This book investigates the scientific validity and empirical foundations of biofeedback as a clinical intervention. Edward B. Blanchard, a recognized authority in behavioral medicine, moves away from popular or anecdotal accounts to provide a rigorous examination of the field. By synthesizing existing research, he establishes a framework for understanding how physiological monitoring can be applied within professional psychological practice.

Experts highlight this as a foundational text for those seeking a scientific rather than popular understanding of biofeedback. Readers frequently note the academic density of the prose, which prioritizes clinical evidence over general accessibility.
