Biofeedback and Behavior: A NATO Symposium, held on 27-30 July 1976 at the Max Planck Institut fUr Psychiatrie in MUnchen, was a mul tidisciplinary meeting that explored both theoretical and applied issues arising from the use of biofeedback procedures for the control of visceral, central nervous system and skeletal events. The symposium was multi national in its composition. Financial support for the symposium was initially provided by the Scientific Affairs Division of the North Atlantic Treaty Organization as part of their continuing series of scientific symposia. Funds made avail able by a grant from the United States Office of Naval Research permit ted wide-spread international participation in the symposium. The facil ities for the meeting were graciously provided by the Max Planck Institut ilir Psychiatrie. We thank each of these organizations for their support in making this symposium possible. A special thanks is due to Dr. B.A. Bayraktar of the Scientific Affairs Division of NA TO and Dr. Donald Wood ward of the U. S. Office of Naval Research, whose counsel contributed substantially to the organization of this meeting. The planning of this symposium was carried out in consultation with members of the organizing committee: Rolf Engel, Pola Engel-Sittenfeld, Laverne C. Johnson, George H. Lawrence, Gary E. Schwartz, and Da vid Shapiro. The final form of this symposium reflects their contribu tions, for which we are grateful.
