    Researches have suggested that your gameplaying habits and TV watching inspire you to act out, but

those who enjoy killing people on screen disagree with the result.  "I have played the most violent games

available on the market today, "writes Mateo,   15.  "I don't go killing people or stealing cars because I

see it in a game.  My parents say that,   as long as I remember it's a game,   I can play whatever I want. "

      Despite what they say,   many scientific studies clearly show that violent video games make kids more

likely to yell,   push,   and punch,   says Brad Bushman,   a psychologist at the University of Michigan in

Ann Arbor.  Bushman and his colleagues recently reviewed more than 300 studies of video media effects

and said,   " We included every single study we could find on the topic.  Regardless of what kids say,  

violent video games are harmful. "

      TV has been around a lot longer than video games,   so researchers have more data on the longterm

effects of violent TV shows on people than they do on the effects of violent video games.  Scientists at

the University of Michigan recorded the TVwatching habits of hundreds of first and third graders in

1977.  Fifteen years later,   the researchers looked at what kind of adults these kids had become.  By

the time they were in their early twenties,   women who had watched violent shows as kids were four

times as likely to have punched,   choked,   or beaten other people as were women who didn't watch

such programs as kids.  Boys who watched violent TV grew up to be three times as likely to commit

crimes as boys who didn't watch such programs.  But that doesn't mean that everyone who watched

violent programs ended up being violent themselves.  It was just more likely to happen for some people.
