“…Both a generalized homeostatic theory of psychophysiological disorders (Christie, 1975;Stoyva, 1976Stoyva, , 1977 and a more complex conceptualization of psychophysiological disorders, such as the three-stage theory proposed by Sternbach (1966), include in their definition of psychophysiologic abnormality an impaired recovery process. This "slowness of recovery" has been documented, albeit inconsistently, in many disorders such as hypertension (Brod, Fencl, Hejl, & Jirka, 1959;White & Gilda, 1937), anxiety (Malmo, Shagass, & Davis, 1950), migraine headache (Arena, Blanchard, Andrasik, Applebaum, & Myers, in press;Anderson, Stoyva, & Vaughn, 1982), and Raynaud's disease (Charles & Cormick, 1970).…”
