This article evaluates the "Frames, then Content" hypothesis for speech acquisition, which sees babbling as a direct result of producing syllabic "frames" by rhythmic mandibular oscillation with little of the "content" seen under mandible-independent control. Analysis of 6,659 utterances of 6 normally developing…

Examined whether the use of superordinate terms in 206 children's definitions is predictable by relevance theory. Children (ages 5-10) gave definitions for 16 basic-level words and 4 superordinate words from natural kind and artifact semantic domains. Superordinate terms were used more frequently when they supported more inferences. Findings…

Examined the representation of phrase structure in early child German through the investigation of longitudinal data from seven German-speaking toddlers with respect to verb placement, verb inflection, negation, /wh/ pronouns, and complementizers. It is argued that children construct phrase-structure trees in a gradual fashion, on the basis of…

Two studies are described that investigated preschool children's sensitivity to relative clauses as barriers to the movement of "wh" questions. A cross-sectional study and a longitudinal study conducted over the course of one year found that young children refused to extract "wh" questions from the ungrammatical site inside a…

Vocabulary development of three children, aged 1;6 to 1;8, who had not yet begun to evidence a vocabulary spurt was followed to determine if these children would eventually have a vocabulary spurt. Results of the study are discussed in the context of the argument that a substantial proportion of children never evidence a vocabulary spurt. (JL)

This commentary responds to an article on using directives in early language intervention. It stresses that interventions that tap into the child's focus of attention optimize learning opportunities. When goals are child-centered and are linked to what the child is involved in learning, interventions will be enhanced. (SW)

Reviews "The Transition from Infancy to Language: Acquiring the Power of Expression" (L. Bloom). Underscores that Bloom's account of word learning represents an ethnographic, theoretic, and research approach that explores development by starting with the child, and looks at the many behaviors of the child and views these in relation to…

Uses longitudinal data on language acquisition to examine children's language and sense of self and others. Referential analysis of children's discourse found that children do locate self and other in a spatio-temporal realm. Form-function analysis found that children's discourse about self was more varied in form and in semantic and pragmatic…

The possibility that perceptual predispositions may assist young language learners in the initial identification of words in speech was investigated in a corpus of early words. Results suggest that syllables that are stressed or final in adult speech are particularly salient to young children and likely to be extracted and included in first…

The validity of mean length of utterance (MLU) and a measure of syntactic complexity were tested against the language assessment, remediation, and screening procedure on spontaneous speech samples from 87 children, concluding that MLU is a valid measure of clausal complexity up to 4:5 and that the measure of syntactic complexity is more valid at…

Mental terms in mothers' and their childrens' speech at two and three years were studied to examine relationships between maternal and child use. Nineteen mother and child dyads were videotaped for 1 hour on each of 2 days when children were 2;0 and again for 2 1-hour sessions on separate days when they were 3;0. Mental terms were noted. (JL)

This study examined age differences in the extent to which children infer and use a speaker's interpersonal goal to understand speech acts and to examine age differences in the extent to which children select responses that carry implications appropriate to the speaker's interpersonal goal.

A comparison of the performance of age- and intelligence-matched bilingual (n=46) and monolingual (n=38) six- and seven-year olds on the Illinois Test of Psycholinguistic Abilities indicated that the bilinguals had significantly inferior performance in tests of the visual-motor channel, analogous auditory-vocal tests, and representative level. (18…

Found dissociations between regular and irregular inflectional processes in the formation of English past tenses, German noun plurals, and German participles. Children's inflectional errors include using regular patterns for irregular forms. Some linguistic processes, such as forming compound words, are sensitive to the distinction between regular…

Provides a contemporary Government-and-Binding reinterpretation and evaluation of Klima and Bellugi's 1966 work on the acquisition of interrogatives. It is argued that wh-questions in Child English involve a wh-pronoun positioned in the head complementizer position within the Complementizer Phrase (CP) and that children learn that wh-questions…
