A University of Arizona doctoral student finds that an EEG brain scan can predict, with 80% accuracy, when SAT math students will make a mistake within 20 seconds of beginning the problem.
The student is looking at brain wave data, but the article does not go into details about which brain waves he is looking at or what kind of patterns predict the mistake. I'm guessing that the beta wave is involved, but is the indicator the beta wave levels being different between the right and left sides of the brain? Or is it a strengthening of one of the other brain wave types?
