年轻人的“记住”判断伴随着对一个项目的来源比“知道”判断更好的记忆。此外，记忆判断不仅与单个源特征的更好记忆有关，而且与多个源特征的边界记忆有关。然而，老年人，独立于他们的主观记忆经验，通常不太可能将源特征“绑定”到一个项目以及在记忆中彼此“绑定”（即，的关联赤字）。在两个实验中，我们测试了对感知源特征的记忆，独立或约束，是否也是老年人记忆反应的基础，或者他们的联想缺陷是否导致他们将反应建立在其他类型的信息上。结果表明，检索的感知源功能，单独或绑定，形成的基础上，年轻人，但不是老年人的记忆判断，即使当整体水平的记忆感知源是密切相等的（实验1），当注意力明确指向源信息编码（实验2）。
Younger adults' "remember" judgments are accompanied by better memory for the source of an item than "know" judgments. Furthermore, remember judgments are not merely associated with better memory for individual source features but also with bound memory for multiple source features. However, older adults, independent of their subjective memory experience, are generally less likely to "bind" source features to an item and to each other in memory (i.e., the associative deficit). In two experiments, we tested whether memory for perceptual source features, independently or bound, is also the basis for older adults' remember responses or if their associative deficit leads them to base their responses on other types of information. The results suggest that retrieval of perceptual source features, individually or bound, forms the basis for younger but not for older adults' remember judgments even when the overall level of memory for perceptual sources is closely equated (Experiment 1) and when attention is explicitly directed to the source information at encoding (Experiment 2).
