Independent biofeedback self-regulation of EEG alpha and skin resistance.
Skin resistance and EEG alpha were recorded concurrently during alpha biofeedback, in which the participant attempted to control alpha, and during skin resistance biofeedback, in which the participant attempted to control skin resistance. Alpha production changed significantly (p less than .001) during alpha biofeedback, indicating successful self-regulation of alpha, but did not change significantly during skin resistance biofeedback. Similarly, skin resistance changed significantly (p less than .001) during skin resistance biofeedback but did not change significantly during alpha biofeedback. The results show independent control of alpha and skin resistance, and may reflect independent self-regulation of cognitive and somatic tension-relaxation systems.
