“Being able to focus, hold, and work with information in mind, filter distractions, and switch gears is like having an air traffic control system at a busy airport to manage the arrivals and departures of dozens of planes on multiple runways. In the brain, this air traffic control mechanism is called Executive Functioning, a group of skills that helps us to focus on multiple streams of information at the same time, and revise plans as necessary.” (The Center on the Developing Child at Harvard)
