The results of a recent study, Félix et al., 2020, give new information about the behavioral and endocrine correlates of individual differences in the potential for androgen response in male cichlid fish. We think the study raises issues that are pertinent to the study of hormones and competition in other species, particularly humans. Focusing mostly on androgen reactivity to social challenge, we emphasize the importance of inter-individual variability in physiology, personality, and motivation in studies of hormone responses to social encounters. Additionally, we give special attention to matters of “repeatability” and the timing of hormone sampling. We conclude with an appreciation of the value of comparative analysis in behavioral endocrinology.

Félix 等人（2020 年）最近的一项研究结果提供了关于雄性慈鲷鱼雄激素反应潜力的个体差异的行为和内分泌相关性的新信息。我们认为这项研究提出了与其他物种（尤其是人类）的激素和竞争研究相关的问题。我们主要关注雄激素对社会挑战的反应，强调生理、个性和动机的个体差异在研究激素对社会遭遇的反应中的重要性。此外，我们特别注意“可重复性”和激素采样时间的问题。最后，我们对行为内分泌学中比较分析的价值表示赞赏。
