What is The Polyvagal Theory?

Polyvagal Theory emphasizes the role the autonomic nervous system - especially the vagus nerve - plays in regulating our health and behavior. Created and developed by Stephen Porges, PhD, the theory describes the physiological/psychological states which underlie our daily behavior as well as challenges related to our wellness and mental health. By applying Polyvagal Theory to our personal lives as well as to disciplines such as medicine, education, and management, we can understand how safety, co-regulation, and connection are paramount to a healthy human experience.

Polyvagal Theory in 60 Seconds

We challenged some of our most passionate and well-trained friends of Polyvagal Institute to define Polyvagal Theory in their own words in 20 seconds or less. Here's what they had to say...

3 Key Principles of The Polyvagal Theory

Polyvagal Theory has three defining principles: the hierarchy of the autonomic nervous system (ANS) per PVT, neuroception, and co-regulation. We've described each principle below in detail and if you'd like to learn more, sign up for a course or check out our free downloads in the FAQ's.

The Hierarchy of the Autonomic Nervous System (ANS) per Polyvagal Theory

Through the process of evolution the mammalian ANS has a primary repertoire of  3 principle states. These states functionally and adaptively shift according to how safe we feel at any given moment. The mechanism involved in shifting these states (see neuroception ) occurs beneath the level of conscious awareness. These states form an underlying neurophysiological foundation for our feelings and emotions. In reality, these states are not always independent, but may interact to form hybrid states, which support a continuum of behavioral reactions ranging from quiescence to mobilized actions within both safe and threatening contexts. See the diagram below that shows the three main states plus hybrid variations. Please download and share this diagram with others.
