Erikson's Psychosocial Stages

Erik Erikson proposed that human development unfolds across eight distinct stages, each defined by a psychosocial crisis — a normative tension between a syntonic (healthy) and a dystonic (unhealthy) outcome. Unlike Freud, who viewed development as essentially complete by adolescence, Erikson extended his framework across the entire lifespan, from the first year of life through old age. Each crisis must be navigated — not resolved once and for all — and the way each is handled leaves a lasting mark on personality and wellbeing.

Marcia's Identity Status Theory

James Marcia built directly on Erikson's fifth stage — Identity vs Role Confusion — to create a more operationalised, empirically testable model of adolescent identity development. Where Erikson described the crisis in broad terms, Marcia identified four distinct ways in which individuals navigate it, based on two key dimensions: exploration (active questioning and searching across identity domains) and commitment (the degree to which an individual has made stable, self-defining choices).
