What is 
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. Download and/or share the ANS diagram (at right, and translated in multiple languages below), which shows the three main states plus hybrid variations.

Frequently Asked Questions
about The Polyvagal Theory

  • What is the attendance policy for a course?
    Live/Hybrid courses: While specific course policies may vary, we typically allow one absence for a live or hybrid course and require watching the recording and/or sometimes submitting a reflection for the missed session. If a participant is absent for more than the permissible number of live sessions, they may no longer be eligible to receive their certificate. Self-paced courses: Attendance does not apply to self-paced courses as they are designed to be consumed when the student is willing and able to take the course. All material is pre-recorded content, reading, or individual assignments. Please note that if you are enrolled in a course that offers CEs (continuing education credits) and you have opted to earn them, specific attendance policies apply and must be adhered to in order for you to remain eligible to earn CEs at the end of the course. Contact us for details if you are unsure of the attendance policy for your particular course!
  • How and where are live sessions held?
    Live sessions are held online via Zoom. You will find your course Zoom link inside the course content on our Learning Platform once you enroll; email reminders with the Zoom link are sent to enrolled students. While having your camera on is not required, you are invited to turn your camera on during your live course session; this allows you to share in co-regulation with other learners and to build a sense of community.
  • What if I am unable to attend a live session?
    We upload recordings of our live course sessions to our Learning Platform within 72 hours for you to view. (Please see the attendance policy above.)
  • How can I tell what time the live session will be in my local time zone?
    To convert live course session meeting times to your local timezone, please use a conversion website like this.
  • Where can I find the course material?
    PVI uses a Learning Platform (LMS) called Thinkific. Upon enrolling in a course, you will receive an email invite to access the course in Thinkific. This is where you'll find all of the course materials, links, and class community.
  • Is this course accredited?
    PVI is the founding home of Polyvagal Theory, and we believe our courses offer the most accurate and up to date content about Polyvagal Theory and its many applications. There is no accrediting body for this type of curriculum. Our course descriptions will list any continuing education credits (CEs/ CEUs) or other professional benefits that might be available for the course (along with any applicable restrictions). If CEs are not listed for a particular course, then none are available.
