SYNOPSIS

Zeifman et al. present a study of fathers’ and non-fathers’ caregiving in response to infant crying. The associations among testosterone, amount of crying, and parental status were evaluated in a laboratory paradigm using a realistic infant simulator. Although fathers did not show lower levels of testosterone, men who listened to greater amounts of crying showed significant increases in testosterone, and men who increased in testosterone had less optimal caregiving. Hormonal influences on parental behavior, which have been studied extensively in non-human animals, are now being explicated in humans. Zeifman et al. help advance this area of research.

概要

Zeifman等。进行了一项针对婴儿哭泣的父亲和非父亲照料的研究。睾丸激素，哭泣量和父母身份之间的关联是在实验室范式中使用逼真的婴儿模拟器进行评估的。尽管父亲的睾丸激素水平没有降低，但是听更多哭声的男性睾丸激素水平显着增加，而睾丸激素水平升高的男性的最佳照护则较差。激素对父母行为的影响已在非人类动物中得到了广泛研究，现在在人类中已得到阐明。Zeifman等。帮助推进这一领域的研究。
