I was first introduced to Porges’ Polyvagal Theory by Leslie Heywood’s (2011) article “Affective Infrastructures: Toward a Cultural Neuropsychology of Sport.” It’s really interesting to read Porges’ article “The Polyvagal Theory: phylogenetic contributions to social behavior” afterwards. Heywood used this theory in her understanding of sport models but after reading the original article I now see the theory’s potential to explain social behavior on the whole. In regards to culture shock, my specific interest at this moment, there are many quotable sections in the article that shed light on what might be happening neurophysiologically. If you can overlook the absence of Oxford commas, then give this article a look. It provides a workable framework for understanding psychiatric disorders and sociality in general.
