Awake quiescence immediately after encoding is conducive to episodic memory consolidation. Retrieval can render episodic memories labile again, but reconsolidation can modify and restrengthen them. It remained unknown whether awake quiescence after retrieval supports episodic memory reconsolidation. We sought to examine this question via an object-location memory paradigm. We failed to probe the effect of quiescence on reconsolidation, but we did observe an unforeseen "delayed" effect of quiescence on consolidation. Our findings reveal that the beneficial effect of quiescence on episodic memory consolidation is not restricted to immediately following encoding but can be achieved at a delayed stage and even following a period of task engagement.
清醒的安静状态立即在编码之后有利于情景记忆的巩固。检索可以使情景记忆再次不稳定,但再巩固可以修饰和加强它们。检索后清醒的安静状态是否支持情景记忆再巩固仍不清楚。我们通过物体-位置记忆范式来研究这个问题。我们未能探测到安静对再巩固的影响,但我们确实观察到安静对巩固的意外的“延迟”影响。我们的发现表明,安静对情景记忆巩固的有益影响不仅限于编码后立即发生,还可以在延迟阶段甚至在任务参与期间实现。
