Case studies of memory-impaired individuals consistently show that reminiscing with SenseCam images enhances event recall. This exploratory study examined whether a similar benefit would occur for the consolidation of memories in memory-unimpaired people. We tested delayed recall for atypical actions observed on a lengthy walk. Participants used SenseCam, a diary, or no external memory aid while walking, followed by reminiscence with SenseCam images, diary entries, or no aid, either alone (self-reminiscence) or with the experimenter (social reminiscence). One week later, when tested without SenseCam images or diary entries, prior social reminiscence produced greater recall than self-reminiscence, but there were no differences between memory aid conditions for action free recall or action order recall. When methodological variables were controlled, there was no recall advantage for SenseCam reminiscence with memory-unimpaired participants. The case studies and present study differ in multiple ways, making direct comparisons problematic. SenseCam is a valuable aid to the memory impaired, but its mnemonic value for non-clinical populations remains to be determined.
记忆障碍个体的案例研究一致表明，使用 SenseCam 图像回忆会增强事件回忆。本探索性研究检验了在记忆正常的人群中，这种类似的益处是否会发生在记忆巩固上。我们测试了在一次长时间散步中观察到的异常行为的延迟回忆。参与者在散步时使用 SenseCam、日记或没有外部记忆辅助工具，然后单独使用 SenseCam 图像、日记条目或不使用辅助工具进行回忆（自我回忆）或与实验者一起回忆（社交回忆）。一周后，在没有 SenseCam 图像或日记条目的情况下进行测试时，先前的社交回忆比自我回忆产生更多的回忆，但在行为自由回忆或行为顺序回忆方面，记忆辅助条件之间没有差异。当控制了方法学变量时，对于记忆正常的参与者，使用 SenseCam 回忆并没有回忆优势。案例研究和本研究在多个方面存在差异，使得直接比较变得困难。对于记忆障碍者来说，SenseCam 是一种有价值的记忆辅助工具，但它对非临床人群的记忆价值仍有待确定。
