Children's violent video game play associated with increased physical aggressive behavior
October 1, 2018, Dartmouth College
Violent video game play by adolescents is associated with increases in physical aggression over time, according to a Dartmouth meta-analysis published in the Proceedings of the National Academy of Sciences (PNAS).
Although most researchers on the subject agree that playing violent video games appears to increase physical aggression, a vocal minority continues to dispute this. To examine issues raised by the counterclaims on this topic, Dartmouth researchers conducted a meta-analysis of 24 studies from around the world from 2010 to 2017 with over 17,000 participants, ages nine to 19 years-old. The studies all examined how violent video game play affected changes in real-world physical aggression over time, ranging from three months to four years. Examples of physical aggression included incidents such as hitting someone or being sent to the principal's office for fighting, and were based on self-reports by children, parents, teachers and peers.
