Antisocial behavior is costly and harmful to families, communities, and society. With roots in early childhood, antisocial behavior puts children at risk for poor physical and mental health outcomes across development. Callous–unemotional (CU) traits identify a subgroup of youth with particularly severe and stable antisocial behavior. Although much literature has examined CU traits in late childhood and adolescence, researchers are beginning to elucidate the developmental origins of CU traits. In this article, we review research examining the measurement and correlates of CU behaviors in early childhood, along with evidence that these early behaviors predict later measures of CU traits. We then describe research highlighting the role that parents play in the development of CU behaviors in early childhood. Finally, we outline translational implications and ethical considerations for studying CU behaviors and consider the use of the term CU traits in young children.

儿童早期的无情情绪行为：测量，意义和育儿的影响。

反社会行为代价高昂，对家庭，社区和社会有害。反社会行为源于儿童早期，使儿童在整个发展过程中面临身心健康状况不佳的风险。ous性情绪低落（CU）特征表明年轻人的亚群具有特别严重和稳定的反社会行为。尽管许多文献在儿童晚期和青春期检查了CU的性状，但研究人员开始阐明CU性状的发展起源。在本文中，我们回顾了研究对儿童早期CU行为的测量和相关性的研究，以及这些早期行为预测了CU特质的后续测量的证据。然后，我们描述了研究，突出了父母在幼儿期CU行为发展中所扮演的角色。最后，幼儿的铜特征。
