Delay discounting (or temporal discounting) refers to the decrease of the subjective value of a reward as the time interval for receiving that reward increases. A recent meta-analysis showed that delay discounting appears to be similar across the lifespan as younger, middle-aged, and older adults prefer sooner rewards, despite smaller, over later rewards, even if larger. However further investigation is needed to understand the potential role of individual factors in delay discounting across the lifespan. The present study aimed to contribute to this debate, by investigating the influence of sociodemographic, neurocognitive, and psychological variables on delay discounting. For this purpose, 88 participants (30 younger, 30 middle-aged, and 28 older adults) aged between 19 and 73 years old completed the Monetary Choice Questionnaire (MCQ), a comprehensive battery of neurocognitive tests, and self-report measures of psychopathology. Results revealed no group differences in the rate of discounting. A well-established effect of the amount of the delayed reward was replicated, showing that medium rewards were less discounted than smaller rewards, and larger rewards had lower discounting rates than smaller and medium rewards-the magnitude effect. Regarding the influence of neurocognitive and psychological factors on delay discounting, better working memory, as assessed by the Corsi block-tapping task, significantly predicted larger magnitude effects. The findings of the current work are consistent with the results of previous studies, suggesting that temporal discounting is a stable function across the adult life span.

衰老中的延迟折扣：认知和心理变量的影响。

延迟折扣（或时间折扣）是指奖励的主观价值随着接收奖励的时间间隔的增加而降低。最近的一项荟萃​​分析表明，延迟折扣似乎在整个生命周期中相似，因为年轻、中年和老年人更喜欢较早的奖励，尽管较小，而不是较晚的奖励，即使更大。然而，需要进一步调查以了解个体因素在整个生命周期中延迟折扣中的潜在作用。本研究旨在通过调查社会人口、神经认知和心理变量对延迟折扣的影响，为这场辩论做出贡献。为此，年龄在 19 至 73 岁之间的 88 名参与者（30 名年轻人、30 名中年人和 28 名老年人）完成了货币选择问卷 (MCQ)，一套全面的神经认知测试和精神病理学的自我报告测量。结果显示贴现率没有组间差异。延迟奖励金额的既定效果被复制，表明中等奖励的折扣低于较小奖励，较大奖励的折扣率低于中小奖励 - 幅度效应。关于神经认知和心理因素对延迟折扣的影响，更好的工作记忆，正如 Corsi 块敲击任务所评估的那样，显着预测了更大的幅度效应。当前工作的结果与之前的研究结果一致，表明时间贴现在整个成人生命周期中是一个稳定的函数。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。
