Purpose: The aim of this study was to investigate the appropriateness of standardized assessments of expressive grammar and vocabulary in a sample of preschool-age dual language learners (DLLs) who use Jamaican Creole (JC) and English. Adult models from the same linguistic community as these children were used to inform culturally and…

Research Findings: The present study investigates both the proximal processes and contextual influences on children's oral language development in preschool. We examine whether teacher language practices vary across activity settings and program type, which teacher language practices predict children's oral language skills, and potential…

Assessing a child's language in the early years is critical to plan for an early intervention and maximize their learning potential. In a unique pan-Arabic approach to language development, we developed a new Arabic assessment tool, usable by parents and Early Years professionals to screen vocabulary in children between 8 months and 30 months…

Purpose: Most educational assessments tend to be constructed in a close-ended format, which is easier to score consistently and more affordable. However, recent work has leveraged computation text methods from the information sciences to make open-ended measurement more effective and reliable for older students. This study asks whether such text…

Background: Late language emergence is a risk indicator for developmental language disorder. Parent-implemented early language intervention programmes (parent programmes) have been shown to have positive effects on children's receptive and expressive language skills. However, long-term effectiveness has rarely been studied. Additionally, little is…

The present study explores the vocabulary development of bilingual children when neither of their languages has a minority language status. With both languages having high relative prestige, it is possible to address the impact of exposure variables: age of onset, length of exposure, and frequency of exposure (FoE) to both languages. Parents of 40…

Investigations of early vocabulary production often employ a single method to measure children's word use. This study examined expressive vocabulary development in children aged 1;0-2;6 years through a combination of picture naming, caregiver report and language sampling. The participants were predominantly exposed to Maltese at home, with…

Nineteen shy, twenty-three middle and twenty-five non-shy junior kindergarten children were assessed at school by an unfamiliar examiner, and at home where their parents administered a parallel form of the expressive and receptive vocabulary tests given at school. A speech sample between the child and parent was also collected at home. Shy…

Assessed long-term predictive validity of the MacArthur Communicative Development Inventories: Words and Sentences (CDI:WS) for children's expressive and receptive vocabulary development. Sixty-one New Zealand children were assessed with a New Zealand version of the CDI, and with the Expressive Vocabulary Test and Peabody Picture Vocabulary…

Exploration of the usefulness of a visual preference technique for assessing word comprehension in infants demonstrated increases in comprehension from 8 to 14 and 14 to 20 months; established longitudinal stability of comprehension from 14 to 20 months; and showed a profound effect of stimulus salience and the lack of sex differences in word…

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.…

Analysis of data from studies investigating the effectiveness of a parent report form for assessing children's early language development showed that the vocabulary checklist had substantial validity, and that it helped parents to provide a valuable overall evaluation of their children's language at 20 months.

Discusses construction of the Hebrew Communicative Development Inventory (HCDI), an adaptation of the MacArthur Communicative Development Inventory (MCDI). The HCDI was administered to a stratified sample of Israeli mothers of 253 toddlers. Results are presented and compared with scores from the MCDI. Results indicate that conclusions concerning…

The distribution of errors in children's responses in four elicitation tests of their color-naming abilities is explored with a view to clarifying states of ignorance. Subjects include 47 Polynesian children ranging in age from 2 to 12 years. The four experiments include a naming task, two identification tasks and a mapping task. Children are…

The collection of papers on language development and African-American children includes: "The Challenges of Conducting Language Research with African American Children" (Holly K. Craig); "Issues in Recruiting African American Participants for Research" (Joyce L. Harris); "Issues in Assessing the Language Abilities of…
