What Is Executive Function? 7 Deficits Tied to ADHD

What is executive function? The cognitive skills that help us plan, prioritize, and execute complex tasks are commonly tied to ADHD in children and adults. Here, ADHD authority Russell Barkley, Ph.D. explains how executive dysfunction originates in the ADHD brain and what these deficits typically look like.

What Is Executive Function?

Executive function is the cognitive process that organizes thoughts and activities, prioritizes tasks, manages time efficiently, and makes decisions. Executive function skills are the skills that help us establish structures and strategies for managing projects and determine the actions required to move each project forward. Individuals with executive dysfunction often struggle to analyze, plan, organize, schedule, and complete tasks at all — or on deadline. They misplace materials, prioritize the wrong things, and get overwhelmed by big projects.

Is Executive Dysfunction a Symptom of ADHD?

There’s a lot of confusion around “executive function” — and how it relates to ADHD. Is ADHD an executive function disorder? Is every executive function disorder also ADHD? The answers hinge on what we mean by “executive functions” — and how they relate to self-regulation.

The term “executive functioning” was coined in the 1970s by Karl Pribram, whose research indicated that the executive functions are mediated primarily by the prefrontal cortex. Traditionally, it’s been used extensively in neuropsychology, clinical psychology, and psychiatry. In recent years, however, it’s spread into the broader field of general psychology and into education, where it’s often incorporated into teaching strategies and classroom accommodations.

So far, we know about four circuits in prefrontal cortex of the brain that relate to executive function — and executive dysfunction.

Executive Function and the ADHD Brain

The “What” Circuit: Goes from the frontal lobe — especially the outer surface — back into an area of the brain called the basal ganglia, particularly a structure called the striatum. The “What” Circuit is linked to working memory, so it’s in this circuit that what we think starts to guide what we do. This is particularly true when it comes to plans, goals, and the future.

The “When” Circuit: This second circuit goes from the same prefrontal area back into a very ancient part of the brain called the cerebellum, at the very backmost part of your head. The “When” Circuit is the timing circuit of the brain — it coordinates not just how smooth behavior will be and the sequence of behavior, but also the timeliness of your actions and when you do certain things. An improperly functioning “When” Circuit in a person with ADHD explains why we often have problems with time management.

The “Why” Circuit: The third circuit also originates from the frontal lobe, going through the central part of the brain (known as the anterior cingulate) to the amygdala — the gateway to the limbic system. It’s often referred to as the “hot” circuit because it’s linked to our emotions — it’s where what we think controls how we feel, and vice versa. It’s the final decision maker in all our plans. When thinking about multiple things we could be doing, this is the circuit that eventually chooses among the options based on how we feel about them and their emotional and motivational properties.

The “Who” Circuit: This final circuit goes from the frontal lobe to the very back of the hemisphere. It’s where self-awareness takes place — it’s where we’re aware of what we do, how we feel (both internally and externally), and what’s happening to us.

By viewing ADHD in relation to these four circuits, you can understand where symptoms originate. Depending upon which circuits are most impaired and least impaired, you can see variation in the kinds of symptoms that any individual is going to have. Some people have more working memory deficit. Some people have more emotion regulation problems. Some people have more difficulties with timing, but less difficulties with all the others. But they all involve these circuits.

What Are the Core Executive Function Skills?

So we know what parts of the brain control executive functions, but what are they specifically? Broadly speaking, executive function refers to the cognitive or mental abilities that people need to actively pursue goals. In other words, it’s about how we behave toward our future goals and what mental abilities we need to accomplish them.

The term is very closely related to self-regulation — executive functions are things you do to yourself, in order to change your behavior. By employing your executive functions effectively, you’re hoping to change your future for the better.

Executive function is judged by the strength of these seven skills:

1. Self-awareness: Simply put, this is self-directed attention.

2. Inhibition: Also known as self-restraint.

3. Non-Verbal Working Memory: The ability to hold things in your mind. Essentially, visual imagery — how well you can picture things mentally.

4. Verbal Working Memory: Self-speech, or internal speech. Most people think of this as their “inner monologue.”

5. Emotional Self-Regulation: The ability to take the previous four executive functions and use them to manipulate your own emotional state. This means learning to use words, images, and your own self-awareness to process and alter how we feel about things.

6. Self-motivation: How well you can motivate yourself to complete a task when there is no immediate external consequence.

7. Planning and Problem Solving: Experts sometimes like to think of this as “self-play” — how we play with information in our minds to come up with new ways of doing something. By taking things apart and recombining them in different ways, we’re planning solutions to our problems.

Does this list sound familiar? It should. Anyone who exhibits the classic symptoms of ADHD will have difficulty with all or most of these seven executive functions. Problems with inhibition in someone with ADHD lead to impulsive actions, for example. Problems with emotional regulation lead to inappropriate outbursts.

Essentially, ADHD is an executive function deficit disorder (EFDD). The umbrella term “ADHD” is simply another way of referring to these issues.

These seven executive functions develop over time, in generally chronological order. Self-awareness starts to develop around age 2, and by age 30, planning and problem solving should be fully developed in a neurotypical person. Those with ADHD are generally about 30 to 40 percent behind their peers in transitioning from one executive function to the next. Therefore, it makes sense for children and adults with ADHD to have trouble dealing with age-appropriate situations — they’re thinking and acting in ways that are like much younger people.

Awareness of these executive functions can help parents set up an early detection system for ADHD, helping them to seek a professional evaluation and accommodations before a child begins to struggle in school. Then, with proper accommodations and treatment, people with ADHD can learn to use what they know and strengthen these executive functions over time.

  1. Fascinating and, in a weird way, to me, comforting. Here’s why: the best resource I’ve read in this space is John Perry’s THE ART OF PROCRASTINATION. ADHD aren’t the only folks attempting to cope with executive deficits.

    I self-diagnosed at age 57 and have accomplished (once i do the gratitude thing and give myself a little breathing space!) far more than most ‘average’ folks…but on very different timelines.

    My career (a misnomer: I’ve led multiple working lives) is only now peaking, largely due to serious remaking of my brain via daily meditation and daily lengths swims. In other words, there are real blessings w/ADHD, not least of which is harnessing hyperfocus and a life energy generally far higher than ‘average’.

    There’s something to the belief that while there are real causes for life-management concern, we ADHDers ain’t the only folks behind in our tax filings (say) or losing our keys or addicted to toxic distractions. This isn’t empty consolation: I have to remind myself that I’m a human with all my strengths and weaknesses but with ADHD…not an ADHDer with faults and glitches and function-errors that mean I’m less than fully human.

    Also: I find a ‘poem a day’ service really focusing; Brainpickings and The Paris Review and poetry.com all have one 😉

  2. I found the article well written and helpful. However, I would love for the tone of these discussions to move away from terms like deficiency, deficit, dysfunction. Why not focus on the benefits and the awesome positive sides to people who have these tendencies?! There are so many different people in the world, all with different ways of thinking, we all have different strengths and things we can work on to improve our lives and/or academic success. The constant negative wording; deficit, dysfunction, disorder being stated around, or about young children, who are yet to master a skill, locks them in a box rather than freeing them. A victim mentality is more likely to be perpetuated from a young age, as concerned parents try to support their children, but are constantly talking about their children’s weaknesses, what their children struggle with around them. It’s just showing young children that they are ‘less than’. As adults talking about our children, we could take a more positive approach, “This is a skill you have yet to master. This is why this skill is important. These are things we can work on to help you strengthen this skill.” Focus on and find out the benefits to being scatterbrained – you are more like to be able to multi task and complete a lot of things over a course of a day. Way more empowering to find the ‘strength’ to your ‘weakness’ and to use it for good.

  3. @Melfunction There is a great video on YouTube, “Dr. Russell Barkley ADHD is not a gift”. I suggest you go and watch it before saying that ADHD should be treated as a positive thing. Some people may have grown up in a positive and supportive environment that did not break their self-worth because of the consequences and behavioural issues that come with ADHD.And yes, in day to day life, people interacting with ADHD children should acknowledge the areas of impairment and, being positive, work with the child to find compensothem strategies that are based on the child abilities. But on a official, medical, legal, regulations, whatever point of view, you shouldn’t glorify ADHD. It undermine the real day to day struggle most people have to content with. So when you’re done with the first video head on to “Dr. Russell Barkley – ADD, ODD, emotional impulsiveness,and relations”. Then, please take a look at the comments section for testimonies about how ADHD is not a gift, although you can have ADHD and be gifted. Another argument Dr.Barkley makes, which you should also consider, is, if you take away the deficit components, you take away the possibilities of help and research. Why should the government, educational system, social welfare, medical field work on providing specific help, accommodations, guidance for people who suffer from ADHD if it’s not a disorder, but a gift?! I believe that in real life situations, working with kids, you should always acknowledge their difficulties, only then will the child feel validated in their struggles and maybe help them understand why they struggle when their friends or classmates don’t (or maybe not in the same way), and from there on work with each individual child’s strengths to formulate personal strategies to help them cope with life. I hope you will not take my comment badly, but as I child who, unfortunately follows statistics, and was always blamed for the symptoms of my ADHD, made out to be the bad child because of the expressions of my deficits, it hurts to hear people glorify ADHD. I’m considered smart, was tested, high IQ, potentially High Intelligence Potential and yet I have not been able to “succeed in life”, I crashed and burned in university because I had never learned how to study and I was in a demanding course. When people tell me I’m smart, skilled, capable my first thoughts are always “So what?! It’s never helped me.” Because even though I got diagnosed, I didn’t get treatment until I failed university, even though I loved my courses, and remembering the diagnosis went and seeked out help on my own. But by then, a lot of damage had already been done. Ten years later, I have a long list of comorbidities and other medical issues and still no accomplishments to show for my “giftedness”.
