两项研究比较了年轻人和老年人在短暂间隔后对位置信息的记忆。实验1发现，个人位置的有意空间记忆的准确性是相似的，在年轻人和老年人的参与者设置大小为3和6。这两个小组还对与较大的位置配置相关的各个位置进行编码。实验2表明，与年轻人一样，老年人在字母工作记忆任务中对测试探针的反应潜伏期受到与任务无关的空间信息的负面影响。这种干扰效应表明老年人对空间信息的偶然记忆得以保留。总之，这些数据表明，初始编码的空间信息相对较少的项目在很大程度上保留在健康的老年人和空间信息的表征持续很短的时间间隔。
Two studies compared young and older adults' memory for location information after brief intervals. Experiment 1 found that accuracy of intentional spatial memory for individual locations was similar in young and older participants for set sizes of 3 and 6. Both groups also encoded individual locations in relation to the larger configuration of locations. Experiment 2 showed that like young adults, older adults' latency to respond to a test probe in a letter working memory task was negatively influenced by spatial information that was irrelevant to the task. This interference effect indicated preserved incidental memory for spatial information in older adults. Together, these data suggest that initial encoding of spatial information for relatively small numbers of items is largely preserved in healthy older adults and that representations of spatial information persist over short intervals.
