According to Erik Erikson, the primary task in adolescence is development of

Ego integrity is a concept associated with Erikson's later stage of development, specifically in old age, where individuals reflect on their lives. It is not relevant to the adolescent stage, which focuses on identity exploration rather than reflecting on past experiences.

While self-esteem is important during adolescence, it is not the primary developmental task according to Erikson. Self-esteem can be influenced by the successful resolution of identity issues, but it is a byproduct rather than the core focus of this developmental stage.

Self-concept refers to how individuals perceive themselves and can be a component of identity. However, Erikson emphasizes identity as the overarching task in adolescence, with self-concept being one aspect that develops as part of the identity formation process.

Autonomy is crucial during adolescence as individuals seek independence, yet it is not the primary task identified by Erikson. Autonomy supports identity development but does not encapsulate the complete essence of the adolescent experience as identity does.
