The current study examined the extent to which cognitive fluency (CF) contributes to utterance fluency (UF) at the level of constructs. A total of 128 Japanese-speaking learners of English completed four speaking tasks—argumentative task, picture narrative task, reading-to-speaking task, and reading-while-listening-to-speaking task—and a battery of linguistic knowledge tests, capturing vocabulary size, lexical retrieval speed, sentence construction skills, grammaticality judgments, and articulatory speed. Their speaking performance was analyzed in terms of speed, breakdown, and repair fluency (i.e., UF), and scores on linguistic knowledge tests were used to assess students’ L2 linguistic resources and processing skills (i.e., CF). Structural equation modeling revealed a complex interplay between the multidimensionality of CF and UF and speaking task types. L2 processing speed consistently contributed to all aspects of UF across speaking tasks, whereas the role of linguistic resources in speed and repair fluency varied, depending on task characteristics.

Research into second language (L2) reading is an exponentially growing field. Yet, it still has a relatively short supply of comparable, ecologically valid data from readers representing a variety of first languages (L1). This article addresses this need by presenting a new data resource called MECO L2 (Multilingual Eye Movements Corpus), a rich behavioral eye-tracking record of text reading in English as an L2 among 543 university student speakers of 12 different L1s. MECO L2 includes a test battery of component skills of reading and allows for a comparison of the participants’ reading performance in their L1 and L2. This data resource enables innovative large-scale cross-sample analyses of predictors of L2 reading fluency and comprehension. We first introduce the design and structure of the MECO L2 resource, along with reliability estimates and basic descriptive analyses. Then, we illustrate the utility of MECO L2 by quantifying contributions of four sources to variability in L2 reading proficiency proposed in prior literature: reading fluency and comprehension in L1, proficiency in L2 component skills of reading, extralinguistic factors, and the L1 of the readers. Major findings included (a) a fundamental contrast between the determinants of L2 reading fluency versus comprehension accuracy, and (b) high within-participant consistency in the real-time strategy of reading in L1 and L2. We conclude by reviewing the implications of these findings to theories of L2 acquisition and outline further directions in which the new data resource may support L2 reading research.

This study examined how discriminability and prototypicality of nonnative phones modulate the amplitude of the Mismatch Negativity (MMN) event-related brain potential. We hypothesized that if a frequently occurring (standard) stimulus is not prototypical to a listener, a weaker predictive memory trace will be formed and a smaller MMN will be generated for a phonetic deviant, regardless of the discriminability between the standard and deviant stimuli. The MMN amplitudes of Japanese speakers hearing the English vowels /æ/ and /ɑ/ as standard stimuli and /ʌ/ as a deviant stimulus in an oddball paradigm were measured. Although the English /æ/-/ʌ/ contrast was more discriminable than the English /ɑ/-/ʌ/ contrast for Japanese speakers, when Japanese speakers heard the /æ/ standard stimulus (i.e., less prototypical as Japanese /a/) and the /ʌ/ deviant stimulus, their MMN amplitude was smaller than the one elicited when they heard /ɑ/ as a standard stimulus (i.e., more prototypical as Japanese /a/) and /ʌ/ as a deviant stimulus. The prototypicality of the standard stimuli in listeners’ phonological representations modulates the MMN amplitude more robustly than does the discriminability between standard and deviant stimuli.

This study examined whether university students perceive holds (i.e., a listener’s temporary cessation of dynamic movement) as a visual cue of nonunderstanding. Conversations between English second language (L2) university students were sampled to extract episodes of other-initiated repair through open clarification requests (e.g., what?, sorry?). Brief, silent video clips were presented to 60 raters across two experiments who assessed the listener’s comprehension, which was their perception about how well the listener had understood the speaker. Experiment 1 tested whether raters can differentiate between the onset and release of listener holds while Experiment 2 examined whether they are sensitive to the sequential organization of holds. Results indicated that raters clearly differentiated between hold onsets and releases and were sensitive to the temporal position of holds in the entire repair sequence. Taken together, these findings suggest that holds are a reliable signal of nonunderstanding with potential implications for L2 teaching and assessment.

In comparative studies focusing on context of learning, the main contexts under investigation have been study abroad (SA), at-home formal instruction (AH), and domestic immersion (IM). With the global status of English and its burgeoning popularity as a medium of instruction in countries where English only holds the status of a lingua franca, a new SA context has emerged. This study compares the L2 learning of English in this new English as a lingua franca study abroad (ELFSA) context to Anglophone SA and AH in terms of oral and written complexity, accuracy, and fluency gains. Participants’ perceptions of contextual differences concerning the amount of language contact, use, development, and their views toward English are also explored qualitatively. Apart from indicating equal development on most CAF measures after a semester, the qualitative findings highlight ELFSA as providing a low-anxiety atmosphere that helps sojourners gain ownership of English. Thus, ELFSA emerges as an appealing study abroad context for future sojourners.

This study offers methodological synergy in the examination of factorial structure in second language (L2) research. It illustrates the effectiveness and flexibility of the recently developed exploratory structural equation modeling (ESEM) method, which integrates the advantages of exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) into one complete measurement model. Two sets of data were collected using the L2 Passion Scale, which measures a dualistic model of passion. Study 1 participants were 220 L2 students. A comparison was made between the CFA and the ESEM models. The results demonstrated the superiority of the ESEM method relative to CFA in terms of better goodness-of-fit indices and realistic correlated factors. These results were replicated in another sample of 272 L2 students, providing support for the predictive validity using a structural ESEM model. Guidelines are provided and Mplus syntax files (codes) are included to help analysts apply the methods. We also make the data available publicly. Overall, this research demonstrated the usefulness of ESEM for examining the construct, discriminant, and convergent validity of L2 scales over CFA.

A foundation of second language motivational theory has been that motivation contributes to explaining variance in language learning proficiency; however, empirical findings have been mixed. This article presents an innovative approach to exploring L2 proficiency and motivations of teenage English language learners in Madrid, Spain (N = 1773). Participants completed a multiskill English language test, plus an eight-scale questionnaire operationalizing constructs from Dörnyei’s L2 Motivational Self System (Dörnyei, 2005). Data were analysed using Latent Variable Mixture Modeling, a person-centered profiling approach. Results indicated five distinct classes of students, characterized by differing motivation-proficiency profiles. The importance of this study is that the analysis does not assume a homogenous relationship between motivational traits and proficiency levels across the learner sample; whilst there is undoubtedly a connection between the two areas, it is not a straightforward correlation, explaining to some extent discrepancies in previous findings and laying groundwork for further, more nuanced, investigation.

Replication is a research methodology designed to verify, consolidate, and generalize knowledge and understanding within empirical fields of study. In second language studies, however, reviews share widespread concern about the infrequency of replication. A common but speculative explanation for this situation is that replication studies are not valued because they lack originality and/or innovation. To better understand and respond to the infrequency of replication in our field, 354 researchers were surveyed about their attitudes toward replication and their practices conducting replication studies. Responses included worldwide participation from researchers with and without replication experience. Overall, replications were evaluated as relevant and valuable to the field. Claims that replication studies lack originality/innovation were not supported. However, dissemination issues were identified: half of published replication studies lacked explicit labeling and one quarter of completed replications were unpublished. Explicit labeling of replication studies and training in research methodology and dissemination can address this situation.

The present study uses event-related potentials (ERPs) to examine nonlocal agreement processing between native (L1) English speakers and Chinese–English second language (L2) learners, whose L1 lacks number agreement. We manipulated number marking with determiners (the vs. that/these) to see how determiner-specification influences both native and nonnative processing downstream for verbal number agreement. Behavioral and ERP results suggest both groups detected nonlocal agreement violations, indexed by a P600 effect. Moreover, the manipulation of determiner-number specification revealed a facilitation effect across the board in both grammaticality judgment and ERP responses for both groups: increased judgment accuracy and a larger P600 effect amplitude for sentences containing violations with demonstratives rather than bare determiners. Contrary to some claims regarding the potential for nonnative processing, the present data suggest that L1 and L2 speakers show similar ERP responses when processing agreement, even when the L1 lacks the relevant distinction.

This study takes a mixed-methods approach to explore the influence of emotion-laden (positive vs. negative vs. neutral) texts and words on vocabulary learning for Spanish heritage and foreign language learners. Participants (N = 121) were tasked with learning emotion-laden pseudowords embedded in three emotion-laden texts centered around themes of bilingualism, immigration, and identity. Form recognition, translation, and multiple-choice tests were designed to measure vocabulary recall and retention. Results from a mixed-effects modeling analysis showed that the neutral and negative emotion-laden texts predicted better vocabulary learning outcomes than the positive text for both HLLs and FLLs and that neutral words were learned best by all learners. Qualitative findings from open-ended questionnaires suggest emotional arousal as another influential affective factor in vocabulary learning for learners of diverse sociolinguistic backgrounds. Directions for future emotions research in SLA and pedagogical implications of socially relevant, emotion-laden material for vocabulary learning are discussed.

There is currently much interest in the role of prediction in language processing, both in L1 and L2. For language acquisition researchers, this has prompted debate on the role that predictive processing may play in both L1 and L2 language learning, if any. In this conceptual review, we explore the role of prediction and prediction error as a potential learning aid. We examine different proposed prediction mechanisms and the empirical evidence for them, alongside the factors constraining prediction for both L1 and L2 speakers. We then review the evidence on the role of prediction in learning languages. We report computational modeling that underpins a number of proposals on the role of prediction in L1 and L2 learning, then lay out the empirical evidence supporting the predictions made by modeling, from research into priming and adaptation. Finally, we point out the limitations of these mechanisms in both L1 and L2 speakers.

The present meta-analysis aimed to improve on Involvement Load Hypothesis (ILH) by incorporating it into a broader framework that predicts incidental vocabulary learning. Studies testing the ILH were systematically collected and 42 studies meeting our inclusion criteria were analyzed. The model-selection approach was used to determine the optimal statistical model (i.e., a set of predictor variables) that best predicts learning gains. Following previous findings, we investigated whether the prediction of the ILH improved by (a) examining the influence of each level of individual ILH components (need, search, and evaluation), (b) adopting optimal operationalization of the ILH components and test format grouping, and (c) including other empirically motivated variables. Results showed that the resulting models explained a greater variance in learning gains. Based on the models, we created incidental vocabulary learning formulas. Using these formulas, one can calculate the effectiveness index of activities to predict their relative effectiveness more accurately on incidental vocabulary learning.

Previous research has shown that orthographic marking may have a function beyond identifying orthographic word forms. In two visual priming experiments with native speakers and advanced learners of German (Czech natives) we tested the hypothesis that orthography can convey word-class cues comparable to morphological marking. We examined the effect of initial letter capitalization of nouns (a specific property of German orthography) on the processing of five homonymous and grammatically ambiguous forms. Both populations showed the same pattern of results: deverbal nouns (conversions) patterned together with countable nouns while in a previous study (with eliminated orthographic word-class cues) they patterned together with infinitives. Together, findings suggest that orthographic cues can trigger word-class-specific lexical retrieval/access. They also suggest a lexical entry structure in which conversion nouns, infinitives, and inflected verbal forms share a category-neutral parent node and that specified subnodes are accessed only when specifying cues are available and/or necessary for processing.

A quarter of a century has passed since complex dynamic systems theory was proposed as an alternative paradigm to rethink and reexamine some of the main questions and phenomena in applied linguistics and language learning. In this article, we report a scoping review of the heterogenous body of research adopting this framework. We analyzed 158 reports satisfying our inclusion criteria (89 journal articles and 69 dissertations) for methodological characteristics and substantive contributions. We first highlight methodological trends in the report pool using a framework for dynamic method integration at the levels of study aim, unit of analysis, and choice of method. We then survey the main substantive contribution this body of research has made to the field. Finally, examination of study quality in these reports revealed a number of potential areas of improvement. We synthesize these insights in what we call the “nine tenets” of complex dynamic systems theory research, which we hope will help enhance the methodological rigor and the substantive contribution of future research.

Academic lectures are potential sources of vocabulary learning for second language learners studying at universities where English is the medium of instruction, as well as those in English for Academic Purposes (EAP) programs. Topic-related vocabulary is likely to occur frequently in academic texts, and academic speech consists of a reasonable proportion of frequently occurring sequences of words. Yet no intervention studies have explored the potential for learning single words and collocations through viewing a video of an unmodified academic lecture. To address this gap, this study collected data from 55 EAP learners in China, following a pretest-posttest design. The experimental group (n = 28) watched a video of an academic lecture in which 50 target single words and 19 target collocations were presented while the control group (n = 27) received no treatment. Results show that viewing the lecture led to significant learning gains of single words at the meaning recall level and collocations at the form recognition level. Frequency of occurrence in the lecture appeared to significantly contribute to the learning of single words but not the learning of collocations. Prior knowledge of general vocabulary appeared to make no significant contribution to the learning of single words and collocations.

In two studies, we examined two functional dimensions of L2 learners’ self-regulation toward their motivational goals: assessment and locomotion. The assessment constitutes the aspect of self-regulation concerned with critically evaluating the relative quality of L2 states and goals and the means to achieve them. The locomotion mode constitutes the aspect of self-regulation concerned with uninterrupted movement from state to state toward L2 goals. We developed two scales to measure L2 self-regulatory modes. We also examined how L2 learners’ regulatory modes were associated with their emotional experiences, motivation, and language proficiency. Psychometric work attested to the reliability and validity of the two scales. Moreover, regression analyses revealed that each L2 self-regulatory mode has distinct emotional, motivational, and linguistic emphases. Finally, cluster analyses suggested that both L2 self-regulatory modes should work together for optimal L2 learning outcomes.

The relationship between working memory (WM) and second-language (L2) reading has been extensively examined, with mixed results. Our meta-analysis models the potential impact of underresearched variables considered to moderate this relationship. Results from 74 studies (228 correlations) showed a significant, small relationship between WM and L2 reading (r = .300). Of the eight moderators examined, the WM–L2 reading relationship differed between studies using first-language (L1) and L2 WM tasks and between studies reporting and not reporting WM task reliability. Methodological features of reading comprehension measures or learners’ proficiency did not moderate the relationship. These results suggest that measurement practices of WM—rather than L2 reading measures or learner characteristics—matter in understanding the WM–L2 reading relationship. Implications and future directions are discussed.

The primary aim of this study was to investigate prosodic prominence across three groups of Sylheti-English bilinguals: first-generation who arrived as adults, first-generation who arrived as children, and second-generation, i.e., born in the United Kingdom to parents who grew up in Bangladesh. To measure prominence, f0, duration, and intensity were measured across disyllabic words in Sylheti and English. The results showed significant differences in the f0 analysis. Regarding monolinguals, Sylheti prominence displayed a rising contour, in contrast to the English falling contour. In Sylheti, the bilinguals born in the United Kingdom were the only group significantly different from the Sylheti monolinguals, displaying an English-like falling pattern in their Sylheti prominence. In English, the late arrival bilinguals displayed a Sylheti-like prominence realization, but the early arrivals and those born in the United Kingdom approximated the monolingual English prominence realization. Overall, language use patterns were the most significant factor related to the bilinguals’ prominence realization.

To examine the effects of task repetition with different schedules, English-as-a-foreign-language classroom learners performed the same oral narrative task six times under three different schedules. They narrated the same six-frame cartoon story (a) six times consecutively in one class (massed practice), (b) three times at the beginning and at the end of a class (short-spaced practice), and (c) three times as a part of two classes 1 week apart (long-spaced practice). The results yielded by an immediate posttest using a novel cartoon showed that massed practice reduced breakdown fluency (mid-clause and clause-final pauses) the most. However, the participants in the massed-practice group showed degraded speed (slower articulation rate) and repair fluency (more verbatim repetition). The effects of repetition schedule seem limited on a 1-week delayed posttest involving a novel cartoon. Yet, when participants narrated the same practiced cartoon 1 week later, massed practice also resulted in more verbatim repetition.
