New research suggests that older adults' memory of past events may be much better than traditional lab tests indicate. Using smartphone recordings, scientists discovered that when older people describe memories in their everyday lives, they recall details just as well as younger people do.
The Research
In a study accepted for publication in the Journal of Experimental Psychology: General, psychologist Matthew Grilli from the University of Arizona and colleagues tracked the natural conversations of 24 younger adults (ages 18–28) and 50 older adults (ages 61–81). Participants used a smartphone app that randomly recorded 30‐second audio clips about five times per hour for 14 hours a day, over 10 consecutive days. The researchers analyzed these clips for moments when people shared autobiographical memories and compared them to traditional in‐person interviews.
They found that in everyday conversations, older adults showed no significant difference in the detail of their recollections compared to younger adults. The earlier lab‐based studies had shown older adults recalling fewer details, but that pattern seems to disappear outside the lab.
Another study, published in PNAS in January 2026, supported these findings. Grilli and his colleagues used a different smartphone method—sending prompts throughout the day—with more than 3,800 adults aged 18–89. They discovered that older adults reported their past thoughts with more specificity and vividness than younger adults.
This suggests that the settings where we test memory matter. Lead author Grilli says researchers “may need to take a step back from the assumptions that we make about how autobiographical memories may or may not change in older age based on laboratory research, which might not be capturing the whole picture.”
Jessica Andrews-Hanna, a cognitive neuroscientist and coauthor of both studies, thinks older participants may be less comfortable in unfamiliar lab settings. They might also feel the need to provide more background because the experimenters are often young adults.
Why It Matters
These findings challenge the idea that memory decline is an inevitable part of aging. If older adults can recall past events vividly in real life, then standard lab tests may underestimate their true cognitive abilities. This could change how we evaluate memory problems and what we consider “normal” aging.
The way people share memories in everyday life might even be a better gauge of dementia‐related decline than lab accuracy, says Andrews-Hanna. So it’s crucial to develop naturalistic methods to study cognition.
What You Can Do
Even if you notice occasional memory lapses, remember that context matters. Try associating new information with personal experiences and practice recalling stories from your day in detail—this can help maintain memory skills. If you’re concerned about memory loss, consult a healthcare professional for a comprehensive evaluation that includes real-world activities.
