Genetic sensitivity moderates the effects of maternal stress during pregnancy on child behaviour with children that are genetically more sensitive being more affected by the quality of their prenatal environment.
Sensitive people are more strongly affected by both negative and positive experiences.
We conducted a genetic study of environmental sensitivity using a novel approach involving identical twins. Using these findings, we were able to estimate the genetic propensity to environmental sensitivity in two further samples and showed findings that were consistent with theories of sensitivity.
Should we understand sensitivity as a continuous dimension that ranges from low to high or as a category, with some people being highly sensitive and others not?
The study of high sensitivity began with curiosity about the casual use of the term “sensitive” among psychologists. It led to interviews, and based on these, to the 27-item Highly Sensitive Person Scale.
