Oedipus complex
Freud thought that, during the phallic stage, the young boy develops an intense sexual love for his mother. Because of this, he sees his father as a rival, and wants to get rid of him. The father, however, is far bigger and more powerful than the young boy, and so the child develops a fear that, seeing him as a rival, his father will castrate him. Because it is impossible to live with the continual castration-threat anxiety provided by this conflict, the young boy develops a mechanism for coping with it, using a defence mechanism known as 'identification with the aggressor'. He stresses all the ways that he is similar to his father, adopting his father's attitudes, mannerisms and actions, feeling that if his father sees him as similar, he will not feel hostile towards him.
