As the field of heritage language acquisition expands, there is a need for proficiency to compare speakers across groups and studies. Elicited imitation tasks (EITs) are efficient cost-effective tasks with a long tradition in proficiency assessment of second language (L2) learners, first language children, and adults. However, little research has investigated their use with heritage speakers (HSs), despite their oral nature, which makes them appropriate for speakers with variable literacy skills. This study is a partial replication of Solon, Park, Dehghan-Chaleshtori, Carver & Long (2022), who administered an EIT originally developed for advanced L2 learners on a group of HSs. In this study, we administered the same EIT with minor modifications to 70 HSs and 132 L2 learners of Spanish with different levels of proficiency and ran a Rasch analysis to evaluate the functioning of the task with the two groups. To obtain concurrent validity evidence, scores on the EIT were compared with participants’ performance in an oral narration; evaluated for complexity, accuracy, and fluency (CAF); and compared with a standardized oral proficiency test, the Versant Spanish Test. Results of Rasch analyses showed that the EIT was effective at distinguishing different levels of ability for both groups, and analyses showed moderate to strong correlations between CAF measures and the EIT and very strong correlations between the EIT and the Versant Spanish Test. These results provide evidence that the EIT is an efficient and adequate proficiency test for HSs and L2 learners of Spanish; its use in research settings is recommended.

There has been a growing emphasis on researching foreign language boredom in second language acquisition in recent years. However, existing research has yet to reach a consensus regarding the effect of foreign language boredom on learners’ learning achievement. To address this gap, the present study employs multilevel meta-analysis to analyze 47 effect sizes from 33 empirical studies involving a total sample size of 27,838 participants. The findings reveal that foreign language boredom illustrates a small negative effect (r = -.24, p < .001) on language achievement. Furthermore, the moderation analysis reveals that the magnitude of the effect size varies crossing educational stages, achievement measurements, domain-specific language skills, foreign language boredom measurements, teaching modes, and learning contexts. This study provides robust evidence to support the detrimental role of foreign language boredom in language acquisition and identified substantive gaps in this research field, offering valuable directions for future research.

This article explores the utility of content-embedded working memory capacity (WMC) tasks for advancing second language (L2) research. While both complex span and content-embedded tasks implement a dual-task paradigm that requires processing and maintenance of information, they differ in that the former demand maintenance of extraneous memory elements during processing, while the latter demand processing and maintenance of the same elements. Since manipulating information stored in working memory is critical for L2 processing and development, particularly in intentional learning contexts, content-embedded tasks may serve as strong predictors of several linguistic outcomes. We report preliminary evidence suggesting that both content-embedded tasks (available in IRIS [https://www.iris-database.org/details/iv6nR-HD9NQ]) and complex span tasks can be significant predictors of explicit L2 aptitude and L2 reading comprehension, but that content-embedded tasks can show advantages over complex span tasks in some instances. We discuss methodological implications for the measurement of WMC in L2 research.

This paper reports an expansion of the English as a second language (L2) component of the Multilingual Eye Movement Corpus (MECO L2), an international database of eye movements during text reading. While the previous Wave 1 of the MECO project (Kuperman et al., 2023) contained English as a L2 reading data from readers with 12 different first language (L1) backgrounds, the newly collected dataset adds eye-tracking data on English text reading from 13 distinct L1 backgrounds (N = 660) as well as participants’ scores on component skills of English proficiency and information about their demographics and language background and use. The paper reports reliability estimates, descriptive statistics, and correlational analyses as means to validate the expansion dataset. Consistent with prior literature and the MECO Wave 1, trends in the MECO Wave 2 data include a weak correlation between reading comprehension and oculomotor measures of reading fluency and a greater L1-L2 contrast in reading fluency than reading comprehension. Jointly with Wave 1, the MECO project includes English reading data from more than 1,200 readers representing a diversity of native writing systems (logographic, abjad, abugida, and alphabetic) and 19 distinct L1 backgrounds. We provide multiple pointers to new venues of how L2 reading researchers can mine this rich publicly available dataset.

Growing evidence suggests that ratings of second language (L2) speech may be influenced by perceptions of speakers’ affective states, yet the size and direction of these effects remain underexplored. To investigate these effects, 83 raters evaluated 30 speech samples using 7-point scales of four language features and ten affective states. The speech samples were 2-min videorecordings from a high-stakes speaking test. An exploratory factor analysis reduced the affect scores to three factors: assuredness, involvement, and positivity. Regression models indicated that affect variables predicted spoken language feature ratings, explaining 18–27% of the variance in scores. Assuredness and involvement corresponded with all language features, while positivity only predicted comprehensibility scores. These findings suggest that listeners’ perceptions of speakers’ affective states intertwine with their spoken language ratings to form a visual component of second-language communication. The study has implications for models of L2 speech, language pedagogy, and assessment practice.

This study explored how second language (L2) speakers’ use of multiword sequences in speech predicted perceived fluency ratings while controlling for their utterance fluency. A total of 102 Japanese speakers of English delivered an argumentative speech, which was analyzed for bigram and trigram measures (frequency, proportion, and mutual information) and utterance fluency measures capturing three subdimensions: speed, breakdown, and repair fluency (Tavakoli & Skehan, 2005). Perceived fluency was assessed by 10 experienced L2 raters. Mixed-effects regression analyses revealed that after establishing the parsimonious model solely by UF predictors (marginal R2 = .61), a frequency-based n-gram predictor––bigram proportion––slightly but significantly explained the remaining variance of fluency rating scores (0.8%). The results indicated that multiword sequences in speech had a small but systematic impact on perceived fluency, even controlling for the effects of utterance fluency. This finding contributes to the discussion concerning the role of multiword sequences in fluent speech production.

While our earlier report focused on the initial four months of the dataset (Saito et al., 2018, Language Learning), this study investigates the relationship between individual differences in motivation (Ideal Self and Ought–to Self), emotions (Enjoyment and Anxiety), and L2 speech learning among 121 Japanese English–as–a–Foreign–Language high school students over 1.5–years. Participants’ L2 speech proficiency consistently improved at each testing point (6 months, 10 months, and 1.5 years), while their motivation and emotions, measured through questionnaires, remained relatively stable. The results of structural equation modeling suggest that the relationship between motivation, emotions, and acquisition may evolve. Within the first 6-10 months, data indicated a correlational relationship, highlighting a mutual influence among motivation, emotions, and acquisition. However, as the study progressed beyond one year, after students had fully adapted to their educational settings, a clearer causal relationship emerged: Enhanced motivation and more positive emotions were linked to increased classroom practice, leading to significant gains in L2 speech proficiency. The predictive roles of Anxiety remained unclear in this longitudinal dataset.

Morphological knowledge refers to the ability to recognize and use morphemes correctly in syntactic contexts and word formation. This is crucial for learning a morphologically rich language like Finnish, which features both agglutinative and fusional morphology. In Finnish, agglutination occurs in forms like aamu: aamu+lla (‘morning: in the morning’), where a suffix is transparently added. Fusional features, as seen in ilta: illa+lla (‘evening: in the evening’), involve allomorphic stem changes that reduce transparency. We investigated the challenges posed by stem allomorphy for word recognition in isolation and in context for L2 learners and L1 speakers of Finnish. In a lexical decision task, L2 speakers had longer response times and higher error rates for semitransparent inflections, while L1 speakers showed longer response times for both transparent and semitransparent inflection types. In sentence reading, L2 speakers exhibited longer fixation times for semitransparent forms, whereas L1 speakers showed no significant effects. The results suggest that the challenges in L2 inflectional processing are more related to fusional than agglutinative features of the Finnish language.

The duality of human nature, consisting of positive and negative personality traits, has intrigued scholars in different fields. Despite an overwhelming dominance of research on positive characteristics, particularly in the field of education, negative traits, such as those constituting the Dark Triad (DT; i.e., Psychopathy, Narcissism, and Machiavellianism) have been confirmed to be associated with both positive and detrimental outcomes. This paper aims to investigate the potential influence of these aversive traits on second language (L2) learning outcomes—L2 learning motivation, engagement, achievement, and willingness to communicate. L2 learners from a single country (n = 431) participated in this study. Multiple structural equation models (SEMs) were run to analyze the links and the directionality of significant effects. Overall, among the undesirable DT traits, Psychopathy and Narcissism were both positive and negative predictors of the L2 outcomes, while Machiavellianism unexpectedly emerged solely as a positive predictor. The intricacy of the results underscores the vague nature of the effects, pinpointing the need for more caution while examining negative personality traits in education and the L2 contexts. Based on the results of this study, implications and directions for future research on DT and language learning are suggested.

Fluency, intelligibility, comprehensibility, and accentedness are important dimensions of second language (L2) pronunciation proficiency representing global, listener-based intuitions. This study meta-analyzed 49 reports from 1995 to 2023, examining 141 effect sizes (Pearson r) to understand their relationships and possible moderators. Three-level meta-analysis models showed weighted mean correlations of .82, .75, .62, .57, and .32 for fluency/comprehensibility, comprehensibility/accentedness, fluency/accentedness, intelligibility/comprehensibility, and intelligibility/accentedness, respectively. Task types moderated correlations for fluency/accentedness, intelligibility/comprehensibility, and intelligibility/accentedness, with controlled tasks leading to higher correlations. Ratings of multiple dimensions by the same listeners tended to result in weaker correlations for fluency/comprehensibility and comprehensibility/accentedness. The findings imply that having an accent does not mean being unintelligible and support prioritizing intelligible and comprehensible speech over accent reduction. The study also highlights an over-reliance on first language speaker norms in L2 pronunciation research and advocates for more transparent reporting.

Lexical proficiency is a multifaceted phenomenon that greatly impacts human judgments of writing quality. However, the importance of collocations’ contribution to proficiency assessment has received less attention than that of single words, despite collocations’ essential role in language production. This study, therefore, investigated how aspects of collocational proficiency affect the ratings that examiners give to English learner essays. To do so, collocational features related to sophistication and accuracy were manipulated in a set of argumentative essays. Examiners then rated the texts and provided rationales for their choices. The findings revealed that the use of lower-frequency words significantly and positively impacted the experts’ ratings. When used as part of collocations, such words then provided a small yet significant additional boost to ratings. Notably, there was no significant effect for increased collocational accuracy. These findings suggest that low-frequency words within collocations are particularly salient to examiners and deserving of pedagogic focus.

Research on second language (L2) speech learning suggests that incidental perception training can lead to the establishment of non-native phonological categories. The present study contributes to this line of enquiry by investigating how this training is mediated by individual differences in working memory capacity and domain-general auditory processing abilities. In our study, 130 native British English speakers without prior knowledge of Portuguese were randomly assigned to trained or untrained conditions. All participants completed a visual digit span task and an auditory processing test battery. We observed improvements from pretest to post-test in production only, but since both groups improved, these gains cannot be attributed to the incidental perception training. The analysis of the ID measures further confirms the important role played by auditory processing abilities in L2 speech learning. However, more research is needed to better understand the role of incidental perception training and the mediating role of cognitive aptitudes.

This paper explores how long-term bilingualism affects the production of intervocalic plosive consonants (/p t k b d ɡ/) in the speech of Afrikaans–Spanish bilinguals from Patagonia, Argentina. We performed sociolinguistic interviews with three speaker groups: L1-Afrikaans/L2-Spanish bilinguals (14 speakers, interviewed separately in Spanish and Afrikaans), L1-Spanish comparison speakers from Patagonia (10 speakers), and L1-Afrikaans comparison speakers from South Africa (11 speakers). We analyzed the speech data using three acoustic measures (constriction duration, relative intensity, and percent voicing) to examine the degree of lenition of the target plosives. The results demonstrate a complex interplay of factors that bring about cross-language influence, which varies based on the target phoneme and phonetic measure. Notably, the findings suggest that phenomena that are gradient phonetic processes in both languages of bilingual speakers (such as the lenition of voiceless plosives in Spanish and Afrikaans) pattern differently than phenomena that are phonological in one language but phonetic in the other (such as lenition of voiced plosives in Spanish versus Afrikaans).

Additional language speakers (ALSs) often experience anxiety due to challenges posed by their nonstandard pronunciation. Building on these insights, this paper introduces an instrument, the Accent Anxiety Scale (AAS), specifically designed to assess three sources of anxiety that are experienced by ALSs, including (a) apprehension about negative evaluations from other individuals due to their distinctive speech style, (b) concerns about rejection from the target language community because of their “foreign” pronunciation, and (c) anxieties over potential communication hurdles attributed to the intelligibility of their pronunciation. We evaluated the psychometric robustness of the AAS by analyzing data from a total of 474 immigrant and international student ALSs at a predominantly English-speaking Canadian university. Study 1 focused on immigrants (N = 203) and employed exploratory factor and correlational analyses to isolate a concise number of internally consistent and valid items for each subscale. Study 2 extended these analyses to international students (N = 153) and employed confirmatory factor and correlation analyses to further validate the AAS in this population. Study 3 examined international students (N = 118) at two time points to establish the AAS’s temporal stability. These studies yielded robust psychometric evidence for the factor structure, reliability, and validity of the AAS. The findings not only support the use of the AAS as a research instrument but also offer implications for pedagogical strategies aimed at alleviating ALSs’ accent anxiety.

This study investigated factors influencing the citations of highly cited applied linguistics research over two decades. With a pool of 302 of the top 1% most cited articles in the field, we identified 11 extrinsic factors that were independent of scientific merit but could significantly predict citation counts, including journal-related, author-related, and article-related features. Specifically, the results of multiple linear regression models showed that the time-normalized article citations were significantly predicted by the number of authors, subfield, methodology, title length, CiteScore, accessibility, and scholar h-index. The remaining factors did not exhibit any statistical significance, including the number of references, funding, internationality, and geographical origin. The combined predictive power of all these factors (R²=.208, p<.05) verifies the role of nonscientific factors contributing to high citations for applied linguistics research. These results encourage applied linguistics researchers and practitioners to recognize the underlying forces affecting research impact and highlight the need for a reward system that exclusively favors sound academic practices.

There is evidence that learning a second language (L2) can shift cognition toward that predicted for the L2 and that this effect might vary with L2 proficiency, age of acquisition, length of immersion, etc. Here we explore the previously neglected variable of language instructional conditions. Participants categorized motion events in a triads-matching task after being trained on two novel linguistic labels highlighting (in)transitivity through one of three instructional conditions. Participants who learned the relevant knowledge under a meaning-focused instructional condition (memorizing meanings of exemplar sentences) showed a higher likelihood of categorizing based on motion (in)transitivity immediately after training than a control group; those who learned under a required rule search instructional condition showed this effect only after additional practice; while those who learned through another type of form-focused instructional condition (direct metalinguistic explanation) did not show this effect even after such practice. These differences were obtained despite the fact that the three groups were matched on awareness of the target system at the level of understanding and near-perfect performance on a grammaticality judgment task. The findings are discussed in terms of the depth of processing in instructed SLA and models of language–cognition interactions.

This study conceptually replicates Cepeda, Coburn, Rohrer, Wixted, Mozer, & Pashler’s (2009, Experiment 1) study on the effects of distributed practice on second language (L2) vocabulary learning to examine its generalizability to a new context and population sample. The secondary focus of the paper is to examine the challenges and affordances of online data collection and participant recruitment sites. Both the original and our study examined the effects of distributed practice on two study sessions to learn L2 vocabulary assessed on a 10-day delayed posttest. Our results showed that the spaced conditions significantly outperformed the massed condition, mirroring the original study’s findings. However, Cepeda et al.’s (2009) participants outscored our participants by 10–20% (in each experimental group) on the posttest. While these findings highlight the benefits of spacing towards learning and memory, they also underscore the challenges researchers may face when conducting experimental research in online environments.

This study is designed to understand embarrassment in the second/foreign language (L2) context. Following a mixed-method design, in Phase 1, a sample of 141 tertiary-level Austrian English language learners were asked to write a narrative about their experiences of embarrassment in their language learning histories. Analyzing the narratives showed that L2 embarrassment is a multidimensional construct that is frequently experienced by a range of language learners. In Phase 2, we developed and validated an L2 classroom speaking embarrassment (L2CSE) scale among a sample of 402 international English language learners drawing on the literature and analysis of the narratives. Data showed that L2 embarrassment is best represented by a bifactor exploratory structural equation model, capturing both general and specific aspects of L2 embarrassment. We found that a supportive classroom environment and fostering a growth mindset can decrease the risk of L2 embarrassment. As expected, L2 embarrassment was a negative predictor of willingness to communicate and self-perceived language proficiency. These initial findings suggest that L2 embarrassment could be an important and influential emotion in the language learning classroom context which requires further research.
