Although testosterone is associated with aggression in the popular imagination, previous research on the links between testosterone and human aggression has been inconsistent. This inconsistency might be because testosterone's effects on aggression depend on other moderators. In a large adolescent sample ( N = 984, of whom 460 provided hair samples), we examined associations between aggression and salivary testosterone, hair testosterone, and hair cortisol. Callous-unemotional traits, parental monitoring, and peer environment were examined as potential moderators of hormone-behavior associations. Salivary testosterone was not associated with aggression. Hair testosterone significantly predicted increased aggression, particularly at low levels of hair cortisol (i.e., Testosterone × Cortisol interaction). This study is the first to examine the relationship between hair hormones and externalizing behaviors and adds to the growing literature that indicates that androgenic effects on human behavior are contingent on aspects of the broader endocrine environment-in particular, levels of cortisol.
尽管在大众想象中，睾丸激素与攻击性有关，但之前关于睾丸激素与人类攻击性之间联系的研究结果并不一致。这种不一致可能是因为睾丸激素对攻击性的影响取决于其他调节因素。在一个大型青少年样本中（N=984，其中 460 人提供了头发样本），我们研究了攻击性与唾液睾丸激素、头发睾丸激素和头发皮质醇之间的关系。我们还研究了冷酷无情特质、父母监督和同伴环境是否为激素-行为关联的潜在调节因素。唾液睾丸激素与攻击性无关。头发睾丸激素显著预测攻击性增加，特别是在头发皮质醇水平较低时（即睾丸激素×皮质醇相互作用）。这项研究首次检验了头发激素与外向性行为之间的关系，并补充了越来越多的文献，表明雄激素对人类行为的影响取决于更广泛的内分泌环境的各个方面，特别是皮质醇水平。
