许多人类行为，从交配到获取食物和攻击性，都伴随着一定程度的风险。睾酮是一种类固醇激素，已被认为与男性的一系列此类行为有关。然而，人们对睾丸激素和风险偏好之间的具体关系知之甚少。在这篇文章中，我们探讨了产前和青春期睾酮暴露、当前睾酮水平和男性经济风险偏好之间的关系。通过对98名男性的抽样调查，我们发现，在具有实际金钱回报潜力的投资游戏中，冒险行为与唾液睾酮水平和面部男子气概呈正相关，后者是青春期激素暴露的替代指标。2D：4D已被建议作为产前激素暴露的替代指标，但与风险偏好没有显著相关性。虽然这是一项关于关联性的研究，但其结果可能有助于揭示风险偏好的生物学决定因素。(C)2008 Elsevier Inc.保留所有权利。
Many human behaviors, from mating to food acquisition and aggressiveness, entail some degree of risk. Testosterone, a steroid hormone, has been implicated in a wide range of such behaviors in men. However, little is known about the specific relationship between testosterone and risk preferences. In this article, we explore the relationship between prenatal and pubertal testosterone exposure, current testosterone, and financial risk preferences in men. Using a sample of 98 men, we find that risk-taking in an investment game with potential for real monetary payoffs correlates positively with salivary testosterone levels and facial masculinity, with the latter being a proxy of pubertal hormone exposure. 2D:4D, which has been proposed as a proxy for prenatal hormone exposure, did not correlate significantly with risk preferences. Although this is a study of association, the results may shed light on biological determinants of risk preferences. (C) 2008 Elsevier Inc. All rights reserved.
