Language Difference between Twins and Singletons - Biological, Environmental, or Both?
Conway, Dorice; Lytton, Hugh
This data compared language complexity measures, birth information, and family data for twins and singletons of the same sex, age, and socio-economic status. The subjects were four pairs of male twins, four pairs of female twins, four pairs of opposite sex twins, and 24 singletons, 32-33 months of age. Samples of each child's spontaneous utterances were obtained on a two-hour tape recording made in the home setting and an accompanying shorthand record of ongoing action. At the same time measures of articulation and vocabulary comprehension were obtained, a Sentence Initiation Task was administered, and a parent interview form was completed. Birth information was obtained through hospital records. Significant differences between the two groups were found on the language measures, with the twins scoring lower. Rate measures (overall rate of utterance and rate of utterance to mother) were the major source of difference. No significant group differences were found on the phrase-complexity measure. Twin-singleton differences were found on all of the biological measures. It was concluded that the language development of twins may be handicapped by a biological factor of paranatal or prenatal stress and by too much sibling interaction and too little adult interaction in the acquisition of the basic semantic ideas required in advance of expression.
