The background, aim, and method.

Previous research had indicated that violence on TV produces an increased tendency towards aggressive behaviour in children, most had male participants. Video games large role in children’s leisure time – TV watchers passive whereas video games are active. Furthermore, the aim was to investigate whether computer-generated games depicting a lot of violence affected children and whether they affected boys and girls differently. The method was a laboratory experiment with an independent measures design. The independent variables was whether participants were placed in the high aggression, low aggression or control group. (Participants only took part in one condition). Or, whether participants were players or observers. (Participants were either player or observer, not both).
