The qualitative - case study aimed to unveil the supportive leadership practices of supervisors in the implementation of Early Language, Literacy, and Numeracy (ELLN) in terms of fostering learner-centered pedagogical practices; providing conducive learning environment; ensuring a balanced curriculum; capacity building; fostering multi-cultural…

Framed by family language policy (FLP), in conjunction with the Douglas Fir Group's ecological transdisciplinary framework for second language acquisition, this multiple case study investigates the FLPs of two Hmong-American families in relation to a Hmong-English dual-language program (DLP) where their children are enrolled. Interviews,…

Dual language learners (DLLs) are a growing student population in the United States, especially in early childhood. However, DLL growth is uneven across the United States, and in many classrooms, DLLs will constitute a "language minority" - that is, they will be the sole or one of few students who speak a non-English home language. Given…

Background: Evidence supports the effectiveness of shared book reading for promoting language and literacy development, but it is known that families experiencing vulnerability may have reduced access to books and are less likely to share books regularly at home. Community hubs often provide support to families experiencing vulnerability and may…

What is vision's role in driving early word production? To answer this, we assessed parent-report vocabulary questionnaires administered to congenitally blind children (N = 40, Mean age = 24 months [R: 7-57 months]) and compared the size and contents of their productive vocabulary to those of a large normative sample of sighted children (N =…

In this dissertation, I establish a research program that uses computational modeling as a testbed for theories of phonological learning. This dissertation focuses on a fundamental question: how do children acquire sound patterns from noisy, real-world data, especially in the presence of lexical exceptions that defy regular patterns? For instance,…

Children achieve better long-term language outcomes than adults. However, it remains unclear whether children actually learn language "more quickly" than adults during real-time exposure to input--indicative of true superior language learning abilities--or whether this advantage stems from other factors. To examine this issue, we…

Echolalia, a language phenomenon whereby individuals imitate the speech of others, is commonly used by children and adults with autism. Research into the underlying nature and meanings associated with this repetitive behaviour is characterised by a lack of conceptual definitions and conflicting opinions about the functions of echolalia. A scoping…

Research suggests that elements of the family environment may have significant associations with cognitive and language development outcomes. Less is known, however, about the family environment in peri-urban China, where rates of cognitive and language delay in children aged 0-3 years are as high as 51% and 54%, respectively. Using data collected…

While America is becoming increasingly diverse, educational stakeholders seek programs that address varied language and cultural needs, which is reflected by the growing popularity of dual language immersion (DLI) programs in recent decades. The problem is an extensively persistent academic achievement gap between students with native English and…

Technology has become an integral part of our daily lives, permeating every aspect. One area where technology has shown potential to enhance English as a Foreign Language (EFL) learning is through the use of animated movies. Despite the growing significance of technology in education, research is scarce in this specific area. Therefore, the aim of…

Pointing plays a significant role in communication and language development. However, in spoken languages pointing has been viewed as a non-verbal gesture, whereas in sign languages, pointing is regarded to represent a linguistic unit of language. This study compared the use of pointing between seven bilingual hearing children of deaf parents…

Using behavioral network analysis, the present study aimed to examine the relation between various cognitive-linguistic skills and Chinese character reading in children from preschool to primary school. A cohort of 172 Chinese children (41.3% female; M[subscript age] = 5.74 ± 0.32 years) were followed from the end of kindergarten (T1) to first…

By 12 months of age, infants exhibit behavioral sensitivity to sound symbolism (e.g. sound-shape correspondences) when they hear universally sound symbolic pseudowords (e.g. "bouba," "kiki"). Here, we investigated whether infant's sensitivity to sound-shape correspondences is affected when they hear language-specific sound…

In spoken languages, children acquire locative terms in a cross-linguistically stable order. Terms similar in meaning to in and on emerge earlier than those similar to "front" and "behind," followed by "left" and "right." This order has been attributed to the complexity of the relations expressed by…
