目前的研究探讨了两种操作的影响，平等和扩大间隔检索时间表在年轻人和老年人。首先，我们研究了扩展类型（系统与非系统）在产生扩展检索益处方面的作用。其次，我们研究了在原始编码事件后立即检索尝试以最大限度地减少遗忘的影响。据预测，包括多个检索尝试与最小的干预间距（最好完成在一个非系统的检索时间表）将是必要的，以产生一个好处，扩大检索等间距检索老年人，但不是年轻人，由于年龄差异的工作记忆能力。从两个实验的结果表明，存在一个扩大超过相等的间隔检索的好处调制的程度，间隔条件最大限度地减少遗忘在早期检索尝试的间隔条件。正如预测的那样，这些情况在年轻人和老年人之间存在很大差异。特别是，在老年人的两个干预项目之间的早期检索尝试产生显着的遗忘率相比，一个干预项目，而年轻的成年人可以保持性能高达五个干预事件在可比的条件。讨论的重点是短期遗忘，工作记忆容量的年龄差异，以及遗忘率和间隔提取时间表之间的关系。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
The current study examined the effects of two manipulations on equal and expanded spaced retrieval schedules in young and older adults. First, we examined the role that the type of expansion (systematic vs. nonsystematic) has in producing a benefit of expanded retrieval. Second, we examined the influence of an immediate retrieval attempt to minimize forgetting after the original encoding event. It was predicted that including multiple retrieval attempts with minimal intervening spacing (best accomplished in a nonsystematic retrieval schedule) would be necessary to produce a benefit of expanded retrieval over equal spaced retrieval for older adults but not young adults due to age differences in working memory capacity. Results from two experiments revealed that the presence of an expanded over equal spaced retrieval benefit is modulated by the extent to which the spacing conditions minimize forgetting in the early retrieval attempts in the spaced conditions. As predicted, these conditions differ substantially across young and older adults. In particular, in older adults two intervening items between early retrieval attempts produce dramatic rates of forgetting compared to one intervening item, whereas younger adults can maintain performance up to five intervening events in comparable conditions. Discussion focuses on age differences in short term forgetting, working memory capacity, and the relation between forgetting rates and spaced retrieval schedules.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
