Objective:Forgetting names is a common memory concern for people with amnestic mild cognitive impairment (aMCI) and is related to explicit memory deficits and pathological changes in the medial temporal lobes at the early stages of Alzheimer’s disease (AD). In the current experiment, we tested a unique method to improve memory for face–name associations in people with aMCI involving incidental rehearsal of face–name pairs.Method:Older adults with aMCI and age- and education-matched controls learned 24 face–name pairs and were tested via immediate cued recall with faces as cues for associated names. During a 25- to 30-min retention interval, 10 of the face–name pairs reappeared as a quarter of the items on a seemingly unrelated 1-back task on faces, with the superimposed names irrelevant to the task. After the delay, surprise delayed cued recall and forced-choice associative recognition tests were administered for the face–name pairs.Results:Both groups showed reduced forgetting of the names that repeated as distraction and enhanced recollection of these pairs.Conclusions:The results demonstrate that passive methods to prompt automatic retrieval of associations may hold promise as interventions for people with early signs of AD.

一种改善遗忘型轻度认知障碍老年人面名记忆的附带学习方法

目的：忘记名字是遗忘型轻度认知障碍（aMCI）患者常见的记忆问题，与阿尔茨海默病（AD）早期的显性记忆缺陷和内侧颞叶的病理变化有关。在当前的实验中，我们测试了一种独特的方法来提高 aMCI 患者对人脸名称关联的记忆，包括偶然排练人脸名称对。方法：患有 aMCI 和年龄和教育匹配的对照的老年人学习了 24 个人脸名称对并进行了测试通过以面孔作为关联名称的线索的即时线索回忆。在 25 到 30 分钟的保留时间间隔内，10 个人脸-姓名对重新出现在看似无关的 1-back 人脸任务中的四分之一项目中，叠加的名称与任务无关。在延迟之后，对面孔-姓名对进行了意外延迟提示回忆和强制选择联想识别测试。结果：两组都显示出对重复的姓名的遗忘减少，并增强了这些对的回忆。结论：结果表明提示自动检索关联的被动方法可能有望作为具有早期 AD 迹象的人的干预措施。
