“…One of the more important yet largely unresearched predictions of the original physiologically based model of stress was that an individual's capacity to cope with a stressor would be influenced, among several factors, by the demands placed upon that person by other sources of environmental stress (Selye, 1956). To put it in alternative terms, if the effects of various social and physical stressors in the environment share some common mechanism of impact, one cost of coping with environmental demands is reduced capacity to respond to ensuing adaptive challenges (Catalano, 1984;Dubos, 1965;Fleming, Baum, & Singer, 1984).…”
