摘　　要：双语者在词汇选择过程中进行两种语言之间的转换称为语码切换。实验1采用语码切换范式,探讨不同熟练程度傣-汉双语小学生的语码切换代价。结果发现,傣-汉双语小学生在语码切换任务中产生了切换代价,且熟练与非熟练双语小学生均存在切换代价的不对称现象,切换至汉语的代价大于切换至傣语的代价。基于实验1发现的语码切换代价不对称现象,实验2选取刺激-刺激和刺激-反应相容任务,对傣-汉双语小学生的语码切换代价的抑制控制机制进行深入研究。结果发现,熟练双语小学生的抑制控制能力比非熟练双语小学生强,二者的差异主要表现在反应抑制阶段。The lexical selection of two languages for bilinguals is called language switching. Experiment 1 used language-switching paradigm to investigate the switching costs of proficient and non-proficient Dai-Han bilinguals. The results revealed that switching cost of both proficient and non-proficient bilinguals were asymmetrical. Moreover, cost of switching into Han were larger than cost of switching into Dai. In order to further study the asymmetrical of switch costs in lexical selection, Experiment 2 used a combined stimulus-stimulus and stimulus-response compatibility paradigm that investigated the mechanism of inhibitory control. The result indicated a difference of inhibitory control that emerged in the response inhibition stage with interference by Han lexicons. Compared to NPB, PB showed inhibition control advantage.
