As the world we live in continues to become more technologically advanced, questions of electronic media use will continue to be raised by concerned parents. To begin, there is some evidence that screen use for babies might be harmful, so the first thing to consider is the age appropriateness of screen time. A study completed in 2007 found that the more television children watched before age three, the more difficulty those children had regulating their attention spans at age seven. The moderating factor found in 2007 was the whether the program was educational or entertainment based. Educational program was found to have less of a harmful impact, possibly because of the care taken to ensure the programs created for this age range are mindful of things like over-stimulation and age-appropriate learning. Another negative finding of the 2007 study was that children between the ages of two and 24 months who were allowed more screen time often experienced language delays. The suggestion for this age group would be that screen time should be moderated, and options should be limited to educational programming whenever possible.
In children who are 12-30 months, screen time can actually provide some benefits. Children in this age range can learn from videos, and will imitate the actions seen on screen. Again, the caution would be the type of programs watched, as children in this age group have a difficult time separating imagination from reality. By preschool age, the benefits children can see from educational TV include school readiness, language development and beginning math skills including counting and simple addition. This learning is even greater when children are given the opportunity to talk about the programming they have watched with parents, who can easily engage in child-led conversation following their allotted screen time.
