“It is unclear whether the technology staves off mental decline, or whether people with better cognitive skills simply use them more.”
It’s very early stages of the research then. In my experience elderly people use smartphones very differently to kids. Also, their personal development has past the formative stages so I imagine the devices cause less disruption.
There’s no doubt that they ruin the brains and lives of our kids though, as the research video posted on Lemmy.world recently makes clear.
Edit: Here it is. Brain scans show that screen addiction is the same as drug addiction as far as development of brain pathway changes and brain chemistry are concerned. Only difference is we haven’t had addicts this young and at this scale before. Memory, empathy, cognition and impulsivity are all impacted. https://www.youtube.com/watch?v=1ViT6LyLm6E
