The current study investigated the mechanism of language switching in unbalanced visual unimodal bilinguals as well as balanced and unbalanced bimodal bilinguals during a picture naming task. All three groups exhibited significant switch costs across two languages, with symmetrical switch cost in balanced bimodal bilinguals and asymmetrical switch cost in unbalanced unimodal bilinguals and bimodal bilinguals. Moreover, the relative proficiency of the two languages but not their absolute proficiency had an effect on language switch cost. For the bimodal bilinguals the language switch cost also arose from modality switching. These findings suggest that the language switch cost might originate from multiple sources from both outside (e.g., modality switching) and inside (e.g., the relative proficiency of the two languages) the linguistic lexicon.
当前的研究调查了非平衡视觉单语双语者以及平衡和非平衡双语者在图片命名任务中语言切换的机制。所有三组在两种语言之间都表现出显著的切换代价，平衡双语者的切换代价是对称的，而非平衡单语双语者和双语者的切换代价是不对称的。此外，两种语言的相对熟练程度而非绝对熟练程度对语言切换代价有影响。对于双语者来说，语言切换代价也源于模态切换。这些发现表明，语言切换代价可能源于语言词汇之外（如模态切换）和之内（如两种语言的相对熟练程度）的多个来源。
