Alec Rubenstein PSYC 101; Section 2 Describe Hans Selye’s General Adaptation Syndrome: what body system is responding to the stressor? What are the three different stages and how are they characterized? Hans Selve’s General Adaptation Syndrome is a model of the body’ stress response, consisting of three stages: alarm, resistance and exhaustion. Selye developed his theory while exposing a multitude of animals to a variety of stressors. Selye found that the physiological arousal seen in the animals were largely the same and independent of the type of stress. He concluded that stress reactions are nonspecific. From this research, Selye developed the three part model explaining the body’s stress response. The first stage is the alarm reaction which occurs when the animal first becomes aware of a stress. Physiological arousal begins as the body prepares to combat the threat. This is in effect the fight-or-flight reactions. As the stress continues, the animal enters a period of prolonged stress.
