Exploratory factor analysis of human infant temperament in the rhesus monkey

The triadic model of human infant temperament, involving Negative Affectivity, Orienting/Regulation, and Surgency/Extraversion factors, was applied to the rhesus neonate using exploratory factor analysis (EFA). Replicating and expanding earlier work in rhesus monkeys, the three-factor solution produced latent constructs comparable to human neonatal temperament.
