Oedipus Complex:

The Oedipus complex, originated by Sigmund Freud, describes a child’s unconscious sexual desire for the parent of the opposite sex, coupled with feelings of jealousy and rivalry towards the same-sex parent. Freud saw it as a key stage in psychosexual development, particularly during the phallic stage (ages 3-6). Seeing the same-sex parent as a competitor for the attention and affection of the opposite-sex parent leads to jealousy, anger, and aggression toward the rival parent. The Oedipus complex is resolved when the child identifies with the same-sex parent and begins to model their behavior, eventually repressing the incestuous desires. Today the theory is controversial, with some questioning its universality and applicability to all cultures. Freud coined the name from the Greek tragedy Oedipus Rex, where Oedipus unknowingly kills his father and marries his mother. Also see the God Complex
