Topic 3: Sensory

Learning Goal

Understand that sensory differences in persons with autism can shape life’s challenges, behaviour and emotional regulation.

Key Learning Points

For some people with autism, everyday environments can feel like too much. Lights, sounds, movement, and touch may feel much more intense.

This is not a preference. This is also not something they can ignore or “switch off”.

It is how the brain processes sensory information.

Understanding Sensory Differences

People with autism may experience sensory information differently from others. For some, sights, sounds, or touch can feel much more intense and overwhelming. For others, the opposite may happen. Sensations may feel muted or harder to notice.

When this happens, a person may seek stronger input to help their body feel more aware and grounded. This is why some individuals may jump, spin, press against surfaces, or move in ways that seem unusual to others.

These behaviours are not meant to disturb others. They are often ways of helping the body regulate and make sense of the environment.

2. The Sensory Spectrum

Over-Sensitive

Some people experience sensory input very intensely.

Examples:

  • fluorescent lights feel painfully bright
  • overlapping sounds are hard to filter
  • clothing seams or tags feel irritating all day

When this happens, the world can feel overwhelming.

Under-Sensitive

Some people experience too little sensory input. They may have difficulty sensing where their body is in space.

Examples:

  • slamming doors without realising their strength
  • sitting or standing in unusual positions
  • seeking strong movement like jumping or spinning

These behaviours help the body feel more aware and grounded.

Additional Point:

Sometimes, we may witness a meltdown. What might look like “acting out” is often a total loss of control due to being overwhelmed by the environment. The individual isn’t being “fussy”; they cannot ‘just stop it’and it is not a temper tantrum. What they need is a little more understanding and patience from you, for their body and nervous system to return to a state of regulation.

3. The Compass in the Storm

When the sensory world feels confusing or overwhelming, some people with autism use repetitive movements or sounds to help their body calm down and stay focused. 

These self-stimulating or what we see as repetitive behaviors can serve different purposes.

A Perspective from someone with autism

What’s the reason you jump?

When I’m jumping it’s as if my feelings are going upward to the sky. Really, my urge to be swallowed up by the sky is enough to make my heart quiver. When I’m jumping, I can feel my body parts really well, too–my bounding legs and my clapping hands–and that makes me feel so, so good.”

― Naoki Higashida, The Reason I Jump: the Inner Voice of a Boy with Autism
