本研究通过验证性因素分析，检验了六种执行功能（语言存储和处理协调、视觉空间存储和处理协调、双任务协调、策略检索、选择性注意和转移）的可分离性及其关系。 180 名参与者执行了一组主要评估每个目标功能的任务。结果表明，最初考虑的六个功能中有五个是可区分的，尽管相关的结构，其中一个功能结合了抑制和策略检索过程。这些分析未能揭示双任务性能背后的单一双任务协调能力。这些发现为中央执行机构分为几个职能提供了进一步的支持，并强调需要从一般职能内部的分离和其中一些职能之间的具体相互作用来研究执行职能。 (C) 2008 Elsevier B.V. 保留所有权利。
The present study examined the separability of six executive functions (verbal storage-and-processing coordination, visuospatial storage-and-processing coordination, dual-task coordination, strategic retrieval, selective attention, and shifting) and their relationships, by means of confirmatory factor analysis. A set of tasks thought to primarily assess each target function was administered to 180 participants. The results demonstrated that five of the six functions initially considered were distinguishable albeit related constructs, with one of these functions combining inhibitory and strategic retrieval processes. The analyses failed to reveal a single dual-task coordination ability underlying performance on the dual-tasks. These findings provide further support for the fractionation of the central executive into several functions and also stress the need to approach executive functioning in terms of both dissociations within general functions and specific interactions between some of these functions.
