Here’s a site-ready intro for the top of the Perceptual Worlds page on Stimpunks.org:
Perceptual Worlds
We don’t all experience the world in the same way — and that’s not a flaw. It’s a simple fact of human variation. A room, a conversation, a classroom, or a website isn’t just “out there.” It is lived through bodies and nervous systems. How we see, hear, move, and sense our internal states shapes what feels safe, what feels painful, and what feels possible.
This page is about perceptual worlds — the ways different minds and bodies make meaning from sensory input and internal signals. When environments assume one way of experiencing, they erase others. That erasure causes real harm: overload, shutdown, avoidance, exhaustion, and exclusion. Understanding perceptual worlds helps us see that access isn’t a checklist or an add-on. Access is design — infrastructure that makes spaces livable for many kinds of perception.
If you want design that works for real minds instead of trying to “fix” people, start here: notice how environment and perception shape each other. Then you can begin to build spaces that reduce harm and invite participation.
Understanding the sensing and perceptual world of autistic people is central to understanding autism.
Everyone has eight sensing systems: the first five being the familiar sight, hearing, smell, touch and taste. These five give us information about the world outside our bodies. Three internal sensing systems give us information from inside our bodies – our vestibular system (coordinating movement with balance), proprioception (awareness of position and movement of the body) and interoception (knowing our internal state including feelings, temperature, pain, hunger and thirst). Although not all the external senses are equally affected by the physical environment, we consider them all – as they collectively add to the ‘sensory load’ that many autistic people often experience. Any sensory input needs to be processed and can reduce the capacity to manage and process other things.
As many autistic people process one thing at a time, sensory stimulation can stack up. As the brain’s highways become congested, there are repercussions throughout the entire neural network. This can lead to headaches, nausea and the fight and flight response, this is what causes many meltdowns and shutdowns.

Perceptual Worlds
Perceptual worlds are not abstract ideas — they are the real ways our bodies and nervous systems experience the environment. How we see, hear, move, feel, and orient ourselves is shaped by both our internal senses and the world around us. When environments are built for one narrow sensory mode, they erase lived experience and punish difference. This section introduces perceptual worlds so you can see access not as extra work, but as design for actual human experience.
Though autistic people live in the same physical world and deal with the same ‘raw material’, their perceptual world turns out to be strikingly different from that of non-autistic people.
Differences in perception lead to a different perceptual world that is inevitably interpreted differently. We have to be aware of these differences and help autistic individuals cope with painful sensitivities and develop their strengths (‘perceptual superabilities’) that are often unnoticed or ignored by non-autistic people.

The inability to filter foreground and background information can account for both strengths and weaknesses of autistic perception. On the one hand, autistic individuals seem to perceive more accurate information and a larger amount of it. On the other hand, this amount of unselected information cannot be processed simultaneously, and may lead to information overload. As Donna Williams describes it, autistic people seem to have no ‘sieves’ in their brains to select the information that is worth being attended to. This results in a paradoxical phenomenon: sensory information is received in infinite detail and holistically at the same time. This can be described as ‘gestalt perception’, that is, perception of the whole scene as a single entity with all the details perceived (not processed!) simultaneously. They may be aware of the information others miss, but the processing of ‘holistic situations’ can be overwhelming.

Sensory Overload by Alexis Quinn
If we are serious about enabling thriving in autistic lives, we must be serious about the sensory needs of autistic people, in every setting. The benefits of this extend well beyond the autistic communities; what helps autistic people will often help everyone else as well.

“Patterns are a real problem for me. I get absorbed by them – they take all my focus and it’s really distressing. When I’m overloaded sound and visuals can become too intense. My ability to manage fluctuates depending on how overloaded I am. When I’m overloaded, I can’t manage visual clutter, things on mantelpieces and walls, open fires, pattered carpets or clocks ticking. These are all things that would seem fine on a good day but become too much.”
“I have massive sensory sensitivity. Especially to light and sound. My sensitivity fluctuates depending on how overloaded I am. If I’m not overloaded, then I can tolerate a lot more.”
Supporting Autistic Flourishing at Home and Beyond – Alexis Quinn artwork – NDTi
I’m telling my story on behalf of the thousands of people with autism and / or learning disabilities who are inappropriately detained in hospitals…
I don’t respond well in a hospital, so I was stimming and pacing.
Stimming feels good to me and counteracted the busy, chaotic sensory environment of the hospital.
Overloaded that day, I desperately needed my walk. The staff, as usual, were very busy. I didn’t want to disturb them, but I had to have someone let me out. There were three doors between me and the outside world.

The divergent ways in which we process the world around us can also leave us fatigued and sapped of energy, as autistic people have “higher perceptual capacity” than our neurotypical counterparts, meaning that we process greater volumes of information from our environment. Autistic people commonly use the concept of ‘spoon theory‘ to conceptualize this experience of having limited energy resources. Initially theorized in the context of chronic illness, spoon theory can be explained as every task and activity (enjoyable or otherwise) requiring a certain number of ‘spoons’. Most people start their day with such an abundance of spoons that they can do whatever they choose, and rarely run low. We autistic folk start with a limited number of spoons, and when those spoons run dangerously low, we need to step back, rest, engage in self-care, and wait for our spoons to replenish.

Sensory Trauma
Sensory trauma happens when the world is repeatedly too much — too loud, too bright, too fast, too unpredictable — and the nervous system has no way to escape or recover. It’s what occurs when sensory overwhelm isn’t a rare moment, but a chronic condition of daily life. For many neurodivergent and disabled people, trauma isn’t only about events. It’s about environments that constantly signal threat through sound, light, touch, crowding, and demand.
Sensory trauma is often invisible to outsiders because it looks like “behavior” instead of injury: shutdown, avoidance, agitation, dissociation, or burnout. This section names sensory trauma as real harm, not sensitivity or preference, and focuses on what actually helps: sensory safety, predictable spaces, regulation supports, and access infrastructure that stops punishing difference.
Sensory Trauma is the name Autism Wellbeing has given to a phenomenon that autistic people have long been describing in our words and actions. The events we experience as physically or emotionally harmful or life threatening may not necessarily be the extreme events typically associated with trauma. Sensory Trauma may arise from everyday activities such as taking a shower or going shopping. It can occur frequently and lead to us spending our lives in a state of hypervigilance. We respond to sensory information in a way that is totally proportionate to our genuine, lived experience. However, our responses may be mislabelled or misunderstood.
The impact of Sensory Trauma is significant. Infants may miss out on regulating, growth-promoting parental input. Toxic stress may modify areas of the brain involved in learning and memory and increase our vulnerability to a range of physical and mental health experiences with poorer outcomes.
How sensory trauma affects how we grow develop and learn
The long-term effects of misunderstanding or mislabeling sensory trauma can be catastrophic.
How sensory trauma affects how we grow develop and learn
The interconnectedness between sensory input, emotions, energy level, ongoing task and how you manage everything you have to do alongside coping with sometimes overwhelming sensory input is an experience that many autistic people are familiar with. Understanding just how much the sensory world can impact how anxious you feel, how well you can communicate, how able to do a food shop or even just enter a space is an important piece of understanding to build up. Without this understanding, from the perspective of autistic people, many may not understand how all-consuming the sensory environment can be for some and for others it is a way of being able to interact that releases anxiety and tension. Interacting with the sensory world through sensory seeking behaviours is strongly associated with stimming (self-stimulatory behaviour that helps self-regulation) which is often a really positive (as long as no one is getting hurt) way of expression that can encompass happiness, anxiety, distress and so much more.
Autistic sensory experiences, in our own words — Sarah O’Brien
In considering autistic sensory experience, we are thinking about autistic lives, the day to day experience of living as an autistic person. Given its implication in the ordinary acts of everyday life, it is difficult to avoid the conclusion that, for many autistic people, sensory trauma has been there all along, hiding in plain sight.

What I understand autism to be – Spectrumy
Autism + environment = outcome.
When autistic people are placed in spaces that punish sensory reality, demand constant compliance, and treat difference as deficit, the result is distress, shutdown, burnout, and exclusion. When autistic people are supported with safety, access, autonomy, and humane design, the result is regulation, learning, connection, and thriving.
This section is a simple reframe: autism plus environment equals outcome. The question is not “What’s wrong with the autistic person?” The question is “What conditions are we creating?” Outcomes are built — and we can build better ones.

Making Spaces Safer: Bodymind Affirmation and Access Intimacy
The reality is that marginalized people experience discrimination in public spaces. As they move through their lives and through various spaces, they cannot predict if they will be treated with respect, let alone if they will be safe. When they attend a show or event at your space, they should be able to know what to expect, or at least what you intend to have happen—and not happen—within your walls. So, how can you let them know? You can’t just open the door; you have to put out a welcome mat.
