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.

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.

A common way of acquiring multiword expressions is through language input, such as during reading and listening. However, this type of learning is slow. Identifying approaches that optimize learning from input, therefore, is an important language-learning endeavor. In the present study, 85 learners of English as a foreign language read short texts with 42 figurative English phrasal verbs, repeated three times. In a counterbalanced design, we manipulated access to definitions (before text, after text, no definition) and typographic enhancement (with bolding, without bolding). The learning was measured by immediate and delayed gap-fill and meaning generation posttests. All posttests showed that learning with definitions was better than without, and that access to definitions after reading was more beneficial than before reading. Typographic enhancement effectively promoted contextual learning of phrasal verbs and increased the learning advantage associated with presenting definitions after reading.

The current study examined the comprehension and production of classifiers, case marking, and morphological passive structures among 414 child Japanese heritage speakers (mean age = 10.01 years; range = 4.02 – 18.18). Focusing on individual differences, we extracted latent experiential factors via the Q-BEx questionnaire (De Cat, Kašćelan, Prévost, Serratrice, Tuller, Unsworth, & The Q.-Be Consortium, 2022), which were then used to predict knowledge and use of these grammatical structures. The findings reveal that: (i) experiential factors such as heritage language (HL) engagement at home and within the community modulate grammatical performance differentially from childhood through adolescence, and (ii) HL proficiency, immersion experiences, and literacy systematically predict HL grammatical outcomes. These results indicate that particular language background factors hold differential significance at distinct developmental stages and that higher proficiency, richer immersion experiences, and literacy engagement in the HL are crucial for the development of core grammatical structures.
