国外对手语的脑加工机制研究

On the Foreign Brain Mechanism of Sign Language Processing

关于语言的脑加工机制研究主要是根据口语语言的研究所获得的。既然手语在国外已经获得了独立的语言地位,因此可以通过对手语语言的研究,更好地理解关于语言的特征,从而判断以往研究中得出的语言特征是否是口语或听觉语言所具有的特征。实际上,已经有研究相继表明了手语和口语在脑加工上的相似性,并在神经系统上找到了相应的支持:比如这两种语言都激活了优势的左外侧裂周区网络系统的加工。不过除了共同点,研究人员也试图进一步发现二者存在的加工差异。毕竟手语与口语是使用不同信息通道的语言,对其差异性的研究,一方面可以帮助我们更好地理解语言的一般性,也可以帮助我们更好地理解语言加工的特殊性,从而促进聋人的语言发展。

The study of the brain mechanism of language processing is mainly based on the study of spoken language.The study of sign language,which has gained an independent language status abroad,helps to have a better understanding of the features of language,whether spoken language or hearing language.In reality,research has shown the similarities of sign language and spoken language in the brain mechanism of language processing,as well as the corresponding support from the nervous system.For example,these two kinds of language can both activate the language processing in the network system of the peripheral area of the left-lateral fissure.Also,researchers seek to explore the dissimilarities in the processing of these two kinds of languages using different information channels.This will help us to have a better understanding of their general and special features so as to promote the development of hearing-impaired persons＇ language.
