In this study, we approximately replicated Papi and Khajavy’s (2021) investigation into the regulatory focus in second language acquisition, applying their approach to a significantly larger cohort of 855 Chinese second language (L2) learners. In contrast with the original study, our research employed the College English Test Band 4 (CET-4), a standardized English test, to better align with the Chinese educational context. This methodological shift allowed for a nuanced exploration of the regulatory focus’s role in language learning among Chinese students. Our results predominantly reinforce the crucial role of regulatory focus in language learning, echoing Papi and Khajavy’s findings. We discovered notable parallels in how promotion positively influences ideal own and ideal other, and how prevention negatively impacts ought own and ought other. However, a unique finding of our study was the stronger impact of ought selves on L2 anxiety and enjoyment in the Chinese context. This highlights the nuanced influence of socioeducational environments on regulatory focus strategies, suggesting contextual variability in language learning strategies.

The ability to acquire the speech sounds of a second language has consistently been found to be constrained with increasing age of acquisition. Such constraints have been explained either through cross-linguistic influence in bilingual speakers or as the result of maturational declines in neural plasticity with age. Here, we disentangle these two explanations by investigating speech production in adults who were adopted from China to Sweden as toddlers, lost their first language, and became monolingual speakers of the second language. Although we find support for predictions based on models of bilingual language acquisition, these results cannot be explained by the bilingual status of the learners, indicating instead a long-term influence of early specialization for speech that is independent of bilingual language use. These findings are discussed in light of first-language interference and the theory of maturational constraints for language acquisition.

In light of findings from research on informal foreign/second language (L2) learning, with a focus on English as a target language and using the concept of extramural English (EE), this position paper argues that learners’ engagement in EE (through activities such as watching television or films or playing digital games) constitutes an important individual difference (ID) variable that needs to be included in studies that aim to measure L2 English proficiency or development. In addition, it is suggested that if EE as an ID variable is left out in such studies in the future, the rationale for exclusion should be clearly stated. This position paper also discusses research instruments and methods used in this area of research, the benefits and drawbacks of different methods, and identifies research gaps and under-researched learner groups. Further, it is argued that in some contexts, EE has replaced classroom activities as the starting point for and foundation of learning English.

Response times (RTs) have become ubiquitous in second language acquisition (SLA) research, providing empirical evidence for the theorization of the language learning process. Recently, there have been discussions of some fundamental psychometric properties of RT data, including, but not limited to, their reliability and validity. In this light, we take a step back to reflect on the use of RT data to tap into linguistic knowledge in SLA. First, we offer a brief overview of how RT data are most commonly used as vocabulary and grammar measures. We then point out three key limitations of such uses, namely that (a) RT data can lack substantive importance without considerations of accuracy, (b) RT differences may or may not be a satisfactory psychometric individual difference measure, and (c) some tasks designed to elicit RT data may not be sufficiently fine-grained to target specific language processes. Our overarching goal is to enhance the awareness among SLA researchers of these issues when interpreting RT results and stimulate research endeavors that delve into the unique properties of RT data when used in our field.

High-quality replication studies are widely understood to be critical to the growth and credibility of our discipline, as shown in commentaries and discussion since the 1970s, at least. Nevertheless, misunderstandings and limitations in the aims, designs, and reporting of replication research remain, thus reducing the usefulness and impact of replications. To address this issue and improve the rigor, quality, and conduct of replication studies in applied linguistics, a new standard for reporting replication studies that captures several critical features of replication research not discussed in current reporting guidelines is proposed. Importantly, this standard applies basic expectations in replication reporting so that outcomes can be better understood and evaluated. By applying this standard, replication studies will better meet their aims to confirm, consolidate, and advance knowledge and understanding within applied linguistics and second language research. In addition, readers will more easily understand how the replication study was carried out and be able to better evaluate the claims being made.

This paper aims to guide the training of all Latin instructors and learners who want to optimise the process of acquiring the language by applying the results of research carried out in the field of Second Language Acquisition (SLA), specifically here those related to the acquisition of vocabulary. Consequently, some theoretical considerations on the psycholinguistic operations that govern vocabulary learning are first offered, in order to build a better understanding of language acquisition and to make instructors and learners more knowledgeable about the vocabulary learning process, from the noticing of an unknown word and its integration into the subject's competence to the expansion and development of knowledge about the acquired words. The theoretical aspects of vocabulary learning will be illustrated at all times with practical examples taken from methods and books for learning Latin, as well as, in the fourth section, with a wide catalogue of practical advice – must-do items for the class – that can be easily implemented by Latin instructors.

This study examines the acquisition of kind-referring expressions such as The dodo is extinct. The objective is to investigate whether second language (L2) learners’ acquisition of nominal number marking and articles expressing kind-reference in English is affected by their first language (L1), their L2 proficiency in English, or the syntactic position of the kind-referring noun phrase (NP). L2 learners of English with Arabic, Chinese, and Turkish L1 backgrounds and a control group of native English speakers (NSs) participated in the study. The results from a Fill in the Gaps Task (FGT) and an Acceptability Judgment Task (AJT) demonstrated that L2 learners were more successful in their production and acceptability judgments when the expression of kind-reference in the target language was similar to that in their L1. The results also showed non-facilitative L1 transfer in the domain of bare singulars, as well as a positive effect of higher L2 proficiency on kind-referring NPs. Finally, the study revealed a subject/object asymmetry in the acquisition of kind-referring NPs in L2 English.

The present study investigates the interplay between proficiency and empathy in the development of second language (L2) prosody by analyzing the perception and processing of intonation in questions and statements in L2 Spanish. A total of 225 adult L2 Spanish learners (L1 English) from the Northeastern United States completed a two-alternative forced choice (2AFC) task in which they listened to four utterance types and categorized them as either questions or statements. We used Bayesian multilevel regression and drift diffusion modeling to analyze the 2AFC data as a function of proficiency level and empathy scores for each utterance type. We show that learner response accuracy and sensitivity to intonation are positively correlated with proficiency, and this association is affected by individual empathy levels in both response accuracy and sentence processing. Higher empathic individuals, in comparison with lower empathic individuals, appear to be more sensitive to intonation cues in the process of forming sound-meaning associations, though increased sensitivity does not necessarily imply increased processing speed. The results motivate the inclusion of measures of pragmatic skill, such as empathy, to better account for intonational meaning processing and sentence comprehension in second language acquisition.
