All people are born with temperaments. About 20% of individuals (and over 100 other species) are born with the temperament of high sensitivity, also known as environmental sensitivity. Individuals with environmental sensitivity can thrive and learn to optimize the trait. In general, a person with the temperament:
Thinks and processes deeply
Notices subtle stimuli
Feels deeply
“No one processes anything deeply without an emotional motivation.” - Dr. Elaine Aron
Is more easily overstimulated
