Negative Effects of Video Games and Computers

1. Short term increases in levels of physiological arousal, hostile feelings and aggressive behaviour after violent video game play compared to non-violent video game play. Expeimental study (5, 2, 2)
5. Longitudal. Children who had high exposure to video games became more verbally and physically aggressive and less pro-social (8, 2, 2)
6. People who are repeatedly exposed to violent video games become desensitised to violence and are less likely to show alternative response to violence in real life. If responses towards violence is missing, lead to greater amount of violent behaviour (15)
7. Even children with lower levels of trait hostility who spent more time playing violent video games were more likely to get into fights than thsoe with high trait hostility who played less violent video games (7, 3, 8)
9. Time spent playing violent video games was associated with aggressive feelings, arguments with teachers and greater incidence of physical fights. (7, 3, 8)

2. Increases physiological arousal, HR, Bp. Increases aggressive thoughts, hostile attrubution bias. Increases aggressive emotions. Increases aggressive actions. Decreases pro-social behaviour. (7)
3. Longitudal. 800 Japanese 9-10 year olds seveyed twice during a school year. Found that the amount of video games played at time 1 was related to later physical aggression but aggression at time 1 didn't relate to later violent video game play. (6, 2, 2)
4. Fosters social isolation. Women potrayed as weaker characters. Plots based on violence. Reinforces sterotypes. Confuses reality with fantasy. Lowers childrens inhibitions. Increases desensitisation (9)
8. Meta analysis. Found link between violent video game play and aggressive behaviour. Both children and adults (7, 3, 8)
