During which psychosexual stage does Freud suggest personality begins to develop?

Freud's theory of psychosexual development posits that the foundation of personality is largely shaped during the oral stage, which occurs from birth to about 18 months of age. During this early stage, infants derive pleasure and satisfaction primarily through oral activities, such as sucking and biting. The experiences and interactions with caregivers during this stage play a crucial role in shaping a child's personality.

The way a caregiver responds to an infant's oral needs can influence later personality traits. For instance, if an infant's needs are adequately met, they may grow up to be more trustful and secure. Conversely, if these needs are not sufficiently met, it may lead to issues such as dependency or aggression in later life. Thus, the oral stage is vital in forming a child's early personality characteristics and coping mechanisms.

In contrast, other psychosexual stages focus on different areas of development and emerge later in a child's life. The anal stage, occurring between 18 months and three years, emphasizes control and autonomy, while the phallic stage, which follows, introduces the exploration of gender identity and relationships with parents. The latency stage, occurring from around age six to puberty, focuses on socialization and skill development but does not play a central role in the initial development of personality
