Question 5

Adolescent risk-taking behavior, such as experimenting with substances or reckless driving, is often attributed to a developmental mismatch in the brain. Which of the following best describes this mismatch?

Accepted Answer

B. Rapid development of the limbic system (reward center) preceding the full maturation of the prefrontal cortex (judgment center). — The limbic system, responsible for emotions and reward processing, develops rapidly during adolescence, leading to increased sensation-seeking. However, the prefrontal cortex, crucial for judgment, impulse control, and long-term planning, matures later, creating a temporary imbalance that can contribute to risk-taking behaviors. The prefrontal cortex is not fully developed, and the cerebellum and brainstem play different roles.

Answer

A. Fully developed prefrontal cortex but underdeveloped limbic system.

Answer

C. Complete maturation of the cerebellum leading to impulsive actions.

Answer
