Abstract: In the present study, we used the task of cross-language repetition priming paradigm, to investigate the characteristics of semantic and lexical representation for highly proficient and less proficient Tibetan-Chinese bilinguals. In semantic judgment task, the participants′ response time of the words studied is significantly shorter than that of the words unstudied in the test phase. Both highly proficient and less proficient Tibetan-Chinese bilinguals have apparent repetition priming effect within language and cross-language. In lexical judgment task, it was found that the response time of the words studied is significantly shorter than that of the words unstudied within languge, showing repetitior pring effect, but not in the cross-language cordition. The present study indicates that for Tibetan-Chinese bilinguals, semantic representation is shared, while lexical representation is separation. Highly proficient and less proficient Tibetan-Chinese bilinguals have the same bilingual language representation mode. In the cross-language priming, the highly proficient Tibetan-Chinese bilinguals are faster than the less proficient person.

Key words: Tibetan-Chinese bilinguals, semantic representation, lexical representation, long-term cross-language repetition priming.

摘要： 使用跨语言长时重复启动实验范式,考察熟练和非熟练藏-汉双语者的语义和词汇表征的特点。在完成语义判断任务时,被试在测验阶段对已学词的反应时显著短于未学词,且熟练和非熟练藏-汉双语者都表现出明显的同语言和跨语言长时重复启动效应。在完成词汇判断任务时,同语言条件下已学词的反应时显著短于未学词,出现长时重复启动效应;跨语言条件下已学词的反应时显著长于未学词,未获得长时重复启动效应。结果表明,藏-汉双语者语义表征共同存储、词汇表征独立存储;熟练和非熟练藏-汉双语者语义和词汇表征模式相同;藏-汉双语熟练者比非熟练者跨语言启动更快。
