flag Low social media use by preteens linked to lower cognitive scores in early adolescence, per JAMA study.

flag A new study in JAMA links even low levels of social media use among preteens to lower reading and memory test scores in early adolescence. flag Analyzing data from over 6,000 children in the ABCD Study, researchers found that those using social media for about an hour a day by age 13 scored 1 to 2 points lower on cognitive tests, while those using three or more hours daily scored up to 4 to 5 points lower than non-users. flag The effect appears dose-dependent, with small differences potentially signaling long-term learning gaps. flag While the study does not prove causation, experts say it adds to concerns about how digital habits may affect attention and academic performance, especially as use rises in later adolescence.
