【摘要】：本文采用事件相关电位技术,在词图匹配任务下考察汉语声韵调和音节结构在聋人词汇阅读中的作用。研究发现,与听人相比,聋人被试并未出现反映早期语音加工的N200和P2成分,但在N400上,声母失匹配与语音不相关类型之间构成显著差异,表明在时程上聋人的语音加工可能晚于听人;另外,两组被试四种失匹配类型(声母/韵母/声调失匹配及语音不相关)之间在N400和LPC成分是否构成显著差异的情况也不相同,表明聋人在汉字阅读时声韵调等所起的作用可能与听人不同。
[Abstract]:In this paper, the role of Chinese phonological and syllable structures in lexical reading of deaf people is investigated by means of event-related potential technique under the word map matching task. The study found that deaf people did not have N200 and P2 components that reflected early speech processing, but at N400, there was a significant difference between initial mismatch and uncorrelated speech types. The results showed that the speech processing of deaf people may be later than that of hearing people, and whether the four mismatch types (consonant / vowel / tone mismatch and phonetic disassociation) constituted significant difference between N400 and LPC components in the two groups were also different. It shows that deaf people may play different roles in Chinese character reading.
