Psycho is a classic Hitchcock movie. At the beginning of the film, a secretary called Marion Crane ends up at a motel after embezzling money from her employer. She meet the motel’s owner-manager, Norman Bates, who invites her to a light dinner. She accepts but then she hears an argument between Norman and his mother. They eat in the motel parlor, where he tells her about his mother who is mentally ill. However, when Marion prepares to take a shower, she does not know that Norman is spying on her from a peephole. As she is showering, a female figure stabs her to death with a knife and then Norman appears.
He cleans up the crime scene, putting Marion’s body and her possessions into her car in the swamps. A week later, Marion’s sister Lila and her boyfriend Sam come to the motel and find Marion. When Lila finally sneaks up to Norman and his mother’s house, she finds a seated female figure who she discovers is the skeletal remains of Norman’s mother. At the end of the film, Norman is permanently trapped in the persona of his mother. In this story, the most obvious psychological theory which has been showed is the Oedipus complex. In this film, when Norman was 5 years old (in the phallic stage), his father was dead. He was brought up by his mother. In his life, the father is absent for a long time and the influence from his mother is ubiquitous. Norman cannot have the successful identification of the same-sex parent. He cannot truly bridge the stage of Oedipus complex. Norman has ambivalent feelings with his mother. He loves his mother, and meanwhile, he hates her.
He wants to find a substitute of his mother, but he also wants to find a female who is totally different from his mother. This love-hate feelings transform from unconscious to conscious via Norman’s talking about his mother with Marion. The irrational feeling between Norman and his mother becomes more and more drastic. Norman feels like falling into a trap. When Norman’s mother’s lover appears in his life, he becomes the son who kills the “father”. In his mind, he has grown up in the house, in which he has a very happy life with his mother. But one day when a man intrudes into their life, he killed the man to protect the relationship between him and his mother. Also, that he killed his mother is because of her faithlessness. On account of the love for his mother, and the compunction and self-accusation for his mother’s death, Norman performs the role of son and mother at the same time. It seems as if his mother is still alive (Lee, H., 2009, p. 34).
