双语者语言切换代价的影响因素

抑制控制、语言熟练度、任务相关因素和工作记忆容量是双语者语言切换代价的重要影响因素。其中,抑制控制抑或语言熟练程度何者主要调节着双语者的语言切换代价成为抑制控制模型和语言特异性选择模型争论的焦点。为此,未来研究需要在二语习得年龄与语言使用情景等因素是否影响双语者的控制机制、语言切换代价与任务转换代价的本质是否相同、语言切换代价和工作记忆之间的关系及其认知可塑性等领域予以进一步探索。

The influenced factors of bilinguals' language switching costs

Inhibitory control,language proficiency,related issues of tasks and working memory are the main factors influencing language switching costs.As to the question "which factor plays a predominate role in mediating the bilingual's language switching cost,inhibitory control or language proficiency?",there is a heated debate between Inhibitory Control Model and Language-Specific Selection Model.Therefore,the related studies in the future should further explore whether the age of second language acquisition and language use influence the bilinguals' inhibitory control,whether language switching cost and task switching cost are similar in nature and the relationship between language switching cost and working memory.
