It obviously wouldn’t be ethical to test for the effects of a whole childhood spent in front of screens on children. A few years ago, researchers came up with perhaps the next best thing. Affixing colorful lights and speakers broadcasting Cartoon Network sounds to mouse cages, they subjected young mice to six hours of “television” for 42 days straight.
Seattle Children’s Research Institute director and pediatrician Dimitri Christakis presented the spooky results at a TEDx Talk in Washington: In an observation box, the control mice traveled along the perimeter—your standard, cautious, don’t-get-caught-in-the-open mouse behavior, while the media-binge rodents scurried all around and every which way. They’d turned into hyperactive risk-takers.
