Systematic review synthesising the effects of study abroad experience on the development of language fluency

ABSTRACT Given the importance of learning contexts in second language (L2) learning, study abroad (SA) has received due attention in the L2 literature, as this context has been proposed to accelerate L2 development. In line with recent efforts to synthesise the effects of SA on L2 learning, the present study reports a meta-analysis of the effects of SA experience on the development of L2 fluency compared to the at-home environment. Our dataset comprised 14 between-group studies, all based on quasi-experimental designs, including a comparison group. The results indicate that the SA context had an overall medium effect (Hedges’ g = 0.65, SE = 0.10, 95% CI [0.44, 0.87]) on the development of L2 fluency compared to its at-home counterpart. We also identified several variables related to learner characteristics and SA programme features and further examined their moderating effects on SA. Based on our findings, an in-depth discussion of how these variables are related to the effectiveness of SA was provided, and recommendations for L2 learners and SA researchers involved in SA programmes were proposed.

Cognitive Fluency in L2: The Effect of Automatic and Controlled Lexical Processing on Speech Rate

The fluency of second language (L2) speech can be influenced by L2 proficiency, but also by differences in the efficiency of cognitive operations and personal speaking styles. The nature of cognitive fluency is still, however, little understood. Therefore, we studied the cognitive fluency of Finnish advanced students of English (N = 64) to understand how the efficiency of cognitive processing influences speech rate. Cognitive fluency was operationalised as automaticity of lexical access (measured by rapid word recognition) and attention control (measured by the Stroop task). The tasks were conducted in both L1 (Finnish) and L2 (English) to examine the (dis)similarity of processing in the two languages. Speech rate in a monologue task was used as the dependent measure of speaking performance. The results showed that after controlling for the L1 speech rate and L1 cognitive fluency, the L2 attention control measures explained a small amount of additional variance in L2 speech rate. These results are discussed in relation to the cognitive fluency framework and general speaking proficiency research.

How is L2 pair interaction related to fluency and language use? A quantitative approach

Previous research examined L2 interaction by describing salient features exhibited in different patterns of peer interaction. These studies mostly used qualitative methods and focused on the collaborative aspect of such construct (Galaczi, 2008). The present study adopts a quantitative approach to explore and describe L2 interaction, utilizing the data of the Corpus of Collaborative Oral Tasks (CCOT). Specifically, it measures pairs’ interaction by creating a composite score of interactivity to understand the relationship between the dyads' degree of interactivity and their use of lexico-grammatical features as well as their L2 fluency. Pearson's correlation tests showed weak to moderate positive relationships between interactivity and discourse particles, response forms, wh-questions, and second person pronouns. Additionally, the tests revealed weak negative relationships between interactivity and both nominal forms and hesitations. Furthermore, revealing moderate relationships, Pearson's correlation tests showed that interactivity was associated with more fluent L2 speech, where learners of higher interactivity levels tended to produce fewer silent pauses and faster speech rates. The study provides insights for scholars interested in L2 interaction. It suggests that some linguistic features were not only associated with collaborative behaviors (as reported in the literature) but also with interactivity as broad aspect. Furthermore, it provides a description of how the act of turn taking might potentially serve the fluency of higher interactivity students, warranting further investigation of turn frequency among L2 test takers as test raters might potentially be influenced by the test candidates’ fluency. Finally, it reports that L2 interactivity exhibited a relationship pattern with linguistic features that resembles patterns reported in the literature of studies on native speakers of English.

Cognitive Control Performance as Measured by Clustering and Switching in Nepali – English Bilingual Verbal Fluency Task

Verbal fluency task is a simple yet powerful neuropsychological tool for measuring linguistic and cognitive processing. In this research article we report the clustering and switching, as identified by Troyer and colleagues (1997), as cognitive control measured through semantic and phonetic verbal fluency task. We tested 25 Nepali (L1) - English (L2) bilingual adults with mean age of 22 years on f, a, s for English phonemic fluency, s, k, d for Nepali phonetic fluency and animals, cloths, vegetables, fruits and flowers for semantic fluency in both Nepali and English. The participants performed better in L2 phonetic fluency compared to L1 phonetic fluency, whereas, there was mixed results in semantic output in both the languages. They exhibited more clusters in phonetic fluency compared to semantic fluency in both L1 and L2 which indicates participants needed to disengage from the previous strategy or subcategory and move on to the next strategy or subcategory, thus, reflecting more cognitive demand imposed by the phonetic fluency compared to semantic fluency. This is the first such study with Nepali – English bilinguals. This study may further be extended to include more diversified population in terms of age, language family, typicality and ethnicity as independent variables.

The role of differential cross-linguistic influence and other constraints in predictive L2 gender processing

Previous studies on the use of morphosyntactic gender cues for linguistic prediction show that non-native speakers’ use of grammatical gender information is influenced by various factors. In the present study, we examined the influence of differential cross-linguistic influence (DCLI), knowledge of L2 lexical gender, gender congruency, and L2 fluency. To this end, we investigated L1 Oromo L2 Amharic speakers as well as L1 Amharic speakers, using the Visual World Paradigm (VWP) and supplementary offline experiments. We investigated two groups of L2 Amharic speakers, i.e., L1 Eastern Oromo L2 Amharic and L1 Western Oromo L2 Amharic speakers. The Eastern Oromo dialect patterns with Amharic in terms of gender agreement unlike the Western Oromo dialect which does not have grammatical gender. Analyses of the participants’ proportion of eye fixations show that early exposure to the gendered Eastern Oromo dialect facilitates predictive L2 gender processing. L2 fluency, the speakers’ knowledge of L2 lexical gender, and specific properties of the gender cues modulate predictive L2 gender processing. However, there is no significant influence of lexical gender congruency. The study has ecological significance as it presents empirical data from understudied languages.

Listener perceptions of L1 speech in L2 and L3 fluency assessment contexts: a qualitative approach

Studies on listeners’ perceptions of speech fluency have typically focused on numeric L2 fluency assessments and rarely addressed individual differences in L1 speech fluency qualitatively. The objective of the present study was to examine how listeners attend to speakers’ L1 speech when assessing the speakers’ L2 and L3 fluency. In the study, 37 listeners were presented with freely produced L1 Finnish, L2 English (Experiment I), and L3 Swedish (Experiment II) speech by Finnish-speaking and Finnish–Swedish bilingual speakers (N=30). The listeners first listened to the speakers’ L1 Finnish speech before assessing their target language fluency and then commented on how hearing the L1 speech samples affected their ratings. A qualitative analysis focusing on the listeners’ comments revealed that listeners attend to both temporal and non-fluency related features in L1 speech when assessing target language fluency, but there were clear individual differences across listeners’ intuitive approaches to L1 speech.

Replication research in the domain of perceived L2 fluency: Approximate and close replications of Kormos and Dénes (2004) and Rossiter (2009)

Abstract The primary objective of this paper is to contribute to the advancement of second language (L2) fluency research by outlining a specific proposal for future replication studies. The overarching goal is to assess the generalisability of the original findings of the two influential studies in the area of perceived fluency: Kormos and Dénes (2004) and Rossiter (2009). This objective will be achieved by first introducing the concept of L2 fluency that often conflates two categories: (1) overall language proficiency; (2) temporal features of speech production. The paper then highlights limitations in the current fluency research paradigm emphasising the variability in the methods employed for speech analysis and rating data collection. This diversity makes it somewhat challenging to compare results across various studies. In response to these challenges, the second part of the paper proposes several close and approximate replications of the two studies.

The effects of distributed practice on second language fluency development

Abstract This study examined the effects of distributed practice on second language (L2) speech fluency development. A total of 116 Japanese L2 learners of English were randomly divided into experimental or control conditions. Learners assigned to the experimental groups engaged in four fluency training sessions either in a short-spaced (1-day interval) or long-spaced (7-day interval) condition. Although different learning trajectories were observed during the training phase, the posttests conducted 7 and 28 days after the training showed similar fluency gains for the two groups, indicating that short- and long-spaced conditions were equally effective for developing L2 fluency. The current study extends the line of research in distributed practice and task repetition for L2 fluency development.

The moderating role of L2 proficiency in the predictive power of L1 fluency on L2 utterance fluency

The current study examined the extent to which first language (L1) utterance fluency measures can predict second language (L2) fluency and how L2 proficiency moderates the relationship between L1 and L2 fluency. A total of 104 Japanese-speaking learners of English completed different argumentative speech tasks in their L1 and L2. Their speaking performance was analysed using measures of speed, breakdown, and repair fluency. L2 proficiency was operationalised as cognitive fluency. Two factor scores of cognitive fluency—linguistic resources and processing speed—were computed based on performance in a set of linguistic knowledge tests capturing vocabulary knowledge, morphosyntactic processing, and articulatory skills. A series of generalised linear mixed-effects models revealed small-to-moderate effect sizes for the predictive power of L1 utterance fluency measures on their L2 counterparts. Moderator effects of L2 proficiency were found only in speed fluency measures. The relationship between L1 and L2 speed fluency was weaker for L2 learners with wider L2 linguistic resources. Conversely, for those with faster L2 processing speed, the L1-L2 link tended to be stronger. These findings indicate that the L1-L2 fluency link is subject to the complex interplay of phonological differences between learners’ L1 and L2 and their L2 proficiency, offering implications for diagnostic speaking assessment.

Investigating the Correlation between English Spoken Fluency and Working Memory Capacity in both Dialogic and Monologic Presentations

Studies on second language (L2) speech fluency recommend studying fluency in a dialogic context. In response to the researchers' calls, this study introduced monologic and dialogic tasks to investigate the various aspects of speed, breakdown, and repair fluency in the oral performancemost L2 fluency studies have looked at oral fluency in a monologic task. Dialogue is the more authentic and natural way of communication, which is apparent in everyday language use. Currently, there is a scarcity of research examining dialogue fluency in non-native bilingual speakers who share the same L2. The existing body of research on language learning and processing has underscored significant connections between individual differences (IDs) in working memory capacity (WMC) and models of L2 speech production in both first language (L1). Nevertheless, it remains unclear whether variations in WMC are linked to dysfluency in L2 monologue and dialogue. Therefore, this study also aimed to fill this gap in the literature by investigating the correlation between utterance fluency in both monologue and dialogue and WMC. A total of 64 undergraduate Saudi students were given various tasks as part of the study. An argumentative task was presented as a monologue focused on a prevalent topic in the participants’ country. In contrast, during a dialogic discussion task, 32 pairs engaged in exchanging opinions on a popular subject in their country. Additionally, participants underwent two challenging working memory (WM) tests: the Operation Span Test and the Backward Digit Span Test. The findings aligned with prior research, indicating that L2 participants demonstrated greater fluency in dialogue compared to monologue, as evident in speed and breakdown measures of utterance fluency. Interestingly, WMC did not emerge as a robust predictor for variations in L2 oral performances between monologue and dialogue.

Speech Fluency Production and Perception in L1 (Slovak) and L2 (English) Read Speech.

Research on fluency in native (L1) and non-native (L2) speech production and perception helps us understand how individual L1 speaking style might affect perceived L2 fluency and how this relationship might be reflected in L1 versus L2 oral assessment. While the relationship between production and perception of fluency in spontaneous speech has been studied, the information provided by reading has been overlooked. We argue that reading provides a direct and controlled way to assess language proficiency that might complement information gained from spontaneous speaking. This work analyzes the relationship between speech fluency production and perception in passages of L1 (Slovak) and L2 (English) read by 57 undergraduate Slovak students of English and rated for fluency by 15 English teachers who are Slovak natives. We compare acoustic production measures between L1 and L2 and analyze how their effect on perceived fluency differs for the two languages. Our main finding is that the articulation rate, the overall number of pauses, and the number of between-clause and mid-clause pauses predict ratings differently in L1 Slovak versus L2 English. The speech rate and durations of pauses predict ratings similarly in both languages. The contribution of our results to understanding fluency aspects of spontaneous and read speech, the relationship between L1 and L2, the relationship between production and perception, and to the teaching of L2 English are discussed.

Embracing bilingualism: L1 retention amidst L2 acquisition

ABSTRACT In L1 attrition research, it's recognized that a previously acquired language can transform under the influence of a newly acquired one. However, the precise L1-L2 relationship is intricate and warrants further study. Some research suggest that L2 mastery might reduce L1 proficiency, while others show that both languages can be maintained. Age of onset and L1 use are the factors that have been discussed in the debate surrounding L1 attrition. The study aims to contribute to the ongoing discussion by examining L1 and L2 proficiency of Russian-English bilingual speakers (N = 35). The participants with comparable L2 proficiency but various degrees of L1 attrition who arrived at different ages and differed in their frequency of L1 use were recruited for the study. This diverse group provided an ideal quality sample for investigating the role of age of onset and L1 use, as well as the interplay between L1 and L2. By comparing L1 and L2 lexical diversity, syntactic complexity, and fluency, the study revealed that higher L2 proficiency was not associated with lower levels of L1 proficiency, suggesting that L1 retention is possible amidst L2 acquisition. L1 use played a more significant role in the L1 maintenance of these bilingual individuals.

Two Languages in One Mind: Biliteracy, Speech Connectedness and Reading in 5th Grade Bilingual Children

This study examined the effects of bilingual education and simultaneous biliteracy on children’s levels of speech connectedness and reading in Portuguese and English. Thirty-two 5th graders completed oral production tasks and took reading fluency and comprehension tests in L1 and L2. Our results show that, in general, children show connectedness and reading scores which are correlated in the two languages, that is, the languages follow different, but related paths in the time point they were assessed. We conclude that simultaneous biliteracy, in the case of the participants of this research, is not detrimental to the outcomes of either language. On the contrary, it promotes the concomitant use of languages, which, in turn, seems to guarantee support for both languages, L1 and L2, in a bidirectional fashion.

Impact of Bilingualism on Emotion Perception

Bilingualism can affect people’s emotion perception and cognition. By assigning emotion priming tasks, emotion recognizing ability of bilingual people can be compared to monolingual people to indicate the difference of language dominance of the two populations. In our study, it is hypothesized that learning a second language can cause a shift of language dominance from the mother language (Chinese) to the second language (English). Also, we propose that bilingual speaker with a higher fluency or extrovert personalities in L2 will develop more ability in perceiving emotions in the second language. Moreover, defamiliarization of first language can also happen while switching language dominance.

Fluency in Speaking as a Dynamic Construct

In current research into second language (L2) speaking, aspects of fluency are measured as static constructs. Averaged over a complete speaking performance, for instance, syllables per minute is calculated. Similarly, the number of pauses is calculated per minute, averaged over a complete speaking task. This paper argues, however, that we need to investigate fluency as a dynamic construct. Research into L1 speaking has shown that L1 fluency aspects may show cyclical temporal patterns (Roberts & Kirsner, 2000). In addition, research into the changes in perception of L2 comprehensibility during task performance has shown that L2 comprehensibility may show dynamic patterns, with implications for ratings on comprehensibility (Nagle et al., 2019). This paper, therefore, argues that L2 fluency should be investigated as a dynamic construct as well. The paper finishes by sketching pedagogical implications and directions for future research.

The Impact of Filipina Domestic Workers on Hong Kong Primary School Children’s L2 English Spoken CAF and Reading Accuracy and Fluency

Abstract This study investigates the impact of Filipina domestic workers (FilDWs), a marginalized group in Hong Kong (HK), on HK children’s language development. It focusses on FilDWs’ influence on the second language (L2) English of bilingual HK primary school children attending an English Medium of Instruction school. The elements investigated are L2 English spoken complexity, accuracy, and fluency (CAF), and reading accuracy and fluency. Participants comprise 34 children (17 boys and 17 girls, mean age 8;11) from homes with FilDWs and 30 (15 boys and 15 girls, mean age 8;11) from homes with no FilDW. Participants completed an English reading and speaking task, and an English working memory capacity (WMC) test. Participants from households with FilDWs scored significantly higher on all aspects of both English language measures, while no significant differences for WMC were observed. These suggest that FilDWs exert a positive impact on children’s L2 English proficiency, placing them in a different position to the low status they are usually ascribed. These findings have implications for decolonizing and decentring language learning and teaching.

The Effects of Task Repetition Schedules on L2 Fluency Enhancement

This article explores the effects of different task repetition schedules on English learners’ oral fluency in terms of speed, breakdown, and repair indices using a PRAAT script to enhance objectivity and consistency in the assessment of learner performances. A total of 90 freshmen participated in the experiment and were divided into three groups: the blocked repetition group, the interleaved repetition group, and a control group. This study adopted a pre- and post-test design. After the learners repetitively practiced the problem-solving tasks for three weeks, their improvement was measured by a new task of the same type. The analyses of speed, breakdown, and repair in learners’ oral performance reported that the experimental groups outperformed the control group in fluency measurement. Specifically, the interleaved repetition group was advantageous compared with the blocked repetition group, except for the silent pause numbers. The findings not only support the interleaving effects and enrich the line of task repetition research but also have pedagogical implications in that introducing interleaved practice in real classrooms is beneficial to L2 speaking enhancement.

The role of pragmatic markers in perceptions of L2 fluency in dialogue

This matched-guise study helps identify the features of interaction that contribute to perceptions of fluency in L2 dialogue. We focus on pragmatic markers (PM) that occur frequently in L1 interaction but relatively less so in L2 English learners' speech (Fung & Carter, 2007), namely, interpersonal (e.g., I see, okay) and cognitive PMs (e.g., I mean, well, I think). Despite evidence of their functional value in interaction (McCarthy, 2009), they are often considered markers of disfluency and rarely introduced in L2 classrooms. Speech samples of highly proficient L2 interaction were digitally manipulated to control for interpersonal and cognitive PMs simulating expert speaker-like PM use. L1 and L2 English listeners (N = 231) rated and commented upon interlocutor's fluency. The quantitative results suggest that listeners generally perceived speakers as more fluent when using PMs, although the magnitude of the effect was relatively small and driven by L1 raters. Raters' qualitative comments suggest covert influence of PM use on fluency perceptions and uncovered a bias favoring English L1 speaker PM use. Results support the potential value of explicitly addressing PMs in teaching L2 fluency and help researchers in understanding the construct of spoken fluency in dialogue to guide in its measurement and assessment.

Frequent native language use supports phonemic and semantic verbal fluency in L1 and L2: An extended analysis of verbal fluency task performance in an L1 language attrition population

Purpose: Verbal fluency (VF) tasks are an efficient tool for exploring lexical retrieval. Attriters generally produce fewer words in semantic categories than monolinguals, but the processes underlying attriters’ lexical retrieval remain unclear. Phonemic tasks are scarcely applied in language attrition studies. We aim to identify processes underlying attriters’ phonemic verbal fluency (PVF) and semantic verbal fluency (SVF) performance by extending the analysis beyond total scores in the first (L1) and second (L2) language. Design: We modeled total scores and temporal aspects of task performance in L1 and L2 for the attriters, with L1 use and length of residence (LoR) as predictors. We analyzed the number and types of errors between languages and compared L1 task performance with a matched monolingual group. Data and analysis: Attriters’ ( N = 38) phonemic and semantic task performance in L1 (Finnish) and L2 (English) were modeled, and results were contrasted to a matched monolingual control group ( N = 50). Findings: Attriters demonstrated strong proficiency in L1 and similar lexical retrieval processes in L1 and L2 after 20 years of immersive L2 exposure. Frequent L1 use supported overall performance but slowed performance down in both languages. Compared with monolinguals, attriters show a disadvantage in SVF, but not due to slower initiation. Instead, attriters rely more on rapid L1 retrieval than monolinguals. Originality: Prior research on VF tasks in language attrition populations has mainly focused on SVF total scores in L1. Our investigation explores underlying mechanisms of L1 and L2 task performance in PVF and SVF within a language attrition population and contrasts L1 performance to a matched monolingual group performance. Implications: This study demonstrates the importance of investigating L2 alongside L1 in language attrition studies for a holistic approach to language processing strategies. Our findings enhance understanding of the processes underlying VF task performance, emphasizing the significance of VF task early-stage performance.
