Genetic Factors in the Ontogeny of Spoken Language: Evidence from Monozygotic and Dizygotic Twins.
Locke, John L.; Mather, Patricia L.
Journal of Child Language, v16 n3 p553-59 Oct 1989
Analysis of speech samples from four-year-old monozygotic and dizygotic twins revealed that the monozygotic twins were significantly more likely to misproduce the same sound on an articulation test than were dizygotic twins. The dizygotic twins were no more likely to share errors than were children who were both genetically and environmentally unrelated. (20 references) (Author/CB)
