Aging coincides with a decline in navigation and wayfinding abilities, but it is unclear to what extent factors relating to a given individual may contribute to mitigating this decline. The present study aims to analyze how older adults' objective cognitive functioning and self-reported subjective wayfinding inclinations predict their navigation performance. Sixty-four older adults were assessed on their general cognitive functioning (all scoring from 22 to 30 on the Montreal Cognitive Assessment, MoCA), visuospatial working memory (VSWM), and perspective-taking abilities. Their self-assessed wayfinding inclinations (such as their sense of direction, pleasure in exploring places, and spatial anxiety) were also examined. Then participants learned a path in an environment from video navigation and performed a route repetition task (which maintained the same egocentric perspective as the learning phase), and a sketch map task (which involved switching from an egocentric perspective used in the learning phase to an allocentric perspective). The results showed that positive wayfinding inclinations (in terms of pleasure in exploring) related to participants' route repetition accuracy, while their general cognitive performance (MoCA scores) related to their sketch map drawing accuracy. Individual factors such as cognitive functioning and wayfinding inclinations relate differently to older people's navigation performance, depending on the demands of the tasks used to test their environment learning.
衰老与导航和寻路能力的下降同时出现,但尚不清楚与特定个体相关的因素在多大程度上可能有助于减轻这种下降。本研究旨在分析老年人的客观认知功能和自我报告的主观寻路倾向如何预测他们的导航表现。对64名老年人的一般认知功能(在蒙特利尔认知评估量表,即MoCA上的得分均在22至30分之间)、视觉空间工作记忆(VSWM)和换位思考能力进行了评估。还考察了他们自我评估的寻路倾向(如方向感、探索地点的乐趣和空间焦虑)。然后,参与者通过视频导航在一个环境中学习一条路径,并执行路线重复任务(保持与学习阶段相同的自我中心视角)和草图绘制任务(涉及从学习阶段使用的自我中心视角切换到异我中心视角)。结果表明,积极的寻路倾向(就探索的乐趣而言)与参与者的路线重复准确性相关,而他们的一般认知表现(MoCA得分)与他们的草图绘制准确性相关。认知功能和寻路倾向等个体因素与老年人的导航表现的关系各不相同,这取决于用于测试他们环境学习的任务要求。
