Terry Judd, a professor at the University of Melbourne, monitored more than 3,300 computer session logs from 1,229 students studying in the computer lab and found that the average time on task was only 2.3 minutes; multitasking was the name of the game, with less than 10 percent of the sessions being devoid of task switching to something other than studying, which turned out to be primarily checking email, texting, and social media.
