Executive functioning and many components have been ambiguous concepts due to the lack of specificity and the lack of an agreed-upon definition. Dr. Russell Barkley is ready to change all that. He has constructed a new, more precise definition that acts metaphorically as a Swiss army knife cutting through the ambiguity, bringing clarity to what is and is not an executive function. With this in hand, he has conceptualized a new model of executive functioning as an extended phenotype. This new model shows why adult ADHD is a disorder of executive function. Even if most adults with ADHD are not impaired on neuropsychological tests of executive function. His new model has some very interesting implications for the assessment and management of executive function deficits as they exist in adults with ADHD. In this episode, host, Jeff Copper, discusses with Dr. Barkley this new construct in basic terms and discusses how the model would improve the assessment and management of ADHD moving forward.
