【摘要】：本研究采用功能性磁共振脑成像 (fMRI)技术 ,首次以中国手语作为实验材料 ,通过外显手语和内隐手语刺激的比较 ,探查中国手语在聋人左、右半球大脑皮层的功能定位情况。研究的结果表明 :( 1 )手语与有声语言的绝大多数功能区是叠合的 ,与正常人和美国手语的研究结果相似 ,聋人的视觉性语言优势半球也是在左半球。语言的半球单侧化现象以及语言大脑功能定位区很少受语言模式特征的影响。 ( 2 )聋人手语的信息加工过程包括语言加工和视觉空间认知 ,语言加工模块与空间认知加工模块之间是存在一定的共享成分 ,这为跨模块可塑性理论提供了实证依据。 ( 3 )研究进一步表明 ,手语是一种有助于促进聋人大脑语言区活动的刺激 ,倡导在聋教中采用“双语教育”和强调中国手语的语言地位
[Abstract]:In this study, functional magnetic resonance imaging (fMRI) technique was used to investigate the left of Chinese sign language in deaf people by comparing explicit sign language with implicit sign language stimulation for the first time. Functional localization of the right hemisphere cortex. The results show that: (1) most functional regions of sign language and acoustic language are superimposed, similar to those of normal people and American sign language, and the dominant hemisphere of visual language of deaf people is also in the left hemisphere. The hemispheric lateralization of language and the functional localization of the language brain are rarely affected by language pattern characteristics. (2) the information processing process of deaf sign language includes language processing and visual spatial cognition. There is a certain shared component between language processing module and spatial cognitive processing module, which provides an empirical basis for cross-module plasticity theory. (3) the study further shows that sign language is a kind of stimulation which helps to promote the activity of the deaf people's brain language area, and advocates the use of "bilingual education" in deaf education and emphasizes the language status of Chinese sign language.
