Memories for episodes are temporally structured. Cognitive models derived from list-learning experiments attribute this structure to the retrieval of temporal context information that indicates when a memory occurred. These models predict key features of memory recall, such as the strong tendency to retrieve studied items in the order in which they were first encountered. Can such models explain ecological memory behaviors, such as eye movements during encoding and retrieval of complex visual stimuli? We tested predictions from retrieved-context models using three data sets involving recognition memory and free viewing of complex scenes. Subjects reinstated sequences of eye movements from one scene-viewing episode to the next. Moreover, sequence reinstatement decayed over time and was associated with successful memory. We observed memory-driven reinstatement even after accounting for intrinsic scene properties that produced consistent eye movements. These findings confirm predictions of retrieved-context models, suggesting retrieval of temporal context influences complex behaviors generated during naturalistic memory experiences.

记忆片段是具有时间结构的。从列表学习实验中得出的认知模型将这种结构归因于检索时间上下文信息,该信息指示记忆何时发生。这些模型预测了记忆召回的关键特征,例如强烈倾向于按照首次遇到的顺序检索已学习的项目。这些模型能否解释生态记忆行为,例如在编码和检索复杂视觉刺激时的眼球运动?我们使用三个涉及复杂场景的识别记忆和自由观看的数据集来测试检索到的上下文模型的预测。受试者将一个场景观看事件中的眼球运动序列重新建立到下一个事件中。此外,序列重新建立会随着时间的推移而衰减,并且与成功的记忆相关。即使在考虑了产生一致眼球运动的内在场景属性之后,我们也观察到了记忆驱动的重新建立。这些发现证实了检索到的上下文模型的预测,表明检索到的时间上下文会影响在自然记忆体验中产生的复杂行为。(PsycInfo 数据库记录(c)2021 APA,保留所有权利)。
