Eliza designs an experiment because she believes that watching violent movies makes people more aggressive. she tests aggressiveness after having participants watch 30 minutes of a violent action movie versus a nonviolent action movie. her dependent variable in the violent condition asks, "do you feel more violent and aggressive after watching this violent and aggressive movie? "

It hasn't been demonstrated that violent movies make for violent behaviour. Usually, if a person has violent traits, he tends to look for violent movies but there's has to be a pre-determined condition or a violent past involved. A violent movie may trigger that aspect of the person, but if he doesn't have an specific disorder I don't think a violent movie can make a difference because we can distinguish of what is real and what is not. People with violent disorders usually don't know how to differentiate what's real and what's fiction.

you so !
