Understanding Sensory Processing: The 8 Senses

Most people learn about 5 senses in school. Occupational therapists work with 8 sensory systems, all of which can be affected in autism.

The Classic 5 Senses

  • Visual (Sight)

    Sensitivity to brightness, flickering lights, busy visual environments, or certain colours

  • Auditory (Sound)

    Difficulty filtering background noise, distress from sudden or high-pitched sounds

  • Tactile (Touch)

    Avoidance of light touch or certain textures on skin or in food

  • Olfactory (Smell)

    Heightened detection of odours that others may not notice; can trigger nausea or panic

  • Gustatory (Taste)

    Extreme selectivity based on taste, texture, or temperature of food

The 3 Hidden Senses

  • Vestibular (Movement & Balance)

    Located in the inner ear. Controls balance, spatial awareness, and tolerance for movement. Dysfunction leads to fear of swings or constant spinning and rocking.

  • Proprioceptive (Body Position)

    Feedback from muscles and joints about where the body is in space. When dysregulated, children crash into things, use too much force, or seek deep pressure like tight hugs or weighted blankets.

  • Interoceptive (Internal Body Signals)

    Awareness of hunger, thirst, pain, heart rate, and the need to use the bathroom. Poor interoception is linked to emotional regulation difficulties and toileting challenges.

The Four Sensory Profiles (Dunn's Model)

Winnie Dunn's Sensory Profile framework, the gold standard used by Ontario OTs, identifies four patterns based on neurological threshold and behavioural response.

Sensory Seeking

Low Registration / Active Response

The nervous system needs more input than average to register sensations. These individuals are sensory cravers, constantly moving, touching everything, seeking intense input.

Common signs:

  • Crashing into furniture or people
  • Chewing on non-food objects
  • Spinning or rocking for long periods
  • Loves rough-and-tumble play
  • Talks loudly or constantly

Sensory Avoiding

High Threshold / Active Response

The nervous system is over-responsive and works hard to limit input. These individuals have strong reactions to sensations others barely notice.

Common signs:

  • Distress from light touch or clothing tags
  • Covers ears in moderate noise
  • Gags at food textures
  • Avoids messy play
  • Overwhelmed in busy spaces

Sensory Sensitivity

Low Threshold / Passive Response

Notices everything, high registration, but responds with distraction or distress rather than active avoidance. Often described as easily bothered or irritable.

Common signs:

  • Easily distracted by background noise
  • Complains about smells others ignore
  • Difficulty concentrating in busy classrooms
  • Startles easily
  • Irritable in new environments

Low Registration

High Threshold / Passive Response

Slow to notice sensory information. May appear unaware of pain, mess, or temperature. Often perceived as in their own world or having a high pain tolerance.

Common signs:

  • Does not notice when hurt
  • Unaware of body odour or messy face
  • Slow to respond to name
  • May not feel extremes of temperature
  • Appears disconnected
Core Strategy

What is a Sensory Diet?

A sensory diet is a personalized, OT-designed schedule of sensory activities distributed throughout the day to keep the nervous system in an optimal state for learning, social engagement, and daily function. The term was coined by Patricia Wilbarger, OTR, and is the primary OT intervention for sensory processing differences.

Despite the name, it has nothing to do with food. Think of it as a daily exercise plan for the nervous system, providing the right type and amount of sensory input at the right times.

1

Sensory Assessment

An OT conducts a formal evaluation using standardized tools (Sensory Profile 2, Sensory Processing Measure) plus observation and parent report to map your child's profile across all 8 senses.

2

Identifying Sensory Needs

The OT identifies which sensory systems are over-responsive, under-responsive, or dysregulated, and when during the day regulation is most challenging.

3

Designing the Diet

Activities are selected and timed to match your child's schedule. A school-aged child might have a proprioceptive activity before class, a movement break at recess, and deep pressure before homework.

4

Implementation

The diet is carried out by parents, educational staff, and caregivers. The OT trains everyone and adjusts the plan as your child's needs evolve.

5

Monitoring and Adjustment

Regular OT check-ins (typically monthly or quarterly) review what's working, adjust activities, and ensure the diet keeps pace with development.

Sensory Strategies by Environment

Sensory needs vary by context. Here are evidence-supported strategies for the three settings where autistic children spend most of their time.

Home

  • Designate a low-stimulation calm space (tent, corner with dim light)
  • Use weighted blankets at approximately 10% of body weight
  • Offer a movement corner with mini-trampoline or balance board
  • Use dimmable lighting and blackout curtains in bedrooms
  • Noise-cancelling headphones during high-stimulation activities
  • Chewy jewellery or chew tools for oral sensory seekers
  • Consistent, predictable sensory diet schedule posted visually

School

  • Request sensory accommodations in IEP (movement breaks, seating)
  • Wobble cushion or therapy ball seating for vestibular input
  • Preferential seating away from hallway noise or classroom door
  • Scheduled movement breaks (hallway walk, jumping jacks)
  • Fidget tools approved for desk use during instruction
  • Headphones for independent work time
  • Early warning system with teacher for sensory overload

Community

  • Carry a portable sensory kit at all times (headphones, sunglasses, fidgets)
  • Time outings for low-traffic periods (early morning, weekdays)
  • Scout venues in advance using photos or virtual tours
  • Identify quiet exits and calm spaces before entering
  • Give advance notice of the outing plan and expected duration
  • Use noise-reducing ear defenders in loud spaces
  • Prepare a quick exit plan and communicate it to your child

Accessing Occupational Therapy in Ontario

Occupational therapists registered with the College of Occupational Therapists of Ontario (COTO) are the primary professionals for sensory assessment and intervention. Ontario families access OT services through the pathways below.

Pathways to OT Access

  • School Board OT (Free)

    All Ontario school boards employ itinerant OTs. Request a referral through your child's principal. School OTs can implement sensory accommodations in the IEP and model strategies for teachers.

  • OAP Core Clinical Services

    OT is covered under OAP funding. The wait for Core Clinical Services is currently measured in years. Interim one-time funding (an amount set by age band) can be used in the interim.

  • Preschool Speech and Language Program

    The PSP program includes OT services for children ages 0–6 at no cost. Contact your local children's treatment centre.

  • Private OT (Out of Pocket)

    Registered OTs in Ontario commonly charge hourly rates in the low-to-mid hundreds of dollars (rates vary by region and provider). Many accept OAP funding, extended health benefits, or SSAH funding.

Questions to Ask Your OT

  • What standardized sensory assessment tool will you use?
  • Can you explain my child's sensory profile across all 8 systems?
  • Will you create a written sensory diet with a daily schedule?
  • Can you train our school team to implement the strategies?
  • How often will we have follow-up sessions and how will we track progress?
  • Do you accept OAP funding or SSAH? Can you direct-bill?

Home Setup

Building a Home Sensory Space

A dedicated sensory space at home gives your child a regulated, predictable environment where they can self-regulate. It does not require significant space or expense, a corner of a bedroom or living room works well.

1

Choose the Location

A quiet corner of a bedroom or a closet with the door removed work well. Avoid high-traffic areas. The space should feel safe and private.

2

Control Light and Sound

Use string lights or a dimmable lamp instead of overhead lighting. A white noise machine or speaker with calming music reduces auditory distractions.

3

Add Deep Pressure Options

A weighted blanket at approximately 10% of body weight, a body sock, or a compression vest provides proprioceptive input. A cozy tent or canopy can give a sense of enclosure.

4

Include Movement Opportunities

A small trampoline, balance board, or exercise ball can provide vestibular input. Even a swivel stool on a designated spinning spot on the floor counts.

5

Provide Tactile and Oral Tools

Sensory bins (rice, kinetic sand), fidget tools, and chew tools address tactile and oral needs. Keep items organized so the space stays calming.

How many children are on the Ontario autism waitlist?

Verified

Latest FOI data shows 91,974 children are registered in the Ontario Autism Program (May 2026), while 22.5% have active funding agreements. [FOI] An active funding agreement does not mean a child is receiving services; it is an administrative status distinct from service delivery. The Ontario Autism Coalition reported in July 2026 that some families in its community had waited more than five years. That report is not a province-wide average. Last verified: 2026-08-10
