Is short-form video affecting your kid's focus?


Hi Reader,

47 seconds. That’s about how long we stay on one screen before switching to something else, according to UC Irvine researcher Gloria Mark. When she started measuring in 2004, it was two and a half minutes.

Now think about what our kids practice every time they open TikTok, Reels, or YouTube Shorts. Swipe. Something new. Swipe. Something new. Every few seconds, the brain gets a fresh hit of something new, and it never has to stay with anything slow or boring.

That practice seems to show up in the research. A 2025 meta-analysis of 71 studies and nearly 100,000 people found that heavier short-form video use was linked to weaker attention and weaker inhibitory control, which is the ability to pause before acting on an impulse. Those two had the strongest associations in the whole analysis.

One important caveat: this research is correlational. We can’t say short form videos cause attention problems. It’s just as likely that kids who already struggle to focus are drawn to fast, frictionless content. For kids with ADHD, that’s the heart of the issue. The kids whose attention systems are already working hardest are the ones most pulled toward the feed, and the feed trains the opposite of what school, reading, and conversation ask of them.

So what do we do? We don’t panic, and we don’t ban everything. We protect some slow time:

  • Turn off autoplay wherever you can. Friction is your friend.
  • Choose content with a beginning, middle, and end. A full episode or a movie they picked on purpose asks more of their attention than a feed that picks for them.
  • Let boredom happen. Boredom is the space where sustained attention gets built.

This is exactly the kind of practical, judgment-free approach I cover in my session, “Wired Differently: Using Tech Intentionally With Your Child,” at the ADHD & Executive Function Summit. It’s a free online event. By signing up, you get access to interviews of 30+ experts to watch on your own time. The summit runs from October 5-11, but spots are limited, so sign up now.

Hi Reader, The other day, I heard a parent describe their child like this: “The phone is basically an extension of her body. She doesn’t go anywhere without it.” She’s 12 and got a phone for her birthday. Her parents asked her to be mature and responsible with it, but things slowly got out of hand. She used to love going on bike rides with her neighborhood friends. Now, she spends all of her after-school hours lying on her bed scrolling. They shared that the phone had become “her entire...

Hi Reader, I don't know about you, but October has been a doozy in my house. We battled head lice (so gross). I got COVID for the first time ever (turns out I’m not one of those super humans who never gets symptoms like I thought I was). And work has been busy, to say the least. And then, of course, my younger daughter started having intense nightmares. All it took was one conversation in the car about the Wicked Witch from The Wizard of Oz. Here’s the thing: she never saw the movie. There...

Hi Reader, A few weeks ago, we were on a road trip with our daughters. As we were driving, my 6-year-old asked from the back seat: “How many days would it take to walk from here to New York?” It’s the kind of question you hope your kid will ask. My husband asked AI right away. Within seconds it gave a clear, accurate answer: about four months, including rest days. And I immediately wished we’d handled it differently. No shade on my husband. Most of us would have done the same thing. Asking AI...
