摘　　要：探究双语者对两种语言系统的加工过程,尤其是双语者有效地从一种语言切换到另一种语言即双语语码切换,是双语研究领域的关键科学问题。随着神经影像学技术的快速发展,双语加工尤其是语码切换研究取得了重要的进展,但是对于双语语码切换的内部产生机制,目前还没有一致的结论。从神经心理和影像学角度开展的双语切换研究可以从时间和空间两方面阐明双语者进行语码切换的过程和大脑机制,为双语者语码切换的产生机制提供直接的证据。本文从事件相关电位技术、功能性磁共振成像技术和脑磁图技术三个方面分析双语语码切换的研究,并对未来研究方向及其技术手段进行展望。In the field of bilingualism research,a key scientific question is how bilinguals process two language systems,particularly the effective switch from one language to another,namely bilingual code switching.With the rapid development of neuroimaging techniques,important progresses have been made in bilingual processing studies,especially in code switching.However,consensus has not been achieved regarding the mechanisms of bilingual code switching.Bilingual switching studies using neuropsychological and neuroimaging techniques have gained insights into the temporal and spatial features of the language switching process and the neurological mechanism,which provide direct evidence for the generation mechanism of bilingual code switching.
