我们关注的是项目重复，列表长度和项目的类别的影响，在老年人与年轻人相比，自由回忆。在实验1中，年轻人和老年人的样本回忆了27个单词和27个动作事件（由受试者执行的迷你任务）。有些项目介绍了一次，有些介绍了两次。虽然年轻的受试者在两种类型的列表上都表现出更好的回忆，但老年样本和年轻样本一样受益于项目重复。这一发现在实验2中得到了重复。实验2的第二个发现是，在长而不是短的单词和动作事件的回忆中，有显着的年龄效应。年龄×重复效应交互作用的缺失归因于重复操纵的强度性质。年龄效应在回忆的长名单被归因于可能的赤字检索熟练。
We were concerned with the effects of item repetition, list length, and class of item on free recall in elderly as compared with young adults. In Experiment 1, samples of young and elderly adults recalled a list of 27 words and a list of 27 action events (minitasks performed by the subjects). Some items were presented once and some twice. Although the younger subjects showed better recall on both types of lists, the older sample benefited from item repetition as much as did the younger sample. This finding was replicated in Experiment 2. A second finding in Experiment 2 was a significant aging effect in the recall of long but not of short lists of both words and action events. The absence of an Age× Repetition Effect interaction was ascribed to the strength nature of the repetition manipulation. The age effects in the recall of the long lists were attributed to possible deficits in retrieval proficiency.
