Purpose: This study examined the effect of phonological overlap on English and Spanish expressive vocabulary accuracy as measured by the bilingual Expressive One-Word Picture Vocabulary Test--Fourth Edition (EOWPVT-IV). We hypothesized that if languages interact during an expressive vocabulary task, then higher phonological overlap will predict…

This study investigated responsive and directive speech from 60 Finnish mothers to their 2-year-old children, as well as correlations with concurrent and later vocabulary. Possible gender differences with regard to both maternal speech and children's vocabulary skills were considered. There were no gender differences in maternal utterance…

Purpose: Cognates, words in two languages that share form and meaning, can be used to support vocabulary development in bilingual children. Typically developing bilinguals have shown better performance on cognates versus noncognates. Of key interest is whether bilinguals with developmental language disorder (DLD) also show a cognate effect and, if…

This study investigated the relationship among home language use, parents' beliefs about dual language development, and Spanish-speaking children's vocabulary knowledge. Parents (n = 162) completed a questionnaire about their home language use and beliefs about dual language development, and elementary-age children (N = 190) -- Kindergarten…

This study documented the standardized tests and informal assessment techniques that school-based speech-language pathologists (SLPs) reported as most helpful for identifying vocabulary deficits and for monitoring progress. Speech-language pathologists (N = 142) working in U.S. public school settings completed an online survey that included…

Vocabulary knowledge is essential for successful language learning. However, little is known about young learners' vocabulary learning in a Thai EFL context and the teaching methods that facilitate vocabulary learning. The current study examined whether songs and total physical response (TPR) can facilitate preschoolers' vocabulary acquisition in…

We examined how educating paraprofessionals in preschool classrooms on dialogic reading (DR) affected their storybook reading and effects on children's single word vocabulary. Through a single-case multiple-probe across participants design including four paraprofessionals and eight preschool children, we identified a functional relation between…

The importance of early vocabulary development to later reading comprehension has been well-established. However, there have been a number of criticisms that the assessments typically used to measure oral vocabulary knowledge do not adequately capture the complexity of this construct. This conceptual review works towards a more robust theoretical…

The purpose of this study is to examine the bidirectional relationship between children's language development and challenging behaviors as well as the moderating roles of gender and race/ethnicity. We conducted a number of structural equation modeling analyses with a national representative sample (N = 2,462) of Head Start children from the 2014…

This study examines the influence of a parent workshop intervention on vocabulary acquisition of at-risk preschool children during parent-child shared storybook reading. Sixty-nine parents were randomly assigned to either treatment or control group. In the treatment condition, parents were taught to implement elaborated vocabulary instruction…

The robust relation between maternal education and child language that is observed in monolingual populations has not been reliably replicated among bilingual children from immigrant families in the United States. We hypothesized that a variable that operates in immigrant populations--the language in which mothers achieved their highest level of…

Research has investigated how lexical-semantic and participant factors impact word learning in young children and adults. However, limited information pertaining to expressive vocabulary development exists for school-aged bilinguals--particularly those with developmental language disorder (DLD). Cross-linguistic differences in the semantic…

This study investigated whether listening comprehension played a mediator role between vocabulary and reading comprehension. 127 Mandarin-speaking children were longitudinally assessed at 6;4, 6;10, 7;4, and 7;10. Data were collected in four batteries of tests implemented at the beginning of first grade (T[subscript 1]); at mid-first grade…

Background: The educational context in South Africa does not always support the development of bilingualism to enable the cognitive and social advantages of dual language proficiency. The emphasis on English as the language of instruction overlooks bilingual competence. This study attempts to show that by considering conceptual vocabulary,…

Purpose: This study investigates the effects of an integrated oral language and listening comprehension intervention for early elementary students with ASD. Methods: Students (n = 43) were randomly assigned to intervention or control comparison conditions, with intervention students receiving instruction in small groups of 3 or 4. Groups were led…
