Violent video an unreal villain

Shooting massacres and other social violence are blamed, unscientifically, on video games, say experts.

The number of aliens you kill may directly contribute to an improvement in your brain. This may not sound like a typical scientific discovery, but it has come from some of the world’s finest neuroscience laboratories.

It’s the genuine outcome of studies on how action video games can improve your attention, mental control and visual skills.

We’re talking here about fast-moving titles such as Halo, Call of Duty and Grand Theft Auto, which demand quick reflexes and instant decision-making.

They’re often portrayed as the most trashy, vapid and empty-headed forms of digital entertainment, but they may be particularly good at sharpening mental skills.

This may come as a surprise if you read much of the popular press, which is often obsessed with technological scare stories.

Scientific evidence has been considerably more convincing. There are numerous studies on how playing action computer games, as opposed to puzzle or strategy titles such as The Sims or Tetris, leads to an improvement in how well we pay attention, how quickly we react, how sensitive we are to images and how accurately we sort information.

Crucially, these studies are not just focussed on people who already play a lot of video games, but are testing whether action video game training genuinely leads to improvements.

The studies use randomised controlled trials. A group of people are randomly assigned to one of two groups.

Half get the “treatment”, perhaps blasting away at enemy combatants in Medal of Honor, while the others get the “placebo” — for example, managing a digital family in The Sims 3.

Reliably, those assigned to play the fast-moving action games show improvements on neuropsychological tests that measure the ability to process quickly and react to visual information.

These conclusions were temporarily thrown into doubt in 2011 when several scientists, led by Walter Boot from Florida State University, suggested these findings were due to poor experimental design, but better planned studies have continued to find a positive effect.

Another aspect of the game debate concerns the impact of violent video games. This has become a matter of public anxiety again in light of the tragic Sandy Hook school killings in the US after the gunman was found to be a fan of first-person shooter games such as Call of Duty.

But this is not a good basis for science, simply because the sheer popularity of this form of entertainment makes it difficult to attribute any form of link between their use and statistically rare individuals. Nonetheless, it has been researched fully.

Also using randomised controlled trials, research has found violent video games cause a reliable short-term increase in aggression during lab-based tests. However, this seems not to be something specific to computer games.

Television and even violence in the news have a similar impact. The longer-term effects of aggressive gaming are still not well studied, but we would expect similar results from long-term studies of other violent media — again a small increase in aggressive thoughts and behaviour in the lab.

These, however, are not the same as actual violence. Psychologist Christopher Ferguson of Texas A&M International University has examined what predicts genuine violence committed by young people.

It turns out that delinquent peers, depression and an abusive family environment account for actual violent incidents. Exposure to media violence seems to have only a minor and usually insignificant effect.

This makes sense even in light of horrifying mass shootings. Several of the killers did play video games, but this doesn’t distinguish them from millions of non-violent young men. Most, however, had a previous history of antisocial behaviour and a disturbed background, something much more common in killers.

Perhaps the most telling effect of video games concerns not what they involve but how much time someone spends playing them.

A helpful study on the effect of giving games consoles to young people found that, while the gaming had no negative impact on core abilities, school performance declined for those kids who put aside homework for screen entertainment.

Similarly, a significant amount of research has found that putting aside exercise for the physical inactivity of video games raises the risk of obesity and general poor health.

And while “addiction” is now the pop psychology label of choice for anything that someone does to excess (sex, video games, shopping), the same behaviour could just as easily, and more parsimoniously, be described as a form of avoidant or unhelpful coping.

Rather than dealing with uncomfortable life problems, some people avoid them by absorbing themselves in other activities, leading to an unhelpful cycle where the distractions end up maintaining the problems because they’re never confronted. This can apply as easily to books as video games.

The verdict from science:
Video games are a new and ominous threat to society but that anything in excess will cause us problems.

The somewhat prosaic conclusion is that moderation is key — whether you’re killing aliens, racing cars or trying to place oddly shaped blocks that fall from the sky.
