The goal of this study was to investigate the impact of circadian arousal on prospective memory performance as a function of age. We tested a younger (18-34 years) and an older group (56-95 years) of participants on- and off-peak with regard to their circadian arousal patterns in a computer-based laboratory experiment. For the prospective memory task, participants had to press a particular key whenever specific target words appeared in an ongoing concreteness-judgment task. The results showed that prospective memory performance was better on- than off-peak in younger but not older participants. Younger participants consistently outperformed older participants in all conditions. We conclude that prospective remembering underlies time-of-day effects which most likely reflect controlled processes.
本研究的目的是调查昼夜唤醒对前瞻性记忆表现的影响，并将其作为年龄的函数进行研究。在一项基于计算机的实验室实验中，我们针对昼夜唤醒模式的高峰和低谷时段，对一组较年轻（18 - 34岁）和一组较年长（56 - 95岁）的参与者进行了测试。在前瞻性记忆任务中，每当特定目标词出现在正在进行的具体性判断任务中时，参与者必须按下一个特定的按键。结果显示，较年轻参与者的前瞻性记忆表现在高峰时段优于低谷时段，而较年长参与者则不然。在所有条件下，较年轻参与者的表现始终优于较年长参与者。我们得出结论，前瞻性记忆是昼夜效应的基础，而昼夜效应很可能反映了受控过程。
