This article investigates the production of the emphatic consonants /?, ?, ?/ by typically developing Jordanian children. Sixty typically developing monolingual Ammani Arabic-speaking children (30 boys and 30 girls) with ages ranging from 2 to 7;11 years were recruited in a production experiment. In the experiment, they were asked to produce 18…

The current study investigated the impact of birth order on vocabulary and social language development in 1338 first-born and 1049 s-born autistic youth (M age = 9.03 years, SD = 3.57; 86.4% male) from the Simons Simplex Collection. Frequentist and Bayesian analyses revealed mixed findings in language development. There were no differences in…

Children growing up in disadvantage are more vulnerable to speech, language, and literacy difficulties, which are important in the acquisition of many different life skills. Despite supported playgroups engaging directly with families living in disadvantage, very few speech and language studies have been delivered within this setting. This study…

Research has shown that interactive book reading in early childhood classrooms contributes to children's language development. High quality interaction during book reading has been shown to be even more beneficial for children's language development, but more research is needed on which interaction practices really work, as there is great…

This study investigated classroom interaction in three novice-level Chinese language classrooms at middle and high schools in the US in the spring of 2021. Due to school responses to the COVID-19 pandemic, the participating teachers had shifted from teaching in a face-to-face, in-person classroom to fully online and partially online, hybrid…

This dissertation provides an in-depth linguistic description and analysis of the discourse in a target domain of digital games, a domain referred to as "single player offline role-playing games." Gaming discourse from this domain is represented by a 4.8-million-word corpus of spoken and written language extracted from the digital files…

Early Expressive language exposure is associated with child language acquisition and advantageous long-term developmental outcomes. The measurement of expressive language in a child's immediate environment is critical to the early identification of children who are at risk of low expressive language exposure, such as children with language delays…

Our research, focusing on critical literacy practices in education, demonstrates the outcome of a teaching scenario applied in 2021 in a primary school e-class learning environment with the aid of distant learning tools. Having taken for granted that: (a) COVID-19 pandemic has initiated important changes regarding our understanding of language…

Purpose: The purpose of this study was to identify and describe latent dual language profiles in a large sample of school-age Spanish-English bilingual children designated as English learners (ELs) by their school district. Method: Data for this study include 847 Spanish-speaking ELs from kindergarten to third grade. Spanish and English narrative…

Autism is often associated with early developmental delays in language and motor skills. However, little is known about the complex dynamic processes that drive the co-development of such early difficulties. The aim of the present study was to model the parallel growth of language and motor skills in a cohort of infants and to explore differences…

In a changing society where the roles of fathers and mothers in caregiving are becoming more equal, the role of the father in early language development has also changed. We aimed to study associations between paternal factors and early vocabulary development in boys and girls. In a longitudinal cohort study, we examined the growth of expressive…

Children facing adversity are at greater risk of experiencing language difficulties than their peers. This study aims to examine the association between specific maternal responsive behaviours at 24 months and language outcomes at the age of 5 years in a cohort of mothers and children facing adversity. Mother-child dyads (n = 138) facing adversity…

We inquired whether introducing variability into a word-learning task would facilitate, inhibit, or have a neutral effect on adults' speech production and language learning. Twenty young adults from the U.S. Midwest with typical development participated. They repeated four novel words 10 times sequentially (blocked practice) and another four novel…

Languages differ regarding the depth, structure, and syntactic domains of recursive structures. Even within a single language, some structures allow infinite self-embedding while others are more restricted. For example, when expressing ownership relation, English allows infinite embedding of the prenominal genitive "-s," whereas the…

Vygotsky's (1993) "Fundamentals of Defectology" is a radical's handbook of deaf and disability studies. Vygotsky's overall research program views disabilities, including deafness, from an integrated biosocial and critical theory standpoint. In two movements, I introduce an "American Annals of the Deaf Special Issue" on…
