参与者听了两位发言者说的话，然后决定每个词是谁说的。作者对说话者的知觉独特性和参与者对单词进行的认知操作的独特性有所不同。与年轻人相比，当知觉或认知操作条件相似时，老年人的来源监控分数显著较低，但当两种线索中的任何一种更具区分性时，老年人的来源监控分数并不明显。组合线索不会影响对年轻人的来源监控，但会损害老年人相对于独特知觉条件的表现。显然，老年人产生认知线索是以编码知觉线索为代价的；任何绑定知觉和语义信息的缺陷，在来源监控方面都比在旧/新识别方面更不利。在评估老年人额叶功能和来源监测的神经心理测试之间没有相关性。
Participants heard words said by 2 speakers and later decided who said each word. The authors varied the perceptual distinctiveness of the speakers and the distinctiveness of the cognitive operations participants performed on the words. Relative to younger adults, older adults had significantly lower source monitoring scores when perceptual or cognitive operations conditions were similar but not when either cue was more distinctive. Combining cues did not affect source monitoring of younger adults but hurt older adults' performance relative to the distinctive perceptual condition. Evidently, older adults generate cognitive cues at the expense of encoding perceptual cues; any deficit in binding perceptual and semantic information disadvantages them more in source monitoring than in old/new recognition. There was no correlation between neuropsychological tests assessing frontal function and source monitoring in older adults.
