The Eide Neurolearning Blog has a great post that is about the development of neuropathways in executive functioning (though it refers to it as cognitive control).
An interesting post with good images that shows that adult like development is emerging soundly around age 9. This observation fits well with the norms of tests like D-KEFS where increased frequency in productivity tasks and a decreased rate of errors starts to appear around age 9-10. It also highlights that evaluation of executive impairment under this age (as can be done with NEPSY-II and by checklist form on BRIEF-P) should be interpreted with a caveat that this is a highly developmental characteristic and that borderline impairments my warrant revisiting after age 9.
