在正常老年人和轻度阿尔茨海默病（AD）患者中检查了检索和监测事实信息的能力。对被试进行48道常识题的自由回忆和多项选择再认测验。在这两个测试中，受试者对他们的答案的确定性进行了信心评级，他们还对那些他们在回忆中没有回答的问题进行了感知评级。结果表明，控制的优势，病人在回忆，有点减少了认识。然而，没有组间差异的任何斜率有关的评级准确性：回忆和识别的信心评级的函数，并承认的问题没有回答的功能，在回忆的感觉知道。这种结果模式表明，早期AD与事实检索缺陷有关，尽管监测储存的一般知识的能力可能是完整的。
The ability to retrieve and monitor factual information was examined in normal old adults and patients with a mild Alzheimer's disease (AD). Subjects were given free recall and multiple-choice recognition tests of 48 general knowledge questions. For both tests, subjects made confidence ratings regarding the certainty of their answers, and they also made feeling-of-knowing ratings for those questions they did not answer in recall. Results indicated a superiority of controls over patients in recall that was somewhat reduced in recognition. However, there were no group differences in any of the slopes relating rating to accuracy: recall and recognition as a function of confidence rating, and recognition of questions not answered in recall as a function of feeling-of-knowing. This pattern of outcome indicates that early AD is associated with a deficit in fact-retrieval, although the ability to monitor stored general knowledge may be intact.
