ANN ARBOR, Mich.-Violent video games and movies make people numb to the pain and suffering of others, according to a research report published in the March 2009 issue of Psychological Science.

The report details the findings of two studies conducted by University of Michigan professor Brad Bushman and Iowa State University professor Craig Anderson.

The studies fill an important research gap in the literature on the impact of violent media. In earlier work, Bushman and Anderson demonstrated that exposure to violent media produces physiological desensitization-lowering heart rate and skin conductance-when viewing scenes of actual violence a short time later. But the current research demonstrates that violent media also affect someone's willingness to offer help to an injured person, in a field study as well as in a laboratory experiment.

"These studies clearly show that violent media exposure can reduce helping behavior," said Bushman, professor of psychology and communications and a research professor at the U-M Institute for Social Research.

"People exposed to media violence are less helpful to others in need because they are 'comfortably numb' to the pain and suffering of others, to borrow the title of a Pink Floyd song," he said.

In one of the studies, 320 college students played either a violent or a nonviolent video game for approximately 20 minutes. A few minutes later, they overheard a staged fight that ended with the "victim" sustaining a sprained ankle and groaning in pain.
