对于未来使用最突出和最重要的信息优先通过睡眠期间的主动处理来保存。情绪显著性是一种生物适应性线索，通过杏仁核和海马活动之间的相互作用影响情景记忆加工。然而，影响信息重要性的其他线索，如记住或忘记的明确方向，与信息的内在显着性相互作用，以决定其在记忆中的命运。目前尚不清楚睡眠过程如何选择性地整合这些复杂的信息。目前的研究检查了情绪和中性信息的记忆发展，这些信息在白天的时间内被提示要记住（TBR）或要忘记（TBF），包括午睡或清醒。基线记忆显示TBR线索的主导地位，无论情绪的显着性。正如预期的那样，午睡被发现比保持清醒更能保持记忆。此外，我们观察到一个趋势的相互作用表明，午睡特别增强了最显着的信息（负TBR项目）之间的歧视，其他信息。我们发现，负项目的记忆与午睡期间获得的SWS百分比呈正相关。此外，负TBR项目和负TBF项目之间的记忆差异的幅度随着睡眠纺锤波活动的增加而增加。综上所述，我们的研究结果表明，尽管主动记忆或有意遗忘的线索最初胜出，但睡眠期间的主动过程促进了显着性线索之间的竞争，以促进记忆中最显着的信息。
Information that is the most salient and important for future use is preferentially preserved through active processing during sleep. Emotional salience is a biologically adaptive cue that influences episodic memory processing through interactions between amygdalar and hippocampal activity. However, other cues that influence the importance of information, such as the explicit direction to remember or forget, interact with the inherent salience of information to determine its fate in memory. It is unknown how sleep-based processes selectively consolidate this complex information. The current study examined the development of memory for emotional and neutral information that was either cued to-be-remembered (TBR) or to-be-forgotten (TBF) across a daytime period including either napping or wakefulness. Baseline memory revealed dominance of the TBR cue, regardless of emotional salience. As anticipated, napping was found to preserve memory overall significantly better than remaining awake. Furthermore, we observed a trending interaction indicating that napping specifically enhanced the discrimination between the most salient information (negative TBR items) over other information. We found that memory for negative items was positively associated with the percentage of SWS obtained during a nap. Furthermore, the magnitude of the difference in memory between negative TBR items and negative TBF items increased with greater sleep spindle activity. Taken together, our results suggest that although the cue to actively remember or intentionally forget initially wins out, active processes during sleep facilitate the competition between salience cues to promote the most salient information in memory.
