This fascinating TEDx Rainier talk by paediatrician, researcher and parent Dimitri Christakis is a balanced and well-presented look at media and its effects on early learning. In particular I was surprised by the effects of over-stimulation; prolonged exposure to rapid image change (TV) may precondition the brain to expect high levels of stimulation, leading to inattention in later life.
I am a huge fan of TED and its various conferences and this 15-minute talk has risen to one of my favourites.
