Which of the following best describes changes in executive function during middle childhood and adolescence?

• A. Executive function remains stable from childhood through adolescence.
• B. Executive function declines during adolescence.
• C. Improvements in working memory, cognitive flexibility, inhibitory control, planning, and goal-directed behavior; adolescence shows continued maturation of prefrontal circuits, with improvements in risk assessment and decision-making.
• D. Executive function is limited to motor planning only.

Answer: (C)

Executive function develops across middle childhood into adolescence, with broad improvements across several domains. As children grow, working memory, cognitive flexibility, inhibitory control, planning, and goal-directed behavior all become more accurate and strategic. This reflects continued maturation of prefrontal circuits, which supports better attention control, error monitoring, and the ability to weigh risks and make more deliberate decisions. That’s why the best description is ongoing, multi-domain enhancement rather than stability, decline, or restriction to motor planning.
