00:24:43.380Well, going off of that, so in the past few years, there's been increasing alarm about screen time, particularly for children.
00:24:53.260Was there any research yet about how screen time affects children's social and intellectual development?
00:25:01.700We don't have all the answers to that question yet.
00:25:04.500And a lot of the research is correlational, so we don't know what comes first.
00:25:10.560But we do know that it's what we call a dose-response effect, meaning the more you drink, the drunker you get.
00:25:18.620The more screen time the kid has, really, the dumber he is in school.
00:25:23.820It's really a very brute, unkind way of saying it.
00:25:27.520And the more behavior problems he or she has, you want to have an impact on your child's social skills and academic achievement, reduce screen time.
00:25:38.820It's absolutely, you know, astounding how, like, essentially how the research is pretty unanimous about the effect of screen time.
00:25:50.220Now, of course, I think there are kids who are immune to this.
00:25:53.520There are kids who will do well in school no matter what.
00:25:56.500These tend to be high-income kids, kids where parents are investing a lot of time and money in their education and their stimulation.
00:26:05.440And I would say for those kids, probably a little bit of screen time or a moderate amount of screen time is probably not going to make a huge difference to them.
00:26:13.660But I would say the middle range of kids and the lower range of kids, either kids who don't get a lot of time, their parents' time,
00:26:23.320either because their parents are working constantly to keep their heads above water financially or because they're single parents
00:26:30.160or because they're newly arrived to the United States or for a whole host of reasons.
00:26:40.960Those kinds of kids are at higher risk of doing more poorly in school because of increased game-playing screen time.
00:26:49.320Because what we know is that, you know, obviously not all time spent on the screen is the same kind of time.
00:26:56.480Some of it could be hugely interesting.
00:26:58.300You could be reading books online or doing all sorts of challenging things.
00:27:04.240But what we do know is that really the path of least resistance is the rule, that if kids are going home and nobody's monitoring it,
00:27:12.240they're watching movies, they're downloading movies and porn if nobody's home to monitor what they're doing.
00:27:19.360And we do know that essentially American kids and British kids are spending more time on the screen on any other activity, including sleeping.
00:27:29.620That's the Pew Internet research that tells us that.
00:27:33.760So for preschool kids, we're talking about four to five hours at least on the screen a day.
00:27:39.860They're sleeping more than that, of course.
00:27:41.960But for school-age kids and teenagers, they're spending more time alone and online than they are doing anything else,
00:27:49.420socializing with their parents, with their friends, or in their beds.
