Phone pings steal 7 seconds: New study reveals distraction cost

Each smartphone notification can steal up to 7 seconds of concentration, according to a recent study published in the journal Computers in Human Behavior. The cognitive impact of these alerts is magnified by their personal relevance, as the brain is more drawn to notifications perceived as significant. Researchers utilized a Stroop task, a cognitive test measuring attention and information processing speed, to quantify this distraction.

During the study, 180 university students were divided into three groups, each experiencing slightly varied notification conditions. Results indicated that all groups faced a 7-second delay in processing information due to notifications. However, participants who believed they were receiving real personal notifications experienced a more pronounced interruption, highlighting the role of perceived relevance and learned habits.

Interestingly, the study suggests that the sheer volume of notifications and the frequency of checking smartphones are more detrimental to attention than total screen time. This pattern indicates that fragmented digital engagement significantly affects cognitive processes. Experts advise that improving digital well-being may involve reducing unnecessary interruptions rather than solely decreasing overall phone usage.

Experts also suggest that platforms for minors should silence notifications by default. For adults, electing to turn off non-essential notifications can significantly improve concentration and overall well-being, with exceptions made only for critical safety reasons.
