Final answer:
Erik Erikson's theory indicates that identity is the basic strength that should develop during adolescence, where the main task for adolescents involves establishing a strong sense of self to avoid role confusion.
Step-by-step explanation:
According to Erik Erikson's theory of psychosocial development, the basic strength that should develop during adolescence is identity. During this critical stage of development, the main task for adolescents revolves around forming a sense of self and answering fundamental questions like "Who am I?" and "What do I want to do with my life?". This developmental challenge is labeled as identity versus role confusion. Successfully navigating this stage results in a strong identity, helping individuals remain true to their beliefs and values despite challenges. However, those who fail to actively seek out their identity or who succumb to external pressures may experience role confusion, leaving them with an unclear sense of their own identity and uncertain about their future.In conclusion, during adolescence, it's pivotal for individuals to develop their identity, allowing them to emerge with a robust sense of who they are. This serves as the foundation for building future relationships and making personal and vocational choices that align with their true self.
