Where it stands

Researchers in Finland began tracking children's screen time eight years ago. They expected to find negative effects on brain development. Instead, they found that children who spent more hours on screens showed better cognitive processing as teenagers. The study has sparked significant interest.

EMJ, JO24, HuffPost UK, U.S. News & World Report and Space Daily have all covered the findings. The European Medical Journal and HuffPost UK have noted that the study suggests potential benefits of screen time for cognitive development. The Journal of 24 has focused on the surprising nature of the results, while U.S.

News & World Report has emphasized that screen time is not entirely detrimental. The researchers have not yet disclosed plans for follow-up studies. The children in the study are now teenagers. Coverage does not yet specify whether the researchers plan to continue tracking their development into adulthood.
