Abstract
Success or failure of EEG feedback training for alpha self-control can depend on how alpha activity is quantified and fed back. Alpha self-control failures usually employ the envelope technique. A new method, namely anintegrated alpha feedback technique, has been developed in this study. The occipital EEG was filtered to extract alpha activity (8-13Hz), and a full wave rectified and integrated for every 5 s using an electric integrator. The integrated alpha value was used as a quantification of alpha wave activity. The threshold of the binary feedback signal depended upon the integrated alpha value of each subject. Forty-eight subjects went through both the alpha enhancement and suppression trials. The results showed a significant difference in the integrated alpha value between the enhancement task and suppression task and a tendency of the interaction effects of tasks and trials. These results have been discussed in relation to the mediator of alpha self-control and clinical application of feedback techique.
