In December I release some of my previously recorded Patreon bonus episodes as a treat for myself and my listeners. In this one I take a look at the updates to Elaine Aron's theory about HSPs (highly sensitive people) included in the 2020 re-release of her 1990s classic The Highly Sensitive Person, including new research on HSPs. I then discuss the similarities and differences between Aron's theory and Dabrowski's on the five types of OEs (overexcitabilities), and why I prefer Dabrowski's take on high sensitivity. Enjoy, and Happy New Year!
