Understanding the 8 Sensory Systems: A Neuroaffirming Guide for Families and Educators

When we think of the senses, most of us picture the “big five”: sight, sound, smell, taste, and touch. But did you know our bodies actually rely on eight sensory systems to help us understand, connect with, and feel safe in the world around us?

For neurodivergent children and adults, these sensory systems may work in wonderfully unique ways. Some may seek out movement or noise, others might avoid certain textures or sounds. None of these experiences are “wrong” or “bad”, they are simply differences in how the brain processes sensory information.

As occupational therapists, we celebrate this diversity. We take a strengths-based, neuroaffirming approach, which means we don’t aim to “fix” or “normalise” sensory responses, but instead empower individuals to understand their needs, advocate for them, and engage in meaningful activities in ways that work for them.

Let’s take a closer look at the 8 sensory systems, what they do, and how they might show up in everyday life.

1. Visual (Sight)
   This is how we interpret what we see: light, colour, shapes, movement, and distance.
   A child might…
   Seek out bright, spinning objects (sensory seeking)
   Feel overwhelmed by bright lights or busy visuals (sensory avoiding)
   
   Neuroaffirming support: Offer choices for lighting (e.g., natural light, lamps) and visuals (e.g., minimal decorations, visual breaks).
2. Auditory (Hearing)
   This system helps us process sounds like voices, music, background noise, and even silence.
   A child might…
   Crave loud, rhythmic music or make loud vocalisations
   Cover their ears or become distressed in noisy places
   
   Neuroaffirming support: Use noise-cancelling headphones, soft music, or prepare children in advance for noisy environments.
3. Olfactory (Smell)
   This is our sense of smell-closely connected to memory, emotion, and even appetite.
   A child might…
   Seek out strong smells (e.g., candles, food, scented markers)
   Gag or feel unwell around certain odours
   
   Neuroaffirming support: Respect scent sensitivities and support choice in scented or unscented environments.
4. Gustatory (Taste)
   This system helps us detect flavours, textures, and temperatures in food and drinks.
   A child might…
   Prefer intense flavours (e.g., spicy, sour) or crunchy foods
   Be cautious or avoidant of mixed textures or new foods
   
   Neuroaffirming support: Offer safe, preferred foods while gently supporting food exploration at the child’s pace.
5. Tactile (Touch)
   This involves how we experience touch-pressure, temperature, vibration, pain, and texture.
   A child might…
   Love messy play and touching everything
   Avoid tags, seams, or unexpected touch
   
   Neuroaffirming support: Let children choose clothing that feels good, and respect consent when it comes to touch (even in play).
6. Vestibular (Balance & Movement)
   This sense tells us where our body is in space in relation to gravity. It helps us balance, move smoothly, and feel grounded.
   A child might…
   Love spinning, swinging, or jumping
   Feel dizzy or disoriented with fast movement
   
   Neuroaffirming support: Provide movement breaks, rocking chairs, swings, or calm, grounded movement experiences.
7. Proprioception (Body Awareness)
   This system tells us where our body parts are and how much force to use.
   A child might…
   Seek deep pressure (e.g., hugs, crashing, jumping)
   Appear clumsy or use too much or too little force

   Neuroaffirming support: Offer heavy work activities (e.g., pushing, pulling, carrying) and movement games that provide feedback.

8. Interoception (Internal Body Awareness)
   This lesser-known system helps us understand internal sensations like hunger, thirst, needing the toilet, pain, and emotions.
   A child might…
   Struggle to recognise when they’re hungry, tired, or need a break
   Find it hard to connect physical feelings with emotions

   Neuroaffirming support: Use visual supports, body maps, or check-ins to build awareness and language around internal cues.

Final Thoughts:
Everyone has a unique sensory profile-there is no “right” or “wrong” way to experience the world. Understanding the 8 sensory systems helps us create environments where neurodivergent children feel safe, empowered, and able to thrive.

As OTs, parents, and educators, our goal is not to change who a child is, but to listen, support, and adapt so they can participate fully in life on their own terms.
