Recently my research team observed nearly 300 middle school, high school and university students studying something important for a mere 15 minutes in their natural environments. We were interested in whether they could maintain focus and, if not, what might be distracting them. Every minute we noted exactly what they were doing, whether they were studying, if they were texting or listening to music or watching television in the background, and if they had a computer screen in front of them and what websites were being visited.
The results were startling. First, these students were only able to focus and stay on task for an average of three minutes at a time and nearly all of their distractions came from technology.
[By the way, other researchers have found similar attention spans with computer programmers and medical students.] The major culprit: their smartphone and their laptop were providing constant interruptions. We also looked at whether these distractors might predict who was a better student. Not surprisingly those who stayed on task longer and had study strategies were better students. The worst students were those who consumed more media each day and had a preference for working on several tasks at the same time and switching back and forth between them. One additional result stunned us: If they checked Facebook just once during the 15-minute study period they were worse students. It didn’t matter how many times they looked at Facebook; once was enough.
