工作记忆中央执行功能研究新进展

中央执行功能是工作记忆系统中最重要却又研究最少的一个成分。对中央执行功能的研究存在神经心理学、认知行为、脑成像，以及计算模拟等多种途径。近年来研究较多的执行功能包括：双任务协调、注意转换、抑制优势反应、记忆刷新等。目前该领域的研究热点是，运用潜变量分析和脑成像等多学科的先进手段，对执行功能的可分离性和结构有效性进行研究。

Review on Central Executive of Working Memory

Central executive is the most important but least specified component of working memory. About four research approaches attempt to specify and analyse executive functions, which stem from neuropsychology, psychometric tradition, brain imaging, and computational modelling, respectively. In recent years, several executive functions have been studied, including dual-task coordination, inhibition of prepotent responses, attention switching, and memory updating, etc. Recently, latent variable analysis and neuroimaging approaches have been used to explore the diversity and validity of executive functioning construct.
