摘要: 20世纪90年代以来,采用ERP技术对人类工作记忆脑机制的研究已取得大量的成果。主要探讨了特定类型的工作记忆(词语、空间、客体工作记忆)是否存在与其贮存、复述以及中央执行功能相关的特异性ERP成分,并从它们的时间进程及头皮分布来考察工作记忆的心理过程和神经机制。研究结果对于Baddeley的认知结构模型提供了有益的修正和补充。

Abstract: Working memory as one of the most important cognition processes has been always attracting a nice bit of interest in cognitive neuroscience field. Researchers used ERP technique to examine the temporal course and scalp activity area of storage, rehearsal and central executive processing in working memory. A number of ERP studies indicated that the slow cortical potentials are specific to the kind and amount of information retained in the working memory, and the positive difference wave (Pd) is related to the updating function of the central executive. Overall these results validate and reinforce Baddeley’s working memory model.

Key words: working memory, event-related potentials, storage, rehearsal, central executive
