Final answer:
In Erikson's theory, individuals focus on developing identity during adolescence and intimacy during young adulthood. Adolescents work on identity versus role confusion, and young adults on intimacy versus isolation, where the success in the former stage impacts the latter.
Step-by-step explanation:
In Erikson's theory, individuals generally focus on developing identity during adolescence and then intimacy during young adulthood. The correct answer to the question is that during adolescence, the focus is on identity versus role confusion, as adolescents struggle with questions like "Who am I?" and "What do I want to do with my life?" They explore various roles and ideally form a strong sense of self. Following this, in young adulthood, the task is intimacy versus isolation, where the individual, now with a well-established identity, seeks to form meaningful intimate relationships with others. A lack of successfully developing a positive self-concept in adolescence can lead to emotional isolation in adulthood.
