An Apple research paper called “App Usage Predicts Cognitive Ability in Older Adults” says that iPhone usage can help predict cognitive decline in older adults [PDF].
To characterize smartphone usage among older adults, we collected iPhone usage data from 84 healthy older adults over three months. We find that older adults use fewer apps, take longer to complete tasks, and send fewer messages. 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. While older adults differ from younger adults in app usage behavior, the “cognitively young” older adults use smartphones much like their younger counterparts. Our study suggests that to better support all older adults, researchers and developers should consider the full spectrum of cognitive function.
Last night I came across a website called Appademic, which shares academic shortcuts that can help students and researchers. One example is a shortcut that gives you better BibTeX citation keys for Pandoc.
This is the long awaited iOS Shortcut for Zotero to extract Better BibTeX citation keys for Pandoc. I know a fair few people have been waiting on this, apologies it has taken so long to post. If you need more detail, read on, otherwise the shortcut can be downloaded below.
Recently I wrote a PSA on Wi-Fi and cancer, and a lot of people disagree with me by sending me links to studies and other news that also disagree. That’s fine, but at the same time a lot more effort goes into scientific research than cherry picking Google results. I don’t claim to know better than these studies, but a scientific study needs to be taken into context of the field as a whole. John Oliver had a good segment on studies and how they can be misunderstood. Compound Interest has a rough guide to spotting bad science and red flags to watch out for. I’ve made use of this guide for some time, and I think it’s helpful.
This graphic looks at the different factors that can contribute towards ‘bad’ science – it was inspired by the research I carried out for the recent aluminium chlorohydrate graphic, where many articles linked the compound to causing breast cancer, referencing scientific research which drew questionable conclusions from their results.
Apple is donating a thousand Apple Watches to a binge eating study. The University of North Carolina’s medical school will start this study.
Apple brand recognition is at the top in the technology industry among millennials, beating Microsoft, Intel, IBM, HP, and Dell.
In a new research paper published by Vanderbilt University’s Professor Douglas Schmidt, it found that Android phones suck up your data.
We don’t know if the users whose data was collected were asked for permission.
A paper from the National Bureau of Economic Research suggests that owning an iPhone is a sign of wealth. The iPhone study was done by economists Marianne Bertrand and Emir Kamenica.
Apple is changing course and letting its engineers publish their research into artificial intelligence. John Martellaro and Bryan Chaffin join Jeff Gamet to share their thoughts on why Apple would do that, plus they respond to a listener comment questioning why Jeff is critical of HomeKit.
