While biofeedback is being used extensively in the clinic and the laboratory, a great deal of variability exists among biofeedback users with respect to instrumentation, treatment protocols, techniques of data acquisition, and methods of data analysis. It is argued that the use of computers in biofeedback will help reduce some of this variability. Other advantages of computers in biofeedback are discussed. Several presently available automated systems are reviewed. Implications for future biofeedback research are also discussed. © 1981 Psychonomic Society, Inc.
