Multitasking has limits

A new study finds that multitasking has its limits, and that humans may not be able to perform more than two complicated jobs at one time.

The brain has two lobes that divide the responsibility equally when two tasks are being carried out at the same time.

Trying to complete three tasks at once overwhelms the human frontal lobe's capacity, but scientists say that doing two tasks at once is fine.

The work could have practical implications in health and also applications to areas like traffic safety, including air traffic control or driving while using a cell phone.
