 This research suggests that children have difficulty concentrating on text displayed on a computer screen as opposed to text displayed on paper. This is because the screen reading requires more effort than the paper reading, which is reflected in the increased theta waves in the brain. Additionally, this research shows that the amount of concentration required for screen reading correlates negatively with accuracy on a test designed to measure attention and positively with performance time.
