Reminders Reduce Age-Related Memory Decline in Older Adults
October 24, 2024
Summary: A new study shows that using reminders can counteract age-related declines in memory, especially for tasks that require prospective memory, such as taking medication. Researchers found that reminders help both younger and older adults improve memory performance under high cognitive load.
This breakthrough suggests that digital tools, like smartphone apps, can significantly aid older adults in maintaining independence and managing daily tasks. The study highlights the potential of reminders in mitigating memory challenges associated with aging.
Key Facts:
- Reminders eliminate age-related memory declines in high-load conditions.
- Prospective memory, crucial for daily tasks, benefits significantly from reminders.
- Tools like smartphone apps can help older adults manage memory challenges.

A new study from UT Arlington reveals that setting reminders can eliminate some age-related declines in memory.
The findings offer a significant breakthrough in addressing the cognitive challenges faced by older adults, particularly in the context of prospective memory, which is the ability to remember to perform an intended action at the right moment, like taking medication or attending appointments.
“Prospective memory is essential for daily living and maintaining independence, especially as people age,” said Hunter Ball, associate professor of psychology at UTA and lead author of the study.
“Failing to remember these forward-looking tasks can lead to serious consequences, and previous research has shown that prospective memory tends to decline with age.”
Conducted with psychologists at UTA and Arizona State University, the study involved two experiments that tested prospective memory performance in younger and older adults under varying conditions with or without the aid of reminders.
Participants were asked to remember specific tasks while completing ongoing activities, and their performance was measured in both high-load (more items to remember) and low-load conditions (fewer items to remember).
In the first experiment, participants were given specific tasks to remember, such as responding to certain words, and some were provided with reminders displayed on-screen.
The results showed no significant age-related decline in prospective memory without reminders under low load, but under high load, both younger and older adults benefitted equally from using reminders. This suggests that reminders can help reduce cognitive strain by making memory retrieval less reliant on internal memory processes.
The second experiment introduced more complex, nonspecific tasks that required participants to recognize categories, such as animals or fruits, rather than specific words.
Older adults experienced more difficulties in remembering these nonspecific tasks under high memory load without reminders, but these age-related performance gaps were eliminated entirely when reminders were available.
This finding was critical as it highlighted the potential for reminders to counteract the deficits associated with more cognitively demanding tasks that typically strain older adults’ memories.
Ball and his colleagues suggest that the effectiveness of reminders for older adults stems from their increased tendency to check reminders more frequently when faced with high cognitive demands. This compensatory behavior likely helps older adults manage tasks that would otherwise be too taxing on their internal memory resources.

The authors highlight that digital tools like smartphone apps, personal assistants like Amazon Alexa, or even simple reminder notes can serve as valuable aids for older adults in managing their daily tasks effectively and maintaining their independence.
“This new study demonstrates that cognitive offloading, specifically using reminders like cell phone calendars, can effectively mitigate these declines,” said Ball.
“While our study was conducted in a controlled setting, these findings can easily be applied in real-world environments as a way to provide easy and effective way to alleviate the burden of prospective memory challenges in older adults.”

Abstract
Reminders eliminate age-related declines in prospective memory
Prospective memory (PM)—the process of establishing intentions for future action and remembering to fulfill these intentions at the appropriate time—is necessary for many instrumental activities of daily living and for maintaining functional independence with increased age.
Offloading PM demands onto the environment, such as setting a reminder alarm to take medication, offers an easy and effective way to mitigate age-related PM declines. However, a lack of basic knowledge about the cognitive and metacognitive processes that drive offloading decisions presents barriers to successful implementation.
With nonspecific intentions that require top-down attention for retrieval (Experiment 2), older adults had worse PM under high load without reminders. Critically, this age difference was eliminated with the use of reminders, likely due to increased reminder checking for older adults under high load.
These findings suggest that offloading can circumvent cognitive capacity limitations and minimize computational effort to improve intention fulfillment in older adults. The theoretical and applied ramifications of these findings are discussed.
