老年人在联想记忆（相对于项目记忆）任务上的表现通常比年轻人差。对这种缺陷的一种解释是，老年人用于编码关联信息的注意力资源较少。以前的研究人员调查这一问题的注意力分散在编码，然后检查是否关联和项目识别受到不同的影响。在目前的研究中，我们使用了一个不同的认知任务，显示税收的注意力资源：基于事件的前瞻性记忆。虽然老年人表现出较差的关联，相对于项目，记忆，存在的前瞻性记忆任务在编码降低项目和关联记忆的准确性在两个年龄组相同的程度。这些结果不支持年龄相关的联想赤字的资源帐户。
Older adults typically perform worse than younger adults on tasks of associative, relative to item, memory. One account of this deficit is that older adults have fewer attentional resources to encode associative information. Previous researchers investigating this issue have divided attention at encoding and then have examined whether associative and item recognition were differentially affected. In the current study, we used a different cognitive task shown to tax attentional resources: event-based prospective memory. Although older adults demonstrated worse associative, relative to item, memory, the presence of the prospective memory task at encoding decreased item and associative memory accuracy to the same extent in both age groups. These results do not support the resource account of age-related associative deficits.
