Ambridge's proposal cannot account for the most basic observations about phonological patterns in human languages. Outside of the earliest stages of phonological production by toddlers, the phonological systems of speakers/learners exhibit internal behaviours that point to the representation and processing of inter-related units ranging in size…

Word order is one of the earliest aspects of grammar that the child acquires, because her early utterances already respect the basic word order of the target language. However, the question of the nature of early syntactic representations is subject to debate. Approaches inspired by formal syntax assume that the head-complement order,…

Analysis of mothers' pragmatic language use and children's language levels during free play sessions suggested that a mother-driven, direct influence model may be inappropriate for many mother speech-child language development relationships and points to the feasibility of child- and mother-driven explanatory models for indirect relationships.…

Reports a case study of a British 2-year old that shows a stage in syntactic development without a subject agreement protection but with a tense phrase. A sharp contrast in use of verb forms suggests that the child had left the Optional Infinitive stage and entered a transitional stage, where the major development is that the status of the bare…

Adult "redoing" sequences (expansions and repeats) in conversations between adult and child (age 1;6) are analyzed with a conversational analytic approach, and two ways in which redoing sequences are involved in the initiation of repair are explored. It is proposed that a redoing sequence picks up a child's utterance and displays it for some kind…

While children aged 1;10 and 2;1 show only a modest rate of mapping novel nouns onto unfamiliar rather than familiar objects, children aged 1;4 and 1;8 show a high rate. Two studies with young 2-year olds found the noun-mapping preference prevalent, but unless initial choices are strongly reinforced, increase in salience of familiar kinds lures…

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…

This study investigated the earliest manifestations of verb tense and agreement in English-speaking children, using longitudinal data on the language of four children aged 1:6 to 3:5 years, drawn from a child-language database. Analysis focused on one aspect of inflectional phrase (IP), the children's use of the verbs "be" and "do" forms to mark…
