Studied was the effectiveness of biofeedback techniques in reducing the hyperactive behavior of five hyperactive and four nonhyperactive children (all in elementary level learning disability classes). After 10 15-minute biofeedback training sessions over an 8-week period, Ss learned to raise their finger temperatures an average of 12.92 degrees (indicating muscle relaxation), and increased their attending behavior by 17.4%. Slight increases were also noted in self-concept and teachers' ratings of classroom performance. (Author/IM)
