Challenges of Translating Idiomatic Expressions: A Cross-Linguistic Analysis at a University in Hanoi, Vietnam

This study investigates the challenges students face when translating idiomatic expressions between English and Vietnamese and explores how linguistic and cultural factors influence the translation process. Utilizing a combination of translation task analysis and focus group discussions, the research reveals that students frequently rely on literal translations, resulting in inaccurate or nonsensical outcomes due to their inability to grasp the figurative meanings of idioms. Cultural mismatches, particularly the absence of equivalent expressions in Vietnamese, further complicate translation efforts, leading to significant misunderstandings. Additionally, linguistic barriers, such as syntactic differences between English and Vietnamese, hinder students' ability to produce natural and accurate translations of idiomatic expressions. The findings emphasize the critical role of cultural knowledge and syntactic flexibility in effective idiomatic translation. To address these challenges, the study recommends that translation training programs place greater emphasis on idiomatic understanding and cross-cultural competence. This study contributes to the growing body of literature on idiomatic translation by highlighting the interplay of linguistic and cultural factors and suggesting strategies to enhance translation accuracy.

The Role of Kinesics in the Formation of Idiomatic Expressions in Russian and English

The article explores the influence of kinesic phenomena, such as gestures and body movements, on the development of idiomatic expressions in both languages. It examines how culturally specific gestures and physical actions are verbalized and incorporated into idiomatic phrases, reflecting the unique cultural perceptions and communicative practices of Russian and English speakers. By conducting a comparative linguistic analysis, the study identifies similarities and differences in the way kinesics is integrated into idiomatic expressions, highlighting the role of nonverbal communication in language formation and its impact on the semantic richness of idioms. The findings of this research underscore the importance of understanding the cultural and linguistic contexts in which idiomatic expressions are used, offering insights for translators, linguists, and intercultural communication specialists.

Analysis of Two Translation Applications : Why is DeepL Translate more accurate than Google Translate?

DeepL Translate and Google Translate are two leading machine translation tools. The focus of this research is to analyze the accuracy of translation results provided by DeepL Translation and Google Translation specifically in translating English to Indonesian. This research used a qualitative approach of document analysis and interviews. The advanced neural machine translation technology of DeepL, by utilizing extensive data, enables it to recognize language nuances and provide contextually accurate translations. In contrast, Google Translate, despite having grown to be supported by hundreds of languages, often struggles with complex sentences and idiomatic expressions. DeepL's accuracy and natural-sounding translations make it a top choice for professional and detailed translations. The study concludes that DeepL's focus on quality and accuracy, rather than the breadth of language support, makes it a more reliable translation tool.

GeoEntity-type constrained knowledge graph embedding for predicting natural-language spatial relations

Natural-language spatial relations between geographic entities (geoentities) reflect diverse perceptions influenced by factors like location, culture, and linguistic conventions. These relations play a crucial role in supporting geospatial tasks, such as question answering and cognitive reasoning. While prior studies focused on a limited set of human-selected spatial terms and geometric attributes, they often overlooked essential semantic attributes. To overcome this limitation, we developed a Spatial Relation-based Knowledge Graph Embedding framework, SR-KGE, with new KG fusion functions to predict spatial relation terms among distinct geoentities. This method not only considers graph structures and the diversity of natural language expressions in the embedding and learning process, but also incorporates geoentity types as a constraint to capture spatial and semantic relations more accurately. Our experiments on two knowledge graph datasets, one small-scale and one large-scale, have both shown its superior performance in spatial relation inference compared to popular KGE models, including TransE, RotatE, and HAKE. We hope our research will advance the classic study of natural language described spatial relations in a more automated and intelligent way.

Children with Auditory Brainstem Implants: Language Proficiency and Reading Comprehension Process

Introduction: Auditory performance and language proficiency in young children who utilize auditory brainstem implants (ABIs) throughout the first 3 years of life are difficult to predict. ABI users have challenges as a result of delays in language proficiency and the acquisition of reading comprehension, even if ABI technology offers auditory experiences that enhance spoken language development. The aim of this study was to evaluate about the impact of language proficiency on reading comprehension skills in children with ABI. Method: In this study, 20 children with ABI were evaluated for their reading comprehension abilities and language proficiency using an Informal Reading Inventory, Test of Early Language Development-Third Edition (TELD-3), Categories of Auditory Performance-II (CAP-II), and Speech Intelligibility Rating (SIR). Three distinct aspects of reading comprehension were assessed and analyzed to provide a composite score for reading comprehension abilities. TELD-3, which measures receptive and expressive language proficiency, was presented through spoken language. Results: Studies have shown that there was a relationship between language proficiency and reading comprehension in children with ABI. In the present study, it was determined that the total scores of reading comprehension skills of the children who had poor language proficiency and enrolled in the school for the deaf were also low. The children use short, basic sentences, often repeat words and phrases, and have a restricted vocabulary. In addition, the children had difficulty reading characters and detailed paragraphs and could not remember events in a logical order. Conclusion: Children with ABI may potentially have complicated reading comprehension abilities due to lack of access to all the speech formants needed to develop spoken language. In addition, variables affecting the reading levels of children with ABI include factors such as age at implantation, duration of implant use, presence of additional disability, communication model, and access to auditory rehabilitation. The reading comprehension skills of ABI users were evaluated in this study for the first time in the literature and may constitute a starting point for the examination of variables affecting reading comprehension in this area.

Arabic Vocabulary And Its Cultural Influences On The Colloquial Tamil Language: Special Reference To South Tamil Nadu India/ المفردات العربية وتأثيراتها الثقافية في اللغة التاميلية العامية : جنوب ولاية تاميل نادو في الهند أنموذجا

Language is vital for exchanging opinions and ideas, expressing feelings, and fulfilling daily needs. Arabic stands out among other languages due to its various advantages and features. Tamil Nadu, one of the states in India, is known as the historical frame of the Dravidian civilization, one of India's oldest. It is situated in the southernmost part of Asia. Tamil Nadu's residents speak Tamil, an ancient and expressive language celebrated for its rich literature and esteemed position among Indian languages. Tamil Nadu's global prominence stems from its historical oceanic and commercial connections. Centuries ago, the state actively traded with China, Babylonia, Rome, the Levant, the Turks, and, notably, the Arabs. These trade interactions facilitated vigorous import-export activities and improved cultural exchange and integration among diverse peoples. This study focuses on the influence of the Arabic language on Tamil, particularly in contemporary usage, where many Arabic words have been integrated into Tamil vocabulary. This research emphasizes the everyday use of Arabic terms, especially in fields such as law, exemplified by terms like amal, asal, bark, taraf, waterish, wakeel, and wayeetha, etc. It examines the linguistic and cultural similarities and shared usage of words between these two distinct languages. The methodology adopted is qualitative. The primary data was collected through personal interviews and original texts. Secondary data were obtained from related books, and scholarly works and data were analyzed. This study concluded that Arabic influence in colloquial Tamil, especially in southern Tamil Nadu, needs more extensive research. The persistent Arabic influence on Tamil civilization and cultural practices is frequently mistaken for indigenous Tamil elements in academic and administrative contexts. Arabic words used in Tamil have their roots and origins, emphasizing their originality in the Arabic language rather than being borrowed from Tamil.

Dynamics of Motor Skill Learning in American and Israeli Toddlers With Varied Language Proficiency.

The aim of the present study was twofold: to determine if deficits in motor skill proficiency and learning were present in 2-year-old children identified with early expressive language delay compared to peers without the delay, and to distinguish how motor skill proficiency and learning behaviors may manifest differently across culturally and linguistically diverse backgrounds. The study involved 54 children (24-36 months of age), 23 of whom were identified as having an expressive language delay. Furthermore, 16 participants were American and English-speaking and 38 were Israeli and Hebrew-speaking. After motor and language skill proficiency was assessed using a variety of measures, each child and participating parent were introduced to a nonsymmetrical-shaped insertion task so that motor learning skills could be observed. This block insertion task was observed for each child at three time points and included a transfer task (same task, new nonsymmetrical shape). Children with early expressive language delay were statistically significantly more likely to exhibit deficits in fine-motor proficiency than peers without language delay, regardless of country of origin or language spoken. Furthermore, participants with language delay demonstrated significantly higher error rates in transfer task completion compared with peers. Finally, participants in the U.S. sample indicated lower fine-motor skills and higher error rates than those in the Israeli sample. Differences in motor skill proficiency were universally associated with language delay status, indicating support for the notion that language acquisition deficits may extend beyond the linguistic system even in young children identified as late talkers.

Recurrent acute kidney injury is associated with delayed language development in infants with Congenital Heart Disease.

Neurodevelopmental delay is common in children who undergo surgery for Congenital Heart Disease (CHD) in infancy. Cardiac surgery associated acute kidney injury (CS-AKI) occurs frequently in the paediatric cardiac Intensive care unit (ICU). Cardiac surgery associated acute kidney injury (CS-AKI) is associated with worse neurodevelopmental scores and delay in cognitive, language, and motor domains in children with CHD. No known data exist regarding the association of CS-AKI and motor and language subscales. In this study, we explored the relationship between CS-AKI and receptive and expressive language, as well as gross and fine motor delay. This was a single centre retrospective observational cohort study. Children who underwent surgery for CHD and developed recurrent CS-AKI in the first year of life who had follow-up neurodevelopmental testing using the Bayley Scale of Infant Development Version III were included. Neurodevelopmental delay subscales assessed included: receptive and expressive language, fine and motor skills. The study cohort included 203 children. Recurrent CS-AKI was significantly associated with lower scores in receptive and expressive language, as well as fine and gross motor on unadjusted analyses. On adjusted analyses, recurrent CS-AKI was significantly associated with severe receptive language delay. The independent association of recurrent CS-AKI with severe language delay in children who undergo surgery for CHD in infancy is novel. Our findings may contribute to the understanding of language impairment in this population. Further studies are required to better understand this relationship and any potentially modifiable factors.

Grandparent support moderates the relation between socioeconomic status and children's cognitive development.

Grandparents support American families in many ways, but they have often been overlooked in research on typical families (e.g., parents raising children). We examined whether grandparents have a positive influence on children's development by buffering the relation between parents' socioeconomic status (SES) and children's cognitive development. Parents (N = 437) from 45 U.S. states reported on 1,047 grandparent relationships with their 3- to 5-year-old children (Mage = 4.18 years) and how helpful grandparents are regarding financial, instrumental, emotional, and informational support, which were summed together across all grandparent relationships. We found that SES (a composite of family income and parents' average education) was significantly related to preschoolers' cognitive development (a composite of receptive and expressive language, literacy, and numbers). However, this relation was weaker when grandparents provided a higher level of support. Most families received grandparent support of basic child needs (e.g., clothing) and educational resources that could contribute to children's cognitive development (e.g., books). Grandparents provided greater financial, instrumental, emotional, and informational support to parents when they were emotionally close to the grandchild and interacted frequently. However, only emotional support was related to the geographical distance to the grandchild. These results suggest that even in parent-led American families, grandparents play a supportive, buffering role against the potential negative effects of lower SES on children's cognitive development.

Evaluating a targeted selective speech, language, and communication intervention at scale – Protocol for the Happy Talk cluster randomised controlled trial.

Background In areas of social disadvantage up to 40–50% of children enter preschool with speech and language skills significantly poorer than would be expected for their age. The Happy Talk trial tests if a community embedded, targeted selective speech and language programme that simultaneously engages with parents and early childhood educators, (1) improves language outcomes in children aged between 2 years 10 months and 6 years and (2) is cost effective for the health care system. Method The Happy Talk trial is a large scale cluster randomised trial of a 12-week manualised intervention delivered in pre/school settings serving socially disadvantaged communities, in Ireland. Seventy-two clusters will receive the intervention (12 participants per cluster). Parents and pre/school staff engage in group training and coaching in the form of 12 1-hour sessions for parents and four staff workshops, over the course of the pre/school year. Training/coaching includes core interaction skills (modelling, expanding, balancing questions and comments), early literacy and phonological awareness. Blinded assessments pre- and immediately post-intervention and at 6 months follow up, will measure the primary outcomes of children’s receptive and expressive language and functional impact, and secondary outcomes of quality of life. Parental responsiveness and educator-child interactions will also be evaluated. Discussion This robust study evaluates a public health approach to the delivery of speech language and communication intervention in the ‘real world’ in the community, which focuses on prevention and equity of access. Pilot work indicates that the programme is feasible, acceptable to parents and staff, cost effective, and suitable for implementation at scale. The trial includes a process evaluation, a well-developed economic evaluation and the outcomes are directly relevant to children, families and educators. This work has the potential to improve the long-term outcomes and life chances of people living in social disadvantage. Trial registration clinicaltrials.gov NCT06460090 Trial Management There is a formal governance structure to oversee the conduct and running of the trial, consisting of a trial management group and a steering committee. More details on the composition, roles and responsibilities of each committee can be found in the supplemental material.

Are Late Talkers Just Late? Neighborhood Density and Word Frequency Properties of Late Talkers' Spoken Vocabularies.

Typically developing toddlers extract patterns from their input to add words to their spoken lexicons, yet some evidence suggests that late talkers leverage the statistical regularities of the ambient language differently than do peers. Using the extended statistical learning account, we sought to compare lexical-level statistical features of spoken vocabularies between late talkers and two typically developing comparison groups. MacArthur-Bates Communicative Developmental Inventories American English Words and Sentences (N = 1,636) were extracted from Wordbank, a database of CDIs. Inventories were divided into three groups: (a) a late talker group (n = 202); (b) a typically developing age-matched group (n = 1,238); and (c) a younger, typically developing group (n = 196) matched to the late talkers on expressive language. Neighborhood density and word frequency were calculated for each word produced by each participant and standardized to z scores. Mixed-effects models were used to evaluate group differences. The late talker and younger, language-matched groups' spoken vocabularies consist, on standardized average, of words from denser phonological neighborhoods and words higher in frequency of occurrence in parent-child speech, compared to older, typically developing toddlers. These findings provide support for the extended statistical learning account. Late talkers appear to generally be extracting and using similar patterns from their language input as do younger toddlers with similar levels of expressive vocabulary. This suggests that late talkers may be following a delayed, not deviant, trajectory of expressive language growth.

Synthesizing Formal Semantics from Executable Interpreters

Program verification and synthesis frameworks that allow one to customize the language in which one is interested typically require the user to provide a formally defined semantics for the language. Because writing a formal semantics can be a daunting and error-prone task, this requirement stands in the way of such frameworks being adopted by non-expert users. We present an algorithm that can automatically synthesize inductively defined syntax-directed semantics when given (i) a grammar describing the syntax of a language and (ii) an executable (closed-box) interpreter for computing the semantics of programs in the language of the grammar. Our algorithm synthesizes the semantics in the form of Constrained-Horn Clauses (CHCs), a natural, extensible, and formal logical framework for specifying inductively defined relations that has recently received widespread adoption in program verification and synthesis. The key innovation of our synthesis algorithm is a Counterexample-Guided Synthesis (CEGIS) approach that breaks the hard problem of synthesizing a set of constrained Horn clauses into small, tractable expression-synthesis problems that can be dispatched to existing SyGuS synthesizers. Our tool Synantic synthesized inductively-defined formal semantics from 14 interpreters for languages used in program-synthesis applications. When synthesizing formal semantics for one of our benchmarks, Synantic unveiled an inconsistency in the semantics computed by the interpreter for a language of regular expressions; fixing the inconsistency resulted in a more efficient semantics and, for some cases, in a 1.2x speedup for a synthesizer solving synthesis problems over such a language.

GAIA therapeutic farm: Prospective study on multidisciplinary care efficacy.

The therapeutic farm "GAIA" in Sidi Thabet is a non-profit organization created in 2009, situated in the North-Western suburbs of the capital Tunis/Tunisia. Its main aims are the day-care for and the socio-professional integration of children and young adults between age 6 and 30 with diverse types of disability through multiple activities, such as pet assisted therapy and horticulture. to assess the potential benefits of therapeutic on-farm management. We conducted a prospective study including 50 children and young adults aged 7 to 30 years with intellectual disabilities and/or autism spectrum disorders. Study participants were evaluated before inclusion and after 10 months of care using a self-established questionnaire collecting socio-demographic and clinical variables, an evaluation of competences, and the Child Behavior Checklist (CBCL). Mean sub scores (externalization/internalization) of CBCL decreased significantly (p<0.002). Competences were significantly improved in the following domains: understanding of verbal language, gross and fine motor skills, body hygiene, spatial and temporal orientation, preschool and school learning achievements and social integration. These positive initial results should encourage the further development of this initiative with support of the community.

Optimization method of cable structure demolition driven by digital twin evolution model

The large-span cable structure has the problems of complex component connection, cumbersome demolition process and difficult process coordination, which lead to high construction safety risk and low efficiency. Moreover, the optimization of the construction process scheme is difficult, and the convergence and visualization of the finite element analysis are insufficient, which hinders the construction efficiency. This study proposes a cable structure demolition optimization method driven by the digital twin (DT) evolution model. From the perspective of virtual-real mapping, the DT evolution process of cable structure demolition is clarified. The virtualization method of physical demolition process is formed by integrating visual modeling, simulation modeling and data modeling. Taking full account of the temporal and spatial evolution of the demolition process, a DT evolution model of the demolition process is established. Starting from the information flow, component flow, control flow and their relationship, the problems existing in the process of demolition execution are analyzed. Driven by the twin evolution process, a data mapping method for the demolition process is proposed. The safety risk is characterized by the mechanical properties (MPs) of the structure, and the expression language of the data association relationship is established. The particle swarm optimization back propagation neural network (PSO-BPNN) is improved, and an intelligent analysis method of MPs in the whole process of demolition is proposed. The best construction scheme is obtained by integrating the changes in MPs between the various demolition steps. The information of the demolition evolution process is divided into functional modules, and a DT platform is developed to efficiently guide the actual construction. Taking the demolition process of a cable truss experimental model as an example, the effectiveness of the proposed method is verified. The research results show that the DT evolution model can accurately map the actual demolition process. The deep learning method analyzes the mechanical properties of the structure and obtains the best construction scheme quickly and accurately. The development and application of the twin platform improves the degree of visualization and realizes the efficient guidance of the virtual model to the actual construction.

Postoperative reorganization of the supplementary motor area complex: A possible latent bihemispheric network

PurposeBrain plasticity after multistep surgery in low-grade glioma is highly variable; the neurosurgical approach must be individualised and functional imaging can be used for this purpose.In supplementary motor area complex (SMAC) tumors, the early and adequate functional recovery of patients raises the possibility of a latent bihemispheric or “mirror” cortico-subcortical network, which would develop depending on the needs of each patient. MethodsFunctional and DTI-MR data from 4 right-handed patients with left frontal low grade gliomas near the SMAC, who were operated at least in two occasions were collected. The time of the reintervention was variable (18 months- 8 years), related to the tumor growth. All patients were evaluated by a neuropsychologist and imaged before each surgery, in a 3 T MR, with a 24 multichanel head coilMotor and expressive language task-fMRI and DTI sequences were obtained to evidence the main cortico-subcortical components of the SMAC. Data were processed with Brainwave (GE Medical Systems) and with an Iplan Fiber Tracking tool (MEDTRONIC), respectively ResultsNone of our patients presented permanent neurological deficits after the first or second functional surgery. Three patients with partial or complete resection of the left middle and / or inferior frontal gyrus, and the left frontal aslant tract evidenced new right hemispherical cortical activity. This right shift were not observed in the patient without left middle gyrus resection, indeed with partial absent of the left frontal aslant tract. ConclusionSMAC is a latent cortico-subcortical bihemispheric network that allows it to reorganize itself in response to specific neurological deficits. We highlight the importance in the cortical reorganization of the left middle frontal gyrus in the SMAC, closely connected with the essential language areas of this region, but also we focused in the potential cortioco-subcortical changes to compensate the functionality of the FAT.

Subjective and functional outcome measures to evaluate performance of pediatric cochlear implant

BackgroundThe majority of research on the effects of cochlear implants has been on clinical evaluations of efficacy (hearing and speech skills and auditory thresholds). But it is unclear how much clinical efficacy metrics (speech, hearing, and language tests) actually demonstrate how beneficial cochlear implants (CI) are in everyday circumstances. In this study, we aim to assess the performance of a child’s current CI with both subjective and functional outcomes measures. Also, we aimed to assess factors affecting these outcomes after CI.MethodsThe study group included 45 cochlear-implanted children, and their chronological age ranges between 4 and 12 years. Children were divided according to their language age into three groups: group 1 (G1) includes15 children with a language age of less than 2 years, group 2 (G2) includes 15 children with a language age of 2 to less than 4 years, and group 3 (G3) includes 15 children with language age 4 to 6 years. Assessment was done in two sessions: one for phoniatric evaluation and another for audiological evaluation.ResultsCI enabled children to develop speech perception in a closed manner evidenced by the early speech perception (ESP) test with pattern perception being the easiest and monosyllabic words being the most difficult and the least to develop. Most children with CI were able to control their voice, to a lesser extent to use speech in meaningful use in social situations and to develop communication strategies in oral situations which were the least to develop, and this was evident by Meaningful Use of Speech Scale. Children with CI were able to acquire language, and their receptive language was better than expressive language, but their language age was below their chronological age.ConclusionThe cochlear implant is an effective rehabilitative tool for the treatment of prelingually deafened children, and this was evident by our results. A hierarchal approach of speech assessment according to the language age of the child and selection of age-appropriate speech perception test is very important to assess cochlear-implanted children Speech recognition had a high degree of variability. Early implantation age and increased duration of implant experience were the most important factors associated with good performance with CI, better speech perception, and better language outcomes.

Strategies and sacrifices of family caregiving in the Somali-American community: a qualitative study

BackgroundAmong the many pressing concerns of the Somali-American community, and other similar immigrant and refugee communities as they grow in the United States, is the provision of care for older adults and adults with disabilities. The implications of effective caregiving range from the facilitation of community building and place-making to the delivery and management of healthcare on a systemic level. However, little is currently known about Somali-American family caregivers, including their duties and responsibilities, primary concerns, and the impacts of surrounding influences on their ability to fulfill their role.MethodsSemi-structured interviews were conducted with 10 Somali-American family caregivers in Somali language. The resulting transcripts were translated into English by a professional interpreter and analyzed using an inductive thematic analysis approach. A key informant from the community was additionally consulted for insights regarding cultural nuances and interpretations of idiomatic expressions and concepts.ResultsThematic analysis of the reports revealed the principal themes of visitation, patient accompaniment, and self-sacrifice through acceptance and God-consciousness as pervasive and salient concerns across participants. Furthermore, the heightened stresses of the COVID-19 pandemic revealed just how severe the consequences can be when access to culturally habituated navigational tools and coping mechanisms are restricted.ConclusionsIn light of our findings, the growing concern for discrimination and sociocultural discord in the Somali-American community presents a particularly prescient threat to the well-being and sustainability of family caregivers. Their experiences must be understood and used to promote education and partnership between the healthcare system and the community in order to build trust and ensure a healthy future for this indispensable population.

Exploring vowel errors produced in nonword repetition in children with speech and language disorders.

Accurate nonword repetition (NWR) is contingent on many underlying skills, including encoding, memory and motor planning and programming. Though vowel errors are frequently associated with childhood apraxia of speech (CAS), several recent studies have found that children with developmental language disorder (DLD) produce high rates of vowel errors in NWR tasks. This retrospective analysis explored whether the overall frequency and types of vowel errors produced in NWR distinguish children with DLD, children with CAS, children with speech sound disorder (SSD) and children with typical development (TD). We present data for 24 children (six per DLD, CAS, SSD and TD groups), ranging in age from 50-92 months. Children with DLD, CAS and SSD showed similar articulation scores and children with DLD and children with CAS showed similar expressive language scores. Total vowel errors, total monophthong errors, monophthong substitutions, diphthongization errors, total diphthong errors, diphthong substitutions and diphthong reduction errors were calculated by syllable length and group. Repeated measures analyses of variance were used to examine group differences. Children with DLD and children with CAS produced a higher frequency of total vowel errors compared to children with TD. Children with DLD produced more total monophthong errors than children with TD. Children with DLD and children with CAS produced more total diphthong errors than children with TD. For children with DLD, these were characterised by diphthong substitutions. For children with CAS, these were characterised by diphthong substitutions and diphthong reduction errors. For all measures, error rates in children with SSD did not significantly differ from any of the other three groups. Preliminary evidence indicates that children with DLD and children with CAS both show high rates of vowel errors in NWR tasks and weaknesses in encoding and memory. For children with CAS, additional motor planning difficulties are associated with an increased likelihood to reduce diphthongs. Children with SSD show more mild processing difficulties than children with DLD and children with CAS, though they do not perform as well as TD peers. Future work should replicate and further specify the processing weaknesses that affect vowel accuracy in NWR tasks in a larger sample. What is already known on the subject Nonword repetition (NWR) tasks are often included in diagnostic batteries to identify children with developmental language disorder (DLD). Poor performance on these tasks have historically been attributed to phonological working memory deficits in children with DLD. However, repeating nonwords relies on a number of underlying processing skills and many of these skills are affected to varying degrees in children with speech and language disorders. An in-depth analysis of vowel errors has the potential to reveal the shared as well as specific underlying processing weaknesses in children with DLD, children with childhood apraxia of speech (CAS) and children with speech sound disorder (SSD). What this paper adds to existing knowledge We found that children with DLD and children with CAS show low vowel competence compared to children with typical development. A nuanced examination of vowel error types further revealed that children with DLD and children with CAS show weaknesses in encoding and memory. Motor planning and programming weaknesses were unique to CAS. Children with SSD show more mild processing deficits and their performance did not significantly differ from any of the other three groups. What are the clinical implications of this work? Examining the types of vowel errors produced by children with DLD, children with CAS and children with SSD in NWR allows us to further specify the underlying processing weaknesses that differentiate these three groups. This research informs theoretical accounts of language processing in children with different types of speech and language disorders and has the potential to improve the diagnostic utility of NWR tasks.

Investigating the relationship between cognitive impairment and brain white matter tracts using diffusion tensor imaging in patients with prolactinoma.

Cognitive impairment is known to occur in patients with prolactinoma, but the underlying mechanism is unclear. To evaluate cognitive function in patients with prolactinoma and to investigate the basis of possible cognitive impairment in brain white matter changes using diffusion tensor imaging (DTI). 37 consecutive patients with prolactinoma and 37 healthy controls of similar age, sex, and education were enrolled in the study. Hormone levels were determined in all participants, comprehensive neuropsychological testing was performed, and DTI was used to reconstruct and evaluate white matter tracts. In patients with prolactinoma, short- and long-term visual and verbal memory, attention, concentration, and executive and language functions were impaired compared to the healthy group. When comparing the DTI results, lower fractional anisotropy (FA) values were found in the patients' right uncinate fasciculus (R-UF), indicating neuronal damage. After applying the Bonferroni correction, the two groups had no significant difference in 42 tracts (p > 0.0012 for all). A positive correlation was found between poor FA scores on the R-UF and low scores on long-term memory, category and letter fluency tests. In addition, patients with hypoprolactinemia had the worst short-term memory scores, while normoprolactinemia had the best scores. Also, the poorer R-UF FA values were found in the patients with hypoprolactinemia and the highest in those with normoprolactinemia. This study is the first to investigate reasons for cognitive dysfunction in patients with prolactinoma by DTI. No significant structural changes were found in brain tracts of patients with prolactinoma. Still, there may be a link between potential damage in the R-UF and cognitive dysfunction, and further research is needed. In addition, the results showed that the development of hypoprolactinemia is associated with cognitive dysfunction and emphasized that overtreatment should be avoided.
