Where are our phobias "stored" and why are they different for everyone? Let's start with the first part of the question. The psychological phenomena associated with phobias and fears run in the limbic system of the brain, which is responsible for our emotions. It is here that the attachment of fear to a certain phenomenon is formed. One element of the limbic system (the amygdala gland) secretes stress hormones in response to the aggressive-protective state that the source of the fear causes. Why does a person develop phobias? It is the result of the interaction of unpleasant biological, psychological and social factors. We can describe these factors as follows👇🏻 Biology "dictates" us fear of heights, psychology fear of serious relationships, and sociology fear of public speaking. However, they all work together in one way or another.
