Erikson's Psychosocial Stages

Erik Erikson's eight-stage model of lifelong psychological development, each defined by a central crisis: Trust vs. Mistrust (infancy), Autonomy vs. Shame (toddler), Initiative vs. Guilt (preschool), Industry vs. Inferiority (school age), Identity vs. Role Confusion (adolescence), Intimacy vs. Isolation (young adulthood), Generativity vs. Stagnation (midlife), and Integrity vs. Despair (late life). Each stage presents a developmental challenge; successful resolution produces a virtue (hope, will, purpose, competence, fidelity, love, care, wisdom). Unresolved stages create developmental deficits that affect all subsequent stages.

When to use it

When understanding life transitions and the developmental challenges they present; when career dissatisfaction maps to a developmental crisis rather than a practical problem; when leadership needs to account for different developmental stages in team members; when long-term personal development planning needs a framework.

How it can help

Use the framework diagnostically: which stage's challenge is most active for you right now? Midlife professionals most commonly face Generativity vs. Stagnation (am I contributing beyond myself?) and may carry unresolved issues from Identity (who am I beyond my role?) or Intimacy (can I be genuinely close to others?). For leadership: understanding which developmental stage your team members are navigating helps you support them appropriately—a young professional working on Identity needs different support than a mid-career professional working on Generativity. For self-development: identify your unresolved earlier stages and address them—they're limiting your current development.
