The effect that violent films and games have on our minds, and the implications for their place in society, has been a source of much heated debate. Now, a new study looks set to fan the flames even further. Several studies have found that violent media can desensitise people to real acts of violence, but Brad Bushman from the University of Michigan and Craig Anderson from Iowa State University have produced the first evidence that this can actually change a person’s behaviour, affecting their decisions to help others in need.
Using professional actors, they found that after 20 minutes of playing a violent video game, people who heard a loud fight that ended with an injury took longer to help the victim, and believed that the fight was less serious. Likewise, people who watched a violent film took longer to help an injured woman to pick up her crutches outside the cinema. In the duo’s own words, “Violent media make people numb to the pain and suffering of others.”
In the first study, Bushman and Anderson recruited 320 students under the pretence of studying their tastes in video games. The recruits played 20 minutes of either a violent video game (Carmageddon, Duke Nukem, Mortal Kombat or Future Cop) or a non-violent one (Glider Pro, 3D Pinball, Austin Powers or Tetra Madness). After playing, the recruits were left alone to fill in a questionnaire. They wrote their favourite type of video game (fighting, fantasy, skill, sports and so on) followed by over 200 questions on such games.
This massive list of questions was a red herring, designed to keep the volunteers busy. Three minutes into the time, Bushman and Anderson played a recording outside the room of two actors fighting about how one stole the other’s partner. The actors’ gender was matched to the recruit inside and the two quickly descended into a shouting match and came to blows.
