I know it is recommended that kids not watch TV till they are at least two years old, and even then that TV viewing be pretty minimal.
However, I wonder what are the actual detriments to kids older than two? I know too much TV impedes children's time to engage in other important activities, but What are the scientifically backed detriments? There are actually a number of questions that inspire this question:
Is looking at a computer monitor the same as viewing the TV?
What about Participating in games on the computer or on a gaming system?
How about watching an older sibling participate in these activities (supposing the content being viewed is age appropriate. . .
Does the detriment still apply when they are teens? Adulthood?
I don't expect answers to specifically address all of my example questions, I'm just trying to make the line of thinking clear here - I'm not asking about content and anecdotal reasoning, but real, scientifically backed evidence about what the harm really is for toddlers, school-aged kids and on up the ages and is really "screen time" in general that should be of concern or only TV?
Please realize there is a question that addresses concerns that apply to infants Is TV Harmful to My Infant's Development and one that addresses eyesight concerns of toddlers that watch and sit too close where I feel these questions are already answered sufficiently. I understand and see that there are concerns regarding social interaction and language development that do specifically apply to the youngest of us. I'm wondering about other types of impacts and impacts for the older age groups.
