This dissertation investigates language-specific acoustic and aerodynamic phenomena in language contact situations. Whereas most work on second language and bilingual phonology has focused on individual consonants and vowels, this project examines patterns of coarticulation in the two languages of Spanish-English and French-English bilingual…

This study aims to investigate ChatGPT's ability to comprehend input from nonnative speakers, specifically those learning English as a second language, with Japanese speakers serving as the model population. The experiment examines how ChatGPT evaluates the difficulty levels of the Test of English for International Communication (TOEIC), which is…

Based on writing produced by second language learners at different proficiency levels (CEFR A1 to C1), we adopted a usage-based approach (Ellis, Römer, & O'Donnell, 2016; Tyler & Ortega, 2018) to investigate how German and Spanish learner knowledge of 19 English verb-argument constructions (VACs; e.g., "V with n," illustrated by…

The present study aimed to profile the developmental patterns of discourse in second language (L2) writings among different first language (L1) groups. Applying the list of metadiscourse markers proposed by Ken Hyland to learner language, this study investigates variation of metadiscourse across proficiency levels, as well as across L1…

This study examined how students of English as a foreign language (EFL) with different first language (L1) backgrounds use interactional metadiscourse markers in argumentative writing. Specifically, to explore unique patterns of metadiscourse features that reflect context and development, the essays written by Chinese, Japanese, and Korean EFL…

This article shows that first language (L1) transfer may not be effectively maintained in the interlanguage due to confounding factors in the second language (L2). When two factors, "A" and "B," are correlated in the L2, second language learners may only acquire "B," even if "A" is present in the L1.…

Two experimental paradigms, a picture-naming task and a Stroop interference task, were employed to address the structure of the multilingual mental lexicon; more specifically, the process of multilingual non-selective lexical access. German-English-French speakers named objects in their native and most dominant language in a task that included a…

The great importance of textbooks in the English language in the academic, pedagogic, and scientific world is uncontested. Acquiring holistic knowledge of legal transdisciplinary is of great importance to Islamic law students in Indonesia. Nevertheless, English reading proficiency of Indonesian students is problematic. The present research was to…

The current project investigates developmental aspects of acquiring locative verb constructions in English as a second language. Locative verbs, such as "to pour," "to spill," "to spray," and "to sprinkle," constitute a prototypical case of an overgeneralization problem in language learning: Whereas some of…

Lexical competence is considered as an important indicator of language proficiency. While learning vocabulary, learners need to remember various aspects of knowledge about the word (e.g., meaning, form and use). Many vocabulary learning strategies have been proposed to help learners consolidate vocabulary knowledge. Among them, grouping words…

In the present study, we take a longitudinal, corpus-based perspective to investigate short-term (over 9 months) linguistic change in the language produced for the spoken and written sections of the "TOEFL iBT"® test by a group of English-as-a-foreign-language (EFL) learners in China. The goal of the study is to identify patterns that…

Constructionist research on L2 learning has focused on the degrees to which skewed frequency (Goldberg, Casenhiser & White, 2007; Casenhiser & Goldberg, 2005; Goldberg, Casenhiser, & Sethuraman 2004) in a person's linguistic environment can facilitate "entrenchment," "schematization," and "contingency…

Learning to talk about motion in a second language is very difficult because it involves restructuring deeply entrenched patterns from the first language. In this paper we argue that statistical learning can explain why L2 learners are only partially successful in restructuring their second language grammars. We explore to what extent L2 learners…

Understanding the linguistic and rhetorical patterns of an academic discipline strengthens students' abilities to write in professional settings. Data-driven learning and corpus-linguistic methods can increase this understanding and should be considered valuable contributors to any writing curriculum. In this paper, I present a case history on…

This dissertation provides a comprehensive analysis of the L2 acquisition of Spanish psych-verbs (e.g. "gustar" "to like") across four different proficiency levels. In particular, psych-verbs constitute a testing ground for the predictions of the Interface Hypothesis (Sorace and Filiaci, 2006; Tsimpli, Sorace, Heycok &…
