据报道，一项实验检查了滞后效应与年龄相关的差异及其与保留间隔的关系。总共 30 名年轻人和 30 名老年人接受了一次呈现的配对和两次呈现的配对，这些配对在短保留间隔（在最后一次呈现配对与其测试之间插入 2 对）或在较长保留间隔（在最后一次呈现配对与其测试之间插入 20 对）之后以连续提示回忆范式进行测试。此外，两次出现的对被 0、1、4、8 或 20 个中间对分开。结果重复了 Glenberg 报道的保留间隔和滞后之间的相互作用（1976，言语学习和言语行为杂志，15, 1-16）。此外，尽管老年人的整体回忆表现明显低于年轻人，但他们的数据在均值模式方面与年轻人非常相似。使用数学建模程序将数据拟合到 Estes 的刺激波动模型。该建模过程的结果表明，与年轻人相比，老年人（a）在给定时间点编码的上下文信息较少，并且（b）随时间变化的上下文波动率较慢。
An experiment is reported that examines age-related differences in the lag effect and its relation to retention interval. A total of 30 young and 30 older adults received both once-presented pairs and twice-presented pairs that were tested in a continuous cued-recall paradigm either after a short retention interval (2 pairs intervening between the last presentation of a pair and its test) or a long retention interval (20 pairs intervening between the last presentation of a pair and its test). In addition, the twice-presented pairs were separated by either 0, 1, 4, 8, or 20 intervening pairs. The results replicated the interaction between retention interval and lag that has been reported by Glenberg (1976, Journal of Verbal Learning and Verbal Behavior, 15, 1-16). Furthermore, although the older adults performed considerably lower than the younger adults in overall recall performance, their data were remarkably similar to the younger adults in the patterning of means. A mathematical modeling procedure was used to fit the data to Estes' stimulus fluctuation model. The results of this modeling procedure suggest that, compared with younger adults, older adults (a) encode less contextual information at a given point in time and (b) have a slower rate of contextual fluctuation across time.
