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

AbstractThe central  executive system is the core component of working memory; shifting, updating and  inhibition process are considered as three relatively independent functions.  Keep track taskletter memory task and n-back paradigm are generally  used to evaluate the function of updating; The function of shifting adopts four  research paradigms: plus-minustasknumber-letter  taskmore-odd shifting and stroop taskstop-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.
