There has been strong interest, spanning several disciplines, in understanding adolescence as a developmental period of increased risk-taking behavior. Our goals focus on one line of investigation within this larger developmental risk framework. Specifically, we examined levels of pubertal hormones in girls in relation to their willingness to take greater financial risks to gain social status. To this end, we tested the hypothesis that higher levels of testosterone during the ages of pubertal maturation are associated with a greater willingness to sacrifice money for social admiration. Sixty-three girls ages 10-14 (M=12.74) participated in laboratory measures and completed at-home saliva sample collection. The Pubertal Development Scale (PDS) and basal hormone levels (testosterone, estradiol, DHEA) measured pubertal maturation. We made use of a developmentally appropriate version of an Auction Task in which adolescents could take financial risks in order to gain socially motivated outcomes (social status). PDS and testosterone were each associated with overall levels of financial risk taking over the course of the Auction Task. In hierarchical models, PDS and testosterone were predictors of the slope of overbidding over the course of the task. Results provide evidence for the role of testosterone and pubertal maturation in girls' motivations to engage in costly decision making in order to gain social status. Findings contribute to our understanding of the developmental underpinnings of some interesting aspects of adolescent risk behavior.
跨越多个学科，人们一直对将青春期理解为冒险行为增加的发育阶段有着浓厚兴趣。我们的目标聚焦于这个更大的发育风险框架内的一条研究路线。具体而言，我们研究了女孩青春期激素水平与她们为获得社会地位而承担更大经济风险的意愿之间的关系。为此，我们检验了这样一个假设：青春期成熟阶段较高的睾酮水平与为了社会赞赏而牺牲金钱的更大意愿相关。63名年龄在10至14岁（平均年龄12.74岁）的女孩参与了实验室测量，并完成了在家采集唾液样本的工作。青春期发育量表（PDS）和基础激素水平（睾酮、雌二醇、脱氢表雄酮）用于测量青春期成熟程度。我们采用了一个适合该年龄段的拍卖任务版本，在这个任务中，青少年可以承担经济风险以获得社会动机驱动的结果（社会地位）。在拍卖任务过程中，PDS和睾酮均与总体经济冒险水平相关。在分层模型中，PDS和睾酮是任务过程中出价过高斜率的预测因素。研究结果为睾酮和青春期成熟在女孩为获得社会地位而进行代价高昂的决策动机中的作用提供了证据。这些发现有助于我们理解青少年风险行为一些有趣方面的发育基础。
