The work of Harvard Professor of psychology Jerome Kagan was responsible for identifying the behavioural genetics of 'temperament'. Temperament is a trait that starts in infancy and tends to be stable over the course of ones life.

An individual's reactance levels may affect a number of important factors from sociability to stress susceptibility.
