Revealed: New research proves playing video games might help make you smarter

Playing video games may make you smarter but regular exercise does not, scientists say.

Researchers found gamers scored better on memory, attention and reasoning skills compared to those who did not play video games.

Results also showed that moderate-level exercise of 150 minutes per week did not improve a person’s memory and thinking skills but instead boosted their mental health.

The team described the findings, published in an online portal called PsyArXiv, as “surprising” because they contradict the widely-held belief that exercise can improve cognition skills such as learning, attention, perception and memory.

Professor Adrian Owen, a neuroscientist from Western University in Canada, said: “People who frequently play video games, that is five or more hours per week for a single type of game, performed cognitively, on average, like people who were 13.7 years younger (who did not play video games).

“Individuals who engaged infrequently with video games, played less than five hours per week across all kinds of games, performed like people 5.2 years younger.”

Prof Owen also said those who did not meet UK health recommendations for physical activity “were twice as likely to suffer from depression and 1.5 times more likely to have a generalised anxiety disorder”.

“I was surprised that video games improved cognition, whereas regular exercise did not, in part because we have shown conclusively in the past that computerised ‘brain training’ games do not improve cognitive function.

“However, the sorts of games that frequent gamers play nowadays are quite different from consumer brain training games.

“Typically, they are highly engaging, and strategic and may enhance visual attention and processing speed, and problem-solving abilities, through intense repetition and practice.

“Any gamer also knows that these games are designed to activate the reward systems of the brain, which leads to the release of neurotransmitters like dopamine.

“This may also have long-term effects on cognitive function.

Regarding exercise not affecting cognition, Prof Owen said that was a surprise, given the World Health Organisation recommendations that moderate exercise can benefit cognition.

“However, that we only looked at the long-term effects of regular exercise so it may well be that a short burst of vigorous exercise does affect cognition - as many people report feeling ‘sharper’ after a workout.”

For the study, conducted by Prof Owen and his colleagues at the Science Museum Group in the UK, 1000 adults, aged between 18 and 87, were asked to fill in a survey answering questions about their health and lifestyle, including medical conditions, level of education, and employment status.

They also took part in brain tests that measured different aspects of cognition such as learning, attention, perception and memory skills.

Those taking part were also asked to estimate the average number of hours per week they spent playing video games within the past 12 months.

Prof Owen said the findings, in future, could “help us choose activities that promote healthy cognitive ageing”.
