摘要

许多经历都会随着时间的推移而发生变化。通过对这些时间规律性的记忆,可以预测未来多步发生的事件。由于时间上可预测的事件会在数天、数周和数年内重复发生,因此我们必须保持并有可能改变时间结构记忆,以支持适应性行为。我们探索了个体如何建立持久的时间规律性模型来指导多步骤预测。健康的年轻成年人(实验 1:人数=99,年龄=18-40 岁;实验 2:人数=204,年龄=19-40 岁)学习了在类别水平上可预测并包含偶然感知细节的场景图像序列。然后,受试者会立即或延迟多步预测未来即将出现的场景类别。巩固提高了预测的效率,尤其是对更远未来事件的预测,但却减少了对感知特征的获取。此外,在巩固后保持基于链接的序列模型也提高了预测的准确性。因此,巩固可以促进高效持久的时间结构模型,从而促进对未来事件的预测。

Consolidation Enhances Sequential Multistep Anticipation but Diminishes Access to Perceptual Features.

Many experiences unfold predictably over time. Memory for these temporal regularities enables anticipation of events multiple steps into the future. Because temporally predictable events repeat over days, weeks, and years, we must maintain-and potentially transform-memories of temporal structure to support adaptive behavior. We explored how individuals build durable models of temporal regularities to guide multistep anticipation. Healthy young adults (Experiment 1: N = 99, age range = 18-40 years; Experiment 2: N = 204, age range = 19-40 years) learned sequences of scene images that were predictable at the category level and contained incidental perceptual details. Individuals then anticipated upcoming scene categories multiple steps into the future, immediately and at a delay. Consolidation increased the efficiency of anticipation, particularly for events further in the future, but diminished access to perceptual features. Further, maintaining a link-based model of the sequence after consolidation improved anticipation accuracy. Consolidation may therefore promote efficient and durable models of temporal structure, thus facilitating anticipation of future events.
