While age differences in episodic memory are well documented, the impact of age on the structure of memories for real-world events has not been investigated in detail. Recent research has shown that the continuous flow of information that constitutes daily life events is compressed in episodic memory, such that the time needed to mentally replay an event is shorter than the actual event duration. To examine whether this process of temporal compression of prior experience in episodic memory is affected by aging, we asked young and older adults to engage in a series of events that simulated daily life activities while their experience was automatically recorded using a wearable camera. Subsequently, participants were asked to mentally replay these events in as much detail as possible and then to verbally report recalled contents and to rate the subjective qualities of their memories. Results revealed that the rates of temporal compression of events during mental replay were similar in young and older adults. In both age groups, rates of temporal compression were predicted by the density of recalled moments of prior experience per unit of time of the actual event duration. Interestingly, however, the number of recalled moments predicted the subjective vividness of memories in young but not in older adults. Taken together, these results suggest that the process of temporal compression of events in episodic memory is unaffected by age but that the subjective experience of memory vividness becomes less tied to recalled moments that represent the unfolding of events.

年龄对情景记忆中日常生活事件的时间压缩的影响。

尽管情节性记忆的年龄差异已得到充分证明，但对于现实事件中年龄对记忆结构的影响尚未进行详细调查。最近的研究表明，构成日常生活事件的信息的连续流在情节性记忆中受到压缩，因此，心理重放事件所需的时间比实际事件的持续时间短。为了检查这种在先例记忆中经历的时间压缩过程是否受到衰老的影响，我们要求年轻人和老年人进行一系列模拟日常生活活动的事件，同时使用可穿戴式相机自动记录他们的经历。后来，要求参与者在心理上尽可能多地重放这些事件，然后口头报告回忆的内容并评价他们记忆的主观素质。结果显示，在心理重播期间事件的时间压缩率在年轻人和老年人中相似。在这两个年龄组中，通过实际事件持续时间的每单位时间的先前经验的回忆时刻的密度来预测时间压缩的速率。然而，有趣的是，回忆的时刻数量预示着年轻人的记忆的主观生动，而不是老年人的记忆。在一起 这些结果表明，情节性记忆中事件的时间压缩过程不受年龄的影响，但是记忆生动性的主观体验与代表事件发生的回忆时刻之间的联系越来越少。（PsycINFO数据库记录（c）2020 APA，保留所有权利）。
