Bilingualism continues to increase with more than 350 different languages spoken in the United States, and more than 21% of people over the age of five (approximately 66 million people) speaking a language other than English at home (U.S. Census Bureau, 2020). Many bilingual children in the US speak a minority first language (L1) and English as…

Scalar implicatures (SIs) lie at the interface between semantics and pragmatics, and therefore have evoked great interest for language acquisition research. Many acquisition studies show that young children know the literal semantics of scalar items (like "some", "might", "start" and "or") but have…

Codeswitching is a common feature of bilingual language practices, yet its impact on word learning is poorly understood. Critically, processing costs associated with codeswitching may extend to learning. Moreover, verbs tend to be more difficult to learn than nouns, and the challenges of learning verbs could compound with processing costs…

Background: Early in development, caregivers' object labelling contributes to children's word learning. Language development is a bi-directional process, and differences in joint engagement (JE) and language among children with developmental disabilities such as autism spectrum disorder (ASD) may provide caregivers varying contexts and…

Children's understanding of passives of certain mental state predicates appears to lag behind passives of so-called actional predicates, an asymmetry that has posed a major empirical challenge for theories of passive acquisition. This paper argues against the dominant view in the literature that treats the predicate-based asymmetry as…

Young children from low-SES backgrounds are at higher risk for delayed language development, likely due to differences in their home language environment and decreased opportunities for back and forth communicative exchange. Intervention strategies that encourage reciprocal caregiver-child interactions may effectively promote young children's…

Purpose: This study aimed to (a) provide speech-language pathologists and researchers with a play-based procedure to measure the expression of spoken communicative intents by children aged 3 to 4.5 years and (b) present indicators of these children's capacity to produce these intents in this context. Method: A method inspired by TRIAGE (Technique…

This study explored the language experiences of dual language learners (DLL; n = 19) and English monolinguals (EM; n = 13) in preschool classrooms where English is the primary language of instruction and many home languages are present. Using the Language ENvironment Analysis™ system as a primary tool, we quantitatively analysed an average of 34…

Research-supported knowledge about how children develop language is considered foundational for high-quality instruction and as such, measuring and developing teachers' knowledge has been emphasized across the field of early childhood. However, there is a critical gap in understanding how this static knowledge gained through pre-service and…

This longitudinal study investigated how lexical restructuring can stimulate emerging bilingual children's phonological awareness in their first (L1) and second (L2) languages. Sixty-two English (L1) - French (L2) bilingual children (M[subscript age] = 75.7 months, SD = 3.2) were taught new English and French word pairs differing minimally in…

The first stage of combinatorial speech is better described as variable than uniform. Talk of variants obscures two different aspects of language (knowledge and use) and two different aspects of language development -- acquisition of the grammar (competence) and deployment of the grammar in speaking and listening (performance). Null subjects and…

Early linguistic environment has shown an impact on children's later language development, particularly, child directed speech has been associated with providing children with linguistic input from which to look for regularities and patterns, and boosting children to produce utterances beyond their current competence. This article aims to examine…

Children begin to show symptoms of neurodevelopmental disorders early on in their development. Providing early intervention that is culturally responsive to both families and the child receiving the service is vital for the child's growth. The purpose of this study was to qualitatively explore 14 Latin American Spanish-speaking parents' reactions…

Purpose: This study examines the accuracy of Interaction Detection in Early Childhood Settings (IDEAS), a program that automatically transcribes audio files and estimates linguistic units relevant to speech-language therapy, including part-of-speech units that represent features of language complexity, such as adjectives and coordinating…

Research Findings: Early elementary school is a crucial time for the development of executive functions, but less is known about the impact of parent-child narratives on executive function development in children of this age group. This study aims to investigate the influence of parental scaffolding styles in parent-child co-constructed narratives…
