Children with language disorders have particular difficulty with verbs, but when this difficulty emerges is unknown. We examined syntactic (transitive, intransitive, ditransitive) and semantic (manner, result) features of two-year-olds' verb vocabularies, contrasting late talkers and typically developing children to look for early differences in…

The growth rate and the composition of expressive lexicon was studied in a sample of 903 infants between the age of 0;8 and 1;4 whose parents completed the Estonian adaptation of the MacArthur-Bates Communicative Development Inventory-Words and Gestures. As expected, older children had on average larger vocabularies compared to younger children.…

How to help babies and young children right from birth to become competent in talking as well as emergent literacy is illustrated by research findings as well as with specific clinical stories. Both kinds of knowledge can serve to galvanize parents and teachers to increase awareness of infant and preschool language development and the crucial role…

We trained forty German-speaking children aged 1;8-2;0 in their comprehension of UNTER [UNDER]. The target word was presented within semantically organized input in the form of a "narrative" to the experimental group and within "unconnected speech" to the control group. We tested children's learning by asking them to…

This longitudinal study examined the predictive validity of the MacArthur Communicative Developmental Inventories-Short Form (CDI-SF), a parent report questionnaire about children's language development (Fenson, Pethick, Renda, Cox, Dale & Reznick, 2000). Data were first gathered from parents on the CDI-SF vocabulary scores for seventy-six…

Offers resolutions to the paradox of infants' ability to abstract patterns over specific items and toddlers' lack of ability to generalize patterns over specific English words/constructions. Argues that contradictions are rooted in differing methodologies and stimuli content. Suggests that the patterns infants extract from linguistic input are not…

Investigated the interface of form and function in the acquisition of negation in Cantonese-speaking children. Data--from the Hong Kong Cantonese Child Language Corpus--were longitudinal spontaneous samples of eight children aged 1.5 to 3.8 years. Main issues in the study were the sequence of emergence of negative markers and the acquisition of 11…

Discusses how single-word usage reflects two stages in child language development. Early words express internal states and share none of the corresponding semantic features of these words in adult language. Later words approximate the use of adult language and share standard semantic features of adult indicative words. (JMF)

Discusses research in semantic processing and narrative discourse by psycholinguists, applied linguists, and speech pathologists. Focuses on children's comprehension of the language of instruction and contrasts normal and disordered comprehension and performance. Presents excerpts from two language evaluations that utilize some recent approaches…

Comparison of language-impaired two- to three-year-olds (N=10) and normal one-year-olds (N=15) matched for expressive language revealed that the language-impaired subjects acquired a greater number of object concepts presented in a no-action condition than the normal children, although language-impaired subjects' extensions of the names to new…

This article on sampling early semantic productions reports a study of 6 children (ages 31-35 months) with specific language impairments. Subjects produced a greater frequency and diversity of multiword utterances in a free-play sampling situation than in a joint action routine sampling situation. (JDD)
