Memory for time is influenced by reconstructive processes, but the underlying mechanisms remain unclear. The present study investigated whether the effect of schematic prior knowledge on temporal memory for movie scenes, produced by the incomplete presentation (cut) of the movie at encoding, is modulated by cut position, retention interval, and task repetition. In a timeline positioning task, participants were asked to indicate when short video clips extracted from a previously encoded movie occurred on a horizontal timeline that represented the video duration. In line with previous findings, removing the final part of the movie resulted in a systematic underestimation of clips' position as a function of their proximity to the missing part. Further experiments demonstrate that the direction of this automatic effect depends on which part of the movie is deleted from the encoding session, consistent with the inferential structure of the schema, and does not depend on consolidation nor reconsolidation processes, at least within the present experimental conditions. We propose that the observed bias depends on the automatic influence of reconstructive processes on judgments about the time of occurrence, based on prior schematic knowledge.

时间记忆受重建过程的影响，但潜在机制仍不清楚。本研究调查了由电影在编码时的不完整呈现（剪辑）产生的示意性先验知识对电影场景时间记忆的影响是否受到剪辑位置、保留间隔和任务重复的调制。在时间轴定位任务中，要求参与者指出从先前编码的电影中提取的短视频剪辑何时出现在代表视频持续时间的水平时间轴上。与之前的发现一致，删除电影的最后部分会导致系统低估剪辑的位置，因为它们与缺失部分的接近程度。进一步的实验表明，这种自动效果的方向取决于电影的哪一部分从编码会话中删除，与模式的推理结构一致，并且不依赖于合并或重新合并过程，至少在目前的实验条件下. 我们提出，观察到的偏差取决于重建过程对基于先验示意图知识的判断发生时间的自动影响。
