Finnish study finds more childhood screen time associated with better adolescent cognitive processing
↗
A Finnish study found that children who accumulated more screen time growing up tended to show better cognitive processing during adolescence, with researchers suggesting the type of screen activity matters more than total duration.
The study challenges the assumption that screen time is inherently harmful to children's cognitive development, suggesting that active, problem-solving digital engagement may support cognitive processing. For anyone building educational or creative software for children, this provides evidence that well-designed interactive digital experiences could have cognitive benefits rather than simply being a trade-off.

Children who accumulated more screen time as they grew up tended to show better cognitive processing during adolescence, contrary to common assumptions.
The type of screen activity matters, with active thinking, problem-solving, creativity, and learning potentially explaining the positive association.
Physical activity relationships with cognition were gender-specific and complex, and device-measured physical activity showed no association with cognitive processing.
