Cell Phone Ownership Linked to Lower Reading Scores in Elementary Students

Elementary school students who own personal cell phones tend to have lower reading comprehension scores than those who do not, according to a study by UCLA psychologists. The research, published in the journal Behavioral Sciences, indicates that the negative correlation is tied to the status of ownership rather than the immediate presence of a device during school hours.

Led by Professor Patricia Greenfield, the study analyzed 3rd and 6th grade students from a diverse group of Antelope Valley public schools and Coptic Church schools in Los Angeles County. The researchers found that the presence of a phone at school—whether the device sat on a student's desk or remained out of sight—had no impact on reading comprehension scores. Instead, the deficit was consistently linked to whether the child owned a phone at all.

The ownership gap

The study aimed to determine if cell phones interfere with the deep concentration required for academic testing, filling a gap in experimental research specifically targeting elementary-aged children. The results suggest that the cognitive or behavioral effects of owning a device at a young age are more significant than the momentary distraction of a notification in class.

"We found that there's no age at which you can give a child a phone that's better or worse for reading comprehension, so it's just having a phone at all," said Patricia Greenfield. She further clarified that "it's ownership of a phone, not the immediate presence of one, that correlates with poorer reading comprehension at the elementary school level."

Implications for school policy

These findings challenge the prevailing assumption that school-based phone bans are a primary solution for improving academic performance. Because the reading deficit is linked to the broader habit of ownership, simply removing devices from the classroom may not directly improve reading scores. While the researchers noted that such bans may still provide benefits for a student's social development, they are unlikely to reverse the comprehension trends identified in the study.

Shifting the conversation

This research shifts the educational debate from "classroom distraction" to the long-term cognitive implications of early device ownership. By decoupling the act of owning a phone from the act of using one in class, the study suggests that the influence of mobile technology on literacy begins well before a student enters the school gates.

Moving forward, educators and parents may need to look beyond restrictive school policies to understand how early access to personal technology shapes the way children process and comprehend written information. Whether this correlation is causal or a symptom of other behavioral patterns remains a key area for further investigation.
