Abstract
Research suggests that prolonged daily screen use is associated with cognitive fatigue. This study examines whether the number of hours spent using digital screens daily is correlated with cognitive focus scores among remote software engineers.
Methods: Self-report screen-time logs and scores from a validated Cognitive Focus Test (CFT) were collected from a sample of 1,200 remote software engineers across several multinational tech companies.
Findings: A strong negative correlation was found between daily screen hours and CFT scores. Those with higher screen hours also reported higher caffeine consumption and fewer hours of sleep, both of which were linked to lower focus scores.
Interpretation: These results highlight the potential cognitive costs of excessive screen time. Employers could use these insights to design guidelines for screen breaks and work-life balance.
