Your teenage daughter has just come home from school in tears — she tells you that she hasn’t submitted her history essay (the one she worked hard on all weekend), and that her teacher is assigning her a late penalty of 10% off each day. With a bit of prompting, you discover that the essay is done except for the bibliography. You don’t understand – how could she get so close to the finish line, only to give up at the last minute? Frustrated, you can’t help but think: “Why can’t she just find the willpower to get it done?”
The truth is, your daughter likely wants to finish that essay even more than you want her to. What looks like a lack of willpower is actually a struggle with goal-directed persistence (GDP).
Goal-directed persistence is the executive function that allows us to stay the course until a task is 100% complete, even when the initial excitement has faded. For many children and teens with ADHD, the brain’s “mental fuel” runs out just as they reach the final stretch. Understanding why this happens is the first step in moving away from frustration and toward a plan that actually works.
What is goal-directed persistence
Simply put, goal-directed persistence is the ability to set a goal and ‘stick with it’ until completion, even when the task is boring, challenging, or time-consuming. It is often one of the last executive function skills to develop and mature in the brain, because it requires the ability to coordinate multiple other executive function skills, such as task initiation, self-regulation, and attentional control.
Challenges with goal-directed persistence are often misinterpreted as a lack of motivation or willpower. In reality, there is often a neurological gap between a child’s intention and their actions. This is why many children with ADHD find it difficult to follow through, even on goals that they deeply care about. This struggle isn’t about a lack of desire, but rather a difference in brain chemistry.
Different nervous systems
We can use Dr. William Dodson’s framework of the interest-based nervous system versus the importance-based nervous system to better understand how ADHD brains work.
The Importance-Based Nervous System
Most neurotypical individuals operate on an importance-based nervous system. They are generally motivated by how important the task is to them or to other people in their lives, like their parents or teachers. Future rewards or consequences for completing or not completing the task can also be highly motivating for them. The importance-based nervous system helps individuals to prioritize tasks based on external pressures and a sense of responsibility.
The Interest-Based Nervous System
The ADHD brain operates on an “interest-based” rather than importance-based nervous system. A child with ADHD might fully understand why a task is important, but still struggle to stay engaged. This is due to lower levels of dopamine, the neurotransmitter responsible for feelings of pleasure and reward for completing tasks. To produce enough dopamine to follow through on a task, the ADHD brain requires one of four specific motivators: novelty, interest, challenge, and urgency. Without these factors, goal-directed persistence can feel like an uphill battle for a child with ADHD.
The four dopamine triggers
To a child with an interest-based nervous system, importance is a weak ‘fuel source’ for their brain. In order to persist towards a goal, they require one of four key dopamine triggers.
INTEREST
When a child is highly interested in a topic or activity, their brain is able to stay focused without much external effort. This is why your child can spend hours drawing, playing their favourite video game, or reading about outer space – but struggles to sustain their attention for ten minutes of math homework.
NOVELTY
The ADHD brain craves the new and novel. Your child might be incredibly enthusiastic about their new planner and use it consistently for two weeks – before suddenly losing interest and abandoning it. Once the sense of novelty is gone, the brain is no longer receiving enough dopamine to keep your child engaged.
CHALLENGE
Many kids and teens with ADHD can be highly competitive or driven by a sense of mastery. You might notice that your child works best when they are trying to “beat their high score”, or prove that they can do something difficult. If a task feels too easy (and therefore boring), or too impossibly hard, that spark of motivation often disappears.
URGENCY
A sense of urgency can be incredibly motivating, but relying on this trigger too often can create a great deal of stress for your child. You may find that your child often starts writing their research paper the night before it’s due. This isn’t necessarily because they forgot about the assignment. Instead, the looming deadline creates a spike of stress-induced dopamine that finally allows their brain to engage. While this is effective in the short term, relying on urgency can often lead to a cycle of anxiety and burnout.
What does a struggle with GDP look like?
Younger Children
- The Half-Finished Trail: Your child’s bedroom floor may be covered in half-finished Lego creations, partially coloured pages, or board games abandoned halfway through because they “got bored”.
- The Homework Battle: Even if the homework assignment is easy for your child, they rely on you sitting next to them, providing a constant stream of encouragement, negotiation, and reminders to stay focused until the worksheet is done.
- Meltdowns Over Obstacles: When your child hits a small snag, such as a broken pencil or a word they don’t know how to spell, they might ‘shut down’, becoming dysregulated and refusing to continue.
Teenagers
- The Last 10% Struggle: Your teen might spend hours planning, researching and writing their history paper, only to get stuck on the final pieces, like editing or even submitting their work.
- The Cycle of Hobbies: Your teen might dive headfirst into a new interest, buying all the gear and learning everything they can about a new sport, musical instrument, or hobby – only to lose interest a few weeks later once the novelty has worn off.
- Living in the “Now”: Because of their interest-based motivation system, your teen might neglect working on their long-term goals in favour of activities that provide immediate gratification. Even if they deeply desire to get into a specific university program, they might spend their evenings watching Youtube videos or gaming rather than studying.
Why GDP matters for future independence
In early childhood, parents and teachers provide ‘scaffolding’ to support children in setting and persisting towards goals. These supports come in the form of external rewards, reminders, and prompts to keep the child on track.
As children grow into teens and young adults, these external supports naturally begin to fade away and the job of managing one’s responsibilities and day-to-day tasks shifts to the individual. Goal-directed persistence is a crucial skill that allows children to grow into independent, self-sufficient adults.
Strategies for building persistence
There are many ways to support children and teens in developing their goal-directed persistence. Dr. Dodson’s interest-based nervous system framework can help us identify strategies that actually work for your child.
INTEREST
Where possible, find ways to make boring tasks more interesting.
- Pair a boring task with an exciting one, like putting on their favourite music or an exciting audiobook while they tidy their room.
- Help them to choose a topic that genuinely interests them for their research project.
- Find ways to make a mundane task more playful. Get your child to jump rope or bounce a basketball while practicing their spelling words, or take them outside to practice their addition facts with sidewalk chalk.
NOVELTY
Switch up the environment or method of completing a task
- Homework doesn’t always need to be done at the kitchen table – what if your child finished their reading homework in a blanket fort, in the bathtub, or even just in a different room? Maybe your teen would enjoy studying at the local cafe or library.
- Offer your child a choice of colourful stationery, scented markers, and fun sticky notes to add novelty to homework time.
CHALLENGE
Turn routine tasks into a challenge or competition to get the needed dopamine boost
- Use a timer to see how quickly your child can put away their toys, and challenge them to beat their score the next time.
- For younger children, frame tasks as “secret missions” – challenge them to complete five math problems before you finish folding a load of laundry, or ask them to report back to “headquarters” with three facts they learned from their assigned reading.
- There are also many apps and digital learning tools that help to gamify learning. Apps such as Kahoot and Blooket can turn studying into an interactive quiz game. For older students, the Habitica app turns daily habits and routines into an exciting role-playing game.
URGENCY
Set up intentional, low stakes deadlines to create a sense of urgency without needing to relay on last-minute panic
- For a larger project, you can help your child to create mini-deadlines for each individual step (e.g. choosing a topic, collecting research, writing a first draft, editing their work) and have them check in with you each day to report their progress. Increase your child’s ‘buy-in’ by rewarding them for each deadline that they have successfully hit.
- Using timers is a great way to incorporate a sense of urgency into any activity.
- The Pomodoro method can help to break up a longer task into shorter, more ‘urgent’ bursts of effort.
How executive function coaching can help
The goal of executive function coaching is to support your child in building the internal systems they need to reach the finish line on their own.
It can be exhausting to watch your child or teen struggle to cross the finish line, especially when you know how much potential they have. Fortunately, goal-directed persistence is like a muscle that can be strengthened over time. With supportive, targeted coaching and opportunities to experience success, your child will learn that they are capable of achieving whatever goals they set their mind to.
