In her TEDx talk, Daphne Bavelier, a brain scientist, explores the surprising benefits of video games on brain function and cognition. While video games are often criticized, Bavelier presents evidence that they can enhance various cognitive skills, particularly those related to attention and vision.Bavelier starts by noting the prevalence of video games among adults, not just children. She highlights that the average gamer is 33 years old and argues that video games are here to stay. She points out that action-packed games, often criticized for being mindless, can actually have positive effects when played in moderation.Research in Bavelier’s lab shows that action video games can improve vision, including the ability to resolve fine details and differentiate shades of gray. Contrary to the belief that screen time deteriorates eyesight, gamers often have better visual acuity and contrast sensitivity than non-gamers.Moreover, Bavelier discusses how these games enhance attention skills. Gamers are better at resolving conflicts and tracking multiple objects simultaneously. This improved attention extends to multitasking capabilities, contrasting sharply with findings about multitasking from other activities, like using multiple digital platforms simultaneously.Bavelier emphasizes that while excessive gaming is not beneficial, when used thoughtfully, video games can be a powerful tool for improving cognitive functions. Her research aims to develop games that leverage these benefits for educational and rehabilitative purposes, combining the engaging aspects of gaming with scientifically-backed cognitive benefits.
