This longitudinal study examined growth in the English productive vocabularies of bilingual and monolingual children between ages 24 and 36 months and explored the utility and validity of supplementing parent reports with teacher reports to improve the estimation of children's vocabulary. Low-income, English-speaking and English/Spanish-speaking…

This investigation examined the impact of maternal language and children's gender on bilingual children's vocabulary and emergent literacy development during 2 years in Head Start and kindergarten. Seventy-two mothers and their children who attended English immersion programs participated. Questionnaires administered annually over a 3-year period…

The Macarthur-Bates Communicative Development Inventories (CDI) have been used widely to document early communicative development. The paper reports on a large community sample of 1,447 children recruited from low, middle and high socioeconomic (SES) areas across metropolitan Melbourne, Australia. Regression analyses were conducted to determine…

Purpose: The present investigation examines the time, effort, and resources that evidence-based practice (EBP) requires, and looks at what types of results are obtained. Method: Principles of EBP as outlined by the American Speech-Language-Hearing Association were applied to 3 treatment case studies. Results: The cases took between 3 and 7 hr to…

Parents' object labels can be distinguished by whether the child is already attending to the object (follow-in) or not (lead-in). Lead-in labels have been found to be associated with low vocabulary. The current study examines whether the relation between lead-in labels and child vocabulary is influenced by whether the child's attention is…

Objective: To examine the effects of early maternal and paternal depression on child expressive language at age 24 months and the role that parent-to-child reading may play in this pathway. Participants and methods: The 9-month and 24-month waves from a national prospective study of children and their families, the Early Childhood Longitudinal…

The factors affecting the mastery of the host country's language by the children of immigrants are important in the study of immigration-related issues. This exploratory study analyses the possible link between parental socio-linguistic background factors (parent-child language choice, parental proficiency in L2, educational level, socio-economic…

Parents of children with suspected Childhood Apraxia of Speech (sCAS, n = 20), Specific Language Impairment (SLI, n = 20), and typically developing speech and language skills (TD, n = 20) participated in this study, which aimed to quantify and compare reports of early vocal development. Via a questionnaire, parents reported on their child's early…

Investigation into the relative effectiveness of four input strategies for two-year-olds' (N=56) category evolution found that the most effective strategy involved labelling an object and providing both a physical demonstration and a verbal description of important attributes. (Author/CB)

Relative importance of appearance and potential function in children's object naming was examined. First, 16 children, taught novel names for unfamiliar objects, had to decide whether these applied to items that resembled the training objects in appearance or potential function. Then the name training procedure was revised so that equal emphasis…

Interaction between lexical acquisition and acquisition of initial voiceless stops (VSs) was studied in two normally developing children by acoustically examining token-by-token accuracy of initial VS targets in different lexical items. Tokens representing the emergence of accurate VS production were restricted to certain words, largely old words…

Previous studies show that young monolingual children's ability to "fast map" new word forms is closely associated with both their age and existing vocabulary knowledge. In this study we investigate potential relationships between age, fast mapping skills and existing vocabulary knowledge in both languages of developing bilingual preschool…

Numerous studies show that children's language ability is related to false-belief understanding. However, there is considerable variation in the size of the correlation reported. Using data from 104 studies (N=8,891), this meta-analysis determines the strength of the relation in children under age 7 and examines moderators that may account for the…

Theories of the acquisition of word meaning among children are reviewed and a case study of one child is reported. Three models of how the young child associates words with underlying concepts and conventional meanings are noted. While one model proposes that children initially overextend word meanings, the other two models propose that new words…
