Children raised in chaotic households show affect dysregulation during later childhood. To understand why, we took day‐long home recordings using microphones and autonomic monitors from 74 12‐month‐old infant–caregiver dyads (40% male, 60% white, data collected between 2018 and 2021). Caregivers in low‐Confusion Hubbub And Order Scale (chaos) households responded to negative affect infant vocalizations by changing their own arousal and vocalizing in response; but high‐chaos caregivers did not, whereas infants in low‐chaos households consistently produced clusters of negative vocalizations around peaks in their own arousal, high‐chaos infants did not. Their negative vocalizations were less tied to their own underlying arousal. Our data indicate that, in chaotic households, both communicating and responding are atypical: infants are not expressing their levels of arousal, and caregivers are under‐responsive to their infants' behavioral signals.

需要大声喊叫才能被听到？来自混乱家庭的婴儿的照顾者反应性低下以及声音信号和自主神经唤醒之间的脱节


在混乱家庭中长大的孩子在童年后期表现出影响失调。为了了解原因，我们使用麦克风和自主神经监护仪对 74 名 12 个月大的婴儿照顾者二人组（40% 为男性，60% 为白人，2018 年至 2021 年间收集的数据）进行了为期一天的家庭录音。低混淆 Hubbub And Order Scale（混沌）家庭中的照顾者通过改变自己的唤醒和发声来回应对负面影响婴儿的发声;但是高混乱的照顾者没有，而低混乱家庭中的婴儿在他们自己的唤醒高峰周围持续产生一簇负面的声音，而高混乱的婴儿则没有。他们的消极发声与他们自己潜在的唤醒关系较小。我们的数据表明，在混乱的家庭中，沟通和回应都是非典型的：婴儿没有表达他们的唤醒水平，照顾者对婴儿的行为信号反应不足。
