脑损伤语言认知障碍研究 ─ 认知神经心理学研究途径

Study on Language Deficits from Brain-damage：An Approach of Cognitive Neuropsychology

20世纪90年代以来，从认知神经科学的角度揭示语言及其它认知的脑机制成为科学研究的前沿与热点。研究各种脑损伤导致的特异性语言障碍，为探索语言和其它认知的结构、加工，及大脑不同部位在语言和其它认知活动中的功能增添了一条新的途径。同时也对临床失语症的诊断与康复起了很多积极的作用。汉语在世界语言体系中具有其独特性，对汉语的语言障碍及其脑机制的研究将为完善人类语义知识理论、语言的表征与加工模型有重要贡献，也为发展汉语失语症针对性的康复方案提供理论和实践基础。

Since the 90s of last century， studying the neural mechanisms of language processing from the cognitive neuroscience perspective has been a major trend in science. Cognitive Neuropsychology is a unique approach in which various types of selective language impairments due to brain damage are studied to uncover the functional architecture and processes of language， as well as the anatomical basis of such functions. This scientific approach has had great positive impacts on the clinical assessments and treatments of aphasia. Chinese has many special characteristics as a language. The research on Chinese aphasia will have important contribution to the development of theories about the human conceptual system and human language processing. It will also provide theoretical frameworks for the development of effective treatment plans for Chinese aphasic patients.
