Executive Functions are needed all day , every day. They include skills like planning ahead, being organized, tieing shoelaces, packing a bag, even writing a sentence.
Executive Function is frequently delayed in children with learning disorder (eg. dyslexia, dysgraphia) or other neuroeiversities such as ADHD and ASD.
Dr. Kathryn Garforth is one of my favorite teacher of executive functions. She is extremely knowledgeable and explains difficult concept really well.
