Study Links Early Cellphone Ownership to Lower Literacy Scores

A growing body of research is raising concerns about the impact smartphones may be having on children’s literacy development. One recent study found that children who own cellphones tend to perform worse on reading assessments than their peers who do not have personal devices.
According to research led by Patricia M. Greenfield, Marola Hanna, Rocio Burgos-Calvillo, and Laura Rhinehart (UCLA) children with their own smartphones scored lower on reading tests, even after researchers accounted for factors such as family background and demographics. The study suggests that increased screen time may be replacing activities that traditionally support literacy development, including reading books, storytelling, and face-to-face conversations.
The findings add to growing evidence that excessive screen use may be affecting children’s academic performance.
More Kids Are Getting Phones at Younger Ages
According to Nationwide Children’s Hospital, many children now receive their first cellphone during the late elementary or middle school years, often between the ages of 10 and 12. Parents frequently cite safety, communication, and social pressures as reasons for providing devices at younger ages.
However, research has found that higher levels of screen media use are associated with lower academic achievement and reduced time spent on educational activities. While technology can provide access to learning resources, excessive recreational use may interfere with reading, homework, sleep, and concentration. (pmc.ncbi.nlm.nih.gov)
Harvard Graduate School of Education researchers have also noted that smartphones can create significant distractions, particularly when notifications, social media, and entertainment apps compete for students’ attention. As pediatrician Dr. Michael Rich explained, “The human brain is incapable of thinking more than one thing at a time.” Multitasking between schoolwork and phone use often results in reduced focus and retention.
Helping Kids Maintain Strong Literacy Skills
To help kids keep up with their skills, parents can establish screen-free reading times, encourage daily independent reading, and make books easily available throughout the home. Reading together, discussing stories, and modelling healthy reading habits can also help children view literacy as an enjoyable part of everyday life.
Experts also recommend whenever possible, parents should be teaching children to use technology intentionally rather than passively. Educational apps, e-books, and research tools can complement literacy development when balanced with traditional reading activities.
The reality is this: Smartphones are likely to remain a major part of children’s lives and working with them is something that parents will have to deal with. The challenge is not necessarily preventing phone use altogether, but ensuring kids are ready for them and that screens do not crowd out the reading, conversation, and learning experiences that help children become strong and confident readers.
