Abstract

The ability to form time-based event expectancies is one of the most important determinants of anticipative behavior. The aim of the present study was to determine whether healthy aging influences the formation of time-based event expectancies. Ten older adults with ages ranging between 60 and 73 years and ten younger adults with ages ranging between 20 and 32 years participated. We employed a binary choice response task mimicking a computer game, in which two target stimuli and two pre-target intervals appeared overall equally often. One of the targets was paired with the short interval and the other target with the long interval in 80% of the trials. Our results showed that younger adults responded more rapidly to frequent interval–target combinations than to infrequent combinations, suggesting that the young participants formed time-based event expectancies. In contrast, the ability to form time-based event expectancies was reduced for older participants. The formation of time-based event expectancies seems to change during healthy aging. We propose that this age-related difference is due to age-related expectation deficits or a reduction of attentional capacities, rather than to deficits in timing abilities.

基于时间的事件预期的年龄相关差异

形成基于时间的事件预期的能力是预期行为最重要的决定因素之一。本研究的目的是确定健康老龄化是否影响基于时间的事件预期的形成。10名年龄在60至73岁之间的老年人和10名年龄在20至32岁之间的年轻人参与了这项研究。我们采用了一个模拟电脑游戏的二元选择反应任务，在这个任务中，两个目标刺激和两个预目标间隔出现的频率大致相同。在80%的试验中，一个目标与短间隔配对，另一个目标与长间隔配对。我们的研究结果表明，年轻的成年人对频繁的间隔目标组合比不频繁的组合反应更快，这表明年轻的参与者形成了基于时间的事件预期。相比之下，年龄较大的参与者形成基于时间的事件预期的能力有所下降。在健康老龄化过程中，基于时间的事件预期的形成似乎发生了变化。我们认为，这种与年龄相关的差异是由于与年龄相关的期望缺陷或注意能力的降低，而不是由于时间能力的缺陷。

期刊介绍： Timing & Time Perception aims to be the forum for all psychophysical, neuroimaging, pharmacological, computational, and theoretical advances on the topic of timing and time perception in humans and other animals. We envision a multidisciplinary approach to the topics covered, including the synergy of: Neuroscience and Philosophy for understanding the concept of time, Cognitive Science and Artificial Intelligence for adapting basic research to artificial agents, Psychiatry, Neurology, Behavioral and Computational Sciences for neuro-rehabilitation and modeling of the disordered brain, to name just a few. Given the ubiquity of interval timing, this journal will host all basic studies, including interdisciplinary and multidisciplinary works on timing and time perception and serve as a forum for discussion and extension of current knowledge on the topic.
