The United States government is perennially in need of employees with proficiency in critical foreign languages to communicate with foreign counterparts and maintain relationships worldwide. In order to fulfill this need, the government devotes significant resources training federal employees to advanced levels of language proficiency through…

Background: Oral language competence provides children with an essential foundation for academic achievement and emotional well-being, yet many children enter school with delayed language and those living in economically disadvantaged areas are at disproportionate risk of experiencing language difficulties. A tiered system, offering high-quality…

We report two studies that investigated the continuity and stability of maternal mind-mindedness (MM) across different times, contexts, and relationships, and also examined child communicative development in the second year of life. Three main findings emerged. First, the percentages of appropriate mind-related comments (AMRC) decreased between 16…

Research on the acquisition of American Sign Language (ASL) by deaf autistic children has documented similarities to the linguistic profile of hearing children on the autism spectrum and has identified sign-specific phenomena that could serve as clinical markers of autism in the deaf population. However, the acquisition of a signed language by…

This dissertation investigates the actual versus perceived knowledge of oral language development strategies among early years teachers in international schools. Employing Prestwich's (2012) "Teacher's Knowledge of Oral Language Development" (TKOLD) survey, it assesses teachers' knowledge in critical areas such as promoting extended…

The study examined 37 language samples of 37 Spanish-English kindergartners and first graders from a larger sample of the Multitudes Project in California. The focus was on investigating how these young English language learners produced narratives in English, what language elements they included, and whether these elements correlated or related…

The present paper evaluates the processes of reading acquisition in Latin from the component-skills approach and discusses how advances in reading in modern foreign languages could be adapted to the specific needs of Latin as a historical language. Compared to the holistic and socially embedded approaches to modern foreign language acquisition,…

Recent advances in mobile technologies have prompted their investigation as tools for language learning. Mobile-assisted language learning (MALL) offers the advantage of flexible language support, enabling learners to choose when and where they learn and the methods that suit them. The constant connectivity of modern mobile phones allows learners…

This dissertation investigates the interaction of developing extralinguistic cognitive systems with early language learning and processing through the case study of verb argument structure. The interaction of these systems with the linguistic system underpins fundamental theories of language learning and use: language does not exist in isolation.…

In early childhood, teacher-child conversations play a crucial role in fostering language learning, particularly vocabulary development. This research examines the mediating role of extended-child-talk between conversation-facilitating (CF) strategies and vocabulary learning in prekindergarten classrooms. Thirty-four teachers' book reading and…

During acquisition, children must learn both the meanings of words and how to interpret them in context. For example, children must learn the logical semantics of the scalar quantifier "some" and its pragmatically enriched meaning: 'some but not all'. Some studies have shown that 'scalar implicature' -- that "some" implies…

Purpose: This retrospective study aimed to amass large data sets to enable statistical comparisons of communication outcomes for infants receiving cochlear implants (CIs) before 9 months of age compared to groups who received their first CI between 9 months and 3.5 years of age. Method: Speech perception scores and experienced clinicians'…

Children acquire language embedded within the rich social context of interaction. This paper reports on a longitudinal study investigating the developmental relationship between conversational turn-taking and vocabulary growth in English-acquiring children (N = 122) followed between 9 and 24 months. Daylong audio recordings obtained every 3 months…

Many studies suggest that detecting statistical regularities in linguistic input plays a key role in language acquisition. Although statistical learning is not necessarily implicit in nature, it is often defined as learning that happens without awareness. This article investigates whether statistical learning in young children is indeed implicit,…

This research revealed that the frequency of reported parent-infant singing interactions predicted 6-month-old infants' performance in laboratory music experiments and mediated their language development in the second year. At 6 months, infants (n = 36) were tested using a preferential listening procedure assessing their sustained attention to…
