Optimal performance lies at intermediate autonomic arousal, but no previous research has examined whether the emergence of endogenous control associates with changes in children's up-regulation from hypo-arousal, as well as down-regulation from hyper-arousal. We used wearables to take day-long recordings from N = 58, 12-month-olds (60% white/58% female); and, in the same infants, we measured self-regulation in the lab with a still-face paradigm. Overall, our findings suggest that infants who showed more self-regulatory behaviors in the lab were more likely to actively change their behaviors in home settings moment-by-moment “on the fly” following changes in autonomic arousal, and that these changes result in up- as well as down-regulation. Implications for the role of atypical self-regulation in later psychopathology are discussed.

了解失变：生命早期的自我调节涉及唤醒的上调和下调


最佳性能在于中间自主神经唤醒，但以前的研究没有检查内源性控制的出现是否与儿童从低唤醒上调以及从过度唤醒下调的变化有关。我们使用可穿戴设备对 N = 58 岁、12 个月大的孩子（60% 白人/58% 女性）进行为期一天的记录;而且，在相同的婴儿中，我们在实验室中使用静止面孔范式测量了自我调节。总体而言，我们的研究结果表明，在实验室中表现出更多自我调节行为的婴儿更有可能在自主神经唤醒发生变化后每时每刻“即时”主动改变他们在家庭环境中的行为，并且这些变化会导致上调和下调。讨论了非典型自我调节在以后精神病理学中的作用的意义。
