A large body of evidence indicates that individual differences in baseline concentrations of testosterone (T) are only weakly correlated with human aggression. Importantly, T concentrations are not static, but rather fluctuate rapidly in the context of competitive interactions, suggesting that acute fluctuations in T may be more relevant for our understanding of the neuroendocrine mechanisms underlying variability in human aggression. In this paper, we provide an overview of the literature on T and human competition, with a primary focus on the role of competition-induced T dynamics in the modulation of human aggression. In addition, we discuss potential neural mechanisms underlying the effect of T dynamics on human aggression. Finally, we highlight several challenges for the field of social neuroendocrinology and discuss areas of research that may enhance our understanding of the complex bi-directional relationship between T and human social behavior.
大量证据表明，睾酮（T）基线浓度的个体差异与人类攻击性之间的相关性较弱。重要的是，T浓度并非一成不变，而是在竞争性互动的背景下迅速波动，这表明T的急性波动可能与我们理解人类攻击性变异性背后的神经内分泌机制更为相关。在本文中，我们概述了关于T与人类竞争的文献，主要关注竞争诱导的T动态变化在调节人类攻击性方面的作用。此外，我们讨论了T动态变化对人类攻击性影响的潜在神经机制。最后，我们强调了社会神经内分泌学领域的几个挑战，并讨论了可能增进我们对T与人类社会行为之间复杂双向关系理解的研究领域。
