Question 1

A group of 17-year-olds decides to try a dangerous stunt they saw online, despite knowing the potential risks. When questioned, they downplay the dangers and focus on the thrill. This tendency among adolescents to engage in risky behaviors, often underestimating negative consequences and overestimating immediate rewards, can be partly attributed to the ongoing development of which brain region?

Accepted Answer

C. Prefrontal cortex — The prefrontal cortex, responsible for executive functions like planning, impulse control, risk assessment, and decision-making, continues to mature throughout adolescence and into early adulthood. Its incomplete development during the teenage years can lead to a greater propensity for risk-taking and a less developed ability to weigh long-term consequences against immediate gratification.
