Researchers claim that children who watch television for long hours are more likely to be agitated.The research was carried out by Jeffrey Johnson, of Columbia University and the New York State Psychiatric Institute. His team tracked more than 700 children through adolescence to adulthood.
They found that those who had watched one or more hours of television a day appeared much more likely to get into fights or behave aggressively towards other people later in life. Only 5.7% of the adolescents who watched less than an hour of television a day consigned aggressive acts in later years, compared with 24% of those who watched between one and three hours, and 30% of those who watched more than three hours a day. This study is being disputed by British experts.
