Factors that contribute to overcoming decision-making biases in later life pose an important investigational question given the increasing older adult population. Limited empirical evidence exists and the literature remains equivocal of whether increasing age is associated with elevated susceptibility to decision-making biases such as framing effects. Research into the individual differences contributing to decision-making ability may offer better understanding of the influence of age in decision-making ability. Changes in cognition underlying decision-making have been shown with increased age and may contribute to individual variability in decision-making abilities. This study had three aims; (1) to understand the influence of age on susceptibility to decision-making biases as measured by framing effects across a large, continuous age range; (2) to examine influence of cognitive abilities that change with age; and (3) to understand the influence of individual factors such as gender and education on susceptibility to framing effects. 200 individuals (28-79 years of age) were tested on a large battery of cognitive measures in the domains of executive function, memory and complex attention. Findings from this study demonstrated that cognitive abilities such as strategic control and delayed memory better predicted susceptibility to framing biases than age. The current findings demonstrate that age may not be as influential a factor in decision-making as cognitive ability and cognitive reserve. These findings motivate future studies to better characterize cognitive ability to determine decision-making susceptibilities in aging populations.
鉴于老年人口不断增加,有助于克服晚年决策偏差的因素构成了一个重要的研究问题。目前实证证据有限,关于年龄增长是否与决策偏差(如框架效应)易感性增加相关的文献仍存在分歧。对影响决策能力的个体差异进行研究,可能有助于更好地理解年龄对决策能力的影响。研究表明,随着年龄增长,决策背后的认知会发生变化,这可能导致决策能力的个体差异。本研究有三个目标:(1)了解年龄对决策偏差易感性的影响,通过在较大的连续年龄范围内测量框架效应来评估;(2)研究随年龄变化的认知能力的影响;(3)了解性别和教育等个体因素对框架效应易感性的影响。200名年龄在28至79岁之间的个体接受了一系列关于执行功能、记忆和复杂注意力等认知领域的测试。该研究的结果表明,与年龄相比,战略控制和延迟记忆等认知能力能更好地预测框架偏差的易感性。目前的研究结果表明,在决策过程中,年龄可能不如认知能力和认知储备那样具有影响力。这些发现促使未来的研究更好地刻画认知能力,以确定老年人群体的决策易感性。
