Participants in two studies conducted by Salthouse (in press) were called 2 to 182 days after participation and asked to describe the activities that they had performed in the previous study. Hierarchical regression analyses were used to examine the prediction of activity recall from age, speed, and retention interval. Overall, age was associated with 20% of the variance in activity recall, and retention interval was associated with 19%, but there was no significant interaction of age and retention interval. When perceptual speed was entered into the regression equation before age, the age-related variance was reduced by 70%. A small, but statistically significant, amount of age-related variance in activity memory remained after controlling for speed and retention interval.
索尔特豪斯（即将出版）进行的两项研究中的参与者在参与研究2至182天后被召回，并被要求描述他们在之前研究中所进行的活动。采用层次回归分析来检验从年龄、速度和保留间隔对活动回忆的预测。总体而言，年龄与活动回忆方差的20%相关，保留间隔与19%相关，但年龄和保留间隔之间没有显著的交互作用。当在年龄之前将感知速度纳入回归方程时，与年龄相关的方差减少了70%。在控制了速度和保留间隔后，活动记忆中仍存在少量但在统计学上显著的与年龄相关的方差。
