Gary W. Giumetti and Patrick M. Markey from Villanova University attempted to quantify whether or not violent games increase aggression without an increase in anger. While this is not a new endeavor, it is interesting to say the least.

The tests conducted, which involved 79 females and 88 males, measured aggression and the results were used to test for correlations among anger, violent games, and aggression. The procedure was relatively simple. Each individual was given three incomplete scenarios and they were requested to provide 20 responses on their actions if they were involved. Those who played violent games was conclusively more aggressive by a small margin.

By a small margin, we meant that those who played violent games had nine out of the 60 responses scored as aggressive. Those who played non-violent games scored seven. It has been noted that the reactions are common to any individual exposed to violent media. The people who conducted the study even went so far as to note that it is similar to another study that put people in a hot room. Yes, a similar rise in aggression was present in that study as well.

The scores were correlated with long-term anger, and individuals who were generally calm were largely unaffected by their exposure to violent media. On the other hand, those who were labeled as "angry" showed an increase in their aggression when exposed to violent games.

The results appear to show that the correlation between aggression and violent video games depends on the mental state of the individuals involved. This is not surprising news, but something those who would either defend or attack violent video games should take notice.
