Abstract

Objective: Delay discounting refers to the devaluation of future rewards as a function of time. Previous studies proposed the relationship between time perception and delay discounting in ageing, while there is a lack of evidence about the effect of different dimensions of time.

Method: This study explored the effect of delay length (1-day, 1-month, 6-month, 1-year, 5-year), time framing (delay, date) and time estimation (internal clock) on delay discounting in younger and older adults. Seventy younger adults and 57 older adults completed the delay discounting task and time estimation task.

Results: Results suggested the effect of age, but there were no effects of delay lengths and time framing on age differences in delay discounting. Meanwhile, internal clock predicted delay discounting in older adults, with higher discounting correlating with more internal clock variability.

Conclusion: Age differences in delay discounting may not be due to the effects of delay lengths and time framing, but rather to variations in the internal clock among older adults.

时间对年轻人和老年人延迟折扣的影响。

目的：延迟贴现指的是未来奖励作为时间函数的贬值。以往的研究提出了时间感知与延迟贴现之间的关系，但缺乏关于不同时间维度影响的证据。方法：本研究探讨延迟长度（1天、1个月、6个月、1年、5年）、时间框架（延迟、日期）和时间估计（内部时钟）对年轻人和老年人延迟折扣的影响。70名年轻人和57名老年人完成了延迟贴现任务和时间估计任务。结果：年龄对延迟折扣有影响，但延迟长度和时间框架对延迟折扣的年龄差异没有影响。同时，内部时钟预测了老年人的延迟折扣，更高的折扣与更多的内部时钟可变性相关。结论：延迟折扣的年龄差异可能不是由于延迟长度和时间框架的影响，而是由于老年人内部时钟的变化。

The journal publishes high quality peer-reviewed articles with reviewers and associate editors providing detailed assistance to authors to reach publication. The journal publishes reports of experimental and survey studies, including reports of qualitative investigations, on pure and applied topics in the field of psychology. Articles on clinical psychology or on the professional concerns of applied psychology should be submitted to our sister journals, Australian Psychologist or Clinical Psychologist. The journal publishes occasional reviews of specific topics, theoretical pieces and commentaries on methodological issues. There are also solicited book reviews and comments Annual special issues devoted to a single topic, and guest edited by a specialist editor, are published. The journal regards itself as international in vision and will accept submissions from psychologists in all countries.
