Speech intelligibility and its relation to auditory temporal processing in Czech and Swiss German subjects with and without tinnitus.

PURPOSE: Previous studies have shown that levels for 50% speech intelligibility in quiet and in noise differ for different languages. Here, we aimed to find out whether these differences may relate to different auditory processing of temporal sound features in different languages, and to determine the influence of tinnitus on speech comprehension in different languages. METHODS: We measured speech intelligibility under various conditions (words in quiet, sentences in babble noise, interrupted sentences) along with tone detection thresholds in quiet [PTA] and in noise [PTAnoise], gap detection thresholds [GDT], and detection thresholds for frequency modulation [FMT], and compared them between Czech and Swiss subjects matched in mean age and PTA. RESULTS: The Swiss subjects exhibited higher speech reception thresholds in quiet, higher threshold speech-to-noise ratio, and shallower slope of performance-intensity function for the words in quiet. Importantly, the intelligibility of temporally gated speech was similar in the Czech and Swiss subjects. The PTAnoise, GDT, and FMT were similar in the two groups. The Czech subjects exhibited correlations of the speech tests with GDT and FMT, which was not the case in the Swiss group. Qualitatively, the results of comparisons between the Swiss and Czech populations were not influenced by presence of subjective tinnitus. CONCLUSION: The results support the notion of language-specific differences in speech comprehension which persists also in tinnitus subjects, and indicates different associations with the elementary measures of auditory temporal processing.

Medical research production in native languages: A descriptive analysis of PubMed database.

INTRODUCTION: Language barriers in medicine can hinder effective communication, comprehension, and patient care. While English has emerged as the dominant language in global medicine, the importance of native languages should not be overlooked. This article aims to examine the extent of publishing in native languages by analyzing the PubMed database literature to gain further insights into the usage of native languages in medicine and medical research. METHODS: In December 2023, a comprehensive examination of the PubMed literature was conducted for each of the 55 registered languages. We searched for records published in each language (e.g., German[lang]) by applying language filters. Ethnologue provided data on the number of worldwide native speakers for each language, facilitating a comparative analysis. RESULTS: By December 2023, PubMed contained over 36 million publications, with 86.5% of them published in English. German, French, and Russian came after English, with over 700 thousand publications each. Among the languages analyzed, fourteen had fewer than 50 publications, nineteen had fewer than 100, twenty-two had fewer than 500, and twenty-five had fewer than one thousand publications. European languages were well-represented with thousands of publications each, while widely spoken languages such as Hindi and Arabic had limited representation. CONCLUSION: The production of medical research in native languages reflects the attention given to native languages in medicine and medical education within each country. It is crucial to provide due attention to these language-related issues and explore strategies for including native languages in medicine to bridge the gaps in language and medicine.

Binding Out of Relative Clauses in Native and Non-native Sentence Comprehension.

Pronouns can sometimes covary with a non c-commanding quantifier phrase (QP). To obtain such 'telescoping' readings, a semantic representation must be computed in which the QP's semantic scope extends beyond its surface scope. Non-native speakers have been claimed to have more difficulty than native speakers deriving such non-isomorphic syntax-semantics mappings, but evidence from processing studies is scarce. We report the results from an eye-movement monitoring experiment and an offline questionnaire investigating whether native and non-native speakers of German can link personal pronouns to non c-commanding QPs inside relative clauses. Our results show that both participant groups were able to obtain telescoping readings offline, but only the native speakers showed evidence of forming telescoping dependencies during incremental parsing. During processing the non-native speakers focused on a discourse-prominent, non-quantified alternative antecedent instead. The observed group differences indicate that non-native comprehenders have more difficulty than native comprehenders computing scope-shifted representations in real time.

Introduction of two new programming tools in Bengali and measurement of their reception among high-school students in Purba Bardhaman, India with the prototypic inclusion of a vector-biology module.

We introduce two new software tools, Bongojontro and Bongojontro Baksobandi, aimed at reducing the barriers to programming for native speakers of Bengali, the fifth most spoken language in the world. The highlights of these software include programming in the native language of Bengali, simpler construction of programs which is friendly for beginners, and the possibility of creating and using modules which can be used to incorporate a level of abstraction that can be helpful for users of different technical skills and roles. We introduced the software to students of two semirural schools in Purba Bardhamman, West Bengal, India. The participants were a section of class XI students of age group 16-17 from both the schools. 40 students provided the full data in the succeeding survey, with 2 providing incomplete data. Among those who participated in the survey, it was found that the reception was overwhelmingly positive, with mean score greater than 6(out of 7) in 12 out of 15 survey questions. The scores were especially high on the usage of their native language on the software and its easy workflow. However, the mean "ease of learning" score was a bit low (4.45/7) compared to the other high ratings. The prototypic vector-biology module, which was a part of Bongojontro Baksobandi, also received very favorable reviews. Further work along these lines using the software and its modules seems to be a promising avenue for useful research and inclusive development in education and information technologies.

Native and non-native listeners show similar yet distinct oscillatory dynamics when using gestures to access speech in noise.

Listeners are often challenged by adverse listening conditions during language comprehension induced by external factors, such as noise, but also internal factors, such as being a non-native listener. Visible cues, such as semantic information conveyed by iconic gestures, can enhance language comprehension in such situations. Using magnetoencephalography (MEG) we investigated whether spatiotemporal oscillatory dynamics can predict a listener's benefit of iconic gestures during language comprehension in both internally (non-native versus native listeners) and externally (clear/degraded speech) induced adverse listening conditions. Proficient non-native speakers of Dutch were presented with videos in which an actress uttered a degraded or clear verb, accompanied by a gesture or not, and completed a cued-recall task after every video. The behavioral and oscillatory results obtained from non-native listeners were compared to an MEG study where we presented the same stimuli to native listeners (Drijvers et al., 2018a). Non-native listeners demonstrated a similar gestural enhancement effect as native listeners, but overall scored significantly slower on the cued-recall task. In both native and non-native listeners, an alpha/beta power suppression revealed engagement of the extended language network, motor and visual regions during gestural enhancement of degraded speech comprehension, suggesting similar core processes that support unification and lexical access processes. An individual's alpha/beta power modulation predicted the gestural benefit a listener experienced during degraded speech comprehension. Importantly, however, non-native listeners showed less engagement of the mouth area of the primary somatosensory cortex, left insula (beta), LIFG and ATL (alpha) than native listeners, which suggests that non-native listeners might be hindered in processing the degraded phonological cues and coupling them to the semantic information conveyed by the gesture. Native and non-native listeners thus demonstrated similar yet distinct spatiotemporal oscillatory dynamics when recruiting visual cues to disambiguate degraded speech.

Lexical learning in a new language leads to neural pattern similarity with word reading in native language.

Previous neuroimaging studies have suggested similar neural activations for word reading in native and second languages. However, such similarities were qualitatively determined (i.e., overlapping activation based on traditional univariate activation analysis). In this study, using representational similarity analysis and an artificial language training paradigm, we quantitatively computed cross-language neural pattern similarity to examine the modulatory effect of proficiency in the new language. Twenty-four native Chinese speakers were trained to learn 30 words in a logographic artificial language for 12 days and scanned while performing a semantic decision task after 4-day training and after 12-day training. Results showed that higher proficiency in the new language was associated with higher cross-language pattern similarity in select regions of the reading network.

Word scanning in native and non-native languages: insights into reading with declined accommodation.

This study investigated the effects of declined accommodation on reading performance in non-native and native languages. Eighteen native Japanese speakers participated: eight presbyopes and ten non-presbyopes. In the experiment, participants were asked to scan, or sequentially read six-word items presented in two-line texts, identify a non-word target as quickly as possible, and indicate its location. In addition to the participant type (presbyopes/non-presbyopes) and language of the reading material (Japanese/English), viewing distance (35 cm/70 cm) and contrast (18%/100%) were manipulated. The results showed that the presbyopes exhibited worse reading performance than the non-presbyopes at closer distances irrespective of the language. Notably, the inferiority of the presbyopes' reading performance was more pronounced when they read in a non-native language than in their native language. It should be noted that differences in reading performance between the presbyopes and non-presbyopes were subtle for high-contrast words at longer viewing distances, indicating that age- or cohort-related perceptual, motor, and cognitive differences were almost negligible, but accommodation mattered. These results suggest that the effect of accommodation decline is influenced by the language of the reading material.

The role of intergroup biases in children's endorsement of information about novel individuals.

A great body of evidence suggests that children are remarkably selective in accepting information from different sources. Yet, very few studies have focused on children's learning about the attributes of others. In three experiments, we examined how 6- and 7-year-olds' ingroup and outgroup biases about novel target individuals and their biases to follow ingroup informants interact in social learning contexts. Overall, children exhibited a positivity bias, accepting positive testimony about ingroup and outgroup targets, but this bias was significantly higher for ingroup targets. Furthermore, whereas children accepted the positive testimony about ingroup targets regardless of the informant's group membership, children selectively relied on ingroup informants when endorsing information about outgroup targets. These results suggest that children's existing biases interact with their acquisition of knowledge in complex ways and shape their social evaluations. These findings may have important implications for developing strategies to prevent negative biases against outgroup individuals among children.

Exploring sociodemographic subgroup differences in multiple mini-interview (MMI) performance based on MMI station type and the implications for the predictive fairness of the Hamburg MMI.

BACKGROUND: Sociodemographic subgroup differences in multiple mini-interview (MMI) performance have been extensively studied within the MMI research literature, but heterogeneous findings demand a closer look at how specific aspects of MMI design (such as station type) affect these differences. So far, it has not been investigated whether sociodemographic subgroup differences imply that an MMI is biased, particularly in terms of its predictive validity. METHODS: Between 2010 and 2017, the University Medical Centre Hamburg-Eppendorf (UKE) tested 1438 candidates in an MMI who also provided sociodemographic data and agreed to participate in this study. Out of these, 400 candidates were admitted and underwent a first objective structured clinical examination (OSCE) after one and a half years, including one station assessing communication skills. First, we analyzed the relationship between gender, age, native language and medical family background and MMI station performance including interaction terms with MMI station type (simulation, interview, and group) in a hierarchical linear model. Second, we tested whether the prediction of OSCE overall and communication station performance in particular differed depending on sociodemographic background by adding interaction terms between MMI performance and gender, age and medical family background in a linear regression model. RESULTS: Young female candidates performed better than young male candidates both at interview and simulation stations. The gender difference was smaller (simulation) or non-significant (interview) in older candidates. There were no gender or age effects in MMI group station performance. All effects were very small, with the overall model explaining only 0.6% of the variance. MMI performance was not related to OSCE overall performance but significantly predicted OSCE communication station performance with no differences in the prediction for sociodemographic subgroups. CONCLUSIONS: The Hamburg MMI is fair in its prediction of OSCE communication scores. Differences in MMI station performance for gender and age and their interaction with MMI station type can be related to the dimensions assessed at different station types and thus support the validity of the MMI. Rather than being threats to fairness, these differences could be useful for decisions relating to the design and use of an MMI.

Phonological selectivity in the acquisition of English clusters.

Phonological selectivity is a phenomenon where children preselect which target words they attempt to produce. The present study examines selectivity in the acquisition of complex onsets and codas in English, and specifically in the acquisition of biconsonantal (CC) clusters in each position compared to triconsonantal (CCC) clusters. The data come from the naturalistic productions of three English-speaking children. The results indicate that children only attempt to produce target tokens with a CCC onset after they have successfully produced target tokens with a CC onset, and that the same occurs in the case of codas. Frequency, morphological complexity, sonority, and /s/ clusters were examined and ruled out as possible explanations of these acquisition patterns. Overall, this suggests that children are selective in their target words, and only attempt to produce words that contain a cluster after they have produced words containing a shorter cluster of the same type (i.e., onset/coda).

Immigrants Psychopathology: Emerging Phenomena and Adaptation of Mental Health Care Setting by Native Language.

Mental health of immigrants is an important social and clinical issue. Immigrants may report higher rates of mental disorders and lower levels of use of mental health service with respect to natives. The aim of the present work is to review recent findings of the psychopathology of immigrants and analyze how to adapt the mental care settings through the use of mother tongues. We searched the literature to individuate and review the most recent scientific articles focused on the psychopathology of immigrants realized in Europe. Moreover, we summarized the guidelines about immigrants mental health care and we focused on the barriers caused by language. We individuated 15 papers reporting data about mental disorders among immigrants and the related risk and protective factors. The articles reported information about psychosis, depression, anxiety, post-traumatic stress disorder, somatization and suicide rates. Risk and protective factors are individuated mainly among social factors (e.g. ethnic density effect, hosting countries' policies). Furthermore, immigrants encounter language barriers in the use of mental care services. The realization of cross-cultural training and the development of a working alliance between clinicians and interpreters resulted to be effective solutions even if these interventions are not frequently implemented. The extent of migratory flows and the related difficulties experienced by immigrants require attention and well-informed interventions. The high rates of incidence of mental disorder and the strict number of services who implement interventions taking into accounts fundamental aspect as language show that there is still a lot to do.

[A tool for the language evaluation of bilingual children]. / Un outil pour l'évaluation langagière des enfants bilingues.

The native language is a vehicle for transmission and inscription into a culture. In children of migrants who grow up between two languages and two cultures, language develops in a context of bilingualism. This specific context requires bilingual assessments to ensure that a child's complete skills are assessed. The language assessment of non-French-speaking children and first-time immigrants, has been set up at Avicenne hospital in Bobigny. It is the first transcultural tool for the assessment of native languages.

The effect of non-native and non-regional speech testing on a multi-lingual population.

OBJECTIVE: This study was conducted to evaluate the speech perception of Malaysian Chinese adults using the Taiwanese Mandarin HINT (MHINT-T) and the Malay HINT (MyHINT). DESIGN: The MHINT-T and the MyHINT were presented in quiet and noise (front, right and left) conditions under headphones. Results for the two tests were compared with each other and with the norms for each test. STUDY SAMPLE: Malaysian Chinese native speakers of Mandarin (N = 58), 18-31 years of age with normal hearing. RESULTS: On average, subjects demonstrated poorer speech perception ability than the normative samples for these tests. Repeated measures ANOVA showed that speech reception thresholds (SRTs) were slightly poorer on the MHINT-T than on the MyHINT for all test conditions. However, normalized SRTs were poorer by 0.6 standard deviations for MyHINT as compared with MHINT-T. CONCLUSIONS: MyHINT and MHINT-T can be used as norm-referenced speech perception measures for Mandarin-speaking Chinese in Malaysia.

Repetition Priming Effects in Proficient Mandarin-Cantonese and Cantonese-Mandarin Bidialectals: An Event-Related Potential Study.

The present study adopted a repetition priming paradigm to investigate the bidialectal (bilingual) representation of speakers with different native dialects by event-related potential (ERP) technique. Proficient Mandarin-Cantonese and Cantonese-Mandarin bidialectals participated in the study. They were required to judge whether a word was a biological word or not, when the words (target word) were represented under four types of repetition priming conditions: Mandarin (prime)-Mandarin (target), Mandarin (prime)-Cantonese (target), Cantonese (prime)-Cantonese (target) and Cantonese (prime)-Mandarin (target). Results of reaction time and accuracy primarily indicated larger repetition priming effects in Mandarin-Mandarin and Cantonese-Cantonese (within-language) conditions than that in Mandarin-Cantonese and Cantonese-Mandarin (between-language) conditions. But more importantly, P200 and N400 mean amplitudes revealed distinct repetition priming effects between two types of participants. Specifically, both P200 and N400 indicated that the repetition priming effect in Mandarin-Mandarin condition was larger than that in Cantonese-Cantonese condition for Mandarin-Cantonese participants, whereas it was opposite for Cantonese-Mandarin participants. In addition, P200 also suggested opposite patterns of repetition priming effects in between-language priming conditions for two groups of participants. The repetition priming effect in Mandarin-Cantonese condition was larger than that in Cantonese-Mandarin condition for Mandarin-Cantonese participants, while for Cantonese-Mandarin participants, it was opposite (Mandarin-Cantonese < Cantonese-Mandarin). The results implied a clear asymmetric representation of two dialects for proficient bidialectals. They were further discussed in light of native dialect and language use frequency.

Medical education in a foreign language and history-taking in the native language in Lebanon - a nationwide survey.

BACKGROUND: With the adoption of the English language in medical education, a gap in clinical communication may develop in countries where the native language is different from the language of medical education. This study investigates the association between medical education in a foreign language and students' confidence in their history-taking skills in their native language. METHODS: This cross-sectional study consisted of a 17-question survey among medical students in clinical clerkships of Lebanese medical schools. The relationship between the language of medical education and confidence in conducting a medical history in Arabic (the native language) was evaluated (n = 457). RESULTS: The majority (88.5%) of students whose native language was Arabic were confident they could conduct a medical history in Arabic. Among participants enrolled in the first clinical year, high confidence in Arabic history-taking was independently associated with Arabic being the native language and with conducting medical history in Arabic either in the pre-clinical years or during extracurricular activities. Among students in their second clinical year, however, these factors were not associated with confidence levels. CONCLUSIONS: Despite having their medical education in a foreign language, the majority of students in Lebanese medical schools are confident in conducting a medical history in their native language.

Long-term experience with Chinese language shapes the fusiform asymmetry of English reading.

Previous studies have suggested differential engagement of the bilateral fusiform gyrus in the processing of Chinese and English. The present study tested the possibility that long-term experience with Chinese language affects the fusiform laterality of English reading by comparing three samples: Chinese speakers, English speakers with Chinese experience, and English speakers without Chinese experience. We found that, when reading words in their respective native language, Chinese and English speakers without Chinese experience differed in functional laterality of the posterior fusiform region (right laterality for Chinese speakers, but left laterality for English speakers). More importantly, compared with English speakers without Chinese experience, English speakers with Chinese experience showed more recruitment of the right posterior fusiform cortex for English words and pseudowords, which is similar to how Chinese speakers processed Chinese. These results suggest that long-term experience with Chinese shapes the fusiform laterality of English reading and have important implications for our understanding of the cross-language influences in terms of neural organization and of the functions of different fusiform subregions in reading.

Effects of sex and proficiency in second language processing as revealed by a large-scale fNIRS study of school-aged children.

Previous neuroimaging studies in adults have revealed that first and second languages (L1/L2) share similar neural substrates, and that proficiency is a major determinant of the neural organization of L2 in the lexical-semantic and syntactic domains. However, little is known about neural substrates of children in the phonological domain, or about sex differences. Here, we conducted a large-scale study (n = 484) of school-aged children using functional near-infrared spectroscopy and a word repetition task, which requires a great extent of phonological processing. We investigated cortical activation during word processing, emphasizing sex differences, to clarify similarities and differences between L1 and L2, and proficiency-related differences during early L2 learning. L1 and L2 shared similar neural substrates with decreased activation in L2 compared to L1 in the posterior superior/middle temporal and angular/supramarginal gyri for both sexes. Significant sex differences were found in cortical activation within language areas during high-frequency word but not during low-frequency word processing. During high-frequency word processing, widely distributed areas including the angular/supramarginal gyri were activated in boys, while more restricted areas, excluding the angular/supramarginal gyri were activated in girls. Significant sex differences were also found in L2 proficiency-related activation: activation significantly increased with proficiency in boys, whereas no proficiency-related differences were found in girls. Importantly, cortical sex differences emerged with proficiency. Based on previous research, the present results indicate that sex differences are acquired or enlarged during language development through different cognitive strategies between sexes, possibly reflecting their different memory functions.

Investigating the role of articulatory organs and perceptual assimilation of native and non-native fricative place contrasts.

The perceptual assimilation model (PAM; Best, C. T. [1995]. A direct realist view of cross-language speech perception. In W. Strange (Ed.), Speech perception and linguistic experience: Issues in cross-language research (pp. 171-204). Baltimore, MD: York Press.) accounts for developmental patterns of speech contrast discrimination by proposing that infants shift from untuned phonetic perception at 6 months to natively tuned perceptual assimilation at 11-12 months, but the model does not predict initial discrimination differences among contrasts. To address that issue, we evaluated the Articulatory Organ Hypothesis, which posits that consonants produced using different articulatory organs are initially easier to discriminate than those produced with the same articulatory organ. We tested English-learning 6- and 11-month-olds' discrimination of voiceless fricative place contrasts from Nuu-Chah-Nulth (non-native) and English (native), with one within-organ and one between-organ contrast from each language. Both native and non-native contrasts were discriminated across age, suggesting that articulatory-organ differences do not influence perception of speech contrasts by young infants. The results highlight the fact that a decline in discrimination for non-native contrasts does not always occur over age.

Non-native language comprehenders encode implied shapes of objects in memory.

Barsalou (1999) proposes that conceptual knowledge is represented by mental simulations containing perceptual information derived from actual experiences. Although a substantial number of studies have provided evidence consistent with this view in native language comprehension, it remains unclear whether the non-native language comprehension processes also include mental simulations. The current study successfully replicates the shape match effect in sentence-picture verification (Zwaan et al., 2002) for non-native English language comprehenders, indicating native-like visual simulations. In addition, participants displayed better delayed recognition memory when the shape of the depicted objects matched the shape that was implied by the sentence than when it did not, suggesting that visual simulations were generated spontaneously in naturalistic non-native language comprehension. Additional correlational analyses revealed no relationship between English proficiency and the size of the match effect.
