人们对正常的健康老龄化如何影响决策能力知之甚少。在这项研究中，538名参与者（年龄18-80岁）进行了骰子游戏任务（GDT）。子样本还进行了爱荷华州赌博任务以及测量逻辑思维和执行功能的任务。在适度回归分析中，年龄和执行组件之间的显着相互作用表明，具有良好的执行功能的老年参与者在GDT上表现良好，而执行功能降低的老年参与者做出更冒险的选择。同样的模式出现在年龄和逻辑思维的相互作用中。结果表明，年龄和认知功能在预测决策绩效方面是一致的。
Little is known about how normal healthy aging affects decision-making competence. In this study 538 participants (age 18-80 years) performed the Game of Dice Task (GDT). Subsamples also performed the Iowa Gambling Task as well as tasks measuring logical thinking and executive functions. In a moderated regression analysis, the significant interaction between age and executive components indicates that older participants with good executive functioning perform well on the GDT, while older participants with reduced executive functions make more risky choices. The same pattern emerges for the interaction of age and logical thinking. Results demonstrate that age and cognitive functions act in concert in predicting the decision-making performance.
