Study: Video Games May Boost Kids’ IQ

New research suggests that time spent playing video games might actually contribute to a small increase in children’s intelligence, challenging the common perception that gaming is detrimental to young minds. The study carefully accounted for factors like genetics and family background, finding a notable, though modest, link between more gaming and higher cognitive scores. This insight adds a valuable perspective to ongoing discussions about children’s screen time, indicating that not all digital activities have the same impact.

Scientists from institutions in Sweden, Germany, and the Netherlands analyzed data from nearly 10,000 children in the United States, all around nine or ten years old. These children reported their typical daily screen habits, which averaged two and a half hours watching TV or online videos, one hour playing video games, and thirty minutes on social media. Two years later, researchers reassessed over 5,000 of these children. They discovered that those who spent more time than average playing video games showed an IQ increase approximately 2.5 points higher than the average rise observed in the group. This intelligence measurement was based on tests assessing reading comprehension, visual-spatial processing, memory, flexible thinking, and self-control.

Interestingly, the study found that time spent watching television or engaging with social media did not demonstrate a clear positive or negative effect on cognitive abilities. This distinction is crucial, as it suggests the type of screen activity matters significantly. The research team emphasized that their work helps correct for genetic predispositions and socio-economic influences, which are often overlooked in similar studies. By controlling for these variables, the findings offer a more robust look at the potential cognitive effects of gaming itself.

The lead researcher, neuroscientist Torkel Klingberg from Sweden’s Karolinska Institute, stated the results support the view that screen time does not generally harm children’s cognitive skills and that video games may actively help boost intelligence. He was careful to note, however, that the study does not prove a direct cause-and-effect relationship. It also did not examine impacts on physical health, sleep, emotional wellbeing, or academic performance, leaving those important areas for future investigation.

This study aligns with a growing body of research pointing to potential cognitive benefits from gaming, such as improved problem-solving and hand-eye coordination. However, experts caution that conflicting reports on screen time often stem from methodological differences, including small sample sizes and varied study designs. The current research aimed to address some of these limitations by using a large, longitudinal dataset and accounting for genetic background.

Ultimately, intelligence is not a fixed trait, and its development is influenced by a complex mix of genetic and environmental factors. While this study provides compelling evidence that video games could play a positive role in cognitive development for some children, it is not a blanket endorsement for unlimited play. More research is needed to understand the full picture, including how different game genres might affect the brain and how screen habits interact with other aspects of a healthy childhood. The research team plans to continue studying how various environmental factors, including digital media use, relate to brain development during these formative years.
