ABSTRACT

Limited studies have examined demographic differences in children's vocabulary in longitudinal samples, while there are questions regarding the duration, direction, and magnitude of these effects across development. In this longitudinal study, we included over 400 Dutch children. Caregivers filled out N-CDIs when children were 9-11 months (measuring word comprehension, word production, and gestures) and around 2-5 years of age (measuring word production). At 2-5 years, we also administered a receptive vocabulary task in the lab. We examined demographic effects on vocabulary size across infancy and toddlerhood. We found a disadvantage for males in infants' gestures and toddlers' vocabulary production. We found a negative effect of maternal education on infants' caregiver-reported vocabulary, but a positive effect on toddlers' lab-administered receptive vocabulary. Lastly, we found a negative effect of multilingualism - but only for the lab-administered task. Examining predictors in large, longitudinal samples ensures their robustness and generalisability across development.

ABSTRACT

Objective: Research demonstrates that college educated, English language dominant bilinguals underperform relative to English speaking monolinguals on tests of verbal ability. We investigated whether accepting responses in their two languages would reveal improved performance in bilinguals, and whether such improvement would be of sufficient magnitude to demonstrate the same performance level as monolinguals. Method: Participants were college students attending the same university. Spanish-English bilinguals were compared to English speaking monolinguals on the Bilingual Verbal Ability Tests (BVAT), which include Picture Vocabulary, Oral Vocabulary, and Verbal Analogies. Results: When given the opportunity to respond in Spanish to items failed in English, bilinguals obtained significantly higher scores on all three subtests, and their performance matched that of monolinguals on Oral Vocabulary and Verbal Analogies. Conclusion: An "either-language" scoring approach may enable optimal measurement of verbal abilities in bilinguals. We provide normative data for use in applying the either-language scoring approach on subtests of the BVAT. We discuss the findings in the context of clinical assessment.

ABSTRACT

Introduction: This research aims to investigate the impact of students' language assessment literacy (LAL) on their cognition. The study specifically examines how different levels of LAL influence two critical factors: test anxiety and motivation to learn a second language. Methods: To achieve the research objectives, a questionnaire was administered to a sample of 415 university students in China. The questionnaire utilized a five-point Likert scale to assess students' levels of LAL, test anxiety, and motivation to learn a second language. Descriptive data were examined to reveal students' proficiency in LAL, along with their levels of test anxiety and motivation. Multilevel regression analyses were performed using Mplus to investigate whether students' LAL proficiency can predict their levels of test anxiety and motivation. Results: The findings indicated that the participating students had a proficiency level of approximately 60% in the content of the LAL questionnaire. The analysis further revealed the relationships between specific dimensions of LAL and both test anxiety and second language motivation. The multilevel regression analysis suggested that theoretical knowledge about language and language learning, the understanding of the impact and social value of language assessments, and the uses of assessments to enhance learning, positively predicted students' extrinsic motivation. Furthermore, students' understanding of the uses of assessments to learn and their theoretical knowledge about language learning were identified as positive predictors of intrinsic motivation. Additionally, it was observed that students' LAL did not significantly predict test anxiety. Discussion: These findings emphasize the significance of enhancing students' LAL due to the identified relationships between LAL dimensions and motivation to learn a second language. The study suggests pedagogical implications for improving LAL, with a focus on specific dimensions that positively impact students' motivation. The absence of a significant relationship between LAL dimensions and test anxiety prompts further exploration and consideration of additional factors influencing students' anxiety in language assessments.

ABSTRACT

Language proficiency assessments are pivotal in educational and professional decision-making. With the integration of AI-driven technologies, these assessments can more frequently use item types, such as dictation tasks, producing response features with a mixture of discrete and continuous distributions. This study evaluates novel measurement models tailored to these unique response features. Specifically, we evaluated the performance of the zero-and-one-inflated extensions of the Beta, Simplex, and Samejima's Continuous item response models and incorporated collateral information into the estimation using latent regression. Our findings highlight that while all models provided highly correlated results regarding item and person parameters, the Beta item response model showcased superior out-of-sample predictive accuracy. However, a significant challenge was the absence of established benchmarks for evaluating model and item fit for these novel item response models. There is a need for further research to establish benchmarks for evaluating the fit of these innovative models to ensure their reliability and validity in real-world applications.

ABSTRACT

Precedents and objectives: Dr Donna Jackson-Maldonado, researcher and professor at the Centro de Estudios Lingüísticos y Literarios of the Universidad Autónoma de Querétaro in Mexico, left us on November 30, 2021. In this article, we review her main scientific contributions related to the three fundamental axes on which she worked: language acquisition, language disorders and language assessment. Methods and results: Dr Jackson-Maldonado's studies on language acquisition included groups of premature babies, late talkers, and typical development children in bilingual and diverse socioeconomic conditions. Moreover, she studied atypical language development in children with hearing loss, children with developmental language disorders and children with Down syndrome and other syndromes. Finally, regarding language assessment, it should be noted that she led the Mexican Spanish version of the Communicative Development Inventories (CDI) that was used as a model for later adaptations in other Romance languages. Discussion and conclusion: Dr Jackson-Maldonado's methodological approach combined rigour with a creative and innovative scientific spirit, yet she integrated theory and clinical practice from its very beginning. She left us an immense research and personal legacy that we want to honour in this paper.

ABSTRACT

AIM: Language difficulties in children can have enduring impacts on their academic and emotional well-being. Consequently, early identification and intervention are critical. This study aimed to investigate the impact of introducing Språkfyran, a language screening tool, on the identification and referral rates for speech and language assessment compared to the previous method. METHODS: An observational study was conducted in Gotland, Sweden, using the medical records of 3537 children (53% boys) who were 3-4 years of age. The study period lasted between 5 January 2016 and 29 April 2022, encompassing data collection both before and after the introduction of Språkfyran. RESULTS: Following the introduction of Språkfyran, 15% failed the screening, compared to 20% with the previous speech test. However, referrals for assessment increased significantly with Språkfyran, rising to 7% compared to 3% with the speech test. CONCLUSION: The proportion of children who failed the Språkfyran screening was consistent with findings from previous studies. Children who failed the screening were more likely to be referred for speech and language assessment after the introduction of Språkfyran. This indicates that Språkfyran is a clinically relevant tool that promotes children's language development through increased referral rates.

ABSTRACT

BACKGROUND: Children who underwent posterior fossa tumor removal may have spoken or written language impairments. The present systematic review synthesized the literature regarding the language outcomes in this population. Benefits of this work were the identification of shortcomings in the literature and a starting point toward formulating guidelines for postoperative language assessment. METHODS: A systematic literature search was conducted, identifying studies with patients who had posterior fossa surgery before 18 years of age. Included studies were narratively synthesized to understand language outcomes by language function (e.g., phonology, morphosyntax) at a group and individual level. Furthermore, the influence of several mediators (e.g., postoperative cerebellar mutism syndrome (pCMS), tumor type) was investigated. A critical evaluation of the language assessment tools was conducted. RESULTS: The narrative synthesis of 66 studies showed that a broad spectrum of language impairments has been described, characterized by a large interindividual heterogeneity. Patients younger at diagnosis, receiving treatment for a high-grade tumor and/or radiotherapy and diagnosed with pCMS seemed more prone to impairment. Several gaps in language assessment remain, such as a baseline preoperative assessment and the assessment of pragmatics and morphosyntax. Further, there were important methodological differences in existing studies which complicated our ability to accurately guide clinical practice. CONCLUSION: Children who had posterior fossa surgery seem to be at risk for postoperative language impairment. These results stress the need for language follow-up in posterior fossa tumor survivors.

ABSTRACT

This study reviews the crucial role of language in Autism Spectrum Disorder (ASD) diagnosis and assessment in Saudi Arabia. Using tailored search strings, 206 relevant documents were retrieved from the Web of Science and Scopus databases. An increasing trend in ASD research in Saudi Arabia was observed through temporal analysis. Keyword analysis identified key themes including "autism," "language," "assessment," "diagnosis," "Saudi Arabia," and "children." The focus of research has shifted over the years, from pure clinical and diagnostic aspects to a more comprehensive approach that includes language and cultural factors in ASD evaluation. The findings underscore the need for culturally and linguistically sensitive assessment tools, acknowledging the impact of bilingualism on language development, and the importance of language difficulties in diagnostic decision-making. The study highlights the necessity for further research, especially longitudinal studies examining the influence of language and cultural factors on ASD outcomes. The findings are significant for clinical practice, emphasizing the need for linguistically sensitive approaches in ASD diagnosis and assessment. This research serves as a guide for future studies by identifying the gaps in existing literature and areas of focus. The study identifies crucial gaps in existing literature, particularly the need for longitudinal studies examining the influence of language and cultural factors on ASD outcomes. The findings underscore the importance of culturally and linguistically sensitive approaches in ASD diagnosis and assessment, providing a novel insight for future research and clinical practice in Saudi Arabia.

ABSTRACT

Grammatical language development in individuals with autism (without intellectual/language impairment) is mostly qualitatively comparable to language development in typically developing children of the same age. The majority of tasks used to study grammatical development require explicit performance (use of verbal language). Here, we administered an implicit categorization task (by biological sex) to understand which markers children use to implicitly infer grammatical gender representation in Italian (a gendered language where grammatical gender can be inferred via a determiner and/or word ending). Participants were asked to categorize photos of animals, relying on the names that differed in regard to the grammatical markers involved (i.e., lexical semantic, phonological, syntactic or phonological + syntactic). Children with autism displayed the same patterns observed in typically developing children: the lexical-semantic marker was categorized more accurately, followed in decreasing order by the phonological-syntactic marker and the phonological marker. The syntactic marker was the most difficult to categorize for both groups. In addition, children with autism showed an advantage in grammatical gender representation when using formal/grammatical markers than when using lexical/semantic markers. Such an implicit assessment allows for the investigation of more nuanced linguistic representations other than those expressed by traditional assessments.

ABSTRACT

Background: The typology of word order in Hindi (Subject-Object-Verb, SOV) differs from that of English (Subject-Verb-Object, SVO). Bilinguals whose two languages have conflicting word order provide a unique opportunity to understand how word order affects language processing. Earlier behavioural and event-related brain potential (ERP) studies with Spanish-Basque bilinguals showed longer reading times and more errors in the comprehension of OSV sentences than SOV sentences in Basque language, indicating that non-canonical word orders (OSV) were difficult to process than canonical word order (SOV). Purpose: This study was designed to explore how the difference in word order in Hindi and English languages affects N400 parameters in proficient Hindi-English bilinguals, using semantic congruity paradigm. Methods: Twenty-five proficient Hindi-English bilingual subjects were asked to silently read the congruent and incongruent sentences presented in one word at a time in both the languages. ERPs were recorded from midline frontal, central and parietal sites. Results: The mean amplitude of the N400 effect at the parietal sites in Hindi-English proficient bilinguals was larger for English than for Hindi but there was no significant difference in the N400 latencies. Conclusion: Hindi-English bilingual subjects processed SOV and SVO sentences with equal ease as evidenced by the N400 latencies. Higher amplitude of the N400 effect with English sentences indicate that placing 'Object' as the final word makes sentences more predictable than verb as the final word. Understanding the word order difference might help to unravel the neurophysiological mechanisms of language comprehension and may offer some insights in terms of functional advantage of a particular word order in bilinguals.

ABSTRACT

Underlying deficits in inattention, hyperactivity, and/or impulsivity might contribute to suboptimal test-taking behaviours during language assessments that can lead to diagnostic errors. Considerations of potential medication effects on estimates of children's nonword repetition, sentence recall, tense-marking, and narrative abilities are warranted given long-standing enthusiasm for these indices to serve as clinical markers for developmental language disorder (DLD). A battery consisting of 1 nonverbal, 1 reading, and 6 verbal measures was administered twice to 26 children (6-9 years) with independently diagnosed combined-type attention-deficit/hyperactivity disorder (ADHD). All participants had been prescribed stimulant medications for the management of their ADHD symptoms and were assessed off- and on-medication, with order counter-balanced across participants. Half of the participants had concomitant DLD. Examiners were unaware of children's clinical status during assessments or when they were testing children who had received medication. Effect sizes were calculated for each measure. Significant score differences indicating a beneficial impact of stimulant medications on children's performances were observed on the recalling sentences subtest of the Clinical Evaluation of Language Fundamentals and the Picture Peabody Vocabulary Test. Adjustments may be needed when speech language pathologists use sentence recall or receptive vocabulary measures to make diagnostic decisions with children who have ADHD.

ABSTRACT

Mobile-Assisted Language Learning (MALL) applications have been increasingly used by learners and instructors after the government imposed social and educational restrictions in Saudi Arabia for almost two years due to the Covid-19 pandemic. This research investigates Saudi EFL university learners' use of MALL applications, specifically Social Media Platform (SMP) applications, in their preparation for achievement exams post the Covid-19 pandemic social and educational restrictions. A questionnaire consisting of questions, as well as a range of open-ended question was designed and administered to 125 English major female learners who were enrolled at King Faisal University (KFU) in two different educational modes viz., regular (66) and distance (59) participation. Seven SMP applications - WhatsApp, YouTube, Telegram, Twitter, Instagram, Snapchat and Facebook - were used in this study. Data were analyzed quantitatively using the MANOVA test in SPSS, and qualitatively. The results have shown that both Regular Learners (RLs) and Distance Learners (DLs) used SMPs to prepare for their exams. The data analysis revealed that there were significant differences between RLs and DLs in their frequency of use of SMPs in preparation for exams. WhatsApp was the most frequently used SMP by RLs, whereas Telegram was the most frequently used SMP by DLs. Facebook was the SMP least frequently used by both groups. There were also statistically significant differences in favor of RLs over DLs in the frequency of use of SMPs in preparation for exams due to the Covid-19 pandemic Most participants reported that SMPs have a positive effect on their academic achievements. During the pandemic this was the main reason for continuing to use SMPs. Other reasons that emerged from the qualitative analysis of the open-ended responses included educational, technical and cognition reinforcement. The study results suggested implications for learners, instructors and educational policy makers.

ABSTRACT

BACKGROUND: Language concordance can increase access to care for patients with language barriers and improve patient health outcomes. However, systematically assessing and tracking physician non-English language skills remains uncommon in most health systems. This is a missed opportunity for health systems to maximize language-concordant care. OBJECTIVE: To determine barriers and facilitators to participation in non-English language proficiency assessment among primary care physicians. DESIGN: Qualitative, semi-structured interviews. PARTICIPANTS: Eleven fully and partially bilingual primary care physicians from a large academic health system with a language certification program (using a clinician oral proficiency interview). APPROACH: Interviews aimed to identify barriers and facilitators to participation in non-English language assessment. Two researchers independently and iteratively coded transcripts using a thematic analysis approach with constant comparison to identify themes. KEY RESULTS: Most participants were women (N= 9; 82%). Participants reported proficiency in Cantonese, Mandarin, Russian, and Spanish. All fully bilingual participants (n=5) had passed the language assessment; of the partially bilingual participants (n=6), four did not test, one passed with marginal proficiency, and one did not pass. Three themes emerged as barriers to assessment participation: (1) beliefs about the negative consequences (emotional and material) of not passing the test, (2) time constraints and competing demands, and (3) challenging test format and structure. Four themes emerged as facilitators to increase assessment adoption: (1) messaging consistent with professional ethos, (2) organizational culture that incentivizes certification, (3) personal empowerment about language proficiency, and (4) individuals championing certification. CONCLUSIONS: To increase language assessment participation and thus ensure quality language-concordant care, health systems must address the identified barriers physicians experience and leverage potential facilitators. Findings can inform health system interventions to standardize the requirements and process, increase transparency, provide resources for preparation and remediation, utilize messaging focused on patient care quality and safety, and incentivize participation.

ABSTRACT

Introduction: Various parental report instruments are available for assessing children's language skills at the end of the second year. However, comparison studies on their usability are lacking, and it is also open to question what kind of information the instruments provide when used in a parallel manner. This longitudinal study investigated which of the available three parental report instruments, when used at 2;0 (year;month), provides the most representative information on language development at 3;6. In addition, since most of the parental report instruments available focus specifically on expressive language, the role of receptive language ability was also investigated when analyzing the explanatory value of parental report instruments. Methods: The participants were 68 typically developing children. At 2;0, language skills were measured using the following measures: the Infant-Toddler Checklist of the Communication and Symbolic Behavior Scales Developmental Profile (ITC), the Short Form and Long Form versions of the Finnish Communicative Development Inventories (FinCDI-SF, FinCDI-LF), and the Reynell Developmental Language Scales III (RDLS). The outcome measures were receptive/expressive/ general language ability at 3;6 measured using RDLS. Results: The results of parental report instruments were significantly and positively associated with language ability at 3;6. The correlation between the combined value of ITC and FinCDI-SF and later language ability was stronger than correlations for each measure separately. The regression models with the results of parental report instruments as predictors explained 18-22% (p < 0.00) of the variability in the total RDLS score. However, when receptive language ability at 2;0 was included in the models as a predictor, R2 increased considerably (46-48%, p < 0.00). Discussion: The results adduce the usability of parental report measures along with the importance of measuring receptive language skills at 2 years of age. In summary, this study provides important insights into the clinical evaluation of early language ability.

ABSTRACT

Introduction: The purpose of the present study was to investigate whether information from the Swedish version of the Communicative Development Inventories III (SCDI-III) is informative to the Speech and Language Pathologist (SLP) when examining children with suspected speech and language disorders at a SLP unit. Method: Parents to 50 children (25 girls, 25 boys, age 30-80 months) that had been referred to the local SLP unit completed the SCDI-III. Nine children came from multilingual families and 41 children came from monolingual, Swedish speaking homes. The children were diagnosed as having developmental speech disorders (12) or developmental language disorders (33). Five children were not diagnosed with any disorder. Results: The results showed that the referred children performed significantly lower on scales for word production, grammar, and metalinguistic awareness, compared to a subset from the norms with a similar age and gender composition. Most children fell below the 10th percentile on word production and grammatical constructions. The intercorrelation between the three scales were in general substantial. Comparisons of children's performance on the vocabulary and grammar scales of SCDI-III, and the medical records revealed 18 cases of discordance that would have motivated further examination. The parents rated sometimes their child's vocabulary and grammar skills as higher and sometime as lower to the medical records. Discussion: Limitations due to attrition and sample size were discussed. It was concluded that the SCDI-III can provide valuable information to the examination at the SLP clinic in addition to parent interviews, observations of children, and various tests, and that the potential for adapted versions would be particularly high for examinations of multilingual children.

ABSTRACT

The Language Use Inventory (LUI) is a parent-report measure of the pragmatic functions of young children's language, standardized and norm-referenced in English (Canada) for children aged 18-47 months. The unique focus of the LUI, along with its appeal to parents, reliability and validity, and usefulness in both research and clinical contexts has prompted research teams globally to translate and adapt it to other languages. In this review, we describe the original LUI's key features and report on processes used by seven different research teams to translate and adapt it to Arabic, French, Italian, Mandarin, Norwegian, Polish, and Portuguese. We also review data from the studies of the seven translated versions, which indicate that all the LUI versions were reliable and sensitive to developmental changes. The review demonstrates that the LUI, informed by a social-cognitive and functional approach to language development, captures growth in children's language use across a range of linguistic and cultural contexts, and as such, can serve as a valuable tool for clinical and research purposes.

ABSTRACT

Compared with traditional language testing, which heavily emphasizes psychometric reliability, communicative language testing (CLT), which uses authentic tasks to measure communicative abilities, has long been dominant in language assessment. Given its widely acknowledged advantages and widespread use, CLT has become less controversial in the language assessment field and thus is receiving decreased scholarly attention. However, real-world communication, in which CLT is grounded, evolves over time, suggesting the need to update our understanding of it. To address this need and facilitate the further development of CLT theories and practices, this paper offers an up-to-date review of CLT, including its various approaches, implementation challenges, and suggestions for future research.

ABSTRACT

OBJECTIVES: Automatic speech and language assessment methods (SLAMs) can help clinicians assess speech and language impairments associated with dementia in older adults. The basis of any automatic SLAMs is a machine learning (ML) classifier that is trained on participants' speech and language. However, language tasks, recording media, and modalities impact the performance of ML classifiers. Thus, this research has focused on evaluating the effects of the above-mentioned factors on the performance of ML classifiers that can be used for dementia assessment. METHODOLOGY: Our methodology includes the following steps: (1) Collecting speech and language datasets from patients and healthy controls; (2) Using feature engineering methods which include feature extraction methods to extract linguistic and acoustic features and feature selection methods to select most informative features; (3) Training different ML classifiers; and (4) Evaluating the performance of ML classifiers to investigate the impacts of language tasks, recording media, and modalities on dementia assessment. RESULTS: Our results show that (1) the ML classifiers trained with the picture description language task perform better than the classifiers trained with the story recall language task; (2) the data obtained from phone-based recordings improves the performance of ML classifiers compared to data obtained from web-based recordings; and (3) the ML classifiers trained with acoustic features perform better than the classifiers trained with linguistic features. CONCLUSION: This research demonstrates that we can improve the performance of automatic SLAMs as dementia assessment methods if we: (1) Use the picture description task to obtain participants' speech; (2) Collect participants' voices via phone-based recordings; and (3) Train ML classifiers using only acoustic features. Our proposed methodology will help future researchers to investigate the impacts of different factors on the performance of ML classifiers for assessing dementia.

ABSTRACT

BACKGROUND: A number of practice barriers (e.g., time constraints, patient comorbidities and competing demands) exist as regards the evidence-based assessment of adult language within the acute hospital setting. There is need for an evidence-based, diagnostically validated, adaptable, comprehensive and efficient aphasia assessment. The Brisbane Evidence Based Language Test (EBLT) was developed to meet this need for a clinically appropriate and diagnostically robust assessment measure. Since the release of the EBLT, there has been no detailed investigation into speech and language therapists' (SLT) use and perceptions of the assessment. To inform future research and improvements to the EBLT, a better understanding of current language assessment practices, use and thoughts on the EBLT are required. AIMS: To investigate SLTs' current language assessment practices; and to explore the current usage and future directions of the Brisbane EBLT. METHODS & PROCEDURES: A convergent parallel mixed-methods study design with an electronic survey was utilized. The survey consisted of 16 multiple-choice, multiple-answer and free-text questions that explored respondents' perceptions of current language assessment measures, ideal language assessment features, Brisbane EBLT use, positives and negatives, and future directions for the EBLT. The survey was developed on Qualtrics and disseminated via email, social media and professional networks. Snowball sampling was used. Study inclusion criteria required participants to be qualified SLTs with clinical experience working with patients with aphasia. Quantitative data were analysed via descriptive and correlative statistics, and qualitative data were analysed via content analysis. OUTCOMES & RESULTS: The survey was completed by 115 SLTs from Australia, New Zealand, the United States, the UK, Canada, France, Lebanon and Belgium. Many respondents identified that a range of assessments is required to meet SLT clinical needs in the assessment of aphasia. Key desirable assessment features reported were: comprehensive, efficient, evidence-based, responsive and flexible. The EBLT was the most frequently used standardized measure reported by respondents (used by 78.63%). The EBLT reportedly has many positive features; however, respondents indicated dislike of the form layout, scoring and responsiveness. The majority of respondents indicated that the development of additional EBLT tests (94.29%) and additional cut-off scores (95.15%) would benefit their clinical practice. CONCLUSIONS & IMPLICATIONS: The study findings indicate that SLT assessment of language is complex and multifaceted. While the EBLT is reportedly used widely by SLTs, respondents identified areas for further research which would optimize the test's usability within their practice, to ultimately improve patient outcomes. WHAT THIS PAPER ADDS: What is already known on the subject Previous studies have explored existing SLT adult language assessment practices within acute settings; however, the most recent comprehensive study was completed in 2010. In 2020, the development, diagnostic validation, intra- and interrater reliability of the Brisbane EBLT were published. As of yet there has not been an investigation into clinician use and perspectives of the assessment since its release. What this paper adds to existing knowledge This study provides contemporary data about international aphasia assessment practices, as well as descriptive and qualitative information on the current use of the Brisbane EBLT, and the positives, negatives, and future directions for the assessment measure. What are the potential or actual clinical implications of this work? The study suggests that no one language assessment currently satisfies all SLTs' assessment needs. It additionally implies that a large proportion of SLTs believe that it is best practice to use multiple language assessment measures and select these based on the patient's presentation and context. Further research is required to aid the development of additional EBLT test versions and cut-off scores to improve SLT adult language assessment practices.
