The first study (1) covered more than 11,000 young Americans. The authors begin with an observation: between 3 and 5 years, children watch TV more than two hours per day. And 59% of children under two years already watch an hour and a half on average, despite the fact that there is no educational value to programs for toddlers.
At the age of 6-7 years, these same children have spent cognitive tests, including a math test. Performance was lower among children who have watched televisionbefore the age of 3 years. However, the hours spent in front of the screen between 3 and 5 years appeared to promotecognitive, Particularly with regard to reading and short-term memory. But any benefit in mathematics or reading comprehension was observed.

The second study (2) dealt with 1000 New Zealand children followed since the age of 5 years. After noting every two years the amount of television watched, the authors find that more time spent watching TV is between 13 and 15 years, more children were likely to leave school without qualifications. However, the fact of just watching TV between 5 and 11 years, is a preacher of goodlevel studyto 25 years. Overall, time spent in front of the screen is inversely proportional to the chances of going to university. And that time spent watching TV during theEarly Childhoodwhich has the most influence, compared to that spent during adolescence.

And finally, the third study (3) analyzed the performance of 350 school children in California aged 8-9 years, depending on the family media equipment. Those who hadTV in their bedroomgot a score to a mathematical test of eight points lower than the others. These children also had poorer performance on tests of reading and language. In contrast, children who had home access to a computer (30% of children studied) obtain test scores by 8 percentage points higher than the others.

In conclusion, it would be best to avoid TV before age 2 years or 3 years, not to put TV in the bedrooms of children, limit the time to one or two hours per day control programs. Remember that time spent watching TV is also proportional to the risk of obesity!
