A new study has found that boys exposed to violent screen time during preschool years are more likely to become antisocial and violent by adolescence. Researcher Linda Pagani, who led the 11-year study, says early exposure to violent content can have serious and lasting consequences for young males. The study, which analyzed data from over 1,000 children in Quebec, found that boys who were exposed to violent media at a young age were more likely to exhibit aggressive behavior by age 15.
