老年时积极参与的生活方式是否会缓解认知能力下降，老年时高认知功能是否会增加保持积极参与的生活方式的可能性，或者两者兼而有之？作者通过应用结构方程模型来检验动态假设，即双重变化分数模型（J. J. McArdle & F。Hamagami，2001），以及来自柏林老化研究的3次纵向数据（时间1：n = 516，年龄范围= 70-103岁）。结果表明，在一个双变量系统的感知速度和社会参与，与年龄和社会生物学地位的协变量，以前的分数的社会参与影响随后的变化，感知速度，而相反的不成立。结果支持这一假设，即从事和积极的生活方式在老年和非常老的年龄可能会减轻知觉速度下降。
Does an engaged and active lifestyle in old age alleviate cognitive decline, does high cognitive functioning in old age increase the possibility of maintaining an engaged and active lifestyle, or both? The authors approach this conundrum by applying a structural equation model for testing dynamic hypotheses, the dual change score model (J. J. McArdle & F. Hamagami, 2001), to 3-occasion longitudinal data from the Berlin Aging Study (Time 1: n = 516, age range = 70-103 years). Results reveal that within a bivariate system of perceptual speed and social participation, with age and sociobiographical status as covariates, prior scores of social participation influence subsequent changes in perceptual speed, while the opposite does not hold. Results support the hypothesis that an engaged and active lifestyle in old and very old age may alleviate decline in perceptual speed.
