项目摘要

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.

使用新的生活记录技术训练老年人的自传体记忆对亲身经历的过去事件的记忆，或情节记忆，是认知能力受损最严重的通过健康的衰老和第一个阿尔茨海默氏症的下降。因此，插曲也就不足为奇了在这些人群中，记忆一直是认知训练研究的主要目标。然而，这些研究中的大多数我关注的是对实验室刺激的情景记忆(如单词或图片的列表)，而不是情节记忆，就像它通常在现实世界中运行的那样--即自传体记忆。自传体记忆指的是对我们自己生活中的事件的记忆，比如我们上周末或早上我们把车停在那里。尽管人们通常认为使用Word或图片要迁移到日常记忆中，迁移往往很小，因为两者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更接近记忆在现实世界中的使用方式。因此，我们不是为了实验室刺激而训练记忆，而是建议训练自传体记忆。这种方法是新颖的，因为以往对老年人的记忆训练研究都没有集中在自传体记忆。造成这一研究差距的原因之一是，直到最近，它一直非常很难训练自传体记忆并准确衡量其改善程度。这种情况最近出现了由于创造了新的可穿戴技术，如生活记录摄像头，这一点发生了变化。这些摄像头可以以第一人称视角连续自动拍摄照片，无需用户干预。初步研究表明，记录生活的相机照片可以极大地增强人的记忆力赦免。这项拟议的研究将使用生活记录相机训练老年人的自传体记忆通过它们创建的照片和电影，这也将允许准确测量记忆改善。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)证明自传体记忆训练产生了对日常记忆测量的显著转移。(三)证明自传体记忆训练的效果持续了几个月。总之，拟议的研究将探索一种基于训练的创新记忆训练方法自传体记忆，而不是使用实验室刺激的传统训练方法。拿走利用新的生活日志技术，我们将使用参与者自己的记忆在健康的OAS中训练记忆记忆，这可能会增强日常生活中对记忆的转移。结果将为关键的试点提供未来R01应用程序的数据重点是使用我们的新方法在早期恢复情节记忆阿尔茨海默氏症。
