In this study, it was aimed to determine the words frequently used in Turkish lullabies and to evaluate the contributions of the lullabies to language education and development through the words determined. Qualitative document analysis was used in the study. "Turkish Lullabies" by Demir and Demir (2014) and "Turkish Lullabies from…

Family language policy research often neglects the dynamic nature of FLP over time. Here, we interview second generation members of migrant families for their recollections as heritage language learners and their experiences setting their own FLP towards their children. We use a transdisciplinary oral history/narrative methodology to discern…

This dissertation explores first language (L1) transfer and second language (L2) transfer processes and models, such as the full transfer/full access model (FT/FA), the representational deficit/interpretability hypothesis, and the feature reassembly hypothesis (FRH). The typological proximity model (TPM), the cumulative enhancement model (CEM),…

This dissertation examines reported speech production among undergraduate college students with a history of developmental language disability (DLD) compared to controls with a history of typical language development (TD). 59 people participated across two separate studies. Study 1 involved a reanalysis of previously recorded in-person dyadic…

Languages tend to have three major clause types (declaratives, interrogatives, imperatives), dedicated to three main speech acts (assertions, questions, commands). However, the particular forms that these clause types take differ from language to language, and have to be learned. Previous experimental results suggest that by 18 months old,…

This study analysed whether the assessment of head righting reflex (HRR) in babies immediately after birth can be used in prediction of early child development. In 54 healthy newborns, testing of HRR was conducted on the third day upon birth. The HRR at birth were correlated with balance ability (BA), speech and language development (SLD) and…

This study identified changes in Korean and heritage language proficiencies across five waves (2011-2015) and examined the association between linguistic acculturation trajectories and adjustment (2016) among Korean adolescents with immigrant family backgrounds (N = 1441; 51.21% female; M[subscript age(baseline)] = 9.97). All adolescents were from…

Purpose: We measure typically developing monolingual child Spanish speakers' lexical development with a range of standard expressive and receptive tests. We also measure their comprehension of sentences with the existential quantifier "algunos" "some" to determine their abilities to generate "some, but not all" scalar…

High-quality caregiver-child relationships are critical to healthy development, including the acquisition of language and literacy skills. However, their potential benefits to early mathematical development and its underlying mechanisms have been minimally explored. In view that language and literacy development play prominent roles in…

There is a well-documented link between bilingual language development and the relative amounts of exposure to each language. Less is known about the role of quality indicators of caregiver-child interactions in bilingual homes, including caregiver input diversity, warmth and sensitivity. This longitudinal study examines the relation between…

This study examined the extent to which the quality of teacher-infant interactions varies across play and routine care activities. In addition, the effects of the quantity of adult involvement in the quality of teacher-infant interactions were investigated. Participants were teachers and infants from 90 infant classrooms in Portugal. Classrooms…

Vocabulary development remains an active and robust research area, yet little is known about what students, particularly young students, think during vocabulary learning. A commonly held assumption is that young learners employ few, if any, cognitive and metacognitive strategies when engaged in literacy tasks. Conversely, decades of research…

Fetal hearing experiences shape the linguistic and musical preferences of neonates. From the very first moment after birth, newborns prefer their native language, recognize their mother's voice, and show a greater responsiveness to lullabies presented during pregnancy. Yet, the neural underpinnings of this experience inducing plasticity have…

For much of the history of deaf education, spoken language bilingualism was not considered a viable goal. It was believed that given the challenges of meaningful auditory access, age-appropriate development in even one language would be daunting. However, implementation of universal newborn hearing screening during the early 2000s, along with…

Word reading and word spelling are important processes of literacy acquisition for children. The longitudinal relationship between reading and spelling is still unclear, especially among bilinguals and biscriptals. In the present study, we compared the longitudinal word reading-spelling relationship in L1 (Chinese) and L2 (English), together with…
