The spontaneous utterances produced by 492 Cantonese-speaking children aged 36 to 60 months in 30-minute toy play contexts were collected. The incidence and percentage of different lexical classes, the ratio of noun and verb types and tokens were calculated. A statistically significant predominance of verb usage was found in the expressive utterances of the children. No similar predominance was...

We investigated whether fine motor and expressive language skills are related in the later-born siblings of children with autism (heightened-risk, HR infants) who are at increased risk for language delays. We observed 34 HR infants longitudinally from 12 to 36 months. We used parent report and standardized observation measures to assess fine motor skill from 12 to 24 months in HR infants (Study...

Two studies on the role of video on vocabulary learning were conducted in kindergarten classrooms wit h substantial numbers of children from low-income and Dual Language Learning (DLL) backgrounds. In the first study (n = 78), the effect of video viewing was compared with the effect of book reading on vocabulary learning. In the second study (n = 89), the effect of repeated viewing of video was...

RDF Schema (RDFS) extends RDF with a schema vocabulary with a predefined semantics. Evaluating queries which involve this vocabulary is challenging, and there is not yet consensus in the Semantic Web community on how to define a query language for RDFS. In this paper, we introduce a language for querying RDFS data. This language is obtained by extending SPARQL with nested regular expressions th...

CONTEMPORARY ISSUES IN COMMUNICATION SCIENCE AND DISORDERS • Volume 28 • 20–29 • Spring 2001 © NSSLHA 1092-5171/01/2801-0020 ABSTRACT: Spoken word recognition was investigated in a group of children aged 3:0 to 7:11 (years:months) to assess the relationship between five measures of language development and spoken word recognition accuracy. Two spoken word recognition tasks, gated words and nois...

Language input is crucial for language acquisition and especially for children's vocabulary size. Bilingual children receive reduced input in each of their languages, compared to monolinguals, and are reported to have smaller vocabularies, at least in one of their languages. Vocabulary acquisition in trilingual children has been largely understudied; only a few case studies have been published ...

Recent research using the looking while listening paradigm has shown that 18-montholds with larger vocabularies look more rapidly to pictures of familiar objects than their peers with smaller vocabularies. The purpose of this study was to extend this work to older children (30 to 60 months) and to include children from both middleand low-socioeconomic status (SES) families. Because the children...

Prior research has indicated that pragmatics is an area of particular weakness for individuals with Williams syndrome (WS). To further address this aspect of the WS social phenotype, we used an individual differences approach to consider both cross-sectional and longitudinal relations among different pragmatic abilities for 14 children with WS, taking into account individual differences in non-...
