Wearable camera photo review has successfully been used to enhance memory, yet very little is known about the underlying mechanisms. Here, the sequential presentation of wearable camera photos - a key feature of wearable camera photo review - is examined using behavioural and EEG measures. Twelve female participants were taken on a walking tour, stopping at a series of predefined targets, while wearing a camera that captured photographs automatically. A sequence of four photos leading to these targets was selected (∼ 200 trials) and together with control photos, these were used in a recognition task one week later. Participants' recognition performance improved with the sequence of photos (measured in hit rates, correct rejections, & sensitivity), revealing for the first time, a positive effect of sequence of photos in wearable camera photo review. This has important implications for understanding the sequential and cumulative effects of cues on episodic remembering. An old-new ERP effect was also observed over visual regions for hits vs. correct rejections, highlighting the importance of visual processing not only for perception but also for the location of activated memory representations.
可穿戴相机照片回顾已成功用于增强记忆，但对其潜在机制知之甚少。在这里，使用行为和 EEG 测量来检查可穿戴相机照片回顾的关键特征——可穿戴相机照片的顺序呈现。12 名女性参与者进行了一次步行游览，在一系列预定的目标处停留，同时佩戴可自动拍摄照片的相机。选择了一系列通向这些目标的四张照片（约 200 次试验），并与对照照片一起，在一周后用于识别任务。参与者的识别表现随着照片序列的增加而提高（以击中率、正确拒绝率和敏感性衡量），这首次揭示了可穿戴相机照片回顾中照片序列的积极影响。这对于理解线索对情景记忆的顺序和累积影响具有重要意义。对于击中与正确拒绝，在视觉区域也观察到了新旧 ERP 效应，突出了视觉处理的重要性，不仅对于感知，而且对于激活的记忆表示的位置也是如此。
