The term "supertasker" is given to individuals able to successfully accomplish two or more tasks at once—a quality possessed by less than 2.5 percent of people.
A new University of Utah study on distraction in the driver's seat finds that a very small percentage of participants were able to do other things successfully while driving without a drop in performance on any task. In fact, some of these supertaskers performed better while multitasking than they did while completing the tasks alone.
