older adults’ – Two smartphone-based studies suggest older adults may recall autobiographical experiences with surprising richness outside the laboratory—challenging decades of lab findings that link reduced detail to cognitive decline.
In lab interviews, older adults often struggle to come up with the granular details of past experiences. That pattern has helped shape a widely used story about aging: as years add up, memory fades, and recollections become thinner.
But two new studies push back—using smartphone methods that capture how people talk about their lives when they’re not sitting under a researcher’s gaze. The results don’t deny that aging affects memory. They argue that the way memories are measured may be steering the outcome.
Matthew Grilli, a psychologist at the University of Arizona in Tucson, points to decades of lab-based work on autobiographical memories. In those studies, experimenters typically interview participants about past events. The lab results have shown older adults can recall fewer details than younger adults. and the effect has appeared more pronounced in people with dementia. That evidence helped many researchers treat the shift as a sign of cognitive decline.
Grilli and colleagues wanted to test whether that picture holds up in everyday life.
In a study accepted for publication in the Journal of Experimental Psychology: General. the researchers recruited 24 young adults between the ages of 18 and 28 and 50 older adults between the ages of 61 and 81. The participants downloaded a smartphone app that randomly recorded 30-seconds of audio five times per hour for 14 hours a day. After 10 continuous days of recording. the researchers sifted through the sound files for moments when people shared autobiographical memories. then analyzed the content of those recollections. The participants also came into the lab for more traditional, in-person interview-based assessments.
The comparison was striking. In everyday conversations, older adults showed no significant difference in their ability to recount details compared with their younger counterparts. Grilli said the findings suggest 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.”.
A second study supported the same general direction, using a different smartphone approach. Published in January in PNAS, it assessed autobiographical memory recall in more than 1,900 adults between 18 and 89 years of age. Instead of recording audio during conversations, the technique pinged participants throughout the day to ask about their thoughts. In that study, older adults reported their past thoughts with more specificity and vividness than their younger counterparts.
The researchers still don’t know why the gap between lab and daily life appears in older adults.
Jessica Andrews-Hanna, a cognitive neuroscientist at the University of Arizona and a coauthor of both studies, offered two possible explanations. One is that the laboratory context may be less familiar to older participants than to younger ones. who are often students on the campus where this type of work is carried out. Another is that experimenters are often young adults themselves. which could make older participants feel they need to provide more background context before describing what they remember.
There’s also uncertainty about accuracy.
Andrews-Hanna said it’s still unclear whether participants’ memories were accurate. Yet she added that the lived way people experience and share memories in everyday life may be a more sensitive marker of disease-related cognitive decline than accuracy alone.
Outside scientists urged caution even as they acknowledged the central point: the standard lab frame may be too narrow.
Daniel Schacter. a psychologist at Harvard University who was not involved in the work. said the field needs more studies on aging that go outside the laboratory and look at memory and related function in a more naturalistic context. He also noted that factors such as a person’s narrative style can help explain differences in autobiographical recall reported in the lab.
Brian Levine. a scientist at the Baycrest Academy for Research and Education in Toronto who was also not involved. emphasized that aging does indeed affect memory. Difficulty remembering the details of past episodes is one of the most common complaints of aging. But Levine argued that the way older adults use their memories may differ from how younger adults do. “When we bring them into the lab and test them on things that are not optimized to their needs. then they’re going to look more impaired than they really are. ” he said.
The question now isn’t whether memory changes with age. It’s whether the methods used to study those changes are capturing the full story—or accidentally cutting out the very conditions where older adults’ recollections show their real depth.

So you’re saying my grandma’s memories aren’t getting worse, they’re just being measured wrong?
This is kinda confusing. Like, if lab people can’t remember details, doesn’t that mean they do have cognitive decline? Or are they just bad at interviews? Seems like either way it’s not great.
Wait I saw this on TikTok too and I think they said older folks remember more because the phone app listens at random times?? But what if they’re just talking anyway and it gets recorded, like not really “recalling” anything. Either way I’m skeptical but also… I don’t know.
Lab studies are always off, right? Like they sit you in a room and ask you to remember stuff, of course it’s gonna be worse. But I don’t get how a phone recording 30 seconds five times an hour proves memory is “rich.” Dementia is real, so this feels like they’re minimizing it. Also 14 hours a day recording sounds terrifying honestly.
