Vocabulary experts recommend first language (L1) translation equivalentsfor establishing form–meaning mappings for new second language (L2) words, espe-cially for lower proficiency learners. Empirical evidence to date speaks in favor of L1translation equivalents over L2 meaning definitions, but most studies have investigatedbi- rather than multilingual learners. In our study, we investigated instructed Englishvocabulary learning through an intervention study in six language-diverse secondaryschool English classrooms in Sweden (N=74) involving three conditions for presen-tation of word meanings: (a) definitions in the L2 (English), (b) translation equivalentsin the shared school and majority language (Swedish), and (c) translation equivalents inthe shared school and majority language plus other prior languages among the learners(Swedish and other). Based on overall weighted mean effect sizes and mixed-effects modeling, the results showed that conditions that involved L1 translation equivalentsyielded higher scores than did target language definitions in immediate posttests with asmall effect size but no differences in delayed posttests.

With the worldwide increase in people speaking more than one language, a better understanding of the behavioural and neural mechanisms governing lexical selection, lexical access in multiple languages and code switching has attracted widespread interest from several disciplines. Previous studies documented higher costs when processing a non-native (L2) than a native (L1) language or when switching from L2 to L1. However, studies on auditory language reception are still scarce and did not take into account the degree of switching experience. Accordingly, in the present study, we combined behavioural and electrophysiological measurements to assess lexical access in L1 and L2 as well as code switching in professional simultaneous interpreters, trainee interpreters, foreign language teachers and Anglistics students, while the participants performed a bilingual auditory lexical decision task. The purpose of this study was to expand the knowledge on code switching in auditory language processing and examine whether the degree of simultaneous interpretation experience might reduce switching costs. As a main result, we revealed that L2 compared to L1 trials, as well as switch compared to non-switch trials, generally resulted in lower accuracies, longer reaction times and increased N400 amplitudes in all groups of participants. Otherwise, we did not reveal any influence of switching direction and interpretation expertise on N400 parameters. Taken together, these results suggest that a late age of L2 acquisition leads to switching costs, irrespective of proficiency level. Furthermore, we provided first evidence that simultaneous interpretation training does not diminish switching costs, at least when focusing on lexical access.

To understand the vibrant and increasing interest in identity and second language acquisition (SLA), it is important to understand changing conceptions of the individual, language, and learning in the field. Each of these areas is associated with broader trends in the social sciences, which represent a shift in the field from a predominantly psycholinguistic approach to SLA to include a greater focus on sociological and anthropological dimensions of language learning, particularly with reference to sociocultural, poststructural, and critical theory (Norton & Toohey, 2001; Block, 2007b; Morgan, 2007). SLA researchers who are interested in identity are interested not only in linguistic input and output in SLA, but in the relationship between the language learner and the larger social world. They question the view that learners can be defined in binary terms as motivated or unmotivated, introverted or extroverted, without considering that such affective factors are frequently socially constructed, changing across time and space, and possibly coexisting in contradictory ways within a single individual. These researchers have examined the diverse social, historical, and cultural contexts in which language learning takes place, and how learners negotiate and sometimes resist the diverse positions those contexts offer them.

BACKGROUND An increasing number of children in the UK and Ireland are growing up speaking more than one language. The many advantages of bilingualism are acknowledged; however, this increased linguistic diversity presents particular challenges for speech and language therapists (SLTs). The case is often more complex with speakers of minority languages such as Welsh and Irish, which are acquired almost exclusively in bilingual contexts. Lack of appropriate standardized assessments for bilinguals is a key issue for SLTs internationally; however, little is known about the practices, personal perspectives or wider challenges faced by SLTs in assessing minority language skills. We focus on SLTs working with English-Irish bilinguals across Northern Ireland (NI) and the Republic of Ireland (ROI) where status, use and exposure to Irish differ significantly. AIMS To investigate the perceptions and practices of SLTs in NI and the ROI in the assessment of bilingual English-Irish-speaking children. METHODS & PROCEDURES A 33-item online survey was distributed to SLTs working with children in community settings in NI and the ROI. OUTCOMES & RESULTS A total of 181 SLTs completed the survey. The majority of respondents had bilingual English-Irish-speaking children on their caseloads; however, less than one-quarter had assessed Irish language skills. Responses indicate confusion as to whether best-practice guidelines applied in this particular context where the majority of speakers have English as their first language and limited domains of exposure to Irish outside of the education system. Resources available to assess Irish language skills were found to be limited. Informal analysis of language samples emerged as the most popular assessment tool. SLTs in the ROI had a significantly higher level of competence in the Irish language than SLTs in NI. This reduced the challenge of assessment. Many SLTs reported scoring assessments standardized on monolingual populations when assessing English language skills in bilingual English-Irish-speaking children. CONCLUSIONS & IMPLICATIONS Our findings highlight the challenges faced by SLTs in meeting best-practice guidelines in the assessment of speakers of minority languages such as Irish. Further work is needed to ensure clinicians and other professionals have access to information and enhanced training on bilingual language acquisition in minority language contexts and implications for assessment and diagnosis. This study underlines the need for further research on the acquisition of minority languages as well as the development of alternative assessment tools to assist SLTs in meeting the needs of this population. WHAT THIS PAPER ADDS What is already known on the subject Existing research indicates that SLTs face challenges in assessing bilingual clients. Lack of assessment resources is a global issue, particularly with respect to minority languages. Emerging research indicates that SLTs and other professionals are dissatisfied with current resources for assessing Irish-speaking bilinguals and are struggling to meet best-practice guidelines. What this paper adds to existing knowledge The status of the Irish language differs significantly between NI and the ROI, while English is the dominant language in both areas. This study provides the first exploration of current assessment practices for bilingual English-Irish-speaking children as reported by SLTs across both regions. The challenges of assessing bilingual clients in many other countries are mirrored by SLTs in NI and the ROI. The majority of children acquiring Irish are doing so in a specific context: the immersion education setting. This raises uncertainty for SLTs about whether the definition of bilingualism actually applies. Despite clinicians and clients sharing the same majority language, the complexity of minority language assessment remains. What are the potential or actual clinical implications of this work? SLTs require specific support and resources to help them meet the assessment needs of bilingual English-Irish-speaking children. Ongoing education and training are required for clinicians and other professionals to facilitate understanding of the complexities surrounding bilingual speakers of minority languages and the application of best-practice guidelines. A greater understanding of the context in which children are acquiring Irish and the impact this may have on their acquisition of English would further support clinicians in identifying speech, language and communication needs in this population.

BACKGROUND A growing body of work shows that children with developmental language disorder (DLD) perform poorly on statistical word learning (SWL) tasks, consistent with the predictions of the Procedural Deficit Hypothesis that predicts that procedural memory is impaired in DLD. To date, however, SWL performance has not been compared across linguistically heterogeneous populations of children with DLD. AIMS To compare SWL performance in a group of age, sex and non-verbal IQ-matched Catalan-Spanish and English-speaking children with and without DLD. METHODS & PROCEDURES Two cohorts of children: (1) 35 Catalan-Spanish-speaking children with DLD (Mage = 8;7 years) and 35 age/sex-matched typical developing (TD) children (Mage = 8;9 years), and (2) 24 English-speaking children with DLD (Mage = 9;1 years) and 19 age/sex matched TD controls (Mage = 8;9 years) completed the tone version of a SWL task from Evans et al. (2009). Children listened to a tone language in which transitional probabilities within tone words were higher than those between words. OUTCOMES & RESULTS For both Catalan-Spanish and English cohorts, overall performance for the children with DLD was poorer than that of the TD controls regardless of the child's native language. Item analysis revealed that children with DLD had difficulty tracking statistical information and using transitional probability to discover tone word boundaries within the input. For both the Catalan-Spanish and English-speaking children, SWL accounted for a significant amount of unique variance in Receptive and Expressive vocabulary. Likelihood ratio analysis revealed that for both Catalan-Spanish and English cohorts, children having performance ≤ 45% on the SWL task had an extremely high degree of likelihood of having DLD. The analysis also revealed that for the Catalan-Spanish and English-speaking children, scores of ≥ 75% and ≥ 70%, respectively, were highly likelihood to be children with normal language abilities. CONCLUSIONS & IMPLICATIONS The findings add to a pattern suggesting that SWL is a mechanism that children rely on to acquire vocabulary. The results also suggest that SWL deficits, in particular when combined with other measures, may be a reliable diagnostic indicator for children with DLD regardless of the child's native language, and whether or not the child is bilingual or monolingual. WHAT THIS PAPER ADDS What is already known on the subject Although there is some disagreement, a small but growing body of work suggests that deficits in procedural memory, as measured either by motor sequencing (Serial Reaction Time-SRT) or SWL tasks, may be part of the deficit profile of children with DLD. To date, studies have not examined SWL across linguistically heterogeneous populations of children with DLD to determine if it is a unique clinical marker of the disorder. What this paper adds to existing knowledge The results show that children with DLD, regardless of their native language, or whether the child is bi- or monolingual, have difficulties on SWL tasks, and that these deficits are linked to severity of the language disorder. Taken together, these results indicate that procedural memory deficits may be a core feature of DLD. This suggests that statistical-learning tasks using tone stimuli can also advance our understanding of statistical-learning abilities in children with DLD more globally. What are the potential or actual clinical implications of this work? The current study shows that statistical-learning tasks using tone stimuli can be used in conjunction with standardized assessment measures to differentiate children with DLD from children with typical language ability.

Refereed/Peer-reviewed The article presents a classroom-based study that engaged linguistically diverse preschool and early school-age children in illustrating books, jointly composing written narratives to accompany their illustrations, and enacting these child-authored books through shared sociodramatic play. Findings from story retell tasks show significant improvement in children's narrative language: vocabulary, syntax, accuracy, and text structure. Analysis of collaborative dialogue during book-making highlights the role of peer and teacher scaffolding in supporting children's literate language and identity development. The article presents an engaging play-based approach for ECE educators to (1) significantly and equitably increase child-led literate language interactions; (2) improve early writing instruction, by increasing meaningful composing experience; (3) strengthen culturally sustaining home/community–school partnerships, through authentic dialogue with caregivers about children's writing; and (4) harness the social and multimodal power of play to promote a range of important early learning goals.

The ability to differentiate between two languages sets the stage for bilingual learning. Infants can discriminate languages when hearing long passages, but language switches often occur on short time scales with few cues to language identity. As bilingual infants begin learning sequences of sounds and words, how do they detect the dynamics of two languages? In two studies using the head-turn preference procedure, we investigated whether infants (n = 44) can discriminate languages at the level of individual words. In Study 1, bilingual and monolingual 8- to 12-month-olds were tested on their detection of single-word language switching in lists of words (e.g., “dog… lait [fr. milk]”). In Study 2, they were tested on language switching within sentences (e.g., “Do you like the lait?”). We found that infants were unable to detect language switching in lists of words, but the results were inconclusive about infants’ ability to detect language switching within sentences. No differences were observed between bilinguals and monolinguals. Given that bilingual proficiency eventually requires detection of sound sequences across two languages, more research will be needed to conclusively understand when and how this skill emerges.

In recent years, there has been a rise in the number of people who are able to speak two or more languages. This has been paralleled by an increase in research related to bilingualism. Despite this, much of the neuroanatomical consequences and pathological implications of bilingualism are still subject to discussion. This review aims to evaluate the neuroanatomical structures related to language and to the acquisition of a second language as well as exploring how learning a second language can alter one's susceptibility to and the progression of certain cerebral pathologies. A literature search was conducted on the Medline, Embase, and Web of Science databases. A total of 137 articles regarding the neuroanatomical or pathological implications of bilingualism were included for review. Following analysis of the included papers, this review finds that bilingualism induces significant gray and white matter cerebral changes, particularly in the frontal lobes, anterior cingulate cortex, left inferior parietal lobule and subcortical areas, and that native language and acquired language largely recruit the same neuroanatomical structures with however, subtle functional and anatomical differences dependent on proficiency and age of language acquisition. There is adequate evidence to suggest that bilingualism offsets the symptoms and diagnosis of dementia, and that it is protective against both pathological and age-related cognitive decline. While many of the neuroanatomical changes are known, more remains to be elucidated and the relationship between bilingualism and other neurological pathologies remains unclear.

The past decade marked the beginning of the use of resting-state functional connectivity (RSFC) imaging in bilingualism studies. This paper intends to review the latest evidence of changes in RSFC in language and cognitive control networks in bilinguals during adulthood, aging, and early Alzheimer's disease, which can add to our understanding of brain functional reshaping in the context of second language (L2) acquisition. Because of high variability in bilingual experience, recent studies mostly focus on the role of the main aspects of bilingual experience (age of acquisition (AoA), language proficiency, and language usage) on intrinsic functional connectivity (FC). Existing evidence accounts for stronger FC in simultaneous rather than sequential bilinguals in language and control networks, and the modulation of the AoA impact by language proficiency and usage. Studies on older bilingual adults show stronger FC in language and frontoparietal networks and preserved FC in posterior brain regions, which can protect the brain against cognitive decline and neurodegenerative processes. Altered RSFC in language and control networks subsequent to L2 training programs also is associated with improved global cognition in older adults. This review ends with a brief discussion of potential confounding factors in bilingualism research and conclusions and suggestions for future research.

Previous work indicates mutual exclusivity in word learning in monolingual, but not bilingual toddlers. We asked whether this difference indicates distinct conceptual biases, or instead reflects best-guess heuristic use in the absence of context. We altered word-learning contexts by manipulating whether a familiar- or unfamiliar-race speaker introduced a novel word for an object with a known category label painted in a new color. Both monolingual and bilingual infants showed mutual exclusivity for a familiar-race speaker, and relaxed mutual exclusivity and treated the novel word as a category label for an unfamiliar-race speaker. Thus, monolingual and bilingual infants have access to similar word-learning heuristics, and both use nonlinguistic social context to guide their use of the most appropriate heuristic.

Background & aims Given that standardized language measures alone are inadequate for identifying functionally defined developmental language disorder (fDLD), this study investigated whether non-linguistic cognitive abilities (procedural learning, motor functions, executive attention, processing speed) can increase the prediction accuracy of fDLD in children in linguistically diverse settings. Methods & procedures We examined non-linguistic cognitive abilities in mono- and bilingual school-aged children (ages 8-12) with and without fDLD. Typically developing (TD) children (14 monolinguals, 12 bilinguals) and children with fDLD (28 monolinguals, 12 bilinguals) completed tasks measuring motor functions, procedural learning, executive attention and processing speed. Children were assigned as fDLD based on parental or professional concerns regarding children's daily language functioning. If no concerns were present, children were assigned as TD. Standardized English scores, non-verbal IQ scores and years of maternal education were also obtained. Likelihood ratios were used to examine how well each measure separated the fDLD versus TD groups. A binary logistic regression was used to test whether combined measures enhanced the prediction of identifying fDLD status. Outcomes & results A combination of linguistic and non-linguistic measures provided the best distinction between fDLD and TD for both mono- and bilingual groups. For monolingual children, the combined measures include English language scores, functional motor abilities and processing speed, whereas for bilinguals, the combined measures include English language scores and procedural learning. Conclusions & implications A combination of non-linguistic and linguistic measures significantly improved the distinction between fDLD and TD for both mono- and bilingual groups. This study supports the possibility of using non-linguistic cognitive measures to identify fDLD in linguistically diverse settings. What this paper adds What is already known on the subject Given that standardized English language measures may fail to identify functional language disorder, we examined whether supplementing English language measures with non-linguistic cognitive tasks could resolve the problem. Our study is based on the hypothesis that non-linguistic cognitive abilities contribute to language processing and learning. This is further supported by previous findings that children with language disorder exhibit non-linguistic cognitive deficits. What this paper adds to existing knowledge The results indicated that a combination of linguistic and non-linguistic cognitive abilities increased the prediction of functional language disorder in both mono- and bilingual children. What are the potential or actual clinical implications of this work? This study supports the possibility of using non-linguistic cognitive measures to identify the risk of language disorder in linguistically diverse settings.

BACKGROUND Intelligibility can be defined as the speakers' ability to convey a message to the listener and it is considered the key functional measure of speech. The Intelligibility in Context Scale (ICS) is a parent rating scale used to assess intelligibility in children. AIMS To describe normative and validation data on the ICS in Swedish and to investigate how these are related to age, gender and multilingualism. METHODS & PROCEDURES Two studies were included. Study 1 included ICS forms from 319 Swedish-speaking children (3:2-9:2 years:months). Study 2 included video recordings and ICS forms from 14 children with speech sound disorder (SSD) and two with typical speech. The video recordings were transcribed in the validation process, resulting in intelligibility reference scores to which ICS scores were correlated. OUTCOMES & RESULTS Study 1: The mean value of the ICS for the 319 children was 4.73. There were no differences in ICS score related to age or gender. The children in the multilingual group were significantly older than the monolingual group and had significantly lower ICS scores than the group of monolinguals. Study 2: There was a moderate correlation between the ICS score and the transcription-based intelligibility score, with the two children with typical speech excluded; however, this correlation was not significant. CONCLUSIONS & IMPLICATIONS We contribute mean scores and percentiles on the ICS for Swedish-speaking children. The finding that the ICS does not provide valid measures of intelligibility for the included children with SSD suggests that the instrument measures a different construct. WHAT THIS PAPER ADDS What is already known on the subject The ICS has been translated to numerous languages and validated against articulation measures in several previous studies. The validity of the Swedish version has been investigated against intelligibility based on transcription of single words. What this paper adds to existing knowledge The study provides normative values of the Swedish version of the ICS for children aged 3-9 years. This is the first study to use a gold standard measure of intelligibility in continuous speech to validate the ICS. The results show a somewhat dubious validity regarding ICS for the group of children with SSD included in the study. What are the potential or actual clinical implications of this work? The ICS's suitability as a measure of intelligibility is questionable; however, it might be of use for speech and language pathologists to give an overview of the parents' view of their child's ability to communicate, in order to make a decision on possible further assessment and intervention. The normative values of the Swedish version of the ICS could be of use in this decision process.

Linguistic ethnography provides insight into how communication occurs between individuals and institutions, while situating these local actions within wider social, political and historical contexts (Copland & Creese, 2015) and has proven to be a particularly effective tool for developing our understanding of individuals’ lived multilingual realities (see Unamuno, 2014) and societal multilingualism. Turning the ‘reflexive gaze’ that is central to ethnography (Clifford & Marcus, 1986) back onto linguistic ethnography itself, we argue that where complex multilingual interactions are the object of study, more attention must be given to how multilingualism affects each aspect of the process of actually doing linguistic ethnography. In this paper we outline the development of three principles that we put forward as being essential in developing and conducting contemporary linguistic ethnography in multilingual settings. The principles are: 1) Researching multilingually; 2) Researching collaboratively; and 3) Researching responsively.

This study explored how school administrators understand and plan for French immersion program components in K-12 schools in Louisiana. The theory of effective bilingual schooling and the Guiding Principles for Dual Language Education served as the framework of the study. The research questions that guided the study asked how school principals and assistant principals understand and plan for French immersion program components in K-12 schools. Purposive sampling was used to select five school administrators. Data were gathered through semi-structured, one-on-one interviews. The analysis of data used inductive thematic analysis. Five themes emerged: multilingualism and multiculturalism, academic achievement, leadership, teachers’ support, and program networking. Findings from this study were that school administrators developed a high degree of advocacy, teachers’ support, shared leadership, and strengthened communication and relationships with local, national, and international partners to deepen stakeholders’ involvement.

There is growing interest in the role of linguistic cues (accents, dialects, language) in driving children's social preferences. This meta-analysis integrated 131 effect sizes involving 2,680 infants and children from 2 days old to 11 years. Overall, children prefer native-accent, native-dialect, and native-language speakers over non-native counterparts (d = 0.57). Meta-regression highlighted that bilinguals (d = 0.93) do not exhibit less native-speaker preference compared to monolinguals (d = 0.62). Children displayed stronger preferences based on accent (d = 1.04) than dialect (d = 0.44) and language (d = 0.39). Children's cultural background, exposure to non-native speech, age, and preference measure were not significant moderators. The data are discussed in light of several theoretical explanations for when and why children show linguistic-based social preferences.

Multilingual learning and teaching have been receiving growing attention of late as many cities and states undergo significant demographic changes brought about by increasing levels of human migration. The onset of super‐diversity means that teachers often encounter students with very different language and cultural backgrounds in the classroom. This has created a new set of challenges and opportunities, especially concerning the teaching and learning of languages. As a result, research on language teaching and learning in super‐diverse contexts has acquired greater importance, yet the teaching of languages other than English (LOTE), specifically LOTE teacher beliefs and practices, has received comparatively little attention to date. To shed more light on teacher beliefs and practices as these concern the teaching of LOTEs to multilingual students, this study explored the extent to which 100 Arabic language teachers, working in UK‐curriculum secondary schools in the United Arab Emirates, used their students’ multilingualism as a resource during lessons and developed their self‐regulation and language awareness through specific activities. The findings regarding the participants’ efforts to develop their students’ self‐regulation and language awareness revealed an unexpected, negative correlation between their degree of multilingualism and their reported practices. publishedVersion
