What is the expected developmental task for an adolescent (ages 12-18) according to Erikson's stages of psychosocial development?

Erik Erikson's eight stages of psychosocial development describe normal developmental tasks across the lifespan. Stage 5 (12-18 years): Identity vs. Role Confusion — adolescents develop a sense of self and personal identity. Success leads to fidelity; failure to role confusion and weak sense of self. The eight stages: (1) Trust vs. Mistrust (infant, 0-18 months) — develop trust through reliable caregiving; (2) Autonomy vs. Shame/Doubt (toddler, 18 months-3 years) — develop independence in toilet training, walking, choice-making; (3) Initiative vs. Guilt (preschool, 3-5 years) — assert control through play and social interaction; (4) Industry vs. Inferiority (school age, 6-11 years) — develop competence through school and activities; (5) Identity vs. Role Confusion (adolescent); (6) Intimacy vs. Isolation (young adult, 18-40 years) — develop close relationships; (7) Generativity vs. Stagnation (middle adult, 40-65 years) — contribute to society and next generation; (8) Integrity vs. Despair (older adult, 65+) — reflect on life with sense of fulfillment. NCLEX commonly tests these stages because age-appropriate teaching and care depends on understanding developmental tasks.
