This dissertation develops a cognitive model describing when children learn to group distinct sound segments (allophones) into abstract equivalence classes (phonemes). The allophones an individual acquires are arbitrary and determined by their particular input, yet are intricately involved in language cognition once learned. The proposed…

This case report describes a young child with inconsistent phonological disorder (IPD). The child presented with unintelligible speech. She made limited progress on individual speech production goals targeting phonological patterns over 4 years, remaining unintelligible. The child was diagnosed with IPD following an inconsistency assessment and…

Infants show shifting patterns of visual engagement to faces over the first years of life. To explore the adaptive implications of this engagement, we collected eye-tracking measures on cross-sectional samples of 10-25-month-old typically developing toddlers (TD;N = 28) and those with autism spectrum disorder (ASD;N = 54). Concurrent language…

Advances in Natural Language Processing (NLP) over the past decade have largely been driven by the scale of data and computation used to train large neural network-based models. However, these techniques are inapplicable to the vast majority of the world's languages, which lack the vast digitized text datasets available for English and a few other…

This qualitative case study explored an elementary foundations mathematics course and the mathematics vocabulary elementary pre-service teachers (PSTs) encounter at various stages in their preparation as mediated by curriculum, standards, and assessment materials. Guided by the theoretical lens of a constructivism-informed conceptual framework,…

This article shares a case study of a classroom of multicultural and multilingual children in an early childhood center to explore how iPad apps can support young children in learning English as an additional language. Situated in Sydney, Australia, this study found that iPad apps have the potential to promote 4- and 5-year-old children's language…

Explicit instruction in the academic language of disciplines is considered a major component of effective literacy development for adolescents (National Governors Association, 2010) and has become one of the standards in all disciplines. States have mandated that schools adopt teacher evaluation models and professional learning community (PLCs)…

Teachers in Nevada have faced the problem of providing consistent, effective literacy instruction to elementary students, which impacts overall student achievement; only 48.3% of students in Clark County, Nevada were proficient in English Language Arts (ELA) in the 2018-2019 school year. This problem was explored from a case study perspective…

Background: Teaching English as home language (EHL) could be a complicated process in a country like South Africa, where there are eleven official languages operating in a multicultural society. This requires capacitating teachers with appropriate and relevant strategies to strengthen their teaching, especially in the foundation phase. Aim: This…

Purpose: From a psycholinguistic perspective, the quality of the stored word form in the phonological input lexicon, as well as its effective retrieval from the phonological output lexicon, is of great importance in lexical processing. This study aimed at gaining a deeper understanding of (a)typical word form processing in primary school children.…

This mixed two-way experimental, cross-sectional study investigated fast-mapping (FM) of novel nouns and verbs in 63 Persian-speaking toddlers aged 30 months, including 31 late-talking (LT) and 32 typically developing (TD) matched with respect to age and maternal education. Toddlers were classified as LT if they had limited expressive vocabulary…

Conceptualizing numbers as discursive constructs generated in, and for the sake of, communication, we investigated the development of the numerical discourse of Milo, a boy who was 2 years and 8 months old when we first met him and whom we then followed for 18 months. Our analyses of the child's evolving responses to the question "Where is…

With an increasing need for teaching discipline-specific language to second language (L2) learners, language instructors are tasked with a challenging objective to target the vocabulary that is necessary for students to understand and produce discipline-specific discourse. To meet this objective, language corpora and corpus software have been used…

The words in a language or language variety are often rank ordered in lists that are meant to reflect the relative importance of those words to language users and learners of a language. This rank ordering is done on the basis of the relative prevalence of words in a corpus. Lexical prevalence is often operationalized as measures of frequency,…

Teaching English for specific purposes (ESP), such as Medical English, is especially impactful due to high student motivation and immediate real-world application. Medical professionals devote their careers to improving the health and lives of others. With English-language skills, medical professionals can further their own professional…
