More than 100 adults between the ages of 17 and 25, half of whom were diagnosed with autism spectrum disorder, participated in the study.
After playing one of two video games that differed only in the amount of violence present in the game, participants engaged in a task to measure aggression. In that task, participants were led to believe they were competing against another person in a trial to test their reaction times. If the participant won the trial, he or she could “blast” their opponent with a loud noise. The length and volume of that noise were determined by the participant, which allowed the researchers to measure aggression levels in the participants.
The results indicated that the amount of violence in the game made no difference in how participants with ASD responded; that is, participants who played the more violent game did not show more “aggressive” responses than those who played the less violent game.
“If violent video games caused adults with autism spectrum disorder to behave aggressively, we should have seen some evidence of this in our study, but we did not,” Engelhardt said in a statement from the University of Missouri.
The researchers also found that the violent video games did not affect participants with autism spectrum disorder differently than typically developing participants.
“There are some caveats to our findings,” Engelhardt explained. “For example, we only exposed participants to violent or nonviolent games for 15 minutes before measuring their willingness to behave aggressively. This study, therefore, cannot speak to the potential long-term effects of violent video game exposure.”
Engelhardt and colleagues hope that other researchers will attempt to replicate these findings, using similar experimental methods.
“Although preliminary, we hope that these findings help to correct faulty assumptions among the general public and that they will inform our ongoing understanding of a clinically relevant topic,” the researchers conclude.
