Age differences in strategic reminder setting and the compensatory role of metacognition

Previous research has shown that older adults can have difficulty remembering to fulfil delayed intentions. In the present study, we explored whether age differences in prospective memory are affected when participants are permitted to set reminders to help them remember. Furthermore, we examined whether metacognition can influence the use of such strategies and help older adults compensate for age-related memory decline. In this pre- registered study (N = 88) we administered a computerised task requiring a sample of older (aged 65-84) and younger (aged 18-30) participants to remember delayed intentions for a brief period, manipulating the possibility of setting reminders to create an external cue. Performance of the older group was significantly poorer than the younger group. Moreover, older adults were overconfident in their memory abilities and did not fully compensate for impaired performance, even when strategic reminder-setting was permitted. These findings suggest that older adults possess limited metacognitive knowledge about their prospective memory limits and may not fully utilise cognitive offloading strategies to compensate for memory decline.
