摘要
中央执行性系统作为工作记忆的核心成分,主要负责工作记忆中的控制性加工,在工作记忆中起着关键的作用;中央执行系统是可分离的,转换、刷新和抑制是三种相对独立的中央执行功能,分别起着不同的作用;认知神经科学关于工作记忆的研究表明,工作记忆的执行功能主要由前额叶调控,P300是反映中央执行系统功能的典型ERP成分;对工作记忆中央执行性系统概念的辨析、相关研究范式的改进以及中央执行系统的训练将成为该领域研究的重点。
The central executive system is the most important component of working memory,which is simply treated as a pool of general processing capacity.The core of the working memory model is the central executive system.The central executive system is separable and it consists of three relatively independent functions which are shifting,updating and inhibition process.Cognitive neuroscience research indicates that executive function is mainly controlled by prefrontal Cortex.P300 is regarded as the typical ERP effect of the central executive function.The concept and research paradigm of the central executive system will be improved,and also how to train the central executive system in this field will be the focus in the future.
