Physical Aggression and Expressive Vocabulary in 19-Month-Old Twins.
Dionne, Ginette; Tremblay, Richard; Boivin, Michel; Laplante, David; Perusse, Daniel
Developmental Psychology, v39 n2 p261-73 Mar 2003
Used a genetic design to investigate association between physical aggression and language development in 19-month-old twins. Found a modest but significant correlation between aggression and expressive vocabulary. Substantial heritability was found for physical aggression. Quantitative genetic modeling suggested that the correlation could not be explained by shared etiologies. Phenotype-to-phenotype models indicated that the covariation could be accounted for by a significant phenotypic path from expressive vocabulary to physical aggression. (Author/KB)
