According to Gilead and colleagues, to be efficient abstraction requires a hierarchical organization of information into long-term memory. But, how and when are abstract representations consolidated into long-term memory and how are they integrated with pre-existing abstracta are questions not discussed by Gilead and colleagues. Here, we propose that these processes occur preferentially during offline periods such as sleep.

睡眠在抽象心理表征的形成和更新中的作用

根据 Gilead 及其同事的说法，有效的抽象需要将信息分层组织成长期记忆。但是，如何以及何时将抽象表示合并到长期记忆中，以及它们如何与预先存在的抽象集成是 Gilead 及其同事没有讨论的问题。在这里，我们建议这些过程优先发生在离线期间，例如睡眠。
