  • research into video games and aggression
    • experimental studies
      • gentile and stone found a short term increase in levels of physiological arousal,hostile feelings and agressive behaviour following sessions of violent games compared to sessions of non-violent game play
      • arousal is measured by bloodpressure and heart rate where as hostile feelings are measured by self report
      • anderson and dill found that students participants blasted their opponents with white noise for longer and rated themselves higher on the state hositility scale after playing wolfenstien 3D (violent shotter game) compared to those who played myst (puzzle game)
    • longitudinal studies
      • ihori did a study of 800 japanese 9-10 year olds were surveyed twice during a school year they found that the amount of video games play at time one was significantly related to later physical agression but agression at time one was not related to later video game play
      • anderson et al studied 430 7-9 year olds were surveyed at two points during the school year children who had high exposureto violent video games became more verbally and physically agressive and less prosocial
        • this study suggests that repeated exposure to violent video games not only increases agressive behaviour but also decreases prosocial helpful behaviours
    • correlation studies
      • gentile nd anderson invovling over 600 adolescents found that time spent playing violent computer games associated with agressive fellings and arguments with teachers and a greater incidenceof physical fights
        • even children with lower levels of trait hostility who spent more time playing violent video games were more likely to get into physical fights than children with high levels of trait hostility who played fewer violent games
    • meta analysis
      • several meta analysis have found a consistent link between violent games and agressive behaviour this appears to hold for both children and adult
