‘Media’ can be any form of communication channel, such as television and other entertainment channels. One example of media is computer games, in which the player takes an active role in influencing what happens on the screen.

Experimental studies: Bartholow and Anderson (2002) had student participants playing a violent computer game (‘Mortal Kombat’) or a non-violent game (‘PGA Tournament Golf’). They then had the opportunity to blast white noise, an unpleasant, high-frequency sound, at a non-existent opponent, using the Taylor Competitive Reaction Time Task (TCRTT). Those who played Mortal Kombat selected significantly higher white noise levels.

Correlational studies: DeLisi et al (2013) looked at 227 juvenile offenders with histories of aggressive behaviours. They used structured interviews to gather data about their aggression and their computer game-playing habits. Aggressive behaviour was found to be significantly correlated with playing violent video games. The researchers concluded there is a significant link between violent computer game-playing and violent behaviour.


Meta-analyses: Anderson et al (2010) looked at 136 studies, with varying methods, and found that exposure to violent computer games was linked to increases in aggressive thoughts, feelings and behaviours. This was true across different types of culture, and was especially true in the better-controlled studies. This strongly suggests an association between the effects of computer games and aggressive
