Dr. Cooper is an expert on Sensitive Sensation Seekers (people who are both highly sensitive and high-sensation seekers). These are mostly highlights for myself.
Sensation seeking can be thought of as a greater willingness and openness to approach new situations. It’s a trait defined by the seeking of “varied, novel, complex and intense sensations and experiences”. This appears in four ways: thrill and adventure seeking, experience or novelty seeking, disinhibition, and boredom susceptibility. You don’t need to be high in all four aspects to be HSS, and it’s common that you identify more strongly with one or two (one HSS child might enjoy riding their bike fast or jumping off chairs while another might enjoy field trips and getting lost in museums). When you’re both sensitive and sensation seeking, physical thrills might appear in more moderate ways like carnival rides. For the sensitive child, it’s the intensity of the experience that’s thrilling, even if the overall adventure may seem less so to others.
“It’s like the story of the cat who let you pet him five times, but not six. On six, he bites.”
Experience and novelty seeking is the biggest crossover between HSS and HSP. Disinhibition is often less of a factor because sensitivity causes children to pause. It’s like being pulled in two directions at once. The trait is largely heritable (58%) and is backed up by studies done on twins—identified as the DRD4 gene, the “wanderlust” gene, or the “Star Trek” gene. Where HSPs make up around 15-20% of the population, 30% of HSPs also identify as HSS. And there’s an evolution reason for this—the greater our range of behaviors, the greater our ability to perform well in context-specific ways.
In modern society, one interesting thing about these combined traits is that one is obviously more acceptable in western society (HSS). There’s also a gender divide—caregivers want to “correct” sensitivity in boys and “correct” sensation-seeking in girls. That’s why I really appreciated Dr. Cooper’s emphasis on the importance of embracing non-conformity as a means to happiness throughout this book. The sensitive sensation seeker is likely to be far less interested in fulfilling other people’s notions of what our lives should be like and how we should live them.
While sensation seeking traits can sound dangerous on their own, I really enjoyed reading about the benefits of the combined traits of HSS and HSP. HSPs might overestimate risks, whereas HSS might overestimate them. And HSS HSPs may feel a tug of war within. One person talked about it as the elusive “optimal level of stimulation”—similar to that sweet spot on a tennis racket. It just means we’re much more likely to weigh risks before taking them. Which can allow an otherwise sensitive person to push themselves outside their comfort zone and experience more of life.
As a couple of side notes, I also really enjoyed the sections about the theory of positive disintegration (no pain, no gain), age as a construct, and transcendental feelings.
