Neuroception Through a Neurodivergent Lens

Libby Hill: I am delighted to be talking to the person behind Changing The Narrative About Autism And PDA Jessica Matthews. I’ve been following her for a while now and look forward to her posts. She wrote an article last year which really resonated with me. Welcome Jessica!

Jessica Matthews: Hi Libby. Thank you for asking to interview me about neuroception and PDA.  

Libby Hill: Thank you for accepting!

My first question for you relates to the term neuroception: can you explain what neuroception means?

Jessica Matthews: The term neuroception was coined by Dr Stephen Porges who describes neuroception as “how our neural circuits distinguish whether situations or people are safe, dangerous, or life threatening. If our neural circuits perceive a threat; the principal human defence strategies are triggered” (Porges, 2004).

Simplified a little, we can say that through our senses, neuroception is the process by which our nervous systems, determine whether we are safe or unsafe.  

In 2004, Dr Porges wrote an article called “Neuroception: A Subconscious System for Detecting Threats and Safety”. This was seminal for me as a young Psychology graduate. It really spoke to the experiences I’d had working with Autistic young people, as well as to the work I had moved onto with Looked After Children.  What I couldn’t have imagined, was how deeply I would re-connect with the implications of neuroception ten years later, when I became a parent.

Dr Porges’ Polyvagal Theory explores how our neuroception of threat triggers defensive responses. These present in the form of adaptive behaviours in that they have a protective function. Unfortunately, adaptive behaviour is often misinterpreted as challenging behaviour and treated as such.  When we become Polyvagal informed, the adaptive nature of behavioural responses becomes much clearer, as does our understanding of the underlying feelings of threat. “The autonomic nervous system (ANS) has two primary systems; the sympathetic nervous system and the parasympathetic nervous system. (Schwartz, 2016).  Polyvagal Theory explains how the vagus nerve (the longest nerve of the autonomic nervous system and the main component of the parasympathetic nervous system) has two distinct branches; ventral and dorsal. These can be more accessibly referred to as our ‘safe and social’ state (ventral), and our ‘freeze’ state (dorsal vagal), where freeze includes a state of fright, dissociation, immobilisation, collapse and fainting.  The vagal system contrasts starkly with the sympathetic adrenal system; which generates the mobilising behaviours which form our ‘fight or flight’ state. The ANS also has ‘mixed states’, one of which is fawning.

I could see from an early age that my son’s defence strategies were triggered by certain sensory stimuli and at a slightly later stage that he was also triggered by everyday demands. I knew instinctively that he had some differences in sensory processing, because I did too.  His responses to demand stimuli resonated with me and confused me all at the same time, until we later came across the PDA literature.

It then became really important to us to understand more about the cues that were calming or threatening to our son’s nervous system.  We wanted more understanding so that we could honour his responses, without feeling so challenged by them and as such, become more able to support him to feel safer in his environment and relationships.  
Polyvagal Theory makes the important distinction between perception and neuroception. Perception involves awareness and usually some degree of interpretation at a conscious and cognitive level, whilst neuroception is reflexive; an automatic process, without conscious thought.  “Before the brain understands and makes meaning of an experience, the autonomic nervous system, via the process of neuroception, has assessed the situation and initiated a response” (Dana, 2018).    

Libby Hill: What can we do if we suspect that neuroception is an issue?

Jessica Matthews: This is such an interesting question because it depends so much on our perspective. When we categorise particular variations in neuroception as ‘faulty’ or otherwise, we align with a medical model. This feels incongruent for me, so I had been using the term ‘highly sensitive neuroception’ which I set out in my article Highly Sensitive Neuroception May Be At The Heart Of PDA     More recently, the term ‘finely tuned neuroception’ was introduced by Tracy Farrell (2020).  This phrasing feels even more closely aligned with a respect for how our nervous systems protect and safeguard us, exactly as we need them to. Within a neurodiversity framework, I see differences in neuroception as naturally occurring and part of a response system that is “an expression of a neurobiological process”, (Porges, 2004) in social context. 
Individual’s neuroception of threat and safety will vary because “our nervous systems are all shaped a bit differently” (Dana, 2020).  When we consider neuroception as a response to the features in our relationships and in our environment, we can begin to consider neuroception within the context of a social-neuroscience model.  From here, we can begin to integrate considerations about how the social world also impacts our neuroceptive responses.

Understanding neuroception outside of a medical model has helped me to understand both my own and my son’s neuroceptive responses through a polyvagal lens, supported by the ‘Golden Rule of Neurodiversity’. The latter is written about by Dr Nick Walker (2015) who sets out the crucial nature of “respect[ing] the bodily, sensory and cognitive needs of others as you would want your own to be respected, whether or not you understand the reasons for those needs”.  This last point for me, speaks to neuroception as well. For there are many times when we struggle to recognise or understand what our own neuroception of threat is about, let alone what our child’s may be related to. Respecting and seeking to understand neuroception, as complex as that is, is very helpful indeed.  For neuroception can be seen as part of an “implicit bodily process out of which our narrative arises” (LaPierre, 2007), and is in many ways an experience in the body that has no words.  Much like interoception, it is linked to micro-sensory experiences that can be felt in the body, sometimes very powerfully, but are very difficult to describe. 

Polyvagal Theory teaches us how important it is to understand our nervous systems more deeply.  As parents, carers and professionals, our nervous system state is always the starting point, the platform from which we send out neurophysiologically shaped cues of safety or threat to our children. If our nervous system is in a defensive state, we will unintentionally send out unsafe and unsettling cues. When children are struggling themselves, their neuroception will be heightened and at its most finely tuned.  
Being on this journey, has required me to develop my own somatic awareness and to start to honour and nurture my own nervous system, in a way that I hadn’t before.  Doing this has been central to supporting my son’s nervous system and his sense of safety.  The goal is not to always be in our safe and social state, none of us stay in one state all the time.  We live, we feel, we respond. Nobody would benefit from having robotic parents who appeared to glide through the day, untouched by humanity. Rather, the goal is to strengthen our own safe and social state, so that we can spend more time there and also find our way back there more easily.  From our safe and social state, we can also repair any relational ruptures with greater ease, which means that those inevitable times when we all lose our calm as parents, can be resolved with our children being able to return to their safe and social state too. Doing this, helps to prevent children from being left alone with unresolved stress that can get stuck.

Becoming aware of what our different nervous system states feel like, how differently we communicate within each, and how differently our children respond to us when we are in each state, is central to how our children feel when they are with us.  Once children’s defence strategies have been triggered, they need to receive really strong cues of safety and co-regulatory support to be able to return to their safe and social state.  This responsibility, to be regulated as caregivers, is a critical one. For Neurodivergent children, the world can be a very demanding and overwhelming place, so parents, carers and educators need to be able to open their hearts and arms a little wider. 

As adults, we need co-regulatory support too. This need is a human one, and it is lifelong.  Polyvagal Theory teaches us that connection is a biological imperative.  None of us were designed to navigate this world alone, or to parent in it alone.  However, in a world where we are all under more pressure, juggling more, with less time for stillness, it is not always easy to find this. For many Neurodivergent families, this can feel even more challenging, as we are frequently misunderstood and often isolated with the challenges we face. Finding a community of supportive adults who really “get it”, is critical.

As a Neurodivergent adult and parent of a Neurodivergent child, I have also needed to really think about the heritage of my own nervous system.  It has been really important for me to start a process of re-parenting my nervous system and to recognise some of the younger parts of me, that needed co-regulation, especially those parts of me that needed embracing as Neurodivergent at a time where, without fault or blame, such insight was not on anyone’s radar.  None of us can know, what we do not know.  This process is challenging and can be a painful one. It can often be a time when seeking our own support from another safe adult can be really helpful.

The adults in children’s lives, play a central role in shaping their nervous systems.  Self-regulation is predicated upon receiving sufficient and consistent co-regulation from birth.  The state of adult’s nervous systems is central in this, for if the adult and child are both starting off in a fight or flight state, the path ‘home’ becomes a little uphill.  Crucially we need to appreciate the science of Polyvagal Theory here, which shows us that you can’t ‘fake’ safety cues.  It isn’t possible to ‘paint on’ a smile or ‘act’ in a calm manner.  You can’t kid the nervous system, because neuroception will always detect incongruent cues in another person’s nervous system. Children generally, but particularly those with finely tuned neuroception, are very skilled at cutting through our facades. This means that authentic communication is not just advisable, it is crucial.   
Libby Hill: What would you say to parents who are wondering if this is their fault?

Jessica Matthews: There is no fault or blame in any of this.  Finely tuned neuroception in the context of PDA, is also in the context of being Autistic, which is defined beautifully by Walker (2015) as a “genetically-based human neurological variant”.  There is no ‘disorder’ here, no “faulty characteristics” just differently shaped nervous systems, experiencing the world in different ways, each seeking safety and connection from another, sometimes struggling to do so when immersed by fear and threat. For Neurodivergent individuals, the world presents many more danger cues, especially in the form of intense sensory, social and demand stimuli.  Therefore, in unsupported environments, it is much harder to access safety cues. The cues of safety that are found in connection with others, become less accessible when the nervous system is in a defensive state.  For Autistic people with a PDA profile, safety is highly contingent on the need to be autonomous and free and with this comes a distinct skill for detecting agendas, directions and demands. 
When we look at PDA through a polyvagal lens, we can see how, via neuroception, demands are often coded as threats.  When we understand PDA as a protective response system, that defends the individual’s need for autonomy and freedom, within a world that is already full of overwhelming multi-sensory stimuli, it is much easier to understand how frightened and overwhelmed individuals with PDA feel, a lot of the time.  It also becomes easier to appreciate how, when environmental and relational adaptations are made within a framework of deep understanding, that this very same group have the potential to thrive and achieve amazing things. 

It is really important that we prevent ourselves falling into the trap of conceptualising finely tuned neuroception as ‘faulty’ or ‘problematic’. It is much more helpful to understand and provide supportive and nurturing contexts, that prioritise emotional well-being.  Many Neurodivergent families have likely experienced more than their fair share of assessment and judgement and so it is really important that blame narratives are quashed.  When we consider finely tuned neuroception in the context of Autism more broadly, we need to integrate the current evidence which “indicates that the central distinction is that autistic brains are characterized by particularly high levels of synaptic connectivity and responsiveness.  This tends to make the autistic individual’s subjective experience more intense and chaotic than that of non-autistic individuals: on both the sensorimotor and cognitive levels, the autistic mind tends to register more information, and the impact of each bit of information tends to be both stronger and less predictable” (Walker, 2015). 

Libby Hill: Would you say we are teaching masking when we want compliance at school or to fit in with peers?

Jessica Matthews: I would say that in any setting where children’s neurological needs are not honoured and supported, that their nervous systems will be triggered into a defensive state. This can present as masking or as fight, flight, freeze or fawn.  All of these have a huge emotional and physiological cost to the child. You know better than most Libby, that when children don’t feel safe in their school environment, “their learning brain is hijacked by their survival brain” (Ham, 2017) and their nervous systems are put under tremendous pressure.  There are many amazing teachers who do everything they can to support their students.  However, our special educational needs and disability support systems remain underfunded and poorly resourced, whilst our education systems remain steeped in outdated behavioural theory. There is a lack of integration of current Autism research conducted by Autistic researchers, and research from neuroscience, psychology or child and adolescent mental health, all of which shows that when we are attuned to and nurture children’s emotional well-being and their individual neurological needs, we support their lifelong physical and mental health.  Whilst schools continue to use isolation, restraint, exclusions, rewards and punishments in an attempt to motivate children who can’t, rather than won’t, they fail to honour this evidence base and our children’s health and happiness. The time to embrace a paradigm shift and to become Polyvagal Informed is now.

Libby Hill: And on that subject, I’m really pleased to be able to share the news that you are writing an exciting book about Polyvagal Informed Parenting and PDA, which is due to be published by Jessica Kingsley Publishing in June 2022.  Is there anything you can share with us about the book before we end?

Jessica Matthews: Yes, absolutely.  I’m so excited about my book.  I’ve been working on its content for a while now and I was thrilled when Jessica Kingsley Publishing offered me a contract. The book will share the parenting approach that we have organically developed through a polyvagal lens, within a neurodiversity framework and with a growing understanding of our son’s and each other’s needs. This Polyvagal Informed Parenting approach has helped us to support our son to feel safer in what is a demanding world.  The book will provide an understanding of the autonomic nervous system, an accessible overview of Polyvagal Theory through a Neurodivergent lens.  It will cover a working understanding of how we offer, what I call the Polyvagal Informed Core Conditions (PICCs) across different aspects of PDA parenting.  I hope that the book will feel supportive to other families who may feel as lost as we did at the beginning of this journey.

Libby Hill: Thank you very much Jessica. I look forward to talking to you again at some point soon.

Jessica Matthews: Me too, thank you Libby. Speak soon.

PDA Awareness Day 2020

Can you believe that it’s five years since the first episode of Born Naughty was shown on Channel 4. Honey was the first person who I had come across who had PDA. I knew she was autistic but I knew it wasn’t typical autism. Thank goodness for an open-minded paediatrician who didn’t mind putting his neck on the line as well, to declare to the world that we felt she had PDA. 

It’s quite embarrassing looking back on my lack of knowledge of the wider implications of PDA, for example, I am heard to describe it as 'a mild form of autism.' How wrong was I? 

But I’m willing to admit that and I am not afraid to admit that I knew I needed to learn more. I have spent the last five years doing just that: talking to children and young people with PDA and listening to young people and adults with PDA plus listening to Parents of children and young people with PDA. 

I know so much more now than I did then but I also know there is so much that we need to know. Research is moving forwards but we need much more. How apt that it is actually PDA awareness day today. If you have a look at the PDA Society website they have a whole lot of quick tips and information to share with others here is a roundup of their most popular
