The study was conducted by National University of Singapore researchers Don J.Q. Chen and Vivien K.G Lim. They gave students a task of highlighting the letter "e" in sample text for twenty minutes, then in the next ten minutes a control group of students were given a different simple task. Meanwhile, another group was allowed to do everything except surf the web during that break, and a third group could surf the web. Then all three groups went back to highlighting the letters.
The result, as you've guessed by now, is that the web surfers:
were significantly more productive and effective at the tasks than those in the other two groups and reported lower levels of mental exhaustion, boredom and higher levels of engagement.
