Video games have often been blamed for inciting violence, from mass shootings to terrorist attacks.
The belief has been that playing violent games may have more of an effect on real-world behaviour than more passive forms of entertainment.
However, a recent study by the Oxford Internet Institute and the University of Oxford has shown that there is no link between playing violent video games and aggressive behaviour in adolescents.
While previous studies have relied on self-reported data from teenagers, this one used information from parents and carers who judged the level of aggressive behaviour in their children.
The content of the games was also classified using the official PEGI and ESRB rating systems.
Brian Lloyd and Sarah Maria Griffin discussed these findings in our weekly gaming slot.
