According to Erik Erikson, developmental stages are trust versus mistrust (birth to 18 months), autonomy versus shame and doubt (18 months to age 3), initiative versus guilt (ages 3 to 5), industry versus inferiority (ages 5 to 12), identity versus identity diffusion (ages 12 to 18), intimacy versus isolation (ages 18 to 25), generativity versus stagnation (ages 25 to 60), and ego integrity versus despair (older than age 60).
