According to a new study from Michigan State University, just a 3 second distraction can ruin your workplace concentration. The researchers found that participants who were interrupted for just a few moments doubled their error rate on a sequence-based task. If you think it won’t hurt to take a tiny break just check your inbox or your smartphone, think again. For high concentration jobs that require a great deal of accuracy, your productivity could be seriously impacted. So, when someone asks if you “have a second” while you are trying to work on a complex task, tell them they can only have two. After that, your concentration is shot.
