Retained Primitive Reflexes: The Hidden Reason Kids Struggle to Focus in Class

If your child's school reports keep mentioning "difficulty concentrating," "easily distracted," or "struggles to sit still," it's worth knowing about a physical explanation that rarely gets mentioned in parent-teacher interviews: retained primitive reflexes.

What are primitive reflexes?

Primitive reflexes are automatic movement patterns babies are born with — things like the Moro (startle) reflex, the Asymmetrical Tonic Neck Reflex (ATNR), and the Tonic Labyrinthine Reflex (TLR). They exist to help a baby survive and move through the earliest stages of development: rolling, lifting the head, and eventually crawling and walking.

In typical development, these reflexes are gradually "integrated" — meaning the brain matures past needing them, and voluntary, controlled movement takes over. This integration usually happens naturally through tummy time, crawling, rolling, and general early movement play, generally by around age one.

What happens when a reflex isn't fully integrated?

When a primitive reflex hasn't fully integrated, it can keep firing involuntarily well past infancy — and because these reflexes are automatic, a child has no control over them. Depending on which reflex is involved, an unintegrated reflex can look remarkably similar to an attention or behaviour issue in the classroom, even though the root cause is physical.

How retained reflexes can mimic classroom inattention

A few common examples:

• Retained Moro reflex: can leave a child in a near-constant low-level state of alertness or overwhelm, making them appear anxious, easily startled, or emotionally reactive to normal classroom stimulation.
• Retained ATNR: can interfere with a child's ability to cross the midline of their body, which shows up as difficulty with handwriting, reading across a page, or coordinating both sides of the body — often mistaken for carelessness or lack of effort.
• Retained TLR: can affect balance and posture, meaning a child needs to expend extra effort just to sit upright at a desk, leaving less mental capacity available for actually listening or concentrating.
• Retained Spinal Galant reflex: can create restlessness or fidgeting specifically when a child's lower back is touched — including simply sitting back against a chair — which can look identical to an inability to sit still.

None of these are about a child choosing not to concentrate. Their nervous system is genuinely working overtime on something most of us stopped needing to think about before our first birthday.

Why this gets missed so often

Retained primitive reflexes aren't something that shows up on a standard hearing or vision test, and they're not always part of a general paediatric check-up. They sit in a gap between physical development and classroom behaviour — which means the behaviours they cause are frequently labelled as attention difficulties, defiance, or anxiety, without anyone considering the physical root.

The good news: reflex integration can be supported at home

Reflex integration isn't about a one-off appointment or a diagnosis. It's a gradual process supported by specific, repeatable movement patterns — done consistently, in short sessions, over weeks. This is exactly the kind of home-based work that doesn't require a clinic visit to start.

I'm Robyn Papworth, a vestibular specialist and Exercise Physiologist. I put together a full guide on this because so many parents were describing "inattentive" behaviours in their kids that, once we looked closer, were actually reflex-driven physical patterns — not a focus problem at all.
