define hans selye psychology
Hans Selye (1907- 1982) was a Hungarian endocrinologist, first to give a scientific explanation for biological stress. Hans Selye explained his stress model based on physiology and psychobiology as General Adaptation Syndrome (GAS).His model states that an event that threatens an organismâs well-being (a stressor) leads to a three-stage bodily response: Stage 1: Alarm.onclusion. Hans Selye's theory profoundly influenced the scientific study of stress. Stress is a state produced by a change in the environment and the nature of the stressor is variable.
