【摘要】中央执行性系统作为工作记忆的核心成分被认为是可分离的，转换、刷新和抑制被认为是三种相对独立的中央执行功能。在相关研究中，跟踪任务、字母（数字）活动记忆任务和n-back  范式一般用来评估刷新功能；评估转化功能所采用的研究范式有：加法-减法转换任务、数字-字母转换任务、数字转换任务以及局部-全局任务；Stroop  任务、停止信号任务和Go/No-Go  任务被认为是测量和评估抑制功能的经典范式。进一步的研究需要做的工作应该包括：改进相关研究范式，进行工作记忆中央执行系统的全面评估；开发针对学习障碍儿童和老年人等特殊被试的中央执行功能评估工具；建立中央执行系统的认知神经评价指标和体系；开展中央执行系统训练研究。

【Abstract】The central executive system is  the core component of working memory; shifting, updating and inhibition process  are considered as three relatively independent functions. Keep track task、letter  memory task and n-back paradigm are generally used to evaluate the function of  updating; The function of shifting adopts four research paradigms: plus-minus  task、number-letter task、more-odd shifting and stroop task、stop-signal task and  Go/No-GO task are considered to be the classical paradigms inhibition of  measurement and assessment. Further research need to improve the related  research paradigm, evaluate central executive system of working memory, to  develop the central executive system assessment tool for learning disabled  children and the aged as well as special subjects, build cognitive neuroscience  evaluation index and system of central executive system and carry out the  training research of system in future.
