Data from 34 children suggest that a range of Italian grammatical morphemes reach the level of mastery by age 3;6-4;0. In the period between 2;6 and 3;0, as use and comprehension of morphemes are being consolidated, homonymy and informativeness seem not to play a role, though number continues to exert an influence. Some form classes of Italian are…

This study of 80 autistic (ages 6-18), mentally handicapped, and normal children found that more autistic subjects used neologisms and idiosyncratic language than age- and language-skill-matched control groups. More autistic children used words inappropriately that were neither phonologically nor conceptually related to intended English words than…

This study tested the hypothesis that children as young as two years use what adults tell them about meaning relations when making inferences about new words. Subjects (n=18) learned two new terms, with instructions to treat one term as superordinate to the other or replace one with the other, and with no instructions. Children used both kinds of…

Examined cross-linguistic similarities and differences in early lexical and grammatical development among English- and Italian-speaking preschoolers. Parents completed surveys on vocabulary size, vocabulary composition, and grammatical complexity. No cross-linguistic differences surfaced in the composition of vocabulary in this age range. There…

The lexical variables of word frequency and neighborhood density were hypothesized to facilitate sound change to varying degrees. Twelve children with functional phonological delays participated in an alternating-treatments experiment to promote sound change. Results indicated word frequency was most facilitative in sound change, whereas dense…

Compared mother', fathers', and siblings' corrective repetitions to children's errors across different settings. Analyses revealed that mothers and fathers provided more corrective repetitions than did siblings. Results are discussed in terms of current negative evidence research. (Author/VWL)

Presents data that challenge the view that the omission of functional categories by children with specific language impairment is a manifestation of the same immaturity characterizing the grammar of young children without impairment. Data include atypically high omissions or even almost total absence of determiners in the speech productions of a…

Evaluates a teaching program called TRAC (Talk, Reasoning, and Computers) that is used for scaffolding children's effective use of language as a tool for reasoning and collaborative activity. Finds that using the TRAC program can increase the amount of exploratory talk used by children working together in the classroom. (CMK)

Examines structural consequences of intensive language contact on simultaneous first language (L1) and second language (L2) child language development in an L2-dominant environment. Based on the assumption that structural processes in language contact are operating at and determined by abstract lexical structure, various structural configurations…

Psychometric properties of the MacArthur Communicative Development Inventory (CDI) were examined. Findings suggested that the CDI reflects the progress of language development within the age range 10 to 27 months. Findings support caution in using results to identify individuals at risk for language deficits, to compare groups with different…

Examined how Hebrew-speaking children acquired Hebrew-derived nominals (HDNs) of two types (action nominals and deverbal nouns). Child and adult native Hebrew speakers were tested on comprehension and production of HDNs. Acquisition of HDNs began at age 8 and was not complete by age 15. Task type, binyan patterns, and morphological regularity all…

Examines how young children describe reversals of action that restore objects to a prior, less-constrained, state. In both English and German, children first rely on the verb "open"; they then use their knowledge of particle pairs. Reentry into a prior state is underlined by uses of "back" and "wieder" and the…

Discusses the need to start second-language learning in the primary grades and the budget constraints impeding implementation of early second-language education. The article advocates using the young children themselves to persuade school administrators and parents to support the teaching of second-language courses in the primary grades. (CK)

Analyzed records of Slovene children's speech from a linguistic point of view and established differences in communication patterns with regard to the children's ages and the type of symbolic play. Found a shift in play from make-believe with regard to objects to roleplay related to social context. The older the child, the more language functions…

Explores the possibility that the early predominance of infinitival forms in children acquiring Dutch as their first language is related to patterns in the language input. Analyzed a corpus of utterances addressed by two Dutch-speaking mothers to their 2- and 3-year-old sons. Root infinitive utterances amounted to 10%, and auxiliary-plus…
