Sensory Processing Differences
Types of Sensory Processing Differences
Sensory Processing Differences are described as patterns, not severity levels — chiefly sensory modulation differences (over-responsive, under-responsive, sensory seeking), sensory-based motor differences (postural and motor-planning), and sensory discrimination differences. Patterns often overlap, and a clinician-administered assessment identifies which applies.
Sensory processing isn't one thing that's simply present or absent — it shows up as distinct patterns, and knowing the pattern is what makes support precise.
In short
Sensory Processing Differences are usually grouped into a few recognised patterns rather than "levels" or severities. The most widely used framework describes three broad types: sensory modulation differences (how strongly a child responds to input), sensory-based motor differences (how the body uses sensory information to move and plan), and sensory discrimination differences (how precisely a child tells sensations apart). Each pattern can be mild and barely noticeable, or significant enough to affect everyday play, learning and self-care.The patterns, explained simply
1. Sensory modulation differences — the volume control of the sensory system.- Over-responsive (sensory avoiding): sounds, textures, lights or touch feel too intense; the child may cover ears, dislike certain clothing, or be upset by messy play.
- Under-responsive: the child seems not to notice sensations — slow to react to name, pain, or mess.
- Sensory seeking: the child craves more input — spinning, crashing, mouthing, constant movement.
2. Sensory-based motor differences — using sensation to plan and move.
- Postural differences: low muscle tone, slumping, tiring quickly, trouble holding a position.
- Dyspraxia (motor planning): difficulty figuring out and sequencing new movements, looking clumsy or hesitant with new tasks.
3. Sensory discrimination differences — telling sensations apart.
- Trouble judging which sensation it is, where on the body, or how much — for example, gripping a pencil too hard, or struggling to find an object by touch.
These patterns often overlap, and a child can show one strongly and another mildly. They describe how a child experiences the world — not a measure of intelligence or potential.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online list or an app, because the same behaviour can have very different causes. A clinician-administered assessment looks at the whole picture and identifies which pattern is at play.

WHO ICD-11 and the ICF framework on functioning; the American Academy of Pediatrics (HealthyChildren.org) and CDC developmental guidance; Indian Academy of Pediatrics. These describe sensory differences within a broader developmental and functional view rather than as fixed severity grades.Next step — Curious which pattern fits your child?

What to watch
Watch whether a sensory reaction is consistent and across settings — covering ears at every loud place, avoiding many textures, constant crashing and spinning, or seeming not to notice mess or name-calling. Patterns that affect play, dressing, eating or learning are worth a developmental check.
Try this at home
Notice your child's pattern, not just the moment: keep a simple week-long note of what they avoid, crave or miss. This 'sensory diary' helps a clinician see the pattern far faster than a single visit can.

Frequently asked
Are there official 'levels' of Sensory Processing Differences?
Not in the way severity levels work for some conditions. Sensory differences are described as patterns — modulation, motor and discrimination types — and each can range from mild to significant. A clinician describes how it affects daily life rather than assigning a fixed grade.
Can a child have more than one type at once?
Yes, very commonly. A child might be over-responsive to sound yet seek out movement, or have a motor-planning difficulty alongside a discrimination difference. Overlap is normal, which is why a structured assessment is more useful than a single label.
Is sensory seeking the same as hyperactivity?
Not necessarily. Sensory seeking is the brain craving more input — spinning, crashing, mouthing — to feel regulated, and it can look like restlessness. Only a qualified clinician can tell whether it reflects a sensory pattern, attention differences, or both.
