This investigation addresses problems of defining verbal imitation, and suggests solutions by analyzing verbal interactions between two children and their mothers. Children were between 18 and 35 months old, with a mean length of utterance between 1.4 and 4.2 morphemes. Analyses focus upon the uses these children made of maternal models; 10…

Assesses the interrelations among the functional properties of maternal speech, the structural properties of maternal speech, and child language growth for a period of six months for 22 two-year-old children and their mothers. (HOD)

Explores the relations among combinatorial capacities in language, symbolic play, blockbuilding, and nonsemantic action sequences within a sample of 18- to 24-month-old children, as well as assessing the developmental level of a selected subset of concepts. (HOD)

The influence of information level on the production of accuracy of 20 children was examined. Data were children's productions of nouns in sets of utterances referring to triplets of pictures representing noun-verb-noun utterances. (Author/JL)

Presents evidence that the supposed paradox in which infants find abstract patterns in speech-like stimuli whereas even some preschoolers struggle to find abstract syntactic patterns within meaningful language is no paradox. Asserts that all research evidence shows that young children's syntactic constructions become abstract in a piecemeal…

Asserts that the posited paradox between infancy and toddlerhood language was not eliminated by Tomasello and Akhtar's appeal to infants' robust statistical learning abilities. Maintains that scrutiny of their studies supports the resolution that abstracting linguistic form is easy for infants and that toddlers find it difficult to integrate…

A study of two year olds investigated the nature and development of children's early productivity with verb-argument structure and verb morphology. Results indicated that the children showed no signs of productive verb morphology, but they did use newly learned verbs in some creative ways involving nounlike uses and the appending of locatives.…

This paper outlines the degree to which age and verb vocabulary size are predictive of changes in the reported usage of English verbs that are irregular in their past tense form in a sample of more than 1,000 children. (Contains 40 references.) (JL)

This study examines the processes underlying vocabulary acquisition, i.e., how new words are learned, in children with Williams Syndrome, a rare neurodevelopmental disorder. A Williams Syndrome group was compared to groups of normal controls in the range 3-9 years in four different experiments testing for constraints on word learning. (Author/JL)

Comments on the findings of study of maternal input into children's category knowledge in this monograph. Discusses such aspects of maternal input as the child's role in guiding the parent's language, conceptual development, ways of imparting information about category types, parental speech patterns and how they help children learn optimally, and…

Two experiments examined toddlers' noun vocabularies and interpretations of names for solid and non-solid items. Results indicated that one side of the solidity-syntax-category organization mapping was favored. Seventeen- to 33-month olds do not systematically generalize names for solid things by shape similarity until they already know many…

This paper, based on naturalistic data, describes the acquisitional course and use of the articles "a" and "the" in young English-speaking children (18-61 months), with special emphasis on the role of individual variation. A growth modeling approach to the data reveals that children's individual acquisition schedules are similar in trend, but vary…

The phonological rhythm of French is characterized by a tendency to syllabic isochrony within an utterance and a clear final lengthening, whereas the rhythm of English is stress-timed. A study of babbling at a turning period of the child's development has shown that the French child acquires adult phonological rhythm quite early in interactive…

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…

Changes in mothers' strategies for eliciting verbal responses (EVR's) as a function of child age were investigated in this study. Seven mother-child dyads were observed in their homes when the children were 16, 21, 24, 30, and 34 months of age. Mother EVR's were coded according to syntactic form, type of cue for child response, and complexity of…
