarizes the foreign researches on verbal fluency and surveys the development of it, which can provide some inspiration for the future domestic research. DATA SOURCES： Sciencedirect was searched with computer to collect the articles about verbal fluency published between July 1990 and May 2005 with the key words ＂verbal fluency＂ in English, STUDY SELECTION： The data were preliminary checked and the English articles were selected if their headlines included ＂verbal fluency＂. Inclusion criteria： ① those about the structure and function of verbal fluency, ② those about the influencing factors of verbal fluency, and ③ those about the neurephysiological mechanism of verbal fluency. DATA EXTRACTION： 651 articles about verbal fluency were collected in total. Nineteen articles were catered for reviews, DATA SYNTHESIS： Verbal fluency included two main structural factors： phonemic fluency and semantic fluency. It could provide some proof to diagnose where the brain damaged and help to improve the advanced neurefunction. On the other hand, verbal fluency was influenced by several factors： the whole function of the brain, verbal intelligence quotient （IQ）, education and age. And its neurophysiological mechanism was that phonemic fluency relied more on the intact frontal lobe than semantic fluency does, but semantic fluency depended more on the temporal lobe comparing to phonemic fluency. CONCLUSION： Verbal fluency that is a useful criterion to assess verbal ability of human can be an index of what degree the verbal deficit of brain damage patient achieved. In addition, the research on verbal fluency can help to further understand the cognitive ability of human.
