Hey, kids, don't study while watching TV.

Duh!

WASHINGTON - Your parents were right, don't study with the TV on. Multitasking may be a necessity in today's fast-paced world, but new research shows distractions affect the way people learn, making the knowledge they gain harder to use later on.

But wait, Sherlock! There's more (if you're capable of learning, that is):

As Poldrack explains it, the brain learns in two different ways. One, called declarative learning, involves the medial temporal lobe and deals with learning active facts that can be recalled and used with great flexibility. The second, involving the striatum, is called habit learning....

...The problem, Poldrack said, is that the two types of learning seem to be competing with each other, and when someone is distracted, habit learning seems to take over from declarative learning.

"We have to multitask in today's world, but you have to be aware of this," he said. "When a kid is trying to learn new concepts, new information, distraction is going to be bad, it's going to impair their ability to learn."

This means that don't try to multitask when learning -- for example, don't try to watch Fox and get the news of what's happening at the same time. They work at cross purposes and leave you confused.
