A new study has found that children who spend more time on social media may perform worse in reading, memory, and vocabulary tests. The research shows that too much screen time might affect how young brains learn and remember things.
The study was published in the Journal of the American Medical Association (JAMA) on October 13. It looked at how kids aged 9 to 13 use social media and how it impacts their ability to focus, read, and remember. Those who used social media more often scored lower on tests compared to those who used it very little.
Social Media Use and Learning Problems
Researchers discovered a clear link between high social media exposure and lower test performance among school children.
- The study found that children who spent more time scrolling apps like Instagram, TikTok, and Snapchat showed weaker results in reading and memory.
- Students who used social media a lot scored up to 4 points lower on average than those who rarely used it.
- Kids who used social media for shorter periods also showed a slight drop — about 1 to 2 points — in their test scores.
- The findings suggest that time spent online could replace valuable learning or reading time.
This research comes at a time when hundreds of school districts have filed lawsuits against major social media companies. They argue that these apps are damaging students’ mental health and distracting them from their studies.
Study Details and Key Findings
The study’s lead author, Jason Nagata, a professor at the University of California, San Francisco, wanted to understand how social media affects children’s thinking ability.
- The data came from the Adolescent Brain Cognitive Development (ABCD) Study, which tracks thousands of young people over several years.
- The research team studied 6,554 children between 2016 and 2020.
- The kids were divided into three groups:
- No to very low use (58%) – children who almost never used social media.
- Low increasing use (37%) – children who added about one hour of social media per day by age 13.
- High increasing use (6%) – children who added nearly three hours of daily social media by age 13.
Nagata explained that even small drops in test performance could make a big difference if seen across millions of children. Over time, this could affect learning outcomes nationwide.
Why Social Media Might Hurt Learning
Experts believe social media can disrupt concentration and limit brain growth in several ways:
- It may replace time children would normally spend reading books, doing homework, or sleeping.
- The constant switching between apps and videos trains the brain to seek instant rewards, making it hard to stay focused for long.
- Too much information overloads the brain’s working memory, leaving less energy for deep thinking and problem-solving
Dan Florell, a psychology professor at Eastern Kentucky University, said that these small effects are worth watching closely. He explained that reading short posts and scrolling quickly doesn’t help children learn complex language or long-form reading skills.
What Parents and Teachers Can Do
While this study doesn’t say social media is completely harmful, it shows why balance is important. Parents, teachers, and schools can take steps to help:
- Limit daily screen time and encourage kids to read or play offline.
- Promote device-free hours at home and in schools.
- Discuss online habits openly with children to build awareness about healthy use.
Many schools are already making changes. According to Education Week, 31 U.S. states and Washington, D.C. have started to restrict or ban cellphone use during school hours. The goal is to help students improve both academic focus and mental health.
The Bigger Picture
This study adds to the growing discussion about social media impact on young people. While it doesn’t give all the answers, it highlights how digital habits can shape learning and thinking skills during critical brain development years.
As Nagata noted, “Even small changes can add up. Over time, the difference could become big enough to matter for millions of students.”
This is an important reminder that technology, while useful, should never replace real learning, reading, and human connection.
