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

By Ed Yong | February 23, 2010 9:30 am

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.

How Kenny Rogers and Frank Sinatra could help stroke patients

Blogging on Peer-Reviewed ResearchWe’re used to thinking of neglect as a lack of appropriate care, but to a neuroscientist, it has a very different meaning. “Spatial neglect” is a neurological condition caused by damage to one half of the brain (usually the right), where patients find it difficult to pay attention to one half of their visual space (usually the left).

This bias can affect their mental images too. If neglect patients are asked to draw clocks, many only include the numbers from 12 to 6, while some shunt all the numbers to the right side. When two famous neglect patients were asked to describe a familiar square in Milan, the city they grew up in, the landmarks they reported shifted depending on where they pictured themselves standing in the square. They would only report buildings to the right of their imagined position – swap the location and new buildings would suddenly come into mental view.

Patients tend to be particularly unaware of things on the left if other objects on the right are vying for their attention – this phenomenon, where only one of two simultaneously presented objects is seen, is called “visual extinction“.

Neglect is clearly a fascinating condition but also a debilitating and underappreciated one. It affects up to 60% of patients who suffer strokes on the right side of their brain, and it can hamper recovery and deny patients their independence. As such, there are plenty of researchers interested in finding ways of improving its symptoms. David Soto from Imperial College London is one of them, and he has discovered a deceptively simple way of helping neglect patients to regain their lost awareness – listen to their favourite music.

Soto was encouraged by a recent study, which found that stroke victims showed greater improvements in both memory and attention when they tuned into music than when they listened to audiobooks or worked in silence. And other studies have suggested that emotional faces are less likely to fall prey to visual extinction than less compelling images. But Soto wanted to see if the patient’s own emotional state had anything to do with their awareness. Would it be possible to reduce the symptoms of neglect simply by making patients feel happier through the medium of pleasant melodies?
