Recent models on decision making under risk conditions have suggested that numerical abilities are important ingredients of advantageous decision-making performance, but empirical evidence is still limited. The results of our first study show that logical reasoning and basic mental calculation capacities predict ratio processing and that ratio processing predicts decision making under risk. In the second study, logical reasoning together with executive functions predicted probability processing (numeracy and probability knowledge), and probability processing predicted decision making under risk. These findings suggest that increasing an individual's understanding of ratios and probabilities should lead to more advantageous decisions under risk conditions.
近期关于风险条件下决策的模型表明，数字能力是有利决策表现的重要因素，但实证证据仍然有限。我们第一项研究的结果表明，逻辑推理和基本心算能力可预测比率处理，而比率处理可预测风险条件下的决策。在第二项研究中，逻辑推理与执行功能共同预测概率处理（数字能力和概率知识），且概率处理可预测风险条件下的决策。这些发现表明，增强个体对比率和概率的理解应会在风险条件下带来更有利的决策。
