Cognitive skills underlying the ability to plan, switch from task to task and resist tempting distractions usually matures by the time an individual turns 18 years old, a new study says.
presents some of the first definitive evidence that executive function -- a set of cognitive skills underlying the ability to plan, seamlessly switch from task to task, resist tempting distractions and focus on a task at hand -- usually matures by the time an individual turns 18 years old.
Unlike the meticulously mapped out milestones of childhood, the timeline of adolescence remained less formally defined, primarily due to the complexity of developmental processes set into motion with the onset of puberty. High variability among individuals and a lack of tools for analyzing complex datasets also limited the confidence of previous attempts to build a roadmap of brain development in teens.
The study collected 23 distinct measures of executive function from over 10,000 participants from 8 to 35 years old. Scientists then analyzed those metrics by tracking their change over time and checking whether performance across different tests fit a single trajectory that could be described with a mathematical model.
