This paper begins by defining biofeedback and describing some of the major biofeedback machines. An historical perspective is provided of research literature on the relationship of biofeedback and learning. Biofeedback and relaxation are discussed and research is cited for the use of biofeedback techniques in relaxation training with children. Two research projects are presented in greater detail, a study that investigated the use of wrist temperature as a measure of principal brain wave frequency in 30 children, and a study that examined the effects of biofeedback on achievement of normal children by using a combination of alpha, wrist temperature, and autogenic training with 62 middle school children. Other research is reviewed which explored biofeedback training and: (1) achievement in normal children and children with learning disabilities; (2) hyperactive children; and (3) other behavioral changes in self-concept. The benefits of using biofeedback in counseling are discussed and the future of biofeedback techniques in education is considered. (NRB)
