BACKGROUND/STUDY CONTEXT: Interactions between postural control and cognitive activity as evidenced by dual-tasking studies are common, and especially pronounced in the elderly. Some authors have used this finding to suggest that posture is "cognitively penetrable."
The authors present a critical look at the "cognitive penetrability of posture" concept. The authors first trace the notion back to Pylyshyn ( 1980 , Behavioral and Brain Sciences, 3, 111-169) in the context of visual information processing.
The authors then argue that dual-tasking interference effects do not prove that posture is penetrable by cognition.
The authors conclude that it may be valid to study cognitive penetrability of posture, but that such an endeavor is served best by adopting a hierarchical model of action control.
背景/研究背景：双任务研究表明，姿势控制与认知活动之间的相互作用很常见，在老年人中尤为明显。一些作者利用这一发现表明姿势是“认知可穿透的”。
作者对“姿势的认知可穿透性”概念进行了批判性审视。作者首先在视觉信息处理的背景下将这一概念追溯到派利夏恩（1980年，《行为与脑科学》，第3卷，第111 - 169页）。
作者随后认为双任务干扰效应并不能证明姿势可被认知穿透。
作者得出结论，研究姿势的认知可穿透性可能是有意义的，但采用动作控制的层次模型最有助于开展此类研究。
