Predicting attention-related errors before they happen

I just read a really interesting article about new research that could affect future ADHD treatment.  According to the article, scientists can now see distinct changes in brain wave activity just BEFORE an attention-related mistake is about to occur.

The study, conducted by the University of California, Davis, and the Donders Institute in the Netherlands, was published last week. The study participants sat at a computer for an hour with random numbers flashing onto the screen every two seconds.  The subjects were instructed to tap a button when any number except five appeared.  40% of the time, they hit the button when they weren't supposed to, which was to be expected because of the repetitive nature of the test.  Using MEG (magnetoencephalography) technology, the researchers witnessed changes in brain wave activity about a second before each of the errors occurred.

Researcher Ali Mazaheri suggested that this discovery could lead to new treatments for ADHD.  "Instead of watching behavior — which is an imprecise measure of attention — we can monitor these alpha waves, which tell us that attention is waning. And that can help us design therapies as well as evaluate the efficacy of various treatments, whether it's training or drugs."
