RESUMO

Research into prospective memory suggests that older adults may face particular difficulties remembering delayed intentions. One way to mitigate these difficulties is by using external reminders but relatively little is known about age-related differences in such cognitive offloading strategies. We examined younger and older adults' (N = 88) performance on a memory task where they chose between remembering delayed intentions with internal memory (earning maximum reward per item) or external reminders (earning a reduced reward). This allowed us to distinguish (a) the absolute number of reminders used versus (b) the proreminder or antireminder bias, compared with each individual's optimal strategy. Older adults used more reminders overall, as might be expected, because they also had poorer memory performance. However, when compared against the optimal strategy weighing the costs versus benefits of reminders, it was only the younger adults who had a proreminder bias. Younger adults overestimated the benefit of reminders, whereas older adults underestimated it. Therefore, even when aging is associated with increased use of external memory aids overall, it can also be associated with reduced preference for external memory support, relative to the objective need for such support. This age-related difference may be driven at least in part by metacognitive processes, suggesting that metacognitive interventions could lead to improved use of cognitive tools.

RESUMO

How do we remember delayed intentions? Three decades of research into prospective memory have provided insight into the cognitive and neural mechanisms involved in this form of memory. However, we depend on more than just our brains to remember intentions. We also use external props and tools such as calendars and diaries, strategically placed objects, and technologies such as smartphone alerts. This is known as 'intention offloading'. Despite the progress in our understanding of brain-based prospective memory, we know much less about the role of intention offloading in individuals' ability to fulfil delayed intentions. Here, we review recent research into intention offloading, with a particular focus on how individuals decide between storing intentions in internal memory versus external reminders. We also review studies investigating how intention offloading changes across the lifespan and how it relates to underlying brain mechanisms. We conclude that intention offloading is highly effective, experimentally tractable, and guided by metacognitive processes. Individuals have systematic biases in their offloading strategies that are stable over time. Evidence also suggests that individual differences and developmental changes in offloading strategies are driven at least in part by metacognitive processes. Therefore, metacognitive interventions could play an important role in promoting individuals' adaptive use of cognitive tools.

RESUMO

Previous research has shown that older adults can have difficulty remembering to fulfill 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 computerized 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 utilize cognitive offloading strategies to compensate for memory decline.

RESUMO

The technological advancement that is rapidly taking place in today's society allows increased opportunity for "cognitive offloading" by storing information in external devices rather than relying on internal memory. This opens the way to fundamental questions regarding the interplay between internal and external memory and the potential benefits and costs of placing information in the external environment. This article reports the results of three pre-registered online experiments investigating the consequences of prior cognitive offloading on A) subsequent unaided ability, and B) strategic decisions whether to engage in future cognitive offloading. We administered a web-based task requiring participants to remember delayed intentions for a brief period and manipulated the possibility of setting reminders to create an external cue. Earlier cognitive offloading had little effect upon individuals' subsequent unaided ability, leading to a small and nonsignificant drop in subsequent performance. However, there was a strong effect on participants' subsequent likelihood of setting reminders. These findings suggest that the short-term impact of cognitive offloading is more likely to be seen on individuals' strategy choices rather than basic memory processes.
