Biofeedback as a placebo: Anxiety reduction facilitated by training in either suppression or enhancement of alpha brainwaves
Assessed the differential effects (on experiential reports of anxiety) of actual performance and perceived success at an EEG biofeedback task. 10 college students who were high in trait anxiety (MMPI, State-Trait Anxiety Inventory) underwent training in either the suppression of enhancement of EEG alpha activity with the expectation that success at their biofeedback task would result in reductions of chronic anxiety levels. Both groups experienced significant reductions in both trait and state anxiety. Anxiety reductions were highly correlated with the trainees' ratings of perceived success at the feedback task but were unrelated to either the direction or magnitude of the changes in their alpha activity.

Metrics Abstract Subjects who were either high or low in trait anxiety used alpha feedback to increase and to decrease their electroencephalographic alpha activity. The alpha changes were tightly linked to anxiety changes, but only in high anxiety subjects (for whom anxiety was reduced in proportion to alpha increases, and was increased in proportion to alpha suppression). Low trait-anxiety subjects were superior at both enhancement and suppression training, but their alpha changes were not related to anxiety changes. In both groups, anxiety changes were generally unrelated to either resting levels or changes in frontalis electromyograms and respiration rate. These results suggest that long-term alpha feedback training (at least 5 hours) may be useful in anxiety therapy
