It is widely accepted that written corrective feedback (WCF) is an effective tool for helping learners develop their L2 knowledge. Yet, it remains inconclusive as to which type of WCF can best facilitate L2 learning. In recent years, many second language acquisition (SLA) researchers agree that "direct" and "focused" WCF may be…

The goal of this study is to contribute to the field of Japanese pedagogy by examining how Japanese native speakers and learners of Japanese as a foreign language with American cultural backgrounds take stances in discussions in Japanese. As stancetaking is a fundamental human behavior (Du Bois & Karkkainen, 2012; Iwasaki, 2015; Kiesling,…

This study examines how listening comprehension difficulties (LCDs) vary among college-level learners of English as a Foreign Language (EFL), with a focus on the roles of gender and language proficiency. Listening comprehension is an essential component of language learning, presenting notable challenges for EFL students. These challenges are…

In recent years, Third Language Acquisition (TLA) in Cross-Linguistic Influence (CLI) research has been debated regarding background languages' impact on learning a target language. While Second Language Acquisition (SLA) research often emphasizes the primary influence of the first language (L1) on the target language, it does not discount the…

This book traces and summarizes the author's theoretical insights and empirical findings in the field of foreign language education. The volume explores themes such as individual differences in L1 ability and their connection to L2 aptitude and L2 achievement, L2 anxiety as an affective or cognitive variable, and the relationship between L1 and L2…

Research on the factors influencing the acceptance of GenAI in language learning has expanded widely; however, few studies have focused on the role of language learning emotions. To enhance the effectiveness of GenAI-powered English-speaking instruction and the learning experience, this study expands on the Integrated Model of Technology…

In this report, we perform a descriptive analysis of kindergarten readiness in Illinois. We use data on the population of Illinois kindergarteners between the 2017-18 and 2021-22 school years provided by the Illinois State Board of Education (ISBE). In our analysis, we build on the existing literature and examine readiness over time, by domain,…

The first goal of this study was to examine how individual differences in initial L2 proficiency help explain L2 grammar development in oral production during short-term immersion abroad. The second goal of the study was methodological, and evaluated challenges that can result from operationalizing learners' initial L2 proficiency as pretest…

This cross-sectional study addresses for the first time the non/linear association between individual learner differences of social, proficiency-related, and socioaffective nature (length of residence [LoR], varietal proficiency, exposure, and socioaffect) and differential outcomes in L2 sociolinguistic repertoires against the backdrop of the…

This study is the first to investigate subject-level variability in sociolinguistic evaluative judgements by 30 adult L2 German learners and explore whether the observed variability is characterizable as a function of individual differences in proficiency, exposure, and motivation. Because group-level estimates did not paint an accurate picture of…

Individual differences in episodic memory abilities have been linked to second language (L2) lexical development, both theoretically and empirically, but such empirical support has been limited to the earliest phases of word learning. However, the Episodic L2 Hypothesis predicts that L2 lexical representations in more advanced L2 speakers are…

The undeniable importance of reading in higher education prompted this investigation into the reading skills of a group often overlooked in previous research: master's level students studying in English-medium instruction (EMI) environments. Participants (148 master's-level students of engineering) completed the Nelson-Denny Reading Test (Form G),…

Recent years have witnessed a growing interest in case studies and surveys by researchers of second language acquisition (SLA) and cognitive (neuro-)science to probe into the group of exceptionally talented multilingual learners or polyglots who can understand and speak an impressive number of multiple foreign languages other than their own mother…

Due to successive immigration waves, many European countries are experiencing a rise in ethnic minoritized families. In this study, we investigate how risks and resources associated with multilingualism at the individual and the family level shape minoritized children's reported happiness and whether these effects are independent of children's…

To date, most classroom-based research into the learning of a third language (L3) in the US has examined patterns of acquisition among various groups of bilinguals. Situated mainly within the context of "Portuguese for Spanish Speakers" (PSS), studies typically group learners based on the sequence / age of onset of their main background…
