Stages of Freud's Model
-
Oral Stage (1-2 years):
- Focus: The mouth is the primary source of interaction and pleasure. Infants derive satisfaction from oral activities such as sucking, biting, and chewing.
- Developmental Task: The primary task during this stage is to develop trust and comfort through oral stimulation. Successful experiences lead to a sense of security.
- Example: Sucking on a pacifier or breastfeeding helps infants develop trust in their caregivers.
- Potential Outcomes: Fixation at this stage can lead to issues with dependency or aggression in adulthood. Individuals may develop oral-related habits, such as smoking or overeating.
-
Anal Stage (2-3 years):
- Focus: The anal zone becomes the primary source of pleasure. Children derive gratification from controlling bowel movements.
- Developmental Task: Toilet training is a significant aspect of this stage. The way parents handle toilet training can influence personality development.
- Outcomes:
- Overemphasis on Toilet Training: If parents are too strict or demanding, the child may develop an anal-retentive personality, characterized by compulsiveness, orderliness, and stubbornness.
- Lax Toilet Training: If parents are too lenient, the child may develop an anal-expulsive personality, leading to impulsiveness and a lack of organization.
-
Phallic Stage (3-5 years):
- Focus: The child becomes aware of their own genitals and develops sexual feelings. This stage is marked by the Oedipus complex in boys and the Electra complex in girls.
- Oedipus Complex: Boys develop an attraction to their mother and view their father as a rival for her affection. This leads to feelings of jealousy and fear of punishment (castration anxiety).
- Electra Complex: Girls experience a similar attraction to their father and may feel competition with their mother, leading to "penis envy."
- Developmental Task: Resolution of these complexes is crucial for developing a mature sexual identity and healthy relationships.
-
Latency Stage (6 years to puberty):
- Focus: Sexual feelings are repressed, and children focus on developing skills, friendships, and social interactions. This stage corresponds with the development of mixed dentition (the transition from primary to permanent teeth).
- Developmental Task: The maturation of the ego occurs, and children develop their character and social skills. They engage in activities that foster learning and peer relationships.
- Potential Outcomes: Successful navigation of this stage leads to the development of self-confidence and competence in social settings.
-
Genital Stage (puberty onward):
- Focus: The individual develops a mature sexual identity and seeks to establish meaningful relationships. The focus is on the genitals and the ability to engage in sexual activity.
- Developmental Task: The individual learns to balance the needs of the self with the needs of others, leading to the ability to form healthy, intimate relationships.
- Potential Outcomes: Successful resolution of earlier stages leads to a well-adjusted adult who can satisfy their sexual and emotional needs while also pursuing goals related to reproduction and personal identity.
Oedipus Complex: Young boys have a natural tendency to be attached to
the mother and they consider their father as their enemy.
