老年人运动技能学习的个体差异很大。由于参与者特征（如年龄、认知）和任务相关因素（如任务性质、技能预训练水平）之间的相互作用，确定这些个体差异的性质仍然具有挑战性，因此很难确定合理的因果关系。本研究通过使用中介分析来检验视觉空间记忆与训练后上肢功能性任务中粗大和精细运动部分一个月的保留之间的合理因果推理，从而解决了这些相互矛盾的解释。结果表明，更好的视觉空间记忆导致更多的精细运动技能的保留，而不是大运动技能，扩展了先前在老年人中的相关研究，并为未来的干预措施提供了信息，以最大化老年人群的运动学习。
There is high inter-individual variability in motor skill learning among older adults. Identifying the nature of these individual differences remains challenging due to interactions between participant characteristics (e.g., age, cognition) and task-related factors (e.g., nature of task, level of skill pre-training), making it difficult to determine plausibly causal relationships. This study addresses these competing explanations by using mediation analysis to examine plausible causal inference between visuospatial memory and one-month retention of both gross and fine motor components of a functional upper-extremity task following training. Results suggest that better visuospatial memory results in more retention of fine but not gross motor skill, expanding on previous correlational studies in older adults and informing future interventions for maximizing motor learning in geriatric populations.
