Abstract

Working memory (WM) has been a major focus of cognitive science and neuroscience for the past 50 years. While most WM research has centered on the mechanisms of objects, there has been a lack of investigation into the cognitive and neural mechanisms of events, which are the building blocks of our experience. Using confirmatory factor analysis, psychophysical experiments, and resting-state and task functional magnetic resonance imaging methods, our study demonstrated that events have an independent storage space within WM, named as event cache, with distinct neural correlates compared to object storage in WM. We found the cerebellar network to be the most essential network for event cache, with the left cerebellum Crus I being particularly involved in encoding and maintaining events. Our findings shed critical light on the neuropsychological mechanism of WM by revealing event cache as an independent component of WM and encourage the reconsideration of theoretical models for WM.

事件缓存：工作记忆中的一个独立组件

工作记忆（Working memory， WM）是近50年来认知科学和神经科学研究的热点。虽然大多数WM研究都集中在对象的机制上，但对事件的认知和神经机制的研究一直缺乏，而事件是我们经验的基石。通过验证性因子分析、心理物理实验以及静息状态和任务功能磁共振成像方法，我们的研究表明，与WM中的对象存储相比，事件在WM中具有独立的存储空间，称为事件缓存，具有不同的神经关联。我们发现小脑网络是事件缓存最重要的网络，其中左小脑小腿1特别参与编码和维护事件。我们的发现通过揭示事件缓存作为WM的一个独立组成部分，为WM的神经心理学机制提供了重要的线索，并鼓励重新考虑WM的理论模型。
