Presumably, watching violent video games induces desensitization to violent imagery. What does desensitization mean? How was a neuroscientific approach used to study this desensitization? What may one reasonably infer from these data?
What will be an ideal response?
Desensitization means people don't find violence in media, or even actual violence, as disturbing as they would otherwise find it. Participants were chosen who had a history of playing either violent or nonviolent video games. They viewed either violent or nonviolent photographs while P300 event-related potentials were recorded. Smaller P300 potentials indicate a less disturbed response to an image. Those who had previous histories of viewing violent material did, in fact, show smaller P300 potentials. That is, they were desensitized to the violent photographs they viewed while being recorded. This suggests that continued viewing of violent video games actually has a long-term effect on the brain. Such desensitization has been shown to predict the likelihood of aggressing against others.
