Key Concept: Each of Erikson's eight psychosocial stages is tied to both an age range and a defining central conflict.
Why it's correct: Identity vs. role confusion is the fifth stage, occurring during adolescence (roughly ages 12–18), when individuals actively explore their personal identity and values.
Why others fail: Early childhood, young adulthood, and middle adulthood are each governed by a different Erikson stage with a different central conflict (e.g. autonomy vs. shame, intimacy vs. isolation) — not identity vs. role confusion.
