Why can my child know what to do and still not do it?

The short answer

Knowing a task and carrying it out draw on different processes. The child may need to notice the cue, stop another activity, hold the goal in mind, choose a first action, organise materials, estimate time, resist competing attention, monitor progress and recognise when the task is finished. A difficulty at any point can look like refusal, laziness or lack of motivation. Executive function is an umbrella for several of these processes, not one ability that a child either has or lacks, and it does not explain every unfinished task. Check understanding, skill, sensory and emotional load, sleep, health, task meaning and the child's account. Then move one demand out of the child's head: show the first step, prepare the materials, make time visible or work nearby. Keep the outcome clear while testing what makes action possible.

• Understanding an instruction does not guarantee access to every process needed to carry it out.
• Executive function covers several related processes and can vary by task, setting, development and current capacity.
• An unfinished task does not reveal whether the child did not care, chose not to act or could not organise action.
• Check skill, communication, sensory load, anxiety, sleep, health and environment before settling on an executive explanation.
• External supports can increase independence by making information and cues available at the point of action.
• Hold necessary boundaries while changing timing, method, prompting and support.
