films and TV

• Meta analyses

  • Bushman and Huesman (2006) found significant effect sizes for exposure to media violence on aggressive behaviours, aggressive thought, angry feelings and arousal level
  • Short term effects of violent media were greater for adults than children
  • Long term effects were greater for children than adults
• Longitudinal studies

  • Huesman et al (2003) studied children between the ages of 6-9, and then again 15 years later. Habitual early exposure to TV violence was predictive of later adult aggression
