When Writing Uses All the Brain: Why Automaticity Matters

Writing is often described as a basic school skill, something children are simply expected to “pick up” along the way.
But for many children, writing never becomes automatic. And when that happens, learning itself becomes harder.

Automaticity in writing is the ability to write fluently and naturally, without having to consciously think about every single movement. When writing is automatic, the hand follows the thought. The child can focus on what they want to say, rather than how to form each letter or word.

When automaticity is missing, writing absorbs a huge amount of mental energy. And that energy is no longer available for thinking, organising ideas, or expressing meaning.

From decoding to encoding

Reading and writing rely on different cognitive processes.

In reading, children work on decoding: recognising letters, connecting them to sounds, and extracting meaning from written words.

Writing requires the opposite process: encoding.
The child starts from an idea, a sound, or a thought and must transform it into graphic symbols: letters, spacing, words, and lines on a page.

This reverse process is cognitively demanding. For children with learning differences, difficulties in reading and writing often coexist precisely because these processes are so closely connected.

When writing never becomes automatic

Some children struggle to develop automaticity in writing because the mechanics of writing remain effortful for too long.

This may involve:

  • handwriting that is slow, irregular, or hard to read
  • difficulties with spelling and sound-to-letter conversion
  • problems organising words and space on the page

Beyond diagnostic labels, what matters is the functional impact.

When writing remains hard work, children often avoid writing, produce very short texts, simplify their ideas, and gradually lose confidence in their ability to express themselves.

Not because they lack ideas, but because writing blocks access to them.

When the hand can’t keep up with the mind

One of the most common situations I have observed over the years is this:

The child’s thinking moves faster than their hand.

During dictations, written exercises, or free-writing tasks, the child knows what they want to say. But the effort required to write each word slows them down so much that parts of the sentence are skipped, words are omitted, and ideas are lost halfway through.

The result is often a fragmented or incomplete text that does not reflect the child’s real understanding.

Many children say, “I didn’t know what to write.”
Very often, the real issue is: “I couldn’t write fast enough to follow my thoughts.”

Over time, this gap between thinking and writing can seriously affect motivation and self-esteem.

When rereading doesn’t help

Writing is not a linear process.
We write, reread, adjust, correct, and refine, often while the text is still being produced.

Rereading is a crucial part of writing. It allows the writer to check whether a sentence makes sense, whether something is missing, or whether an idea needs to be rephrased.

But for children whose handwriting is hard to read, this essential step becomes unreliable, or disappears altogether.

When writing is illegible, the child cannot easily reread their own text. Letters blur together, spacing is unclear, and words lose their shape. The page no longer supports thinking; it becomes another problem to solve.

For children with dyslexia, this difficulty is even greater. Even when text is clearly written, rereading already requires extra effort. When handwriting is unclear, the cognitive load multiplies.

As a result, the child may skip rereading altogether, miss errors or missing words, and lose the possibility to verify whether the text truly reflects what they intended to say.

Writing loses one of its most important feedback loops.

Fine motor skills and spatial organisation

Handwriting relies heavily on fine motor skills, the ability to make small, precise movements with the fingers and hand.

When these skills are not sufficiently developed, pencil grip may be inefficient, pressure on the page inconsistent, letter formation unstable, and writing slow and tiring.

Difficulties with motor planning and coordination can also affect spatial organisation: staying on the line, spacing words, using margins, or organising steps in maths.

In these cases, the page itself becomes chaotic, not because the child’s thinking is disorganised, but because managing space adds another layer of effort.

Small adjustments, big differences

Over the years, I have worked with many children and teenagers with different handwriting and motor profiles. One recurring lesson is this:

Small, well-targeted adjustments can make a significant difference.

I remember a student in early secondary school who struggled in maths assessments, not because he didn’t understand the concepts, but because his handwriting made it difficult to follow the sequence of steps.

Once the layout began to support his writing, his reasoning became visible. His accuracy improved, and so did his confidence.

Progress did not come from “trying harder”, but from reducing unnecessary cognitive load.

A bridge towards supportive tools

Recognising these difficulties is not about lowering expectations or avoiding writing.
It is about rethinking how writing is supported, so that the act of writing no longer absorbs all available mental energy.

When the mechanical aspects of writing are scaffolded, children regain access to what matters most: thinking, organising, and communicating meaning.

Supportive tools are not shortcuts.
They are bridges, allowing ideas to travel from mind to page without being lost along the way.

So… what could actually help?

If writing is slow and effortful, the goal is not to reduce expectations.
The goal is to separate what we are assessing from what is still developing.
When the focus is on ideas, imagination, and expressive ability, writing needs to be supported differently.

In practice, this often means:
