Adaptation Syndrome :: essays research papers

What Is General Adaptation Syndrome (GAS)General Adaptation Syndrome is a theory formulated in 1936 by Dr. Hans Seyle, a storied figure in the field of stress research. Gas depicts the process of prolonged exposure to stress by separating behaviors into 3 stages. The Alarm Reaction, Resistance and Exhaustion Stage. This behavioural model is such a valuable tool in the study of stress research because it explains both the physiological and psychological effects of stress on the human body.The Alarm Reaction StageAll Stress is caused by external stimuli the immediate response to these ch eitherenges or threats is the Alarm Reaction stage. In the A.R.S. this cognition of a threatening situation caused by the brain sends biochemical messages to various parts of the body, resulting in bodily changes such as increased or strong heart beats, shallow fast-breathing or muscle tension (refer to appendix xxx). It is this physical reactions that characterize this early stage is the GAS model . (Author, pg).Dr. Selye preformed most of the early work on the adaptation syndrome. His experiments in general looked at harmful stimuli on the response of the body. In an experiment, Seyle exposed a large number of rats to a refrigerated mode where the temperature was near freezing,(Author pg) during the first 48 hours they developed the typical manifestations of the alarm reaction. This was proved by killing ten animals at the end of the second day all of them had large fat-free adrenals, small thymuses, and stomach ulcers. (Seyle, 1956 88). This experiment conducted illustrated the vast number of physical changes the body undergoes in stressful situations.
