This volume investigates the physiological and psychological mechanisms through which individuals can exert voluntary control over autonomic bodily processes using biofeedback technology. Joe Kamiya, a pioneer in the field of consciousness research, compiles foundational studies to examine how external monitoring of internal states allows subjects to modulate brain waves, heart rate, and muscle tension. The text presents a framework for understanding the intersection of operant conditioning and biological regulation, arguing that consciousness can be systematically trained to influence involuntary systems.

Experts recognize this collection as a seminal text that helped define the early scientific parameters of biofeedback research. Readers frequently note the academic density of the prose, which reflects the rigorous experimental standards of 1970s psychological research.
