Background: Previous studies have explored the size and word type composition (nouns, predicates, etc.) of expressive vocabularies of preschool children with Down syndrome, both spoken and signed. Separately, overall preferences for modality of expression have also been explored. Aims: To extend previous findings by describing the relationships…

The present study aimed at investigating the contextual stability, the contextual continuity and the concurrent associations between maternal measures (general language, communicative functions and mind-mindedness) and child measures (total number of word types and tokens) in two different contexts, free-play and mealtime. To this purpose, the…

Sometime before their second birthday, many children have a period of rapid expressive vocabulary growth called the vocabulary spurt. Theories of the underlying mechanisms differ: Accumulator models emphasize the accumulation of experience with words over time to yield a spurtlike pattern, while cognitive models attribute the spurt to cognitive…

The purpose of this dissertation is to answer the following question that falls in the intersection of philosophy of language and epistemology: is there any distinctive kind of knowledge that one might possess, merely in virtue of being a native, competent speaker of a certain natural language? When this is expressed as a question specifically…

An understanding of cross-cultural differences in narratives, particularly in children from culturally and linguistically diverse backgrounds, can help clinicians and other professionals distinguish narrative differences from impaired narratives. This study describes similarities and differences in micro-and-macrostructural components in the…

Background and aims: Autism has long been characterized by a range of spoken language features, including, for instance: the tendency to repeat words and phrases, the use of invented words, and "pedantic" language. These observations have been the source of considerable disagreement in both the theoretical and applied realms. Despite…

This study investigates the acquisition and maintenance of periphrastic and se-passives in second language (L2), heritage (HS), and (Spanish-dominant) native Spanish speakers (NS) by addressing: (i) How accessible are Spanish periphrastic passives (which also exist in English) and se-passives (unique to Spanish) for L2ers and HSs in production?…

Early developmental skills, such as attention, language, and fine motor abilities, can be assessed in preschool to predict later achievement, particularly in reading. Connecticut Documentation & Observation for Teaching System (CT DOTS) is a holistic measure used to track the skill development of preschoolers who attend preschool programs…

Minimal expressions are at the heart of interaction: Interjections like "Huh?" and "Mhm" keep conversations flowing by establishing and reinforcing intersubjectivity among interlocutors. Crosslinguistic research has identified that similar interactional pressures can yield structurally similar words (e.g., to initiate repair…

Purpose: This study compares the home language environments of children with (a suspicion of) developmental language disorder (DLD) with that of children with typical development (TD). It does so by adopting new technology that automatically provides metrics about children's language environment (Language ENvironment Analysis [LENA]). In addition,…

This research focuses on the use of parental support messages for children and what these messages mean. Messages of support are a form of positive communication to encourage children to become better individuals. This research used the qualitative method. In answering the formulation problem, speech act theory was used by Yule (2006) which was…

Performing a stay in a country where the L2 is the official language can provide the perfect immersion for L2 development (traditional study abroad). In the case of English learners, internationalization and the role of English as a lingua franca make it unnecessary to perform the stay in an English-speaking country. Hence, an increasing number of…

This study followed the development of Hong Kong Sign Language (HKSL) proficiency in 31 deaf bimodal bilingual children (kindergarten through Primary 6) over two years. The Hong Kong Sign Language Elicitation Tool (HKSL-ET) was used at three time points to elicit the production of agreement, classifier, modal, negation, and wh-question structures.…

Writing is an essential element of literacy development, and language plays a central role in the composing process, including developing, organizing, and refining ideas. Language and writing are interconnected, making it paramount for educators to attend to the development of deaf students' language skills. In this quasi-experimental study, we…

Science learning is important for the well-being of individuals and society. Acquiring the knowledge necessary for success in science is not easy because science involves relational thinking, or the ability to abstract and generalize from similarities between concepts. Using relational words, or shared linguistic labels that identify commonalities…
