As plurilingual/multilingual research advances, factors that contribute to or hinder individual's flexible language use are still underexplored. Questions such as "Why do some people identify as plurilingual and pluricultural while others do not?" and "What factors contribute to high levels of plurilingual and pluricultural…

Measuring language dominance, broadly defined as the relative strength of each of a bilingual's two languages, remains a crucial methodological issue in bilingualism research. While various methods have been proposed, the Bilingual Language Profile (BLP) has been one of the most widely used tools for measuring language dominance. While previous…

The purpose of this paper was to study the effectiveness of language acquisition using speaker instruction and listener instruction and examining the emergence of bidirectional intraverbals using a non-sense language. Current research suggests that speaker type instruction is more effective in aiding untrained relations (Contreras et al., 2020;…

There are several benefits for Dual Language Learners (DLLs) when their home language is integrated into classroom instruction. For example, instruction in students' home language facilitates the learning of the new language more rapidly and supports bilingualism. One way to enhance young children's language learning is to engage families in home…

In this paper, we examine whether a student's language background and other demographic factors have any relationship to their performance on prose questions in math, which we define as questions with open-ended answers containing one or more complete sentences of English. Prose questions stand in contrast to non-prose questions, which are more…

English language students often struggle to acquire and retain academic vocabulary due to limited exposure and insufficient opportunities for meaningful engagement with new words. Explicit, structured vocabulary instruction is essential to acquire word ownership, defined as understanding a word's meaning and using it in various contexts. This…

The English Resultative Construction (ERC) is a satellite-framed structure with no identical equivalent in Spanish. In a series of studies, we analyzed and compared recognition (acceptability judgment task) and comprehension (sentence comprehension task) of three ERC subtypes with the English Depictive Construction (EDC) (which has a Spanish…

The current study contributes to the argument regarding whether L2 learners up to advanced levels make agreement errors on grammatical gender. It reports gender agreement accuracy on a written Grammaticality Judgment Task (GJT) and an Elicited Oral Production Task (PDT) on known nouns assigned the correct gender by participants on a vocabulary…

Purpose: Language sampling is a critical component of language assessments. However, there are many ways to elicit language samples that likely impact the results. The purpose of this study was to examine how different discourse types and elicitation tasks affect various language sampling outcomes. Method: A diverse group of K-3 students (N =…

In bilingual children, more so than in monolingual children, comprehension abilities exceed production abilities. While this receptive-expressive gap in bilinguals has been well documented, little is known about its development. The present study tracked growth in the Spanish and English receptive and expressive vocabularies of 52 bilingual…

Purpose: This study explored approaches for measuring vocabulary among bilingual children with varying levels of proficiency in Spanish and English. Method: One hundred fifteen kindergarten and first-grade Spanish--English-speaking children completed measures of vocabulary and sentence repetition in Spanish and English. Scores were derived from…

Purpose: The finite verb morphology composite (FVMC) is a valid measure for charting children's tense development and for differentiating children with and without language impairment during preschool and early elementary years. However, it is unclear whether FVMC scores vary as a function of language sample elicitation contexts. The current study…

With the increasing prevalence of autism diagnoses globally, the overall aim of this dissertation is to improve our understanding of the linguistic aptitude of autistic individuals. Given that the autism diagnosis is a spectrum, we rely on the Autism Quotient (AQ) test, which measures the quantity of autistic-like traits an individual possesses,…

The Comprehensive Test of Phonological Processing, 2nd Edition (CTOPP-2; Wagner et al., 2013) is commonly used in k-12 public schools to assess basic cognitive processing skills foundational for reading achievement. Psychometric support for its use with dual language learners (DLLs), a group representing over 10% of the school-aged population in…

This study explored the effects of learning activities which encouraged positive crosslinguistic influence from L2 Spanish to L1 English grammar in young learners. The learners (N = 82) were studying Spanish as their compulsory foreign language at an English state primary school in the UK. As part of ten timetabled Spanish classes over a period of…
