MedicalResearch.com Interview with: Brenden Tervo-Clemmens, Ph.D. Assistant Professor Department of Psychiatry & Behavioral Sciences Masonic Institute for the Developing Brain Scholar, Institute for Translational Neuroscience University of Minnesota MedicalResearch.com: What is the background for this study? Response:      Both contemporary and historical theories of neurobehavioral development suggest executive functions (EF) mature through adolescence. These are often used in various contexts to try to demarcate the developmental boundaries of the adolescent period. However, the specific maturational timing of executive function, and the independence of various potential executive function subcomponents remain unknown. Building from prior investigations with relatively small datasets or narrow subsets of executive function measures, this work using four independent datasets (N>10,000) and 17 distinct executive function assessments provides a precise charting, multi-assessment investigation, and replication of executive function development from adolescence to adulthood.
