Polyvagal Theory: A biobehavioral journey to sociality
Open accessAbstract
A polyvagal perspective clarifies the neurobiological and biobehavioral shifts that occurred during evolutionary transition from asocial reptiles to social mammals. This transition enabled mammals, unlike their reptilian ancestors, to derive a biological benefit from social interactions. This innovation enabled social behavior to function as a neuromodulator that could efficiently regulate and optimize autonomic function to support homeostatic processes. This journey is highlighted by the phylogenetic transition during which the autonomic nervous system was repurposed to suppress defensive strategies to support and express sociality. The product of this transition was an autonomic nervous system with capacities to self-calm, to spontaneous socially engage others, and to mitigate threat reactions in ourselves and others through social cues. Thus, social behavior became embedded with specific neurobiological processes that had capabilities to support homeostatic functions leading to optimized health, growth, and restoration. Polyvagal Theory emphasizes sociality as the core process in mitigating threat reactions and supporting mental and physical health.

The cited source says what the claim attributes to it.
In the citing paper
“This suggestion is supported by Porges” polyvagal theory (Porges, 2011, 2021), which characterizes the (myelinated) vagus as the foundation for the social engagement system, facilitating the experience of safety outside of awareness (neuroception).”
From The Complex Construct of Wellbeing and the Role of Vagal Function (2022) · cites this paper as Porges, 2021
The cited source says what the claim attributes to it.
In the citing paper
“According to polyvagal theory (Porges, 2011, 2021), the myelinated vagus in combination with other cranial nerves provides a “vagal brake” over the phylogenetically older sympathetic nervous system and unmyelinated vagus facilitating social engagement and interaction, and this process is outside of awareness.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
