A total of 1,576 adults between 18 and 95 years of age performed a battery of cognitive tests and the Connections version of the Trail Making Test twice, with an average interval between assessments of 2.5 years. Consistent with previous results, speed ability and fluid cognitive ability were strongly correlated with trail making performance. Neither speed nor fluid cognitive ability at the first occasion predicted longitudinal changes in trail making performance, but there were significant correlations between the changes in these abilities and the changes in trail making performance. These results indicate that individual differences in speed and fluid cognitive abilities are associated with individual differences in trail making performance both at a single point in time (cross-sectional differences) and in the changes over time (longitudinal changes).
共有 1576 名 18 至 95 岁的成年人进行了一系列认知测试和连线测试(中文版),两次测试的平均间隔为 2.5 年。与之前的结果一致,速度能力和流体认知能力与连线测试表现密切相关。第一次测试时的速度和流体认知能力都不能预测连线测试表现的纵向变化,但这些能力的变化与连线测试表现的变化之间存在显著的相关性。这些结果表明,速度和流体认知能力的个体差异与连线测试表现的个体差异有关,无论是在单一时间点(横断面差异)还是在随时间变化(纵向变化)上。
