The literature review presents an explanation of biofeedback and a critical evaluation of the research pertaining to electroencephalographic (EEG) biofeedback training for the hyperactive and/or learning disabled child. Three hypotheses are examined: whether EEG biofeedback training is efficacious; whether EEG biofeedback training is more effective than electromyographic (EMG) biofeedback training; and whether biofeedback therapy with a child affects the family system. The review supports the use of EEG biofeedback as effective, finds the greater effectiveness of EEG biofeedback over EMG biofeedback unclear, and concludes that biofeedback training has a potential for impact on the family. Briefly considered are implications for counselors in marriage and family therapy. (DB)
