      American children and teenagers have increased their use of entertainment media by more than one hour
a day in the last five years. On an average day they now spend seven and a half hours using media.
     These are the findings of a new survey. It included not only devices like TVs, computers, mobile phones
and MP3 players, but also media like books and magazines. It did not count media use for school.
     Vicky Rideout at the Kaiser Family Foundation, a health re- search group, wrote the report. She was
surprised that kids could fit even more media time into their day.
     She found that they spent ten hours and fortyfive minutes if you counted each device individually. But
children multi-task a lot, and Vicky Rideout says this is not necessarily a good thing. "
     People who study the brain will tell you that you can't actually multitask in that way. You're really
switching back and forth in order from different tasks, just doing it rapidly, and that you don't really do either
task as well as you would do them if. you did them one at a time." she added.
     The study suggests a link between heavy media use and lower performance in school. About one-fourth of
those who used media the least reported that their grades were mostly average or below. But that was true of
half the heavy media users.
     So where are the parents? Children who had any rule limiting the use of any kind of media were exposed to
an average of about three hours less media a day. But only one-third of children had to follow any rules.
     Girls spent more time than boys on social networking sites, lis tening to music and reading. Boys spent
more time on video games-an average of forty eight minutes more a day than girls.
     Vicky said "It looks like the girls just sort of lose interest in the games and they drop off and start doing
other things, whereas the boys' interest remains strong."
     Some other findings: Time spent reading books has not dropped in the last five years. But time with
newspapers and magazines has, though some reading now takes place online.
