Despite the fact that in most communities interaction occurs between the child and multiple speakers, most previous research on input to children focused on input from mothers. We annotated recordings of Sesotho-learning toddlers living in non-industrial Lesotho in South Africa, and French-learning toddlers living in urban regions in France. We…

Maternal input addressed to children after an early hospitalization (EH) was longitudinally compared to maternal input directed to typically developing children (TD), at 6, 9, 12, 18 and 24 months of age. The data were analyzed with the CHILDES tools for (a) word-tokens (b) word-types (c) Mean Length of Utterances (MLU) and (d) questions in which…

This paper compared the vocabulary size of a group of 250 bilinguals aged 24-36 months acquiring six different language pairs using an analogous tool, and attempted to identify factors that influence vocabulary sizes and ultimately place children at risk for language delay. Each research group used adaptations of the MacArthur-Bates Communicative…

Simultaneous bilingual education of a child is a dynamic process. Construction of linguistic competences undeniably depends on the conditions of the linguistic environment of the child. This education in a monolingual family, requires the practice of parenting tactics to increase the frequency of the language use in minority, during which,…

Using an observational task followed by an experimental task with an Intermodal Preferential Looking Paradigm, we examined the effect of input on children's acquisition of class extension rules by investigating the relationship between the amount of polysemous noun-verb pairs in French-speaking 2-year-olds' input and both their spontaneous…

Many recent generativist models attribute grammatical knowledge to young children on the basis that children's language patterns the same way as the target adult language. It has been proposed that the child acquires this knowledge early on in development by a process of parameter setting. Wexler (1996) presents the "Very Early Parameter Setting…

Explores spontaneous speech samples from children during the period from one word to multiword utterances in interaction with their French-speaking mothers in order to study the appearance and development of functional changes in their use of language. A longitudinal study of four children revealed the beginnings of references to the past and the…
