Abstract
BACKGROUND Children with Developmental Language Disorder (DLD) and Reading Difficulties (RD) can show more peer relation problems depending on the informant. AIMS (1) To explore bullying victims' categorization, evaluated by self- and peer-reports, in children with DLD and RD; and (2) to assess agreement rates between informants. METHOD AND PROCEDURES Victimization was assessed using a self-report (EBIP-Q) and a peer-report sociogram (CESC) in a sample of 83 participants (9-12 years; 10.5 ± 1.1 years), comprising of DLD (n = 19), RD (n = 32), and Control (n = 32) groups. OUTCOMES AND RESULTS We found a higher frequency of the rejected sociometric profile in the DLD and RD groups, a higher peer-reported victimization in the DLD group, and more severe self-reported victimization in the DLD and RD groups. Odds of being classified as victimized were higher for self-report except in the DLD group. Informants' agreement was high using the most restrictive EBIP-Q criterion (7 points) for both the Control and the RD groups, being non-significant for the DLD group regardless of the criteria used. CONCLUSIONS AND IMPLICATIONS We found a higher victimization risk in children with language difficulties, although self-assessment seems to under-detect children with DLD according to the agreement rates, pointing out the need to combine assessments and informants. WHAT DOES THIS PAPER ADD?: Several studies have shown that children with DLD or RD obtain higher scores of victimization and score lower on several scales of social skills with continuous data. Although continuous analyses are usual in research, professional decisions are usually based on cut-off criteria more than how high or low a score is in contrast to another group. This is one of the first works that analyses victimization following the cut-off criteria of self and peer assessments that professionals used in the school settings in children with DLD and RD. Our results will raise awareness among school professionals based on the evidence about the high risk of victimization, especially in children with DLD, and the implications of selecting between several measures of victimization, in this group of children. We think that our results would help to better detect and prevent bullying in schools for children with DLD.

Abstract
Children with developmental language disorder (DLD) have a high rate of co-occurring reading difficulties. The current study aims to (i) examine which factors within the Active View of Reading (AVR; Duke & Cartwright, 2021) apply to individuals with DLD and (ii) investigate other possible factors that relate to reading comprehension ability in individuals with DLD, outside the components in the AVR. Electronic database search and journal hand-search yielded 5058 studies published before March 2022 related to reading comprehension in children with DLD. 4802 articles were excluded during abstract screening, yielding 256 studies eligible for full-text review. Following full-text review, 44 studies were included and further coded for demographics, language of assessment, description of reported disabilities, behavioral assessment, and reading comprehension assessment. While the results aligned with the AVR model, three additional factors were identified as significantly relating to reading comprehension abilities in children with DLD: expressive language (oral and written), question types of reading assessment, and language disorder history. Specifically, expressive language was positively associated with reading comprehension ability, while resolved DLD showed higher reading comprehension abilities than persistent DLD. Furthermore, children with DLD may face additional difficulties in comprehending inference-based questions. This study provides factors for researchers, educators, and clinical professionals to consider when evaluating the reading comprehension of individuals with DLD. Future research should further explore the relative importance of factors of the AVR to reading comprehension outcomes throughout development.

Abstract
PURPOSE Children with developmental language disorder (DLD) tend to interpret noncanonical sentences like passives using event probability (EP) information regardless of structure (e.g., by interpreting "The dog was chased by the squirrel" as "The dog chased the squirrel"). Verbs are a major source of EP information in adults and children with typical development (TD), who know that "chase" implies an unequal relationship among participants. Individuals with DLD have poor verb knowledge and verb-based sentence processing. Yet, they also appear to rely more on EP information than their peers. This paradox raises two questions: (a) How do children with DLD use verb-based EP information alongside other information in online passive sentence interpretation? (b) How does verb vocabulary knowledge support EP information use? METHOD We created novel EP biases by showing animations of agents with consistent action tendencies (e.g., clumsy vs. helpful actions). We then used eye tracking to examine how this EP information was used during online passive sentence processing. Participants were 4- to 5-year-old children with DLD (n = 20) and same-age peers with TD (n = 20). RESULTS In Experiment 1, children with DLD quickly integrated verb-based EP information with morphosyntax close to the verb but failed to do so with distant morphosyntax. In Experiment 2, the quality of children's sentence-specific verb vocabulary knowledge was positively associated with the use of EP information in both groups. CONCLUSION Depending on the morphosyntactic context, children with DLD and TD used EP information differently, but verb vocabulary knowledge aided its use.

Abstract
PURPOSE Previously, Lancaster and Camarata (2019) showed that the continuum/spectrum model of the developmental language disorder (DLD) best explained the high heterogeneity of symptoms in children with DLD. We hypothesize that the continuum/spectrum approach can include not only children with DLD but also typically developing (TD) children with different timelines and patterns of language acquisition. This model can explain individual language profiles and deficits in children. METHOD We assessed language abilities in a group of Russian-speaking children with DLD aged 4-7 years (n = 53) and their age- and gender-matched peers without speech and language diagnoses (n = 53, TD). We evaluated the children's performance at four language levels in production and comprehension domains, using 11 subtests of the standardized language assessment for Russian: Russian Child Language Assessment Battery (RuCLAB). Using the k-means cluster method and RuCLAB scores, we obtained two clusters of children and analyzed their language performance in individual subtests. RESULTS The analysis revealed that the two clusters of children both included DLD and TD participants: Group 1, with higher test scores (TD = 45, DLD = 24 children), and Group 2, with lower scores (TD = 8, DLD = 29). Children from Group 1 mostly had lower scores at one of the language levels, whereas those from Group 2 struggled at several language levels. Furthermore, children with DLD from both groups tended to be more sensitive to linguistic features such as word length, noun case, and sentence reversibility compared to TD children. CONCLUSIONS The presence of two mixed groups shows that children with diagnosed DLD could perform on par with TD children, whereas some younger TD children could perform similarly to children with DLD. Our findings support the continuum/spectrum model: Linguistic skills in preschool children are a continuum, varying from high to poor skills at all language levels in comprehension and production. To describe a child's language profile, the tasks assessing all language levels should be used. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.25521400.

Abstract
PURPOSE The word learning of preschool-age children with developmental language disorder (DLD) is improved when spaced retrieval practice is incorporated into the learning sessions. In this preregistered study, we compared two types of spacing-an expanding retrieval practice schedule and an equally spaced schedule-to determine if one of these approaches yields better word learning outcomes for the children. METHOD Fourteen children with DLD aged 4-5 years and 14 same-age children with typical language development (TD) learned eight novel nouns over two sessions. Spacing for half of the novel words was expanded gradually during learning; for the remaining novel words, greater spacing remained at the same level throughout learning. Immediately after the second session and 1 week later, the children's recall of the words was tested. RESULTS The children with TD recalled more novel words than the children with DLD, although this difference could be accounted for by differences in the children's standardized receptive vocabulary test scores. The two groups were similar in their ability to retain the words over 1 week. Initially, the shorter spacing in the expanding schedule resulted in greater retrieval success than the corresponding (longer spaced) retrieval trials in the equally spaced schedule. These early shorter spaced trials also seemed to benefit retrieval of the trials with greater spacing that immediately followed. However, as the learning period progressed, the accuracy levels for the two conditions converged and were likewise similar during final testing. CONCLUSION We need a greater understanding of how and when short spacing can be helpful to children's word learning, with the recognition that early gains might give a misleading picture of the benefits that short spacing can provide to longer term retention.

Abstract
BACKGROUND Disfluency is a multifactorial concept that can be linked to several of the language production levels, in both typical and atypical populations. In children, the language system is still developing and few studies have explored disfluency patterns. In typical development (TD), in particular, studies have shown discrepancies according to the language being considered. In neurodevelopmental disorders, such as developmental dyslexia (DD), it is still unclear whether the pattern of disfluency is similar to TD. AIMS To analyse the type of disfluency and their evolution in French children aged 8-12 years. Also to compare the pattern of disfluency in DD and TD, and to test whether disfluencies were correlated with reading difficulties. METHODS & PROCEDURES A total of 25 children with DD and 21 children with TD aged 8-12.6 years produced an autobiographical narrative. Seven types of disfluencies were coded: part-word repetitions; repetitions of monosyllabic words; other types of repetitions (words and phrases); filled pauses; revisions-substitutions; revisions-additions; and abandoned utterances. We compared the proportion of each disfluency in DD and TD. Spearman correlations were then performed between disfluencies, reading performance and age. OUTCOMES & RESULTS The results showed that both DD and TD children mainly produced filled pauses, repetitions of monosyllabic words and substitutions. Both groups displayed a high rate of disfluency (> 10%). No correlations with age were found. Correlations with reading performance were significant in the TD group only. CONCLUSIONS & IMPLICATIONS The study showed that DD is not characterized by a specific pattern of disfluency. Additionally, disfluency rates were similar in children aged 8-12 years. In contrast to other languages, the current study suggests that French-speaking children have a high rate of disfluency. The study also suggests that disfluency should be interpreted with caution in DD, given that TD children also have a high rate of disfluency. Therefore, it seems important to adapt the pathological threshold of disfluency to the language being spoken in order to avoid an overestimation of the prevalence of these deficits in French-speaking children. WHAT THIS PAPER ADDS What is already known on this subject TD children produce a high rate of disfluency, which is also influenced by the language being spoken. No study looked at the effect of DD on disfluency production. Nonetheless, problems in reading comprehension and reduced reading experience may impact lexical development and speech fluency. What this paper adds to the existing knowledge In our study, both groups (French-speaking children) produced a substantial amount of disfluency as compared with other languages (> 10%). Additionally, the pattern of disfluency was similar in TD and DD (namely, filled pauses, prolongations repetitions of monosyllabic words and substitutions). In the DD group, disfluency production was not correlated with reading performance. What are the potential or actual clinical implications of this work? These results indicate that it is crucial to consider the language being spoken when examining disfluency in order to avoid an overestimation of language difficulties in some languages, such as in French. Moreover, the production of disfluencies in DD should not be considered as language dysfunction since the pattern of disfluency what quite similar in TD and DD, and did not correlate with their reading difficulties.

Abstract
BACKGROUND Developmental language disorder (DLD) affects the ability to acquire and make use of native language. Possible underlying cognitive mechanisms are related to memory functions. AIMS The aim was examination of the relationship between visual short-term memory of objects as well as audiovisual short-term memory, and particular nonverbal and language abilities. METHODS AND PROCEDURES The study included 7-9-year-old children with DLD and matched control group. Participants completed the Language Development Test, the Stanford-Binet IQ scale (SB5), and two short-term memory tasks: immediate recall of the visually presented pictograms and immediate recall of audiovisually presented sequences of syllables. OUTCOMES AND RESULTS The results revealed diminished levels of short-term visual memory for objects as well as audiovisual memory in children with DLD. However, there were no group differences in the control task of WM. CONCLUSIONS AND IMPLICATIONS Results supported the idea of diminished abilities in children with DLD to perform mental operations on verbalizable visual objects. Importantly non-verbal working memory ability, which cannot easily be supported by verbal representations, is at typical levels. This suggests that verbalization ability should be taken into account in the assessment of seemingly non-verbal cognitive functions among children with DLD.

Abstract
Previous studies have reported that ASD children with more severe symptoms are diagnosed earlier. However, previous studies in community settings have mostly relied on retrospective parental reports without the use of quantitative standardized test scores. Here, we evaluated the association of language, cognitive, and ASD severity standardized scores with the age of diagnosis in 1-6-year-old children diagnosed in a public healthcare setting. The results revealed that language scores were the strongest variable associated with the age of diagnosis, explaining ~ 30% of the variability across children. Indeed, all children diagnosed before 30-months of age exhibited moderate-to-severe language delays. These results further substantiate the prominence of language delay as a highly visible symptom associated with earlier ASD diagnosis in community clinical settings.

Abstract
PURPOSE Children with developmental language disorder (DLD) show evidence of domain-general deficits in sequentially patterned motor skills. This study focuses on the production of rhythmically grouped sequences drawn from a music task, with the hypothesis that children with DLD will show a sequential pattern learning deficit that crosses language and action domains. METHOD Fifty-seven 4- to 5-year-old children (36 with DLD) drummed and clapped a developmentally appropriate musical rhythmic sequence 24 times (clapped 12 times, drummed 12 times). The accuracy of rhythmic events (markings of claps, drums, and pauses in a target sequence) was assessed through a modification of classic speech and language transcription procedures. The variability and prosodic structure of the rhythmic groupings were also measured. RESULTS Children with DLD produced less accurate and more variable rhythmic groupings compared to their typically developing (TD) peers. While the final-position grouping of the sequence was especially vulnerable for all children, those with DLD included more co-occurring errors in initial and final groupings of the same rhythmic sequence. Both TD children and children with DLD were less accurate in the clapping than the drumming task. Neither rhythmic drumming nor clapping accuracy correlated with motor skill in either group of children. CONCLUSIONS This study provides novel evidence of a manual rhythmic grouping deficit in DLD, one that is motivated by language-not motor or speech-factors. Cognitive abilities necessary to organize rhythmic events into higher order groupings are impaired across music and language in children with DLD. Rhythmic organization and sequencing may serve an important role in diagnosis and intervention in this population. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.24158745.

Abstract
Language is a complex multidimensional cognitive system that is connected to many neurocognitive capacities. The development of language is therefore strongly intertwined with the development of these capacities and their neurobiological substrates. Consequently, language problems, for example those of children with Developmental Language Disorder (DLD), are explained by a variety of etiological pathways and each of these pathways will be associated with specific risk factors. In this review, we attempt to link previously described factors that may interfere with language development to putative underlying neurobiological mechanisms of language development, hoping to uncover openings for future therapeutical approaches or interventions that can help children to optimally develop their language skills.

Abstract
Social cognition impairments may explain social, emotional and behavioural difficulties (SEBD) in individuals with Developmental Language Disorder (DLD). In a novel approach, the Social Attribution Task (SAT) was used to examine this association. SAT narratives were coded from 53 participants [n = 26 DLD; n = 27 typical language development (TLD)] matched on age (Mage = 13;6) and gender (35.9% female). Parents reported SEBD. Adolescents with DLD performed worse than their TLD peers on the majority of SAT indices and had higher peer (d = 1.09) and emotional problems (d = .75). There was no association between social cognition abilities and SEBD. These exploratory findings suggest social cognition should be further examined in this population.

Abstract
The current study examined how individual differences in language, nonverbal, and attention abilities relate to working memory in children with developmental language disorder (DLD) relative to age-matched typically developing (TD) peers using an interference-based model of working memory as our theoretical framework. Our experimental paradigm involved varying the domain (verbal/nonverbal) of recall items and an interference processing task, testing effects of interference. We examined the relative importance of language, nonverbal, and attention skills in predicting working memory performance by using Bayesian leave-one-out cross-validation to compare models with varied combinations of these skills as predictors. We then statistically tested selected models. Selected models were similar between groups for nonverbal, but not verbal, working memory. Language, nonverbal, and attention skills were associated with performance regardless of whether the working memory task was verbal or nonverbal for the DLD group, yet only attention was associated with verbal working memory for the TD group. A broader set of cognitive processes was involved in verbal recall in children with DLD than in TD peers, potentially reflecting diminished specialization of cognitive processes underlying language. The interference-based model of working memory accounted for interrelationships among language, processing speed, and inhibition of interference, revealing new insights into verbal processing.

Abstract
PURPOSE The purpose of this study was to determine the significance and directions of the relationships among oral and manual fine motor skills and language abilities among Spanish-English bilingual children. If such relationships exist, this would support a shared biological influence on motor and language development. METHOD Participants included 56 bilingual children, 24 of whom met criteria for developmental language disorder (DLD), recruited based on teacher concern for language and/or reading comprehension abilities. Students participated in a battery of baseline tests to determine motor, language, and cognitive abilities. Correlations among all variables were examined for direction of relationships. Regression models explored the predictive power of motor skills with Spanish and English language ability as the outcome measure. RESULTS Oral fine motor abilities (diadochokinetic rate productions of /pa/ and /pata/) predicted Spanish (but not English) oral language abilities in the expected direction (i.e., faster rates were associated with better language). Manual fine motor performance on computer tapping tasks was not related to performance in either language. CONCLUSIONS Oral fine motor abilities are related to language abilities in bilingual children, but only for the native language. We did not find reliable differences in oral and manual fine motor skills between groups of bilingual children with and without DLD. These findings support a limited role of shared biological influences on motor and language development.

Abstract
PURPOSE The aim of this study is to share the lived experiences of an adult with developmental language disorder (DLD) and relate her experience to the evidence base and issues in clinical practice. METHOD We co-wrote a first-person account grounded in the research literature. We organized the account into six main sections: (a) the early signs of DLD; (b) diagnosis; (c) treatment; (d) the impact of DLD on family relationships, social-emotional health, and academic performance; and (e) considerations for practicing speech-language pathologists. We close with (f) the first author's current perspective on life with DLD. CONCLUSIONS The first author was diagnosed with moderate-to-severe DLD in early childhood, and she continues to exhibit subtle and occasional symptoms of DLD as an adult. At specific points in development, her family relationships were disrupted and her social, emotional, and academic functions were disabled, particularly in the school context. Supportive adults, especially her mother and her speech-language pathologist, helped lessen these impacts. DLD and its consequences also positively influenced her worldview and professional choices. The precise nature of her DLD and her experiences around the disorder will not be true of everyone with DLD. Nevertheless, the broad themes that emerge from her narrative are reflected in the evidence base and thus are likely applicable to many individuals with DLD or other neurodevelopmental conditions.

Abstract
BACKGROUND It is well-documented that children with Developmental Language Disorder (DLD) have a higher likelihood of experiencing anxiety, as well as other socio-emotional and behavioural (SEB) difficulties. Despite this, there is little consensus as to how these difficulties manifest. This study aims to understand the prevalence of broader SEB difficulties and anxiety, informing intervention development by understanding the relationships between them. METHODS A mixed-methods, case-control study was conducted. First, an online survey was completed by 107 parents of either children with DLD ("DLD sample"; n = 57) or typically developing children ("typical sample"; n = 50), aged 6-12 years old. Binary SEB statements informed by previous qualitative work (e.g. "my child requires routine/sameness"; "my child has frequent tantrums") provided an insight into the prevalence of SEB difficulties in both DLD and typical samples. Validated measures of anxiety, emotion regulation, intolerance of uncertainty, insistence on sameness, family stress and coping mechanisms were also collected. Correlation and mediation analyses were run using these validated measures to understand the manifestation of anxiety in children with DLD in more detail. Qualitative interviews were then carried out with a select panel of survey respondents (n = 4). RESULTS The DLD sample scored significantly higher on all binary SEB statements than the typical sample: experiencing anxiety (80.7%, p < .05), requiring routine and sameness (75.4%, p < .001) and emotional dysregulation (75.4%; p < .001) were the most common difficulties reported for children with DLD. Using the validated scales, family stress and coping mechanisms were found to only correlate with the manifestation of anxiety in the typical group, not the DLD group. "Intolerance of uncertainty" and "insistence on sameness" were found to fully mediate the relationship between DLD diagnosis and symptoms of anxiety. Parent's interviews provided contextual support for the analysis, as well as highlighting sensory sensitivities as a focus for future research. CONCLUSIONS Parents of children with DLD appear to cope well with their children's complex SEB needs. Intervention focussing on intolerance of uncertainty may help the management of difficulties with anxiety. Behaviours such as insistence on sameness should be investigated further, as potential indicators for anxiety amongst children with DLD.

Abstract
PURPOSE Young people with developmental language disorder (DLD) have poorer mental health than those without DLD. However, not all young people with DLD are equally affected; some have more mental health difficulties than others. What explains these differences remains unclear. METHOD Data from a community cohort study, the Avon Longitudinal Study of Parents and Children, were analyzed to investigate genetic and environmental influences on the development of mental health difficulties at five time points from childhood (7 years) to adolescence (16 years) in 6,387 young people (8.7% with DLD). Regression and latent class models were fitted to the data. RESULTS Polygenic scores (PGSs), indices of genetic risk, for common psychiatric disorders (major depressive disorder, anxiety disorder, and attention deficit hyperactivity disorder) predicted mental health difficulties in both groups (with and without DLD). The presence of DLD, in some instances, amplified mental health difficulties for those with high genetic risk for common psychiatric disorders. Subgroups of children with similar developmental trajectories of mental health difficulties were identified. Young people with DLD were more likely than those without DLD to follow mental health subgroups characterized by consistently high levels of difficulties during development. PGSs, socioeconomic status, and the early home environment distinguished subgroups with low mental health difficulties from those characterized by high levels of difficulties, but these effects did not differ based on DLD status. CONCLUSIONS These findings suggest that, for the most part, both genetic and environmental risk affect the development of mental health difficulties in a cumulative way for young people with DLD (and those without). Some analysis did, however, suggest that genetic risk for common psychiatric disorders might manifest more strongly in those with DLD compared with those without DLD.

Abstract
PURPOSE This study examines online speech processing in typically developing and late-talking 2-year-old children, comparing both groups' word recognition, word prediction, and word learning. METHOD English-acquiring U.S. children, from the "When to Worry" study of language and social-emotional development, were identified as typical talkers (n = 67, M age = 27.0 months, SD = 1.4; Study 1) or late talkers (n = 30, M age = 27.0 months, SD = 2.0; Study 2). Children completed an eye-tracking task assessing their ability to recognize both nouns and verbs, to use verbs to predict an upcoming noun's referent, and to use verbs to infer the meaning of novel nouns. RESULTS Both typical and late talkers recognized nouns and verbs and used familiar verbs to predict the referents of upcoming nouns, whether the noun was familiar ("You can eat the apple") or novel ("You can eat the dax"). Late talkers were slower in using familiar nouns to orient to the target and were both slower and less accurate in using familiar verbs to identify the upcoming noun's referent. Notably, however, both groups learned and retained novel word meanings with similar success. CONCLUSIONS Late talkers demonstrated slower lexical processing, especially for verbs. Yet, their success in using familiar verbs to learn novel nouns suggests that, as a group, their slower processing did not impair word learning in this task. This sets the foundation for future work investigating whether these measures predict later language outcomes and can differentiate late talkers with transient delays from those with language disorders.

Abstract
BACKGROUND Early and effective treatment for children with developmental language disorder (DLD) is important. Although a growing body of research shows the effects of interventions at the group level, clinicians observe large individual differences in language growth, and differences in outcomes across language domains. A systematic understanding of how child characteristics contribute to changes in language skills is still lacking. AIMS To assess changes in the language domains: expressive morphosyntax; receptive and expressive vocabulary; and comprehension, in children in special needs education for DLD. To explore if differences in language gains between children are related to child characteristics: language profile; severity of the disorder; being raised mono- or multilingually; and cognitive ability. METHODS & PROCEDURES We extracted data from school records of 154 children (4-6 years old) in special needs education offering a language and communication-stimulating educational environment, including speech and language therapy. Changes in language were measured by comparing the scores on standardized language tests at the beginning and the end of a school year. Next, we related language change to language profile (receptive-expressive versus expressive-only disorders), severity (initial scores), growing up mono- and multilingually, and children's reported non-verbal IQ scores. OUTCOMES & RESULTS Overall, the children showed significant improvements in expressive morphosyntax, expressive vocabulary and language comprehension. Baseline scores and gains were lowest for expressive morphosyntax. Differences in language gains between children with receptive-expressive disorders and expressive-only disorders were not significant. There was more improvement in children with lower initial scores. There were no differences between mono- and multilingual children, except for expressive vocabulary. There was no evidence of a relation between non-verbal IQ scores and language growth. CONCLUSIONS & IMPLICATIONS Children with DLD in special needs education showed gains in language performance during one school year. There was, however, little change in morphosyntactic scores, which supports previous studies concluding that poor morphosyntax is a persistent characteristic of DLD. Our results indicate that it is important to include all children with DLD in intervention: children with receptive-expressive and expressive disorders; mono- and multilingual children, and children with high, average and low non-verbal IQ scores. We did not find negative relations between these child factors and changes in language skills. WHAT THIS PAPER ADDS What is already known on the subject Intervention studies indicate that intervention can be effective, but not for all children with DLD, and not in all language domains. Longitudinal studies on language development show stable growth patterns in children with DLD at the group level. A systematic understanding of how child characteristics contribute to changes in language skills is still lacking. What this paper adds to existing knowledge In this study, we report on the language gains of a cohort of 154 children with DLD (4-6 years old), in a special education setting for children with language disorders. Our sample includes children with receptive-expressive disorders and expressive-only disorders, and monolingual as well as multilingual children. Our results show that children's language skills improved. The co-normed tests we used revealed that the children had much lower growth in morphosyntax than in the other language domains. Language gains between children with receptive-expressive and expressive-only language disorders did not differ, children with lower initial test scores showed more improvement than children with higher initial scores, multilingual children showed more gains in expressive vocabulary than monolingual children, and there was no effect of non-verbal IQ on change in language scores. What are the potential or actual clinical implications of this work? The results suggest that catching up on language is possible for children with DLD. It is important to include all children with DLD in intervention: mono- and multilingual children; children with receptive-expressive and expressive disorders; and children with high, average and low non-verbal IQ scores. We did not find negative relations between these child factors and changes in language skills. The limited growth in morphosyntax compared with other linguistic areas warrants the attention of both practitioners and researchers, with a particular focus on the implementation of research findings in clinical practice.

Abstract
BACKGROUND Adolescents with Developmental Language Disorder (DLD) are at risk of emotional health problems and low self-esteem. However, little is known about their self-compassion (SC) and satisfaction with life (SWL). The present study compared self-compassion and satisfaction with life reported by Danish adolescents with DLD compared to typically developing (TD) peers, and whether severity of language difficulty is associated with SC and SWL. METHODS Results were obtained from 10 Danish adolescents with DLD compared with 14 age-matched TD adolescents and 132 TD peers, aged 15 years. RESULTS For SC and SWL results showed that adolescents with DLD reported more positive feelings compared to the TD adolescents. Interestingly for SC, the negative, but not the positive, domain differentiated the two groups, as adolescents with DLD reported less symptoms on self-judgment, isolation and overidentification. SC and SWL was strongly correlated with language abilities for the DLD group, but not for the TD group. CONCLUSIONS Results from our pilot study showed that Danish adolescents with DLD reported being less harsh on themselves. Language abilities were associated with self-compassion for the DLD, but not for the TD group. Whether these group differences are due to environmental factors such as the specific Danish school setting of the DLD group or internal factors are discussed and requires further research.

Abstract
BACKGROUND Adjectives are essential for communication, conceptual development and academic success. However, they are semantically and syntactically complex and can be particularly challenging for children with Developmental Language Disorder (DLD). Surprisingly, language interventions have not typically focused on this important word class. AIMS (1) To provide a supportive and accessible primer on adjectives for practitioners; (2) to explore how the SHAPE CODINGTM system can be adapted to support adjective learning in DLD; and (3) to provide practical recommendations on how to support adjective learning in clinical practice and education. METHODS/PROCEDURE We synthesise linguistic and psychological research on adjective semantics, clinical insights into DLD and pedagogical practice supporting this population. MAIN CONTRIBUTION We address the lack of specific training in the nature and acquisition of adjectives for speech and language therapists (SLTs) by providing an accessible primer. We also provide an innovative guide detailing how an established metalinguistic intervention might be adapted to support adjective learning. CONCLUSIONS/IMPLICATIONS Without targeted support for adjective learning, the communicative potential of children with DLD is compromised. Our recommendations can be used across a range of therapeutic and educational contexts to guide SLTs and teaching staff in developing practice in this area. WHAT THIS PAPER ADDS What is already known on the subject Adjectives are an essential word class needed for effective communication. They are also vital to successfully achieve academic objectives across all curriculum areas. For example, most subjects require children to be able to describe, evaluate, compare and discriminate different events, objects or techniques. Children with Developmental Language Disorder (DLD) have deficits in various domains of language that can affect adjective learning and use. What this paper adds to existing knowledge Despite the importance of adjectives, speech and language therapists (SLTs) and other professionals supporting language development rarely receive specific training regarding their structure and meanings, and how to teach and support their use. This article provides an accessible primer on the many subtypes of adjectives and how these behave syntactically and semantically. It explores how adjective teaching could be enhanced for children with DLD by adapting an established metalinguistic technique and provides practical recommendations for implementing this approach. What are the potential or actual clinical implications of this work? By raising awareness of the complexities of adjectives and providing strategies to support their acquisition by children with DLD, this article will enable SLTs and teaching staff to improve their understanding and practice in this area and, with further research, to develop robust, effective interventions for children with DLD. This will contribute to enhancing the long-term academic, social and employment success of children with DLD.

Abstract
BACKGROUND Variations in communicative participation of children with developmental language disorder (DLD) cannot be wholly explained by their language difficulties alone and may be influenced by contextual factors. Contextual factors may support or hinder communicative participation in children, which makes their identification clinically relevant. AIMS To investigate which contextual (environmental and personal) factors in early childhood are protective, risk or neutral factors for communicative participation among school-aged children with DLD, and to identify possible gaps in knowledge about this subject. METHODS & PROCEDURES A scoping review was conducted based on a systematic search of studies published from January 2007 to March 2022 in Pubmed, Embase (without MEDLINE), CINAHL and PsycINFO. In total, 8802 studies were reviewed using predefined eligibility criteria, of which 32 studies were included for data extraction and critically appraised using the Critical Appraisal Skills Programme (2021) tools. MAIN CONTRIBUTION The methodological quality of included studies was adequate to strong. Personal protective factors identified are being a preschool girl, reaching school age and being prosocial, while personal risk factors are becoming a teenager or adolescent, having low socio-cognitive skills and experiencing comorbid mobility impairment or behavioural problems. Gender after the preschool years and non-verbal abilities were not found to be of influence, and the role of socio-emotional skills is inconclusive. Receiving therapy is an environmental protective factor, while the association between socio-economical family characteristics with communicative participation is inconclusive. CONCLUSIONS & IMPLICATIONS Limited research has been conducted on which risk and protective factors present in early childhood are associated with later communicative participation of children with DLD. The influence of co-occurring health conditions, social background variables, individual psychological assets, interpersonal relationships and attitudes of other people represent knowledge gaps. In addition, knowledge about the comparative effectiveness of different types of interventions and service delivery models, and the impact of administrative control, organizational mechanisms and standards established by governments on children's communicative participation is lacking. More longitudinal research is needed focusing on the identification of relevant personal and environmental factors and the interactions between them in relation to communicative participation outcomes. WHAT THIS PAPER ADDS What is already known on this subject Children with DLD experience varying degrees of communicative participation restrictions. Insight into contextual factors that influence communicative participation can help to identify children at risk and inform family and child-centred therapy. Systematic research on contextual factors that facilitate or hinder communicative participation in children with DLD is currently lacking. What this paper adds to existing knowledge Knowledge of protective factors can guide the development of interventions for children and young people with DLD that boost resilience and facilitate communicative participation, while insight into the risk factors can help professionals identify the most vulnerable children and develop interventions that can lift or neutralize barriers present in the life of these children. Specific groups potentially at risk are young boys, children with co-morbid mobility impairment, children with conduct problems, and children reaching adolescence. In contrast, potentially protective factors are reaching school age and being prosocial. In addition, the development of socio-cognitive skills may be beneficial for the communicative participation of children with DLD. What are the potential or actual clinical implications of this work? To support communicative participation, it is important that professionals who work with children with DLD understand which groups are at risk for communicative participation restrictions, and which factors can foster resilience. In the absence of evidence-based instruments for the systematic assessment of personal and environmental factors, consulting parents and children on the contextual factors that they perceive as important remains critical.

Abstract
BACKGROUND Although there is a growing body of literature on cognitive and language processing in bilingual children with developmental language disorder (DLD), there is a major gap in the evidence for language intervention. Critically, speech-language therapists are often required to make clinical decisions for language intervention on specific domains, such as phonology, vocabulary, morphosyntax and literacy. AIMS To examine evidence for language intervention and cross-language transfer effects in bilingual children with DLD. Specifically, the study aimed to review intervention evidence targeting non-linguistic cognitive skills and six areas of language: phonology, vocabulary, morphosyntax, pragmatics, narrative skills and literacy. METHODS & PROCEDURES We carried out searches in five electronic databases: CINAHL, Scopus, Psychinfo, Proquest and Sciencedirect. Data from selected papers were extracted and organized into the three following categories: study information, participant information and intervention information. Critical appraisal for selected papers was conducted using a quality assessment tool (QAT). OUTCOMES & RESULTS We included 14 papers in the review. The majority indicated evidence for vocabulary intervention. There was limited evidence for intervention targeting phonology or morphosyntax. Cross-language generalization effects were evident for vocabulary, but in some instances also reported for morphosyntax and literacy. CONCLUSIONS & IMPLICATIONS The present review indicates that there is a significant gap in the literature regarding language intervention for several key language areas such as morphosyntax, narrative skills and literacy. There are only limited data for the effects of cross-language generalization indicating that more research is needed in this area specifically for skills beyond vocabulary. WHAT THIS PAPER ADDS What is already known on the subject Previous studies have examined the effects of bi- and monolingual intervention in bilingual children with DLD. Although the results indicated superior effects for bilingual compared with monolingual intervention, language intervention evidence in specific language domains (e.g., vocabulary, literacy) has not been investigated. What this paper adds to existing knowledge This study will add intervention evidence specific to language domains such as phonology, vocabulary, morphosyntax, pragmatics, narrative skills and literacy. Additionally, we have synthesized intervention evidence on non-linguistic cognition given that these skills are often impaired in bilingual children with DLD. The review has also demonstrated evidence for the effects of cross-language transfer beyond vocabulary skills, especially when the intervention was provided in the home language. What are the potential or actual clinical implications of this work? Although there was a lack of intervention evidence in language domains such as pragmatics, the results indicated some evidence for intervention targeting vocabulary. However, positive effects of cross-language generalization were not constrained to vocabulary but were also reported for intervention targeting mean length of utterance and literacy in the home language. This result indicates an interactive nature of the two languages, as well as provides further evidence for supporting home language(s) in intervention. Finally, intervention targeting non-linguistic cognition may yield additional cross-domain generalization to language skills specifically for bilingual children with DLD.

Abstract
BACKGROUND Some data call into question the persistence of developmental language disorders (DLDs) identified during the preschool period. For this reason, speech-language pathologists (SLPs) often reassess children. However, it is unclear if the instability of the profiles documented in community sample studies is present in children referred to specialized clinics. Given the scarcity of SLP resources, is re-evaluating the language skills of these children a good use of clinical time? AIM To examine the stability of the findings from two SLP assessments in a sample of Canadian preschool children referred to a tertiary clinic between the ages of 2 and 6 years. It was hypothesized that children under the age of 4 years at first assessment and children with less severe initial deficits would show less stability of DLD diagnosis. METHODS & PROCEDURES The clinical files of children referred to an early childhood psychiatric clinic in Canada were reviewed. For 149 children with two SLPs assessment reports, persistence of language deficits was documented and tested with McNemar's statistics. Differences between preschoolers under the age of 4 versus 4 years and over, as well as between mildly and severely impaired children, were examined. OUTCOMES & RESULTS High level of agreement (94%) and McNemar's test (p = 0.180) supported the stability of initial diagnosis. The stability for children assessed before the age of 4 (n = 64) was 100%, and was significantly different from older children's (n = 85) stability of 89% (Fisher's exact test, p = 0.01; bilateral). The stability for children with mild impairments (n = 18) was 78%, which was significantly lower than the stability (97%) in children with severe impairments (n = 114) (Fisher's exact test, p = 0.007; bilateral). CONCLUSIONS & IMPLICATIONS No instability of language status was observed in children assessed before 4 years of age, which could be related to the significant severity of the difficulties that children in this age group presented and be specific to this type of clinical sample. The great stability of language status observed in preschoolers referred to a specialized clinic suggests that clinicians should limit reassessments to devote available resources to intervention efforts. WHAT THIS PAPER ADDS What is already known on this subject? Previous research that has demonstrated important instability in the classification of language impairment before 4 years of age gathered data mainly by screening the general population or was not based on a comprehensive clinical assessment. What this paper adds to existing knowledge? This study investigated the classification stability of DLD between two comprehensive SLP assessments in a clinical sample of Canadian preschoolers. The results indicate great stability of language status assessed before 4 years old in this population, suggesting that severity of impairments may trump the age factor in this group. What are the potential or actual clinical implications of this work? In the case of children referred to a specialized clinic, clinicians and policymakers should be aware that DLD diagnosis made before 4 years of age remains stable during preschool age, and that a best practice with this population would be to abandon unnecessary testing in favour of early intervention.

Abstract
PURPOSE The current study compared the effects of direct instruction versus indirect exposure on multiple aspects of novel word learning for children with developmental language disorder (DLD) and children with typical language development (TLD). METHOD Participants included 36 children with DLD and 45 children with TLD. All children were in the first grade and 6-8 years of age (Mdn = 7 years; 2 months). Using a between-subjects design, children were randomly assigned to be exposed to novel words and their unfamiliar referents via either direct instruction (each referent presented in isolation with an explicit goal of learning) or indirect exposure (multiple referents presented with the goal of answering yes/no questions). RESULTS In alternative forced-choice measures of recognition, children with DLD were less accurate than their TLD peers in linking words to referents, encoding semantic categories for words, and encoding detailed representations of word forms. These differences in word learning were accounted for by a constellation of cognitive measures, including receptive vocabulary, phonological memory, visuospatial memory, and sustained attention. All children were similarly accurate in retaining word forms over a 24- to 48-hr delay. Children with TLD were more accurate in all aspects of word learning following direct instruction compared to indirect exposure. Benefits from direct instruction were observed for children with DLD in link and semantic, but not word form, learning. CONCLUSIONS These results suggest that vocabulary interventions with direct instruction can help children with DLD learn some, but not all, aspects of novel words. Additional support is necessary to help children with DLD encode rich phonological representations.

Abstract
BACKGROUND Previous research, although scarce, has indicated that the general public is still relatively unaware of developmental language disorder (DLD), one of the most common (neuro)developmental disorders. Raising awareness would increase timely involvement in intervention procedures. AIMS To examine public awareness of DLD in the neighbouring countries of Croatia, Italy and Slovenia, as well as to assess the influence of age, gender and education level on that awareness. Also, to investigate public knowledge about the professionals who recognize DLD and to compare the awareness of DLD with that of other (neuro)developmental disorders in childhood. METHODS & PROCEDURES A convenience sample of adults living in the countries of the Adriatic region-Croatia (N = 92), Italy (N = 105) and Slovenia (N = 90)-were asked to fill out a paper-and-pencil questionnaire (public survey) developed within the Working Group 3 of the COST Action IS1406. Responses were analysed quantitatively as a function of age, gender, education level and country using the t-test and analysis of variance (ANOVA). OUTCOMES & RESULTS Public awareness of DLD is still unsatisfactory in all three countries. Around 70% of respondents reported having heard of DLD; however, only around 20% of Croatian, 40% of Italian and 5% of Slovenian respondents provided an adequate definition of DLD. Differences in research and clinical traditions may explain the observed variations amongst the three countries. Education level was the only variable that was significantly associated with an awareness of DLD in Croatia and Italy: there, more educated people showed a higher awareness and more correct knowledge, which was not found in the Slovenian sample. Respondents generally perceived speech and language pathologists (SLPs) as the professionals responsible for recognizing DLD. Finally, people possess the highest awareness of autism spectrum disorder (ASD), while the awareness of DLD and other (neuro)developmental disorders is equally low. CONCLUSIONS & IMPLICATIONS Public awareness of DLD varies substantially among the three countries, but there is space for improvement in each of them. The findings of this study build on the existing data from the international group of collaborators, and argue for well-planned, systematic awareness-raising activities in the region. WHAT THIS PAPER ADDS What is already known on the subject DLD is one of the most common (neuro)developmental disorders, yet it is not well known to the general public. This low awareness hinders timely recognition and adequate intervention, which can have negative psychosocial and emotional consequences for affected individuals. It is known that the awareness of any disorder can depend on one's demographic characteristics, but levels of awareness of DLD are still not examined in detail. What this study adds to existing knowledge Public awareness of DLD is moderate in Croatia, Italy and Slovenia, but many individuals who report having heard of it appear to misunderstand what it actually is. Of various demographic factors tested, only education significantly influenced public awareness in Croatia and Italy, where more educated people possess greater knowledge. Moreover, respondents generally perceived SLPs as professionals responsible for recognizing DLD. What are the potential or actual clinical implications of this work? Professionals and researchers should focus on raising DLD awareness in the general public of these three countries, and may need to target different demographic groups accordingly.

Abstract
BACKGROUND The neuropsychological profile of children with sex chromosome trisomies [SCTs] is frequently characterised by delays and impairments in language development. However, no studies so far have specifically investigated their narrative competence. AIMS The aim of the study was to analyse the oral narrative competence of preschool children with SCTs due to the importance of this skill for language development and learning abilities. METHODS AND PROCEDURES Participants were 34 Italian children with SCTs one-to-one matched by age and sex to typically developing [TD] children. A storytelling task, the Narrative Competence Task, was used to assess the macrostructural and microstructural features of the children's narratives. OUTCOMES AND RESULTS Children with SCTs showed significantly lower scores than TD peers in all the narrative indices considered, except for mental state lexicon and story length in words. CONCLUSIONS AND IMPLICATIONS The problems found in narrative competence confirmed the existence of difficulties in the language development of children with SCTs. Narrative difficulties could affect these children's future learning skills and academic achievements.

Abstract
BACKGROUND Developmental language disorder (DLD) has clear functional ramifications in the areas of social competency, emotion recognition, emotional well-being and literacy skill, which have been found to persist from childhood to adolescence. These domains are important factors during the transition from primary to secondary school in typical development (TD). Nevertheless, there is a paucity of research on the transition from primary to secondary school for adolescents with DLD and low language (LL) ability. AIMS To investigate the association between psychosocial domains, literacy skill and concerns about school during the transition to secondary school for adolescents with DLD, LL and their TD peers. The first research question examined whether levels of social competency, emotion recognition, emotional well-being and literacy skill predicted school concern for the three groups. The second research question explored the longitudinal relationship between school concern and psychosocial and literacy indicators over the transition. METHODS & PROCEDURES Participants (aged 10-11 years) with DLD (n = 30), LL ((n = 29) and TD (n = 42) were recruited for this longitudinal study from eight UK primary schools. Standardized language and psychosocial assessments were administered in the spring and summer terms of the final year of primary school, and the autumn and summer terms of the first year in secondary school. OUTCOMES & RESULTS Regression analyses showed pre-transition school concern to be predicted by emotion recognition for the DLD group, by social competence and emotional well-being for the LL group, and by social competence for the TD group. Post-transition concern was predicted by emotional well-being for the LL group; with no significant predictors for the DLD/TD groups. Path analyses revealed an association between literacy skill and emotion recognition for the DLD group. A developmental cascade illustrated a relationship between social competence and emotional well-being for the TD group. CONCLUSIONS & IMPLICATIONS This study concludes that transition interventions must be differentiated according to language ability; support for DLD adolescents should focus on emotion recognition skill, provision for LL adolescents should centre on emotional well-being, and TD participants should be particularly supported in the domain of social competence in advance of the move to secondary school. Additionally, this study emphasizes the importance of the inclusion of a LL group, as their outcomes cannot be predicted using DLD/TD research. WHAT THIS PAPER ADDS What is already known on the subject There is limited research exploring the transition from primary school to secondary for adolescents with DLD or LL ability. Research on TD has highlighted vulnerable domains at this time. As these key areas are evidenced spheres of difficulty in DLD and LL, there was a strong impetus for this study. What this paper adds to existing knowledge This study reveals differences between language ability groups in the predictors of school concern both pre- and post-transition. Concerns of adolescents with DLD were predicted by emotion recognition, those of adolescents with LL were predicted by emotional well-being, and a longitudinal link between social competence and emotional well-being was evidenced for TD adolescents. What are the potential or actual clinical implications of this work? This study has implications for researchers and clinicians, as a need has been identified for a new clinical group. It also has practical implications for transition support planning for educational practitioners, families and adolescents.

Abstract
Language development disorders (in German: Sprachentwicklungsstörungen, SES) are the most common developmental disorders in childhood. In contrast to "secondary SES," "primary SES" (prevalence about 7%) are not (co-)caused by other developmental disorders or diseases. In the German modification of the International Statistical Classification of Diseases and Related Health Problems (ICD-10-GM-22), primary SES are referred to as "circumscribed developmental disorders of speech and language" (in German: USES; international previously known as Specific Language Impairment SLI), with an intelligence quotient (IQ) < 85 as an exclusion criterion, among other criteria. In ICD-11, primary SES are listed as "developmental language disorders" (DLD).German-speaking speech and language therapists would now like to replace the term "USES" with "DLD" using the diagnostic criteria proposed by the international CATALISE consortium (Criteria and Terminology Applied to Language Impairments Synthesizing the Evidence), in an effort to redefine the disorder. However, according to this conceptualization, only children with an intellectual disability (IQ < 70) would be excluded from the diagnosis. This change in the diagnostic criteria would most likely result in an increase in prevalence of DLDs. This makes the issue of early detection more important than ever. This discussion paper explains that the public health relevance of primary SES is growing and that systematic early detection examinations will play an even more important role. With early diagnosis and treatment, risks in the areas of mental health, behaviour and skill development can be mitigated.Currently, diagnosis (and therapy) are usually carried out relatively late. The way out could lie in the application of neurobiological parameters. However, this requires further studies that examine child cohorts for early indicators in a prospective longitudinal design. The formation of an early detection index from several indicators should also be considered.

Abstract
BACKGROUND Children with developmental language disorder (DLD) have deficits in verbal and non-verbal processing relative to typically developing (TD) peers, potentially reflecting difficulties in working memory, processing speed and inhibition of interference. We examined working memory in children with DLD using the serial-order-in-a-box-complex span (SOB-CS) interference-based model, which posits a time-based mechanism, free time, that governs how interference affects processing performance. AIMS (1) To determine the degree to which children with DLD and TD children differ in the amount of free time available during working memory tasks, and whether potential group differences in free time differ depending on the domain of task demands? (2) To determine the relationship between free time and interference effects on working memory accuracy in children with DLD relative to TD peers. METHODS & PROCEDURES We examined the relationship between free time and working memory in children aged 9-13 years with DLD relative to age-matched TD peers. Working memory tasks involved five conditions that varied verbal versus non-verbal task demands in an interference processing phase relative to a recall test phase. Free time was the time between response on the interference processing task and onset of the recall test phase. OUTCOMES & RESULTS DLD and TD groups did not differ in total free time in any condition. Results indicated group differences in the relationship between free time and accuracy in the conditions involving verbal recall, but not non-verbal recall. In the verbal-only condition, relatively more free time was associated with worse accuracy for the DLD group, but with better accuracy for the TD group. In the condition with verbal recall paired with non-verbal interference processing, relatively more free time was associated with better accuracy for the DLD group, but not for the TD group. CONCLUSIONS & IMPLICATIONS The overall findings suggest that free time between cognitive operations is positively associated with working memory for both verbal and non-verbal recall, except in the presence of high verbal interference for the DLD group (i.e., verbal interference paired with verbal recall). This finding may reflect poor encoding and attention under particularly challenging verbal processing demands for the DLD group. This study also demonstrates the importance of considering the interrelationships between processing speed and interference in working memory performance. WHAT THIS PAPER ADDS What is already known on the subject DLD is characterized by core deficits in verbal processing, but also deficits in non-verbal processing. Processing-based hypotheses of DLD-limited verbal working memory, slowed processing speed and inefficient inhibition-do not fully account for behavioural profiles in DLD when considered separately, yet there is evidence suggesting interrelationships among these factors. What this paper adds to existing knowledge The current study tests the key mechanism posited by a theoretical framework that has the potential to integrate these processing-based hypotheses. Our findings indicate that the effect of this mechanism differed in DLD relative to TD peers in the presence of high verbal task demands. Our findings also demonstrate the importance of considering the interrelationships among cognitive processes in children with DLD. What are the potential or actual clinical implications of this work? In practice, results from the current study suggest that children with DLD may benefit from supplementing verbal information with non-verbal information and from pauses between successive presentations of verbal information. These strategies may support their ability to maintain and act on information during verbal processing.

Examining the relationship between oral language skills and executive functions: Evidence from Greek-speaking 4-5-year-old children with and without Developmental Language Disorder. Res Dev Disabil 2022; 124:104215.

Abstract
BACKGROUND Children with Developmental Language Disorder (DLD) have been found to demonstrate low performance in Executive Functions (EFs). However, the evidence-based data is so far scarce, especially for 4-5-year-old children. Most of the existing research involves English-speaking populations, while very few studies have been carried out with non-English-speaking populations. Nevertheless, it is documented that possible differences in the language-cognition relations may exist due to the specific characteristics of each language, and studies across different languages could contribute to the above. AIMS The present study aimed to systematically investigate the profile of oral language and EF skills (verbal and nonverbal) and the way these skills are related with each other in 4-5-year-old Greek-speaking children with and without DLD. METHODS AND PROCEDURES Fifty-three 4-5-year-old children (age range: 51- 57 months) with DLD, and 62 Typically Developing (TD) peers (age range: 51- 57 months) were assessed on a standardized psychometric battery for oral language skills (phonological and morphological awareness, oral language comprehension, vocabulary knowledge, narrative speech and pragmatics) and on a series of verbal (v) and nonverbal (nv) tasks tapping EFs skills (updating-accuracy, inhibition -accuracy and reaction time-, and cognitive flexibility). OUTCOMES AND RESULTS Children with DLD demonstrated statistically significant lower performance across all oral language measures in comparison to their TD peers. Additionally, they performed significantly lower in the updating (nv) task, as well as in cognitive flexibility (v & nv) in comparison to the TD group. Further regression analyses demonstrated that updating (nv), inhibition (nv) and cognitive flexibility (v) predicted oral language comprehension in children with DLD while updating (v & nv), inhibition-reaction time (nv) and cognitive flexibility (v & nv) predicted phonological and morphological awareness, oral language comprehension, narrative speech as well as total language score in TD children. CONCLUSIONS AND IMPLICATIONS These results provide important information about the profile of oral language and EF skills in children with DLD compared to their TD peers as well as on the relationship of these skills in both groups. The findings also suggest that improving EFs skills may be a possible way for improving oral language skills in young children with DLD. Our findings are discussed in terms of their theoretical as well as practical implications regarding the diagnostic and intervention procedures for children with DLD.

Abstract
PURPOSE The current study examined language control and code-switching in bilingual children with developmental language disorder (DLD) compared to bilingual peers with typical language development (TLD). In addition, proficiency in each language and cognitive control skills were examined as predictors of children's tendency to engage in cross-speaker and intrasentential code-switching. METHOD The participants were 62 Spanish/English bilingual children, ages 4;0-6;11 (years;months), including 15 children with DLD and 47 children with TLD. In a scripted confederate dialogue task to measure language control, children took turns describing picture scenes with video partners who were monolingual speakers of English or Spanish. The Dimensional Change Card Sort indexed cognitive control, the Bilingual English Spanish Assessment assisted in identifying DLD, and parent ratings from the Inventory to Assess Language Knowledge indexed proficiency in Spanish and English. RESULTS Children with DLD were more likely to engage in cross-speaker code-switching from Spanish to English (i.e., responding in English when addressed in Spanish) than children with TLD, even when controlling for proficiency in each language. Intrasentential code-switching (i.e., integrating both languages within an utterance) did not differ between groups. Cognitive control was more associated with cross-speaker than with intrasentential code-switching. CONCLUSIONS These findings highlight the need to consider cross-speaker and intrasentential code-switching separately when seeking distinguishing features of code-switching in bilingual children with DLD. The use of increased cross-speaker code-switching by children with DLD especially with Spanish speakers highlights the need for increased support of home language use.

Abstract
The central symptom of autism spectrum disorder (ASD) is deficiency in social communication, which is generally viewed as being caused by pragmatic impairment (PI). PI is difficulty in using language appropriately in social situations. Studies have confirmed that PI is the result of neurological, cognitive, linguistic, and sensorimotor dysfunctions involving intricately intertwined factors. To elucidate the whole picture of this impairment, an approach from a multifaceted perspective fusing those factors is necessary. To this end, comprehensive PI mapping is a must, since no comprehensive mapping has yet been developed. The aim of this research is to present a model of annotation scheme development and corpus construction to efficiently visualize and quantify for statistical investigation occurrences of PI, which enables comprehensive mapping of PI in the spoken language of Japanese ASD individuals. We constructed system networks (lexicogrammatical option systems speakers make choices from) in the theoretical framework of Systemic Functional Linguistics, from which we developed an annotation scheme to comprehensively cover PI. Since system network covers all possible lexicogrammatical choices in linguistic interaction, it enables a comprehensive view of where and in what lexicogrammar PI occurs. Based on this annotation scheme, we successfully developed the Corpus of ASD + Typically Developed Spoken Language consisting of texts from 1,187 audiotaped tasks performed by 186 ASD and 106 typically developed subjects, accommodating approximately 1.07 million morphemes. Moreover, we were successful in the automatization of the annotation process by machine learning, accomplishing a 90 percent precision rate. We exemplified the mapping procedure with a focus on the spoken use of negotiating particles. Our model corpus is applicable to any language by incorporating our method of constructing the annotation scheme, and would give impetus to defining PI from a cross-linguistic point of view, which is needed because PI of ASD reflects cross-linguistic differences.

Abstract
BACKGROUND There is a clear predominance of programmes aimed at improving aspects related to language production in pupils with developmental language disorder (DLD). However, programmes aimed at improving their receptive skills are limited. AIMS The main aim was to assess the effectiveness of an intervention programme for oral language comprehension skills in preschoolers with typical development (TD) and pupils with DLD. METHODS & PROCEDURES Participants were 99 five-year-old pupils, with and without DLD, divided into four groups: two control groups (TD-C = 25; DLD-C = 25) and two experimental groups (TD-T = 24; DLD-T = 25), from schools on the Spanish island of Tenerife. The study used, as pre- and post-measures, the receptive language subtests of the CELF-4-Spanish: Concepts and Following Directions, Word Classes-Receptive and Sentence Structure, as well as two tasks assessing comprehension of paragraphs and narratives. Due to the strong link between oral comprehension skills and executive functions, working memory and semantic fluency are included in this research. The Backward Digit Span subtest of the Wechsler Intelligence Scale for Children (WISC-IV) and Semantic Fluency subtest of the Controlled Oral Word Association Test (COWAT) were used to assess working memory and semantic fluency, respectively. The intervention programme followed a multitiered system of support (MTSS) model, with 95 sessions lasting 60 min each delivered jointly by teachers and speech and language therapists, and focused on lexical-semantic, morphological, syntactic and narrative skills; inferences; verbal working memory; and semantic fluency. OUTCOMES & RESULTS The results showed, as expected, that pupils diagnosed with DLD initially performed worse on oral language comprehension and executive functions than pupils with TD. Further, the DLD-T and TD-T groups showed greater gains following the programme, especially in word classes-receptive, sentence structure, verbal working memory and semantic fluency. Finally, a significant positive correlation was found between the gains obtained by the participants in verbal working memory and semantic fluency, with the gains obtained in the three CELF-4-Spanish subtests. CONCLUSIONS & IMPLICATIONS An intervention programme applied at an early age fosters oral language comprehension skills and executive functions in pupils with DLD and TD. The intervention organized at different levels of support, following an MTSS model, showed clear progress of the DLD and TD groups in oral language comprehension and executive functions. WHAT THIS PAPER ADDS Pupils with DLD present deficits in linguistic comprehension and executive functions. There are many intervention programs focused on improving language production skills. It is also necessary to consider the skills underlying language problems in pupils with DLD. Oral language, inference, working memory and semantic fluency activities improve comprehension. A collaborative and inclusive intervention of teachers and speech language therapists. Psycholinguistic and neuropsychological skills training should become part of the academic curriculum as early as preschool age. What is already known on the subject Pupils with DLD show problems related to both comprehension and production language. However, there is a clear predominance of programs just aimed at improving aspects related to language production. Clinical implications of this study An intervention program applied at an early age fosters oral language comprehension skills and executive function in pupils with DLD. The intervention organized at different levels of support, following an adaptation of the Response Tier Intervention models, showed clear progress of the DLD in comprehension oral language and executive functions.

Language acquisition of early sequentially bilingual children is moderated by short-term memory for order in developmental language disorder: Findings from the HelSLI study. Int J Lang Commun Disord 2021; 56:907-926. [PMID: 34339103 DOI: 10.1111/1460-6984.12635] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [What about the content of this article?

Abstract
BACKGROUND The role of domain-general short-term memory (STM) in language development remains controversial. A previous finding from the HelSLI study on children with developmental language disorder (DLD) suggested that not only verbal but also non-verbal STM for temporal order is related to language acquisition in monolingual children with DLD. AIMS To investigate if a similar relationship could be replicated in a sample of sequentially bilingual children with DLD. In addition to the effect of age, the effect of cumulative second language (L2) exposure was studied. METHODS & PROCEDURES Sixty-one 4-6-year-old bilingual children with DLD and 63 typically developing (TD) bilingual children participated in a cross-sectional study conducted in their L2. Children completed novel game-like tests of visual and auditory non-verbal serial STM, as well as tests of cognitive functioning and language. Interactions of STM for order with age and exposure to L2 (Finnish) were explored as explanatory variables. OUTCOMES & RESULTS First, the improvement of non-verbal serial STM with age was faster in sequentially bilingual TD children than in bilingual children with DLD. A similar effect was observed for L2 exposure. However, when both age and exposure were considered simultaneously, only age was related to the differential growth of non-verbal STM for order in the groups. Second, only in children with DLD was better non-verbal serial STM capacity related to an improvement in language scores with age and exposure. CONCLUSIONS & IMPLICATIONS The results suggest that, as previously found in Finnish monolingual children, domain-general serial STM processing is also compromised in bilingual children with DLD. Further, similar to the monolingual findings, better non-verbal serial STM was associated with greater language improvement with age and exposure, but only in children with DLD, in the age range studied here. Thus, in clinical settings, assessing non-verbal serial STM of bilingual children could improve the detection of DLD and understanding of its non-linguistic symptoms. WHAT THIS PAPER ADDS What is already known on the subject Both phonological and non-verbal STM have been associated with DLD in monolingual and sequentially bilingual children. Monolingual children with DLD have also shown slower non-verbal serial STM development than TD children. What this study adds to existing knowledge Sequentially bilingual TD children's non-verbal serial STM improves more between ages 4 and 7 years than that of their peers with DLD, replicating a finding for monolingual children with DLD. Better non-verbal serial STM was especially associated with early receptive language development in sequentially bilingual children with DLD. L2 exposure showed largely comparable effects with age. These results support the hypothesis that a domain-general serial STM deficit is linked to DLD. What are the potential or actual clinical implications of this work? Non-verbal assessment of STM for serial order in sequentially bilingual children with DLD could benefit the development of better tailored therapeutic interventions.

Abstract
Specific reading comprehension deficit (S-RCD) and developmental language disorder (DLD) are both commonly occurring developmental disorders of language. The ways in which these disorders do and do not overlap during childhood are a matter of debate (Nation & Norbury, 2005). Moreover, in both populations, the challenges faced by individuals in adulthood are understudied. Here, we combined data across cohorts of college students, and classified individuals with only S-RCD (n = 20), only DLD (n = 55), and co-occurring S-RCD and DLD (n = 13). Individuals with good language and reading skills, who matched those with S-RCD on decoding, comprised our typical language and reading group (TD; n = 20). Beyond the measures used for classification, group-level differences were identified in sentence-level reading fluency, phonological processing, verbal working memory, and rapid automatized naming. We found that skill profiles differed across groups; however, we found no evidence of weaknesses beyond the core deficit in reading comprehension observed in those with only S-RCD. In contrast, when S-RCD co-occurs with DLD, weaknesses are observed in phonological processing, as well as reading fluency and verbal working memory. These findings suggest that some adults with S-RCD have co-occurring DLD as a core weakness. These findings, as well as differences between individuals with S-RCD and DLD, are further discussed.

Abstract
Children with familial risk (FR) of dyslexia and children with early language delay are known to be at risk for later language and literacy difficulties. However, research addressing long-term outcomes in children with both risk factors is scarce. This study tracked FR and No-FR children identified as late talkers at 2 years of age and reports development from 4;6 through 6 years. We examined the possible effects of FR-status and late talking (LT) status, respectively, on language skills at school entry, and whether FR-status moderated the associations between 4;6-year and 6-year language scores. Results indicated an effect of LT status on language at both ages, while FR status affected language skills at 6 years only. The interaction between LT and FR statuses was not significant, implying that LT status affected language skills independently of the child's FR status. A proportion of late talkers developed typical language at 6 years of age, while some FR children with typical vocabulary skills in toddlerhood had emerging developmental language disorder by school entry. FR status had a moderating effect on the association between expressive grammar at ages 4;6 and 6 years. Possible explanations for the effect of FR status on language skills are discussed. We highlight limitations in the study size and suggest how these preliminary findings can inform future research.

Abstract
PURPOSE The aim of this study was to investigate differences in language ability and emotional-behavioral problems according to the severity of social communication impairments (SCI) and restricted and repetitive behaviors (RRB) in children with autism spectrum disorders (ASD). MATERIALS AND METHODS We grouped 113 children with ASD aged 3-12 years according to the severity of SCI and RRB, and investigated language differences and emotional-behavioral problems among the severity groups. If differences in language abilities between the groups were observed, they were further subdivided to examine possible predictors of both receptive and expressive language abilities. RESULTS In cluster analyses using subdomains of the Autism Diagnostic Interview-revised, severe SCI individuals showed lower language ability than their milder counterparts, while RRB showed no differences. Receptive and expressive language in the severe SCI group was negatively predicted by social communication and social motivation, respectively. The severe RRB group showed significantly higher levels of anxiety/distress, somatic complaints, thought problems, attention problems, and aggressive behavior, while the severe SCI group was reported to be more withdrawn. CONCLUSION The results of this study suggest that the severity of SCI greatly affects language ability. In children with severe SCI, social communication and social motivation negatively predicted receptive language and expressive language, respectively. Children with severe RRB may have more emotional-behavioral problems that require active intervention.

Abstract
Purpose: Although school-age children learn most new word meanings from surrounding context, the joint roles of language ability and executive function (EF) in the word learning process remain unclear. This study examined children's acquisition of word meanings from context in relation to oral language ability and three EF skills (working memory, inhibitory control, and cognitive flexibility). Method: Typically developing school-age children completed measures of language and EF, then read and listened to short stories containing unfamiliar target words. A multiple-choice pretest-posttest measure assessed children's target word knowledge gains. Results: Regression analyses showed that language and cognitive flexibility were both related to word knowledge gains; each skill assumed greater importance among children with relative weakness in the other skill. Conclusion: Language ability and cognitive flexibility may each play a direct role in contextual word learning among school-age children, with children naturally relying on one skill if the other is weaker.

Abstract
BACKGROUND Parent-child interaction therapies are commonly used by speech and language therapists (SLTs) when providing services to young children with language learning difficulties. However, the way parents react to the demands of such interventions is clearly important, especially for those from socially disadvantaged backgrounds. Parents play a central role in the therapy process so to ensure parent engagement, and to maximize intervention effectiveness, parents' views must be considered. AIMS To explore the expectations and experiences of parents from socially disadvantaged backgrounds who had taken part in a parent-child interaction programme aimed at promoting language development in 2-3 year olds with language difficulties. METHODS & PROCEDURES The sample included parents who had a child aged 2-3 years and had attended a parent-child interaction programme to promote their child's language development. Parents were eligible to take part if they were living in the 30% most deprived areas in a city in the North of England that constituted the study site. Ten parents participated in a qualitative semi-structured face-to-face interview in the home. Framework analysis was used to analyse the interview transcripts. OUTCOMES & RESULTS Parents' expectations before taking part in parent-child interaction interventions contribute to how they may engage throughout the intervention process. Barriers include parents' uncertainty about the nature of the intervention and differing attitudes regarding intervention approaches and strategies. Facilitators during the intervention process include gaining support from other parents, reassurance from the SLT regarding their child's language development, and their own ability to support their child's language learning, as well as increased confidence in how they support their child's development. CONCLUSIONS & IMPLICATIONS Parents respond very differently to parent-child interaction intervention for children with language difficulties, depending on their expectations and attitudes towards intervention. Thus, it is critical that these different perspectives are understood by practitioners before intervention commences to ensure successful engagement. What this paper adds What is already known on this subject Parent-child interaction interventions are widely used to promote child language development. Parents play a central role in the therapy process of such interventions, so to maximize effectiveness, parents must be appropriately 'engaged' in that intervention. This involves attending, fully participating and having appropriate attitudinal and/or emotional involvement. The reciprocal nature of engagement means that parents are more likely to become engaged in intervention over time when they are supported by their SLT. What this paper adds to existing knowledge Parental expectations about the intervention process vary considerably and often need to be negotiated before the start of intervention. Reassurance and supporting positive attitudes to co-working with their SLT may be particularly important for families living with social disadvantage. Supporting parent engagement in parent-child interaction programmes can contribute to the parents' capability to continue implementing language-promoting strategies outside the intervention context and beyond the end of therapy. What are the potential or actual clinical implications of this work? Parents have different expectations regarding programme involvement. Therefore, having a two-way, open dialogue between parents and SLTs from the beginning is clearly important, not only as a way of sharing information but also to build on parents' understanding of what the intervention will involve and trust that the SLT will be able to deliver the intervention in collaboration with the parent. SLTs can enhance parent engagement by supporting parents to feel confident and providing reassurance in terms of their child's development and how they can support their child's language learning.

Abstract
We investigated production of lexical stress in children with and without autism spectrum disorders (ASD), all monolingual Italian speakers. The mean age of the 16 autistic children was 5.73 years and the mean age of the 16 typically developing children was 4.65 years. Picture-naming targets were five trisyllabic words that began with a weak-strong pattern of lexical stress across the initial two syllables (WS: matita) and five trisyllabic words beginning with a strong-weak pattern (SW: gomito). Acoustic measures of the duration, fundamental frequency, and intensity of the first two vowels for correct word productions were used to calculate a normalised Pairwise Variability Index (PVI) for WS and SW words. Results of acoustic analyses indicated no statistically significant group differences in PVIs. Results should be interpreted in line with the exploratory nature of this study. We hope this study will encourage additional cross-linguistic studies of prosody in children's speech production.

Abstract
BACKGROUND Children with developmental language disorder (DLD) are at higher risk of poorer mental health compared with children without DLD. There are, however, considerable individual differences that need to be interpreted, including the identification of protective factors. AIMS Pathways from the early language and communication environment (ELCE, 1-2 years) to internalizing (peer and emotional problems) and externalizing (conduct problems and hyperactivity) problems in middle childhood (11 years) were mapped using structural equation modelling. Specifically, the role of indirect pathways via social skills (friendships, play and prosociality) in childhood (7-9 years) was investigated. METHODS & PROCEDURES Secondary analysis of existing data from the Avon Longitudinal Study of Parents and Children (ALSPAC) was undertaken. The study sample consisted of 6531 children (394 with DLD). OUTCOMES & RESULTS The pathways from the ELCE to internalizing and externalizing problems were similar for children with and without DLD. For both groups, a positive ELCE was associated with more competent social play and higher levels of prosociality in childhood, which in turn were associated with fewer externalizing problems in middle childhood. Furthermore, better friendships and higher levels of prosociality in childhood were both associated with fewer internalizing problems in middle childhood. CONCLUSIONS & IMPLICATIONS A child's ELCE is potentially important not only for the development of language but also for social development. Furthermore, in the absence of adequate language ability, play and prosocial behaviours may allow children with DLD to deploy, practise and learn key social skills, thus protecting against externalizing problems. We suggest that consideration be given to play- and prosociality-based educational and therapeutic services for children with DLD. What this paper adds What is already known on this subject On the whole, children with DLD tend to have poorer mental health compared with their unaffected peers. There are, however, considerable differences and poor outcomes are not inevitable. What this study adds to the existing knowledge We demonstrate that children's ECLE is important for the development of social play behaviours and prosociality. Whilst children with DLD tend to have less competent social play and lower levels of prosociality compared with their unaffected peers, those with more competent social play and higher levels of prosociality are likely to have fewer externalizing problems later in childhood. We speculate that in the absence of adequate structural language ability, play and prosocial behaviours allow children with DLD to deploy, practise and learn key relationship skills, alongside behavioural and emotional regulation skills, thus protecting against externalizing problems. What are the potential or actual clinical implications of this work? Understanding the relationships among play, prosociality and externalizing problems may pave the way for play- and prosociality-based interventions in children with DLD. This may be particularly appealing for practitioners as such interventions capitalize on one of the most intuitive means of learning in childhood: play with friends. The likelihood of acceptability and engagement with such interventions may be higher in children than for traditional adult-led, paper-and-pencil activities.

Abstract
BACKGROUND Studies estimate that 30% of individuals with autism are minimally verbal. Understanding what factors predict longer-term expressive development in children with language delays is critical to inform identification and treatment of those at-risk for persistent language impairments. The present study examined predictors of expressive language development in language-delayed preschoolers followed through later school-age and young adulthood. METHODS Children using single words or less on the Autism Diagnostic Observation Schedule (ADOS) at approximately 3 years old were drawn from the Early Diagnosis (EDX) and Pathways in ASD longitudinal cohorts. Age-3 predictors of Age-19 ADOS language level were identified using Classification and Regression Trees (CART) in the EDX sample. Linear mixed models examined the effects of CART-identified predictors on Vineland expressive communication (VExp) trajectories from Age-3 to Age-19. The same linear mixed models were examined in the Pathways sample, identifying predictors of VExp from ages 3 to 10.5 years. RESULTS Significantly delayed fine motor skills (T-score < 20) was the strongest CART predictor of Age-19 language. In the linear mixed models, time, Age-3 fine motor skills and initiation of joint attention (IJA) predicted VExp trajectories in the EDX sample, even when controlling for Age-3 visual receptive abilities. In the Pathways sample, time and Age-3 fine motor skills were significant predictors of VExp trajectories; IJA and cognitive skills were not significant predictors. CONCLUSIONS Marked deficits in fine motor skills may be a salient proxy marker for identifying language-delayed children with ASD who are at risk for persistent language impairments. This finding adds to the literature demonstrating a relation between motor and language development in ASD. Investigating individual skill areas (e.g., fine motor and nonverbal problem-solving skills), rather than broader indices of developmental level (e.g., nonverbal IQ) may provide important cues to understanding longer-term language outcomes that can be targeted in early intervention.

Abstract
The aim of the current study was to examine microstructural differences in white matter relevant to procedural and declarative memory between adolescents/young adults with and without Developmental Language Disorder (DLD) using diffusion tensor imaging (DTI). The findings showed atypical age-related changes in white matter structures in the corticostriatal system, in the corticocerebellar system, and in the medial temporal region in individuals with DLD. Results highlight the importance of considering the age factor in research on DLD. Future studies are needed to examine the developmental relationship between long-term memory and individual differences in language development and learning.

Abstract
BACKGROUND/OBJECTIVE The effects of otitis media on the function of the central auditory nervous system in different populations is unknown. Understanding how the history of otitis media affects children from different nations will guide health professionals worldwide on the importance of adequate auditory stimulus in childhood. For this reason, the aim of the present study was to investigate the long-term auditory effects of middle ear disease on temporal processing and P300 in two different populations of children: Australian and Brazilian. METHODS Temporal processing tests (Frequency Pattern Tests-FPT and Gaps in noise-GIN) and P300 were measured in 68 Brazilian and Australian children, aged between 8 to 14 years. The Brazilian otitis media group (BrOM) and Australian otitis media group (AusOM) consisted of 20 children each who had a documented history of otitis media. Control groups of 14 children (BrControl and AusControl) were also recruited from each country, all with no documented history of otitis media. RESULTS The BrOM group showed significantly poorer performance (p<0.001) for FPT and the GIN compared to BrControl. The P300 response showed significantly longer mean latencies (p = 0.02) compared to BrControls. The AusOM group also showed significant delayed latency of P300 (p = 0.04) compared to the AusControl. The FPT showed significantly poorer performance (p = 0.04) compared to AusControls. The two otitis media groups showed no significant differences between each other on P300. Significant differences were seen however in temporal processing tests performance between the two cohorts for the otitis media groups. The BrOM group had significantly poorer responses (p<0.001) for FPT and GIN compared to the AusOM group. CONCLUSIONS These findings support that although differences exist between BrOM and AusOM groups, otitis media can be demonstrated to affect the underlying mechanisms of the P300 measures and behavioral auditory responses in two different populations of children.

Abstract
Some theories of Developmental Language Disorder (DLD) explain the linguistic deficits observed in terms of limitations in non-linguistic cognitive systems such as working memory. The goal of this research is to clarify the relationship between working memory and the processing of complex sentences by exploring the performance of 28 French-speaking children with DLD aged five to fourteen years and 48 typically developing children of the same age in memory and linguistic tasks. We identified predictive relationships between working memory and the comprehension and repetition of complex sentences in both groups. As for syntactic measures in spontaneous language, it is the complex spans that explain the major part of the variance in the control children. In children with DLD, however, simple spans are predictive of these syntactic measures. Our results thus reveal a robust relationship between working memory and syntactic complexity, with clinical implications for the treatment of children with DLD.

Abstract
BACKGROUND Turkish has a rich system of noun suffixes, and although its complex suffixation system may seem daunting, it can actually present a learning opportunity for children. Despite its unique features, Turkish has not been studied extensively, especially in the case of children with language deficits, such as developmental language disorder (DLD). Most of the extant studies are focused on bilingual children, and the results are somewhat mixed. AIMS To focus on the noun morphology system of Turkish-speaking preschoolers with DLD and compare their use with that of two groups of typically developing (TD) children. Moreover, to investigate the nature of their noun suffix errors in detail. METHODS & PROCEDURES We report data from a total of 80 monolingual children, 40 children with DLD (age range = 4;0-7;10), 20 TD age-matched children (4;0-7;3) and 20 younger mean length of utterance (MLU)-matched children (2;0-4;3). The data for this study came from language samples obtained from children in individual clinical assessment sessions. OUTCOMES & RESULTS The children with DLD made less use of noun suffixes than both the younger and the age-matched TD children. The use of the unmarked (nominative case) form in place of an overt suffix was the most likely error by all groups. Suffix-change alternations required beyond vowel harmony seemed to pose real problems for these children. CONCLUSIONS & IMPLICATIONS These results suggest that even when a language appears to provide significant advantages for the learning of noun morphology, children with DLD do not succeed in closing the gap. Certain factors such as morphophonological changes beyond vowel harmony, multiple allomorphs for the same suffix type and accusative suffixes that are not uniformly applied in the adult input were found to be significant predictors of the DLD group's difficulty with noun suffixes. Because these same factors can serve as characteristics of other languages, a child's difficulties might seem to be language specific (e.g., a particular allomorph in the language), but may actually be based on a broader difficulty (e.g., dealing with multiple allomorphs for the same suffix). Accordingly, factors that transcend a single language should be considered during clinical assessment and therapy. What this paper adds? What is already known on this subject? The current literature on the use of noun suffixes by Turkish-speaking children with DLD is very limited. Although Turkish is often described as a learner-friendly language, the degree to which children with DLD enjoy these learning benefits is unknown. What does this paper add to existing knowledge? Turkish children with DLD are less accurate in noun suffixes than both age-matched and younger control groups. For this group, the central problem seems to be increased complexity in morphophonology rather than difficulty with suffixation more generally. What are some of the clinical applications of this study? For clinicians who work with Turkish-speaking children with DLD, priority should be given to morphophonology. These children would benefit from treatment that focuses on how to attach different allomorphs to different open-class words. Because factors such as morphophonological complexity operate in other languages, the findings have broader clinical implications. In particular, regardless of the target language, clinicians should consider the possibility that these broader factors, rather than language-specific details, are the basis for a child's difficulty.

Abstract
In the present study, language performance on standardized assessments (e.g., overall verbal performance, receptive and expressive vocabulary) and spontaneous language produced in play was compared between preschool-aged boys with autism spectrum disorder (nASD, n = 25) and boys with fragile X syndrome (FXS, n = 16). At the group-level, we observed weaknesses in the language skills of boys with nASD relative to those with FXS (e.g., when considering raw score performance, standard score performance relative to nonverbal cognitive skills, frequency of talk in play), after controlling for nonverbal IQ and ASD symptom severity. Moreover, although individually most children in both groups demonstrated language delays relative to CA-expectations, language delays relative to nonverbal level-expectations were more common in boys with nASD.

Abstract
Purpose The purpose of this study was to identify which morphological markers have the best diagnostic accuracy to identify developmental language disorders (DLD) in monolingual Spanish-speaking children. Method The participants in this study included 50 Spanish-speaking monolingual children with (n = 25) and without (n = 25) DLD. Data collection took place in Mexico. Children were administered a comprehensive elicitation task that set up felicitous contexts to produce morphological structures previously identified as problematic for Spanish-speaking children with DLD: articles, direct object pronouns, adjectives, plurals, verb conjugations, and the subjunctive in Spanish. Results Statistically significant group differences between children with and without DLD were found for all morphological structures examined but plurals. Logistic regression analyses suggested that a model that included clitic and verbs was the best model to uniquely predict group membership. This model showed sensitivity of 96% and specificity of 80%. Conclusion Clitics and verbs should be considered morphological markers of DLD in monolingual Spanish-speaking children.

Abstract
BACKGROUND There is limited evidence concerning the longer term language, literacy and cognitive skills of young adults with developmental language disorder (DLD). Studies that exist suggest continuing difficulties with language and reading, but abilities may change over time. AIMS This study aimed to examine the language, literacy and cognitive skills of young adults with and without DLD. METHODS & PROCEDURES Data were used from the Manchester Language Study data set which was collected from a group of young adults with DLD (recruited originally at 7 years of age from language units-specialist educational resource bases). Participants were assessed on their language, literacy and cognitive functioning when they were aged 24. A comparison group of age-matched peers (AMPs; also 24 years old) were also assessed. For language and cognition, change in scores between 16 and 24 years was also available for analysis. Finally, self-rated measures of literacy difficulties were taken at 24 years for functional reading and writing. OUTCOME & RESULTS The results indicate that the young people with DLD in this sample continue to perform more poorly as a group on formal oral and written language tests. A small but significant minority of young adults with DLD also report functional reading and writing difficulties compared with AMPs despite reporting reading as often as their peer group. Compared with scores at 16 years of age, this subsample now appears to show slightly less risk of non-verbal IQ difficulties, showing small but significant 'catch-up' to AMPs. CONCLUSIONS & IMPLICATIONS These preliminary data suggest that at least some individuals with DLD experience marked linguistic difficulties in adulthood, and that the pathways of language, literacy and cognition are not entirely parallel for this group. Continued support and awareness of challenges for young adults with DLD may be useful. What this paper adds What is already known on the subject It is known that DLD is long term and persists into adulthood. There has recently been a body of work reporting on the well-being of this population, as well as their employment, financial status and driving ability. However, there is very little information about language, literacy and cognitive skills beyond school age. What this paper adds to existing knowledge This study presents data on language, literacy and cognition from a large cohort of young adults with DLD and their AMPs. In this sample, a large proportion of participants score low on language, with fewer scoring as impaired on literacy and cognition. A significant minority reports difficulties in functional reading. Preliminary analysis appears to suggest that while language development remains depressed, non-verbal cognitive skills show some catch up over time. What are the potential or actual clinical implications of this work? Increased awareness and continued support for language, literacy and cognition may be useful for young adults with DLD.

Abstract
BACKGROUND Children with dyslexia and/or developmental language disorder (hereafter children with DDLD) have been reported to retrieve fewer words than their typically developing (TD) peers in semantic fluency tasks. It is not known whether this retrieval difficulty can be attributed to the semantic structure of their lexicon being poor or, alternatively, to words being retrieved more slowly despite semantic structure being intact. AIMS To test two theoretical models that could potentially account for retrieval difficulties in semantic fluency tasks, namely, the Poor Lexical-Semantic Structure Model and the Slow-Retrieval Model. Both models predict that children with DDLD will retrieve fewer items compared with TD children. However, while the Poor Lexical-Semantic Structure Model predicts a less sophisticated network of semantic connections between words in the lexicon, as evidenced by smaller clusters of related items in children with DDLD, the Slow-Retrieval Model predicts intact inter-item associations in the lexicon, as evidenced by the two groups' clusters being of a similar size. The groups' semantic fluency performance was therefore compared. How semantic fluency performance related to children's language, literacy, and phonological skills was also investigated. METHODS & PROCEDURES A total of 66 children with DDLD aged 7-12 years and 83 TD children aged 6-12 years, all monolingual Greek speakers, were tested on semantic fluency, using the categories 'animals', 'foods' and 'objects from around the house'. The numbers of correct and incorrect responses, clusters and switches, and the average cluster size were computed. Children were also assessed on non-verbal IQ, language, literacy and phonological tasks. OUTCOMES & RESULTS In both groups, productivity in semantic fluency tasks correlated strongly with the numbers of clusters and switches, but not with average cluster size. The DDLD group produced significantly fewer correct responses and fewer clusters compared with the TD group, but the two groups showed similar switching and average cluster size. Children's language, literacy and phonological skills significantly predicted the number of correct responses produced, beyond the significant effect of age. CONCLUSIONS & IMPLICATIONS We conclude that poorer semantic fluency performance in children with DDLD results not from a lexicon with poor semantic structure, but rather from slower retrieval processes from a lexicon with intact semantic structure. The underlying causes of slow lexical retrieval still need further investigation.
