Time-of-day affects prospective memory differently in younger and older adults

Rothen, Nicolas; Meier, Beat (27 March 2017). Time-of-day affects prospective memory differently in younger and older adults (Unpublished). In: 59th Conference of Experimental Psychologists - Tagung experimentell arbeitender Psychologen (TeaP). Dresden, Germany. 26.03.-29.03.2017.

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.
