The structure of extraversion in preschool aged children

Theorists have hypothesized that the construct of extraversion is comprised of several factors, including positive mood, reward seeking/sensitivity, and sociability. The structure of extraversion was examined in a sample of preschool aged children who participated in both home and laboratory observations. A model of extraversion that included these three factors fit the data well. Analyses suggested that each of the facets examined are highly related to extraversion and none stands out as the core of the construct.
