- A pattern of physiological reactions to stressors that includes stages of alarm, resistance, and exhaustion.
- The GAS begins with an alarm reaction, which is often called the fight-or-flight response because it helps us combat or escape stressors. The reaction releases “stress hormones,” like cortisol
- If stressor persists, or if new ones occur in quick succession, the alarm stage is followed by the stage of resistance, during which less dramatic but more
continuous biochemical efforts to cope with stress can have harmful consequences. For example, prolonged release of stress hormones can create chronic high blood pressure, damage muscle tissue, and inhibit the body’s ability to heal
- stage of exhaustion appears when various organ systems begin to malfunction or break down. People experience physical symptoms like fatigue, weight loss, heart disease
CRITIQUE --> the model does not allow for individual differences in the experience of stress
