摘　　要：语码切换代价是人们研究双语词汇选择和跨语言交互认知神经机制的量化指标,是目前双语认知控制研究的焦点之一。研究者构建的抑制控制模型、双语交互激活+模型能分别为语言产出和语言理解中的切换代价提供解释框架。相关研究表明,双语者在进行语码切换时通常会产生非对称性切换代价,体现在不同方向切换诱发的ERP成分的显著差异上。但这种非对称性并非绝对,还受抑制控制能力、L2水平、任务预期性、准备时间、语境等多方面因素的影响。今后的研究可从这些因素入手,进一步探讨语码切换及双语控制的神经机制,丰富现有的理论模型和研究成果。Code-switching cost is a quantitative indicator of the cognitive neural mechanism of bilingual word selection and cross-language interaction,hence one of the focus issues in bilingual cognitive control research at present.The Inhibitory Control(IC)model and Bilingual Interactive Activation+constructed by the researchers provides an explanatory framework for the generation of code-switching costs in language production and language understanding,respectively,even though they meet some challenges.In recent years,relevant studies have shown that bilinguals′code-switching process usually induce asymmetric switching costs,reflected in the significant difference of ERP components induced by switching directions.However,this asymmetry is not absolute,and is influenced by many factors such as inhibitory control ability,L2 level,task anticipation,preparation time,context and other dimensions.Future studies could further explore the neural mechanism of code-switching and bilingual control based on these differences to perfect the current explanation models and broaden the research topics on code-switching.
