The association between testosterone and economic risk is not well-understood and is understudied. The present study aimed to further characterize what if any relationship testosterone has with risky economic decisions. To do so, 154 participants (78 men) completed the Iowa Gambling Task (IGT) (Bechara et al., 1994) and also provided saliva samples, which were assayed for endogenous testosterone levels using radioimmunoassay. High-levels of endogenous testosterone were associated with choosing less frequently from advantageous IGT decks of cards, indicating greater risk taking. The data showed that the effects of testosterone on IGT performance were similar for men and women. High-testosterone women and high-testosterone men made riskier choices than their low-testosterone counterparts of the same sex, and this effect was pronounced in women. Thus, high levels of testosterone are associated with willingness to incur greater risk in both sexes.
睾酮与经济风险之间的关系尚未得到充分理解，相关研究也较少。本研究旨在进一步探讨睾酮与风险经济决策之间的关系。为此，154 名参与者（78 名男性）完成了爱荷华赌博任务（IGT）（Bechara 等人，1994），并提供了唾液样本，使用放射免疫测定法测定了内源性睾酮水平。高水平的内源性睾酮与从有利的 IGT 牌组中选择的频率较低有关，表明风险更高。数据表明，睾酮对 IGT 表现的影响在男性和女性中相似。高睾酮女性和高睾酮男性比同性别的低睾酮个体做出了更冒险的选择，而这种影响在女性中更为明显。因此，高水平的睾酮与两性都愿意承担更大的风险有关。
