The current study aimed to assess: i) whether executive functioning (EF) mediates the association of age with different decision-making (DM) styles in adults, and ii) whether these mediational associations change with age in adulthood. Our sample included 195 adults (110 young adults and 85 middle-aged adults; 95 males) selected from different government, semi-government, and private sector organizations. They were assessed on a self-report measure of General Decision-making Styles and on two EF tests: the Design Fluency Test and the Color-Word Interference Test from the Delis-Kaplan Executive Functions System. Results indicated that EF mediated the association of age with three decision-making styles including dependent, avoidant, and spontaneous DM. However, a conditional indirect effect of EF was significant only for spontaneous DM, indicating stronger indirect effects for middle-aged adults than for young adults. The findings highlight the idea that EF is an important factor in DM, particularly during middle adulthood.

成人的年龄，执行功能和决策风格：适度的调解模型。

当前的研究旨在评估：i）执行功能（EF）是否在成年人中以年龄与不同决策（DM）风格的关系为中介，并且ii）这些中介性关系是否随着成年年龄的变化而变化。我们的样本包括从不同政府，半政府和私营部门组织中选出的195名成年人（110名年轻人和85名中年成年人； 95名男性）。他们是根据一般决策风格的自我报告测度和两个EF测试进行评估的：Design Fluency测试和Delis-Kaplan执行功能系统中的色词干扰测试。结果表明，EF介导了年龄与三种决策方式的关联，包括依赖性，回避性和自发性DM。但是，EF的条件间接作用仅对自发性DM有意义，表明对中年成年人的间接影响要比年轻成年人大。这些发现凸显了EF是DM的重要因素的想法，尤其是在成年中期。
