RCT: video games can hamper reading and writing skills in young boys by displacing other activities

I grew up in the days of the SNES and the Sega Megadrive. Even then, furious debates would rage about the harm (or lack thereof) that video games would inflict on growing children. A few decades later, little has changed. The debate still rages, fuelled more by the wisdom of repugnance than by data. With little regard for any actual evidence, pundits like Baroness Susan Greenfield, former Director of the Royal Institution, claim that video games negatively “rewire” our brains, infantilising us, depriving us of our very identities and even instigating the financial crisis.

Of course, the fact that video games are irrationally vilified doesn’t mean that they are automatically harmless. There’s still a need for decent studies that assess their impact on behaviour. One such study has emerged from Denison University, where Robert Weis and Brittany Cerankosky have tested what happens when you give young boys, aged 6-9, a new video game system. 

They found that after 4 months, boys who had received the games had lower reading and writing scores than expected, failing to improve to the same degree as their console-less peers. They also faced more academic problems at school. At first this might seem like support for the rewired brains of Greenfield’s editorials, but the reality is much simpler – the games were displacing other after-school academic activities. While some children were finishing their homework or reading bedtime stories, those with games were mashing buttons.

There is much to like about Weis and Cerankosky’s study. For a start, it is a randomised controlled trial (RCT), one of the most reliable ways of finding out if something is truly causing a specific effect. Indeed, it is the first such trial looking into the effects of video games on the academic abilities and behaviour of young boys.
