在短期记忆任务中，当目标词出现时，年轻和年长的受试者被要求执行一个动作。这种前瞻记忆任务的难度是通过改变目标事件发生之前的延迟和改变不同目标事件的数量来操纵的。当有几个不同的目标事件时，与年龄相关的成绩差异出现，但当一个目标事件出现多次时，与年龄相关的成绩差异不会出现。与年龄相关的表现差异，当它们发生时，与对目标事件较差的回顾记忆有关。研究结果通过对前瞻记忆的成分分析来解释，前瞻记忆和回顾记忆既有相同之处，也有不同之处。
Younger and older subjects were asked to perform an action whenever target words occurred during a short-term memory task. The difficulty of this prospective memory task was manipulated by varying the delay preceding the occurrence of a target event and by varying the number of different target events. Age-related performance differences emerged when there were several different target events but not when there was one target event presented several times. Age-related performance differences, when they occurred, were associated with poorer retrospective memory for the target events. The results were interpreted in terms of a componential analvsis of prospective memory, which assumes both similarities and differences between prospective and retrospective memory.
