幼儿期是睡眠和情绪处理发生巨大变化的时期，也是首次发现这两个领域出现障碍的时期。虽然睡眠被认为是情绪处理和精神病理学的中心，但绝大多数实验数据都是在成年人中收集的。我们研究了急性睡眠限制（午睡剥夺）对幼儿情绪表达的影响。10名健康儿童（7名女性; 30-36个月）遵循严格的睡眠时间表（≥12.5小时的床上时间/24小时），在午睡和无午睡条件下进行两次随机分配的下午情绪评估之前（导致11天的方案），持续5天。孩子们观看了引发情感的图片（5张积极的、3张中性的、3张消极的）并完成了谜题（1张可解的、1张不可解的）。孩子们的脸被录像下来，情绪表现被编码。当睡眠受到限制时，儿童对中性图片的反应表现出较少的困惑，对中性和消极图片的反应表现出更多的消极，对积极图片的反应表现出较少的积极。睡眠限制还导致积极情绪反应（可解决的难题）减少34%，消极情绪反应增加31%，困惑反应（不可解决的难题）减少39%。这些发现表明，睡眠是幼儿如何应对世界的关键因素。当睡眠受到限制时，幼儿既不能充分利用积极的经验，也不能适应具有挑战性的环境。如果睡眠不足持续“征税”幼儿的情绪反应，他们可能无法有效地管理情绪调节的挑战，可能会使他们面临未来情绪/行为问题的风险。
Early childhood is a period of dramatic change in sleep and emotion processing, as well as a time when disturbance in both domains are first detected. Although sleep is recognized as central in emotion processing and psychopathology, the great majority of experimental data have been collected in adults. We examined the effects of acute sleep restriction (nap deprivation) on toddlers’ emotion expression. Ten healthy children (7 females; 30–36 months) followed a strict sleep schedule (≥12.5 hrs time in bed/24 hrs) for 5 days before each of two randomly-assigned afternoon emotion assessments following Nap and No-Nap conditions (resulting in an 11-day protocol). Children viewed emotion-eliciting pictures (5 positive, 3 neutral, 3 negative) and completed puzzles (1 solvable, 1 unsolvable). Children’s faces were video-recorded, and emotion displays were coded. When sleep restricted, children displayed less confusion in response to neutral pictures, more negativity to neutral and negative pictures, and less positivity to positive pictures. Sleep restriction also resulted in a 34% reduction in positive emotion responses (solvable puzzle), as well as a 31% increase in negative emotion responses and a 39% decrease in confused responses (unsolvable puzzle). These findings suggest sleep is a key factor in how young children respond to their world. When sleep restricted, toddlers are neither able to take full advantage of positive experiences nor are they as adaptive in challenging contexts. If insufficient sleep consistently “taxes” young children’s emotion responses, they may not manage emotion regulation challenges effectively, potentially placing them at risk for future emotional/behavioral problems.
