Stages of Psychosexual Development
Freud believed that personality develops during early childhood: Childhood experiences shape our personalities as well as our behavior as adults. He asserted that we develop via a series of stages during childhood. Each of us must pass through these childhood stages, and if we do not have the proper nurturing and parenting during a stage, we will be stuck, or fixated, in that stage, even as adults.
psychosexual stages
In each psychosexual stage of development, the child’s pleasure-seeking urges, coming from the id, are focused on a different area of the body, called an erogenous zone. The stages are oral, anal, phallic, latency, and genital (Table 1).
| Stage | Age (years) | Erogenous Zone | Major Conflict | Adult Fixation Example |
|---|---|---|---|---|
| Oral | 0–1 | Mouth | Weaning off breast or bottle | Smoking, overeating |
| Anal | 1–3 | Anus | Toilet training | Neatness, messiness |
| Phallic | 3–6 | Genitals | Oedipus/Electra complex | Vanity, overambition |
| Latency | 6–12 | None | None | None |
| Genital | 12+ | Genitals | None | None |
Freud’s psychosexual development theory is quite controversial. To understand the origins of the theory, it is helpful to be familiar with the political, social, and cultural influences of Freud’s day in Vienna at the turn of the 20th century. During this era, a climate of sexual repression, combined with limited understanding and education surrounding human sexuality, heavily influenced Freud’s perspective. Given that sex was a taboo topic, Freud assumed that negative emotional states (neuroses) stemmed from suppression of unconscious sexual and aggressive urges. For Freud, his own recollections and interpretations of patients’ experiences and dreams were sufficient proof that psychosexual stages were universal events in early childhood.
Oral Stage
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.
Anal Stage
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.
Phallic Stage
In Freud’s model, the phallic stage (about ages 3–6) is when children become more aware of their bodies and begin noticing sex differences. Freud argued that, during this period, the child’s attention and curiosity are more focused on the genitals than in earlier stages.
Freud proposed that the central conflict of this stage involves strong feelings directed toward parents:
- the child develops an unconscious desire for the other-sex parent (wanting closeness, attention, or “special” status), and
- feels rivalry, jealousy, or resentment toward the same-sex parent, who is experienced as a competitor for that parent’s attention.
The Oedipus complex (boys)
Freud called this conflict in boys the Oedipus complex. In his description the boy unconsciously desires the mother and sees the father as a rival, and also fears punishment from the father for these feelings—what Freud labeled castration anxiety.
Freud believed this conflict is “resolved” when the boy reduces rivalry and instead identifies with the father—adopting the father’s attitudes and behaviors. Freud argued that identification helps the child internalize social rules and values, contributing to the development of the superego (conscience). If the conflict is not resolved, Freud claimed it could lead to fixation and later personality patterns such as excessive vanity or overambition.
The Electra complex and “penis envy” (girls)
A parallel idea for girls is often called the Electra complex, a term more closely associated with Carl Jung than Freud (Jung & Kerényi, 1963). In this framework, the girl desires the father’s attention and views the mother as a rival.
Freud also proposed penis envy—the idea that girls feel anger or a sense of loss because they do not have a penis, and that this shapes their feelings toward the mother. Freud’s views here are among the most criticized parts of his theory today due to sexism and a lack of strong empirical support. While Freud’s position shifted over time and he did not consistently endorse the Electra label, these concepts have remained widely discussed in Freudian and psychoanalytic traditions (Freud, 1931/1968; Scott, 2005).
Latency Period
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.
Genital Stage
The genital stage (puberty onward) marks the final phase of psychosexual development. According to Freud, sexual feelings reawaken during this period, and individuals redirect their desires toward socially acceptable partners outside the family—often partners who resemble the other-sex parent. Freud believed that individuals who successfully navigated all previous stages without fixations would develop into psychologically healthy adults with mature sexual interests.
What Freud Got Right (and What Didn’t Hold Up)
Many specific claims in Freud’s psychosexual stage theory are not strongly supported by modern research. Even so, Freud’s influence on psychology is significant. He helped popularize the idea that:
- early childhood experiences can shape later development
- much mental activity happens outside conscious awareness (the unconscious)
- inner conflicts can influence emotions and behavior in everyday life
His work also helped inspire later theories of personality and forms of talk therapy (even when those later approaches disagreed with Freud’s explanations).
Psychodynamic Theories Today
Contemporary Perspectives
Modern psychodynamic approaches have moved beyond many of Freud’s specific claims—particularly the idea that children experience sexual desires in the way his stage model suggests. Research on classic Freudian concepts is mixed: some ideas have not held up, while others have been updated and supported in newer forms.
For example, broad personality themes related to dependence, control, and competition can usefully describe how people relate to others and cope with stress—even without explaining those patterns through Freud’s stage model.
Below are three psychodynamic concepts that have strong support in contemporary research.
psychodynamic takeaways
Unconscious Processes Influence Behavior
- We perceive and process far more information than we realize, and much of our behavior is shaped by feelings and motives outside our conscious awareness (Bornstein, 2009, 2010). Evidence for unconscious influences has become so compelling that it is now a central element of cognitive and social psychology (Robinson & Gordon, 2011). Contemporary neuroscience research continues to demonstrate that unconscious processing affects decision-making, emotional responses, and social behavior—though researchers debate the precise scope and limits of these influences (Mudrik & Deouell, 2022).
Defense Mechanisms Affect Psychological and Physical Health
- People differ in the defenses they rely on, and researchers now study each person’s “defense style”—their characteristic pattern of defenses. Contemporary research confirms that certain defenses are more adaptive than others: mature defenses like humor and sublimation are associated with better psychological functioning, while immature defenses like denial and projection are linked to greater psychological distress (Di Giuseppe et al., 2020; Vaillant, 2020). A recent cross-cultural study across six countries found that higher use of mature defenses predicted fewer mental health symptoms during stressful periods, while immature defenses predicted more symptoms (Prout et al., 2024). Denial in particular can be harmful to physical health, as people who rely on it tend to ignore symptoms of illness.
Early Relationships Shape Later Ones
- Dozens of studies support the idea that mental representations (or “internal working models”) of our parents and other significant figures shape our expectations for later friendships and romantic relationships (Mikulincer & Shaver, 2016). The claim that people choose romantic partners who physically resemble their parents is largely a myth—but research confirms that people do expect to be treated by others in ways that mirror their early caregiving experiences. A 2022 review of attachment theory by leading researchers found strong consensus that early attachment patterns influence relationship functioning across the lifespan, though attachment styles can also change through new relational experiences (Duschinsky et al., 2022).
