Apple research paper hints iPhone habits can predict mental decline with age
Newly-published Apple research argues that seniors not only use iPhone apps differently than their younger counterparts, but that their habits can predict future brain decline.
A paper, "App Usage Predicts Cognitive Ability in Older Adults," was shared during the ongoing ACM CHI Conference on Human Factors in Computing Systems in Glasgow, Scotland. Credited are six researchers -- Mitchell Gordon, Leon Gatys, Carlos Guestrin, Jeffrey Bigham, Andrew Trister, and Kayur Patel -- all of whom work for Apple except for Gordon, who did the research while he was an intern but has since moved on to Stanford University.
In the course of research, Apple collected iPhone data and cognitive test results from 84 otherwise healthy people aged 61 to 76 for three months in 2018. The median age was 66, and 69 percent were women.
"We find that older adults use fewer apps, take longer to complete tasks, and send fewer messages," the researchers say in their abstract. "We use cognitive test results from these same older adults to then show that up to 79% of these differences can be explained by cognitive decline, and that we can predict cognitive test performance from smartphone usage with 83% ROCAUC [receiver operating characteristic area under curve]." Seniors who are "cognitively young" tend to use iPhones like younger people, the paper adds.
The study challenges prior research linking usage differences mostly to culture, values, and lifestyle.
The Apple researchers acknowledge several limitations to their work, among them a relatively small sample size, the absence of a controlled, randomly-assigned experiment, and potential "confounders" like hidden medical and socio-economic conditions. The comparison with younger adults was also based on prior work rather than a newly-recruited batch, and the 84 seniors were given new iPhone 7 units running backups of their existing iPhones, likely resulting in a "breaking-in period" for some.
Ultimately, outside research and meta-analysis will likely be needed to verify Apple's findings.
It's still a rare occurence for Apple researchers to publish papers, mostly a consequence of the company's secrecy. Most of these are about machine learning, though it did collaborate with Stanford Medicine on the Apple Heart Study, which collected data from 419,093 Apple Watch owners.
Apple has shown growing interest in the senior market, for instance adding fall detection to the Apple Watch Series 4. It's reportedly looking to get the Series 3 into the hands of U.S. Medicare users, and iOS has a range of accessibility options.

All that typed, I hope that when I'm his age, I decide I've got better things to do than stare at screens and poke around at gizmo whatsis. I might well "take longer to complete tasks" when I quit partway through whatever I'm doing and mosey or/and saunter around the block.
Maybe they use fewer apps because they don't have ADHD and find a smaller set of practical apps that accomplish everything they need to and they don't always need to jump on the next thing. And maybe they send fewer messages because they put all their thoughts together in a single message instead of sending a text every time some idiot piece of trivia pops into their head and because they don't gossip as much or maybe it's because older people still use email. I bet they'd also find that older people take fewer selfies and don't post every trivial piece of their life on social media, like "I'm at McDonald's and here's a photo of my French fries". And maybe they don't spend as much time on their devices because they have a life outside of those devices and still understand how to interact with real people.
Maybe they do take longer to compete tasks (although I'm 68 and I don't), although I bet a higher percentage of older people know how to type properly.
This sounds like so much b.s. and strikes of ageism. What caused them to study this in the first place? Sounds like they had a theory with a predetermined result and then interpreted their study to get that result.
I think younger people also forget that it's the people who are now "older" who created this industry in the first place. Most of the people who created the microcomputer industry and who developed the web for consumers and businesses are in their 70's now.
It's not a mental deficiency, Apple, it's maturity.
PS: The underlying messages of this "study": 1) If you aren't using our devices, you are crazy. 2) Like, old people are, like, weird.
Cognitive decline and dementia are not limited to the elderly, not anymore.
There is a pretty big uptick in cognitive decline in younger age groups and no common denominator at this time.
I have met more elderly people who have their stuff together in life, so they don’t require multiple apps and to be on their devices all of the time like younger people do.
Btw, fall detection on the watch should be on by default no matter what age you are.
I work with seniors routinely, and I would say that this study is flawed -- but not in the way most commenters above me would. A major factor that has likely not been incorporated into the study is that these older folks didn't grow up with any of this as "normal", and IME it is their quest for new learning (i.e., how enthusiastic they are about learning new things or finding ways to accommodate their other abilities) that marks whether they will be "cognitively young" or not.
The other week I taught a fellow who had really been struggling with his iPhone how to dictate his reminders, notes, appointments, email, and issue some commands by voice -- like "open ebay.com" -- and after some practice to remember the key words needed and how to "compose your thought" before you speak, this one "trick" has increased his use of the iPhone tenfold. His big issue was that he really couldn't deal with the tiny keyboard on iPhones, and wasn't good at remembering the little differences between apps and how they worked.
I'm delighted to hear that Apple is focusing more on seniors -- the basic services have been there for a long time, but the recent enhancements in health and what they used to call "universal access" will really make a difference if they leverage these abilities in some senior-targeted ads (that appear mostly where young people wouldn't see them -- don't want to look "uncool" ya know!).
I too would like to see more apps that are considerate of the needs of seniors and people with physical and cognitive limitations. To some degree, I think that highly engaging apps that challenge memory and recollection are helpful for seniors, but from personal experience I know that no app on the planet can reverse or help compensate for the permanent negative effects associated with dementia and Alzheimer’s disease. But these concerns are at the extremity and there are many compensation actions that could be incorporated into apps to make them more attractive and useful for seniors.
To put a positive spin on this, if you’re an app developer looking to tap into an underserved market, consider taking an empathetic approach to solving some of the basic needs of seniors that can be delivered on mobile platforms. This may provide a path to a very lucrative payback as the senior population continues to expand.
Again, bad study, bad conclusion.
