Probably not. CNN recently posted an interesting video of Dr. Sanjay Gupta explaining what happens to the brain while multitasking. Gupta argues that we’re not actually doing two tasks at once; we’re diverting our attention from one task to work on another, and giving each just partial attention.
He references a study done on multitasking while driving. It showed that listening to sentences while driving decreased the driver’s attention to operating the car by 37%. So rather than listening and driving simultaneously, you’re offering each activity your reduced attention, resulting in substandard performance.
Now think of how often this happens at work.»
