三个实验测试了时间和项目记忆的年龄差异之间的关系是否取决于项目记忆测量依赖于上下文记忆的程度。作者预测，时间记忆与自由回忆的关系比与再认记忆的关系更强。结果表明，控制自由回忆后，时间记忆的年龄差异可以消除，但不能再认记忆性能。在某些条件下，再认记忆在时间记忆的年龄相关方差中占很大比例。这些结果挑战了过去的研究，这些研究将时间记忆和项目记忆的年龄差异解释为独立的，并表明背景记忆的普遍下降可能是老年人在所有类型的记忆测试中表现降低的基础。
Three experiments tested whether the relationship between age differences in temporal and item memory depends on the degree to which the item memory measure relies on memory for context. The authors predicted a stronger relationship of temporal memory to free recall than to recognition memory. Results showed that age differences in temporal memory could be eliminated after controlling for free recall but not recognition memory performance. Under some conditions recognition memory accounted for a significant portion of age-related variance in temporal memory. These results challenge past research that has interpreted age differences in temporal and item memory as independent and suggest that a generalized decline in context memory may underlie reduced performance in older adults on all types of memory tests.
