Second, too much TV—especially programming of low educational value—can reduce people’s ability to concentrate or reason. In fact, studies show that after only a minute or two of visual media, a person’s mind “relaxes” as it does during light sleep. Another possible effect of television and videotapes on the human brain is poor communication. Children who watch a lot of TV may lose their ability to focus on a subject or an educational activity for more than 10 to 15 minutes. Maybe it is because of the visual media that some kids—and adults too—develop attention deficit disorder (ADD), a modern condition in which people are unable to pay attention, listen well, follow instructions, or remember everyday things.
