This study aimed to closely replicate Wiseheart et al. (Bilingualism: Language and Cognition, 19(1), 141–146, 2016) by investigating the transferability of language-switching skills to nonlinguistic task switching. Current evidence is mixed and there is a need to conduct robust replications in this area. Bilingual (n = 31) and monolingual (n = 47) young adults characterized stimuli by either colour or shape based on a given cue. Modifications include online data collection (as opposed to in-person) and adapting the nonverbal intelligence test used. All other aspects of the study mirror those by Wiseheart et al. Results indicate that the bilinguals exhibited better cognitive flexibility in task switching, as evidenced by a reduced global switch cost compared with monolinguals. In contrast, mixed evidence was found for local switch costs. Findings mirror those reported by Wiseheart et al. and suggest that by employing comparable task-switch paradigms and recruiting samples matched on several key variables, including age, gender, variety of languages spoken, and use of English, bilingualism does seem to confer broader executive function advantages. Findings are discussed in relation to theoretical implications to inform future replication studies and advance the bilingual advantage in the switching debate.

Research on mobile-assisted language learning (MALL) has revealed that high rates of attrition among users can undermine the potential benefits of this learning method. To explore this issue, we surveyed 3,670 adult MALL users based on the Unified Theory of Acceptance and Use of Technology (UTAUT) and also conducted an in-depth analysis of their historical app usage data. The results of hierarchical k-means cluster analysis and recurrent event survival analysis revealed three major findings. First, three distinct profiles of learners were characterized by different MALL acceptance and engagement experiences. Second, those with greater MALL acceptance displayed more intense, frequent, and durable app usage (behavioral engagement). Lastly, high levels of MALL acceptance were associated with more frequent pauses in app usage but also (a) longer active usage, (b) shorter breaks before returning to the app, and, ultimately, (c) fewer dropouts. We argue that persistence is a multidimensional process involving cyclical phases of engagement, disengagement, dormancy, and reengagement, with each aspect, like intensity, frequency, and duration, building up cumulatively over time. Implications for promoting persistent MALL engagement are discussed.

This study examined the role of discourse organization in second language (L2) comprehensibility ratings. Twelve English for Academic Purposes teachers listened to 60 L2 speech samples elicited through a TOEFL–type integrated speaking task, evaluating each sample for comprehensibility and coherence (perceived interconnectedness of ideas). The samples were analyzed for the occurrence of discourse features at micro and macro levels. Results revealed a strong association between coherence and comprehensibility (r = .70). Whereas L2 speakers’ use of additive connectives (e.g., and) uniquely predicted comprehensibility, ordering of ideas and source–speech similarity in speakers’ performances predicted coherence. Lexical overlaps predicted both constructs. Findings underscore the importance of coherence to comprehensible academic L2 speech demonstrating that the two constructs include partially overlapping yet distinct characteristics.

The study aimed to examine the interrelationships between growth mindset, L2 aptitude, L2 grit, and L2 achievement, while also exploring the moderating role of gender in these interactions. A sample of 236 English-major students participated in the study by completing a language aptitude test and a questionnaire. The results of path analyses indicated that both aptitude and L2 grit similarly and positively predicted L2 achievement. The growth mindset had no direct effect on L2 achievement, whereas its indirect effects reached statistical significance. Moreover, growth mindset and L2 grit were found to be unrelated to L2 aptitude. Although female and male students did not differ significantly in their growth mindset, L2 aptitude, L2 grit, and L2 achievement scores, Multi-Group Path Analyses unveiled subtle gender differences.

This study was an approximate replication of Rothman (2011),examining the determiner phrase syntax of a large sample (n = 211) of L3 learners of Portuguese who spoke English and Spanish. Rothman (2011) investigated whether L3 Italian or Brazilian Portuguese speakers are differently impacted by another known Romance Language, if it was their L1 or L2. The original study concluded that groups did not perform differently on experimental tasks on the basis of a null effect, and that the typological similarity of Spanish, Portuguese, or Italian predicts transfer in the initial stages of L3 acquisition. The present replication recreated all materials, which were unavailable, and examined the same population and questions. However, rather than examining L3 Italian and L3 Brazilian Portuguese, the present work maintained a constant L3 Portuguese. Learners were divided into two groups in a mirror-image design (n = 96 L1 English-L2 Spanish, n = 115 L1 Spanish-L2 English), and data were collected online. Like the original study, there was no main effect of group in any of the two-way analyses of variance. However, results show that it should not be assumed that experimental groups behave equivalently based on a null effect: Of the four total post hoc tests of equivalence, only two were significant when the equivalence bounds were set at a small effect size (d = $ pm $ .4). Ultimately, it is argued that determining the smallest effect size of interest and subsequent equivalence testing are necessary to answer key questions in the field of L3 acquisition.

Most words in a language have more than one meaning. Yet, few studies have explicitly examined the acquisition of secondary meanings of L2 words and the extent to which polysemy and homonymy affect vocabulary learning. This study explores the effect of polysemy and homonymy on the deliberate acquisition of the form–meaning connections of L2 words. Thirty-six EFL learners (compared with a control group of 30) learned secondary polysemous and homonymous meanings of familiar words and primary meanings of unfamiliar words using flashcards. Knowledge of target words was measured using meaning–recall and meaning–recognition tests immediately after the treatment and again one week later. The findings indicated that learning another meaning for a familiar word was just as difficult as learning the primary meaning of an unfamiliar word, suggesting that the type of meaning (primary, secondary polysemous, or secondary homonymous) might not be an influencing factor in the deliberate acquisition of L2 words.

This study investigates whether second language (L2) learners’ language development and accuracy in production are comparable across oral and written modalities on the basis of Pienemann’s processability theory (PT). Eighty-seven English as a Foreign Language (EFL) learners, from high beginner to advanced levels, completed comparable speaking and writing tasks designed to elicit particular morphosyntactic structures predicted by PT to correspond to L2 stages of development. Time constraints encouraged participants to respond spontaneously, thus drawing on implicit knowledge. Implicational scaling shows correlations that suggest comparable language development between the modalities. However, accuracy was higher earlier in the written than in the oral modality, and accuracy in the written modality was more stable. The results provide a clearer understanding of the similarities and differences of L2 oral and written development and demonstrate that PT can be applied to L2 writing.

Manual production enhances learning and recall of signs by hearing second language learners; however, the mechanisms enabling this effect are unclear. We examined whether the motor encoding (somatosensory feedback) that occurs during sign production benefits learning and whether it interacts with sign iconicity, which also enhances learning. American Sign Language (ASL) signs varying in iconicity were learned either via production (repetition) with the eyes closed or via observation without production. Signs learned via production were recalled more accurately than signs learned via observation, indicating that motor encoding from manual production enriches the representations of signs. Moreover, the effect of motor encoding interacted with iconicity, suggesting that motor encoding may particularly enhance the recall of signs low in iconicity. Together, these results reveal the importance of somatosensory feedback as a key mechanism underlying the beneficial effect of production on sign learning, demonstrating that feeling one’s own signing promotes learning and recall of signs.

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.
