Senses

Some children’s brains process information from the senses differently. 

On this page

Sensory processing — over and under sensitivity

Children can be over-sensitive, under-sensitive to sensory input, or both.

A child who is over-sensitive may show signs such as:

  • being upset by sounds other children do not notice
  • disliking certain fabrics or clothing textures
  • finding bright lights uncomfortable
  • reacting strongly to smells

A child who is under-sensitive may:

  • seek out movement, spinning or crashing
  • look for strong tastes or textures
  • not react to pain or heat in the usual way

 

Sensory-seeking and sensory-avoiding

Some children actively look for more sensory input. Others move away from it. Both can happen in the same child.

Interoception — internal body sense

Interoception is the sense that tells us what is happening inside our bodies.

A child with differences in interoception may show signs such as:

  • not noticing when they are hungry or thirsty
  • not showing the usual signs of pain
  • not recognising when they need the toilet
  • finding it hard to tell others when they feel unwell

Pain and communication of pain

Some children with sensory differences may not respond to pain in the usual way. It can be hard to know if they have been hurt or feel unwell.

Proprioception and body awareness

Proprioception tells us where our body is in space.

A child with differences in proprioception may:

  • find it hard to judge distances
  • use too much or too little pressure when writing
  • have difficulty with balance and coordination

Example — Clive:

Clive is sensory seeking, he has an area at home and school with a trampoline and swing. He likes tactile objects, spinning objects and going upside down. He does not feel pain in the same way, which their parents make sure the doctor and health professionals know about. 

Note: Our examples are made up to show common experiences and are not real children.

What is it like to sense differently?

For some children with neurodevelopmental differences, sensory processing is different from typical peers. Some differences that children may experience are:

  • finding some everyday experiences noisy and distressing, such as hand dryers in public bathrooms
  • not liking artificial lights such as in supermarkets
  • seeking sensory input such as the trampoline or swing
  • avoiding food with certain textures or smells
  • not able to focus well at school or home if the sensory environment is overwhelming

What families say

9 out of 10 families in our survey told us sensory differences were important issues for their children with neurodevelopmental needs (322 out of 360 or 89%).

Growing Different Parent Survey 2024 – notes and limitations

394 families of neurodivergent children took part in our online survey. Most children were autistic (about 8 in 10). People chose to take part, so the figures show their experiences, not all children. We did not compare them with any other group, so they can’t show how common something is or what causes it. Some questions had more responses than others.
