Older adults are substantially impaired in memory for specific past events, particularly for memory of contextual information, such as when an event happened (temporal-order memory). In the current study, we investigated a novel approach for training temporal-order memory in older adults using wearable cameras that automatically take first-person photos of participants' lives.
As opposed to the traditional method of training memory using simple laboratory stimuli (laboratory memory-LM), our method trained memory using participants' life events (autobiographical memory-AM). We randomly assigned participants to 3 groups, the AM group trained using photos from wearable cameras, the LM group trained using conventional laboratory stimuli (scene photos), and the control vocabulary knowledge group trained on word definitions. We assessed temporal-order memory for AM events (AM task) and LM stimuli (LM task) in the lab before and after training, which occurred at home 5 days per week for 4-5 weeks.
A significant interaction showed that AM training was more effective for enhancing AM whereas LM training was more effective in improving LM. The control training condition did not enhance either form of memory.
The results suggest that using photos from wearable cameras is a promising approach for improving AM in older adults.
老年人对特定过去事件的记忆存在显著损害,尤其是对情境信息的记忆,比如事件发生的时间(时间顺序记忆)。在本研究中,我们调查了一种使用可穿戴相机训练老年人时间顺序记忆的新方法,该相机能自动拍摄参与者生活中的第一人称照片。
与使用简单实验室刺激训练记忆的传统方法(实验室记忆-LM)不同,我们的方法使用参与者的生活事件训练记忆(自传体记忆-AM)。我们将参与者随机分为3组,AM组使用可穿戴相机拍摄的照片进行训练,LM组使用传统实验室刺激(场景照片)进行训练,控制组词汇知识组则进行单词定义训练。我们在训练前后在实验室评估了对AM事件(AM任务)和LM刺激(LM任务)的时间顺序记忆,训练在参与者家中每周进行5天,持续4至5周。
显著的交互作用表明,AM训练在增强AM方面更有效,而LM训练在改善LM方面更有效。控制训练条件对两种记忆形式均无增强作用。
结果表明,使用可穿戴相机拍摄的照片是改善老年人AM的一种有前景的方法。
