The acquisition of early verbs in French: Assessing the role of conversation and of child-directed speech

This article examines the production of early verbs by two children acquiring French as their first language. The study focuses on the developmental period during which verbs are produced in one form only. Child-directed speech (CDS) and conversational contingencies (CC) occurring around these verbal forms were analysed up to the moment when some verbs are produced in two different forms. Results show that children’s use of a single form per verb can also be found in CDS by adults where the majority of verbs are used in one morphophonological form only. Moreover, the particular form children use for a given verb corresponds to the one adults predominantly use in CDS. At the same time, child-produced verb forms are reinforced in the CC occurring in adult—child exchanges. When trying to separate the role of CCs from that of more general CDS, for both children the study found that for about half of the verbal forms CDS and CC provide the same congruent information. Of the remaining verb types, three-quarters are explained by CC, while fewer then 15 percent are explained by CDS, indicating that CCs are a stronger source of influence than general input. These findings underline the close relationships between patterns of language acquisition, conversational exchanges and CDS. The data suggest a construction process based on specific characteristics of the language children hear, what they can produce and, importantly, the temporally close reinforcing relations between these two that are forged in conversational interactions.
