适应性行为要求生物体不仅了解哪些刺激倾向于共同发生（例如，刺激A是否与不愉快的刺激B共同发生），而且了解共同发生的刺激是如何相关的（例如，A是否启动或阻止B）。在一项预登记的研究中（N = 200名成年人），我们调查了睡眠是否会促进需要联合记忆的适应性评估选择，这些选择需要刺激共现和刺激关系的联合记忆。参与者了解了导致或预防积极或消极健康状况的假想药品，随后是评估选择和外显记忆的测量。经过12小时的记忆保持间隔（包括夜间睡眠或白天清醒），参与者第二次完成相同的测量。结果表明，睡眠增强了因果产品-条件关系对选择的影响（通过多项建模分析揭示），增强了对特定刺激共同出现的记忆（通过记忆保存分析揭示）。研究结果表明，睡眠通过离线记忆巩固来促进适应性评估选择。
Adaptive behavior requires that organisms learn not only which stimuli tend to co-occur (e.g., whether stimulus A co-occurs with unpleasant stimulus B) but also how co-occurring stimuli are related (e.g., whether A starts or stops B). In a preregistered study (N = 200 adults), we investigated whether sleep would promote adaptive evaluative choices requiring joint memories for stimulus co-occurrences and stimulus relations. Participants learned about hypothetical pharmaceutical products that either cause or prevent positive or negative health conditions, followed by measures of evaluative choices and explicit memory. After a 12-hr retention interval including either nocturnal sleep or daytime wake, participants completed the same measures a second time. Results showed that sleep strengthened the impact of causal product–condition relations on choices (revealed by multinomial modeling analyses) and enhanced memories for specific stimulus co-occurrences (revealed by memory preservation analyses). The findings suggest that sleep promotes adaptive evaluative choices via offline memory consolidation.
