CHRONIC FREE OPERANT AVOIDANCE AS A PSYCHOLOGICAL STRESS: A RE-EVALUATION,
Abstract
Rhesus monkeys were maintained for 30 days on a modified free operant avoidance schedule in order to evaluate this paradigm as a chronic stress. Subjects were run in four groups to assess the separate contributions of human contact, intersubject interaction and chair restraint. Urinary 17-hydroxycorticosteroid levels and gastrointestinal ulcers were used as stress measures. Chronic exposure to this paradigm did not necessarily produce a stressed organism or gastrointestinal pathology. The adrenal corticosteroids did, however, provide a sensitive, objective index of emotionality. (Author)
