Inferential language use in the oral narratives of adolescents with and without developmental language disorder

ABSTRACT Inferential language is an essential aspect of narrative storytelling. It offers not only details about events such as cause and effect and character cognition (e.g. intentions, actions, and reactions) but other evaluative and descriptive language. Previous studies have shown that children with developmental language disorder (DLD, previously also termed as Specific Language Impairment, SLI) exhibit weakness in narrative development, and such weakness is suggested to be unlikely to be resolved over time. However, studies that have focused on the inferential language use in narratives of adolescents with DLD are almost non-existent, and it is unclear whether inferential language use by adolescents with DLD would remain problematic or achieve close-to-normal performance. To address this issue, we compared the use of inferential language in the oral narratives 19 adolescents with DLD (Mean age = 14.3; SD = 0.64) and 19 adolescents with typical language development (TLD; Mean age = 14.0; SD = 0.50). Each transcribed narrative was coded for inferences across character actions/attempts, internal states, causality, character dialogue and other inferences. Results indicated that the two groups performed similarly in all measures except for assigning possessive expressions. Our results suggest that adolescents with DLD may approximate their typical language development (TLD) peers in terms of the inferential language use in oral narratives.

Language, Motor Ability and Related Deficits in Children at Familial Risk of Schizophrenia or Bipolar Disorder.

It is known that impairments in linguistic ability and motor function tend to co-occur in children, and that children from families with parental mental illness such as schizophrenia tend to perform poorly in both domains, but the exact nature of these links has not yet been fully elucidated. In this study, we leveraged the first wave of the Danish High Risk and Resilience Study (VIA 7), which includes both genetic data and measures covering multiple developmental domains. The VIA 7 cohort comprises 522 7-year-old children born to parents with schizophrenia (N = 202), bipolar disorder (N = 120) or neither (N = 200). We investigated the relationships between linguistic ability and motor function using correlation and regression analyses, focusing on developmental coordination disorder (DCD) and specific language impairment (SLI) and their potential associations with the three risk groups. We found significant correlations between most measures of language and motor function and significant associations of DCD and SLI with language and movement measures, respectively, the largest effect being that of DCD on receptive language, with a significant interaction effect: DCD was associated with poorer performance in children from schizophrenia families compared to bipolar disorder and control families. Both disorders showed higher prevalence among children with familial high risk of mental illness. We did not find significant evidence of genetic overlap between DCD and SLI. Our results suggest strong links between the domains of motor function and linguistic ability. Children of parents with schizophrenia are at high risk of comorbid language and movement disorders.

Genome-Wide Mapping of Consanguineous Families Confirms Previously Implicated Gene Loci and Suggests New Loci in Specific Language Impairment (SLI).

Specific language impairment (SLI) is a developmental disorder with substantial genetic contributions. A genome-wide linkage analysis and homozygosity mapping were performed in five consanguineous families from Pakistan. The highest LOD scores of 2.49 at 12p11.22-q11.21 in family PKSLI-31 and 1.92 at 6p in family PKSLI-20 were observed. Homozygosity mapping showed a loss of heterozygosity on 1q25.3-q32.2 and 2q36.3-q37.3 in PKSLI-20. A loss of heterozygosity mapped, in PKSLI-31 and PKSLI-34 flanks, NFXL1 and CNTNAP2, which are genes previously identified in SLI. Our findings report novel SLI loci and corroborate previously reported SLI loci, indicating the utility of a family-based approach.

Development and Validation of the Tablet-Based ERAL Nonverbal Intelligence Test 5-17 (ERAL-NIT)

Intelligence has been extensively explored across various disciplines such as psychology, cognitive science, and neurology. Countless scholars have delved into understanding why certain individuals exhibit higher mental acuity and knowledge. Consequently, numerous studies aim to unveil the essence of intelligence and gauge human cognitive capacity. This study introduces and validates the ERAL Nonverbal Intelligence Test (ERAL-NIT) for children aged 5 to 17. Unlike many existing tests, ERAL-NIT is nonverbal, accommodating diverse linguistic backgrounds. Moreover, it incorporates parental assessments, enhancing its holistic approach. Administered via tablet with specialized software, ERAL-NIT provides comprehensive reports to practitioners and families. Its development integrates analyses of hemispheric specialization and executive functions of different brain areas. Content validity is ensured through expert input, while criterion validity is established by comparing results with established assessments and medical diagnoses. ERAL-NIT yields insights into pervasive developmental disorders, specific learning disabilities, attention deficits, and language disorders, thereby enriching diagnostic practices.

Psychometric Features of the Arabic Version of the Children's Communication Checklist (CCC2).

The Children's Communication Checklist-Second Edition (CCC-2) uniquely assesses overlooked communication elements such as pragmatics and context use, which are rarely addressed by conventional language assessments. This study focuses on the psychometric assessment of the CCC-2's Arabic version, tailored to evaluate communication challenges in Arabic-speaking children. This study aims to validate the Arabic version of CCC-2 by testing its reliability and validity specifically for three higher-order constructs: Specific Language Impairment (SLI), Social Communication Disorder (SCD), and Impaired Behaviour within the Arabic-speaking population. A total of 121 participants in Saudi Arabia, showcasing diverse age and gender distributions, participated in the validation process. The study employed a Reflective-Reflective Higher-Order Construct (R-R HOC) model using partial least squares-structural equation modeling (PLS-SEM) to ensure content validity and cross-cultural adaptation of the translated items. Metrics such as Cronbach's alpha for reliability and Average Variance Extracted (AVE) for convergent validity were specifically examined. The study confirmed the reliability and validity of the Arabic CCC-2, demonstrating robust psychometric properties, with Cronbach's alpha and AVE scores indicating satisfactory reliability and convergent validity across constructs. Structural model evaluation further supported the strong interrelations among the constructs of SLI, SCD, and Impaired Behaviour. The results substantiate the Arabic CCC-2 as a reliable and valid tool for assessing communication challenges in Arabic-speaking children, particularly for diagnosing SLI, SCD, and Impaired Behaviour. The validated Arabic CCC-2 has significant potential for application in clinical and educational settings and suggests directions for future research to explore its utility further in diverse clinical populations.

Quand penser à l’existence d’un trouble spécifique du développement et des apprentissages associé au TDAH de l’enfant ?

After the initial recommendations in 2014 on child attention deficit hyperactivity disorder (ADHD) published by the French Haute Autorité de santé (HAS), followed in 2018 by those devoted to specific learning and developmental disorders, and the new recommendations on child ADHD published in the third quarter of 2024 by the HAS, the issue of comorbidities between ADHD and other neurodevelopmental disorders remains a daily challenge for both families and professionals. This work therefore suggests that professionals who have suspected or diagnosed ADHD in a child or adolescent broaden their consideration, particularly concerning specific developmental and learning disorders that may be associated. They should rely on already available information, particularly from schools, and on screening tools accessible to primary and secondary care physicians before prescribing any additional assessments. Neurodevelopmental disorders include a large variety of conditions involving ADHD, motor disorders (among them developmental coordination disorder [DCD]), language and communication disorders (among them specific language disorder [SLD]), specific learning disorders (SLD) (written language both on the receptive and expressive side and mathematical disorders), autism spectrum disorders (ASD), and intellectual development disorder. We propose herein a brief description of these potential comorbid conditions, together with alert signs, which might give clues towards a diagnostic procedure of associated troubles. Moreover, comorbidities are often potential differential diagnosis. We therefore propose in our publication the tables published by the French HAS to help professionals to be aware of these conditions, with alert signs. Prevalence of these comorbidities benefit from our preliminary but exhaustive data from Parcours de Santé TSLA Occitanie on the prevalence of ADHD among complex neurodevelopmental disorders (NDD) with an estimation of more than 80% of concerned children and adolescent being eligible to a diagnosis of ADHD, representing an incidence of 5.6% between age 6 to 15. Among diagnosed ADHD children, comorbidities remain the rule, with specific learning disorders involving reading and spelling (dyslexia/dysorthographia): 46 to 62%, followed by developmental disorders: 41%, developmental language disorders: 24%, and specific learning disorders of mathematical abilities: 17%. This high-level of comorbidities confirms the need for each child to benefit from a multidisciplinary evaluation in various areas of development, particularly to detect secondary difficulties in learning (written language and math) or development (language, motricity), which might be masked by significant behavioural difficulties, or more subtly by pure inattention forms with primarily academic impact. Other comorbidities also need to be investigated, both towards social abilities, and secondary emotional consequences or comorbidities of ADHD including anxiety and depression. Our work also reviews data from literature about the conceptual framework between comorbidity and cause/consequence relationships, within a more comprehensive developmental perspective of various cognitive functions.

Intranasal Immunotherapy with M2 Macrophage Secretome Ameliorates Language Impairments and Autistic-like Behavior in Children.

Background/Objectives: The intranasal delivery of various neurotropic substances is considered a new attractive therapeutic approach for treating neuropathologies associated with neuroinflammation and altered regeneration. Specific language impairment (SLI) that arises as a result of damage to the cortical speech zones during the developmental period is one of the most common problems in preschool children, and it is characterized by persistent difficulties in the acquisition, understanding, and use of language. This study's objective is to evaluate the efficacy and safety of intranasal immunotherapy using the M2 macrophage secretome as a rich source of immunoregulatory and neurotrophic factors for the treatment of severe language impairment in children. Methods: Seventy-one children (54 boys and 17 girls, aged 3 to 13 years) were recruited to participate in a clinical trial (NCT04689282) in two medical centers. The children were examined before, 1 month after, and 6 months after the start of therapy. In the vast majority of children (55/71), language impairment was associated with autistic-like symptoms and attention deficit hyperactivity disorder (ADHD). Results: Daily intranasal inhalations of M2 macrophage-conditioned medium (for 30 days) were well tolerated and led to a decrease in the severity of language impairments, autistic-like behavior, and ADHD symptoms. The clinical effect appeared within a month after the first procedure and persisted or intensified during a 6-month follow-up. Two-thirds of the children showed a clear clinical improvement, while the rest had less pronounced improvement. Conclusions: Thus, the use of the M2 macrophage secretome and its intranasal delivery is safe, well tolerated, and clinically effective in children with severe language impairments.

A Preliminary Study on Characterizing Syntactic Processing and Pause Patterns in Bilingual English-Bahasa Indonesia Specific Language Impairment

A 12-year-old boy received a diagnosis of an unspecified "language disorder," suggesting the possibility of Specific Language Impairment (SLI) along with atypical pausing behavior. Interested to find out the possibility of incorporating pausing behavior into SLI diagnosis, this research sought to explore the distinctions in pause patterns between the spoken Bahasa Indonesia (BI) and English of Indonesian children, utilizing data from the child with suspected SLI (sSLI) and a control group for comparative analysis. Employing a quantitative approach and analyses related to phonology, syntax, and bilingual language production, the study revealed that the child with sSLI tended to display longer and more frequent pauses than the control group, particularly during communication in BI. Despite multiple influencing factors, pause patterns had the potential to serve as an indicative tool and a means to integrate bilingualism into the diagnosis of SLI.

Generative AI Applications in Helping Children with Speech Language Issues

This paper reports how generative AI can help children with specific language impairment (SLI) issues by developing an AI-assisted tool to support children with challenges in phonological development in English, especially children with English as the secondary language in the United States. Children from bilingual families often experience challenges in developing proficiency in English pronunciation and communication, which has been exacerbated by remote learning during the pandemic and led to learning loss. School-aged children with speech problems require timely intervention because children with language disorders find it difficult to communicate with others, leading to social isolation and academic difficulties. The needed intervention is often delayed due to the high cost of speech services and the shortage of Speech and Language Pathologists (SLPs). Individuals with a history of SLI have an increased risk of unemployment. An AI-assisted Phonological Development (AI-PD) tool was prototyped, aiming to alleviate these challenges by assisting caregivers in evaluating children's phonological development, assisting SLPs in lesson preparation, and mitigating the severe shortage of SLPs.

Assessment of Executive Functions in Children with Sensorineural Hearing Loss and in Children with Specific Language Impairment: Preliminary Reports.

Executive functions (EFs) are related abilities, associated with the frontal lobes functions, that allow individuals to modify behavioral patterns when they become unsatisfactory. The aim of this study was to assess EFs in children with sensorineural hearing loss (SNHL) and in children with "specific language impairment" (SLI), compared with a control group of children with normal development, to identify specific skill deficits. Three groups of preschool children aged between 2 and 6 years were assessed: 19 children with normal hearing, cognitive, and language development, 10 children with SNHL, and 20 children with SLI. The FE-PS 2-6 Battery was used for the assessment of preschool EFs, supplemented with the Modified Bell Test for the analysis of selective attention. Statistically significant differences were found between the two experimental groups and the control one, regarding the investigated skills. Children with SNHL showed a clear deficit in flexibility, whereas children with SLI had greater problems in self-regulation and management of waiting for gratification. Selective attention was found to be deficient in all three groups, with no statistically significant differences. This study shows that the skills investigated were found to be deficient in both SNHL and SLI patients. It is essential to start targeted exercises based on specific deficient skills as part of the rehabilitation program. It is of great importance to understand the consequences of EF deficit in preschool children to achieve an accurate diagnosis and carry out customized rehabilitation programs.

Beta Spectral Power during Passive Listening in Preschool Children with Specific Language Impairment

Introduction: Children with specific language impairment (SLI) have difficulties in different speech and language domains. Electrophysiological studies have documented that auditory processing in children with SLI is atypical and probably caused by delayed and abnormal auditory maturation. During the resting state, or different auditory tasks, children with SLI show low or high beta spectral power, which could be a clinical correlate for investigating brain rhythms. Methods: The aim of this study was to examine the electrophysiological cortical activity of the beta rhythm while listening to words and nonwords in children with SLI in comparison to typical development (TD) children. The participants were 50 children with SLI, aged 4 and 5 years, and 50 age matched TD children. The children were divided into two subgroups according to age: (1) children 4 years of age; (2) children 5 years of age. Results: The older group differed from the younger group in beta auditory processing, with increased values of beta spectral power in the right frontal, temporal, and parietal regions. In addition, children with SLI have higher beta spectral power than TD children in the bilateral temporal regions. Conclusion: Complex beta auditory activation in TD and SLI children indicates the presence of early changes in functional brain connectivity.

FLP: Factor lattice pattern-based automated detection of Parkinson's disease and specific language impairment using recorded speech

BackgroundTimely detection of neurodevelopmental and neurological conditions is crucial for early intervention. Specific Language Impairment (SLI) in children and Parkinson's disease (PD) manifests in speech disturbances that may be exploited for diagnostic screening using recorded speech signals. We were motivated to develop an accurate yet computationally lightweight model for speech-based detection of SLI and PD, employing novel feature engineering techniques to mimic the adaptable dynamic weight assignment network capability of deep learning architectures. Materials and methodsIn this research, we have introduced an advanced feature engineering model incorporating a novel feature extraction function, the Factor Lattice Pattern (FLP), which is a quantum-inspired method and uses a superposition-like mechanism, making it dynamic in nature. The FLP encompasses eight distinct patterns, from which the most appropriate pattern was discerned based on the data structure. Through the implementation of the FLP, we automatically extracted signal-specific textural features. Additionally, we developed a new feature engineering model to assess the efficacy of the FLP. This model is self-organizing, producing nine potential results and subsequently choosing the optimal one. Our speech classification framework consists of (1) feature extraction using the proposed FLP and a statistical feature extractor; (2) feature selection employing iterative neighborhood component analysis and an intersection-based feature selector; (3) classification via support vector machine and k-nearest neighbors; and (4) outcome determination using combinational majority voting to select the most favorable results. ResultsTo validate the classification capabilities of our proposed feature engineering model, designed to automatically detect PD and SLI, we employed three speech datasets of PD and SLI patients. Our presented FLP-centric model achieved classification accuracy of more than 95% and 99.79% for all PD and SLI datasets, respectively. ConclusionsOur results indicate that the proposed model is an accurate alternative to deep learning models in classifying neurological conditions using speech signals.

Speech therapy screening project in the islands of Lampedusa, Linosa and Ustica

In the general population of 5-year-old children, those with Specific Language Disorders represent about 7%. The difficulties, which are more evident in the first years of life, often continue into school age, for this reason, it is of crucial importance to promptly intercept these health needs to guarantee the management and resolution of linguistic difficulties which, if not treated, will transition to the area of school learning. This work aims to identify children at risk concerning language development. The screening program involved all classes of nursery school and the first and second year of primary school, evaluating possible linguistic problems in the 6-8 age group. The speech therapy screening involved the administration of the Articulation Test. From the analysis of the data, it emerged that 12% of the participants, i.e. 21 children (11 children resident in the municipality of Lampedusa and Linosa, 10 children resident in the municipality of Ustica) were identified as at risk for language delay. For children identified at risk, an in-depth clinical-diagnostic investigation was requested. From this experience of prevention and awareness at an early age for language disorders, the importance of identifying risky situations early on is evident to support the correct evolution of verbal production and avoid that a late intervention could make the most serious situation. Nursery school represents a crucial place and moment for recognizing a possible difficulty. Unfortunately, attention to children's language is not yet optimal and is often directed only to those cases that show obvious signs of delay. This is why early identification of difficulties and timely management by the speech therapist is so important.

Studies on the association of genes with language disorders in the post-genomic era

Since genetic research entered the post-genomic era, the high heritability of language disorders has been confirmed. A variety of genetic-related diseases may cause various types of language disorders in children and/or adults. This article has summarized language disorders and their underlying mechanisms by searching the Web of Science database over the last decade, and combed the genetic researches for dyslexia, frontotemporal degeneration, specific language disorder, childhood speech apraxia and other single diseases that are strongly associated with the language disorders. It also provided a discussion over the co-occurrence of multiple diseases, with an aim to revealing the genetic association and/or pathogenetic mechanism in order to provide inspiration for the prevention, diagnosis, and treatment of language disorders.

Humor Use in Speech and Language Therapy in Romania

Humor, as part of our lives, is also extremely important in different professional settings. Speech and language therapy (SLT) sector is addressing both children and adults with specific language disorders or with non-specific language disorders, secondary to different syndromes or disabilities. In the SLT area, humor is a way through which therapy sessions can be easily introduced, it being an intrinsic modality of approaching children and adults. This article illustrates the data collected in the first Romanian study regarding humor use in the SLT sector, focusing on the way humor is perceived by specialists, but at the same time on the participants’ needs regarding the enriching of the SLT field with more materials both digitally born and/or printed. This study presents extended descriptive data that help us consider humor as a vital element during speech therapy sessions, independently of the professionals’ age, gender, experience and to create a collection of data regarding humor use in speech therapy for future therapeutic effective interventions. Thus, the most relevant collected data are as follows: of the 210 participants in this research just 12 (5.7%) responded that they do not use humor in their professional sector; 94.3% use humor in language disorder therapy activities; 39% use humor in every therapeutic session; more than 68% of participants use verbal humor during their sessions; 199 (94.8%) say that therapeutic materials with humorous content are mainly presented in traditional format (physical material resources); 129 responded they use humor (61.4%) in virtual format too - (digital resources); 68 % of the participants strongly agree/agree that a humor assessment tool is necessary for the effective use of humor in language disorder therapy.

Sensory processing profile among a sample of Egyptian children with different types of delayed language development: correlations of different variables

BackgroundResearch on sensory processing, particularly its association with language disorders, has been increasing in recent years, aiming to understand the correlation between language and sensory processing. This study aimed to determine sensory profiles among children aged 36 and 120 months with language disorders (autism spectrum disorders (ASD), attention deficit hyperactivity disorders (ADHD), specific language impairment (SLI), and intellectual disability (ID)) and correlate their language ages with their sensory profile responses.ResultsThe study involved 120 children with language disorders (ASD, ADHD, SLI, and ID), and 30 typically developing children. All children were subjected to assessment by the Sensory Profile and the Preschool Language Scale Fourth Edition (PLS-4) Arabic edition. Based on their sensory profile, children with language disorders are distinguished from typically developing peers. The former has a higher prevalence of sensory modulation disorders as well as atypical emotional and behavioral responses to sensory inputs compared to typically developing children. Children with ASD have the highest atypical sensory responses, followed by those with SLI, ADHD, and ID. A negative correlation was found between some sensory profile scores and receptive language scores. Expressive language was related to oral processing in some subtypes of language disorders.ConclusionsThe study indicates that detailed sensory processing assessment in children reveals different faces for different types of language disorders.

Effect of music therapy on language skills in children with specific language impairment: A systematic review

Background: Specific language impairment (SLI) delays language development without any neurological damage or disease. This impairment extends to nonlinguistic tasks, such as music perception skills. In recent years, speech-language pathologists (SLPs) and music therapists (MTs) have collaborated to develop and improve approaches for children with communication disorders (CDs), including global developmental delay (GDD), SLI, mild developmental delay (DD), and the risk of developing reading difficulties, by integrating music therapy (MT) and speech therapy (ST). MT could be considered as one of the alternative methods offered to children with SLI to enhance their language skills. Objectives: The purpose of this study was to investigate the effectiveness of MT interventions on language skills in children with SLI and to investigate the characteristics of other intervention features in these studies, such as interventionists, intervention, settings, session type, and music methods. Materials and methods: The study was a systematic review conducted within the framework of the Preferred Reporting Items for Systematic Reviews and MetaAnalyses (PRISMA). The quality of the research results was assessed using the critical appraisal tools provided by the Joanna Briggs Institute (JBI). Results: Two studies met the inclusion criteria and were included in this systematic review. The two main types of MT employed were song cues and creative music therapy based on the Nordoff-Robbins approach. Current evidence suggests that music therapy improves components of language, including phonology, syntax, morphology, and other aspects of speech development, such as understanding sentences and memory for sentences, in children with SLI. Conclusion: MT can be a valuable and effective intervention for children with SLI. The introduction of transdisciplinary programs that integrate MT and ST could be recommended. However, MT training courses are required for SLPs.

Assessing Psychological Implications in Children with Delayed Verbal Communication and Vocabulary Development: A Systematic Review

Background: Delayed verbal communication and vocabulary development can significantly impact children's emotional well-being, social interactions, and overall psychological development. This systematic review aims to synthesize existing research on the psychological effects associated with these delays, focusing on how they affect children's emotional health, social skills, and cognitive functioning. Methodology: This review systematically analyzed studies that investigated the psychological consequences of delayed verbal communication and vocabulary development in children. The studies included were diverse in design, including cross-sectional, longitudinal, and mixed-method approaches. Key measures across studies included assessments of depressive and anxiety symptoms, social-emotional functioning, language skills, and cognitive abilities. The analysis synthesized findings from a range of populations, including children with developmental language disorders (DLD), specific language impairment (SLI), and autistic spectrum disorders (ASD). Results: The review found that children with delayed verbal communication and vocabulary development are at increased risk for a variety of psychological issues. These include higher levels of anxiety and depression, difficulties in social interactions, and cognitive challenges. Specifically, children with DLD and SLI were more likely to experience emotional difficulties, such as depressive symptoms and anxiety, compared to their peers. Pragmatic language difficulties were found to be particularly associated with later psychotic experiences and depressive symptoms. Peer problems, bullying, and socioemotional challenges were prominent among youth with language impairments. Additionally, deficits in higher-order language skills and cognitive abilities were linked to greater emotional and social difficulties. Conclusion: The psychological impacts of delayed verbal communication and vocabulary development are profound, affecting children's emotional well-being, social interactions, and cognitive development. Interventions should address both language difficulties and associated emotional and social challenges.
