This study closely replicates the analyses of the third research question in Römer and Berger (2019), which reported that the associations between verbs and verb argument constructions (VACs) used by German and Spanish learners of English move closer to a native usage norm as the learners’ proficiency increases. This study conducted the same correlation analyses from the original study but with a substantially expanded version of the learner corpus used therein. Additionally, we conducted zero-inflated negative binomial analyses to estimate the relationship between the frequencies of verb-VAC combinations in the British National Corpus (BNC) and in the learner subcorpora representing different proficiency levels. Our findings were consistent with the original study in showing significant positive correlations between frequencies of the verb-VAC combinations in the BNC and in the learner subcorpora but further revealed the potential effect of topic on the learners’ VAC usage. Implications for future studies are discussed.

This paper reports a complete secondary analysis of Jeon and Yamashita’s (2022) systematic review to build the second language (L2) model of the simple view of reading (SVR). The same meta-analytic methodologies were maintained, with the exception of applying meta-analytic structural equation modeling (MASEM). This study successfully replicated some of the aggregated correlations but not others, owing to (a) the recoding of the original raw data to recreate a dataset and (b) the motivated change in sample selection from a longitudinal study for MASEM. The MASEM results extended previous findings that L2 comprehension skills contribute more to L2 reading comprehension than L2 decoding skills, and together explain a large amount of variance in L2 reading comprehension. The SVR model with metalinguistic skills showed their contribution to L2 decoding and comprehension skills, but no direct impact on L2 reading comprehension, supporting the parsimonious structure of SVR in L2.

Darcy et al. (2016) examined the relationship between language abilities and general cognition, or specifically, how inhibitory control might relate to L2 speech perception and production. Given that their findings unexpectedly indicated a stronger relationship between inhibitory control and perception in comparison to inhibitory control and production, and because inhibitory control was measured using a single, retrieval-induced inhibition task, the current study is a close replication with the inclusion of two additional tasks of intentional inhibition: the Stroop task and the Simon task. A comparison of the descriptive statistics for the tests of phonological processing and retrieval-induced inhibition between the initial study and current replication indicated negligible differences between the two participant samples. However, results of the partial correlation analyses in the current replication did not indicate clear relationships between phonological variables and inhibitory control. Possible explanations for the different patterning of results and implications for future replications are discussed.

This study is a close replication of Kanwit and Geeslin (2014), a variationist investigation of the interpretation of verbal moods in adverbial clauses in Spanish. Whereas the first language (L1) of the second-language participants in the initial study was English, we explore whether Kanwit and Geeslin’s results extend to other L1 populations—Swedish and French learners of Spanish. Participants in the replication study completed the same interpretation task and grammar test as those in the initial study. Results showed, for example, that multiple factors influenced their variable interpretation of verbal moods, there was evidence of change between course levels, and there were certain differences in interpretation between the French and Swedish groups. This study contributes to knowledge about the interpretation of a variable structure by enhancing the confirmatory power of some of the initial study’s findings, while also suggesting that the learners’ L1 leads to diverging findings.

Elicited imitation (EI) tasks are a practical tool for measuring second language (L2) knowledge and skills. In this study, we implemented a web-based EI task that measures English morphosyntactic knowledge and compared its measurement properties to a traditional laboratory-based EI. A cohort of 149 L2 English learners engaged in the web-based EI task, and 151 participants completed a traditional lab-based EI counterpart. Correlation analyses revealed a significant, comparable relationship between English proficiency and the two EI versions, with the ungrammatical items showing less consistency that neither improved nor harmed the overall EI effectiveness. Factor analyses corroborated the validity of web-programmed EI, with both EI versions relating similarly to time-pressured, implicit knowledge and untimed, explicit knowledge measures. Our results suggest the potential for utilizing web-based EI to substitute lab-based tasks, enabling larger-scale, more diverse sampling. We end with implications for future web-based EI task users and include a coding guideline for customized web-based EI use.

This study expands on previous research into filler-gap dependency processing in second language (L2) English, by means of a replication of Canales’s (2012) self-paced reading study. Canales, among others, found that advanced L2-English speakers exhibited the same processing behavior that Stowe (1986) found for native English processing: On encountering a filler, they posited gaps in licensed positions and avoided positing gaps in grammatically unlicensed island positions. However, the previous L2 studies focused on advanced-level L2 proficiency and did not test specifically for first language (L1) influence. The present study compares two groups of intermediate-level L2-English speakers with contrasting non-wh-movement L1s, Jordanian Arabic and Mandarin, to investigate the effects of L1 influence and individual differences in proficiency. Our results provide evidence that at intermediate level, too, L2 filler-gap processing adheres to grammatical constraints. L1 did not affect this behavior, but proficiency effects emerged, with larger licensed filled-gap effects at higher proficiency.

Boduch-Grabka and Lev-Ari (2021) showed that so-called “native” British-English speakers judged statements produced by Polish-accented English speakers as less likely to be true than statements produced by “native” speakers and that prior exposure to Polish-accented English speech modulates this effect. Given the real-world consequences of this study, as well as our commitment to assessing and mitigating linguistic biases, we conducted a close replication, extending the work by collecting additional information about participants’ explicit biases towards Polish migrants in the UK. We did not reproduce the original pattern of results, observing no effect of speaker accent or exposure on comprehension or veracity. In addition, the measure of explicit bias did not predict differential veracity ratings for Polish- and British-accented speech. Although the current pattern of results differs from that of the original study, our finding that neither comprehension nor veracity were impacted by accent or exposure condition is not inconsistent with the Boduch-Grabka and Lev-Ari (2021) processing difficulty account of the accent-based veracity judgment effect. We explore possible explanations for the lack of replication and future directions for this work.

Multilingualism in the context of academic publishing involves beliefs and actions manifested through publications in multiple languages. However, a systematic analysis of how academic journals practice multilingualism has been scant. Therefore, the present study analyzed how indexed journals of applied linguistics promote and practice multilingualism following their scopes and language policies (LPs). Initially, 67 journals underwent screening based on their “aims and scope,” resulting in 11 journals that actively promoted multilingualism. Employing a critical discourse analysis (CDA) framework, the main analysis focused on the assumptions embedded within the journals’ LPs. The findings indicated an incongruity between the journals’ stated commitment and their practices of multilingualism. Specifically, all the journals mandated submissions exclusively in English with implicit biases toward native speakerism. The study underscores the need for a collective effort within and beyond the applied linguistics community to address linguistic biases and for more equitable and inclusive academic publishing practices.

Digital educational game-based apps can be effective in helping young children develop language skills, particularly when paired with formal instruction. However, we need to know more about how educational games benefit learning in the absence of formal instruction, given children’s proficiency with and willingness to use mobile devices anytime, anywhere. This study uses a randomized controlled trial design to investigate the impact of a digital app—ABCmouse English—on L2 learning of seven- and eight-year-old Japanese children over a 16-week period. Pre- and post-assessments of the children’s English proficiency, together with an analysis of when and how they played with the app, were used to shed light on the relationship between the children’s in-app game choices and their language learning outcomes. Surveys and interviews with parents provide qualitative insights and information about the experiences of children and their families while using the app and its impact on their development as language learners.

As part of ongoing efforts to characterize the extent to which tasks and interaction-driven language learning are influenced by individual differences (IDs), task-based researchers have thus far examined variables like learners’ levels of L2 anxiety, motivation, cognitive creativity, working memory capacity, and aptitude. Building on a tradition of prior syntheses in task-based language teaching (TBLT, e.g., Plonsky & Kim, 2016), we carried out a methodological review of the practices used by researchers who have examined learners’ IDs in task-based language learning. We searched journal articles published between 2000 and 2023 and identified 135 unique samples for analysis. Each empirical study was coded for relevant contextual and demographic variables as well as for methodological features related to the investigation of individual differences. We observed that of 30 individual differences investigated in TBLT research over the last two decades, the top five most common were motivation, working memory, L2 proficiency, anxiety, and aptitude. Interesting patterns related to operationalizations, instruments, coding, analyses, and reporting practices. In this paper, we report these results and summarize the most and least common methodological practices, also pointing out gaps and possibilities for future directions. We conclude with recommendations for researchers interested in embarking on empirical investigations of individual differences and TBLT based on best practices.

Usage-based theory has proposed that learning of linguistic constructions is facilitated by input that contains few high-frequency exemplars, in what is known as a skewed (or Zipfian) input distribution. Early empirical work provided support to this idea, but subsequent L2 research has provided mixed findings. However, previous approaches have not explored the impact that cognitive traits (e.g., working memory) have on the effectiveness of skewed or balanced input. The experiment reported here tested learners’ ability to develop new L2 categories of adjectives that guide lexical selection in Spanish verbs of “becoming.” The results showed that, when explicit rules are provided, low-working memory learners benefitted from reduced variability in skewed input, while high-working memory individuals benefitted from balanced input, which better allows for rule-based hypothesis testing. The findings help clarify the mixed findings in previous studies and suggest a way forward for optimizing the L2 input based on individual traits.

The development of L2 utterance fluency has been extensively researched, whereas that of cognitive fluency has rarely been examined. This study investigated the longitudinal development of L2 utterance and cognitive fluency and their relationship. Thirty-one Chinese learners of English completed speaking tasks and a set of tasks for cognitive fluency before and after 5 months’ study abroad. The results showed that participants made a significant improvement in mean syllable duration, end-clause pause frequency, and the speed of syntactic encoding and articulation but not in mid-clause pause frequency or lexical retrieval speed. Mixed-effects modeling confirmed a significant relationship between syntactic encoding speed and mean syllable duration and mid-clause pausing. Furthermore, the significant relationships were maintained over time. The findings highlight (a) the differences between mid-clause and end-clause pausing in terms of their developmental patterns and relationship with cognitive fluency and (b) a significant role of syntactic encoding speed in L2 utterance fluency.

It has been proposed that second language (L2) learners differ from native speakers in processing due to either influence from their native language or an inability to integrate information from multiple linguistic domains in a second language. To shed new light on the underlying mechanism of L2 processing, we used an event-related potentials (ERP) paradigm to examine the processing of sentences with only in English by native speakers of English and advanced Dutch learners of English. Successful processing of sentences with only requires rapid integration of prosodic information with semantic and syntactic information. We found that L2 listeners showed native-like processing of the acoustics of contrastive pitch accents when adjacent to only. However, they needed more cues than L1 listeners to perform native-like in forming expectations for focus placement. Our results thus provide first ERP-based evidence for difficulty in the integration of information for focus expectation in difficult L2 constructs.

Researchers in second language (L2) and education domain use different statistical methods to assess their constructs of interest. Many L2 constructs emerge from elements/parts, i.e., the elements define and form the construct and not the other way around. These constructs are referred to as emergent variables (also called components, formative constructs, and composite constructs). Because emergent variables are composed of elements/parts, they should be assessed through confirmatory composite analysis (CCA). Elements of emergent variables represent unique facets of the construct. Thus, such constructs cannot be properly assessed by confirmatory factor analysis (CFA) because CFA and its underlying common factor model regard these elements to be similar and interchangeable. Conversely, the elements of an emergent variable uniquely define and form the construct, i.e., they are not similar or interchangeable. Thus, CCA is the preferred approach to empirically validate emergent variables such as language skills L2 students’ behavioral engagement and language learning strategies. CCA is based on the composite model, which captures the characteristics of emergent variables more accurately. Aside from the difference in the underlying model, CCA consists of the same steps as CFA, i.e., model specification, model identification, model estimation, and model assessment. In this paper, we explain these steps. and present an illustrative example using publicly available data. In doing so, we show how CCA can be conducted using graphical software packages such as Amos, and we provide the code necessary to conduct CCA in the R package lavaan.

The present study uses self-paced reading as a measure of online processing and an acceptability judgement task as a measure of offline explicit linguistic knowledge, to understand L2 learners’ comprehension processes and their awareness of subtle differences between the modal auxiliaries may and can. Participants were two groups of university students: 42 native speakers of English and 41 native speakers of Croatian majoring in L2 English. The study is part of a larger project that has provided empirical evidence of the two modals, may and can, being mutually exclusive when denoting ability (can) and epistemic possibility (may) but equally acceptable in pragmatic choices expressing permission. The present results revealed that L1 and L2 speakers rated the acceptability of sentences in offline tasks similarly; however, L2 learners showed no sensitivity to verb–context mismatches in epistemic modality while demonstrating sensitivity when processing modals expressing ability. Implications for L2 acquisition of modals and future research are discussed.

There has been increasing interest in the effects of note taking in second language (L2) research. However, no meta-analysis has been conducted to examine the relationship between note taking and learning through exposure to L2 input. We retrieved 28 effect sizes from 21 studies (N = 1992) to explore the overall effects of note taking as well as to examine the extent to which the effectiveness of note taking is likely to vary as a function of a set of potential moderators (i.e., learner variables, treatment variables, note-taking features, learning target, and measurement type). Results revealed that note taking had a small to medium positive overall effect on learning through exposure to L2 input (g = 0.56, 95% CI: 0.24–0.88). Subsequent moderator analyses revealed that variability in the size of note-taking effects across studies was explained by learner variables (context, region, orthographic scripts, institutional level), treatment variables (mode of input, material type), note-taking features (note-taking behavior, number of note-taking sessions, provision and type of note-taking strategy instruction, total length of instruction, opportunity to review notes), learning target, and measurement type. Based on the obtained findings, teachers are recommended to incorporate note taking in L2 classrooms. Pedagogical suggestions and directions for future research are also provided.

Despite the widespread use and effectiveness of the Modern Language Aptitude Test (MLAT) composite score in predicting individual differences in L2 achievement and proficiency, there has been little examination of MLAT subtests, although they have potential for illuminating components of L2 aptitude and the mechanism of prediction. Here we use regression commonality analysis to decompose the predictive variance from the MLAT into unique components for each subtest alone and for each possible combination of subtests (duos, trios, etc.) that may have shared variance. The results, from a longitudinal study of 307 U.S. secondary students during 2 years of Spanish learning, provide strong evidence for the role of literacy-related skills in all subtests and in predicting all L2 outcomes. These and other results support a view of L1 literacy and language skills leading to metalinguistic development, which in turn leads to stronger L2 aptitude and achievement.

Concerns have recently been raised about the validity of scales used in the L2 motivational self system tradition, particularly in relation to sufficient discriminant validity among some of its scales. These concerns highlight the need to systematically examine the validity of scales used in this tradition. In this study, we therefore compiled a list of 18 scales in widespread use and administered them to Korean learners of English (N = 384). Testing the factorial structure of these scales using multiple exploratory and confirmatory factor-analytic criteria revealed severe discriminant validity issues. For example, the ideal L2 self was not discriminant from linguistic self-confidence, suggesting that participant responses to such ideal L2 self items is not driven by actual–ideal discrepancies as previously presumed but more likely by self-efficacy beliefs. We discuss these results in the context of the need to encourage systematic psychometric validation research in the language motivation field.
