Kids who check their phones all the time at school have poorer self control
A new international study has revealed a concerning link between frequent smartphone checking and diminished self-control among school-aged children. The research suggests that students who repeatedly pick up their phones during the school day tend to perform worse on self-control tests—measures often associated with the ability to pay sustained attention in the classroom—than peers who check their phones less frequently. Importantly, the study highlights that it is the frequency of phone checking, rather than total screen time, that is most strongly correlated with self-control issues.
In this study, researchers analyzed smartphone usage data from 79 children and teenagers aged between 11 and 18. They discovered that children were consistently using their phones throughout the entire school day, and none of the monitored hours were completely phone-free. On average, students spent approximately 2.22 hours of the school day actively engaged with their screens. Remarkably, individual students checked their phones nearly 65 times per day on average. The study found a clear pattern: the higher the number of phone checks, the poorer the students performed on cognitive tasks designed to assess self-control.
Self-control is a critical component of children’s academic success and overall mental health. It involves the capacity to regulate impulses, focus attention, and persist in challenging tasks. In classroom settings, strong self-control is essential for maintaining attention, following instructions, and managing distractions. The implications of reduced self-control due to frequent smartphone interruptions may, therefore, be profound. Students with weaker self-control might find it more difficult to engage fully with lessons and absorb information, potentially undermining their academic performance.
However, the researchers caution that the current findings do not establish causality. It remains unclear whether frequent smartphone checking is causing declines in self-control, or whether children with naturally poorer self-control are more inclined to repeatedly check their phones. This distinction is significant for parents, educators, and policymakers in designing interventions. Rather than focusing solely on reducing overall screen time, which has been the traditional approach, these findings suggest that managing the frequency of phone checking—or “checking behaviors”—may be a more effective strategy. Excessive fragmenting of attention by frequent phone use could be a key factor to target.
This insight also raises questions about modern digital environments and their impact on young people’s cognitive development. Smartphones provide instant gratification and constant notifications, making it tempting to reach for a device multiple times during periods that might otherwise be used for concentration. Understanding how to help children develop healthier smartphone habits could, therefore, prove critical for supporting their educational outcomes and wellbeing.
Why this matters
As smartphones become increasingly integrated into daily life, especially among younger generations, concerns about their impact on mental health, academic achievement, and social relationships have grown. This study contributes to the growing body of evidence that smartphone use is nuanced: it is not just about how long children use these devices, but how often they disrupt their focus through frequent checking. Given the widespread adoption of mobile technology in schools and at home, educators and parents face the challenge of balancing the benefits of digital tools with the possible cognitive costs tied to distraction and self-control.
By zeroing in on phone-checking frequency, schools may develop targeted policies—such as designated phone-free times or teaching self-regulation strategies—to help students build better attention skills. Ultimately, a better understanding of the dynamics between smartphone behavior and self-control could foster environments that support healthy technology use while safeguarding children’s academic and personal development.
FAQ
Q1: Does total screen time not matter for self-control?
A1: According to this study, total screen time during the school day was not the strongest factor linked to self-control scores. Rather, it was how often students checked their phones—the number of times they interrupted their focus—that was more closely correlated with reduced self-control abilities.
Q2: Can limiting phone use improve self-control in students?
A2: The study does not establish a direct causal relationship, so it is unclear whether limiting phone use will improve self-control. However, interventions focused on reducing the frequency of phone checking, rather than just overall screen time, may be more effective. Further research is needed to determine best strategies.
Q3: How can parents and schools help manage smartphone checking behaviors?
A3: Parents and schools can encourage phone-free times during lessons, promote awareness of distraction effects, and teach self-regulation and attention skills. Creating structured environments that minimize unnecessary phone notifications and opportunities for frequent checking can also help students maintain focus.
