MRIs show screen time linked to lower brain development in preschoolers

Screen time use by infants, toddlers and preschoolers has exploded over the last decade, concerning experts about the impact of television, tablets and smartphones on these critical years of rapid brain development.

Now a new study scanned the brains of children 3 to 5 years old and found those who used screens more than the recommended one hour a day without parental involvement had lower levels of development in the brain’s white matter — an area key to the development of language, literacy and cognitive skills.

"This is the first study to document associations between higher screen use and lower measures of brain structure and skills in preschool-aged kids,” said lead author Dr. John Hutton, a pediatrician and clinical researcher at Cincinnati Children’s Hospital. The study waspublished Monday in the journal JAMA Pediatrics.

And they used to say too much television would rot your brain...

1 This is one instance where the nebulous "they" hit the nail on the head.

I am mournful when I see little kids playing with expensive cell phones, watching videos of whatever, instead of being obliged to interact with the world around them. I almost made that point to a mother in church the other day about her three-year-old; I've been discussing other things with her (biblical dates, in fact), and she's certainly smart enough (PhD in languages ought to tell you something). I just don't feel comfortable about getting in peoples' faces about parenting issues.

2 Yes, Dana; it IS sad to see kids being absorbed by these gadgets. And I do mean absorbed.

Not that it's just kids; I was at a microbrewery with my buddy Dave and we were amazed at all the people sitting in the bar thumbing their gadgets. Why go out at all? You could just buy a growler - or a good old six pack - and drink it at home. You can use a computer with a bigger screen that way.

3 Cathy and I once went to a restaurant and a couple was clearly on an early date, but they both sat there playing on their gadgets. What kind of world are we creating?

4 Well, at the brewery, I can imagine folks taking photos of the brews they really liked, for future reference. Been known to do that myself.

When these phones with cameras first came out I couldn't for the life of me understand what good a camera would be on a phone. Man, did I learn! We use our phones to deposit checks into our bank account (in fact it's the only way), for example.

I'll be doing the grocery shopping, Martha needs a... women's product, they've changed the packaging (they do it every six weeks or so, it seems), and I take pictures, text 'em to her and say "Which do you want?"

I even texted with Martha once when I was sitting right next to her, but there were "extenuating circumstances." I was being fitted for a new hearing aid and my ear was full of putty, for an impression for the new earpiece. Bearing in mind that I have only one ear that works, it meant I was stone deaf.
