Sensory Issues at Parliament Buildings

Many autistic people have difficulty processing everyday sensory information such as sounds, sights and smells. This is usually called having sensory integration difficulties, or sensory sensitivity. It can have a profound effect on a person's life.

Within Parliament Buildings there are numerous things going on during the course of the day which would have little effect on a person who does not have autism. However an autistic person could find them very stressful. Some examples (out of many) would be:

  • The Division Bells which sound to call Members to the Chamber to vote
  • Hand Dryers
  • Building Work to the Building such as Drilling
  • The Fire Alarm going off or being tested on a Friday morning at 9.30am
  • Flashing beacons in the bathrooms whenever the fire alarm goes off
  • The Smell of Paint if the Building is being decorated
  • The Smell of Cleaning Products
  • Shaking Hands with People
  • Large Crowds of People and Background Noise
  • Lighting
  • Food / Catering

Each autisitc person has individual sensitivities so no one person will have the same sensory issues.

If there are any obvious sensory issues occurring at the building such as noisy construction work or painting we will put this information on the homepage of the Assembly Autism web page. We also have a Quiet Room within parliament buildings which a person with autism can use if they need to. In the room we also have some sensory items, including ear defenders which can be borrowed while in the Assembly Building.

More detailed information on sensory issues can be read below.

How our senses work

Our central nervous system (brain) processes all the sensory information we receive and helps us to organise, prioritise and understand the information. We then respond through thoughts, feelings, motor responses (behaviour) or a combination of these.

We have receptors all over our bodies that pick up sensory information, or 'stimuli'. Our hands and feet contain the most receptors. Most of the time, we process sensory information automatically, without needing to think about it much.

People with sensory integration difficulties - including many autistic people - have difficulty processing everyday sensory information.

People who struggle to deal with all this information are likely to become stressed or anxious, and possibly feel physical pain. This can result in challenging behaviour.

Our seven senses

We have seven senses:

  • sight
  • sound
  • touch
  • taste
  • smell
  • balance ('vestibular')
  • body awareness ('proprioception').

Autistic people can be over- or under-sensitive in any or all of these areas. You may hear this referred to as being 'hypersensitive' or 'hyposensitive'.

Sensory sensitivities


Situated in the retina of the eye and activated by light, our sight helps us to define objects, people, colours, contrast and spatial boundaries. Autistic people may experience the following differences.

Hypo (under-sensitive)

  • Objects appear quite dark, or lose some of their features.
  • Central vision is blurred but peripheral vision quite sharp.
  • A central object is magnified but things on the periphery are blurred.
  • Poor depth perception – problems with throwing and catching; clumsiness.

Hyper (over-sensitive)

  • Distorted vision: objects and bright lights can appear to jump around.
  • Images may fragment.
  • Easier and more pleasurable to focus on a detail rather than the whole object.


This is the most commonly recognised form of sensory impairment. Hearing impairments can affect someone's ability to communicate and possibly also their balance. Autistic people may experience the following differences.


  • May only hear sounds in one ear, the other ear having only partial hearing or none at all.
  • May not acknowledge particular sounds.
  • Might enjoy crowded, noisy places or bang doors and objects.


  • Noise can be magnified and sounds become distorted and muddled.
  • Particularly sensitive to sound and can, for example hear conversations in the distance.
  • Inability to cut out sounds – notably background noise, which often leads to difficulties concentrating.


Touch is important for social development. It helps us to assess the environment we are in (is an object hot or cold?) and react accordingly. It also allows us to feel pain. Autistic people may experience the following differences.


  • Holds others tightly - needs to do so before there is a sensation of having applied any pressure.
  • Has a high pain threshold.
  • May self-harm.
  • Enjoys heavy objects (eg, weighted blankets) on top of them.


  • Touch can be painful and uncomfortable; people may not like to be touched and this can affect their relationships with others.
  • Dislikes having anything on hands or feet.
  • Difficulties brushing and washing hair because head is sensitive.
  • Only likes certain types of clothing or textures.


Chemical receptors in the tongue tell us about different tastes - sweet, sour, spicy and so on. Autistic people may experience the following differences.


  • Likes very spicy foods.
  • Eats everything - soil, grass, Play-dough. This is known as pica.


  • Finds some flavours and foods too strong and overpowering because of very sensitive taste buds. Has a restricted diet.
  • Certain textures cause discomfort; some children will only eat smooth foods like mashed potatoes or ice-cream.


Chemical receptors in the nose tell us about smells in our immediate environment. Smell is the first sense we rely upon. Autistic people may experience the following differences.


  • Some people have no sense of smell and fail to notice extreme odours (this can include their own body odour).
  • Some people may lick things to get a better sense of what they are.


  • Smells can be intense and overpowering. This can cause toileting problems.
  • Dislikes people with distinctive perfumes, shampoos, etc.

Balance (vestibular)

Situated in the inner ear, our vestibular system helps us maintain our balance and posture, and understand where and how fast our bodies are moving. Autistic people may experience the following differences.


  • A need to rock, swing or spin to get some sensory input.


  • Difficulties with activities like sport, where we need to control our movements.
  • Difficulties stopping quickly or during an activity.
  • Car sickness.
  • Difficulties with activities where the head is not upright or feet are off the ground.

Body awareness (proprioception)

Situated in the muscles and joints, our body awareness system tells us where our bodies are in space, and how different body parts are moving. Autistic people may experience the following differences.


  • Stands too close to others, because they cannot measure their proximity to other people and judge personal space.
  • Hard to navigate rooms and avoid obstructions.
  • May bump into people.


  • Difficulties with fine motor skills: manipulating small objects like buttons or shoe laces.
  • Moves whole body to look at something.


Synaesthesia is a rare condition which some autistic people experience. A sensory experience goes in through one system and out through another. So a person might hear a sound but experience it as a colour. In other words, they will 'hear' the colour blue.

Ways to help

Here are some ways you may be able to help a person with sensory sensitivity. Often, small changes to the environment can make a difference.

Three points to remember are:

  • BE AWARE: look at the environment to see if it is creating difficulties for autistic people. Can you change anything?
  • BE CREATIVE: think of some positive sensory experiences
  • BE PREPARED: tell autistic people about possible sensory stimuli they may experience in different environments.

Ways to help: sight

Hypo (under-sensitive)

  • Increase the use of visual supports.

Hyper (over-sensitive)

  • Reduce fluorescent lighting - use deep-coloured light bulbs instead.
  • Provide sunglasses.
  • Use blackout curtains.

Ways to help: sound


  • Use visual supports to back up verbal information.


  • Shut doors and windows to reduce external sounds.
  • Prepare a person before going to noisy or crowded places.
  • Provide ear plugs
  • Have a quiet room

Ways to help: touch


  • Use weighted blankets.


  • Warn a person if you are about to touch him or her; always approach him or her from the front.
  • Remember that a hug may be painful rather than comforting.
  • Gradually introduce different textures - have a box of materials available.
  • Allow a person to complete activities themselves so that they can do what is comfortable for them.

Ways to help: taste

Some autistic people are hyper- or hyposensitive to taste, and may limit themselves to bland foods or crave very strong-tasting food. You could advise someone of the catering and menus available.

Ways to help: smell


  • Use strong-smelling products as rewards and to distract people from inappropriate strong-smelling stimuli.


  • Use unscented detergents or shampoos, avoid wearing strong perfume, make the environment as fragrance-free as possible.

Ways to help: balance


  • Encourage activities that help to develop the vestibular system. For children this could include using rocking horses, swings, roundabouts and seesaws. For adults, try games like catching a ball or practise walking smoothly up steps or curbs.


  • Break down activities into small, more easily manageable steps; use visual cues such as a finish line.

Ways to help: body awareness


  • Position furniture around the edge of a room to make navigation easier.
  • Put coloured tape on the floor to indicate boundaries.
  • Use the 'arm's-length rule' to judge personal space. This means standing an arm's length away from other people.


  • Do 'fine motor' activities like lacing boards.
