How do executive functions develop during adolescence and how do they relate to decision-making?

• A. Decrease in working memory over adolescence
• B. Inhibitory control becomes worse
• C. Improvements in working memory, inhibition, cognitive flexibility; better planning and impulse control support safer decision-making
• D. Executive function does not relate to decision-making

Answer: (C)

Executive functions, including working memory, inhibition, and cognitive flexibility, develop throughout adolescence and shape how decisions are made. As these processes mature, teens get better at holding and manipulating information in mind (working memory), resisting impulses (inhibition), and adapting to new rules or shifting strategies (cognitive flexibility). This growth supports more deliberate planning, better anticipation of consequences, and greater self-control, all of which contribute to safer, more considered decision-making. Behind the surface, this development mirrors brain changes in the prefrontal cortex and its connections with emotional and reward systems, helping the mind balance immediate urges with longer-term goals. It’s also normal for risk-taking to persist during adolescence, because reward-related circuits can be highly active even as control mechanisms strengthen, but the overall trend is toward improved planning, impulse control, and flexible thinking that support better choices. The idea that working memory declines, or that inhibitory control worsens, doesn’t align with what we know about adolescence. And saying executive function isn’t related to decision-making ignores how these cognitive controls underlie weighing options, predicting outcomes, and controlling actions.
