What were the main findings from hans selye’s general adaptation syndrome?

Phases of stress, including arousal, coping, and exhaustion, was first discovered in rats.

Explanation:

General adaptation syndrome. Directly related to stress, the general adaptation syndrome is a set of physical and psychic symptoms that appear when the subject must face a novel situation.

It is also known as stress syndrome or general stress adaptation syndrome.

Selye's general adaptation syndrome is named after the name of its discoverer, Hans Selye, whose finding was a great advance for Psychology.

The stress syndrome depends on several factors and their interrelation between them, first of all it takes an internal or external stressor agent high enough to require me a response, secondly the stimulus must be perceived as a threat from the subjective point of view, which does not have to coincide with an objective threat, I can perceive a grasshopper as a threat, and for no one else it is, but for the subject in question it is non-negotiable that a grasshopper is a threat. And thirdly, there is a lack of means to deal with the possible threat with ease and comfort.

Depending on these three factors, a particular stressor agent may cause responses of pleasure, discomfort, anxiety, fear or panic. If the stimulus is effectively aggressive and is maintained over time, the body will go through the phases of alarm, resistance and exhaustion. Producing in each case the negative effects that excess stress has on the organism when it is maintained over time beyond the level of adaptation itself.

The body responds to an imminent danger in three phases: alarm, adaptation and exhaustion.
