三语者的语言切换机制

The Language Switching Mechanism of Trilinguals

近十年来,有关三语研究已成为学界热点,国外涌现了丰富的研究成果。国外针对三语者语言切换的特点做了大量的实证研究,然而,这些研究结论具有较多争议。借用语言切换过程中常用的观测指标——语言切换代价和N-2重复代价,梳理现有研究结果。结合该领域的研究现状,简要展望未来研究的方向。

In the past 10 years,trilingual research has become a hot topic in academic circles,and abundant research results have emerged abroad.However,these conclusions are controversial.We use the commonly used observation indicators in the process of language switching:language switching cost and N-2 duplication cost to sort out the existing research results.Finally,the future research directions are briefly prospected.
