Wired to Feel: Autism as a Condition of Sensory Surplus

by Sarah Bergenfield, Martha Sweezy

Powerful skills grounded in internal family systems therapy (IFS), polyvagal theory, and neuroscience to help you navigate your autistic brain, body, and mind.

There’s a saying: “If you’ve met one autistic person, you’ve met one autistic person.” Autistic individuals are as varied and different from one another as non-autistics. The difference is that we are often measured against societal standards we cannot functionally meet. Before we can navigate an ableist world and create the change needed to thrive, we must first understand our unique neurotypes and sensory sensitivities, and learn to feel at home in our autistic bodies.

In this groundbreaking book, autistic psychologist Sarah Bergenfield explains how and why autism is an embodied condition of sensory surplus—a conclusion she has reached through personal experience and empirical evidence. Psychotherapist Martha Sweezy joins Bergenfield in offering an adaptation of the internal family systems (IFS) therapy approach, as well as skills grounded in neuroscience and polyvagal theory to help you manage the sensory disorganization caused by an overwhelming world, so you can understand and advocate for your needs and cultivate lasting self-acceptance.

Autism is a condition of perceptual diversity—characterized by differences rooted in heightened sensory awareness and intensity, and experienced simultaneously in the body, brain, and mind. Our responses to sensory stimuli, changes in routine, and lack of predictability manifest as the symptoms that others may observe, such as difficulties with communication, socialization, shutdowns, and sensitivities.

This book will guide you as you let go of the negative effects of being marginalized, othered, shamed, or stigmatized—so you can reclaim your confidence, live authentically, and flourish.

As a psychologist and IFS/IFIO therapist who works with mixed-neurotype couples, I came to Wired to Feel with both professional interest and genuine curiosity. From the very first pages, I found something I would call rare: a vivid, nuanced description of the felt experience of being autistic, written from the inside out.

As a non-autistic person, I found this profoundly expanding. As a therapist, I found myself thinking of my clients who would feel deeply seen having their experiences named and understood so clearly. Sarah Bergenfield, writing from lived experience, shares vulnerable and moving anecdotes that echo what so many of my clients say. The pairing of precise naming with a compassionate, parts-based approach to healing is where the book shines: it brings together elements that help autistic people and non-autistic people alike better understand the autistic experience and alleviate the shame that so often accompanies existing in a neuronormative culture.

For non-autistic people, I think the book does something equally important: it interrupts the social assumptions that maintain a pathologizing stance. Bergenfield and Sweezy’s observation that “friendly” may look quite different depending on one’s neurotype, and that this reflects not a rejection of connection but a difference in its expression, is the kind of reframe that can genuinely shift how non-autistic people understand their own assumptions about communication and Self. This insight into the non-autistic end of the double empathy problem is invaluable.

Overall, Wired to Feel is a deeply important contribution to the therapeutic literature on autism. It supports autistic people in feeling understood and less alone, while also equipping non-autistic people to meet them with greater empathy, respect, and clarity. For anyone looking to better understand the autistic experience, this book is essential reading.

I have to start with saying that I’m pretty shocked and frustrated at the vitriol in some of the reviews.

This book is focussed on the intersection of Ifs and autism.

It feels very clear that some of the reviewers are not aware of both of these categories at the same time

I am only halfway through the book, but I’m experiencing it as vulnerable, courageous, tender, and informative.

I will come back and write a more comprehensive review, but I just wanted to support the authors. This book is still a newborn only in publication for a few weeks and I encourage you if you have curious parts to take your time wading into the warm waters of this book.

I really appreciate the range of examples that helped to expand our consciousness of how dynamic and nuanced autism is

The only feedback or criticism I have in this moment is that it centres only Sarah’s experiences I really appreciate the voice in the book and the range of experiences that she has so generously lent to the book and I hope to hear more on this rich topic moving forward.

Sending lots of tenderness to the community and anyone who wishes to enjoy this book

"Wired to React: Autism as an Impairment of Prediction"

I have only read up until the end of the first chapter, however, I predict that this book will be a slog, despite its shortness. I am rating 3 stars for now so as to not be overly harsh to a book I haven't finished. I just have to say something. I want people like me to know what they are getting into.

The first chapter is really fixated on Autistic people having impaired prediction. Based on this and skimming later chapters, this seems to be the premise of the book.

The book is ostensibly for Autists interested in a neuro-affirming perspective. However, that vision seems muddied by misunderstanding and/or cowardice. The book has yet to escape the prioritization of Autistic deficit. The first chapter starts by using second-person ("you") language to refer to, frankly, an imagined "normal" reader. Once it starts talking about us Autists, it drops the "you" language, referring to "the autistic brain" in third-person.

Here is a quote from that part:

"Rather than moving flexibly through each moment of the day, updating the brain's predictive model as needed, the autistic brain focuses on the current, ambiguous sensory data."

This dichotomy is both vague and internally weak. What stops a person from moving flexibly through ambiguous data? What stops a person from updating their brain's predictive model using the current moment? What does this even mean?

Unlike whoever authored this chapter[1], I do not assume apparent inflexibility is the result of an inherent inflexibility.

The way I explain it, Autistic people are like liquid water and Allistic (non-Autistic) people are like ice. A bottle of water is more apparently constrained. You are likely to identify it by its constraint ("that is a bottle of water"). However, the liquid water itself, behind the bottle of routine and familiar environment, is more flexible than the ice. When poured out of its bottle, it spills all over the place. If it were to feel, it may feel completely unlike it's usual self, and experience distress. The ice benefits less from the bottle, and if poured out of it, may simply hit the floor, intact.

Notice how this explanation is understandable and makes internal sense and seems to come from an Autistic perspective? Yeah.

Also notice that both the liquid water and ice have strengths. The liquid water is adaptable. With support, it can experience a broad range of being. In beakers, in mugs, in tubes, etc. The ice, assuming constant temperature, can be moved to different places with little inhibition, since there is no worry about what container to put it in.

This book so far has been making me feel ashamed to be Autistic. It is teaching me I'm not just unstable: I'm also inflexible. I am the worst of both worlds. That makes me sad.

Also, IFS has yet to be mentioned outside of the testimonials at the beginning. No mention in the forward, the introduction, or the first chapter. I see bits that can be foreshadowing (Autistic from "autos" meaning "self") but I'm disappointed as an Autistic system who got the book because I'm interested in IFS. The first chapter was misused. I would love to hear a clinician talk about IFS from an Autistic perspective, so get to that. I don't need another dump of insensitively framed autism-research discourse and rehashed Aspergian lore.

I want to finish this book. I may update. I hope there is enough good in here for the purchase to feel worth it. I did relate to Sarah's introduction and underlined parts I thought were well-said or representative. She says, "Autistics are not disconnected from other people and life. We are perceptually diverse."

More of that please.

[1] This book has two others, one of whom identifies as Autistic. The Allistic (non-Autistic) author may be to blame for some of the awkward delivery to a supposed Autistic audience.

Edit: This book used to be called "Embodying Autism: Make Sense of Sensory Surplus and Embrace Who You Are with Neuroscience and Internal Family Systems." I pre-ordered it when it was called that. The shift to broader, vaguer marketing may mislead readers. One review expresses frustration at the IFS content in this book despite this being an IFS book. The publishers were willing to risk this disconnect and I find that unfortunate.

This book was INCREDIBLY frustrating. The premise is extremely exciting: positing an autistic neurotype as experiencing sensory input at heightened levels, this being a cause of autistic perceptiveness and emotional breadth/depth and overwhelm, burnout, and reactivity.

The book, which is short, spends only a scant amount of space and energy discussing this, infrequently in a rigorous fashion. The vast majority of the book is spent issuing a dogmatic sales pitch for Internal Family Systems, a framework that I find completely alienating. If you don't, congratulations; you may like this book. However, as someone who really hates IFS and finds it impossible to implement, I was very disappointed to discover the book's promising premise being cast aside for 120 pages of insistence that I would LOVE IFS as an ~Autistic System~. It was irritating to be sold something as an exploration of a rigorous new framework, and to instead get this. It's not JUST that the book assumes that IFS is a universally applicable modality--it's also that it straight up treats the metaphoric "parts" framework as both literal and definitive. Just as you have a liver, so too do you have FIREFIGHTERS living inside you. PLEASE.

This is actually only one of several ways in which a book that purports to understand that autistics are multitudinous and each person unique consistently generalizes the group in inappropriate and unhelpful ways. Several things that really got my goat:

1) It addresses its descriptions of [an] autistic experience to "you," telling the reader "you" feel this, "you" have experienced this, "you" perceive the world in this specific way and react to it with these emotions, "you" have been punished for this specific behavior, "you" have these IFS Parts that do THIS thing, "you" can picture every pore of a clementine. Respectfully, you do not know me, and this is not a professional or clinically rigorous way to approach education to a broad audience. Your reader could be so many kinds of autistic person, so why is the hyperspecific consistently generalized? You're doing bad science, you're doing bad psychiatry, and you're just plain wrong!

2) A lot of the book's assertions about autistic "umwelt" seem to be drawn from Sarah Bergenfield's personal experience, which is made more explicit in the excerpts that are literally from her perspective and vignettes from her memories. The personal perspective on its own I don't mind - I love Megan Anna Neff's books on autism because they are written by an autistic clinician, but Neff is very good at using her experience as an occasional, carefully utilized bolster to her clinical experience, whereas Bergenfield seems to be unable to get out of her own head and entertain the notion that, as she herself says, all autistics are different from each other.

3) I don't love that they repeatedly assert that language delay is fundamental to all autistics. It is not.

4) I dislike even more their assured stance on diagnosis, which they seem to see as a clear dividing line between a miserable "before" and a healing "after," attainable for all autistics, necessary for loving yourself as an autistic, and an immutable science. They say nothing about self-diagnosis, and I mean nothing--they don't disagree with it, they don't embrace it, they don't acknowledge the important if embattled role it plays in the autistic community, in which both individuals and the group must wrestle constantly with the extreme self confidence and oft proven biases and shortfalls of the psychiatric establishment.

I've read some wonderful nonfiction about autism, and would strongly recommend both Dr. Neff and "Is This Autism?" and its companion book by Donna Henderson et al. But this? It was a great premise, a few lovely bits of strength-forward rather than deficit-forward descriptions of autism, and then a whole lot of calling Richard C. Schwartz "Dick." We all know Dick, right? From Internal Family Systems, the thing everyone agrees is the most good?

Really disappointed.

I received a free copy from the publisher through Netgalley and voluntarily reviewed it.

When I saw this one on Netgalley I knew I wanted to read it. I've read and and listened to a lot of content about autism ever since receiving my autism diagnosis and I heard about IFS and how this could be helpful, but knew very little about it. So I was excited to see what new information this book had for me.

I found this a very informative book, the whole theory about the prediction model explaining some parts of autism was very interesting and made a lot of sense to me. I feel like I either get overwhelmed as I don't know what to expect and everything seems possible or I create these very strict prediction models that hardly ever survive contact with reality. I really enjoyed reading about that.

Then there was the whole part about Interpersonal Family Systems, I didn't know a lot about this and I liked that the author started at the basics. Even so I would've liked a bit more about it, I just felt like my brain couldn't fully comprehend it all and I would've liked some more concrete examples about how the author talked to her parts and resolved some specific thing or behavior. The further I got the more my understanding grew and I think this framework could be very helpful, but I feel like I need more information to full grasp the concept.

Besides that there are chapters about masking and burnout as well as how to handle getting a diagnosis. These were topics I was already more familiar with, so the most interesting part of those chapters was the author's perspective on these and the way she tied that back to the IFS parts system. I also liked how the author talked a bit more about her own experiences in these sections in italics that detailed things in her life.

To summarize: This was a great book and while I've read a lot about the topic of autism already this one provided me with new knowledge and information. I liked reading about the prediction model theory as an explanation for some parts of being autistic and that made a lot of sense to me. It was such an interesting way of looking at it. I didn't know much about IFS before starting this book and I liked learning a bit about what that entailed, although I would've liked a few more concrete examples as I had trouble fully grasping it. This did get a bit better as I got further in the book, but I still would've liked a bit more. I also liked how the author tied burnout, masking and getting your diagnosis back to the IFS system. And I liked the bits were the author shared her own life examples in these short sections in italics. All in all a very informative read that expanded my knowledge and one I can definitely recommend.

[Krupal · Rating 3 out of 5]

There were some helpful concepts mixed in with a more narrow clinical focus for this book about autism. I found it helpful to learn about the application of the predictive coding error framework to autism, as well as the integration of polyvagal theory. The authors focus on understanding overwhelm and functioning across environments. I also appreciated how the book explored autistic experiences across different domains like work, home, and social settings.
That said, the book leans heavily into Internal Family Systems (IFS) as the primary approach. While I do see value in IFS and think it can be beneficial, the book felt definitive, as though this modality stands above others. I would have appreciated a more balanced discussion of alternative approaches or a clearer acknowledgment of the diversity in therapeutic needs. Because of this, I’d most strongly recommend this book to readers who are specifically interested in applying an IFS framework to autism. This book offers useful insights within that scope, but may feel limiting if you’re looking for a broader overview of therapeutic approaches. I’d also suggest reading this book alongside therapy or clinical guidance (rather than a standalone resource).

Rating: ⭐️⭐️⭐️

Thank you to NetGalley and New Harbinger Publications, Inc. for a complimentary copy of this book. Opinions expressed in this review are completely my own.

Thank you to netgalley and the publisher for the ARC! For reference, I am diagnosed AuDHD (autism + adhd) and have a bachelors in psychology and nursing so the neurological, social, and health implications are familiar and relevant to me. This was interesting and informative. There is very helpful info, and refreshers about autism and how to embrace it. I appreciated a lot of the reframing the author offered, but a lot of this wasn’t necessarily new to me. I did find a majority of it striking though.

Very positive and enlightening approach to Autism...
