Oh no! If chatty Kathy is constantly talking with you at your desk you are ACTUALLY losing brain activity.

Carnagie Mellon University out of Pittsburgh did the study. Now, what's important to remember is that you are only dumber while you are distracted. You don't remain so dumb.

However the research showed that while you are distracted that you become about 20% more stupid than when you were working. The longer you remain distracted the more dumb you get.

The study also showed that you only get about 11 minutes worth of work done in between distractions. They also found that it takes at least a 1/2 hour to regain focus after a distraction.
