Final answer:
The three-stage model of stress comprising recognition, coping, and exhaustion if stress persists, is called the General Adaptation Syndrome (GAS), developed by Hans Selye.
Step-by-step explanation:
The model describing the three-stage response to stress, consisting of the stages of recognition, coping, and potential depletion of resources, is known as the General Adaptation Syndrome (GAS).
Hans Selye's General Adaptation Syndrome comprises three stages: alarm reaction, stage of resistance, and stage of exhaustion. During the alarm stage, the body triggers a fight-or-flight response to the stressor. If the stress continues, the body enters the resistance stage, where it tries to adapt to the stressor, maintaining a state of alert with a reduced intensity. Prolonged stress can lead to the exhaustion stage, where the body's resources become depleted, increasing the risk for health issues like depression and heart attack.
