Final answer:
The transition from adolescence to young adulthood is characterized by stable identity formation, which is part of the psychosocial changes involving increased autonomy and a focus on peer relationships.
Step-by-step explanation:
The transition from adolescence to young adulthood is characterized by the development of a stable identity formation. During the adolescence period of transition, individuals undergo significant psychosocial changes, which include a stronger sense of personal identity and a personal system of moral and ethical values. According to Erikson's theory of psychosocial development, a key task during adolescence (ages 12-18) is developing autonomy and a sense of self, which enables individuals to answer questions like "Who am I?" and "What do I want to do with my life?" As adolescents mature, they experience increased autonomy, emotional separation from parents, and a shift in focus towards peer relationships. These changes support the idea that the passage into young adulthood involves stable identity formation rather than continued dependence on parental guidance or unchanged emotional regulation.
