The literature relating to the learned control of autonomic processes, especially cardiovascular processes demonstrating that the activities of visceral response systems may be modifi ed by operant reinforcement and biofeedback procedures, has grown exponentially. This research seems to show behavioral properties in the cardiovascular system that were previously believed to be exclusive attributes of the somatic response systems; the implications of this for possible therapeutic use have received widespread publicity. Questions remained unanswered-about the nature of "voluntary" control and the conditions necessary for establishing it, the reciprocal effects of conditioned changes in cardiovascular and psychological or behavioral functioning, the use of cardiovascular events to index behavioral states, and the principles and techniques whereby operant conditioning of the cardiovascular system can be clinically applied.

This book contains original essays by leading authorities on the subject. When originally published, it represented the first comprehensive overview of the entire field of cardiovascular psychophysiology. It begins with three chapters that provide an overview of the subject and the major contemporary measurement techniques. Part II contains six experimental studies of cardiovascular function dealing with the interactive nature of cardiovascular and behavioral events.

This book serves as a benchmark for all future research in cardiovascular psychophysiology, and as such it will be of continuing interest to advanced students, researchers, scholars, and teachers in the fields of psychophysiology, psychiatry, cardiology, and biomedical engineering.

It was my original intention to write a reasonably advanced psycho physiology text that would go beyond cardiovascular activity. This I believed would require a collaborative effort since my expertise outside of cardiovascular psychophysiology is too limited. After some initial limited efforts to organize such a venture, it became apparent that a text of this nature was not feasible. Thus, the effort was dropped. I did, however, receive encouragement to write the present monograph, which is more a personalized document than a text. As will become apparent, this monograph relies heavily on research from my laboratory and details the manner in which our conceptualizations of the issues have developed. At first, I believed such an effort premature since such a personalized document was something one composes upon retire ment. However, I was persuaded by some individuals (who shall re main anonymous, just in case they end up regretting their actions) to undertake the present effort. There are several people, who have rendered assistance in the preparation of this monograph, for whose efforts I am extremely grate ful. Extensive editorial assistance and encouragement were provided by Kathleen C. Light and Alberto Grignolo. Also assisting editorially were Ellen Z. Curtin, Allison Cahill, and Carolyn Williams. I wish also to thank my long-time secretary, Virginia Hodson, and Jenny Adams, for their typing assistance. There are six people to whom I would like to dedicate this book.
