Also, correlation and causation are being muddled. Autism is triggered by TV? Or a child later diagnosed as autistic watches a lot of TV because they get a lot out of it? So Sigman is maybe suggested rationing or removing the one thing which a particular child finds valuable.
Further, of course, ADHD and similar "disorders" likemild autism spectrum are not at all clearlyscientifically or physiologically defined. Since it isnot clear what they _are_ how can Sigman's research have identified triggers for them?
Maybe the reason some children want to watch so muchis because they are getting a great deal out of it.
He's very worried about people not learning certain skills before three in the "window of the brain's maximum plasticity". But many many very gifted people have hardly spoken at all before the age of 4 (Einstein is the most famous). So much for the blink-and-you-miss-it developmental window.
