Final answer:
Adolescence, according to Erik Erikson's theory, is focused on the establishment of a sense of identity, where teens explore different roles and ideas to define themselves.
Step-by-step explanation:
According to Erik Erikson's theory of psychosocial development, adolescence is regarded as the period associated with the establishment of a sense of identity. In adolescence (ages 12-18), the developmental task that individuals face is identity versus role confusion. This phase involves adolescents asking pivotal questions such as "Who am I?" and "What do I want to do with my life?" It's a time where they explore various roles and ideas to establish their personal identity and values. Successfully navigating this stage leads to a strong sense of self, while failure can result in role confusion and a weak sense of identity.
