Final answer:
Deano is most likely experiencing identity diffusion, which aligns with Erikson's concept of an adolescent lacking direction and commitment in developing a personal identity.
Step-by-step explanation:
Based on Erikson's stages of psychosocial development, Deano, who is attracted to novelty and risk-taking, has a poor relationship with his parents, and feels invincible, may be at risk for identity diffusion.
This is when an adolescent does not make a conscious effort to develop a sense of self, resulting in a weak sense of identity and confusion about the future. Identity diffusion is characterized by a lack of direction and commitment regarding personal beliefs and occupational choices. Deano's behavior suggests that he has not yet committed to a certain identity or set of values, which matches the description of identity diffusion.
