Development of temperament types from infancy to adolescence: Genetic and environmental influences with an economically and racially/ethnically diverse sample.

ABSTRACT: Kagan theorized biologically based temperament types that are present in infancy, stable across development, and essential for understanding individual differences. Despite evidence, temperament research remains focused on a few prominent dimensions of temperament, without adequately addressing covariance among dimensions and temperament types. Using longitudinal twin data, we took a person-centered statistical approach to identify temperament types and examined continuity and change across five developmental periods (N_infancy = 602; N_toddlerhood = 522; N_{early childhood} = 390; N_{late childhood} = 718; Nearly adolescence = 700). We then examined the genetic and environmental etiology of temperament types. Twins were boys
