How Video Games are Bad for Your Brain

Beware of the what video games are doing to your brain, or to the brain of your child!

In Nicholas Carr’s book Utopia is Creepy, he has a chapter called ‘Grand Theft Attention’, where he reviews the latest research on video games and the brain. The chapter is a reprint of his 2011 blog post ‘Grand Theft Attention: video games and the brain.’

A 2009 study by a different group of Iowa State researchers, published in Psychophysiology, investigated the effects of video-gaming on cognitive control, through experiments with 51 young men, both heavy gamers and light gamers. The study indicated that video-gaming has little effect on “reactive” cognitive control – the ability to respond to some event after it happens. But when it comes to “proactive” cognitive control – the ability to plan and adjust one’s behavior in advance of an event or stimulus – video-gaming has a significant negative effect. “The negative association between video game experience and proactive cognitive control,” the researchers write, “is interesting in the context of recent evidence demonstrating a similar correlation between video game experience and self-reported measures of attention deficits and hyperactivity. Together, these data may indicate that the video game experience is associated with a decrease in the efficiency of proactive cognitive control that supports one’s ability to maintain goal-directed action when the environment is not intrinsically engaging.” Video gamers, in other words, seem to have a difficult time staying focused on a task that doesn’t involve constant incoming stimuli. Their attention wavers.
