highly sensitive person

Highly sensitive person (abbreviated HSP; sometimes capitalized Highly Sensitive Person in the popular press) is the psychology term first popularized in the mid-1990s to denote a person having a high measure of the innate trait whose scientific name is sensory processing sensitivity (SPS). Here, sensory processing refers to what occurs as sensory information is transmitted to or processed in the brain. SPS is measured by the Highly Sensitive People Scale (HSPS), which can be divided into subscales.
