Joel Nigg, Ph.D., Oregon Health and Science University
Executive functioning (EF) emerges in precursive form very early in development, then consolidates gradually throughout childhood and adolescence. Its development both relies on, and provides a crucial context for, the development of numerous other abilities including language, emotion regulation, and learning. Therefore damage to this system early in development can be seen as a primary gateway for multiple forms of psychopathology, including ADHD, conduct disorder, mood and anxiety disorder, and learning disorders. The distinct ways in which EF may contribute to these diverse outcomes via moderation and mediation effects and developmental cascades are considered conceptually here.
