Answer:
The form of adolescent egocentrism that Elkind might use to describe Marcus' view of the world is the invincibility fable.
Explanation:
According to psychologist David Elkind, the invincibility fable is most common in teenagers. It is a feeling of indestructibility, a sense of oneself as immune to injuries or consequences. The cause of the invincibility fable is the fact that, in teenagers, the development of the frontal lobe is still incomplete. It is this part of the brain that is responsible for the understanding of consequences. Marcus, as seen in the passage, is engaging in risky behavior because he does not think he will get caught. He is a typical example of the invincibility fable.
