Sensory-Processing Informed Autism Practice for Child-Centred Therapists

This synthesis paper was recently published in the journal Research in Neurodiversity. It’s written by a team of nine professionals including occupational therapists, speech-language pathologists, behavioral health therapists, developmental psychologists, counsellors, and play therapists. More than half of them are autistic themselves.

The paper’s main goal is to teach child-centered therapists how to adapt their practice to better fit the sensory and communication needs of autistic children, without giving up the core of what makes their approach work.

Child-centered therapists are therapists who work one-on-one with kids in a relationship-focused, non-directive way. That includes play therapists, music therapists, art therapists, drama therapists, dance and movement therapists, somatic therapists, non-directive counselors, and child-centered OTs and SLPs. The core idea of child-centered therapy is that the therapist follows the child’s lead with empathy and acceptance, rather than directing what the child does.

The authors argue that most therapy training does not adequately prepare therapists for the sensory and communication needs of autistic children.

They’re responding to a real problem here. Meta-analyses have found that child-centered therapy training programs have not done a good job adapting to autistic kids’ sensory and communication needs. So therapists trained in these modalities often run into walls when working with autistic clients, and they default back to neurotypical assumptions.

Key Concepts

To follow the rest of the paper, a few foundational ideas need to be in place. The authors scaffold these carefully.

The eight senses

Most people learn about five senses in school. The full picture is eight. The five external senses are sight, sound, touch, taste, and smell. The three internal senses are vestibular (balance and head position), proprioception (where your body is in space and how it is moving), and interoception (the sense of what is happening inside your body, like hunger, needing the toilet, your heart racing, feeling cold).

Sensory processing differences in autism

Over 90% of autistic people experience sensory processing differences. These can show up as over-responsivity (sensations register more intensely), under-responsivity (sensations register more quietly), sensory craving, sensory discrimination problems, postural difficulties, or dyspraxia. Most autistic people experience more than one of these, sometimes contradicting each other.

Chronic dysregulation

For most autistic people, the body’s stress system is in a state of dysregulation as a baseline, not just when something stressful happens. That means many autistic kids walk into therapy already in fight, flight, freeze, or shutdown mode before anything has even started. This connects to higher rates of anxiety, depression, chronic pain, and IBS in the autistic population.

Interoception is central

When the interoceptive sense is unclear or jumbled, a child cannot easily tell when they are hungry, tired, overwhelmed, or about to melt down. That makes self-regulation extremely hard, because you cannot regulate something you cannot feel. This is one of the most important threads in the paper.

The double empathy problem

This concept by Damian Milton flips the older idea that autistic people have communication deficits. The double empathy problem says communication breakdowns between autistic and non-autistic people are bidirectional. Autistic kids miss some non-autistic communication cues, and non-autistic adults miss autistic kids’ cues just as often. The mismatch is shared, not one-sided.

Implicit biases non-autistic therapists tend to bring

The authors name these clearly. Non-autistic therapists tend to: assume the child experiences the sensory environment the way they do, assume the child understands how the therapist communicates emotions and intentions through voice and body, and assume the child has a coherent, integrated internal experience of bodily sensations and emotions.

All three assumptions can be wrong for autistic kids.

What They Did

The authors did extensive literature searches, drew on existing tested clinical models (DIRFloortime, PACT, SCERTS, Rhythmic Relating, autism-specialized Child-Centered Play Therapy, Kelly Mahler’s Interoception Curriculum), and added their own clinical experience and autistic lived experience. Three of the autistic authors contributed first-person sense portraits showing what their own sensory experience feels like from the inside.

This is not an intervention study. The authors are upfront about this and call for future research to test the specific techniques they are recommending.

Their Recommended Clinical Techniques

1. Sensory Stability

Build the therapy room to minimize sensory disturbance. Keep ambient sound low, never shout, avoid very high or very low vocal pitches, supplement words with visuals. Avoid bright lights, strip lights, flickering, and loud patterns. Wear simple block colors. Skip room fresheners, scented deodorants, and perfumes. Have weighted items and textured fidgets available. Have a safe-space option like a tent. Do not initiate physical touch but be open to it if the child comes to you, and use firm rather than gentle pressure if touch happens.

2. Tailored Interaction

This is about how the therapist uses their own body and voice. The advice is to start minimal. Just be in the space without expectations. Keep your body language non-threatening but open, and position yourself at or below the child’s eye level.

The paper introduces a concept called vitality, which comes from the work of psychiatrist Daniel Stern. Vitality is the energy or quality of how you do something. You can wave your hand excitedly, sadly, or in panic. The action is the same but the vitality is different.

Research has shown autistic kids often have trouble reading typical vitality cues from non-autistic adults. So the paper recommends making your body language clearer and more deliberate.

Pause, then make a clear gesture, then pause again. Exaggerate your movements when appropriate, or theatrically shrink them down to a whisper-sized motion. Add expressive sound effects (sighs, bubbly happy noises, sinking “huh” sounds for disappointment), because research suggests visual information alone is often not enough.

For voice, keep things quiet to start, use simple words, give time for the child to respond, and use a melodic storyteller voice rather than a flat monotone. Some autistic kids respond better to singing-style speech than regular speech because of how their brains process music.

The paper also notes that some autistic kids prefer being addressed by name rather than pronouns (“Sally is going to get the paper” instead of “I am going to get the paper”), but this varies child by child.

3. Tailored Empathy

This is one of the most important and most challenging parts of the paper. The authors strongly recommend therapists STOP labeling autistic children’s emotions. Saying things like “you look angry” or “that must feel scary” can be inaccurate, can train kids to disconnect from their actual experience, and can lead to a kind of masking where they learn the “right answer” rather than knowing themselves. The paper argues this can actually harm autistic kids.

So instead, they recommend behavioral empathy which is just describe what you see. “You’re walking, slow, heavy feet, shoulders and head hanging down” instead of “you seem sad.” “Bali threw the ball hard, her teeth are tight together” instead of “you seem angry.” This shows the kid you see them without forcing your interpretation onto their experience.

They also recommend reflecting on broad valence states (a sense of okay versus not okay) using four feeling-shapes: too much-ness, not enough-ness, stuck-ness, and just-not-right-ness.

The paper does not say to never label emotions. With older kids who are emotionally literate, or when a kid uses emotion words first, it is fine to engage with that language. They also note that within play, where the kid is controlling characters, it is safer to label emotions because there is distance between the play world and the kid’s real body.

4. Playful Mindfulness

This technique is adapted from Kelly Mahler’s Interoception Curriculum to fit child-centered therapy. The goal is to help autistic kids become more aware of body sensations and connect those sensations to actions that help them feel better. Remember interoception is the sense of what is happening inside your body. Many autistic kids have differences in interoceptive awareness, which means they might not realize they are hungry until they are starving, or they might not catch the early warning signs that they are heading toward a meltdown.

The technique has six parts.

1. First, set up the room with materials that create strong body sensations: sand, water, slime, putty, ice packs, hand warmers, vibrating toys, yoga balls, mini trampolines.
2. Second, notice one body part at a time, following the child’s play. Hands in the sand, feet on the trampoline. This keeps the cognitive load small.
3. Third, support different ways of expressing. Some kids use words, some draw, some use sounds. Have cards with sensation words (hot, cold, sticky, itchy) and color cards available.
4. Fourth, use questions with curiosity. Soften them with phrases like “I wonder” or “maybe,” and combine with behavioral observations. “Dave’s feet tapping in the water, I wonder what Dave’s feet feel like just now?” Always include open-ended options so you are not leading the kid to a specific answer.
5. Fifth, bring awareness to sensations and valence states, starting with whether something feels good or not good, comfortable or uncomfortable.
6. Sixth, accept all responses. Whatever the kid says, repeat it back without judgment, even if it surprises you. The point is curiosity, not getting the right answer.

After kids get good at noticing external body parts, you can slowly move to internal ones (lungs, heart, stomach), but only if they are ready. Eventually you help them connect body sensations to needs.

For example, restless legs plus tight belly equals need to use the bathroom. Angry feeling plus heavy head equals need to rest. These connections become tools the kid can use throughout their life.

5. Tailored Vocabularies of Feelings

Instead of forcing a kid to learn standard emotion words like sad, angry, anxious, happy, you help them build their own personal vocabulary based on how they actually experience things. The paper gives an example. A kid draws “big red zaps” to describe a feeling they get from certain noises. The shared understanding becomes: big red zaps means put on the noise-reduction headphones and go to the safe place. The kid does not need to learn to call this feeling anxiety or fear. Their personal label works just as well, often better.

Over time, the child builds a whole personal vocabulary. “Black belly blob” might mean eat a snack. “Metal lines and teeth” might mean drink water. “Fairy belly” might mean go to the trampoline.

This is especially powerful for catching the early warning signs of overwhelm. One of the autistic authors describes how blurry pinpoint vision and warbly sound are her first signs that a meltdown is coming. A kid with similar experiences could create a personal signifier for that state (an image of a ball on the edge of a cliff, a hand signal, a one-word label) and use it to communicate with the adults in their life before things escalate.

Researchers’ Conclusions

Their main conclusion is that child-centered therapy with autistic kids needs to be sensory-informed at its core, not as an afterthought.

Therapists need to adjust their environment, their bodies and voices, their empathic language, their attention to interoception, and their assumptions about emotion vocabulary. When this is done well, therapy can reduce dysregulation and build real connection without forcing the child to mask or perform neurotypical emotional fluency.

They are also clear that these are recommendations meant to augment existing therapy training, not replace it. Therapists should still be trained and registered in their primary modality.
