“This two-system explanation of sensitivity also suggests two different types of HSPs. Some might have only an average-strength pause-to-check system but an activation system that is even weaker. This kind of HSP might be very calm, quiet, and content with a simple life. It’s as if the royal advisors are monks who rule the whole country/person. Another kind of HSP could potentially have an even stronger pause-to-check system but an activation system that is also very strong—just not quite as strong. This kind of HSP would be both very curious and very cautious, bold yet anxious, easily bored yet easily overaroused. The optimal level of arousal is a narrow range. One could say there is a constant power struggle between the advisor and the impulsive, expansive warrior within the person.”
