Re-sharing this Polyvagal Institute-approved graphic for you to study, refer to, and share!
☑️ This diagram was reviewed and approved by our co-founder, Dr. Stephen Porges, himself.
We hope this graphic helps to deepen your understanding of Polyvagal Theory and supports you wherever you may be on your personal and professional journey.
Why did we create this version of an ANS graphic? Well, sometimes Polyvagal Theory is misrepresented in the infographics that spread widely across the internet. Some illustrations ignore the very important hybrid states you'll find here; even more forget to show that these states happen on a continuum. And very few mention that behavioral reactions differ greatly depending on whether we detect an environment of safety or one of threat.
In our portrayal of the Autonomic Nervous System States, we've included lots of details to give you an even more comprehensive polyvagal-informed lens.
