Question 1

A high school counselor observes that many adolescents engage in impulsive, risky behaviors despite understanding the potential negative consequences. Which of the following best explains this phenomenon from a neurodevelopmental perspective?

Accepted Answer

B. The limbic system, associated with emotion and reward, matures earlier than the prefrontal cortex. — Neuroscientific research indicates that the limbic system, responsible for emotions, rewards, and impulsivity, develops and matures earlier in adolescence compared to the prefrontal cortex, which is responsible for executive functions like planning, impulse control, and risk assessment. This developmental imbalance can lead to a period where adolescents are more prone to impulsive and risky behaviors, as the emotional drive often overrides nascent rational control.
