Performed by Australia's Swinburne University of Technology across schools in Melbourne, the project analyzed behavior of 120 children aged 11 to 15 before and after a 20 minute session of id Software's Quake II. Following their time with the violent first person shooter, a majority of the test subjects displayed no evidence of the game affecting their mood or behavior. However, those with a tendency for worry, neurotic behavior and or violence did show an increase in aggressive behavior.

The children that experienced a shift in behavior "were a little bit more aggressive anyway in their interaction with life," noted Swinburne professor Grant Devilly. "For the rest of kids, the vast majority, it [violent game play] makes no difference at all in their general aggression rate."

Devilly's statements and findings challenge a 2006 study from the Radiological Society of North America, which found that violent video games cause more "emotional arousal" than nonviolent interactive experiences.
