Quick Summary

A study by researchers at Western University found that excessive screen time in toddlers correlates with reduced brain volume in areas associated with language development and poorer language skills. The Canadian Paediatric Society recommends no screen time for children under two years old, and less than one hour daily for those aged two to five, but fewer than half of Canadian children meet these guidelines. Dana Infald, an early childhood educator, observed that toddlers who used screens had shorter attention spans and weaker language development compared to their screen-free peers.

Story summary

A recent study from Western University suggests that excessive screen use among young children can negatively impact their language development. The research indicates that toddlers who spend more time with screens have reduced brain volume in the area associated with language skills, leading to poorer language abilities. Early childhood educator Dana Infald in Toronto observed similar trends: children without screen exposure had stronger language development and longer attention spans compared to those with excessive screen use. This aligns with a growing body of evidence highlighting the need for policy-makers to address screens as a public health issue, particularly for young children. The study was published last week, adding to concerns previously focused on older children regarding social media and phone usage in classrooms.

Society → recommend → 2
And for children between ages 2 and 5, the recommendation is to limit screens to less than one hour a day. asserted
