Document Summary

Can"t get to statement because it is correlational: experiment: between groups design, exposure to tv violence, length of exposure, different type of violence, control group no tv watching, However: watching a lot of violence may desensitize yourself to it. Group #1 (independent) watch violent show measure aggression (dependent) Group #2 watch non violent measure aggression. Group #3 watch no tv measure aggression. Within groups design, all groups are exposed to all shows. Counter balance: order of shows matters must switch order of shows around. Physical attack: aggression machine, electrical shock to other person. Safe attack : how hard people punch inflatable dolls. Cues to aggression: when aggression and see a cue to aggression you are more likely to act out. Internal validity degree to which experiment support causal conclusion. External validity degree to which results can be generalized. Cues in experiment convey hypothesis to participants.
