“Is Our Reaction To Stressful Events Innate or Learnt?”

        

To be blunt the answer is both, but to different degree’s. Everybody has a pre-ordained response to stress on a purely physical level. When we are put into a stressful situation are body goes through a whole host of changes that aid in dealing with stress, or rather physical stress. The so called flight or fight response is useful when you suddenly need a lot of energy but if you are at work and this response activates you have no need of sudden energy. This then becomes a problem when the stress becomes chronic.

The pioneer of stress research was Selye. In 1936 he conducted experiments on rat’s attempting to discover a new sex hormone. During the procedures he noticed a physiological reaction but he knew that no known hormone produced such effects. Therefore he assumed he had discovered a new hormone but when he injected another substance the same reaction was observed. Selye did not give up there though, he changed his direction. “It suddenly stuck me that one could look (at the experiments) from an entirely different angle. (Perhaps) there was such a thing as a non-specific reaction of the body to damage of any kind” (Selye, 1976, Psychology: A New Introduction, pg 68). Selye later confirmed that when rats are exposed to adverse conditions such an electric shocks, cold and surgical procedures the same reactions took place. Selye also noticed that the response to the various stressors was identical and not specific to the type of stressor. Selye labelled this the General Adaptation Syndrome (G.A.S).

G.A.S has three stages which are Alarm, Resistance and Exhaustion. The first stage or the Alarm stage is triggered by the senses and the confirmation that the stimulus is a stressor. Once the body has confirmed that a stressor is present then the first of two smaller phases occur. The shock phase shows a drop in blood pressure and muscle tension and then is quickly followed by the second of the two phases which is the counter-shock phase which recognises that the body may be harmed. The body then releases corticosteroids which have two effects. The first of these is to increase muscle development and the second is to stimulate the liver to release stored sugar which is used to mobilise energy quickly. These effects dwindle rapidly if the stressor proves to be none harmful if not then the body proceeds to the second stage of G.A.S, the Resistance stage. In this stage the aforementioned responses drop slightly they maintain a higher than normal level. The corticosteroids begin to affect the normal running of other systems such as the immune system and the turnover of cells, particularly in the stomach. This process is known as immunosuppresion. The body is running faster than it should be and so is using up its resources faster than it is replacing them. If the stressor is removed then the body returns to normal with little or no damage, however if it is not removed then the body moves on to the third and final stage the exhaustion stage. In this stage the bodies natural shut of system is overridden and the body continues the above processes. This eventually leads to tissue and muscle damage, blood sugar levels drop and the endocrine systems are damaged.

Looking at this very earlier research we can see that even basic mammals such as rats have a response to stressful events. We can also see, from his later research into his theory G.A.S, that the response to stress is the same whether it is an external or internal threat suggesting that the response is not learnt as if it was learnt it would be specific to the threat. For example, according to Selye, when at work and your boss suddenly gives you a huge responsibility you were not prepared for your body would react in the same way ...
