Descriptive grammars based on sets of rewrite rules were constructed to summarize the structure and organization of 120 entries in a second grade student's journal of class news. These rules illuminated the relationship between experience, abstraction, and generation of structure, and the use of structure to express complex thoughts. (PMJ)

Investigates the case of a 7-year-old boy with severe word-finding difficulties. The study used a series of theoretically motivated questions as a framework for psycholinguistic investigation to determine the cause of his difficulties. Findings indicated pervasive deficits in phonological processing, deficits interpreted as a developmental…

Examined whether the characteristics in perception of speech sounds found in preverbal hearing infants might extend to the perception of signed language in infants with congenital deafness. Seventeen Japanese mother-infant dyads participated in the study. Found that infants with deafness showed greater attentional and affective responsiveness to…

Examines the CDI-WORDS Short Form vocabulary checklist as an index of language production. The study focuses on the associations between this short form and directly observed measures of lexical production; the associations between short-form checklists administered at different ages; the predictive associations between short form scores and…

Examined the strength of the association between language exposure estimates and vocabulary learning for simultaneous bilingual infants with differing patterns of exposure to the languages being learned. Findings revealed that the correlation was strong, even for children whose language environments changed by more than 20% between observations.…

A validation study of five checklists for assessing two-year-olds' word production revealed that the lists produced comparable mean production scores, reflected age differences, and preserved individual differences in total production and in production of linguistic categories such as nouns, verbs, open class items, and closed class items.…

A study evaluated how well autistic and non-autistic Japanese primary children (N=35) were able to describe the events in a five-frame cartoon. Results are discussed in terms of cognitive ability and linguistic skills. Discussion focuses on how to help autistic individuals improve their language once they have acquired its rudiments. (DJD)

A microgenetic approach to studying grammatical morpheme learning uses longitudinal data from two children learning English in different ways. Eight general attributes of morphological systems are proposed that will promote or inhibit the emergence of filler syllables during development. (Contains 86 references.) (Author/LB)

The effects of intonation morphemes on the processing of simple reversible sentences containing a dislocated element were studied using synthetic speech stimuli. Both child and adult subjects processed the sentences better when they retained standard subject-verb-object order, suggesting that the morphemes serve as processing instructions.…

Addresses recent advances in research and theory that relate to language shift in early childhood, cognitive, and academic consequences of bilingualism and second-language learning, and theoretical models for conceptualizing the development of bilingualism and second-language learning. Contains annotated bibliography. (47 references) (LET)

A study of subject-verb agreement in 3-year-old speakers of Brazilian Portuguese found an overall low error rate, but with important contrasts in both frequency of production of different verb inflections and rate of agreement errors associated with them, suggesting subject-verb agreement is acquired piecemeal and the learning of particular verb…

A study investigated the extent to which the nature of verb input accounts for the order in which children acquire verbs. Subjects were 57 mothers and their Stage I children. Results suggest that the effect of syntactic diversity in input supports the "syntactic bootstrapping" account of how children use structural information to learn new verbs'…

Proposes an alternative account of the child's learning of nouns and adjectives that relies on properties of the semantic categories to be learned and of the word-learning task itself. In five experiments, a simple connectionist network was trained to label input objects in particular contexts; the network learned categories resembling nouns…

This study provides an account of the distributional information and the production rates in a particularly rich corpus of German child and adult language. Three structural domains are analysed: the parts-of-speech distribution for a coded corpus of circa one million words as well as the internal constituency of 300,000 noun phrases and almost…

Three studies investigated how 24-month-olds and adults resolve temporary ambiguity in fluent speech when encountering prenominal adjectives potentially interpretable as nouns. Children were tested in a looking-while-listening procedure to monitor the time course of speech processing. In Experiment 1, the familiar and unfamiliar adjectives…
