This study measured the effect of a wearable camera, SenseCam, on older and younger adults' memories of recently experienced everyday events. Participants used SenseCam to prospectively sample events from a typical week, which they recalled two weeks later. Recall was cued by a self-generated title only (control condition), by the title and forward-order SenseCam images, or by the title and random-order SenseCam images. In the control condition, older and younger adults' memories were comparably episodic, but older adults recalled more semantic details. Both forward- and random-order SenseCam images were associated with increased episodic and semantic recall in both groups, and there was a small but significant effect of temporal order favouring the forward-order condition. These findings suggest that SenseCam is effective in supporting retrieval of memory for recent events, and the results of the temporal order manipulation also shed light on the mechanism of SenseCam's effect.
本研究测量了可穿戴式相机SenseCam对老年人和年轻人近期日常经历事件记忆的影响。参与者使用SenseCam前瞻性地从典型的一周中采集事件样本,两周后进行回忆。回忆仅由自我生成的标题(对照条件)、标题和按顺序排列的SenseCam图像,或标题和随机排列的SenseCam图像进行提示。在对照条件下,老年人和年轻人的记忆在情节性方面相当,但老年人回忆出更多语义细节。按顺序排列和随机排列的SenseCam图像均与两组中情节性和语义性回忆的增加相关,并且时间顺序存在微小但显著的影响,有利于按顺序排列的条件。这些发现表明,SenseCam在支持对近期事件的记忆检索方面是有效的,并且时间顺序操纵的结果也揭示了SenseCam效果的机制。
