The Influence Of Sibship Composition On Language Development At Age 2 years in the ELFE birth cohort study

Resumen

Using data from 12,296 children (49.3% female) from the French ELFE birth cohort, we analyzed the effect of various characteristics of the siblings on children’s expressive vocabulary. Children’s vocabulary at age 2 years was negatively associated with the number of older siblings (-.08 SD per additional sibling), and this effect was partly mediated by parental interactions. In an analysis restricted to children with one older sibling, the vocabulary score was negatively correlated with the age gap between the target child and their older sibling. In addition, our results suggest that older siblings might partly compensate for the effect of having foreign-speaking parents. Overall, our results are consistent with the resource dilution model and inconsistent with the confluence model.
