【摘要】：本研究探讨个体二语语音辨别能力的差异来源。以母语为粤语(L1)的粤语-普通话双语者为研究对象,根据被试的普通话二语(L2)的辨音能力,将其分为二语辨音强组(GP)和二语辨音弱组(PP),以失匹配负波(MMN)为电生理指标通过ERP实验分别考察了两组被试对语音和一般声音(复合音)的辨别差异。结果发现:无论是对母语语音辨别还是对跨语系第三种语言的语音辨别,二语辨音强组的被试诱发的MMN波幅都显著大于二语辨音弱组的被试;进一步,对一般复合音的辨别,二语辨音强组的被试诱发的MMN波幅也显著大于二语辨音弱组的被试。研究结果表明:二语语音辨别的个体差异不仅可以追溯到一般语音层面的辨音能力差异,还可以进一步追溯到一般声音层面的复合音辨音能力差异。
[Abstract]:This study explores the sources of differences in individual L2 phonological discrimination.The subjects of this study were Cantonese / Putonghua bilinguals whose mother tongue was Cantonese / L1).It was divided into two groups: the second language strong group (GP) and the second language group (weak group). Using mismatched negative wave (MMN) as the electrophysiological index, the difference of speech and general sound (complex sound) between the two groups was investigated by ERP experiment.The results showed that the amplitude of MMN in the group of strong second language recognition was significantly higher than that in the group with weak second language, whether it was for the speech discrimination of mother tongue or the third language of cross-language.The amplitude of MMN induced by the strong second language discrimination group was significantly higher than that of the second language weak group.The results show that the individual differences in second language speech discrimination can be traced back not only to the differences in speech recognition at the general level, but also to the differences in the recognition of complex sounds at the general sound level.
