What developmental mismatch helps explain why adolescents may engage in risk-taking?

• A. Brainstem maturation halting
• B. Cerebellum fully develops first
• C. Limbic system matures earlier than the prefrontal cortex (executive control), increasing susceptibility to reward
• D. Prefrontal cortex earlier

Answer: (C)

Adolescent risk-taking is best explained by a mismatch in brain development: the limbic system, which drives reward and emotion, matures earlier than the prefrontal cortex, which governs executive control like planning and inhibiting impulses. When reward circuits are highly responsive while self-control networks are still maturing, teens feel strong urges to seek new, salient experiences but have a less developed ability to weigh long-term consequences or regulate impulses. This combination naturally elevates risk-taking. The other options don’t fit because they don’t describe the timing difference between emotional/reward processing and higher-order control that creates this vulnerability.
