| summary | We investigated the role of socially contingent interactions between infants and their parents in shaping infants’ language development. We hypothesized that infants who experience more socially contingent interactions would have larger vocabularies than infants who experience fewer such interactions. This hypothesis was motivated by our theoretical proposal that socially contingent interactions reveal the communicative and referential nature of words and qualitatively change their informational value for infants (Luchkina & Xu, 2022). We tested our hypothesis by annotating longitudinal video corpus of naturalistic parent-infant interactions when infants were 9 and 12 months to predict their vocabulary size and 12 and 18 months respectively. Our results show that infants’ experience with social contingency significantly predicts infants’ vocabulary and these predictive relations are separable from the effects of language input (types, tokens, MLU) and from the effects of infants’ attention to language input within socially contingent interactions. |
