Early screen use before age two linked to slower thinking and higher anxiety by adolescence, per long-term Singapore study.
A long-term Singapore study of 168 children found that infants exposed to screens before age two showed accelerated development in brain networks for vision and cognitive control, linked to slower decision-making by age 8.5 and higher anxiety levels by age 13.
Researchers used MRI scans and cognitive tests over more than a decade, noting that early screen use may disrupt normal brain development by promoting premature specialization.
The findings suggest that excessive screen time, especially before age two, may reduce brain flexibility and resilience, though frequent parent-child reading at age three appeared to lessen these effects.
The results support current guidelines limiting screen exposure in early childhood.
