| This article was written as an introduction to a special issue of Behavior Modification dedicated to studies in the field of respiratory psychophysiology. Although the invited articles that constitute this special issue cover a fairly broad range of topics, priority was given to articles that focus on the role of respiration in panic disorder. Attention is directed to the fundamental role of breathing in applied psychophysiology and to the encouragement of research in the modification of breathing behavior. The connection between respiratory psychophysiology and behavior modification is explained by reference to (a) a recent article on Pavlovian and operant control of breathing behavior and (b) four published volumes of selected articles dedicated exclusively to the field of respiratory psychophysiology. The present special issue of Behavior Modification marks the fifth volume. |
