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.
"Although no single research project is definitive, our research aims to provide the most current and compelling responses to key criticisms on this topic. Based on our findings, we feel it is clear that violent video game play is associated with subsequent increases in physical aggression," said lead author Jay G. Hull, the Dartmouth Professor of Psychological and Brain Sciences, and associate dean of faculty for the social sciences at Dartmouth.
