To that we owe our existence. So we have reason to be glad that the physicists were wrong in their fondest beliefs. In actuality, of course, it does not matter what physicists thought. The universe exists quite independently of what they think. And EEG biofeedback works quite independently of what Barkley thinks.
Facts are relentless.
Ultimately, they will win the field. Among the precious little facts which don't fit the conventional picture is the one that EEG training changes laterality, or handedness. The data are widely scattered before training, showing mixed dominance in some instances. These data were not expected, and no one is making this a litmus test of remediation of attention deficits or learning disabilities. We postulate that many attention deficits, which are heritable, are compounded by birth trauma, which was prominent in our study population.
