⛔ What this book actually is — and it changes how those 21 modules should read

It is not a monograph. It is a collection of interviews. The file's own credit lines say so, six times over:

Verified quotations

"This interview was revised by Stephen W. Porges for this book edition"
(probed — 6 occurrences, one per chapter 2 to 7)

The credits date the originals: April 2011 · April 2012 · February–March 2013 · March 2014 · winter 2010 · November 2011 — conducted for NICABM, GAINS and Somatic Perspectives, revised for the 2017 book. The interviewer's turns are in the text (Buczynski: …).

Three consequences:

1. ⛔ An interview is not a paper. Spoken, revised answers to a practitioner audience carry no

peer review and cite no data in place. Citing this book for a finding cites an interview.

1. ⚠️ The content is 2010–2014, published 2017. Anything time-sensitive should carry the

interview's date, not the book's.

1. What it is genuinely good for: the author explaining his own concepts in plain language, and

a glossary — which is where the crisp definitions below come from.

Identity

⛔ A defect this book revealed, and it was in our own tool. Because those credit lines are the only chapter markers and they sit at the end of the file, dossier_lecture.py v1.3 started its split there and left 67 340 of the 69 785 words — 96 % of the book — unscanned, returning 21 candidates instead of 399, with no sign that anything was missing. Fixed in v1.4 (the head of a file is now always scanned and declared as its own section) with a dedicated fixture. ⚠️ The four earlier summaries were checked against this: Barkley 0 %, Greene < 1 %, Haidt 1 %, Tomasello 0 %. Only this book was materially affected.

The definitions — the book's real contribution

Verified quotations

"Neuroception is not a cognitive process; it is a neural process without a dependency on
awareness." (probed, 1 occurrence)

Verified quotations

"Faulty neuroception might detect risk when there is no risk or identify cues of safety when there
is risk." (probed, 1 occurrence)

⚠️ "Might" is in the sentence. Faulty neuroception is offered as a possible reading of a mismatch, not a diagnosis.

Verified quotations

"Approximately 80 percent of the neural fibers in the vagus are afferent (sensory)."
(probed, 1 occurrence)

Verified quotations

"Only approximately one in six of the motor fibers are myelinated." (probed, 1 occurrence)

⚠️ The same anatomical figure appears as approximately 15 % in Polyvagal Safety (2021) — italicised here because that string is verbatim from the other book, not from this one. The two statements are consistent (one in six ≈ 17 %), but a module citing "15 %" from one book and "one in six" from the other is citing the same claim twice, not two sources.

Where the author limits his own model

Verified quotations

"are only positive, we are wrong!" (probed, 1 occurrence)

⛔ The full sentence warns against assuming vagal influence is only positive — the exact simplification that circulates downstream as vagal tone good, sympathetic bad (⛔ my formulation, not the book's). The author refuses it in his own popularising book.

Verified quotations

"We might end up interpreting a behavioral pathology as a behavior that might have been adaptive
in one setting" (probed, 1 occurrence)

Verified quotations

"Since auditory hypersensitivity is not specific to any clinical disorder" (probed, 1 occurrence)

⚠️ Said of a phenomenon central to the author's own intervention work: not specific to any disorder, and not a diagnostic criterion. A module using auditory hypersensitivity as a marker would contradict this.

---

Good for / must not be used for

Good for: definitions (neuroception, faulty neuroception, the anatomy figures); the author's own plain-language exposition; his explicit refusals of the simplified version.

• ⛔ Any empirical finding — this is an interview collection, not primary literature.
• ⛔ Vagal = good (⛔ my formulation) — the book says the assumption is wrong.
• ⛔ Auditory hypersensitivity as a diagnostic marker.
• ⚠️ Undated content: the interviews are 2010–2014.
• ⚠️ Double-counting the vagal-fibre figure across this book and Polyvagal Safety.
