Abstract

Story retelling is an important form of communication, cultural practice, and message transmission. Insufficient sleep is known to affect relevant cognitive skill areas necessary for story retelling or transmission fidelity. We conducted a preregistered randomized cross-over study on n = 155 young adults with exogenously assigned nightly sleep levels experienced in their at-home environments. A serial story reproduction task was administered online, and chains of up to three retells of a given story involved varied numbers of sleep restricted (SR) versus well-rested (WR) retellers. While story content decayed with each retell, group-level analysis showed that additional SR retellers in a chain was associated with greater decay, which mostly resulted from the introduction of an initial SR reteller at the first retell. Supporting the group-level effect, individual-level analysis confirmed that the number of details and the story's key event were significantly less preserved during a participant's SR treatment week. Exploratory analysis showed an attenuation of this effect in those reporting a higher level of affective response (interest or surprise) in the story. This suggests that emotional engagement can combat the deleterious effects of SR on successful story retelling, and perhaps on other types of content recollection.

睡眠不足对信息连续再现的影响。
故事复述是一种重要的交际、文化实践和信息传递形式。众所周知,睡眠不足会影响故事复述或传播保真度所必需的相关认知技能领域。我们进行了一项预先登记的随机交叉研究,研究对象为n = 155名年轻成年人,他们在家庭环境中经历了外源分配的夜间睡眠水平。研究人员在网上进行了一项连续的故事复述任务,并对一个给定的故事进行多达三次的复述,其中包括不同数量的睡眠受限(SR)和休息良好(WR)的复述者。虽然故事内容会随着每次复述而衰减,但群体层面的分析表明,链条中额外的SR复述者与更大的衰减相关,这主要是由于在第一次复述时引入了初始SR复述者。支持群体水平效应,个体水平分析证实,在参与者的SR治疗周期间,细节和故事关键事件的数量明显减少。探索性分析显示,在那些对故事表现出较高程度情感反应(兴趣或惊讶)的人身上,这种影响有所减弱。这表明,情感投入可以对抗SR对成功复述故事的有害影响,也许对其他类型的内容回忆也是如此。
