This dissertation outlines three studies investigating linguistically diverse students' (including bilingual and monolingual students) language use and self-efficacy in writing. Bilingual students are those who speak a language other than English, including students with various levels of English proficiency and language experience. The first two…

We examined the narrative abilities of bilingual and monolingual children on the autism spectrum (AS), whether bilinguals presented stronger social and pragmatic language abilities compared to monolinguals, and the link between narrative, social, and pragmatic language abilities. The narrative, social, and pragmatic language skills of school-aged…

Language-specific (i.e. the ideal L2 self) and plurilingual selves are now at the forefront of scholarly inquiry in L2 motivation research. Yet, there is a lack of empirical studies examining how language learners reframe their sense of self as speakers of an L2. This study draws on a questionnaire (N = 162) and on semi-structured interviews (N =…

Due to their experience of managing two languages, it has been suggested that bilinguals could receive more practice in the domain of working memory (WM) leading to a WM bilingual advantage. Although some studies have shown that bilinguals can outperform monolinguals in WM tasks, the studies investigating WM capacity in bilinguals provide…

A multilingual experience can be considered a significant asset. However, since the earliest studies in the field, research has reported mixed results regarding potential advantages such as increased cognitive ability and metalinguistic awareness. Moreover, studies investigating the influence of bilingualism/multilingualism on the acquisition of…

Purpose: Both monolingual and bilingual children use learning constraints and heuristics to acquire new words from their environment. Overall, fast mapping abilities seem to be similar in both populations, but monolinguals rely more than bilinguals on the mutual exclusivity strategy. Our study probes the robustness of these results in a large…

This study investigates the use of overt and null subjects in Bulgarian in child heritage speakers with L2 German. The alternation of overt and null pronominal subjects in null-subject languages like Bulgarian depends on grammatical and discourse conditions and contrasts with German. Oral narratives were elicited in Bulgarian, comparing the…

Adults, preschool children, and infants gesture more with their right hand than with their left hand. Since gestures and speech are related in production, it is possible that this right-hand preference reflects left-hemisphere lateralization for gestures and speech. The primary purpose of the present study was to test if children between the ages…

We compared two tools that have been used to capture the linguistic heterogeneity and achievement of students in England: the exposure-based distinction between English as an additional language (EAL) and monolingual learners, and the 2017--2018 five level teacher rating of proficiency in English (from "New to English" to…

Using the Early Childhood Longitudinal Study Kindergarten Cohort (2010-2011), this study is the first to investigate predictors of kindergarten science achievement and growth across elementary school--English language proficiency (ELP), executive functioning, math and reading achievement, parent-engaged science and math activities, and classroom…

Since the earliest studies on multilingual advantages, it has proved difficult to disentangle language development from general cognition. It remains unclear whether language interdependence is an independent variable or whether observable effects are mediated by cognitive ability. Measurable effects of one language on another typically go hand in…

As the most commonly established and attested language contact phenomenon, loanwords, also known as lexical borrowings, may undergo transformations when borrowed from the source language (SL) to the borrowing language (BL). Previous studies have separately illustrated the role of perception and phonology in the borrowing process. However, the…

This study investigates the cross-linguistic transfer of literacy skills in Spanish-English, Chinese-English bilingual, and English monolingual children (N = 283, 5-10 years). Research question 1 examines English literacy and asks how phonological and morpho-semantic skills contribute to word reading as a function of children's language…

A growing body of research suggests that children's understanding of mathematical language is critical for their mathematical abilities. Most of this work has been restricted to single language learners (i.e., SLLs), and used dual language learners (i.e., DLLs) as an exclusion criterion, raising questions about the generalizability of these…

In Australian higher education, there is a tension between international students' English language proficiency (ELP) seen as inadequate, thus prompting the need for firm gatekeeping for quality control, and on the other hand, the financial dependence on international student revenues, and therefore, striving to attract international applicants.…
