Document Summary
Long-term effects of media violence: longitudinal studies support the view that watching violence leads to aggression. Preference for violence in 3rd grade predicted aggression 10 years later. Violent tv watching by 1st and 3rd graders predicted violence 15 years later after controlling for childhood aggressiveness and parental factors. Meta-analysis: of video game violence studies found: Aggressive models increase aggressive behaviour among children and adults. Influences values and attitudes towards aggression, through habituation become desensitised to violence. Depictions of violence can change values and attitudes through cultivation, media influenced belief that the world is a dangerous place. Early research is encouraging, positive effect associated with prosocial tv shows and children"s prosocial behaviour. Some games feature positive, helpful, cooperative behaviours. Pornography and sexual aggression: little support for direct causal link between pornography use in general and sexual aggression. Type of pornography may make a difference: Non violent, domesticated porn is enjoyed by 81% of men and 66% of women.
