Genetic and Environmental Covariation between Verbal and Nonverbal Cognitive Development in Infancy.
Price, Thomas S.; Eley, Thalia C.; Dale, Philip S.; Stevenson, Jim; Plomin, Robert
Child Development, v71 n4 p948-59 Jul-Aug 2000
Examined infant verbal and nonverbal cognitive development for 1,937 pairs of same-sex 2-year-old twins. Found that verbal and nonverbal development correlated .42. Genetic factors were responsible for less than half of this phenotypic correlation. The genetic correlation between verbal and nonverbal abilities was only .30, suggesting that genetic effects on verbal and nonverbal abilities are largely independent in infancy. (Author/KB)
