本研究验证了一种假设，即衰老导致的感觉运动功能的认知渗透有助于成人在空间导航能力上的年龄差异。跑步机前投射出迷宫般的虚拟博物馆。16名20-30岁的男性和16名60-70岁的男性在有无支撑的情况下，在城市街区或变化的地形上进行寻路任务。步行支持可减轻航海学习中与年龄相关的减退。只有老年人的航行负荷增加了躯干角度的变异性。尽管在寻找位置方面表现出色，但空间知识的年龄差异依然存在。仅对年轻人而言，城市街区地形比可变地形更容易，这表明与年龄相关的对空间关系学习的依赖程度存在差异。支持老年人导航能力的尝试应该考虑到感觉运动/认知相互作用和导航活动的质量差异。
This study tests the hypothesis that aging-induced cognitive permeation of sensorimotor functions contributes to adult age differences in spatial navigation performance. Virtual maze-like museums were projected in front of a treadmill. Sixteen 20-30-year-old men and sixteen 60-70-year-old men performed a way-finding task in city-block or variable topographies while walking with or without support. Walking support attenuated age-related decrements in navigational learning. Navigation load increased trunk-angle variability for older adults only. Age differences in spatial knowledge persisted despite perfect place-finding performance. City-block topography was easier than variable topography for younger adults only, indicating age-related differences in reliance on spatial relational learning. Attempts at supporting older adults' navigation performance should consider sensorimotor/cognitive interactions and qualitative differences in navigational activity.
