Purpose: Insights from linguistic variation research illustrate a linguistically diverse population, in which even speakers who can be classified as speaking a "mainstream" variety have grammatical knowledge of vernacular or "nonmainstream" features. However, there is a gap in our knowledge regarding how vernacular features are…

This brief report presents the results of a re-analysis of data by Yi, Man, and Maie (2023), who investigated L1 and L2 intuitive knowledge of phrasal frequency and collocation strength in multiword sequences. We utilized an individual-differences approach and examined which participant variables (age of onset, length of residence, language use,…

The present study employs regulatory focus theory (Higgins, 1997) to investigate the effects of L2 speakers' chronic regulatory focus on their L2 pragmatic versus grammatical awareness. It involved the participation of 121 Chinese students, who are English language learners, at a university in the United States. Haws et al.'s (2010) questionnaire…

This study longitudinally examined the effects of cognitive and sociopsychological individual differences (aptitude, motivation, personality) and the quantity and quality of second language (L2) experience on L2 speech gains in naturalistic settings. We elicited L2 spontaneous speech from 50 Chinese learners of English at the beginning and the end…

We examined the use of code-switching as a strategy in communication. This study investigates the impact of switching patterns on language processing by observing the Indonesian-English Codeswitching practiced by one of the most prominent hotel employees in Makassar, Indonesia. This study applied a descriptive qualitative method to find the…

An aim of research on bilingualism is to understand how the brain adapts to the use of more than one language. Although several important discoveries and insights about the consequences of bilingualism have been generated over the last several decades, concerns about replicability have narrowed the scope of inquiry and discussion to the…

Second Language Pragmatics (L2 pragmatics) research focused on the study abroad (SA) context points out the benefits of this context for second language (L2) pragmatic development while also illustrating the non-linearity of this development, as it is shaped by different contextual factors and individual differences. Nevertheless, this research…

This paper examines evidence for relationships among individual differences (IDs) in L1 achievement, L2 aptitude, and L2 achievement. It begins by providing an overview of my academic journey from L1 educator to L2 researcher and explains the development of the Linguistic Coding Differences Hypothesis (LCDH). Next, I review Peter Skehan's…

Despite the growing body of studies on collocation learning in SLA research, there are hardly any studies taking the perspective of the individual learner or studies that have examined the effect of individual differences. This study--a qualitative component of a mixed-methods longitudinal project--presents an in-depth exploration of the intro-…

Recent research suggests that psychotypology may be one of the main factors determining L3 acquisition and use, especially so in the early stages. However, the existence and nature of multilingual learners' perception of language proximity have often only been assumed rather than measured, and rarely addressed with respect to the increasingly…

In this preregistered, longitudinal study of early code-switching, 34 US-born, Spanish-English bilingual children were recorded with a bilingual family member at 2;6 and 3;6, in Spanish-designated and English-designated interactions. Children's Spanish and English expressive vocabulary and their exposure to code-switching were measured through…

The study investigated the beliefs expressed by a sample of 206 Polish and Spanish teacher-trainees about the use of learners' native language (L1) in teaching English as a foreign language (EFL). Quantitative and qualitative data from a questionnaire revealed considerable differences between the two nationality groups in their beliefs about both…

This qualitative study uses a semi-structured interview to investigate why Saudi learners stop learning a third language and whether these reasons are permanent or temporary. The participants were six female master's degree students who had experience learning a third language outside of formal education or informal settings. This study identifies…

Extant research has compared the processing of affectively laden words between L1 and L2. However, most studies used verbal stimuli that were validated for a single language or for both languages but using independent samples. We systematically compared ratings of valence, emotional intensity and subjective familiarity of negative, neutral,…

This study investigated primary students' perceptions of Content and Language Integrated Learning (CLIL) Natural Science and Social Sciences and variations in perceptions by individual and social factors. The sample comprised 524 Spanish-speaking students aged 9-13 years from bilingual Spanish-English schools in Andalusia (Spain). The study…
