Freud's classification of ego defense mechanisms is very interesting, because he has classified 3 different kinds of anxiety known as realty, neurotic and moral anxiety. Freud found that these 3 forms of anxiety are often dealt with through many ego defenses that I have seen in many every day situations. Freud believed that defense mechanisms occur on an unconscious level and also that they deny or distort realty to make a situation less intimidating. Repression, denial, projection, reaction formation, regression, rationalization, identification, displacement and sublimation are the 9 ego defenses that Freud established. From studying these ego defense mechanisms I have realized that it is important to understand these defense mechanisms because they are associated with an individual's emotional and psychological growth.
