Research results show that 'children who play games longer than average have higher intelligence'
Many of you may have been told when you were a kid that 'playing too many games makes you sick,' but a new study of more than 5,000 children said, 'Longer than average time.' Children who play games are more intelligent than other children. '

Video games: our study suggests they boost intelligence in children
Today's children spend a very long time playing games, smartphones, TVs, etc., and many adults are concerned about the impact of screen time on their children. Therefore, research teams at the Karolinska Institute in Sweden and the Free University of Amsterdam in the Netherlands conducted research to investigate 'the effect of screen time on children's intelligence.'
In this study, the research team used data from the Adolescent Brain and Cognitive Development Project , a longitudinal study of American children. The survey asked more than 5,000 children screen times at age 9 or 10 and conducted a test to measure their intelligence. Two tasks to measure reading comprehension and vocabulary, a task to measure attention and executive function, a task to measure visual spatial processing ability, and a task to measure learning ability were used to measure intelligence. that's right. And two years later, he measured the intelligence of the children again and investigated how much the intelligence fluctuated.
Another feature of this study is that it 'considers genes and socio-economic background.' There have been studies on screen time and intelligence so far, but few have considered socio-economic backgrounds, and no studies have considered genetic effects. 'Genes are important because intelligence is so hereditary . If these factors aren't taken into account, they may obscure the true impact of screen time on children.' I point out that.
The survey found that as of 2017, children aged 9 or 10 spend an average of 4 hours a day, and the top 25% spend more than 6 hours a day on screen time. The breakdown was an average of 2 hours and 30 minutes for watching online or TV videos, an average of 30 minutes for social media, and an average of 1 hour for video games.
When we looked at the relationship between these screen times and intelligence at age 9 or 10, we found that video viewing and social media were associated with lower-average intelligence, and games were not associated with intelligence. However, as a result of comparing these relationships with intelligence after 2 years, it was found that children who played more games at the age of 9 or 10 had better than average intelligence after 2 years for both men and women. For example, children who were in the top 17% of time playing games had an IQ 2.5 percentage points higher than average two years later, the research team said.
On the other hand, social media was not related to intelligence improvement, and watching videos was not related to intelligence when 'parental education' was taken into consideration. 'This is evidence that video games have a beneficial causal relationship to intelligence,' the research team said, but this study did not consider mental health, sleep quality, physical exercise, etc. He pointed out that not all parents should allow their children to play games indefinitely, as there are many aspects to this.
