纳西——汉双语儿童在言语中的词汇选择机制

On the Lexical Selection Mechanism in the Speech of Naxi-Chinese Bilingual Children

本研究通过考察图片命名任务中的语码切换代价,探讨小学纳西——汉双语者在双语言语产生中的词汇选择机制。结果表明:1.对于纳西语作为基本熟练,汉语作为相对熟练的不平衡双语者而言,用纳西语和汉语命名图片时,存在切换代价的不对称性,切换至相对熟练语言(汉语)的代价显著大于切换至基本熟练语言(纳西语);2.在基本水平的实验任务中,用纳西语和汉语命名图片时,存在切换代价的不对称性;在范畴水平的实验任务中,用纳西语和汉语命名图片时,不存在切换代价的不对称性;3.任务水平影响词汇的选择机制,但语言的熟练程度并没有影响词汇的选择机制。

This paper presents a study on the lexical selection mechanism in bilingual speech production of the bilingualists of the Naxi and the Chinese languages at primary school through language switch costs in the picture naming tasks. Results of the study show：1） for unbalanced bilingualists virtually fluent in Naxi but only relatively fluent in Chinese,asymmetrical switching costs were observed when naming pictures in Naxi and Chinese – it costs notably more to switch to the relatively fluent language（ Chinese）than to the virtually fluent language（ Naxi）; 2） asymmetrical switching was observed when naming pictures in Naxi and Chinese in the basic- level experiment while no asymmetrical switching was observed when naming pictures in Naxi and Chinese in the category- level experiment; and 3） level of the tasks influences the lexical selection mechanism but language fluency does not.
