摘要

利他行为可以受到包括荷尔蒙水平在内的多种因素的调节，但据报道，这些因素的影响仍然参差不齐。了解利他主义的近似机制有助于检验最终进化解释的预测。我们调查了睾酮和皮质醇的内源性唾液水平与独裁者游戏（DG）提议（作为利他主义的替代物）之间的关系。贝叶斯数据分析和模型比较显示，女性的睾酮和皮质醇与 DG 提议呈负相关，而男性的睾酮水平越高，其慷慨程度越高。这些结果表明，高睾酮可能会促进男性为追求地位而做出利他行为。

Generosity as a status signal: Higher-testosterone men exhibit greater altruism in the dictator game

Altruistic behavior can be modulated by many factors including hormonal levels, but their reported effects remain mixed. Understanding the proximate mechanisms of altruism such as these can help test predictions of ultimate, evolutionary explanations. We investigated the relationship of the endogenous salivary levels of testosterone and cortisol with Dictator Game (DG) offers as a proxy of altruism on a sample of general-population participants (N = 158, 84 F, 74 M). Bayesian data analysis and model comparison showed both testosterone and cortisol were negatively correlated with DG offers in women, while higher testosterone levels were associated with greater generosity in men. These results suggest that high testosterone may promote altruistic behavior in the service of status-seeking among men.

期刊介绍： Evolution and Human Behavior is an interdisciplinary journal, presenting research reports and theory in which evolutionary perspectives are brought to bear on the study of human behavior. It is primarily a scientific journal, but submissions from scholars in the humanities are also encouraged. Papers reporting on theoretical and empirical work on other species will be welcome if their relevance to the human animal is apparent.
