The role of feedback was reviewed by examining our previous experiments on biofeedback-aided voluntary heart rate (HR) control. The task of first experiment was ordinary HR increase or HR decrease during 12-days. The results of this experiment showed that the subject's awareness of the measured variables, required task, meaning of feedback, and the relationships among these was crucial in determining his or her performance. The task using the rest four experiments was a kind of tracking task where subject was required to keep one's HR or HR-like motor response in the target area as much as possible. The independent variable in those experiments was feedback delay, or time lag, between response and the presentation of feedback signal. The series of results obtained suggest that in the tasks such as HR-tracking, a mechanism similar to that of motor-learning is at work, and that even a slight delay in feedback can disturb the performance. These observations suggest when the feedback signal was fit for the required task, the performance complies with the theories of closed-loop feedback control in which case the effects of biofeedback are maximized.
