研究发现儿童经常使用社交媒体注意力会逐渐下降

Core Findings - A study conducted by Karolinska Institute indicates that children who frequently use social media show a declining trend in attention over time, unlike other screen activities such as watching TV or playing computer games, which do not exhibit similar associations [1][2] - The research involved 8,324 children aged 9 to 10 years in the U.S. and tracked them over four years, assessing their social media usage and attention levels [1] Social Media Usage Trends - The average daily time spent on social media by children significantly increases with age, from approximately 30 minutes at age 9 to about 2.5 hours by age 13 [2] - The study found a significant correlation between social media usage and declining attention in children, while no similar correlation was found with TV watching or gaming [2] Implications of Findings - Researchers suggest that the rapid content switching and constant notifications associated with social media may impair the brain's ability to maintain focus, potentially explaining the observed decline in attention [2] - The findings do not imply that all children using social media will experience attention issues, but they highlight the need for further discussion on age limits and platform design [2] - The research team plans to continue tracking the children's development beyond age 14 to assess whether the association between social media use and attention changes persists [2]
