In his model of the child's psychosexual development, Sigmund Freud describes five stages. Freud believed that the child discharges his/her libido through a distinct body area that characterizes each stage. The stages are:
The latency stage may begin around the age of 7 and may continue until puberty, which can begin anywhere from the age of 9 to the age of 17. The age range is affected by childrearing practices; mothers in developed countries, during the time when Freud was forming his theories, were more likely to stay at home with young children, and adolescents began puberty on average later than adolescents today. Freud described the latency phase as one of relative stability. No new organization of sexuality develops, and he did not pay a lot of attention to it. For this reason, this phase is not always mentioned in descriptions of his theory as one of the phases, but as a separate period. The latency phase originates during the phallic stage when the child's Oedipus complex begins to dissolve. The child realizes that his/her wishes and longings for the parent of the opposite sex cannot be fulfilled and will turn away from these desires. They start to identify with the parent of the same sex. The libido is transferred from parents to friends of the same sex, clubs and hero/role-model figures. The sexual and aggressive drives are expressed in socially accepted forms through the defense mechanisms of repression and sublimation. During the latency phase, the energy the child previously put into the Oedipal problem can be used for developing the self. The superego is already present, but becomes more organized and principled. The child acquires culturally regarded skills and values. The child has evolved from a baby with primitive drives to a reasonable human being with complex feelings like shame, guilt and disgust. During this stage, the child learns to adapt to reality and also begins the process of what Freud terms 'infantile amnesia': the repression of the child's earliest traumatic, overly sexual or evil memories.

Freud's daughter, the psychoanalyst Anna Freud, saw possible consequences for the child when the solution of the Oedipal problem is delayed. She states that this will lead to a variety of problems in the latency period: the child will have problems with adjusting to belonging to a group, and will show lack of interest, school phobias and extreme homesickness. However, if the Oedipal problem is resolved, the latency phase may bring the child new problems, like joining gangs, rebelling against authority and the beginnings of delinquency. On the contrary, Jacques Lacan emphasized the importance of Oedipal problem for individuals' development and states that unsuccessful resolution of it is the most likely cause for inability to come to terms with symbolic relations such as the law and expectations of society. In most extreme cases of failure—where there is no opposition for the child's access to his mother and vice versa—the result is perversion. The developmental psychologist and psychoanalyst Erik Erikson developed a stage model for the evolution of the ego. The latency phase corresponds to his stage of competence, or 'industry and inferiority', age 5 to puberty. The child is eager to learn new skills. During this stage, the child compares his/her self-worth to others. Because the child can recognize major disparities in his/her abilities relative to other children, the child may develop a sense of inferiority to them.
