While this is the first study that specifically singled out Internet distractions, the article also points out that the study's findings are in line with similar studies that judged participants' responsiveness and attention span — especially those involving food rewards.
The study could have implications for employers; as many as half block access to alleged time-wasters like Facebook and Twitter. But now there's an argument (with proof) that these sites are actually making us better workers. Me? I agree that being able to watch funny videos (like the honey badger!), read my Twitter feed, and occasionally allow myself to be distracted helps me focus on my work. The only problem? Pulling myself away from the honey badger after just one viewing!
