Oh, and only these two social media sites? Or we're only going to headline echo that it is TikTok? Why does this smell like out of control propaganda?
Write this headline about Mastodon and no one would read it.
I haven’t read the study, but I’ve read the comments so far. I wonder if this mechanism is the same mechanism that impacts, say, swipe-focused dating websites, as well? And Twitter feeds with super-short messages. A lot of the most viral modern tech has been bite-sized content feeds of various types.
dlPFC deactivation is observed in a lot of immersive tasks. There are a lot of tasks that do this. Playing video games, as one example https://link.springer.com/chapter/10.1007/4-431-26797-2_11 Interpreting fMRI results like this article does is almost always wrong. Different activities produce different patterns of brain activity. You could put someone in an fMRI machine, have them do virtually any activity, and the…
And that's leaving aside the question of what it would affect. Elasticity/learning? Would it result in forgetting, or losing skill? Apart from the problem that I (and others with me) have with the "area X does Y" school of neuro-cognition, measuring changes in activity does not measure changes in connections, synapses, or tissue. It is possible that inhibiting certain brain areas for a longer period will change e.g.…

Earlier quoted context omitted.
Now that is what I call a series ahead of its time! Also saw it as it came out, had totally forgotten about that word.
I was young, and it was like a fever dream. I couldn't believe that was on TV. It was pretty darn subversive.
We’re living down to it.

This could equally be reported as tiktok puts the mind at ease.
Or tiktok reduces brain activity related to anxiety.
"Related to" is a term that seems to be capable of supporting an unlimited load.
While this podcast episode is not about this particular research, it could have been.

It used to be that reading books made you an intellectual. In the age of TikTok and shorts being able to watch a movie for 2 hours makes you an intellectual.
The brain is incredibly energy hungry so it evolved to detect situations that don’t require full attention and activates the Default Mode Network. This happens when you’re zoning out to pretty much anything, and indicates that you’re essentially in “low power mode”. My question here is whether the framing of the content in question “shutting off brain regions” is an honest one compared to what I said above. fMRI is a…
This "low power mode" is a myth, the brain pulls a pretty constant amount of power (about 20% of metabolic energy), and most power isn't consumed by the action potential/neurons firing, but rather in keeping the neuron ready to fire. And the regions involved in the default mode network are actually some of the metabolically most active regions in the brain, involved in memory consolidation, future simulation, theory…

It’s task-specific.

I’d posit that we just puritanically glorify anything perceived as difficult, regardless of the correlation with “intellect.” I’m fine not having the same attention span as people who had to less stuff to do hundreds of years ago.
