Highly Sensitive Person (HSP) Test

The term “highly sensitive person” (HSP) refers to individuals whose brains process sensory information more deeply than others, and therefore often become overstimulated and overwhelmed as a result. This neurological makeup is estimated to encompass 15-20% of the general population, but is generally misunderstood and often misinterpreted as shyness, inhibition, or introversion. The following Sensitive Person Test is based on the scientific research into this construct, as developed by psychologist Elaine Aron.

Are you a highly sensitive person? For each of the following items, indicate how strongly it applies to you below.

Question 1 of 26

I really immerse myself in the things that interest me.



The IDRlabs Sensitive Person Test is the property of IDRlabs International. It is based on the Highly Sensitive Person Scale, which is the property of the American Psychological Association.

The Sensitive Person Test is based on a widely used instrument that assesses this innate psychological trait, which is often referred to as “Sensory-Processing Sensitivity (SPS)” or the “Highly Sensitive Person” trait. This trait has been observed in numerous species and is thought to have developed as a type of survival strategy – observing and reflecting thoroughly before acting, rather than jumping into action or acting on gut instinct. Being a highly sensitive person in this sense indicates a distinct neurological disposition, and is not to be confused with being shy, introverted, nervous, or inhibited.
