关于活动参与和认知绩效之间关系的文献非常丰富，但尚无定论。一些研究报告说，更高的活动参与度导致更低的认知下降;其他研究报告没有功能联系，或者更高的认知表现导致活动参与度下降较少。我们首先讨论一些方法和分析功能，可能有助于不同的结果。然后，我们应用纵向动态结构方程模型的五个重复测量的瑞士跨学科纵向研究最古老的。知觉速度和语言流畅性任务的性能进行了分析，与六个不同的活动综合得分。结果表明，增加媒体和休闲活动的参与可能会减少知觉速度的下降，但不是在言语流畅性或性能，而认知性能不影响活动参与的变化。
The literature about relationships between activity engagement and cognitive performance is abundant yet inconclusive. Some studies report that higher activity engagement leads to lower cognitive decline; others report no functional links, or that higher cognitive performance leads to less decline in activity engagement. We first discuss some methodological and analytical features that may contribute to the divergent findings. We then apply a longitudinal dynamic structural equation model to five repeated measurements of the Swiss Interdisciplinary Longitudinal Study on the Oldest Old. Performance on perceptual speed and verbal fluency tasks was analyzed in relation to six different activity composite scores. Results suggest that increased media and leisure activity engagement may lessen decline in perceptual speed, but not in verbal fluency or performance, whereas cognitive performance does not effect change in activity engagement.
