Training Autobiographical Memory Retrieval in Healthy Older Adults Using Novel Lifelogging Technology

使用新的生活日志技术训练老年人的自传体记忆 个人经历的过去事件的记忆，或情景记忆，是最受损的认知能力 是第一个在老年痴呆症中下降的人。因此，这并不奇怪， 记忆是这些人群中认知训练研究的主要目标。然而，大多数研究 我专注于实验室刺激的情景记忆（如单词或图片列表），而不是 情景记忆，因为它通常在真实的世界中运作，即自传体记忆。 自传体记忆指的是我们对自己生活中事件的记忆，比如我们上周末做了什么， 我们早上把车停在哪了尽管人们通常认为，使用单词或 图片应该转移到日常记忆中，转移往往是因为小之间的差异很大 这些记忆任务。解决这个重要问题的一种方法是训练记忆能力， 记忆在真实的世界中的应用方式。因此，我们建议， 训练自传体记忆。 这种方法是新颖的，因为以前没有针对老年人的记忆训练研究。 自传体记忆研究中出现这种差距的原因之一是，直到最近， 自传体记忆的训练和准确测量其改善是困难的。这种情况最近 由于生活记录摄像头等新型可穿戴技术的出现，这些相机可以 连续自动地从第一人称视角拍摄照片，无需用户干预。 初步研究表明，生活记录相机照片可以显着提高记忆力， 健忘症拟议中的研究将使用生活记录相机训练老年人的自传体记忆 照片和电影从他们创建，这也将允许记忆改善的准确措施。 我们有三个具体目标。(1)证明自传体记忆训练产生迁移到 基于软件的未经训练的自传体记忆和实验室记忆任务。(2)表明 自传体记忆训练对日常记忆测量产生显著的转移。(3)证明 自传体记忆训练效果持续数月。 总之，本研究将探索一种基于训练的创新性记忆训练方法 自传体记忆，而不是传统的训练方法，使用实验室刺激。以 利用新的生活记录技术，我们将利用参与者自己的记忆训练健康OAs的记忆。 记忆，这可能会增强日常生活中的记忆转移。结果将提供关键的试点 未来R01应用的数据集中在使用我们的新方法来恢复早期的情景记忆。 老年痴呆症

Training autobiographical memory in older adults using novel lifelogging technology Memory for personally experienced past events, or episodic memory, is the cognitive ability most impaired by healthy aging and the first one to decline in Alzheimer's Disease. Therefore, it is not surprising that episodic memory has been a primary target of cognitive training studies in these populations. Yet, most of these studies have focused on episodic memory for laboratory stimuli (such as lists of words or pictures), rather than on episodic memory as it typically operates in the real world—namely autobiographical memory. Autobiographical memory refers to memory of events in our own life, such as what we did last weekend or where we parked the car in the morning. Although it is usually assumed that training memory using word or pictures should transfer to everyday memory, transfer is often small because of the large differences between these memory tasks. One way to address this important issue is to train memory abilities that are closer to the way memory is used in the real world. Thus, instead of training memory for laboratory stimuli, we propose to train autobiographical memory. This approach is novel as no previous memory training study in older adults has focused on autobiographical memory. One of the reasons for this gap in research is that, until recently, it has been very difficult to train autobiographical memory and accurately measure its improvement. This situation has recently changed due to the creation of novel wearable technology such as lifelogging cameras. These cameras can continuously and automatically take photos from a first-person perspective without user intervention. Preliminary studies have shown that lifelogging camera photos can dramatically enhance remembering in amnesics. The proposed studies will train autobiographical memory in older adults using lifelogging camera photos and movies created from them, which will also allow accurate measures of memory improvement. We have three specific aims. (1) Demonstrate that autobiographical memory training yields transfer to software-based untrained autobiographical memory and laboratory memory tasks. (2) Show that autobiographical memory training yields significant transfer to everyday memory measures. (3) Prove that autobiographical memory training effects persist for several months. In sum, the proposed study will investigate an innovative memory training approach based on training autobiographical memory instead of the traditional approach of training that uses laboratory stimuli. Taking advantage of novel lifelogging technology, we will train memory in healthy OAs using participants' own memories, which is likely to enhance transfer to memory in everyday life. The results will provide critical pilot data for a future R01 application focused on using our novel approach to rehabilitate episodic memory in early Alzheimer's Disease.
