This case study describes the use of a wearable camera, SenseCam, which automatically captures several hundred images per day, to aid autobiographical memory in a patient, Mrs B, with severe memory impairment following limbic encephalitis. By using SenseCam to record personally experienced events we intended that SenseCam pictures would form a pictorial diary to cue and consolidate autobiographical memories. After wearing SenseCam, Mrs B plugged the camera into a PC which uploaded the recorded images and allowed them to be viewed at speed, like watching a movie. In the control condition, a written diary was used to record and remind her of autobiographical events. After viewing SenseCam images, Mrs B was able to recall approximately 80% of recent, personally experienced events. Retention of events was maintained in the long-term, 11 months afterwards, and without viewing SenseCam images for three months. After using the written diary, Mrs B was able to remember around 49% of an event; after one month with no diary readings she had no recall of the same events. We suggest that factors relating to rehearsal/re-consolidation may have enabled SenseCam images to improve Mrs B's autobiographical recollection.
本案例研究描述了可穿戴式相机SenseCam的使用情况，该相机每天能自动拍摄数百张图像，用于帮助边缘性脑炎后患有严重记忆障碍的患者B夫人增强自传体记忆。通过使用SenseCam记录个人经历的事件，我们希望SenseCam拍摄的图片能形成一本图像日记，以提示和巩固自传体记忆。B夫人佩戴SenseCam后，将相机插入电脑，电脑会上传录制的图像，并能像看电影一样快速浏览。在对照条件下，使用书面日记记录并提醒她自传体事件。查看SenseCam图像后，B夫人能够回忆起约80%近期亲身经历的事件。事件记忆在11个月后的长期内得以保持，且在三个月未查看SenseCam图像的情况下依然如此。使用书面日记后，B夫人能记住约49%的事件；在一个月没有阅读日记后，她对相同事件毫无记忆。我们认为，与复述/重新巩固相关的因素可能使SenseCam图像改善了B夫人的自传体回忆。
