What the report covers

The report is a three-way comparison in developmental psychology. Freud's psychosexual stages, Erikson's stages of psychosocial development, and Piaget's stages of cognitive development are presented in turn, then lined up against one another.

A stage, in all three writers, is a qualitative shift, not just a year on a chart. What shifts is not the same thing.

Freud's psychosexual stages

Freud described oral, anal, phallic, latency, and genital stages. The claim is that the focus of drive and conflict moves, and that unresolved conflict can leave a lasting style of dealing with others.

In US undergraduate courses this model is usually taught as a historical foundation, not as a current diagnostic map. Students are expected to know the sequence and the idea of fixation, and also to know the limits: the evidence base is clinical and theoretical rather than experimental in the modern sense.

Erikson's stages of psychosocial development

Erikson, in Childhood and Society, recast development as a series of eight psychosocial crises, from trust versus mistrust in infancy to integrity versus despair in later life. Identity versus role confusion in adolescence is the chapter most often assigned in education programs.

The model is wider than Freud's in two ways. It runs through adulthood, and the conflict is social: the child or adult is negotiating a place with caregivers, peers, institutions, and a culture.

US K-12 talk about social-and-emotional learning often echoes industry versus inferiority (elementary competence) and identity work in high school, even when Erikson is not named.

Piaget's cognitive map

Piaget is here as a third axis. His stages describe how reasoning is reorganized. They do not tell you whether a child feels trustworthy, ashamed, or industrious. Mixing the charts into one ladder is the most common student error.

How to use the comparison in a paper

• Pick one age, then write three short portraits: drive and conflict (Freud), social crisis (Erikson), and thinking (Piaget).
• Show one overlap clearly: early feeding and care appear in Freud's oral stage and in Erikson's trust versus mistrust, but only Erikson makes the caregiver relationship the name of the crisis.
• State the limits. Freud's evidence is not a modern randomized study. Erikson's crises can be hard to measure. Piaget underplayed culture and instruction.
