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 the current dissertation is to map the relationships between first language (L1), writing quality, and syntactic complexity, accuracy, lexical complexity, and fluency (CALF) in second language (L2) writing. CALF are characteristics of language production that have been of significant interest in L2 writing research for the past few…

Teachers' language attitudes play a key role in their decision-making, evaluation, and behaviour in the classroom. This is as true in a monolingual environment as it is in a bilingual or multilingual linguistic situation, but it is fair to assume that the two different linguistic environments are associated with the dominance of different…

In the realm of language proficiency assessments, the domain description inference and the extrapolation inference are key components of a validity argument. Biber et al.'s description of the lexicogrammatical features of the spoken and written registers in the T2K-SWAL corpus has served as support for the TOEFL iBT test's domain description and…

Purpose: Language sample analysis is widely regarded as the gold standard of language assessment. However, the uncertainty regarding the optimal length of sample and the limited availability of developmental language data for nonmainstream languages such as Afrikaans complicate reliable use of the method. The study aimed to provide guidelines on…

This dissertation investigated how a bilingual's experiences can affect how their first language pronunciation can differ from monolingual speakers of their two languages. We used a methodology incorporating quantitative phonetic measurements of voice onset time and vowel formants, grammar and vocabulary tests, and qualitative measures of language…

Aptitude is a hypernym used in training and practice-based contexts to refer to a person's natural or acquired ability to do something. It tends to be an attribute that is 'forward-looking', i.e. referring to a person's probability of achieving success in the future. This paper adopts a retrospective perspective in looking at the 'success…

Previous studies in the acquisition of clitic se in Spanish have focused on the syntactic processes needed to perform detransitivization. However, current approaches on event structure reveal that "se" encodes aspectual information which is crucial for its acquisition. We examine the use, intuition and interpretation of the aspectual…

This study investigated the efficacy of explicit lexical collocation instruction via the Corpus of Contemporary American English (COCA). To improve competence in lexical collocation and writing performance and to examine whether collocational competence and writing performance have a linear interrelation, 16 international English for Academic…

This research project sought to explore the influence of English L2 on Spanish L1 in an environment where the L1 (Spanish) is the dominant language. Participants were recruited through voluntary response sampling at the University of Puerto Rico Secondary School (UHS). They completed a language survey on Google Forms that collected general…

Scholars have argued for the inclusion of different spoken varieties of English in high-stakes listening tests to better represent the global use of English. However, doing so may introduce additional construct-irrelevant variance due to accent familiarity and the shared first language (L1) advantage, which could threaten test fairness. However,…

Translanguaging and trans-semiotizing research has problematized the static view of language and argued that meaning making is a dynamic, material, social, and historical process across multiple timescales in complex eco-social systems. The second author proposed the concept of trans-semiotizing as an alternative lens to study language teaching…

High-stakes testing can be a major hurdle for individuals who know the material well, but have trouble understanding the language of the test. Many people have difficulty understanding test questions when the wording of the question is different from the language variation typically used by the test-taker. This research builds on prior research…

Global efforts for standards-based linguistic assessment increasingly hold that examinees should be tested in the language with which they are most familiar. Yet, language use still occurs differently from its characterization in exams, even as exams are increasingly developed in historically minoritized languages. Drawing from two years of…

Significant variation exists in how native speakers respond to word association tasks and challenges the usage of nativelikeness as a benchmark to gauge second language (L2) performance. However, the influence of word class and trials of elicitation is not sufficiently addressed in previous work. With controlled stimuli from multiple word classes,…
