In the oral stage (birth to 1 year), pleasure is focused on the mouth. Eating and the pleasure derived from sucking (nipples, pacifiers, and thumbs) play a large part in a baby’s first year of life. At around 1 year of age, babies are weaned from the bottle or breast, and this process can create conflict if not handled properly by caregivers. According to Freud, an adult who smokes, drinks, overeats, or bites her nails is fixated in the oral stage of her psychosexual development; she may have been weaned too early or too late, resulting in these fixation tendencies, all of which seek to ease anxiety.

After passing through the oral stage, children enter what Freud termed the anal stage (1–3 years). In this stage, children experience pleasure in their bowel and bladder movements, so it makes sense that the conflict in this stage is over toilet training. During this stage of development, children work to master control of themselves. Freud suggested that success at the anal stage depended on how parents handled toilet training. Parents who offer praise and rewards encourage positive results and can help children feel competent. Parents who are harsh in toilet training can cause a child to become so fearful of soiling that they over-control and become fixated at the anal stage, leading to the development of an anal-retentive personality. The anal-retentive personality is stingy and stubborn, has a compulsive need for order and neatness, and might be considered a perfectionist. If parents are too lenient in toilet training, the child may fail to develop sufficient self-control, become fixated at this stage, and develop an anal-expulsive personality. The anal-expulsive personality is messy, careless, disorganized, and prone to emotional outbursts.

Freud’s third stage of psychosexual development is the phallic stage (3–6 years), corresponding to the age when children become aware of their bodies and recognize the differences between boys and girls. The erogenous zone in this stage is the genitals. Conflict arises when the child feels a desire for the opposite-sex parent, and jealousy and hatred toward the same-sex parent. For boys, this is called the Oedipus complex, involving a boy's desire for his mother and his urge to replace his father who is seen as a rival for the mother’s attention. The Oedipus complex is named for the Greek myth of Oedipus, who unwittingly kills his biological father and marries his biological mother. According to Freud, the boy is afraid his father will punish him for his feelings, so he experiences castration anxiety. The Oedipus complex is successfully resolved when the boy begins to identify with his father as an indirect way to have the mother. Failure to resolve the Oedipus complex may result in fixation and development of a personality that might be described as vain and overly ambitious.

Freud described penis envy, which he alleged girls experience because they do not have a penis. Girls also experience the Electra complex. The Electra complex, while often attributed to Freud, was actually proposed by Freud’s protégé, Carl Jung (Jung & Kerenyi, 1963). A girl desires the attention of her father and wishes to take her mother’s place. While Freud initially embraced the Electra complex as a parallel to the Oedipus complex, he later rejected it, yet it remains as a cornerstone of Freudian theory, thanks in part to academics in the field (Freud, 1931/1968; Scott, 2005).

Following the phallic stage of psychosexual development is a period known as the latency period (6 years to puberty). This period is not considered a stage, because sexual feelings are dormant as children focus on other pursuits, such as school, friendships, hobbies, and sports. Children generally engage in activities with peers of the same sex, which serves to consolidate a child’s gender-role identity.

The final stage is the genital stage (from puberty on). In this stage, there is a sexual reawakening as the incestuous urges resurface. The young person redirects these urges to other, more socially acceptable partners (who often resemble the other-sex parent). People in this stage have mature sexual interests, which for Freud meant a strong desire for the opposite sex. Individuals who successfully completed the previous stages, reaching the genital stage with no fixations, are said to be well-balanced, healthy adults.

While most of Freud’s ideas have not found support in modern research, and several contemporary researchers rejected his premises, we cannot discount the contributions that Freud has made to the field of psychology. It was Freud who pointed out that a large part of our mental life is influenced by the experiences of early childhood and takes place outside of our conscious awareness; his theories paved the way for others.

While Freud's focus on biological drives led him to emphasize the impact of sociocultural factors on personality development, his followers quickly realized that biology alone could not account for the diversity they encountered as the practice of psychoanalysis spread during the time of the Nazi Holocaust. The antisemitism which was prevalent during this period of time may have led mainstream psychoanalysts to focus primarily on the universality of the psychological structures of the mind.
