There is growing discussion about whether Ayres Sensory Integration (ASI) is truly neuroaffirming. Some argue that it is not, often because they have seen sensory strategies used in rigid or compliance-focused ways. However, others see ASI as deeply consistent with neuroaffirming values when practised as Jean Ayres intended.
This rhetoric we hear repeatedly is damaging, comes from a place of not knowing, but can mean people may dismiss the opportunities for support and self-understanding that Ayres’ theory of sensory integration and practice offers to people across the life span. When for some this is life-saving and quality of life restoring, this rhetoric is harmful – “do no harm”.
In this post, I want to explore why sensory integration can be understood as neuroaffirming, and why the way we frame and deliver it makes all the difference.
Respect and participation at the heart
Jean Ayres’ original work was never about normalising behaviour. It was about helping people access everyday life more fully. At its core, ASI is person-led: the therapist creates a safe and motivating space where the individual chooses, explores, and experiments with sensory input. This freedom to act on intrinsic motivation aligns strongly with the values of neuroaffirming practice.
Supporting the nervous system, not fixing the person
A neuroaffirming stance accepts that differences in sensory integration and processing are part of human diversity. ASI does not aim to erase those differences. Instead, it helps us understand them and provide what Ayres called the just-right challenge. In this way, the nervous system can develop and mature, adapt, regulate, and thrive, supporting participation in meaningful occupations.
Co-production built in
As taught and practised by ASI Wise and other organisations worldwide, contemporary sensory integration uses tools such as Sensory Ladders and Sensory Spiders alongside collaborative goal setting with people of any age. These approaches place the individual’s voice at the centre. Co-production is not an optional extra; it is integral to the process. This makes practice affirming, honouring lived experience rather than imposing outside standards.
Emotional regulation and safety
A key principle of neuroaffirming practice is the importance of nervous system safety and regulation. Sensory integration fits naturally here. Proprioceptive input, vestibular experiences, and tactile play are not used to change who someone is, but to help them feel grounded, calm, and able to participate. This is both practical and affirming.
The difference lies in how it is applied
Critics often respond to sensory approaches used in behaviourist or compliance-focused ways, which do not reflect fidelity-based SI. When sensory integration is practised with its full theoretical grounding, it is about curiosity, respect, and empowerment. Delivered with integrity, it is entirely consistent with neuroaffirming values.
Holding the reality in practice
A question that often arises is this: If neuroaffirming practice is about moving away from comparison to the norm, how do we reconcile that with the fact that most assessments rely on these comparisons?
The truth is that access to resources often depends on demonstrating need through measured differences. Many people would struggle to secure the support they deserve without those comparisons. At the same time, knowing whether your sensory profile is similar to or different from others can bring insight and self-understanding. It helps explain why certain environments or experiences may feel particularly difficult.
We also need to consider terminology. Words like “hyperreactivity” and “hyporesponsivity” describe states of the nervous system rather than fixed traits. Hyporesponsivity might occur due to medication, hormonal changes, or other factors, while hyperreactivity reflects heightened nervous system activation. Used carefully and alongside co-produced language, these terms can support understanding rather than judgement.
So, in practice, we have to accept both realities: the necessity of measurement for access and advocacy and the importance of using language that affirms and respects individual experience.
Use of Terms:
1. Recognise the value of physiological terms
Words like hyperresponsivity and hyporesponsivity can describe what is happening in the nervous system. For example, hyperresponsivity means the nervous system is firing at a higher level of reactivity; hyporesponsivity may reflect lower thresholds or slower responses. When used in this way, they are neutral descriptors, not judgements.
2. Acknowledge the lived experience of language
For many people, hyper and hypo don’t feel neutral at all. They are often heard as “too much” or “not enough,” feeding into stigma and the expectation that someone should change to fit a majority pattern. So even if physiologically accurate, these words can land as deficit language.
3. Balance through context and co-created language
One way forward is to keep the physiological terms in professional or clinical reasoning, but not assume they are the best fit for self-description. With clients or students, you can use co-created words or metaphors — “high signal,” “slow to warm,” “fast track,” “deep ocean,” or whatever makes sense to the person. This allows ownership of language without diminishing scientific clarity.
4. Shift from comparison to the majority toward individual needs
Rather than saying “this person is hypo compared to most people,” frame it as: “this person’s nervous system takes in less input before it responds,” or “this person’s body benefits from stronger input to feel safe and engaged.” This centres the person’s experience, not the majority’s.
5. Emphasise support, not correction
Language can always be framed in relation to what supports help. Instead of:
- “She is hyporesponsive to touch” to “She feels safer and more grounded with stronger tactile input.”
- “He is hyperresponsive to sound” to “He needs environments where sound can be reduced or controlled so he can focus.”
In conclusion
Sensory integration is neuroaffirming when it is framed and delivered in accordance with its original purpose and philosophy. It is about coproduction, respect for neurodiversity, and participation in everyday life. It is not about fixing or correcting but about supporting people’s feelings of safety and capability in their own bodies and environments.
