本研究探讨了视觉空间工作记忆、执行功能和空间能力之间的关系。167名参与者进行了视觉空间短期记忆（STM）和工作记忆广度任务，执行功能任务，以及一组纸笔测试的空间能力，加载3个相关但可区分的因素（空间可视化，空间关系和感知速度）。实证因素分析结果表明，在视觉空间领域，加工和储存工作记忆任务和储存型短时记忆任务同样影响执行功能，且不能明显区分。这些结果提供了一个对比与现有的证据，从言语领域和支持的建议，视觉空间画板可能是密切相关的中央执行。此外，结构方程模型的结果支持的预测，而他们都牵连一定程度的视觉空间存储，3个空间能力因素的不同程度的行政参与（最高的空间可视化和最低的感知速度）。这样的结果突出了有用的工作记忆的角度来表征认知能力的性质，更普遍的是，人类的智力。
This study examined the relationships among visuospatial working memory (WM) executive functioning, and spatial abilities. One hundred sixty-seven participants performed visuospatial short-term memory (STM) and WM span tasks, executive functioning tasks, and a set of paper-and-pencil tests of spatial abilities that load on 3 correlated but distinguishable factors (Spatial Visualization, Spatial Relations, and Perceptual Speed). Confirmatory factor analysis results indicated that, in the visuospatial domain, processing-and-storage WM tasks and storage-oriented STM tasks equally implicate executive functioning and are not clearly distinguishable. These results provide a contrast with existing evidence from the verbal domain and support the proposal that the visuospatial sketchpad may be closely tied to the central executive. Further, structural equation modeling results supported the prediction that, whereas they all implicate some degree of visuospatial storage, the 3 spatial ability factors differ in the degree of executive involvement (highest for Spatial Visualization and lowest for Perceptual Speed). Such results highlight the usefulness of a WM perspective in characterizing the nature of cognitive abilities and, more generally, human intelligence.
