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。
Research on the mechanism of language processing is mainly based on oral language research. Since sign language has gained independent linguistic status in foreign countries, the study of sign language can help us to understand the characteristics of language better, so as to judge whether the linguistic features derived from previous studies are the features of spoken language or auditory language . In fact, studies have successively demonstrated the similarities of sign language and colloquialism in brain processing and found corresponding support in the nervous system: for example, both languages activate the processing of the superior left circumflex network system . However, in addition to common ground, researchers also sought to further discover the differences in processing between the two. After all, sign language and spoken language are languages that use different information channels. Studying their differences can help us better understand the generality of languages and help us better understand the particularities of language processing and thus promote deafness.
