The aim of this study was to evaluate motor control activity (active vs. passive condition) with regards to wayfinding and spatial learning difficulties in large-scale spaces for older adults. We compared virtual reality (VR)-based wayfinding and spatial memory (survey and route knowledge) performances between 30 younger and 30 older adults. A significant effect of age was obtained on the wayfinding performances but not on the spatial memory performances. Specifically, the active condition deteriorated the survey measure in all of the participants and increased the age-related differences in the wayfinding performances. Importantly, the age-related differences in the wayfinding performances, after an active condition, were further mediated by the executive measures. All of the results relative to a detrimental effect of motor activity are discussed in terms of a dual task effect as well as executive decline associated with aging.
本研究旨在评估老年人在大型空间中进行寻路和空间学习时的运动控制活动（主动与被动条件）。我们比较了 30 名年轻参与者和 30 名老年参与者在基于虚拟现实（VR）的寻路和空间记忆（调查和路线知识）表现。在寻路表现上，年龄存在显著影响，但在空间记忆表现上没有。具体来说，主动条件恶化了所有参与者的调查测量结果，并增加了寻路表现中的年龄相关差异。重要的是，主动条件后寻路表现中的年龄相关差异，进一步被执行措施所介导。所有与运动活动的有害影响相关的结果，都将从双重任务效应以及与衰老相关的执行能力下降方面进行讨论。
