This review describes a computational approach for modeling the development of speech motor control in infants. We address the development of two levels of control: articulation of individual speech sounds (defined here as phonemes, syllables, or words for which there is an optimized motor program) and production of sound sequences such as phrases…

Many sentences of adult English are analytic constructions, namely clauses with a matrix verb complemented by a dependent predicate that does not have an expressed syntactic subject. Examples are subject and object control, raising to subject or object, periphrastic tense, aspect and modality, copular predication and "do"-support. In…

We report three studies (one corpus, two experimental) that investigated the acquisition of relative clauses (RCs) in Finnish-speaking children. Study 1 found that Finnish children's naturalistic exposure to RCs predominantly consists of non-subject relatives (i.e. oblique, object) which typically have inanimate head nouns. Study 2 tested…

Children with pre/perinatal unilateral brain lesions (PL) show remarkable plasticity for language development. Is this plasticity characterized by the same developmental trajectory that characterizes typically developing (TD) children, with gesture leading the way into speech? We explored this question, comparing eleven children with PL -- matched…

This study investigates three- to five-year-old children's interpretation of disjunction in sentences like "The dog reached the finish line before the turtle or the bunny". English disjunction has a conjunctive interpretation in such sentences ("The dog reached the finish line before the turtle and before the bunny"). This interpretation conforms…

Recent evidence from adult pronoun comprehension suggests that semantic factors such as verb transitivity affect referent salience and thereby anaphora resolution. We tested whether the same semantic factors influence pronoun comprehension in young children. In a visual world study, 3-year-olds heard stories that began with a sentence containing…

This dissertation studies the acquisition of verb argument structure in the basilectal subvariety of Jakarta Indonesian (henceforth, bJI). There are two characteristics of bJI that potentially affect the acquisition of verb argument structure. First, bJI sentences can surface not only in the full frame but also in truncated frames. Second, the…

English-speaking children make pronoun case errors producing utterances where accusative pronouns are used in nominative contexts ("me do it"). We investigate whether complex utterances in the input ("Let me do it") might explain the origin of these errors. Longitudinal naturalistic data from seventeen English-speaking two- to four-year-olds was…

This paper investigates the development of relative clauses in the speech of one German-speaking child aged 2 ; 0 to 5 ; 0. The earliest relative clauses we found in the data occur in topicalization constructions that are only a little different from simple sentences: they contain a single proposition, express the actor prior to other…

This article investigates the acquisition of the focus particle "auch" "also" by German-learning children. We report data from spontaneous and elicited production of utterances with the focus particle "auch" by 1- to 4-year-olds complementing earlier findings of a delayed production of the unaccented "auch" compared to the accented one. But in…

Previous research suggests that children's behavior with respect to the interpretation of indefinite objects in negative sentences may differ depending on the target language: whereas young English-speaking children tend to select a surface scope interpretation (e.g., Musolino (1998)), young Dutch-speaking children consistently prefer an inverse…

An investigation of children's ability to convey and respond to requests for action was based on the spontaneous speech of 36 dyads of nursery school children (3;6--5;7). Examinations of the contexts of direct requests indicated that speaker and addressee shared an understanding of the interpersonal meaning factors relevant to requesting.…

Two experiments examined the responses of 19-34 month old children to sentences susceptible to more than one interpretation. Results indicate that young children interpret and respond to language in terms of an action-based strategy and that even young children engage in a continuous, context-sensitive process of interpretation. (Author/JAC)

The effects of speech rate, intonation, and sentence length on children's ability to imitate sentences were examined. Results indicate that adult speech is more readily imitated by children when intonation is normal, sentences are short, and speech rate is close to that of the child. (Author/AM)

According to the theory of Universal Grammar, the primary linguistic data guides children through an innately specified space of hypotheses. On this view, similarities between child-English and adult-German are as unsurprising as similarities between cousins who have never met. By contrast, experience-based approaches to language acquisition…
