What is high sensitivity?

High sensitivity, formally called Sensory Processing Sensitivity, is an inherited temperament trait found in 15 to 20 percent of people, and in over 100 other species. It is not a disorder, a phase, or a flaw. It is a different way of taking in the world.

Four traits that define a sensitive nervous system.

Dr. Elaine Aron, the researcher who first identified the trait, describes sensitivity through four hallmarks she calls DOES.

D

Depth of processing

Sensitive people process information more thoroughly, noticing connections and implications others miss. This is the engine of their creativity, empathy, and insight.

O

Overstimulation

Because they take in and process more, sensitive nervous systems reach their limit sooner. What looks like a meltdown is often a system that is simply full.

E

Emotional responsiveness and empathy

Sensitive people feel their own emotions intensely and attune deeply to the emotions of others. They are often the first to sense when something is wrong.

S

Sensitivity to subtleties

A change in tone, a flickering light, a scratchy tag, a shift in someone’s mood. The sensitive system registers fine details that most people filter out entirely.

What sensitivity is, and is not.

Myth

Sensitivity is a weakness to outgrow.

Truth

It is an inherited, measurable trait that stays for life. The goal is understanding, not correction.

Myth

Sensitive kids are just being dramatic.

Truth

Their nervous system genuinely registers and processes more. The intensity is real, not performed.

Myth

They will be fragile and struggle in life.

Truth

With understanding and the right support, sensitive people are among the most creative, empathic, and conscientious.

Myth

Sensitivity is the same as anxiety or a disorder.

Truth

Sensitivity is a normal temperament trait. It can coexist with anxiety, but it is not a diagnosis.

Five fields of science, one curriculum.

Dr. Elaine Aron's HSP Research

Four decades of research establishing Sensory Processing Sensitivity as a measurable, inherited trait.

Polyvagal Theory

A map of the nervous system that explains why a sensitive body reaches shutdown or alarm more readily.

Attachment Science

How early relationships shape the way a sensitive child learns to regulate and reconnect.

Dan Siegel's Interpersonal Neurobiology

The science of how relationships literally shape the developing brain, moment to moment.

Epigenetics

How environment and experience switch genes on and off, and why context matters as much as wiring.
