How does the brain develop during adolescence and how does this relate to risk-taking?

• A. The prefrontal cortex matures slowly; the limbic system is more active during adolescence, leading to higher risk-taking; decision-making improves with experience
• B. The brain fully matures by age 12
• C. The limbic system is less active during adolescence
• D. Risk-taking decreases as the brain stops developing

Answer: (A)

Adolescence involves uneven brain development that affects how risk is weighed. The prefrontal cortex, which helps with planning, weighing consequences, and controlling impulses, matures more slowly and continues developing into the early twenties. Meanwhile, the limbic system—involved in emotions, motivation, and reward—often remains highly reactive during adolescence. This combination means teens can feel strong urges and seek rewarding experiences, but their ability to fully foresee long-term consequences and regulate impulses isn’t fully online yet. With experience and continued maturation, the prefrontal regions strengthen their connections and improve decision-making, which often reduces risky choices as they move into adulthood. This explains why risk-taking tends to be higher in teens but does not align with the idea that the brain stops developing early or that risk-taking disappears once development pauses.
