Document Summary
We were going to permanently damage children by allowing them access to violent and inappropriate content in music. If you view the shows a lot, children were more pro-social. Less prejudice, less racism if they watched it. Some kids watch 30 hours of tv: families: low monitoring of what children are doing. How violent is tv: violence people get rewarded for coyote and road runner, research investigates: Immediate effects: violent behaviour following watching these shows. Longitudinal effects: does(cid:374)"t allo(cid:449) us to (cid:373)ake (cid:272)ausal state(cid:373)e(cid:374)t all correlational. Iv1: exposure to violent behaviour (live vs. film vs. cartoon vs. no exposure) Iv2: consequences to model (reward vs. punishment: dv1: aggression (generally, dv2: imitative aggression, model rewarded: boys higher than girls, model punished; lower than reward but boys still significantly higher than girls. Children learn new aggressive behaviours by watching them be: modeled, rewarded. Effect of power rangers on aggression in the playground (boyatzis et al. , 1995)
