I think that this is an important time to pause and relook at Polyvagal Theory before continuing with Beyond Behaviors.

Polyvagal Theory: Current Status, Clinical Applications, and Future Directions (Porges, S. 2025)

“Social behavior and the capacity to manage challenge are dependent on the neural regulation of physiological state.” S. Porges


When I dove into Stephen Porges’s 2025 review of the Polyvagal Theory (PVT), I felt like I’d stepped into a crossroads where neurobiology, clinical practice, trauma science, and human experience collide. This paper isn’t merely a summary of three decades of work (all of which I have read); it’s a spirited defense of a paradigm that’s been both celebrated (by me) and contested (by others). What follows is an honest appraisal of what the article teaches us, where it sparks real insight, and where it may fall short, especially through the lens of evidence-based medicine and developmental neurophysiology. (I also went deeper into his 2022 paper in Frontiers in Integrative Neuroscience for the biophysiology of the ANS)

At its heart, the article argues that the autonomic nervous system (ANS), through a set of hierarchically organized circuits centered on the vagus nerve, is not just a background player in stress and homeostasis, but a core regulator of social engagement, physiological flexibility, and behavior. Dr. Porges situates his theory as an alternative and expansion to classical views that treat sympathetic (fight/flight) and parasympathetic (rest/digest) branches as functional opposites. Instead, he proposes a three-component hierarchy: the ventral vagal complex (VVC) supporting social engagement, a mobilization circuit mediated by the sympathetic nervous system or fight or flight state, and a dorsal vagal circuit that facilitates shutdown or immobilization under extreme threat…..

This week I sit down with Dr. Stephen Porges, a Distinguished University Scientist at Indiana University where he is the founding director of the Traumatic Stress Research Consortium. He is Professor of Psychiatry at the University of North Carolina, and Professor Emeritus at both the University of Illinois at Chicago and the University of Maryland.

He served as president of the Society for Psychophysiological Research and the Federation of Associations in Behavioral & Brain Sciences and is a former recipient of a National Institute of Mental Health Research Scientist Development Award. He has published more than 400 peer-reviewed papers across several disciplines including anesthesiology, biomedical engineering, critical care medicine, ergonomics, exercise physiology, gerontology, neurology, neuroscience, obstetrics, pediatrics, psychiatry, psychology, psychometrics, space medicine, and substance abuse. In 1994 he proposed the Polyvagal Theory, a theory that links the evolution of the mammalian autonomic nervous system to social behavior and emphasizes the importance of physiological state in the expression of behavioral problems and psychiatric disorders. The theory is leading to innovative treatments based on insights into the mechanisms mediating symptoms observed in several behavioral, psychiatric, and physical disorders.
​
He is the author of multiple books on his Polyvagal Theory: including the Neurophysiological foundations of Emotions, Attachment, Communication, and Self-regulation, as well as Polyvagal Safety: Attachment, Communication, Self-Regulation. His newest book cowritten with his son is called Our Polyvagal World, How Safety and Trauma Change Us. Dr. Porges is the creator of a music-based intervention, the Safe and Sound Protocol ™ (SSP), which is used by therapists to improve social engagement, language processing, and state regulation, as well as to reduce hearing sensitivities.

This is such a fascinating conversation. He brings the worlds of psychiatry and anthropological physiology into union for us to understand the why of trauma reactions and the future unwinding that is now possible. This is a must listen to conversation if you know anyone with trauma history.

Please enjoy my conversation with Professor Porges,

Review of Chapter 1 of Beyond Behaviors
by Mona Delahooke, PhD


“When we see a behavior that is problematic or confusing, the first question we should ask isn’t “How do we get rid of it?” but rather “What is this telling us about the child?” (MD 2019)


The opening chapter sets the stage for a quiet revolution in how we understand children who struggle. Dr. Mona Delahooke invites us to take a step back from the culturally and medically ingrained belief that children’s outward actions are reliable windows into their inner intentions – or what they really mean and want based on their actions. Instead, she asks, nay implores, us to adopt a more biologically accurate, compassionate, and clinically effective lens from which to view each child as they present themselves. Their behavior is communication from a developing nervous system striving for regulation and often stuck somewhere else, either frozen or in flight…..
