Highlights
Freud believed that psychological development unfolds in fixed psychosexual stages, driven by the balance between tension and pleasure. Tension arises from libido (sexual energy) build-up, and pleasure from its discharge. Each stage focuses on a different body part as a source of libido, and unresolved conflicts in any stage can lead to 'fixations' that manifest as adult personality traits.
Freud identified five main psychosexual stages: Oral (0-1 year), Anal (1-3 years), Phallic (3-6 years), Latency (6-12 years), and Genital (12+ years). The source of libido shifts from the mouth to the anus, to the genitals, then becomes dormant during latency, and returns to the genitals in the final stage. Freud emphasized the critical importance of the first five years for mental development.
In the oral stage, the baby's libido is centered around the mouth, deriving pleasure from activities like sucking, biting, and breastfeeding. Successful completion involves weaning. Over-indulgence can lead to oral personality traits such as smoking or nail-biting, particularly under stress.
During the anal stage, pleasure is derived from defecation. This stage introduces discipline through toilet training, fostering a child's understanding of authority. Harsh toilet training can result in an 'anal-retentive' personality (obsessive tidiness, punctuality, stubbornness), while overly liberal training can lead to an 'anal-expulsive' personality (disorganization, rebelliousness, generosity).
The phallic stage is characterized by interest in genitals. Freud posited that children develop unconscious desires for the opposite-sex parent and rivalry with the same-sex parent (Oedipus complex for boys, Electra complex for girls). Successful resolution involves identifying with the same-sex parent. Fixation can lead to a vain personality, recklessness, sexual dysfunction, and was controversially linked to homosexuality by Freud.
In the latency stage, the libido is dormant as the child directs energy towards schoolwork, friendships, and skill acquisition. This period is marked by the development of defense mechanisms and a tendency for children to play with others of the same gender.
Starting with puberty, the genital stage involves sexual experimentation. Successful navigation leads to loving, one-to-one relationships, particularly in adulthood. Fixations in this stage can result in intimacy and mental development issues throughout life.
Freud's theory has been criticized for illustrating a long, unknown time period between cause and effect, making it ambiguous. A major drawback is the lack of empirical evidence to support his claims, which were primarily based on his observations.
