Multi-Tasking Muddling Teen Brains?

I listened to NPR on my way to work this morning and heard this story.

Studies with adults have shown that when we multi-task we are actually less productive because the brain has to disconnect and then recreate thought processes as we bounce from task to task.

After reading the article, I wondered if the same is true for the kids of Generation M - a group who learned multi-tasking behavior from the cradle. Do their brains experience these same "brown-outs" or have they adapted/evolved/adjusted?

So my question for all of you is - do you think your students multi-task more productively than you do - or are we all just muddling our brains?
