1. The oral period is the second year from birth to birth. The stimulation to the baby's oral cavity at this stage, such as sucking and swallowing, is the main source of sexual satisfaction.
2. The anal period is from 1 to 3 years old, and the sensitive area at this stage turns to anus.
3. The stage of sex organs is from 3 to 5 years old, and at this stage, genitals become sexually sensitive areas. Sexual satisfaction at this stage includes sexual fantasies about heterosexual parents and playing with and showing genitals. Oedipus complex and Oedipus complex are produced at this stage. The first three stages are important stages of personality development, which lay the foundation for adult personality model.

Self-defense mechanism theory:
Freud believed that self-defense mechanism is an irrational and distorted way to deal with anxiety, psychological conflict or frustration, which is the function of self. Freud's daughter Anna sorted out Freud's related expositions and found that he mainly put forward eight self-defense mechanisms: negation, displacement, projection, rationalization, reverse action, retrogression, repression and sublimation.
Denial refers to an individual's refusal to admit the existence of the facts that cause his pain and anxiety. Displacement means that when an individual's instinctive impulses and desires are not satisfied on one object, they will be transferred to other objects.
Projection refers to blaming others for one's inner desires, impulses and socially unacceptable behaviors.
Rationalization is to replace the original reason with a reason that you can accept.
Reverse action refers to replacing repressed desire with opposite behavior.
Backwardness means that when individuals encounter setbacks in the early stage of development, they respond to reality with childish behavior, with the aim of gaining sympathy from others and relieving anxiety.
Repression refers to putting thoughts and impulses that cause anxiety into the subconscious.
Sublimation refers to the transfer of instinctive impulse to social identity.
