Study links TV watching to autism
Ongoing research at Cornell University has revealed a possible link between autism and children under the age of three who watch television. The study found that when cable became more prominent in households in the '80s, autism rates also increased. The study has not found anything specific in television viewing that may trigger autism in young children, only that there is a strong correlation between the two. Some have pointed out it may not be television, but indoor air pollution that may be the root of the problem.
While experts study this and try to come to a consensus, I think laypersons should see this as a reminder that too much television exposure at a young age is not a good thing. As Slate's Gregg Easterbrook points out in his article, humans evolved responding to three-dimensional stimuli, and repeated exposure to two-dimensional images, whether it turns out to be directly linked to autism or not, is still not a good thing in the early stages of development.
