Executive Function
Executive function is the name for a set of mental skills that help you get things done. Planning, starting, organising, switching between tasks, keeping track of time, holding several steps in mind at once: all of these are executive function. Think of it as the project manager of the brain, the part that takes a task from "I need to do this" through "I am now doing this" and eventually to "it is done."
For many autistic and ADHD brains, the project manager is unreliable. Present some of the time. Absent on others. Willing to plan in great detail but somehow never getting to the starting part. Excellent at starting things but losing track of where they were. Great at the interesting bits, frozen at the administrative step that needs to happen before the interesting bit begins.
The homework sits there. The person sits there. There is no visible reason for the stall, and that is precisely what makes it so frustrating for everyone involved, including the person doing the stalling. They know they need to start. The knowledge is not the same as the ability to start.
This is called task initiation difficulty, and it is one of the most common executive function challenges. It is not laziness, and it is not stubbornness. It is a genuine difference in how the brain fires up a task.
Differences in executive function are common in autism: the largest meta-analysis to date (Demetriou and colleagues, 2018) found a consistent group-level effect across studies, with the majority of autistic people showing measurable differences on standard tests. The cluster of skills involved is wide: task initiation, working memory (holding instructions or steps in mind while using them), planning and sequencing, cognitive flexibility (adapting when plans change), time perception, and self-monitoring. Any one of these areas can be difficult; many people experience differences in several at once.
Two of the more counterintuitive manifestations are worth naming for parents and teachers.
The first is what is sometimes called task paralysis: not an unwillingness to do something but a genuine inability to start, even when the task is wanted or valued. The person is not making a choice to delay. The brain's initiation mechanism is stalled, and no amount of knowing the task is important dislodges the stall. The frustration of being told to "just start" when that is exactly what isn't working is considerable.
The second is the time perception problem. Executive function includes a sense of how long things take, how far away a deadline is, and how to work backward from a deadline to the steps needed to meet it. This sense is often inaccurate in autistic and ADHD people: time can feel either indefinite (the deadline feels far away even when it isn't) or telescoped (there's no sense that three hours have passed). Neither produces good planning outcomes, and neither is a choice.
What helps is externalising what the brain isn't reliably providing internally. Visual schedules make time concrete and visible. Timers make duration tangible. Checklists break a task into steps that don't need to be held in working memory all at once. Body-doubling, working alongside another person even in silence, lowers the activation threshold for many people in ways that are real and research-supported, though not yet fully understood. These tools do not fix the underlying difference; they work around it in ways that let the person function.
- Breaking tasks into small, concrete, separately listed steps rather than one large instruction.
- Using timers, visual schedules, and checklists as everyday scaffolding, not as a sign of failure.
- Not interpreting stalling as disrespect or laziness: asking "what would make starting easier?" rather than "why haven't you started?"
- Offering to work alongside the person (body-doubling) for hard-to-initiate tasks.
- "You just need to get on with it." (Getting on with it is the part that isn't available right now.)
- Removing supports once the person appears to be managing, as this is usually what was making the managing possible.
- Conflating executive function difficulty with lack of intelligence or capability.
- Expecting time management to come naturally when the internal clock is unreliable.
