Watching violent TV or video games may promote more aggressive behavior in teens – 1
Narrator: This is NIH Health Matters. I’m Joe Balintfy. Watching violent movies or TV shows, or playing violent video games, desensitizes teenagers and may promote aggressive behavior. Dr. Jordan Grafman at the National Institute of Neurological Disorders and Stroke, explains research shows that in boys exposed to more violent videos, activation in their brain regions concerned with emotional reactivity decreased over time.
Grafman: Those areas of the brain in essence became desensitized to the aggressive video clips we showed people.
Narrator: Dr. Grafman recommends limiting the frequency and the intensity of exposure to aggression. For more information on this research, visit www.ninds.nih.gov. Health Matters is produced by the National Institutes of Health, part of the U.S. Department of Health and Human Services.
