摘　　要：语码切换代价及其非对称性是双语控制研究的焦点和核心问题。通过对语言理解中语码切换诱发的(E)LAN、N400、LPC等ERP成分的综述和分析,验证了语码切换代价的存在和语码切换加工的非对称性。并指出,不同切换方向上切换加工诱发的ERP成分的潜伏期、波幅大小和脑区分布还存在较大争议;双语理解中的语码切换代价可能源自心理词典内部两种语言自下而上的激活状况和心理词典外部自上而下的认知控制。Code-switching cost and its asymmetric processing mechanism are key issues in bilingual control research.Through reviewing and analyzing the ERP components such as(E) LAN,N400,and LPC induced by code switching in bilinguals' language comprehension,this paper verifies the existence of code-switching cost and the asymmetric processing mechanism of code-switching.It is also pointed out that there is still great controversy over the latency,amplitude and brain area distribution of ERP components induced by switching processing in different switching directions.Additionally,the code-switching cost in bilingual comprehension may originate from the bottom-up activation of two languages inside the mental lexicon and the top-down cognitive control outside the mental lexicon.
