最近的研究表明，构成日常生活事件的连续信息流在情景记忆中被暂时压缩，但这种压缩机制的特征和决定因素尚不清楚。本研究使用结合可穿戴相机技术的实验范例来检验这个问题。参与者经历了一系列现实生活中的事件，然后被要求在脑海中重播在原始事件中拍摄的照片所提示的各种事件序列。对时间压缩（精神上重新体验事件所需的时间与实际事件持续时间之比）的估计表明，事件被重放的速度平均约为原始经历的8倍。这种压缩机制似乎是通过将事件表示为被时间不连续分隔的连续时刻或先前经验片段来运作的。然而，重要的是，时间压缩率不是恒定的，涉及目标导向行为的事件的时间压缩率更低。结果还表明，事件的感知持续时间随着先前经验回忆时刻的密度而增加。综上所述，这些数据扩展了我们对情景记忆中真实事件的时间压缩和感知持续时间的机制的理解。
Recent studies suggest that the continuous flow of information that constitutes daily life events is temporally compressed in episodic memory, yet the characteristics and determinants of this compression mechanism remain unclear. This study examined this question using an experimental paradigm incorporating wearable camera technology. Participants experienced a series of real-life events and were later asked to mentally replay various event sequences that were cued by pictures taken during the original events. Estimates of temporal compression (the ratio of the time needed to mentally re-experience an event to the actual event duration) showed that events were replayed, on average, about eight times faster than the original experiences. This compression mechanism seemed to operate by representing events as a succession of moments or slices of prior experience separated by temporal discontinuities. Importantly, however, rates of temporal compression were not constant and were lower for events involving goal-directed actions. The results also showed that the perceived duration of events increased with the density of recalled moments of prior experience. Taken together, these data extend our understanding of the mechanisms underlying the temporal compression and perceived duration of real-life events in episodic memory.
