Recall Erik Erikson's (1958) eight-stage model of psychosocial development.
Stage 1: Infants learn to trust or mistrust in the first 18 months of life. This experience of trust affects all later stages.
Stage 2: Independence/autonomy vs shame - as an infant explores new situations and environments, he or she takes risks and experiences failure. If criticised or over-controlled by caregivers, the infant's autonomy will be overwhelmed by shame.
Stage 3: Initiative vs guilt - from three to five years old, a child starts regularly interacting socially, which requires some assertiveness. If this is met with punishment or over-restriction, the child's initiative will be overwhelmed by guilt.
Stage 4: industry versus inferiority appears during the middle and late childhood.
