Risk-taking propensity is a general personality disposition that has been studied using survey, behavioral, and cognitive modeling approaches, but the consistency and informativeness of the data across these approaches is rarely compared. To address this issue, we compared three behavioral tasks (BART, C-ART, and S-ART) designed to measure risk-taking propensity by correlating measures from both the behavioral and modeling approaches with responses on scales assumed to relate to risk-taking (impulsivity, sensation seeking, and drug abuse), and risk aversion (OCD symptoms and hoarding behavior). Results show that both the behavioral measure and the model parameter in the C-ART and the S-ART positively correlated with impulsivity and sensation seeking, with the behavioral measure showing a slight advantage. We also found discrepancies between the behavioral measure and the model parameter: the behavioral measures in the BART and the S-ART negatively correlated with hoarding behavior, whereas the model parameter positively correlated with impulsivity and OCD symptoms. Our findings indicate that these tasks, all of which claim to measure risk-taking propensity, vary in their abilities to measure different aspects of risk-taking propensity. Current computational models do not yet suffice as an additional index of risk-taking propensity.

评估风险承担倾向三项任务的有效性

冒险倾向是一种普遍的人格倾向,已经使用调查、行为和认知建模方法进行了研究,但很少比较这些方法中数据的一致性和信息量。为了解决这个问题,我们比较了旨在衡量冒险倾向的三个行为任务(BART、C-ART 和 S-ART) (冲动、寻求感觉和药物滥用)和风险规避(强迫症症状和囤积行为)。结果表明,C-ART和S-ART中的行为测量和模型参数均与冲动性和感觉寻求呈正相关,行为测量略有优势。我们还发现行为测量与模型参数之间存在差异:BART 和 S-ART 中的行为测量与囤积行为呈负相关,而模型参数与冲动和强迫症症状呈正相关。我们的研究结果表明,这些任务都声称可以衡量冒险倾向,但它们衡量冒险倾向不同方面的能力各不相同。当前的计算模型还不足以作为冒险倾向的额外指标。他们衡量冒险倾向不同方面的能力各不相同。当前的计算模型还不足以作为冒险倾向的额外指标。他们衡量冒险倾向不同方面的能力各不相同。当前的计算模型还不足以作为冒险倾向的额外指标。
