Multitasking

There has been a lot of discussion at OOTJ and elsewhere about multitasking. Like many parents, I questioned my teenagers' ability to do homework while checking email, instant messaging, and watching television.

The Science article was the subject of a piece that appeared on LiveScience.com, a website that reports on scientific and technological advances for laypeople. The research showed that when confronted with two tasks, the medial prefrontal cortex (the part of the brain that is colored green in the illustration) divides--half of the region focuses on one task, and half focuses on the other task. If a third task is added to the mix, the brain seems to "forget" one of the three tasks and returns to a binary sitation it is equipped to handle. The brain is simply not designed to perform accurately more than two tasks at once.
