Which psychosexual stage according to Freud occurs during infancy?

The correct choice is the Oral Stage, which is the first of Freud's psychosexual stages of development. This stage occurs during infancy, specifically from birth to about 18 months. During this period, an infant’s pleasure centers on the mouth. Activities such as sucking, biting, and chewing are the primary sources of interaction for the child, allowing for exploration of their environment.

Freud believed that experiences during the oral stage influence personality development, as infants derive comfort and satisfaction from oral stimulation. For example, successful navigation of this stage leads to the development of trust and comfort, while difficulties may lead to issues such as dependency or aggression later in life.

In contrast, the Anal Stage follows the Oral Stage, typically occurring from about 18 months to three years, where the focus shifts to controlling bladder and bowel movements. The Phallic Stage, occurring around ages three to six, emphasizes the genital area and involves the Oedipus and Electra complexes. The Latency Stage takes place from about six years to puberty and is characterized by a focus on social development rather than sexual interests. Understanding these stages is crucial for grasping Freud's broader theories about human development and personality formation.
