The risk-taking behavior is largely modulated by the subject's history, its lifestyles, by the characteristics of the situations with which it is compared, and also by the effects of prenatal androgens. Thus, the personality of the single person is a significant predictor of such way of acting.
The present study aimed to explore the relationship between Digit Ratio Measurement (2D:4D) and personality factors capable to be good predictors for choosing highly risky activities, such as caving. Furthermore, our purpose was to investigate whether 2D:4D ratio is related to cavers' affective states and to assess the personological and emotional features of 34 healthy cavers, aged between 24 and 71 years ( = 39.70, = 9.81).
Data analysis showed several significant correlations between 2D:4D and Deliberate Risk Taking (RTI) and Precautionary Behavior (RTI), confirming that 2D:4D is a reliable index able to predict risk-taking behaviors. Furthermore, data analysis showed that Conscientiousness and its sub-dimension (BFQ-2) are recurrent among significant correlations; in particular, the latter reports negative correlations with many factors of POMS. Moreover, all participants seemed to have a good attitude to collaboration, in terms of goal-direct strategy, and an adequate management of negative affective states, useful to maintaining a good level of stress within the group. Finally, the BFQ-2 factor seemed to be a predominant feature in the cavers, and this feature could be considered as predictive in the choice of an activity, such as caving, which requires curiosity, perseverance and a great planning of cave exploration.
冒险行为很大程度上受个体经历、生活方式、所比较情境的特征以及产前雄激素的影响所调节。因此，个体的性格是这种行为方式的一个重要预测指标。
本研究旨在探讨指长比测量（2D:4D）与能够很好预测选择高风险活动（如洞穴探险）的人格因素之间的关系。此外，我们的目的是调查2D:4D比例是否与洞穴探险者的情感状态相关，并评估34名年龄在24至71岁之间（平均年龄=39.70，标准差=9.81）的健康洞穴探险者的人格和情感特征。
数据分析显示2D:4D与蓄意冒险（RTI）和预防行为（RTI）之间存在若干显著相关性，证实2D:4D是能够预测冒险行为的可靠指标。此外，数据分析表明尽责性及其子维度（BFQ-2）在显著相关性中反复出现；特别是，后者与POMS的许多因素呈负相关。此外，就目标导向策略而言，所有参与者似乎都有良好的合作态度，并且能够适当管理负面情绪状态，这有助于在团队中保持良好的压力水平。最后，BFQ-2因子似乎是洞穴探险者的一个主要特征，并且这个特征可以被认为是预测选择诸如洞穴探险这样需要好奇心、毅力和大量洞穴探索计划的活动的一个因素。
