Research that used advanced brain-mapping techniques appears to confirm long-held theories that TV violence has palpable effects on children, the San Antonio Express-News reported Sept. 23. For the study, scientist John P. Murray, a professor of developmental psychology at Kansas State University, conducted neuroimaging on boys and girls ages 8 to 13. The studies were conducted at the University of Texas Health Science Center. The participants watched six video clips, some very violent, while secured inside an MRI scanner for 30 minutes. According to Murray, when the children viewed the violent clips, the amygdala on the right side of the brain, which senses danger and prepares to react to it, lit up. In addition, the right posterior cingulate of the brain, which is reserved for long-term memory of important or traumatic events, also showed activity. Murray said the findings suggest that children who watch violent television shows are more likely to treat others in an aggressive manner, become less sensitive to suffering, and tend to be more fearful of the world around them. |
