High sensitivity (also called Sensory-Processing Sensitivity) has been studied in kids and adults for over 60 years. It’s not a disorder; it’s simply a temperament type – one that’s shared by 20 per cent of the population, occurring equally among males and females.

Psychologist Elaine Aron’s secular book The Highly Sensitive Child has long been a go-to resource for parents. If you suspect your child may be highly sensitive, consult the checklist below of traits described in Aron’s book. No highly sensitive child will show all these traits, just a large number.

Please note though that to be considered highly sensitive, a child must show all of these five traits (which are also in bold in the full checklist below):

  • Intense emotional reactions
  • Deeply processes experiences
  • Highly empathetic
  • Easily overstimulated
  • Sensitive to subtle stimuli
