G) Hancox's team found that watching TV at an early age had the most effect on graduating from college. "An interesting finding was that although teenage viewing was strongly linked to leaving school without any qualifications, it was earlier childhood viewing that had the greatest impact on getting a degree," he said. "This suggests that excessive television in younger children has a long-lasting adverse effect on educational performance."
H) In the third paper, Frederick J. Zimmerman and Dr. Dimitri A. Christakis from the University of Washington report that, for very young children, watching TV can result in lower test scores in mathematics, reading recognition and reading comprehension. "We looked at how much television children watched before age 3 and then at ages 3 to 5," Zimmerman said. "We found that for children who watched a small amount of TV in the earlier years, there was co nsider able beneficial effect compared to children who watched a lot of TV."
I) For children aged 3 to 5, the effect was not as clear, Zimmerman said. "There were some beneficial effects of watching TV on reading, but no beneficial effects for math or vocabulary," he noted. "The worst pattern was to watch more than three hours of TV before age 3. Those kids had a significant disadvantage compared to the other kids." Parents should follow the American Academy of Pediatrics recommendation, which is no TV for children under 2, Zimmerman said. "Personally, I feel the cutoff should be children under 3, because there is just not any good content for children under 3."
J) One expert believes that TV can have both positive and negative effects, but it all depends on what children are watching. "Content matters," said Deborah L. Line barger, an assistant professor at the University of Pennsylvania, who co-authored an accompanying editorial. "Educational content has been found to be related to performance on school readiness tests, higher grades when they are teen-agers, whereas, non-educational content tends to be associated with lower academic performance."
K) Another expert agrees. "TV watching takes up space that could be used by more useful things," said Dr. Christopher P. Lucas, a clinical coordinator at the Early Childhood Evaluation and Treatment Program at the New York University Child Study Center. "TV is not necessarily toxic, but is some-thing that has to be done in moderation; something that balances the other needs of the child for healthy development."
L) Lucas puts the responsibility for how much TV kids watch and what they watch squarely on parents. "The amount of TV watching certainly has a link with the reduced amount of time reading or doing homework," he said. "The key is the amount of control parents have in limiting the amount of access. Get the TV out of the bedroom; be aware of what is being watched; limit the amount of TV watching."
46. According to Borzekowski, children having chances to use a family computer are likely to acquire better results on the different tests.
47. The reports issued in the Archives of Pediatrics & Adolescents Medicine find that watching too much TV leads to poor performance in school.
48. Watching more than three hours of TV before age 3 has bad effect on kids.
49. According to the second report, the chance for one to acquire a college degree depends on the amount of his TV watching during childhood.
50. In Deborah L. Lingbarger's opinion, educational content is helpful for teenagers to get better results on school readiness tests.
51. The environment of family media greatly affects children's test scores according to the first report.
52. Borzekowski believes that TV's negative effect on children's marks may mainly lie in what children watch on TV and how much time they spend on it.
53. Lucas thinks parents should take the responsibility to supervise kids' TV watching.
