The question of cognition in second language (L2) acquisition later in life is of importance inasmuch as L2 learning is largely mediated by domain-general cognitive capacities. While a number of these capacities have been shown to decline with age, individual differences in cognition increase over the lifespan. This microdevelopment study…

The present dissertation analyzed speech production and perception in early heritage Spanish-English bilingual children. Specifically, I investigated how perception and production of lexical stress develops in bilingual children. Current models of second language (L2) speech perception do not include heritage bilinguals or suprasegmental aspects…

Practice is necessary for developing oral English proficiency, but many Chinese learners of English lack the self-confidence to practice oral English; furthermore, students' self-confidence deficiency is perpetuated by insufficient oral English proficiency. The purpose of this qualitative case study was to discover pedagogical practices that break…

Cognitive flexibility (switching) and control (inhibition) are among widely accepted cognitive advantages of bilingualism. Switch Cost (SC), i.e., the time difference to complete a switch versus non-switch task, is a construct for measuring the switching ability. The need to control the interference and switching between one's languages leads to…

The purpose of this non-experimental, correlational, explanatory, cross-sectional design with quantitative methods was to examine the relationship between the length of the school day and the percentage of students who achieved Met Expectations and Exceeded Expectations scores on the 2018 Partnership for Assessment of Readiness for College and…

The unforeseen shift to virtual learning during the COVID-19 pandemic required instructors and students to face unprecedented learning challenges. Under these circumstances, Chinese international students who intended to come to the U.S. to begin their studies were required to remotely access their courses while still residing in China, which…

We investigated age-related decline in adult learning of Dutch as an additional language (Ln) in speaking, writing, listening, and reading proficiency test scores for 56,024 adult immigrants with 50 L1s who came to the Netherlands for study or work. Performance for all four language skills turned out to decline monotonically after an age of…

This study examined the effectiveness of guided data-driven learning (DDL) activities on helping technological university students with a lower-intermediate proficiency level to learn grammar and vocabulary topics for the TOEIC test. The question of whether inductive learners make more progress than deductive learners was also addressed. A total…

The Eastern Economic Corridor (EEC) is a promising project which aims to elevate the living standards of the Thai people. Large numbers of skilled workers with a good command of the English language are urgently needed. The present study aims to examine the English proficiency of Thai employees and explore the expectations of employers in the EEC.…

The following article attempts to characterise the current changes in the communication of people living in the area of Polish-Czech borderland based on the results of the study conducted in 2018 and 2019. The aim is to determine the dominant mode of supranational communication, as well as the reason behind its prevalence by analysing the language…

Bilingual children with a limited command of the second language (L2) often yield unsatisfactory results in L2-based non-word repetition tasks (NWRT) for the assessment of working memory. In this study, monolinguals (MO) and bilinguals (BI) of preschool age acquiring German were compared in regard to their performance on German-based NWRT to…

This study builds on prior research on second language (L2) Spanish psych verbs, which has centered on morphosyntactic properties, by examining their syntactic distribution, which relies on lexical semantic knowledge. The fact that certain forms are licensed for some verbs, but not others, is the result of an underlying lexical semantic difference…

This study investigates the acquisition of null subjects by Mandarin Chinese native speakers ('Chinese NSs' hereafter), with different levels of L2 English proficiency, at initial stages of L3 Italian acquisition. The aim is to find out if, when acquiring Italian null subjects, Chinese NSs resort to their L1, which, like the L3, allows null…

With the outbreak of the COVID-19 pandemic, educational institutions worldwide adapted their teaching and learning techniques for various courses, including English. One of the adaptations includes a well-known model called Flipped Classroom (FC). FC often mixes two stages: pre-class that is online, and in-class that is face-to-face. Though the…

Previous studies on spoken word production have shown that native English speakers used phoneme-sized units (e.g., a word-initial phoneme, C) to produce English words, and native Mandarin Chinese speakers employed syllable-sized units (e.g., a word-initial consonant and vowel, CV) as phonological encoding units in Chinese. With spoken word…
