Key Concept: Egocentrism Type

b) Imaginary audience

[Solution Description] Adolescents often develop a form of egocentrism known as the imaginary audience, where they believe that all eyes are on them, leading to heightened self-consciousness.

Key Concept: Moral Reasoning Evolution, Cognitive Development Influence

c) It allows consideration of abstract principles

[Solution Description] During adolescence, increased cognitive capabilities allow for abstract thinking and hypothetical-deductive reasoning. These developments enable youths to critically evaluate rules, consider broader ethical principles, and understand the implications of actions beyond immediate consequences. This cognitive growth moves them from rule-based thinking (common in childhood) towards principle-based reasoning characteristic of more advanced stages like the Post-conventional level.

Key Concept: Development Sequence

c) Proximodistal trend

[Solution Description] The principle that describes the pattern of growth where development proceeds from the central part of the body towards the extremities is called the Proximodistal trend. This means that infants first gain control over parts closer to the center, like the torso, before gaining control over the arms.
