To develop a parental questionnaire for screening children with delayed language development in primary care settings. Ramathibodi Language Development (RLD) questionnaire was developed and completed by groups of 40 typically developing children age 18 to 30 months old and 30 children with delayed language development. The mean score was significantly lower in the delay language group (6.7 ± 1.9), comparing with the typically developing group (9.6 ± 0.7). The optimal ROC curve cut-off score was 8 with corresponding sensitivity and specificity were 98% and 72%, respectively. The corresponding area under the curve was 0.96 (95% CI = 0.92-0.99). The RLD questionnaire was the promising language developmental screening instrument that easily utilized in well-child examination settings.

In this study, the authors aimed at gaining understanding on the associations of different types of early language and communication profiles with later self-regulation skills by using longitudinal data from toddler age to kindergarten age. Children with early language profiles representing expressive delay, broad delay (i.e., expressive, social, and/or symbolic), and typical language development were compared in domains of kindergarten-age executive and regulative skills (attentional/executive functions, regulation of emotions and behavioral activity, and social skills) assessed with parental questionnaires. Children with delay in toddler-age language development demonstrated poorer kindergarten-age self-regulation skills than children with typical early language development. Broad early language delays were associated with compromised social skills and attentional/executive functions, and early expressive delays were associated with a generally lower level of kindergarten-age executive and regulative skills. Regression analyses showed that both earlier and concurrent language had an effect especially on the attentional/executive functions. The findings suggest that different aspects of toddler-age language have differential associations with later self-regulation. Possible mechanisms linking early language development to later self-regulative development are discussed.

Abstract Early language delay has often been associated with atypical language/literacy development. Neuroimaging studies further indicate functional disruptions during language and print processing in school-age children with a retrospective report of early language delay. Behavioral data of 114 5-year-olds with a retrospective report of early language delay in infancy (N = 34) and those without (N = 80) and with a familial risk for dyslexia and those without are presented. Behaviorally, children with a retrospective report of early language delay exhibited reduced performance in language/reading-related measures. A voxel-based morphometry analysis in a subset (N = 46) demonstrated an association between reduced gray matter volume and early language delay in left-hemispheric middle temporal, occipital, and frontal regions. Alterations in middle temporal cortex in children with a retrospective report of early language delay were observed regardless of familial risk for dyslexia. Additionally, while children with isolated familial risk for dyslexia showed gray matter reductions in temporoparietal and occipitotemporal regions, these effects were most profound in children with both risk factors. An interaction effect of early language delay and familial risk was revealed in temporoparietal, occipital, and frontal cortex. Our findings support a cumulative effect of early behavioral and genetic risk factors on brain development and may ultimately inform diagnosis/treatment. PMID:26585334

To compare and analyze the clinical characteristics of children with delayed language acquisition due to two different diagnoses, which were specific language impairment (SLI, a primarily delayed language development) and global developmental delay (GDD, a language delay related to cognitive impairment). Among 1,598 children who had visited the developmental delay clinic from March 2005 to February 2011, 467 children who were diagnosed with GDD and 183 children who were diagnosed with SLI were included in this study. All children were questioned about past, family, and developmental history, and their language competences and cognitive function were assessed. Some children got electroencephalography (EEG), in case of need. The presence of the perinatal risk factors showed no difference in two groups. In the children with GDD, they had more delayed acquisition of independent walking and more frequent EEG abnormalities compared with the children with SLI (p<0.01). The positive family history of delayed language development was more prevalent in children with SLI (p<0.01). In areas of language ability, the quotient of receptive language and expressive language did not show any meaningful statistical differences between the two groups. Analyzing in each group, the receptive language quotient was higher than expressive language quotient in both group (p<0.01). In the GDD group, the Bayley Scales of Infant Development II (BSID-II) showed a marked low mental and motor quotient while the Wechsler Intelligence Scale showed low verbal and nonverbal IQ. In the SLI group, the BSID-II and Wechsler Intelligence Scale showed low scores in mental area and verbal IQ but sparing motor area and nonverbal IQ. The linguistic profiles of children with language delay could not differentiate between SLI and GDD. The clinicians needed to be aware of these developmental issues, and history taking and clinical evaluation, including cognitive assessment, could be helpful to diagnose adequately and set the treatment plan for each child.

Speech and language development in cognitively delayed children with cochlear implants.
Holt, Rachael Frush; Kirk, Karen Iler
2005-04-01
The primary goals of this investigation were to examine the speech and language development of deaf children with cochlear implants and mild cognitive delay and to compare their gains with those of children with cochlear implants who do not have this additional impairment. We retrospectively examined the speech and language development of 69 children with pre-lingual deafness. The experimental group consisted of 19 children with cognitive delays and no other disabilities (mean age at implantation = 38 months). The control group consisted of 50 children who did not have cognitive delays or any other identified disability. The control group was stratified by primary communication mode: half used total communication (mean age at implantation = 32 months) and the other half used oral communication (mean age at implantation = 26 months). Children were tested on a variety of standard speech and language measures and one test of auditory skill development at 6-month intervals. The results from each test were collapsed from blocks of two consecutive 6-month intervals to calculate group mean scores before implantation and at 1-year intervals after implantation. The children with cognitive delays and those without such delays demonstrated significant improvement in their speech and language skills over time on every test administered. Children with cognitive delays had significantly lower scores than typically developing children on two of the three measures of receptive and expressive language and had significantly slower rates of auditory-only sentence recognition development. Finally, there were no significant group differences in auditory skill development based on parental reports or in auditory-only or multimodal word recognition. The results suggest that deaf children with mild cognitive impairments benefit from cochlear implantation. Specifically, improvements are evident in their ability to perceive speech and in their reception and use of language. However, it may be reduced relative to their typically developing peers with cochlear implants, particularly in domains that require higher level skills, such as sentence recognition and receptive and expressive language. These findings suggest that children with mild cognitive deficits be considered for cochlear implantation with less trepidation than has been the case in the past. Although their speech and language gains may be tempered by their cognitive abilities, these limitations do not appear to preclude benefit from cochlear implant stimulation, as assessed by traditional measures of speech and language development.

Parental and speech and language therapist (SLT) explanatory models may affect engagement with speech and language therapy, but there has been dearth of research in this area. This study investigated parents' and SLTs' views about language development, delay and intervention in pre-school children with language delay. The aims were to describe, explore and explain the thoughts, understandings, perceptions, beliefs, knowledge and feelings held by: a group of parents from East Manchester, UK, whose pre-school children had been referred with suspected language delay; and SLTs working in the same area, in relation to language development, language delay and language intervention. A total of 24 unstructured interviews were carried out: 15 with parents whose children had been referred for speech and language therapy and nine with SLTs who worked with pre-school children. The interviews were transcribed verbatim and coded using Atlas/ti. The data were analysed, subjected to respondent validation, and grounded theories and principled descriptions developed to explain and describe parents' and SLTs' beliefs and views. Parent and SLT data are presented separately. There are commonalities and differences between the parents and the SLTs. Both groups believe that language development and delay are influenced by both external and internal factors. Parents give more weight to the role of gender, imitation and personality and value television and videos, whereas the SLTs value the 'right environment' and listening skills and consider that health/disability and socio-economic factors are important. Parents see themselves as experts on their child and have varied ideas about the role of SLTs, which do not always accord with SLTs' views. The parents and SLTs differ in their views of the roles of imitation and play in intervention. Parents typically try strategies before seeing an SLT. These data suggest that parents' ideas vary and that, although parents and SLTs may share some views, there are some important differences. These views have implications for the provision of appropriate services. Although this is a small sample from one group in the UK, the results indicate the need to investigate the views of other groups of parents.

To describe the concurrent validity and classification accuracy of 2 Spanish parent surveys of language development, the Spanish Ages and Stages Questionnaire (ASQ; Squires, Potter, & Bricker, 1999) and the Pilot Inventario-III (Pilot INV-III; Guiberson, 2008a). Forty-eight Spanish-speaking parents of preschool-age children participated. Twenty-two children had expressive language delays, and 26 had typical language development. The parents completed the Spanish ASQ and the Pilot INV-III at home, and the Preschool Language Scale, Fourth Edition: Spanish Edition (PLS-4 Spanish; Zimmerman, Steiner, & Pond, 2002) was administered to the children at preschool centers. The Spanish ASQ and Pilot INV-III were significantly correlated with the PLS-4 Spanish, establishing concurrent validity. On both surveys, children with expressive language delays scored significantly lower than children with typical development. The Spanish ASQ demonstrated unacceptably low sensitivity (59%) and good specificity (92%), while the Pilot INV-III demonstrated fair sensitivity (82%) and specificity (81%). Likelihood ratios and posttest probability revealed that the Pilot INV-III may assist in detection of expressive language delays, but viewed alone it is insufficient to make an unconditional screening determination. Results suggest that Spanish parent surveys hold promise for screening language delay in Spanish-speaking preschool children; however, further refinement of these tools is needed.

Speech and language delay in two children: an unusual presentation of hyperthyroidism.
Sohal, Aman P S; Dasarathi, Madhuri; Lodh, Rajib; Cheetham, Tim; Devlin, Anita M
2013-01-01
Hyperthyroidism is rare in pre-school children. Untreated, it can have a profound effect on normal growth and development, particularly in the first 2 years of life. Although neurological manifestations of dysthyroid states are well known, specific expressive speech and language disorder as a presentation of hyperthyroidism is rarely documented. Case reports of two children with hyperthyroidism presenting with speech and language delay. We report two pre-school children with hyperthyroidism, who presented with expressive speech and language delay, and demonstrated a significant improvement in their language skills following treatment with anti-thyroid medication. Hyperthyroidism must be considered in all children presenting with speech and language difficulties, particularly expressive speech delay. Prompt recognition and early treatment are likely to improve outcome.

This study aimed to compare imitation skills in children with autism spectrum disorder, and age-matched typically developing children and children with developmental delay, as well as to examine the association between imitation skills, and receptive and expressive language development in children with autism spectrum disorder. Imitation skills in children with autism spectrum disorder (n=18), and age-matched children with developmental delay (n=15) and typically developing children (n= 16) were assessed using the Motor Imitation Scale and Imitation Battery, and the differences in mean imitation scores between the groups were examined. Receptive language and expressive language development in the children with autism spectrum disorder were assessed using the Turkish Communicative Development Inventory (TCDI), and their association with imitation scores was explored. The children with autism spectrum disorder had significantly lower imitation scores than the children with developmental delay and typically developing children; however, there wasn't a significant difference in imitation scores between the children with developmental delay and typically developing children. A significant association between imitation scores, and receptive and expressive language development was observed in the children with autism spectrum disorder. The present findings indicate that deficient imitation skills are a distinctive feature of children with autism spectrum disorder and that imitation skills play a crucial role in children's language development.

Guanidinoacetate N-methyltransferase (GAMT) deficiency is a defect in the biosynthesis of creatine (Cr). So far, reports have not focused on the description of developmental abilities in this disorder. Here, we present the result of formal testing of developmental abilities in a GAMT-deficient patient. Our patient, a 3-year-old boy with GAMT deficiency, presented clinically with a severe language production delay and nearly normal nonverbal development. Treatment with oral Cr supplementation led to partial restoration of the cerebral Cr concentration and a clinically remarkable acceleration of language production development. In contrast to clinical observation, formal testing showed a rather harmonic developmental delay before therapy and a general improvement, but no specific acceleration of language development after therapy. From our case, we conclude that in GAMT deficiency language delay is not always more prominent than delays in other developmental areas. The discrepancy between the clinical impression and formal testing underscores the importance of applying standardized tests in children with developmental delays. Screening for Cr deficiency by metabolite analysis of body fluids or proton magnetic resonance spectroscopy of the brain deficiency should be considered in any child with global developmental delay/mental retardation lacking clues for an alternative etiology.

Failure to recognize and intervene early in speech and language delays can lead to multifaceted and potentially severe consequences for early child development and later literacy skills. While routine evaluations of speech and language during well-child visits are recommended, there is no standardized (office) approach to facilitate this. Furthermore, extensive wait times for speech and language pathology consultation represent valuable lost time for the child and family. Using speech and language expertise, and paediatric collaboration, key content for an office-based tool was developed. early and accurate identification of speech and language delays as well as children at risk for literacy challenges; appropriate referral to speech and language services when required; and teaching and, thus, empowering parents to create rich and responsive language environments at home. Using this tool, in combination with the Canadian Paediatric Society's Read, Speak, Sing and Grow Literacy Initiative, physicians will be better positioned to offer practical strategies to caregivers to enhance children's speech and language capabilities. The tool represents a strategy to evaluate speech and language delays. It depicts age-specific linguistic/phonetic milestones and suggests interventions. The tool represents a practical interim treatment while the family is waiting for formal speech and language therapy consultation.

Fragile X syndrome (FXS) is associated with significant language and communication delays, as well as problems with attention. This study investigated early language abilities in infants and toddlers with FXS (n = 13) and considered visual attention as a predictor of those skills. We found that language abilities increased over the study period of 9 to 24 months with moderate correlations among language assessments. In comparison to typically developing infants (n = 11), language skills were delayed beyond chronological age- and developmental level-expectations. Aspects of early visual attention predicted later language ability. Atypical visual attention is an important aspect of the FXS phenotype with implications for early language development, particularly in the domain of vocabulary. PMID:25715182

2012-01-01
A trial parent-focused early intervention (PFEI) programme for children with delayed language development is reported in which current research evidence was translated and applied within the constraints of available of clinical resources. The programme, based at a primary school, was run by a speech-language pathologist with speech-language pathology students. To investigate the changes in child language development and parent and child interactions following attendance at the PFEI. Eighteen parents and their children attended six, weekly group sessions in which parents were provided with strategies to maximize language learning in everyday contexts. Pre- and post-programme assessments of vocabulary size and measures of parent-child interaction were collected. Parents and children significantly increased their communicative interactions from pre- to post-treatment. Children's expressive vocabulary size and language skills increased significantly. Large-effect sizes were observed. The positive outcomes of the intervention programme contribute to the evidence base of intervention strategies and forms of service delivery for children at risk of language delay. © 2012 Royal College of Speech and Language Therapists.

Preterm infants are at greater risk of language delay. Early identification of language delay is essential to improve functional outcome in these children. To examine the concurrent validity of Rescorla's Language Development Survey and the Bayley Scales of Infant and Toddler Development (Bayley-III) at 18months corrected age in preterm infants. Test accuracy study. 189 preterm infants born <29weeks were assessed at 18months. The Language Development Survey, a parent-reported screening instrument, was administered in French concurrently with the Language Scales of the Bayley-III. Receiver-Operating-Characteristics curves were used to determine optimal cut-off score on the Language Development Survey to identify Bayley-III score <85. Sensitivity, specificity, positive and negative predictive values, and κ coefficient were calculated. Using Rescorla's original cut-off scores of ≤10 words for boys and ≤24 for girls, sensitivity was 76% and 88% for boys and girls, respectively, and specificity was 73% and 52% for boys and girls, respectively, in identifying language delay as per the Bayley-III. The optimal threshold was ≤10 words for both boys and girls. In girls, lowering the cut-off score decreased sensitivity (79%), but improved specificity (82%), thus lowering the number of false-positives. Our findings support using the Language Development Survey as an expressive language screener in preterm infants. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Early language experience is essential for the development of a high level of linguistic proficiency in adulthood and in a recent functional Magnetic Resonance Imaging (fMRI) experiment, we showed that a delayed acquisition of a first language results in changes in the functional organization of the adult brain (Mayberry et al., 2011). The present study extends the question to explore if delayed acquisition of a first language also modulates the structural development of the brain. To this end, we carried out anatomical MRI in the same group of congenitally deaf individuals who varied in the age of acquisition of a first language, American Sign Language -ASL (Mayberry et al., 2011) and used a neuroanatomical technique, Voxel-Based Morphometry (VBM), to explore changes in gray and white matter concentrations across the brain related to the age of first language acquisition. The results show that delayed acquisition of a first language is associated with changes in tissue concentration in the occipital cortex close to the area that has been found to show functional recruitment during language processing in these deaf individuals with a late age of acquisition. These findings suggest that a lack of early language experience affects not only the functional but also the anatomical organization of the brain. Copyright © 2012 Elsevier Inc. All rights reserved.

Children from low-income families are at increased risk for significant behavioral and language problems. Early identification of these problems is essential for effective intervention. The purpose of the present study was to use multiple behavioral assessments to examine the behavioral profiles of sixty 3- and 4-year-old children from low-income families enrolled in Head Start programs and to compare the behavior characteristics of 32 children with language delays with those of 28 children with typical language development. Teachers completed the Child Behavior Checklist/Caregiver-Teacher Report Form/2-5 (CTRF; T. M. Achenbach, 1997) and the Social Skills Rating System (SSRS; F. M. Gresham and S. N. Elliott, 1990), and children were observed in the classrooms during structured and unstructured activities. Children with language delays exhibited more problem behaviors and poorer social skills on some of the observational measures than did children with typical language development, as predicted, but not on all.

This study examined vocal coordination during mother-infant interactions in the infant siblings (high risk infants; HR) of children with autism spectrum disorder (ASD), a population at heightened risk for developing language delays. Vocal coordination between mothers and HR infants was compared to a group of low risk (LR; no first- or second-degree relative with ASD) dyads, and used to predict later language development. Nine-month-old infants were videotaped at home playing with their mothers, and interactions were coded for the frequency and timing of vocalizations. Percent infant simultaneous speech was predictive of later language delay (LD), and dyads with LD infants were less coordinated with one another in average latency to respond than dyads with non-delayed (ND) infants. The degree of coordination between mothers and infants on this variable predicted a continuous measure of language development in the third year. This research underscores the importance of understanding early development in the context of interaction. PMID:26345517

Delayed development of neural language organization in very preterm born children.
Mürner-Lavanchy, Ines; Steinlin, Maja; Kiefer, Claus; Weisstanner, Christian; Ritter, Barbara Catherine; Perrig, Walter; Everts, Regula
2014-01-01
This study investigates neural language organization in very preterm born children compared to control children and examines the relationship between language organization, age, and language performance. Fifty-six preterms and 38 controls (7-12 y) completed a functional magnetic resonance imaging language task. Lateralization and signal change were computed for language-relevant brain regions. Younger preterms showed a bilateral language network whereas older preterms revealed left-sided language organization. No age-related differences in language organization were observed in controls. Results indicate that preterms maintain atypical bilateral language organization longer than term born controls. This might reflect a delay of neural language organization due to very premature birth.

Infants with Williams syndrome detect statistical regularities in continuous speech.
Cashon, Cara H; Ha, Oh-Ryeong; Graf Estes, Katharine; Saffran, Jenny R; Mervis, Carolyn B
2016-09-01
Williams syndrome (WS) is a rare genetic disorder associated with delays in language and cognitive development. The reasons for the language delay are unknown. Statistical learning is a domain-general mechanism recruited for early language acquisition. In the present study, we investigated whether infants with WS were able to detect the statistical structure in continuous speech. Eighteen 8- to 20-month-olds with WS were familiarized with 2min of a continuous stream of synthesized nonsense words; the statistical structure of the speech was the only cue to word boundaries. They were tested on their ability to discriminate statistically-defined "words" and "part-words" (which crossed word boundaries) in the artificial language. Despite significant cognitive and language delays, infants with WS were able to detect the statistical regularities in the speech stream. These findings suggest that an inability to track the statistical properties of speech is unlikely to be the primary basis for the delays in the onset of language observed in infants with WS. These results provide the first evidence of statistical learning by infants with developmental delays. Copyright © 2016 Elsevier B.V. All rights reserved.

Background Early language delay is a high-prevalence condition of concern to parents and professionals. It may result in lifelong deficits not only in language function, but also in social, emotional/behavioural, academic and economic well-being. Such delays can lead to considerable costs to the individual, the family and to society more widely. The Language for Learning trial tests a population-based intervention in 4 year olds with measured language delay, to determine (1) if it improves language and associated outcomes at ages 5 and 6 years and (2) its cost-effectiveness for families and the health care system. Methods/Design A large-scale randomised trial of a year-long intervention targeting preschoolers with language delay, nested within a well-documented, prospective, population-based cohort of 1464 children in Melbourne, Australia. All children received a 1.25-1.5 hour formal language assessment at their 4th birthday. The 200 children with expressive and/or receptive language scores more than 1.25 standard deviations below the mean were randomised into intervention or ‘usual care’ control arms. The 20-session intervention program comprises 18 one-hour home-based therapeutic sessions in three 6-week blocks, an outcome assessment, and a final feed-back/forward planning session. The therapy utilises a ‘step up-step down’ therapeutic approach depending on the child’s language profile, severity and progress, with standardised, manualised activities covering the four language development domains of: vocabulary and grammar; narrative skills; comprehension monitoring; and phonological awareness/pre-literacy skills. Blinded follow-up assessments at ages 5 and 6 years measure the primary outcome of receptive and expressive language, and secondary outcomes of vocabulary, narrative, and phonological skills. Discussion A key strength of this robust study is the implementation of a therapeutic framework that provides a standardised yet tailored approach for each child, with a focus on specific language domains known to be associated with later language and literacy. The trial responds to identified evidence gaps, has outcomes of direct relevance to families and the community, includes a well-developed economic analysis, and has the potential to improve long-term consequences of early language delay within a public health framework.

The language development of twins tends to lag behind in comparison to that of singletons. The purpose of this study was to compare expressive and receptive language skills of 3- to 12-year-old twins with singletons. Secondly, correlations between language differences between twins and singletons and age were investigated. Twenty-four twins with a mean age of 5.1 years participated in the study. The control group consisted of 24 singletons who were matched for gender and age. Language development was investigated using the Clinical Evaluation of Language Fundamentals. Twins scored significantly lower for expressive and receptive language skills compared to singletons. Even when excluding preterm-born children, twins still scored significantly lower for expressive language skills. There was no correlation between age and language differences between twins and their matched singletons. Twins score lower for expressive and receptive language skills compared to singletons, and preterm birth cannot be regarded as the main cause for the language delay. The language delay in twins is rather mild but does not seem to decrease with increasing age. © 2016 S. Karger AG, Basel.

One potential source of heterogeneity within autism spectrum conditions (ASC) is language development and ability. In 80 high-functioning male adults with ASC, we tested if variations in developmental and current structural language are associated with current neuroanatomy. Groups with and without language delay differed behaviorally in early social reciprocity, current language, but not current autistic features. Language delay was associated with larger total gray matter (GM) volume, smaller relative volume at bilateral insula, ventral basal ganglia, and right superior, middle, and polar temporal structures, and larger relative volume at pons and medulla oblongata in adulthood. Despite this heterogeneity, those with and without language delay showed significant commonality in morphometric features when contrasted with matched neurotypical individuals (n = 57). In ASC, better current language was associated with increased GM volume in bilateral temporal pole, superior temporal regions, dorsolateral fronto-parietal and cerebellar structures, and increased white matter volume in distributed frontal and insular regions. Furthermore, current language–neuroanatomy correlation patterns were similar across subgroups with or without language delay. High-functioning adult males with ASC show neuroanatomical variations associated with both developmental and current language characteristics. This underscores the importance of including both developmental and current language as specifiers for ASC, to help clarify heterogeneity. PMID:25249409

Beyond pragmatics: morphosyntactic development in autism.
Eigsti, Inge-Marie; Bennetto, Loisa; Dadlani, Mamta B
2007-07-01
Language acquisition research in autism has traditionally focused on high-level pragmatic deficits. Few studies have examined grammatical abilities in autism, with mixed findings. The present study addresses this gap in the literature by providing a detailed investigation of syntactic and higher-level discourse abilities in verbal children with autism, age 5 years. Findings indicate clear language difficulties that go beyond what would be expected based on developmental level; specifically, syntactic delays, impairments in discourse management and increased production of non-meaningful words (jargon). The present study indicates a highly specific pattern of language impairments, and importantly, syntactic delays, in a group of children with autism carefully matched on lexical level and non-verbal mental age with children with developmental delays and typical development.

Self-regulation has been found to be an important contributor to a range of outcomes, with delay of gratification (a self-regulatory skill) predicting better academic, social and personal functioning. There is some evidence that individuals with Down syndrome have difficulty with delay of gratification. We investigated the question of whether this difficulty is common to intellectual disability irrespective of aetiology, or whether it presents a particular problem for those with Down syndrome. The latter was considered a possibility because of language difficulties in this group. Three groups of children with a mean MA between 36 and 60 months participated in the study: children with Down syndrome (n = 32), children with a moderate intellectual disability from a cause other than Down syndrome (n = 26) and typically developing children (n = 50). Children completed a series of measures of language and cognitive functioning and participated in a delay of gratification task. The group of children with Down syndrome delayed for a significantly shorter time than either of the other two groups that did not differ from each other. Receptive language was associated with delay time for the children with Down syndrome but not for the typically developing group, nor for the group with moderate intellectual disability. Children with Down syndrome appear to have a particular difficulty with delay of gratification. Language abilities would seem to be implicated in this difficulty, although further examination of this hypothesis is required. © 2016 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

To investigate the usefulness of MacArthur-Bates Communicative Development Inventories-Korean (M-B CDI-K) short form as a screening test in children with language developmental delay. From April 2010 to May 2012, a total of 87 patients visited the department of physical medicine and rehabilitation of National Health Insurance Service Ilsan Hospital with the complaint of language developmental delay and were enrolled in this study. All patients took M-B CDI-K short form and Sequenced Language Scale for Infants (SELSI) or Preschool Receptive-Expressive Language Scale (PRES) according to their age. The study group consisted of 58 male patients and 29 female patients and the mean age was 25.9 months. The diagnosis are global developmental delay in 26 patients, selective language impairment in 31 patients, articulation disorder in 7 patients, cerebral palsy in 8 patients, autism spectrum disorder in 4 patients, motor developmental delay in 4 patients, and others in 7 patients. Seventy-one patients are diagnosed with language developmental delay in SELSI or PRES and of them showed 69 patients a high risk in the M-B CDI-K short form. Sixteen patients are normal in SELSI or PRES and of them showed 14 patients non-high risk in the M-B CDI-K short form. The M-B CDI-K short form has 97.2% sensitivity, 87.5% specificity, a positive predictive value of 0.97, and a negative predictive value of 0.88. The M-B CDI-K short form has a high sensitivity and specificity so it is considered as an useful screening tool in children with language developmental delay. Additional researches targeting normal children will be continued to supply the specificity of the M-B CDI-K short form.

To assess the effect of systematic clinic and home based early language intervention program in children reporting to the early language intervention clinic with full partnership of specially trained developmental therapist and the parents. All babies between 0 and 3 y referred to Child Development Centre (CDC) Kerala for suspected speech/language delay were assessed and those without hearing impairment were screened first using Language Evaluation Scale Trivandrum (LEST) and assessed in detail using Receptive Expressive Emergent Language Scale (REELS). Those having language delay are enrolled into the early language intervention program for a period of 6 mo, 1 h at the CDC clinic once every month followed by home stimulation for rest of the month by the mother trained at CDC. Out of the total 455 children between 0 and 3 y, who successfully completed 6 mo intervention, the mean pre and post intervention language quotient (LQ) were 60.79 and 70.62 respectively and the observed 9.83 increase was statistically significant. The developmental diagnosis included developmental delay (62.4%), global developmental delay (18.5%), Trisomy and other chromosomal abnormalities (10.5%), microcephaly and other brain problems (9.9%), misarticulation (8.4%), autistic features (5.3%) and cleft palate and lip (3.3%) in the descending order. In the present study among 455 children between 0 and 3 y without hearing impairment, who successfully completed 6 mo early language intervention, the mean pre and post intervention LQ were 60.79 and 70.62 respectively and the observed 9.83 increase was statistically significant.

Objectives This study investigated automatic assessment of vocal development in children with hearing loss as compared with children who are typically developing, have language delays, and autism spectrum disorder. Statistical models are examined for performance in a classification model and to predict age within the four groups of children. Design The vocal analysis system analyzed over 1900 whole-day, naturalistic acoustic recordings from 273 toddlers and preschoolers comprising children who were typically developing, hard of hearing, language delayed, or autistic. Results Samples from children who were hard-of-hearing patterned more similarly to those of typically-developing children than to the language-delayed or autistic samples. The statistical models were able to classify children from the four groups examined and estimate developmental age based on automated vocal analysis. Conclusions This work shows a broad similarity between children with hearing loss and typically developing children, although children with hearing loss show some delay in their production of speech. Automatic acoustic analysis can now be used to quantitatively compare vocal development in children with and without speech-related disorders. The work may serve to better distinguish among various developmental disorders and ultimately contribute to improved intervention. PMID:25587667

According to the World Health Organization, >200 million children in low- and middle-income countries experience developmental delays. However, household structure and parenting practices have been minimally explored as potential correlates of developmental delay in low- and middle-income countries, despite potential as areas for intervention. The objective of the study was to examine associations of developmental delays with use of World Health Organization-recommended parenting practices among a clinic-based cohort of children aged 6-60 months attending in La Romana, Dominican Republic. This study was conducted among 74 caregiver-child pairs attending the growth-monitoring clinic at Hospital Francisco Gonzalvo in June 2015. The Malawi Developmental Assessment Tool was adapted and performed on each child to assess socioadaptive, fine motor, gross motor, and language development. The IMCI Household Level Survey Questionnaire was used to assess parenting practices. Fisher's exact test was used to determine associations significant at P < .05. Significant variables were then entered into a multivariable logistic regression. Almost two-thirds of children had a delay in at least 1 developmental domain. Most caregivers used scolding (43.2%) or spanking (44%) for child discipline. Children who were disciplined by spanking and scolding were more likely to have language delay (P = .007) and socioadaptive delay (P = .077), respectively. On regression analysis, children with younger primary caregivers had 7 times higher odds of language delay (adjusted odds ratio [AOR]: 7.35, 95% confidence interval [CI]: 1.52-35.61) and 4 times greater odds of any delay (AOR: 4.72, 95% CI: 1.01-22.22). In addition, children punished by spanking had 5 times higher odds of having language delay (AOR: 5.04, 95% CI: 1.13-22.39). Parenting practices such as harsh punishment and lack of positive parental reinforcement were found to have strong associations with language and socioadaptive delays. Likewise, delays were also more common among children with younger caregivers. Copyright © 2017 Icahn School of Medicine at Mount Sinai. Published by Elsevier Inc. All rights reserved.

Fine motor skill predicts expressive language in infant siblings of children with autism.
LeBarton, Eve Sauer; Iverson, Jana M
2013-11-01
We investigated whether fine motor and expressive language skills are related in the later-born siblings of children with autism (heightened-risk, HR infants) who are at increased risk for language delays. We observed 34 HR infants longitudinally from 12 to 36 months. We used parent report and standardized observation measures to assess fine motor skill from 12 to 24 months in HR infants (Study 1) and its relation to later expressive vocabulary at 36 months in HR infants (Study 2). In Study 1, we also included 25 infants without a family history of autism to serve as a normative comparison group for a parent-report fine motor measure. We found that HR infants exhibited fine motor delays between 12 and 24 months and expressive vocabulary delays at 36 months. Further, fine motor skill significantly predicted expressive language at 36 months. Fine motor and expressive language skills are related early in development in HR infants, who, as a group, exhibit risk for delays in both. Our findings highlight the importance of considering fine motor skill in children at risk for language impairments and may have implications for early identification of expressive language difficulties. © 2013 John Wiley & Sons Ltd.

It was hypothesized that prenatal exposure to cocaine and other substances would be related to delayed expressive language development. Speech and language data were available for 458 6-year olds (204 were exposed to cocaine). No significant univariate or multivariate differences by cocaine exposure group were observed. Classification and regression tree modeling was then used to identify language variable composites predictive of cocaine exposure status. Meaningful cut points for two language measures were identified and validated. Children with a type token ratio of less than 0.42 and with fewer than 97 word types were classified into a low language group. Low language children (n = 57) were more likely to be cocaine exposed (63.1%), with cocaine-exposed children 2.4 times more likely to be in the low language group compared with control children after adjustment for covariates. Prenatal cigarette, but not alcohol exposure, was also significantly related to expressive language delays.

The current research sought to determine (a) if speech inconsistency is a core feature of childhood apraxia of speech (CAS) or if it is driven by comorbid language impairment that affects a large subset of children with CAS and (b) if speech inconsistency is a sensitive and specific diagnostic marker that can differentiate between CAS and speech delay. Participants included 48 children ranging between 4;7 to 17;8 (years;months) with CAS (n = 10), CAS + language impairment (n = 10), speech delay (n = 10), language impairment (n = 9), or typical development (n = 9). Speech inconsistency was assessed at phonemic and token-to-token levels using a variety of stimuli. Children with CAS and CAS + language impairment performed equivalently on all inconsistency assessments. Children with language impairment evidenced high levels of speech inconsistency on the phrase "buy Bobby a puppy." Token-to-token inconsistency of monosyllabic words and the phrase "buy Bobby a puppy" was sensitive and specific in differentiating children with CAS and speech delay, whereas inconsistency calculated on other stimuli (e.g., multisyllabic words) was less efficacious in differentiating between these disorders. Speech inconsistency is a core feature of CAS and is efficacious in differentiating between children with CAS and speech delay; however, sensitivity and specificity are stimuli dependent.

Development and characteristics of children with Usher syndrome and CHARGE syndrome.
Dammeyer, Jesper
2012-09-01
Individuals with Usher syndrome or CHARGE syndrome are faced with a number of difficulties concerning hearing, vision, balance, and language development. The aim of the study is to describe the developmental characteristics of children with Usher syndrome and CHARGE syndrome, respectively. Data about the developmental characteristics of 26 children with Usher syndrome and 17 children with CHARGE syndrome was obtained. Associations between deafblindness (dual sensory loss), motor development (age of walking), language abilities, and intellectual outcome of these children were explored for each group independently. Both groups of children face a number of difficulties associated with vision, hearing, language, balance and intellectual outcome. Intellectual disability and/or language delay was found among 42% of the children with Usher syndrome and among 82% of the children with CHARGE syndrome. Intellectual disability was associated with language delay and age of walking for both groups. Even though Usher and CHARGE are two different genetic syndromes, both groups are challenged with a number of similar developmental delays. Clinicians need to be aware of several developmental issues in order to offer adequate support to children with Usher or CHARGE syndrome. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Purpose The purpose of the present investigation is to differentiate children using cochlear implants (CIs) who did or did not achieve age-appropriate language scores by midelementary grades and to identify risk factors for persistent language delay following early cochlear implantation. Materials and Method Children receiving unilateral CIs at young ages (12–38 months) were tested longitudinally and classified with normal language emergence (n = 19), late language emergence (n = 22), or persistent language delay (n = 19) on the basis of their test scores at 4.5 and 10.5 years of age. Relative effects of demographic, audiological, linguistic, and academic characteristics on language emergence were determined. Results Age at CI was associated with normal language emergence but did not differentiate late emergence from persistent delay. Children with persistent delay were more likely to use left-ear implants and older speech processor technology. They experienced higher aided thresholds and lower speech perception scores. Persistent delay was foreshadowed by low morphosyntactic and phonological diversity in preschool. Logistic regression analysis predicted normal language emergence with 84% accuracy and persistent language delay with 74% accuracy. Conclusion CI characteristics had a strong effect on persistent versus resolving language delay, suggesting that right-ear (or bilateral) devices, technology upgrades, and improved audibility may positively influence long-term language outcomes.

The study aims to describe receptive language skills in children with intellectual disability (ID) and to contribute to the debate on deviant versus delayed language development. This is the 1st study of receptive skills in children with ID who speak a Slavic language, providing insight into how language development is affected by disability and also language typology. Twenty-eight Slovak-speaking children participated in the study (14 children with ID and 14 typically developing [TD] children matched on nonverbal reasoning abilities). The children were assessed by receptive language tasks targeting words, sentences, and stories, and the groups were compared quantitatively and qualitatively. The groups showed similar language profiles, with a better understanding of words, followed by sentences, with the poorest comprehension for stories. Nouns were comprehended better than verbs; sentence constructions also showed a qualitatively similar picture, although some dissimilarities emerged. Verb comprehension was strongly related to sentence comprehension in both groups and related to story comprehension in the TD group only. The findings appear to support the view that receptive language skills follow the same developmental route in children with ID as seen in younger TD children, suggesting that language development is a robust process and does not seem to be differentially affected by ID even when delayed.

Objective Studies of language development in children with mild-moderate hearing loss are relatively rare. Longitudinal studies of children with late-identified hearing loss have not been conducted, and they are relevant for determining how a period of unaided mild-moderate hearing loss impacts development. In recent years, newborn hearing screening programs have effectively reduced the ages of identification for most children with permanent hearing loss. However, some children continue to be identified late and research is needed to guide management decisions. Further, studies of this group may help to discern if language normalizes following intervention, and/or if certain aspects of language might be vulnerable to persistent delays. The current study examines the impact of late identification and reduced audibility on speech and language outcomes via a longitudinal study of four children with mild-moderate sensorineural hearing loss. Design Longitudinal outcomes of four children with late-identified mild-moderate sensorinueral hearing loss were studied using standardized measures and language sampling procedures, from at or near the point of identification (28 – 41 months) through 84 months of age. The children with hearing loss were compared to ten age-matched children with normal hearing on a majority of the measures through 60 months of age. Spontaneous language samples were collected from mother-child interaction sessions, recorded at consistent intervals in a laboratory-based play setting. Transcripts were analyzed using computer-based procedures (Systematic Analysis of Language Transcripts) and the Index of Productive Syntax. Possible influences of audibility were explored by examining the onset and productive use of a set of verb tense markers, and by monitoring the children’s accuracy in use of morphological endings. Phonological samples at baseline were transcribed and analyzed using Computerized Profiling. Results At entry to the study, the four children with hearing loss demonstrated language delays, with pronounced delays in phonological development. Three of the four children demonstrated rapid progress with development and interventions, and performed within the average range on standardized speech and language measures compared to age-matched children by 60-months of age. However, persistent differences from children with normal hearing were observed in the areas of morphosyntax, speech intelligibility in conversation, and production of fricatives. Children with mild-moderate hearing loss demonstrated later than typical emergence of certain verb tense markers, which may be related to reduced or inconsistent audibility. Conclusions The results of this study suggest that early communication delays will resolve for children with late-identified mild-moderate hearing loss, given appropriate amplification and intervention services. A positive result is that three of four children demonstrated normalization of broad language behaviors by 60-months of age, in spite of significant delays at baseline. However, these children are at risk for persistent delays in phonology at the conversational level and for accuracy in use of morphological markers. The ways in which reduced auditory experiences and audibility may contribute to these delays are explored, along with implications for evaluation of outcomes. PMID:20548239

2017-11-09
This longitudinal study compared the development of hand and index-finger pointing in children with typical language development (TD) and children with language delay (LD). First, we examined whether the number and the form of pointing gestures during the second year of life are potential indicators of later LD. Second, we analyzed the influence of caregivers' gestural and verbal input on children's communicative development. Thirty children with TD and 10 children with LD were observed together with their primary caregivers in a seminatural setting in 5 sessions between the ages of 12 and 21 months. Language skills were assessed at 24 months. Compared with children with TD, children with LD used fewer index-finger points at 12 and 14 months but more pointing gestures in total at 21 months. There were no significant differences in verbal or gestural input between caregivers of children with or without LD. Using more index-finger points at the beginning of the second year of life is associated with TD, whereas using more pointing gestures at the end of the second year of life is associated with delayed acquisition. Neither the verbal nor gestural input of caregivers accounted for differences in children's skills.

This longitudinal study compared the development of oral language and more specifically narrative skills (storytelling and story retelling) in children with specific language impairment (SLI) with and without literacy delay. Therefore, 18 children with SLI and 18 matched controls with normal literacy were followed from the last year of kindergarten (mean age=5 years 5 months) until the beginning of grade 3 (mean age=8 years 1 month). Oral language tests measuring vocabulary, morphology, sentence and text comprehension and narrative skills were administered yearly. Based on first and third grade reading and spelling achievement, both groups were divided into a group with and a group without literacy problems. Results showed that the children with SLI and literacy delay had persistent oral language problems across all assessed language domains. The children with SLI and normal literacy skills scored also persistently low on vocabulary, morphology and story retelling skills. Only on listening comprehension and storytelling, they evolved towards the level of the control group. In conclusion, oral language skills in children with SLI and normal literacy skills remained in general poor, despite their intact literacy development during the first years of literacy instruction. Only for listening comprehension and storytelling, they improved, probably as a result of more print exposure. Copyright © 2012 Elsevier Ltd. All rights reserved.

A long-standing belief is that sign language interferes with spoken language development in deaf children, despite a chronic lack of evidence supporting this belief. This deserves discussion as poor life outcomes continue to be seen in the deaf population. This commentary synthesizes research outcomes with signing and non-signing children and highlights fully accessible language as a protective factor for healthy development. Brain changes associated with language deprivation may be misrepresented as sign language interfering with spoken language outcomes of cochlear implants. This may lead to professionals and organizations advocating for preventing sign language exposure before implantation and spreading misinformation. The existence of one-time-sensitive-language acquisition window means a strong possibility of permanent brain changes when spoken language is not fully accessible to the deaf child and sign language exposure is delayed, as is often standard practice. There is no empirical evidence for the harm of sign language exposure but there is some evidence for its benefits, and there is growing evidence that lack of language access has negative implications. This includes cognitive delays, mental health difficulties, lower quality of life, higher trauma, and limited health literacy. Claims of cochlear implant- and spoken language-only approaches being more effective than sign language-inclusive approaches are not empirically supported. Cochlear implants are an unreliable standalone first-language intervention for deaf children. Priorities of deaf child development should focus on healthy growth of all developmental domains through a fully-accessible first language foundation such as sign language, rather than auditory deprivation and speech skills.

Research suggests that a sub-set of children with autism experience notable difficulties and delays in motor skills development, and that a large percentage of children with autism experience deficits in motor resonance. These motor-related deficiencies, which evidence suggests are present from a very early age, are likely to negatively affect social-communicative and language development in this population. Here, we review evidence for delayed, impaired, and atypical motor development in infants and children with autism. We then carefully review and examine the current language and communication-based intervention research that is relevant to motor and motor resonance (i.e., neural “mirroring” mechanisms activated when we observe the actions of others) deficits in children with autism. Finally, we describe research needs and future directions and developments for early interventions aimed at addressing the speech/language and social-communication development difficulties in autism from a motor-related perspective.

This study aimed to understand if maternal interpersonal violence-related posttraumatic stress disorder (IPV-PTSD) is associated with delayed language development among very young children ("toddlers"). Data were collected from 61 mothers and toddlers (ages 12-42 months, mean age = 25.6 months SD = 8.70). Child expressive and receptive language development was assessed by the Ages and Stages Questionnaire (ASQ) communication subscale (ASQCS) that measures language acquisition. Observed maternal caregiving behavior was coded from videos of 10-min free-play interactions via the CARE-Index. Correlations, Mann-Whitney tests, and multiple linear regression were performed. There was no significant association between maternal IPV-PTSD severity and the ASQCS. Maternal IPV-PTSD severity was associated with continuous maternal behavior variables (i.e. sensitive and controlling behavior on the CARE-Index) across the entire sample and regardless of child gender. Maternal sensitivity was positively and significantly associated with the ASQCS. Controlling behavior was negatively and significantly associated with the ASQCS. Results are consistent with the literature that while maternal IPV-PTSD severity is not associated with child language delays, the quality of maternal interactive behavior is associated both with child language development and with maternal IPV-PTSD severity. Further study is needed to understand if the level of child language development contributes to intergenerational risk or resilience for relational violence and/or victimization.

Otolaryngologists are asked to evaluate children who a parent, physician, or someone else believes is slow in developing speech. Therefore, an otolaryngologist should be familiar with milestones for normal speech development, the causes of delay in speech development, and the best ways to help assure that children develop the ability to speak in a normal way. To provide information for otolaryngologists that is helpful in the evaluation and management of children perceived to be delayed in developing speech. Data were obtained via literature searches, online databases, textbooks, and the most recent national guidelines on topics including speech delay and language delay and the underlying disorders that can cause delay in developing speech. Emphasis was placed on epidemiology, pathophysiology, most common presentation, and treatment strategies. Most of the sources referenced were published within the past 5 years. Our article is a summary of major causes of speech delay based on reliable sources as listed herein. Speech delay can be the manifestation of a spectrum of disorders affecting the language comprehension and/or speech production pathways, ranging from disorders involving global developmental limitations to motor dysfunction to hearing loss. Determining the cause of a child's delay in speech production is a time-sensitive issue because a child loses valuable opportunities in intellectual development if his or her communication defect is not addressed and ameliorated with treatment. Knowing several key items about each disorder can help otolaryngologists direct families to the correct health care provider to maximize the child's learning potential and intellectual growth curve.

The incidence of language delay in Chinese preschool children was studied by a stratified proportional sampling of all 3 year olds in Hong Kong. The Developmental Language Screening Scale (DLSS) devised for use with Cantonese speaking children was used to identify children with language delay. Of 855 children sampled in the stage I screening procedure, 4%, 2.8% and 3.3% were identified as having delay in verbal comprehension, expression or both respectively. The stage II clinical diagnostic study included a randomly selected group of children screened in stage I with or without any associated behavioural problem. Among these, 3.4% were identified as having a language delay using the Reynell Language Developmental Scale (RDLS) with a criterion of language age of less than or equal to two-thirds of the chronological age; 3% had specific language delay using the criteria of language age less than or equal to two-thirds the chronological age and developmental age more than or equal to two-thirds the chronological age. More boys were found to have language delay, although this was not statistically significant.

Autism spectrum disorders (ASD) are a group of conditions that show abnormalities in the neuroanatomy of multiple brain regions. The variability in the development of intelligence and language among individuals on the autism spectrum has long been acknowledged, but it remains unknown whether these differences impact on the neuropathology of ASD. In this study, we aimed to compare associations between surface-based regional brain measures and general intelligence (IQ) scores in ASD individuals with and without a history of language delay. We included 64 ASD adults of normal intelligence (37 without a history of language delay and 27 with a history of language delay and 80 neurotypicals). Regions with a significant association between verbal and nonverbal IQ and measures of cortical thickness (CT), surface area, and cortical volume were first identified in the combined sample of individuals with ASD and controls. Thicker dorsal frontal and temporal cortices, and thinner lateral orbital frontal and parieto-occipital cortices were associated with greater and lower verbal IQ scores, respectively. Correlations between cortical volume and verbal IQ were observed in similar regions as revealed by the CT analysis. A significant difference between ASD individuals with and without a history of language delay in the association between CT and verbal IQ was evident in the parieto-occipital region. These results indicate that ASD subgroups defined on the basis of differential language trajectories in childhood can have different associations between verbal IQ and brain measures in adulthood despite achieving similar levels of cognitive performance. © 2015 International Society for Autism Research, Wiley Periodicals, Inc.

The aim of the study was to examine the relationship between social withdrawal behaviour at one year and motor and language milestones. One-year old children from the EDEN French population-based birth cohort study (Study on the pre- and postnatal determinants of the child's development and prospective health Birth Cohort Study) were included. Social withdrawal at one year was assessed by trained midwives using the Alarm Distress BaBy (ADBB) scale. Midwives concurrently examined infants' motor and language milestones. Parents reported on child's psychomotor and language milestones, during the interview with the midwife. After adjusting for potential confounding factors, social withdrawal behaviour was significantly associated with concurrent delays in motor and language milestones assessed by the midwife or the parents. Higher scores on social withdrawal behaviour as assessed with the ADBB were associated with delays in reaching language milestones, and to a lesser extent with lower motor ability scores. Taking the contribution of social withdrawal behaviour into account may help understand the unfolding of developmental difficulties in children.

Management of developmental speech and language disorders: Part 1.
O'Hare, Anne; Bremner, Lynne
2016-03-01
The identification of developmental problems in a child's acquisition of speech, language and/or communication is a core activity in child surveillance. These are common difficulties with up to 15% of toddlers being 'late talkers' and 7% of children entering school with persisting impairments of their language development. These delays can confer disadvantages in the long term, adversely affecting language, cognition, academic attainment, behaviour and mental health. All children presenting with significant speech and language delay should be investigated with a comprehensive hearing assessment and be considered for speech and language therapy assessment. Socioeconomic adversity correlates with delayed language development. Clinical assessment should confirm that the presentation is definitely not acquired (see part 2) and will also guide whether the difficulty is primary, in which there are often familial patterns, or secondary, from a very wide range of aetiologies. Symptoms may be salient, such as the regression of communication in <3-year-olds which 'flags up' autism spectrum disorder. Further investigation will be informed from this clinical assessment, for example, genetic investigation for sex aneuploidies in enduring primary difficulties. Management of the speech and language difficulty itself is the realm of the speech and language therapist, who has an ever-increasing evidence-based choice of interventions. This should take place within a multidisciplinary team, particularly for children with more severe conditions who may benefit from individualised parental and educational supports.

The objectives were (1) to assess associations between sleep consolidation at 6, 18 and 30 months and language skills at 18, 30, and 60 months; and (2) to investigate the genetic/environmental etiology of these associations. Longitudinal study of a population-based twin cohort. 1029 twins from the Quebec Newborn Twin Study. Sleep consolidation was derived from parental reports of day/night consecutive sleeping durations. Language skills were assessed with the MacArthur Communicative Development Inventory at 18 and 30 months and the Peabody Picture Vocabulary Test at 60 months. The day/night sleep ratio decreased significantly from 6 to 30 months. The 6- and 18-month ratios were negatively correlated with subsequent language skills. Children with language delays at 60 months had less mature sleep consolidation at both 6 and 18 months than children without delays and those with transient early delays. Genetic and regression analyses revealed that the sleep ratio at 6 months was highly heritable (64%) and predicted 18-month (B = -0.06) and 30-month language (B = -0.11) mainly through additive genetic influences (R(Gs) = 0.32 and 0.33, respectively). By contrast, the sleep ratio at 18 months was mainly due to shared environment influences (58%) and predicted 60-month language (B = -0.08) through shared environment influences (R(Cs) = 0.24). Poor sleep consolidation during the first 2 years of life may be a risk factor for language learning, whereas good sleep consolidation may foster language learning through successive genetic and environmental influences.

Using time-delay to improve social play skills with peers for children with autism.
Liber, Daniella B; Frea, William D; Symon, Jennifer B G
2008-02-01
Interventions that teach social communication and play skills are crucial for the development of children with autism. The time delay procedure is effective in teaching language acquisition, social use of language, discrete behaviors, and chained activities to individuals with autism and developmental delays. In this study, three boys with autism, attending a non-public school, were taught play activities that combined a play sequence with requesting peer assistance, using a graduated time delay procedure. A multiple-baseline across subjects design demonstrated the success of this procedure to teach multiple-step social play sequences. Results indicated an additional gain of an increase in pretend play by one of the participants. Two also demonstrated a generalization of the skills learned through the time delay procedure.

Early development in males with Fragile X syndrome: a review of the literature.
Kau, Alice S M; Meyer, Walter A; Kaufmann, Walter E
2002-05-01
This article reviews the current bibliographic knowledge on early neurobehavioral development and milestones in Fragile X syndrome (FraX), with emphasis on males affected by the condition. Three broad areas of early development were examined: (1) gross and fine motor, (2) speech and language, and (3) social. The result of the current review indicates very limited information on the developmental milestones in all three areas. The scarce literature on motor development shows that in FraX there is an early developmental delay. Research on speech and language demonstrates pervasive deficits in conversational skills and severe developmental delay, with increasing discrepancy between language level and chronological age in young males with FraX. Finally, deficits in social development in FraX include abnormal gaze, approach and avoidance conflict, and high incidence of autistic spectrum disorders. Copyright 2002 Wiley-Liss, Inc.

This study investigates whether distinct neurodevelopmental disorders show distinct patterns of impairments in particular grammatical abilities and the relation of those grammatical patterns to general language delays and intellectual disabilities. We studied two disorders (autism and Williams syndrome [WS]) and two distinct properties (Principle A that governs reflexives and Principle B that, together with its associated pragmatic rule, governs pronouns) of the binding module of grammar. These properties are known to have markedly different courses of acquisition in typical development. We compare the knowledge of binding in children with autism with language impairment (ALI) and those with normal language (ALN) to that of children with WS, matched on age to the ALN group, and on age and nonverbal mental age (MA) to the ALI group, as well as to two groups of typically developing (TD) controls, matched on nonverbal MA to ALI and ALN groups. Our results reveal a remarkably different pattern of comprehension of personal pronouns and reflexives in ALI as opposed to ALN, WS, and two groups of TD controls. All five groups demonstrated an equal delay in their comprehension of personal pronouns, in line with widely reported delays in TD literature, argued to be due to delayed pragmatic abilities. However, and most strikingly, the ALI group also showed a pronounced difficulty in comprehension of reflexive pronouns, and particularly of the knowledge that the antecedent of a reflexive must c-command it. The revealed pattern confirms the existence of a particular impairment concerning Principle A in this module of grammar, unrelated to general language delays or cognitive deficits generally present in a large portion of individuals with autism as well as WS, or to general pragmatic deficits, known to be particularly prevalent in the population with autism.

The phenotype of partial trisomy 9p includes global developmental delay, microcephaly, bulbous nose, downturned oral commissures, malformed ears, hypotonia, and severe cognitive and language disorders. We present a case report and a comparative review of clinical findings on this condition, focusing on speech-language development, cognitive abilities and swallowing evaluation. We suggest that oropharyngeal dysphagia should be further investigated, considering that pulmonary and nutritional disorders affect the survival and quality of life of the patient. As far as we know, this is the first study of a patient with partial trisomy 9p described with oropharyngeal dysphagia.

Early language development in Indian children: A population-based pilot study
Sidhu, Manjit; Malhi, Prahbhjot; Jerath, Jagat
2013-01-01
Objectives: To study the prevalence of language delay and to examine its socio-economic correlates in children less than 3 years. Materials and Methods: Participants were 130 children (males = 56%) aged 12-35 months (mean age = 1.81 years, SD = 0.58), from an urban center in north India. The language quotient (LQ) of the child was measured by the Clinical Linguistic Auditory Milestone Scale (CLAMS). Children with an LQ score of less than 70 were considered language delayed. Results: Overall, 6.2% of the children were language delayed with a higher prevalence found for girls (7%) than for boys (5.5%), although the difference was not statistically significant. Several significant correlations between socio-economic and demographic variables and the LQ of the child were found. Stepwise multiple regression analysis revealed that 31.4% of the variance in the LQ scores of girls was accounted for by income (F = 23.80, P = 0.000) and 18.1% of the variance in the LQ scores of boys was accounted for by education of the mother and income (F = 15.67, P = 0.000). Conclusions: Developmental problems in early years are often precursors of problems in later life and early intervention can facilitate favorable outcomes among children with multiple risks. The high prevalence of language difficulties in young children underscores the need to target language delay in early years, to reduce the likelihood of adverse outcomes and thus optimize chances of improvement.

2013-01-01
Objective We examined early speech and language development in children who had cerebral palsy. Questions addressed whether children could be classified into early profile groups on the basis of speech and language skills and whether there were differences on selected speech and language measures among groups. Methods Speech and language assessments were completed on 27 children with CP who were between the ages of 24-30 months (mean age 27.1 months; SD 1.8). We examined several measures of expressive and receptive language, along with speech intelligibility. Results 2-step cluster analysis was used to identify homogeneous groups of children based on their performance on the 7 dependent variables characterizing speech and language performance. Three groups of children identified were those not yet talking (44% of the sample); those whose talking abilities appeared to be emerging (41% of the sample); and those who were established talkers (15% of the sample). Group differences were evident on all variables except receptive language skills. Conclusion 85% of 2 year old children with CP in this study had clinical speech and /or language delays relative to age expectations. Findings suggest that children with CP should receive speech and language assessment and treatment to identify and treat those with delays at or before 2 years of age. PMID:23627373

Language Promotes False-Belief Understanding
Pyers, Jennie E.; Senghas, Ann
2010-01-01
Developmental studies have identified a strong correlation in the timing of language development and false-belief understanding. However, the nature of this relationship remains unresolved. Does language promote false-belief understanding, or does it merely facilitate development that could occur independently, albeit on a delayed timescale? We examined language development and false-belief understanding in deaf learners of an emerging sign language in Nicaragua. The use of mental-state vocabulary and performance on a low-verbal false-belief task were assessed, over 2 years, in adult and adolescent users of Nicaraguan Sign Language. Results show that those adults who acquired a nascent form of the language during childhood produce few mental-state signs and fail to exhibit false-belief understanding. Furthermore, those whose language developed over the period of the study correspondingly developed in false-belief understanding. Thus, language learning, over and above social experience, drives the development of a mature theory of mind. PMID:19515119

This study examined longitudinal associations between specific parenting factors and delay inhibition in socioeconomically disadvantaged preschoolers. At Time 1, parents and 2- to 4-year-old children (mean age = 3.21 years; N = 247) participated in a videotaped parent-child free play session, and children completed delay inhibition tasks (gift delay-wrap, gift delay-bow, and snack delay tasks). Three months later, at Time 2, children completed the same set of tasks. Parental responsiveness was coded from the parent-child free play sessions, and parental directive language was coded from transcripts of a subset of 127 of these sessions. Structural equation modeling was used, and covariates included age, gender, language skills, parental education, and Time 1 delay inhibition. Results indicated that in separate models, Time 1 parental directive language was significantly negatively associated with Time 2 delay inhibition, and Time 1 parental responsiveness was significantly positively associated with Time 2 delay inhibition. When these parenting factors were entered simultaneously, Time 1 parental directive language significantly predicted Time 2 delay inhibition whereas Time 1 parental responsiveness was no longer significant. Findings suggest that parental language that modulates the amount of autonomy allotted the child may be an important predictor of early delay inhibition skills. PMID:27833461

Which are the best predictors of theory of mind delay in children with specific language impairment?
Andrés-Roqueta, Clara; Adrian, Juan E; Clemente, Rosa A; Katsos, Napoleon
2013-01-01
The relationship between language and theory of mind (ToM) development in participants with specific language impairment (SLI) it is far from clear due to there were differences in study design and methodologies of previous studies. This research consisted of an in-depth investigation of ToM delay in children with SLI during the typical period of acquisition, and it studied whether linguistic or information-processing variables were the best predictors of this process. It also took into account whether there were differences in ToM competence due to the degree of pragmatic impairment within the SLI group. Thirty-one children with SLI (3;5-7;5 years old) and two control groups (age matched and language matched) were assessed with False Belief (FB) tasks, a wide battery of language measures and additional information-processing measures. The members of the SLI group were less competent than their age-matched peers at solving FB tasks, but they performed similarly to the language-matched group. Regression analysis showed that overall linguistic skills of children with SLI were the best predictor of ToM performance, and especially grammar abilities. No differences between SLI subgroups were found according to their pragmatic level. A delay in ToM development in children with SLI around the critical period of acquisition is confirmed more comprehensively, and it is shown to be more strongly related to their general linguistic level than to their age and other information-processing faculties. This finding stresses the importance of early educational and clinical programmes aimed at reducing deleterious effects in later development. © 2013 Royal College of Speech and Language Therapists.

Language Disorders: A 10-Year Research Update Review
TOPPELBERG, CLAUDIO O.; SHAPIRO, THEODORE
2012-01-01
Objective To review the past 10 years of research in child language or communication disorders, which are highly prevalent in the general population and comorbid with childhood psychiatric disorders. Method A literature search of 3 major databases was conducted. The child language literature, describing the domains of language development—phonology, grammar, semantics, and pragmatics—is reviewed. Results Disorders of grammar, semantics, and pragmatics, but not phonology, overlap significantly with childhood psychiatric disorders. Receptive language disorders have emerged as high-risk indicators, often undiagnosed. Language disorders and delays are psychiatric risk factors and have implications for evaluation, therapy, and research. However, they are often undiagnosed in child mental health and community settings. The research has focused mostly on monolingual English-speaking children. Conclusion Awareness of basic child language development, delay, and deviance is crucial for the practicing child and adolescent psychiatrist, who must diagnose and refer relevant cases for treatment and remediation. Future research needs to address the growing language diversity of our clinical populations. PMID:10673823

Objective The aim of the study was to examine the relationship between social withdrawal behaviour at one year and motor and language milestones. Materials and Methods One-year old children from the EDEN French population-based birth cohort study (Study on the pre- and postnatal determinants of the child’s development and prospective health Birth Cohort Study) were included. Social withdrawal at one year was assessed by trained midwives using the Alarm Distress BaBy (ADBB) scale. Midwives concurrently examined infants’ motor and language milestones. Parents reported on child’s psychomotor and language milestones, during the interview with the midwife. Results After adjusting for potential confounding factors, social withdrawal behaviour was significantly associated with concurrent delays in motor and language milestones assessed by the midwife or the parents. Discussion Higher scores on social withdrawal behaviour as assessed with the ADBB were associated with delays in reaching language milestones, and to a lesser extent with lower motor ability scores. Taking the contribution of social withdrawal behaviour into account may help understand the unfolding of developmental difficulties in children. PMID:27391482

Because nervous system development may be affected by prematurity, many prematurely born children present language or cognitive disorders at school age. The goal of this study is to investigate whether these impairments can be identified early in life using electrophysiological auditory event-related potentials (AERPs) and mismatch negativity (MMN). Brain responses to speech and non-speech stimuli were assessed in prematurely born children to identify early electrophysiological markers of language and cognitive impairments. Participants were 74 children (41 full-term, 33 preterm) aged 3, 12, and 36 months. Pre-attentional auditory responses (MMN and AERPs) were assessed using an oddball paradigm, with speech and non-speech stimuli presented in counterbalanced order between participants. Language and cognitive development were assessed using the Bayley Scale of Infant Development, Third Edition (BSID-III). Results show that preterms as young as 3 months old had delayed MMN response to speech stimuli compared to full-terms. A significant negative correlation was also found between MMN latency to speech sounds and the BSID-III expressive language subscale. However, no significant differences between full-terms and preterms were found for the MMN to non-speech stimuli, suggesting preserved pre-attentional auditory discrimination abilities in these children. Identification of early electrophysiological markers for delayed language development could facilitate timely interventions. Copyright © 2015 Elsevier Ltd. All rights reserved.

The facilitative effects of incidental teaching on preposition use by autistic children.
McGee, G G; Krantz, P J; McClannahan, L E
1985-01-01
In a comparison of incidental teaching and traditional training procedures, three language-delayed autistic children were taught expressive use of prepositions to describe the location of preferred edibles and toys. Traditional highly structured training and incidental teaching procedures were used in a classroom setting, and generalization was assessed during free-play sessions. Results clearly indicate that incidental teaching promoted greater generalization and more spontaneous use of prepositions. These findings have important implications for language programming and teacher training, suggesting that incidental teaching should be included as a standard component of language development curricula for autistic and other developmentally delayed children.

A growing number of studies on deaf children with cochlear implant (CI) document a significant improvement in receptive and expressive language skills after implantation, even if they show language delay when compared with normal-hearing peers. Data on language acquisition in CI Italian children are still scarce and limited to only certain aspects of language. The purpose of this study is to prospectively describe the trajectories of language development in early CI Italian children, with particular attention to the transition from first words to combinatorial speech and to acquisition of complex grammar in a language with rich morphology, such as Italian. Six children, with profound prelingual deafness, provided with CI, between 16 and 24 months of age were prospectively assessed and followed over a mean period of up to 34.8 months postimplant. During follow-up, each child received between four to five individual language evaluations through a combination of indirect procedures (parent reports of early lexical and grammar development) and direct ones (administration of standardized receptive and expressive language tests with Italian norms and collection of spontaneous language samples). In relation to chronological age, the acquisition of expressive vocabulary was delayed. However, considering the duration of hearing experience, most CI participants showed an earlier start and faster growth of expressive rather than receptive vocabulary in comparison with typically developing children. This quite atypical result persisted right up until the end of the follow-up. The acquisition of expressive grammar was delayed relative to chronological age, though all but one CI participant achieved the expected grammar level after approximately 3 years of CI use. In addition, the rate of grammar acquisition was not homogeneous during development, showing two different paces: one comparable with normal hearing in the transition from holophrastic to primitive combinatorial speech and a much slower one to attain more advanced levels of morphosyntactic control. From a rehabilitative viewpoint, our results suggest the importance of implementing rehabilitation in lexical comprehension, even when expressive vocabulary appears to be within normal range. Moreover, assessment of language acquisition in CI Italian children should focus on those grammar aspects that are more vulnerable to early acoustic deprivation (such as free and bound morphology) to ensure enhanced language therapy planning.

Latent Class Analysis of Early Developmental Trajectory in Baby Siblings of Children with Autism
Landa, Rebecca J.; Gross, Alden L.; Stuart, Elizabeth A.; Bauman, Margaret
2012-01-01
Background Siblings of children with autism (sibs-A) are at increased genetic risk for autism spectrum disorders (ASD) and milder impairments. To elucidate diversity and contour of early developmental trajectories exhibited by sibs-A, regardless of diagnostic classification, latent class modeling was used. Methods Sibs-A (n=204) were assessed with the Mullen Scales of Early Learning from age 6–36 months. Mullen T scores served as dependent variables. Outcome classifications at age 36 months included: ASD (n=52); non-ASD social/communication delay (broader autism phenotype; BAP) (n=31); and unaffected (n=121). Child-specific patterns of performance were studied using latent class growth analysis. Latent class membership was then related to diagnostic outcome through estimation of within-class proportions of children assigned to each diagnostic classification. Results A 4-class model was favored. Class 1 represented accelerated development and consisted of 25.7% of the sample, primarily unaffected children. Class 2 (40.0% of the sample), was characterized by normative development with above-average nonverbal cognitive outcome. Class 3 (22.3% of the sample) was characterized by receptive language, and gross and fine motor delay. Class 4 (12.0% of the sample), was characterized by widespread delayed skill acquisition, reflected by declining trajectories. Children with an outcome diagnosis of ASD were spread across Classes 2, 3, and 4. Conclusions Results support a category of ASD that involves slowing in early non-social development. Receptive language and motor development is vulnerable to early delay in sibs-A with and without ASD outcomes. Non-ASD sibs-A are largely distributed across classes depicting average or accelerated development. Developmental trajectories of motor, language, and cognition appear independent of communication and social delays in non-ASD sibs-A. PMID:22574686

Language development in a 3-year-old boy with Prader-Willi syndrome.
Atkin, Keith; Lorch, Marjorie Perlman
2007-04-01
Prader-Willi syndrome (PWS) is a genetic disorder which has widespread developmental consequences including motor, cognitive and language delay. Previous research on PWS children has focused primarily on phonological development and dysfluency. In the present study, the lexical development of a boy with PWS was investigated in a series of 18 play sessions recorded over a 4 month period from the ages 3;7 to 3;11. In comparison to the language development of children with Down syndrome this child with PWS appears to display a distinct developmental pattern. The possibility of detailing a behavioural phenotype of genetic disorders affecting language development is discussed.

Context Prenatal folic acid supplements reduce the risk of neural tube defects and may have beneficial effects on other aspects of neurodevelopment. Objective To examine associations between mothers' use of prenatal folic acid supplements and risk of severe language delay in their children at age 3 years. Design, Setting, and Patients The prospective observational Norwegian Mother and Child Cohort Study recruited pregnant women between 1999 and December 2008. Data on children born before 2008 whose mothers returned the 3-year follow-up questionnaire by June 16, 2010, were used. Maternal use of folic acid supplements within the interval from 4 weeks before to 8 weeks after conception was the exposure. Relative risks were approximated by estimating odds ratios (ORs) with 95% CIs in a logistic regression analysis. Main Outcome Measure Children's language competency at age 3 years measured by maternal report on a 6-point ordinal language grammar scale. Children with minimal expressive language (only 1-word or unintelligible utterances) were rated as having severe language delay. Results Among 38 954 children, 204 (0.5%) had severe language delay. Children whose mothers took no dietary supplements in the specified exposure interval were the reference group (n=9052 [24.0%], with severe language delay in 81 children [0.9%]). Adjusted ORs for 3 patterns of exposure to maternal dietary supplements were (1) other supplements, but no folic acid (n=2480 [6.6%], with severe language delay in 22 children [0.9%]; OR, 1.04; 95% CI, 0.62-1.74); (2) folic acid only (n=7127 [18.9%], with severe language delay in 28 children [0.4%]; OR, 0.55; 95% CI, 0.35-0.86); and (3) folic acid in combination with other supplements (n=19005 [50.5%], with severe language delay in 73 children [0.4%]; OR, 0.55; 95% CI, 0.39-0.78). Conclusion Among this Norwegian cohort of mothers and children, maternal use of folic acid supplements in early pregnancy was associated with a reduced risk of severe language delay in children at age 3 years.

Prenatal chemical exposures and child language development.
Dzwilewski, Kelsey L C; Schantz, Susan L
2015-01-01
The goal of this review is to summarize the evidence that prenatal and/or early postnatal exposure to certain chemicals, both manmade (insulating materials, flame retardants, pesticides) and naturally occurring (e.g., lead, mercury), may be associated with delays or impairments in language development. We focus primarily on a subset of more extensively studied chemicals-polychlorinated biphenyls (PCBs), lead, and methyl mercury-for which a reasonable body of literature on neurodevelopmental outcomes is available. We also briefly summarize the smaller body of evidence for other chemicals including polybrominated diphenyl ether flame retardants (PBDEs) and organophosphate pesticides. Very few studies have used specific assessments of language development and function. Therefore, we included discussion of aspects of cognitive development such as overall intellectual functioning and verbal abilities that rely on language, as well as aspects of cognition such as verbal and auditory working memory that are critical underpinnings of language development. A high percentage of prospective birth cohort studies of PCBs, lead, and mercury have reported exposure-related reductions in overall IQ and/or verbal IQ that persist into middle or late childhood. Given these findings, it is important that clinicians and researchers in communication sciences and disorders are aware of the potential for environmental chemicals to impact language development. The goal of this review is to summarize the evidence that prenatal and/or early postnatal exposure to certain chemicals may be associated with delays or impairments in language development. Readers will gain an understanding of the literature suggesting that early exposure to polychlorinated biphenyls (PCBs), lead, and mercury may be associated with decrements in cognitive domains that depend on language or are critical for language development. We also briefly summarize the smaller body of evidence regarding polybrominated diphenyl ether flame retardants (PBDEs) and organophosphate pesticides. Very few studies of exposure to these chemicals have used specific assessments of language development; thus, further investigation is needed before changes in clinical practice can be suggested.

In order to understand how language abilities emerge in typically and atypically developing infants and toddlers, it is important to embrace complexity in development. In this paper, we describe evidence that early language development is an experience-dependent process, shaped by diverse, interconnected, interdependent developmental mechanisms, processes, and abilities (e.g. statistical learning, sampling, functional specialization, visual attention, social interaction, motor ability). We also present evidence from our studies on neurodevelopmental disorders (e.g. Down syndrome, fragile X syndrome, Williams syndrome) that variations in these factors significantly contribute to language delay. Finally, we discuss how embracing complexity, which involves integrating data from different domains and levels of description across developmental time, may lead to a better understanding of language development and, critically, lead to more effective interventions for cases when language develops atypically.

Patterns of Adult-Child Linguistic Interaction in Integrated Day Care Groups.
Girolametto, Luigi; Hoaken, Lisa; Weitzman, Elaine; Lieshout, Riet van
2000-04-01
This study investigated the language input of eight childcare providers to children with developmental disabilities, including language delay, who were integrated into community day care centers. Structural and discourse features of the adults' language input was compared across two groups (integrated, typical) and two naturalistic day care contexts (book reading, play dough activity). The eight children with developmental disabilities and language delay were between 33-50 months of age; 32 normally developing peers ranged in age from 32-53 months of age. Adult-child interactions were transcribed and coded to yield estimates of structural indices (number of utterances, rate, mean length of utterances, ratio of different words to total words used (TTR) and discourse features (directive, interactive, language-modelling) of their language input. The language input addressed to the children with developmental disabilities was directive and not finely tuned to their expressive language levels. In turn, these children interacted infrequently with the adult or with the other children. Contextual comparisons indicated that the play dough activity promoted adult-child interaction that was less directive and more interaction-promoting than book reading, and that children interacted more frequently in the play-dough activity. Implications for speech-language pathologists include the need for collaborative consultation in integrated settings, modification of adult-child play contexts to promote interaction, and training childcare providers to use language input that promotes communication development.

Communication disorder is common in Koolen de Vries syndrome (KdVS), yet its specific symptomatology has not been examined, limiting prognostic counselling and application of targeted therapies. Here we examine the communication phenotype associated with KdVS. Twenty-nine participants (12 males, 4 with KANSL1 variants, 25 with 17q21.31 microdeletion), aged 1.0-27.0 years were assessed for oral-motor, speech, language, literacy, and social functioning. Early history included hypotonia and feeding difficulties. Speech and language development was delayed and atypical from onset of first words (2; 5-3; 5 years of age on average). Speech was characterised by apraxia (100%) and dysarthria (93%), with stuttering in some (17%). Speech therapy and multi-modal communication (e.g., sign-language) was critical in preschool. Receptive and expressive language abilities were typically commensurate (79%), both being severely affected relative to peers. Children were sociable with a desire to communicate, although some (36%) had pragmatic impairments in domains, where higher-level language was required. A common phenotype was identified, including an overriding 'double hit' of oral hypotonia and apraxia in infancy and preschool, associated with severely delayed speech development. Remarkably however, speech prognosis was positive; apraxia resolved, and although dysarthria persisted, children were intelligible by mid-to-late childhood. In contrast, language and literacy deficits persisted, and pragmatic deficits were apparent. Children with KdVS require early, intensive, speech motor and language therapy, with targeted literacy and social language interventions as developmentally appropriate. Greater understanding of the linguistic phenotype may help unravel the relevance of KANSL1 to child speech and language development.

Brain imaging methods have contributed to shed light on the possible mechanisms of recovery and cortical reorganization after early brain insult. The idea that a functional left hemisphere is crucial for achieving a normalized pattern of language development after left perinatal stroke is still under debate. We report the case of a 3.5-year-old boy born at term with a perinatal ischemic stroke of the left middle cerebral artery, affecting mainly the supramarginal gyrus, superior parietal and insular cortex extending to the precentral and postcentral gyri. Neurocognitive development was assessed at 25 and 42 months of age. Language outcomes were more extensively evaluated at the latter age with measures on receptive vocabulary, phonological whole-word production and linguistic complexity in spontaneous speech. Word learning abilities were assessed using a fast-mapping task to assess immediate and delayed recall of newly mapped words. Functional and structural imaging data as well as a measure of intrinsic connectivity were also acquired. While cognitive, motor and language levels from the Bayley Scales fell within the average range at 25 months, language scores were below at 42 months. Receptive vocabulary fell within normal limits but whole word production was delayed and the child had limited spontaneous speech. Critically, the child showed clear difficulties in both the immediate and delayed recall of the novel words, significantly differing from an age-matched control group. Neuroimaging data revealed spared classical cortical language areas but an affected left dorsal white-matter pathway together with right lateralized functional activations. In the framework of the model for Social Communication and Language Development, these data confirm the important role of the left arcuate fasciculus in understanding and producing morpho-syntactic elements in sentences beyond two word combinations and, most importantly, in learning novel word-referent associations, a building block of language acquisition.

Background Preschool language and neurodevelopmental problems often persist and impede learning. The aims of the current study are to assess the uptake of a new universal 30 month health visitor contact and to quantify the prevalence of language delay and social/emotional difficulties. Methods All families of 30 month old children in four Glasgow localities were offered a visit from their health visitor. Structured data were collected relating to language, social and emotional development using three instruments; The Strengths and Difficulties Questionnaire (SDQ), the abbreviated Sure Start Language Measure and a two-item language screen. Results From an eligible population of 543 children, there was a 90% return rate of contact forms from the health visitors, and assessments were completed on 78% of eligible children. Visit completion rates did not differ significantly by socio-economic status. 3-8% of children were reported to have language delay depending on the method of assessment. 8.8% of children scored in the “abnormal” range of SDQ total difficulties scores and 31.1% had an abnormality in at least one subscale. There was substantial overlap between language delay and abnormal scores on the SDQ. Conclusions Universal assessment of neurodevelopmental function at 30 months identified a significant proportion of children, including those previously considered at low risk, with both language and social/emotional difficulties. Further work is required to assess the precise nature of these difficulties and to assess the potential impact on services. PMID:24330767

Bayley-III Cognitive and Language Scales in Preterm Children.
Spencer-Smith, Megan M; Spittle, Alicia J; Lee, Katherine J; Doyle, Lex W; Anderson, Peter J
2015-05-01
This study aimed to assess the sensitivity and specificity of the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III), Cognitive and Language scales at 24 months for predicting cognitive impairments in preterm children at 4 years. Children born <30 weeks' gestation completed the Bayley-III at 24 months and the Differential Ability Scale, Second Edition (DAS-II), at 4 years to assess cognitive functioning. Test norms and local term-born reference data were used to classify delay on the Bayley-III Cognitive and Language scales. Impairment on the DAS-II Global Conceptual Ability, Verbal, and Nonverbal Reasoning indices was classified relative to test norms. Scores < -1 SD relative to the mean were classified as mild/moderate delay or impairment, and scores < -2 SDs were classified as moderate delay or impairment. A total of 105 children completed the Bayley-III and DAS-II. The sensitivity of mild/moderate cognitive delay on the Bayley-III for predicting impairment on DAS-II indices ranged from 29.4% to 38.5% and specificity ranged from 92.3% to 95.5%. The sensitivity of mild/moderate language delay on the Bayley-III for predicting impairment on DAS-II indices ranged from 40% to 46.7% and specificity ranged from 81.1% to 85.7%. The use of local reference data at 24 months to classify delay increased sensitivity but reduced specificity. Receiver operating curve analysis identified optimum cut-point scores for the Bayley-III that were more consistent with using local reference data than Bayley-III normative data. In our cohort of very preterm children, delay on the Bayley-III Cognitive and Language scales was not strongly predictive of future impairments. More children destined for later cognitive impairment were identified by using cut-points based on local reference data than Bayley-III norms. Copyright © 2015 by the American Academy of Pediatrics.

The objective of this study was to assess relations between fine and gross motor development and spoken language processing skills in pediatric cochlear implant users. The authors conducted a retrospective analysis of longitudinal data. Prelingually deaf children who received a cochlear implant before age 5 and had no known developmental delay or cognitive impairment were included in the study. Fine and gross motor development were assessed before implantation using the Vineland Adaptive Behavioral Scales, a standardized parental report of adaptive behavior. Fine and gross motor scores reflected a given child's motor functioning with respect to a normative sample of typically developing, normal-hearing children. Relations between these preimplant scores and postimplant spoken language outcomes were assessed. In general, gross motor scores were found to be positively related to chronologic age, whereas the opposite trend was observed for fine motor scores. Fine motor scores were more strongly correlated with postimplant expressive and receptive language scores than gross motor scores. Our findings suggest a disassociation between fine and gross motor development in prelingually deaf children: fine motor skills, in contrast to gross motor skills, tend to be delayed as the prelingually deaf children get older. These findings provide new knowledge about the links between motor and spoken language development and suggest that auditory deprivation may lead to atypical development of certain motor and language skills that share common cortical processing resources.

Despite studies of how parent-child interactions relate to early child language development, few have examined the continued contribution of parenting to more complex language skills through the preschool years. The current study explored how positive and negative parenting behaviours relate to growth in complex syntax learning from child age 3 to age 4 years, for children with typical development or developmental delays (DDs). Participants were children with or without DD (N = 60) participating in a longitudinal study of development. Parent-child interactions were transcribed and coded for parenting domains and child language. Multiple regression analyses were used to identify the contribution of parenting to complex syntax growth in children with typical development or DD. Analyses supported a final model, F(9,50) = 11.90, P < .001, including a significant three-way interaction between positive parenting behaviours, negative parenting behaviours and child delay status. This model explained 68.16% of the variance in children's complex syntax at age 4. Simple two-way interactions indicated differing effects of parenting variables for children with or without DD. Results have implications for understanding of complex syntax acquisition in young children, as well as implications for interventions. © 2018 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Early language delay phenotypes and correlation with later linguistic abilities.
Petinou, Kakia; Spanoudis, George
2014-01-01
The present study focused on examining the continuity and directionality of language skills in late talkers (LTs) and identifying factors which might contribute to language outcomes at the age of 3 years. Subjects were 23 Cypriot-Greek-speaking toddlers classified as LTs and 24 age-matched typically developing peers (TDs). Participants were assessed at 28, 32 and 36 months, using various linguistic measures such as size of receptive and expressive vocabulary, mean length of utterance (MLU) of words and number of consonants produced. Data on otitis media familial history were also analyzed. The ANOVA results indicated parallel developmental profiles between the two groups, with a language lag characterizing LTs. Concurrent correlations between measures showed that poor phonetic inventories in the LT group at 28 months predicted poor MLU at the ages of 32 and 36 months. Significant cross-lagged correlations supported the finding that poor phonetic inventories at 28 months served as a good predictor for MLU and expressive vocabulary at the age of 32 and for MLU at 36 months. The results highlight the negative effect of early language delay on language skills up to the age of 3 years and lend support to the current literature regarding the universal linguistic picture of early and persistent language delay. Based on the current results, poor phonetic inventories at the age of intake might serve as a predictive factor for language outcomes at the age of 36 months. Finally, the findings are discussed in view of the need for further research with a focus on more language-sensitive tools in testing later language outcomes. © 2014 S. Karger AG, Basel.

In the context of the established finding that theory-of-mind (ToM) growth is seriously delayed in late-signing deaf children, and some evidence of equivalent delays in those learning speech with conventional hearing aids, this study's novel contribution was to explore ToM development in deaf children with cochlear implants. Implants can substantially boost auditory acuity and rates of language growth. Despite the implant, there are often problems socialising with hearing peers and some language difficulties, lending special theoretical interest to the present comparative design. A total of 52 children aged 4 to 12 years took a battery of false belief tests of ToM. There were 26 oral deaf children, half with implants and half with hearing aids, evenly divided between oral-only versus sign-plus-oral schools. Comparison groups of age-matched high-functioning children with autism and younger hearing children were also included. No significant ToM differences emerged between deaf children with implants and those with hearing aids, nor between those in oral-only versus sign-plus-oral schools. Nor did the deaf children perform any better on the ToM tasks than their age peers with autism. Hearing preschoolers scored significantly higher than all other groups. For the deaf and the autistic children, as well as the preschoolers, rate of language development and verbal maturity significantly predicted variability in ToM, over and above chronological age. The finding that deaf children with cochlear implants are as delayed in ToM development as children with autism and their deaf peers with hearing aids or late sign language highlights the likely significance of peer interaction and early fluent communication with peers and family, whether in sign or in speech, in order to optimally facilitate the growth of social cognition and language.

To find reliability of parental or caregiver's report and testing of the Thai Speech and Language Test for Children Aged 0-4 Years Old. Five investigators assessed speech and language abilities from video both contexts: parental or caregivers' report and test forms of Thai Speech and Language Test for Children Aged 0-4 Years Old. Twenty-five normal and 30 children with delayed development or risk for delayed speech and language skills were assessed at age intervals of 3, 6, 9, 12, 15, 18, 24, 30, 36 and 48 months. Reliability of parental or caregivers' testing and reporting was at a moderate level (0.41-0.60). Inter-rater reliability among investigators was excellent (0.86-1.00). The parental or caregivers' report form of the Thai Speech and Language test for Children aged 0-4 years old was an indicator for success at a moderate level. Trained professionals could use both forms of this test as reliable tools at an excellent level.

Language acquisition with limited input: Romanian institution and foster care.
Windsor, Jennifer; Glaze, Leslie E; Koga, Sebastian F
2007-10-01
To provide the first detailed information about native language abilities of children who are or had been institutionalized. The language of ten 30-month-old children raised in Romanian orphanages was compared with that of 30 chronological-age-matched peers: 10 children who had moved recently from orphanages to foster care, 10 children in foster families for at least 1 year, and 10 children raised in their biological families. Ten language measures were obtained from communication during play and from parent/caregiver report. Children who were institutionalized and children in foster care for a brief time showed substantial language delays, with some of these children not yet producing intelligible words. Children in foster care for at least 1 year approximated the expressive output and receptive language of children who had never been institutionalized; however, they showed lower expressive grammatical abilities. Within the group of children who were institutionalized, the presence of a preferred caregiver and a measure of development, greater height, were associated with greater language output. Although children in orphanages produced fewer complex forms than children in biological families, there were no systematic qualitative differences in language structure across groups. Foster care facilitated language growth after substantial language delays associated with institutionalization.

Between five and 20% of preschool age children have language problems. These can be related to the child's hearing, socioeconomic status, intellectual development, or a psychiatric disorder. Even when it is difficult to recommend a formal screening program, family physicians can interpret delays in speech and language as "indicators" of underlying disorders. PMID:8495143

This study evaluated the extent to which developmental change in coordination of social communication in early infancy differentiates children eventually diagnosed with ASD from those not likely to develop the disorder. A prospective longitudinal design was used to compare 9 infants at heightened risk for ASD (HR) later diagnosed with ASD, to 13 HR infants with language delay, 28 HR infants with no diagnosis, and 30 low risk infants. Hierarchical Linear Modeling (HLM) analyses revealed that ASD infants exhibited significantly slower growth in coordinations overall and in gestures coordinated with vocalizations, even relative to HR infants with language delay. Disruption in the development of gesture-vocalization coordinations may result in negative cascading effects that negatively impact later social and linguistic development. PMID:25689930

The majority of a child's language development occurs in the first 5 years of life when brain development is most rapid. There are significant long-term benefits to supporting all children's language and literacy development such as maximizing their developmental potential (i.e., cognitive, linguistic, social-emotional), when children are experiencing a critical period of development (i.e., early childhood to 9 years of age). A variety of people play a significant role in supporting children's language development, including parents, guardians, family members, educators, and/or speech-language pathologists. Speech-language pathologists and educators are the professionals who predominantly support children's language development in order for them to become effective communicators and lay the foundation for later developing literacy skills (i.e., reading and writing skills). Therefore, these professionals need formal and informal assessments that provide them information on a child's understanding and/or use of the increasingly complex aspects of language in order to identify and support the receptive and expressive language learning needs of diverse children during their early learning experiences (i.e., aged 1.5 to 9 years). However, evidence on what methods and tools are being used is lacking. The authors will carry out a scoping review of the literature to identify studies and map the receptive and expressive English language assessment methods and tools that have been published and used since 1980. Arksey and O'Malley's (2005) six-stage approach to conducting a scoping review was drawn upon to design the protocol for this investigation: (1) identifying the research question; (2) identifying relevant studies; (3) study selection; (4) charting the data; (5) collating, summarizing, and reporting the results; and (6) consultation. This information will help these professionals identify and select appropriate assessment methods or tools that can be used to support development and/or identify areas of delay or difficulty and plan, implement, and monitor the progress of interventions supporting the development of receptive and expressive language skills in individuals with diverse language needs (e.g., typically developing children, children with language delays and disorders, children learning English as a second or additional language, Indigenous children who may be speaking dialects of English). Researchers plan to evaluate the effectiveness of the assessment methods or tools identified in the scoping review as an extension of this study.

In response to concerns that the Bayley Scales of Infant and Toddler Development III (BSIDIII) underestimate delay in clinical populations, this study explores developmental quotient scores as an alternative to composite scores for these children. One hundred and twenty-two children aged ≤42 months, referred for diagnosis of developmental disability from January 2007 to May 2010, were assessed, and their composite and developmental quotient scores on each scale were compared. Composite scores identified only 22% (cognitive), 27% (motor), and 47.5% (language) of children as having a developmental disability. Developmental quotient scores were significantly lower than composite scores, giving rates of developmental disability of 56.6% (cognitive), 48.4% (motor), and 74.6% (language) and more closely matching both clinical impressions of delay and the proportions of those children who were also delayed on standardized tests of adaptive function.

High prevalence/low severity language delay in preschool children born very preterm.
Foster-Cohen, Susan H; Friesen, Myron D; Champion, Patricia R; Woodward, Lianne J
2010-10-01
To examine the language development at corrected age 4 years of a regionally representative cohort of children born very preterm (VPT). Of particular interest was the identification of biological and socioenvironmental risk and protective factors that influence VPT children's early language development. Data were collected as part of a prospective longitudinal study of 110 VPT (VPT: ≤ 33 weeks gestation) and 113 full-term children (full term: 37-41 weeks gestation) born in Canterbury, New Zealand from 1998 to 2000. At corrected age 4 years, all children were assessed with the preschool version of the Clinical Evaluation of Language Fundamentals. Extensive information was also collected about children's family social background, perinatal health, childrearing environment, education/intervention exposures, and neurodevelopmental progress from birth to age 4. At the age of 4 years, VPT children were characterized by poorer receptive and expressive language development than full-term children. These differences persisted after exclusion of children with neurosensory impairment as well as statistical adjustment for the effects of social risk. Within the VPT group, the key predictors of children's overall language development were family social risk at birth (p =.05), severity of white matter abnormalities on neonatal magnetic resonance imaging (p =.49), observed parent-child synchrony (p =.001), and concurrent child cognitive ability (p =.001). Together, these factors accounted for 45% of the variance in children's total Clinical Evaluation of Language Fundamentals-Preschool scores. By preschool age, children born VPT show early emerging mild to moderate language delays that are likely to affect their school success and longer-term developmental progress. Findings highlight the importance of potentially modifiable factors such as early brain injury and parenting quality in predicting the language outcomes of children born VPT.

Imitation from 12 to 24 months in autism and typical development: A longitudinal Rasch analysis
Young, Gregory S.; Rogers, Sally J.; Hutman, Ted; Rozga, Agata; Sigman, Marian; Ozonoff, Sally
2013-01-01
The development of imitation during the second year of life plays an important role in domains of socio-cognitive development such as language and social learning. Deficits in imitation ability in persons with autism spectrum disorder (ASD) have also been repeatedly documented from toddlerhood into adulthood, raising the possibility that early disruptions in imitation contribute to the onset of ASD and the deficits in language and social interaction that define the disorder. This study prospectively examined the development of imitation between 12 and 24 months of age in 154 infants at familial risk for ASD and 78 typically developing infants who were all later assessed at 36 months for ASD or other developmental delays. The study established a developmental measure of imitation ability, and examined group differences over time, using an analytic Rasch measurement model. Results revealed a unidimensional latent construct of imitation and verified a reliable sequence of imitation skills that was invariant over time for all outcome groups. Results also showed that all groups displayed similar significant linear increases in imitation ability between 12 and 24 months and that these increases were related to individual growth in both expressive language and ratings of social engagement, but not fine motor development. The group of children who developed ASD by age 3 years exhibited delayed imitation development compared to the low-risk typical outcome group across all time-points, but were indistinguishable from other high-risk infants who showed other cognitive delays not related to ASD.

PEDIATRICS (ISSN Numbers: Print, 0031-4005; Online, 1098-4275). Published in the public domain by the American Academy of Pediatrics. Speech and language development is a useful indicator of a child's overall development and cognitive ability and is related to school success. Identification of children at risk for developmental delay or related problems may lead to intervention services and family assistance at a young age, when the chances for improvement are best. However, optimal methods for screening for speech and language delay have not been identified, and screening is practiced inconsistently in primary care. We sought to evaluate the strengths and limits of evidence about the effectiveness of screening and interventions for speech and language delay in preschool-aged children to determine the balance of benefits and adverse effects of routine screening in primary care for the development of guidelines by the US Preventive Services Task Force. The target population includes all children up to 5 years old without previously known conditions associated with speech and language delay, such as hearing and neurologic impairments. Studies were identified from Medline, PsycINFO, and CINAHL databases (1966 to November 19, 2004), systematic reviews, reference lists, and experts. The evidence review included only English-language, published articles that are available through libraries. Only randomized, controlled trials were considered for examining the effectiveness of interventions. Outcome measures were considered if they were obtained at any time or age after screening and/or intervention as long as the initial assessment occurred while the child was < or =5 years old. Outcomes included speech and language measures and other functional and health outcomes such as social behavior. A total of 745 full-text articles met our eligibility criteria and were reviewed. Data were extracted from each included study, summarized descriptively, and rated for quality by using criteria specific to different study designs developed by the US Preventive Services Task Force. The use of risk factors for selective screening has not been evaluated, and a list of specific risk factors to guide primary care physicians has not been developed or tested. Sixteen studies about potential risk factors for speech and language delay in children enrolled heterogeneous populations, had dissimilar inclusion and exclusion criteria, and measured different risk factors and outcomes. The most consistently reported risk factors included a family history of speech and language delay, male gender, and perinatal factors. Other risk factors reported less consistently included educational levels of the mother and father, childhood illnesses, birth order, and family size. The performance characteristics of evaluation techniques that take < or =10 minutes to administer were described in 24 studies relevant to screening. Studies that were rated good to fair quality reported wide ranges of sensitivity and specificity when compared with reference standards (sensitivity: 17-100%; specificity: 45-100%). Most of the evaluations, however, were not designed for screening purposes, the instruments measured different domains, and the study populations and settings were often outside of primary care. No "gold standard" has been developed and tested for screening, reference standards varied across studies, few studies compared the performance of > or =2 screening techniques in 1 population, and comparisons of a single screening technique across different populations are lacking. Fourteen good- and fair-quality randomized, controlled trials of interventions reported significantly improved speech and language outcomes compared with control groups. Improvement was demonstrated in several domains including articulation, phonology, expressive language, receptive language, lexical acquisition, and syntax among children in all age groups studied and across multiple therapeutic settings. Improvement in other functional outcomes such as socialization skills, self-esteem, and improved play themes were demonstrated in some, but not all, of the 4 studies that measured them. In general, studies of interventions were small and heterogeneous, may be subject to plateau effects, and reported short-term outcomes based on various instruments and measures. As a result, long-term outcomes are not known, interventions could not be compared directly, and generalizability is questionable. Use of risk factors to guide selective screening is not supported by studies. Several aspects of screening have been inadequately studied to determine optimal methods, including which instrument to use, the age at which to screen, and which interval is most useful. Trials of interventions demonstrate improvement in some outcome measures, but conclusions and generalizability are limited. Data are not available addressing other key issues including the effectiveness of screening in primary care settings, role of enhanced surveillance by primary care physicians before referral for diagnostic evaluation, non-speech and language and long-term benefits of interventions, and adverse effects of screening and interventions.

For optimal development young children need warm, responsive, enriched and communicative environments for learning social, language, and other skills. Infants and toddlers exposed to psychosocial risk lack enriched environments and may present with communication delays. To investigate the relationship between psychosocial risks and communication delays in infants from underserved communities in South Africa. Primary healthcare facilities in Tshwane district, South Africa. A parent interview and Rossetti Infant Toddler Language Scales were used to collect data from caregivers of 201 infants aged 6–12 months, selected through convenience sampling. Associations between communication delays and risks were determined (Chi-square and Fisher's exact tests). A log-linear model analysis was used to model the simultaneous effect of significant risks on the probability of having communication delays. Communication delays were present in 13% of infants. Infants with two or more siblings, born from mothers aged 18–29 years who own their house, had a 39% chance of presenting with communication delays. Developmental screening and early intervention is important in primary healthcare contexts in South Africa, as a clear relationship has been established between three risk factors and communication delays in infants.

A majority of the children with Prader-Willi syndrome (PWS) have global developmental delay and mental delay. The aim of this study was to investigate the developmental profiles and mental assessments among preschool children with PWS. Ten children with PWS between the ages of 15 months to 6 years, and 11 children with typical development were enrolled. Developmental profiles in terms of their developmental quotient (DQ) for the eight domains of the Chinese Children Developmental Inventory (CCDI) and mental assessments in terms of intelligence quotient (IQ) and developmental index (DI) were carried out for all children. The DQs of all eight domains, including gross motor, fine motor, expressive language, concept comprehension, situation comprehension, self help, personal- social and general development, in the PWS group were lower than the DQs of the children from the typical development group (p < 0.01). Children with PWS had better DQs in the fine motor domain than in the gross motor domain and in the receptive language domain than in the expressive language domain. Furthermore, their verbal IQ were better than their performance IQ and their mental DI was better than their psychomotor DI. These findings suggest that the children with PWS show an uneven global developmental delay together with an uneven mental delay. The results of this study should allow clinicians to better understand the developmental functioning of children with PWS and this will help with the planning of treatment strategies.

To assess children with retinopathy-positive cerebral malaria (CM) for neurocognitive sequelae. Participants were selected from an ongoing exposure-control study. Eighty-three Malawian children averaging 4.4 years of age and diagnosed with retinopathy-positive CM were compared to 95 controls. Each child was classified as delayed or not using age-based norms for the Malawi Developmental Assessment Tool (MDAT) for developmental delay on the total scale and for the domains of gross motor, fine motor, language and social skills. Groups were also compared on the Achenbach Child Behaviour Checklist (CBCL) (1.5-5 years). Children with retinopathy-positive CM were delayed, relative to the comparison group, on MDAT total development (P = 0.028; odds ratio or OR = 2.13), with the greatest effects on language development (P = 0.003; OR = 4.93). The two groups did not differ significantly on the Achenbach CBCL internalizing and externalizing symptoms total scores. Stepwise regression demonstrated that coma duration, seizures while in hospital, platelet count and lactate level on admission were predictive of assessment outcomes for the children with retinopathy-positive CM. Children who suffer retinopathy-positive CM at preschool age are at greater risk of developmental delay, particularly with respect to language development. This confirms previous retrospective study findings with school-age children evaluated years after acute illness. The MDAT and the Achenbach CBCL proved sensitive to clinical indicators of severity of malarial illness. © 2010 Blackwell Publishing Ltd.

Moderate and late preterm (MLPT) births comprise most preterm infants. Therefore, long-term developmental concerns in this population potentially have a large public health influence. While there are increasing reports of developmental problems in MLPT children, detail is lacking on the precise domains that are affected. To compare neurodevelopment and social-emotional development between MLPT infants and term-born control infants at age 2 years. This investigation was a prospective longitudinal cohort study at a single tertiary hospital. Participants were MLPT infants (32-36 weeks' completed gestation) and healthy full-term controls (≥37 weeks' gestation) recruited at birth. During a 3-year period between December 7, 2009, and November 7, 2012, MLPT infants were recruited at birth from the neonatal unit and postnatal wards of the Royal Women's Hospital, Melbourne, Australia. The term control recruitment extended to March 26, 2014. The dates of the data developmental assessments were February 23, 2012, to April 8, 2016. Moderate and late preterm birth. Cerebral palsy, blindness, and deafness assessed by a pediatrician; cognitive, language, and motor development assessed using the Bayley Scales of Infant Development-Third Edition (developmental delay was defined as less than -1 SD relative to the mean in controls in any domain of the scales); and social-emotional and behavioral problems assessed by a parent questionnaire (Infant Toddler Social Emotional Assessment). Outcomes were compared between birth groups using linear and logistic regression, adjusted for social risk. In total, 198 MLPT infants (98.5% of 201 recruited) and 183 term-born controls (91.0% of 201 recruited) were assessed at 2 years' corrected age. Compared with controls, MLPT children had worse cognitive, language, and motor development at age 2 years, with adjusted composite score mean differences of -5.3 (95% CI, -8.2 to -2.4) for cognitive development, -11.4 (95% CI, -15.3 to -7.5) for language development, and -7.3 (95% CI, -10.6 to -3.9) for motor development. The odds of developmental delay were higher in the MLPT group compared with controls, with adjusted odds ratios of 1.8 (95% CI, 1.1-3.0) for cognitive delay, 3.1 (95% CI, 1.8-5.2) for language delay, and 2.4 (95% CI, 1.3-4.5) for motor delay. Overall social-emotional competence was worse in MLPT children compared with controls (t statistic mean difference, -3.6 (95% CI, -5.8 to -1.4), but other behavioral domains were similar. The odds of being at risk for social-emotional competence were 3.9 (95% CI, 1.4-10.9) for MLPT children compared with controls. Moderate and late preterm children exhibited developmental delay compared with their term-born peers, most marked in the language domain. This knowledge of developmental needs in MLPT infants will assist in targeting surveillance and intervention.

This longitudinal study investigated temporal auditory processing (frequency modulation and between-channel gap detection) and speech perception (speech-in-noise and categorical perception) in three groups of 6 years 3 months to 6 years 8 months-old children attending grade 1: (1) children with specific language impairment (SLI) and literacy delay (n = 8), (2) children with SLI and normal literacy (n = 10) and (3) typically developing children (n = 14). Moreover, the relations between these auditory processing and speech perception skills and oral language and literacy skills in grade 1 and grade 3 were analyzed. The SLI group with literacy delay scored significantly lower than both other groups on speech perception, but not on temporal auditory processing. Both normal reading groups did not differ in terms of speech perception or auditory processing. Speech perception was significantly related to reading and spelling in grades 1 and 3 and had a unique predictive contribution to reading growth in grade 3, even after controlling reading level, phonological ability, auditory processing and oral language skills in grade 1. These findings indicated that speech perception also had a unique direct impact upon reading development and not only through its relation with phonological awareness. Moreover, speech perception seemed to be more associated with the development of literacy skills and less with oral language ability. Copyright © 2011 Elsevier Ltd. All rights reserved.

Siblings of children with autism (sibs-A) are at increased genetic risk for autism spectrum disorders (ASD) and milder impairments. To elucidate diversity and contour of early developmental trajectories exhibited by sibs-A, regardless of diagnostic classification, latent class modeling was used. Sibs-A (N = 204) were assessed with the Mullen Scales of Early Learning from age 6 to 36 months. Mullen T scores served as dependent variables. Outcome classifications at age 36 months included: ASD (N = 52); non-ASD social/communication delay (broader autism phenotype; BAP; N = 31); and unaffected (N = 121). Child-specific patterns of performance were studied using latent class growth analysis. Latent class membership was then related to diagnostic outcome through estimation of within-class proportions of children assigned to each diagnostic classification. A 4-class model was favored. Class 1 represented accelerated development and consisted of 25.7% of the sample, primarily unaffected children. Class 2 (40.0% of the sample), was characterized by normative development with above-average nonverbal cognitive outcome. Class 3 (22.3% of the sample) was characterized by receptive language, and gross and fine motor delay. Class 4 (12.0% of the sample), was characterized by widespread delayed skill acquisition, reflected by declining trajectories. Children with an outcome diagnosis of ASD were spread across Classes 2, 3, and 4. Results support a category of ASD that involves slowing in early non-social development. Receptive language and motor development is vulnerable to early delay in sibs-A with and without ASD outcomes. Non-ASD sibs-A are largely distributed across classes depicting average or accelerated development. Developmental trajectories of motor, language, and cognition appear independent of communication and social delays in non-ASD sibs-A. © 2012 The Authors.

expressive language of pre-term children. to compare the expressive vocabulary of two year-old children born prematurely, to that of those born at term. the study sample was composed by 118 speech-language assessment protocols, divided in two groups: the pre-term group (PTG) composed by 58 underweight premature children followed by a multi-professional team at the Casa do Prematuro (House of Premature Children) at Unifesp, and the full-term group (FTG) composed by 60 full-term born children. In order to evaluate the expressive language of these children, the Lave - Lista de Avaliação do Vocabulário Expressivo (Assessment List of the Expressive Vocabulary) was used. The Lave is an adaptation of the LDS - Language Development Survey - for the Brazilian Portuguese Language. The Lave investigates the expressive language and detects delays in oral language. children born underweight and prematurely present a greater occurrence of expressive language delay, 27.6%. These pre-term children present significantly lower expressive vocabulary and phrasal extension than children of the same age born at full-term in all semantic categories. Family income proved to be positively associated to phrasal extension, as well as to gestational age and weight at birth; thus indicating the effect of these adverse conditions still during the third year of age. The audiological status was associated to word utterances in the PTG. children born prematurely and underweight are at risk in terms of vocabulary development; this determines the need for speech-therapy intervention programs.

The aim of this study was to develop and content validate specific speech and language intervention picture cards: The Letter-Sound (L&S) cards. The present study was also focused on assessing the influence of these cards on letter-sound correspondences and speech sound production. An expert panel of six speech and language therapists analysed and discussed the L&S cards based on several criteria previously established. A Speech and Language Therapist carried out a 6-week therapeutic intervention with a group of seven Portuguese phonologically delayed pre-schoolers aged 5;3 to 6;5. The modified Bland-Altman method revealed good agreement among evaluators, that is the majority of the values was between the agreement limits. Additional outcome measures were collected before and after the therapeutic intervention process. Results indicate that the L&S cards facilitate the acquisition of letter-sound correspondences. Regarding speech sound production, some improvements were also observed at word level. The L&S cards are therefore likely to give phonetic cues, which are crucial for the correct production of therapeutic targets. These visual cues seemed to have helped children with phonological delay develop the above-mentioned skills.

To evaluate the relationship between abnormal feeding patterns and language performance on the Bayley Scales of Infant Development-Third Edition at 18-22 months adjusted age among a cohort of extremely premature infants. This is a descriptive analysis of 1477 preterm infants born ≤ 26 weeks gestation or enrolled in a clinical trial between January 1, 2006 and March 18, 2008 at a National Institute of Child Health and Human Development Neonatal Research Network center who completed the 18-month neurodevelopmental follow-up assessment. At 18-22 months adjusted age, a comprehensive neurodevelopmental evaluation was performed by certified examiners including the Receptive and Expressive Language Subscales of the Bayley Scales of Infant Development-Third Edition and a standardized adjusted age feeding behaviors and nutritional intake. Data were analyzed using bivariate and multilevel linear and logistic regression modeling. Abnormal feeding behaviors were reported in 193 (13%) of these infants at 18-22 months adjusted age. Abnormal feeding patterns, days of mechanical ventilation, hearing impairment, and Gross Motor Functional Classification System level ≥ 2 each independently predicted lower composite language scores. At 18 months adjusted age, premature infants with a history of feeding difficulties are more likely to have language delay. Neuromotor impairment and days of mechanical ventilation are both important risk factors associated with these outcomes. Copyright © 2013 Mosby, Inc. All rights reserved.

Three converging lines of evidence have suggested that cerebellar abnormality is implicated in developmental language and literacy problems. First, some brain imaging studies have linked abnormalities in cerebellar grey matter to dyslexia and specific language impairment (SLI). Second, theoretical accounts of both dyslexia and SLI have postulated impairments of procedural learning and automatisation of skills, functions that are known to be mediated by the cerebellum. Third, motor learning has been shown to be abnormal in some studies of both disorders. We assessed the integrity of face related regions of the cerebellum using Pavlovian eyeblink conditioning in 7–11 year-old children with SLI. We found no relationship between oral language skills or literacy skills with either delay or trace conditioning in the children. We conclude that this elementary form of associative learning is intact in children with impaired language or literacy development. PMID:24139661

Little is known about cognition in preschoolers with ADHD and language delay (LD). The objective was to investigate cognitive functions in preschoolers with ADHD symptoms and LD compared with children with ADHD symptoms only and to estimate the frequency of children with ADHD symptoms, co-occurring language delay, and delays on cognitive measures. Participants were recruited from the Norwegian Mother and Child Cohort Study. The teacher report of expressive language and the cognitive tests from 119 3-year-old children with parent reported ADHD symptoms and LD were compared with those of 258 children with ADHD symptoms only. The ADHD + LD group performed significantly worse than the ADHD group on most language-related measures. There were no differences between the groups on most nonverbal measures. Single measures had a limited potential of differentiating between the groups. ADHD symptoms and co-occurring LD in preschoolers were characterized by cognitive deficits associated with both disorders, not with global neurodevelopmental delay. © The Author(s) 2013.

Children with autism have delays in the development of theory of mind. However, the sub-group of children with autism who have little or no language have gone untested since false belief tests (FB) typically involve language. FB understanding has been reported to be intact in children with specific language impairment (SLI). This raises the possibility that a non-verbal FB test would distinguish children with autism vs. children with SLI. The present study tested two predictions: (1) FB understanding is to some extent independent of language ability; and (2) Children with autism with low language levels show specific impairment in theory of mind. Results confirmed both predictions. Results are discussed in terms of the role of language in the development of mindreading.

Adult-provided language shapes event memory in children who are preverbal and in those who are able to discuss the past using language. The research conducted to date, however, has not yet established whether infant language comprehension abilities moderate the extent to which preverbal infants benefit from adult-provided supportive language. The present study was conducted to address this question by examining immediate imitation and 1-week delayed generalization across cues in 20-month-old infants as a function of (a) variability in adult-provided linguistic support at encoding and test, (b) infant language comprehension abilities, and (c) their interaction. The provision of supportive adult language at encoding and test was associated with delayed generalization across cues although supportive adult language at encoding did not influence performance at immediate imitation. Infant language comprehension abilities were associated with performance at immediate imitation and delayed generalization across cues. In addition, infant language comprehension abilities moderated the extent to which infants benefited from adult-provided supportive language at encoding and test. The findings contribute to the literature by demonstrating that adult language use and infant language comprehension are independently and differentially associated with immediate imitation and 1-week delayed generalization across cues but also serve to jointly structure event memory in the second year of life.

Language and literacy development of deaf and hard-of-hearing children: successes and challenges.
Lederberg, Amy R; Schick, Brenda; Spencer, Patricia E
2013-01-01
Childhood hearing loss presents challenges to language development, especially spoken language. In this article, we review existing literature on deaf and hard-of-hearing (DHH) children's patterns and trajectories of language as well as development of theory of mind and literacy. Individual trajectories vary significantly, reflecting access to early identification/intervention, advanced technologies (e.g., cochlear implants), and perceptually accessible language models. DHH children develop sign language in a similar manner as hearing children develop spoken language, provided they are in a language-rich environment. This occurs naturally for DHH children of deaf parents, who constitute 5% of the deaf population. For DHH children of hearing parents, sign language development depends on the age that they are exposed to a perceptually accessible 1st language as well as the richness of input. Most DHH children are born to hearing families who have spoken language as a goal, and such development is now feasible for many children. Some DHH children develop spoken language in bilingual (sign-spoken language) contexts. For the majority of DHH children, spoken language development occurs in either auditory-only contexts or with sign supports. Although developmental trajectories of DHH children with hearing parents have improved with early identification and appropriate interventions, the majority of children are still delayed compared with hearing children. These DHH children show particular weaknesses in the development of grammar. Language deficits and differences have cascading effects in language-related areas of development, such as theory of mind and literacy development.

The Two-Word Stage: Motivated by Linguistic or Cognitive Constraints?
Berk, Stephanie; Lillo-Martin, Diane
2012-01-01
Child development researchers often discuss a “two-word” stage during language acquisition. However, there is still debate over whether the existence of this stage reflects primarily cognitive or linguistic constraints. Analyses of longitudinal data from two Deaf children, Mei and Cal, not exposed to an accessible first language (American Sign Language - ASL) until the age of 6 years, suggest that a linguistic constraint is observed when cognition is relatively spared. These older children acquiring a first language after delayed exposure exhibit aspects of a two-word stage of language development. Results from intelligence assessments, achievement tests, drawing tasks, and qualitative cognitive analyses show that Mei and Cal are at least of average intelligence and ability. However, results from language analyses clearly show differences from both age peers and younger native signers in the early two-word stage, providing new insights into the nature of this phase of language development.

Bilingualism, dementia, cognitive and neural reserve.
Perani, Daniela; Abutalebi, Jubin
2015-12-01
We discuss the role of bilingualism as a source of cognitive reserve and we propose the putative neural mechanisms through which lifelong bilingualism leads to a neural reserve that delays the onset of dementia. Recent findings highlight that the use of more than one language affects the human brain in terms of anatomo-structural changes. It is noteworthy that recent evidence from different places and cultures throughout the world points to a significant delay of dementia onset in bilingual/multilingual individuals. This delay has been reported not only for Alzheimer's dementia and its prodromal mild cognitive impairment phase, but also for other dementias such as vascular and fronto-temporal dementia, and was found to be independent of literacy, education and immigrant status. Lifelong bilingualism represents a powerful cognitive reserve delaying the onset of dementia by approximately 4 years. As to the causal mechanism, because speaking more than one language heavily relies upon executive control and attention, brain systems handling these functions are more developed in bilinguals resulting in increases of gray and white matter densities that may help protect from dementia onset. These neurocognitive benefits are even more prominent when second language proficiency and exposure are kept high throughout life.

The purpose of this study was to examine the influence of phonotactic probability on sublexical (phonological) and lexical representations in 3-year-olds who had a history of being late talkers in comparison with their peers with typical language development. Ten 3-year-olds who were late talkers and 10 age-matched typically developing controls completed nonword repetition and fast mapping tasks; stimuli for both experimental procedures differed in phonotactic probability. Both participant groups repeated nonwords containing high phonotactic probability sequences more accurately than nonwords containing low phonotactic probability sequences. Participants with typical language showed an early advantage for fast mapping high phonotactic probability words; children who were late talkers required more exposures to the novel words to show the same advantage for fast mapping high phonotactic probability words. Children who were late talkers showed similar sensitivities to phonotactic probability in nonword repetition and word learning when compared with their peers with no history of language delay. However, word learning in children who were late talkers appeared to be slower when compared with their peers.

In Experiment 1, classroom teachers were taught to delay their offers of help in naturally occurring situations, and thereby to provide additional opportunities for language use by six moderately retarded language-delayed children. The teachers introduced this delay technique in a multiple-baseline design across the six children. As delays were used, child verbal initiations increased. Follow-up assessment showed that teachers were maintaining greater than baseline levels of the delay technique after 10 weeks. Experiment 2 replicated the findings of Experiment 1, and included a more thorough maintenance assessment, while focusing on teachers' generalization of the delay technique. Teachers were found to generalize their use of delay to 56% of their monitored untaught opportunities. The two experiments show that (a) the delay technique is quick to teach and simple to implement, (b) delays do provide opportunities for children to initiate, (c) teachers can generalize their use of delay to novel self-selected situations, and (d) teachers can maintain their use of delays over time.

Children with autism are often described as having deficient play skills, particularly symbolic play. We compared the play of 35 children with autism to 38 children with other developmental delays. All children were preschool-age and produced less than 20 different words. Results indicated no significant differences across the two groups in their play. Children with autism engaged in more conventional play, that is, putting objects together according to how the toys were constructed (e.g., pieces in a puzzle, lid on a teapot). Results also indicated high correlations between play, language, and cognitive measures. Findings indicate that play relates to language and cognitive levels yet may not discriminate children with autism and children with other developmental delays early in their development.

Delayed language development may be an early indicator of autism spectrum disorder (ASD). Early intervention is critical for children with ASD, and the present study presents pilot data on a clinical trial of omega-3 and -6 fatty acid supplementation and language development, a secondary trial outcome, in children at risk for ASD. We randomized 31 children to receive an omega-3 and -6 supplement or a placebo for 3 months, and measured their language abilities at baseline and after supplementation. Gesture use, but not word production, increased for children in the treatment group more than children in the placebo group. These results suggest possible effectiveness of omega-3 and -6 supplementation for language development in children at risk for ASD.

2017-09-01
Objective Describe the impact of hearing loss, tympanostomy tube placement before palatoplasty, and number of tubes received on speech outcomes in children with cleft palate. Study Design Case series with chart review. Setting Tertiary care children's hospital. Subjects and Methods Records from 737 children born between April 2005 and April 2015 who underwent palatoplasty at a tertiary children's hospital were reviewed. Exclusion criteria were cleft repair at an outside hospital, intact secondary palate, absence of postpalatoplasty speech evaluation, sensorineural or mixed hearing loss, no tubes, first tubes after palatoplasty, or first clinic after 12 months of age. Data from 152 patients with isolated cleft palate and 166 patients with cleft lip and palate were analyzed using Wilcoxon rank-sum, χ 2 , and Fisher exact test and logistic regression. Results Most patients (242, 76.1%) received tubes before palatoplasty. Hearing loss after tubes, but not before, was associated with speech/language delays at 24 months ( P = .005) and language delays ( P = .048) and speech sound production disorders (SSPDs, P = .040) at 5 years. Receiving tubes before palatoplasty was associated with failed newborn hearing screen ( P = .001) and younger age at first posttubes type B tympanogram with normal canal volume ( P = .015). Hearing loss after tubes ( P = .021), language delays ( P = .025), SSPDs ( P = .003), and velopharyngeal insufficiency ( P = .032) at 5 years and speech surgery ( P = .022) were associated with more tubes. Conclusion Continued middle ear disease, reflected by hearing loss and multiple tubes, may impair speech and language development. Inserting tubes before palatoplasty did not mitigate these impairments better than later tube placement.

Why talk with children matters: clinical implications of infant- and child-directed speech research.
Ratner, Nan Bernstein
2013-11-01
This article reviews basic features of infant- or child-directed speech, with particular attention to those aspects of the register that have been shown to impact profiles of child language development. It then discusses concerns that arise when describing adult input to children with language delay or disorder, or children at risk for depressed language skills. The article concludes with some recommendations for parent counseling in such cases, as well as methods that speech-language pathologists can use to improve the quality and quantity of language input to language-learning children.

Prenatal exposure to dioxins and PCBs is potentially harmful to the developing fetus and may increase the risk of delayed or impaired neurodevelopment. Several studies have reported negative associations between prenatal exposure to these compounds and aspects of cognition related to language in early childhood. The aim was to examine the association between maternal low level dietary exposure to dioxins and PCB during pregnancy and language development in 3year old children in a large group of mother-child pairs participating in the Norwegian Mother and Child Cohort Study (MoBa). This study includes 44,092 children of women who were recruited to the Norwegian Mother and Child Cohort Study (MoBa) during the years 2002-2009. Maternal dietary exposure to dioxins and PCBs was estimated based on a validated food frequency questionnaire (FFQ) answered mid-pregnancy and a database of dioxin and PCB concentrations in Norwegian foods. Exposure to dioxins and dioxin-like PCBs (dl-compounds) was expressed in total toxic equivalents (TEQ), and PCB-153 was used as marker for non-dioxin-like PCBs (ndlPCBs). Children's language skills at age 3 were assessed by parental report including a Dale and Bishop grammar rating and questions about communication skills from the Ages and Stages Questionnaire (ASQ). Logistic regression models adjusted for confounders were used to examine the association between maternal dietary exposure to dl-compounds or PCB-153 and language development in children. The maternal dietary exposure to dl-compounds and PCB-153 was generally low, and 98% of women had intakes of dl-compounds ≤14pg TEQ/kg bw/week, which is the tolerable weekly intake set by EU's Scientific Committee for Food (SCF). High maternal exposure (>14pg TEQ/kg bw/week of dl-compounds (median 2.6pg/kg bw/day, range 2-16) or >97.5-percentile intake of PCB-153 (median 11ng/kg bw/day, range 5-28) was associated with higher odds of incomplete grammar (in boys and girls, adjusted ORs 1.1 to 1.3) and severe language delay in girls, adjusted ORs 2.8 [95% CI 1.1, 7.1] for PCB-153 and 2.9 [95% CI 1.4, 5.9] for dl-compounds. Furthermore, high exposure to dl-compounds was associated with moderate language delay 1.4 [95% CI 1.0, 2.0] and lower communication score (ASQ), adjusted OR 1.4 [95% CI 1.1, 1.9] in girls. The main findings of this study were: 1) Girls born to mothers who exceeded the tolerable weekly intake for dl-compounds or had a PCB-153 intake above the 97.5 percentile in early pregnancy may have increased risk of language delay at age 3years. 2) Negative associations with maternal exposure to dl-compounds or PCB-153 were observed for both boys and girls having incomplete grammar, which is a subtle reduction in language skills. This interesting finding should not be considered as deviant at this age. Copyright © 2016 Elsevier Ltd. All rights reserved.

Screening for Speech and Language Delay in Children 5 Years Old and Younger: A Systematic Review.
Wallace, Ina F; Berkman, Nancy D; Watson, Linda R; Coyne-Beasley, Tamera; Wood, Charles T; Cullen, Katherine; Lohr, Kathleen N
2015-08-01
No recommendation exists for or against routine use of brief, formal screening instruments in primary care to detect speech and language delay in children through 5 years of age. This review aimed to update the evidence on screening and treating children for speech and language since the 2006 US Preventive Services Task Force systematic review. Medline, the Cochrane Library, PsycInfo, Cumulative Index to Nursing and Allied Health Literature, ClinicalTrials.gov, and reference lists. We included studies reporting diagnostic accuracy of screening tools and randomized controlled trials reporting benefits and harms of treatment of speech and language. Two independent reviewers extracted data, checked accuracy, and assigned quality ratings using predefined criteria. We found no evidence for the impact of screening on speech and language outcomes. In 23 studies evaluating the accuracy of screening tools, sensitivity ranged between 50% and 94%, and specificity ranged between 45% and 96%. Twelve treatment studies improved various outcomes in language, articulation, and stuttering; little evidence emerged for interventions improving other outcomes or for adverse effects of treatment. Risk factors associated with speech and language delay were male gender, family history, and low parental education. A limitation of this review is the lack of well-designed, well-conducted studies addressing whether screening for speech and language delay or disorders improves outcomes. Several screening tools can accurately identify children for diagnostic evaluations and interventions, but evidence is inadequate regarding applicability in primary care settings. Some treatments for young children identified with speech and language delays and disorders may be effective. Copyright © 2015 by the American Academy of Pediatrics.

Dyer, C; Hadden, A J
1981-01-01
Attention has recently focused on the need to build up a corpus of case observations relating to the function of delayed echolalia in various handicapping conditions but especially in early childhood autism. This present article offers six functional categories as an aid to clear reporting of observation and, thus clarification of this little-understood facet of deviant language development.

Comparing Motor Skills in Autism Spectrum Individuals With and Without Speech Delay
Barbeau, Elise B.; Meilleur, Andrée‐Anne S.; Zeffiro, Thomas A.
2015-01-01
Movement atypicalities in speed, coordination, posture, and gait have been observed across the autism spectrum (AS) and atypicalities in coordination are more commonly observed in AS individuals without delayed speech (DSM‐IV Asperger) than in those with atypical or delayed speech onset. However, few studies have provided quantitative data to support these mostly clinical observations. Here, we compared perceptual and motor performance between 30 typically developing and AS individuals (21 with speech delay and 18 without speech delay) to examine the associations between limb movement control and atypical speech development. Groups were matched for age, intelligence, and sex. The experimental design included: an inspection time task, which measures visual processing speed; the Purdue Pegboard, which measures finger dexterity, bimanual performance, and hand‐eye coordination; the Annett Peg Moving Task, which measures unimanual goal‐directed arm movement; and a simple reaction time task. We used analysis of covariance to investigate group differences in task performance and linear regression models to explore potential associations between intelligence, language skills, simple reaction time, and visually guided movement performance. AS participants without speech delay performed slower than typical participants in the Purdue Pegboard subtests. AS participants without speech delay showed poorer bimanual coordination than those with speech delay. Visual processing speed was slightly faster in both AS groups than in the typical group. Altogether, these results suggest that AS individuals with and without speech delay differ in visually guided and visually triggered behavior and show that early language skills are associated with slower movement in simple and complex motor tasks.

Speech-language and educational consequences of unilateral hearing loss in children.
Lieu, Judith E Cho
2004-05-01
In the past, unilateral hearing loss (UHL) in children was thought to have little consequence because speech and language presumably developed appropriately with one normal-hearing ear. Some studies from the 1980s and 1990s have suggested that a significantly increased proportion of children with UHL may have educational and/or behavioral problems, compared with their normal-hearing peers. Limited data exist about the effect of UHL on acquisition of speech and language skills. To review the current literature about the impact UHL has on the development of speech and language and educational achievement. MEDLINE search between 1966 and June 1, 2003, using the medical subject heading "hearing loss," combined with the textword "unilateral." Studies were limited to those written in English, reporting speech-language and/or educational results in children. Articles were read with attention to study design, population, recruitment of subjects, and outcomes measured. Problems in school included a 22% to 35% rate of repeating at least one grade, and 12% to 41% receiving additional educational assistance. Speech and language delays have been reported in some but not all studies. School-age children with UHL appear to have increased rates of grade failures, need for additional educational assistance, and perceived behavioral issues in the classroom. Speech and language delays may occur in some children with UHL, but it is unclear if children "catch up" as they grow older. Research into this area is necessary to clarify these issues and to determine whether interventions may prevent potential problems.

Metabolic correlates of learning disability.
Nyhan, W L; Wulfeck, B B; Tallal, P; Marsden, D L
1989-01-01
To summarize, the neuropsychologic findings in MSUD and MMA children in both groups demonstrated deficits in cognitive/language areas, but interesting individual differences existed. For example, a marked contrast in abilities existed between NT and GV, even taking into account the age difference between these children with MSUD. While NT's general intellectual functioning was within the low-average range, GV was severely impaired. In more specific areas of cognitive functioning, NT had an uneven performance profile with areas of strengths and weaknesses, while GV evidenced a flat profile with significant impairment in all areas. NT demonstrated mild delay in visual-spatial processing, articulation development, motor-speech abilities, and selective attention and concentration; however, his language and psychosocial development were within the broad range of normality. In contrast, GV exhibited severe dysfunction in speech, language, and perceptual/conceptual development. The three children with MMA also exhibited a range of disabilities in cognitive functioning. TJ and SH contrasted in the degree of developmental delay across language and cognitive domains. Both were distractible and exhibited very short attention spans but there was a measurable difference in the extent of their speech, language, visual-spatial development. CH was markedly delayed in all areas of cognitive development, which is consistent with global retardation. The severity of her disease and its probable impact on brain development were undoubtedly related to her intellectual impairment. These datasets illustrate the challenges we face, because within each group we see a range of impairment. Nevertheless, we are optimistic that our efforts to relate metabolic, anatomic and neuropsychologic findings for such children will lead to a better understanding of these disorders. We are hopeful that this will result in new advances in diagnosis and intervention, which will ultimately improve the prognosis for cognitive development. In summary, a multidisciplinary center has been established at UCSD to study the neurologic basis of disorders of language, learning and behavior in infants and children. The center draws together a group of researchers from many fields including neurology, biochemistry, pediatrics, cognitive and developmental neuropsychology, psycholinguistics, neurophysiology and communicative disorders. Because of the diverse interests and expertise of our group, it is hoped to forge a synthesis of the behavioral and neurosciences to study populations of children with a variety of neurologic, metabolic, and language/learning disorders. Disorders currently under study include Lesch-Nyhan disease, oculocutaneous tyrosinemia, propionic acidemia, carnitine palmityl transferase deficiency, Schwachman-Diamond syndrome, histidinemia, Hartnup disease, citrullinemia, galactosemia, maple syrup urine disease, and methylmalonic acidemia.(ABSTRACT TRUNCATED AT 400 WORDS)

To determine the importance of prelinguistic babbling by studying patterns of speech and language development after cricotracheal resection in aphonic children. Retrospective review of seven previously aphonic children who underwent cricotracheal resection by our pediatric thoracic airway team. The analyzed variables include age, sex, comorbidity, grade of stenosis, length of resected trachea, and communication methods. Data regarding the children's pre- and postsurgical communication methods, along with their utilization of speech therapy services, were obtained via speech-language pathology evaluations, clinical observations, and a standardized telephone survey supplemented by parental documentation. Postsurgical voice quality was assessed using the Pediatric Voice Outcomes Survey. All seven subjects underwent tracheostomy prior to 2 months of age when corrected for prematurity. The subjects remained aphonic for the entire duration of cannulation. Following cricotracheal resection, they experienced an initial delay in speech acquisition. Vegetative functions were the first laryngeal sounds to emerge. Initially, the children were only able to produce these sounds reflexively, but they subsequently gained voluntary control over these laryngeal functions. All subjects underwent an identifiable stage of canonical babbling that often occurred concomitantly with vocalizations. This was followed by the emergence of true speech. The initial delay in speech acquisition observed following decannulation, along with the presence of a postsurgical canonical stage in all study subjects, supports the hypothesis that babbling is necessary for speech and language development. Furthermore, the presence of babbling is universally evident regardless of the age at which speech develops. Finally, there is no demonstrable correlation between preoperative sign language and rate of speech development.

The impact of input quality on early sign development in native and non-native language learners.
Lu, Jenny; Jones, Anna; Morgan, Gary
2016-05-01
There is debate about how input variation influences child language. Most deaf children are exposed to a sign language from their non-fluent hearing parents and experience a delay in exposure to accessible language. A small number of children receive language input from their deaf parents who are fluent signers. Thus it is possible to document the impact of quality of input on early sign acquisition. The current study explores the outcomes of differential input in two groups of children aged two to five years: deaf children of hearing parents (DCHP) and deaf children of deaf parents (DCDP). Analysis of child sign language revealed DCDP had a more developed vocabulary and more phonological handshape types compared with DCHP. In naturalistic conversations deaf parents used more sign tokens and more phonological types than hearing parents. Results are discussed in terms of the effects of early input on subsequent language abilities.

Children with congenital visual impairment have been reported to be delayed in theory of mind development. So far, research focused on first-order theory of mind, and included mainly blind children, whereas the majority of visually impaired children is not totally blind. The present study set out to explore whether children with a broader range of congenital visual impairments have a delay in more advanced theory of mind understanding, in particular second-order theory of mind (i.e. awareness that other people have beliefs about beliefs) and non-literal language (e.g. irony or figure of speech). Twenty-four children with congenital visual impairment and 24 typically developing sighted children aged between 6 and 13 were included. All children were presented with a series of stories involving understanding of theory of mind and non-literal language. When compared with sighted children of similar age and verbal intelligence, performance of children with congenital visual impairment on advanced theory of mind and non-literal stories was alike. The ability to understand the motivations behind non-literal language was associated with age, verbal intelligence and theory of mind skills, but was not associated with visual ability.

The development of young siblings of children with autism from 4 to 54 months.
Gamliel, Ifat; Yirmiya, Nurit; Sigman, Marian
2007-01-01
Cognitive and language skills of 39 siblings of children with autism (SIBS-A) and 39 siblings of typically developing children (SIBS-TD) at ages 4, 14, 24, 36, and 54 months were compared. Twelve of the 39 SIBS-A revealed a delay in cognition and/or language (including one child diagnosed with autism) compared to only two SIBS-TD. Developmental trajectories revealed that the cognitive differences disappeared by age 54 months, but some differences in language ability remained. Thus, most SIBS-A were well-functioning, but some revealed cognitive and/or language difficulties during the preschool years. Even these siblings by and large caught up by the age of 54 months, with receptive and expressive language abilities remaining an area of difficulty for some earlier identified siblings.

Language Problems Among Abused and Neglected Children: A Meta-Analytic Review.
Sylvestre, Audette; Bussières, Ève-Line; Bouchard, Caroline
2016-02-01
Research data show that exposure to abuse and neglect has detrimental effects on a child's language development. In this meta-analysis, we analyze studies (k = 23), to compare the language skills (receptive language, expressive language, pragmatics) of children who have experienced abuse and/or neglect with the language skills of children who have not experienced abuse and/or neglect and to examine whether age or type of maltreatment moderate the relationship between maltreatment and language skills. Results confirm that the language skills of children who have experienced abuse and/or neglect are delayed when compared to children who have not experienced abuse and/or neglect. Compared to older children, young children seem particularly vulnerable to abuse and neglect. No significant differences were demonstrated concerning the type of maltreatment suffered by the child. These findings support the necessity of early detection of language problems in abused and neglected children as well as early intervention in order to implement interventions that will positively stimulate their development. © The Author(s) 2015.

The purpose of this study was to develop a practical mean for clinical evaluation of early pediatric language development by establishing developmental trajectories for receptive and expressive vocabulary growth in children between 6 and 32 months of age using a simple, time-efficient assessment tool. Simplified short form versions of the Words and Gestures and Words and Sentences vocabulary inventories in the Mandarin Communicative Development Inventory [1] were developed and used to assess early language development in developmentally normal children from 6 to 32 months of age during routine health checks. Developmental trajectories characterizing the rate of receptive and expressive vocabulary growth between 6 and 32 months of age are reported. These trajectories allow the equivalent age corresponding to a score to be determined after a brief structured interview with the child's parents that can be conducted in a busy clinical setting. The simplified short forms of the Mandarin Communicative Development Inventories can serve as a clinically useful tool to assess early child language development, providing a practical mean of objectively assessing early language development following early interventions to treat young children with hearing impairment as well as speech and language delays. Objective evidence of language development is essential for achievement of effective (re)habilitation outcomes. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

2016-01-01
The aim of this work was to evaluate receptive and expressive language skills in children with congenital hypothyroidism receiving early hormonal replacement treatment before the age of 3 months and to identify any subtle areas of weaknesses in their language development to check the necessity for future language intervention. The study was conducted on 30 hypothyroid children receiving hormonal replacement. They were subdivided into group I (5-8 years 11 months; 12 cases) and group II (9-12 years 11 months; 18 cases). All patients were subjected to a protocol of assessment applied in the Diabetes, Endocrine and Metabolism Pediatric Unit (DEMPU) and evaluation of language skills by the REAL scale. The younger group reached average Arabic language scores, while the older group showed moderate language delay. Early replacement therapy supports language development in young children. However, longitudinal and follow-up studies are required to identify difficulties presenting at older ages that may affect children in the academic settings. © 2016 S. Karger AG, Basel.

2003-01-01
The chronic serous otitis media is a well known cause of fluctuant moderated conduction deafness in childhood but not well studied in Castillian speaking areas, as a cause of alterations in the acquisition of language. In the present study we evaluate the chronic serous otitis media as a cause of alterations in the development of the language in childhood. We studied the semantic development level in a group of 18 four years old children affected of chronic serous otitis media of more than one year evolution. The incidence of alterations was of 27.7%. We discuss the results obtained and we propose a management for this pathology.

Studies investigating the development of tense/aspect in children with developmental disorders have focused on production frequency and/or relied on short spontaneous speech samples. How children with developmental disorders use future forms/constructions is also unknown. The current study expands this literature by examining frequency, consistency, and productivity of past, present, and future usage, using the Speechome Recorder, which enables collection of dense, longitudinal audio-video recordings of children's speech. Samples were collected longitudinally in a child who was previously diagnosed with autism spectrum disorder, but at the time of the study exhibited only language delay [Audrey], and a typically developing child [Cleo]. While Audrey was comparable to Cleo in frequency and productivity of tense/aspect use, she was atypical in her consistency and production of an unattested future form. Examining additional measures of densely collected speech samples may reveal subtle atypicalities that are missed when relying on only few typical measures of acquisition.

Bilingualism: A Pearl to Overcome Certain Perils of Cochlear Implants
Humphries, Tom; Kushalnagar, Poorna; Mathur, Gaurav; Napoli, Donna Jo; Padden, Carol; Rathmann, Christian; Smith, Scott
2014-01-01
Cochlear implants (CI) have demonstrated success in improving young deaf children’s speech and low-level speech awareness across a range of auditory functions, but this success is highly variable, and how this success correlates to high-level language development is even more variable. Prevalence on the success rate of CI as an outcome for language development is difficult to obtain because studies vary widely in methodology and variables of interest, and because not all cochlear implant technology (which continues to evolve) is the same. Still, even if the notion of treatment failure is limited narrowly to those who gain no auditory benefit from CI in that they cannot discriminate among ambient noises, the reported treatment failure rate is high enough to call into question the current lack of consideration of alternative approaches to ensure young deaf children’s language development. Recent research has highlighted the risks of delaying language input during critical periods of brain development with concomitant consequences for cognitive and social skills. As a result, we propose that before, during, and after implantation deaf children learn a sign language along with a spoken language to ensure their maximal language development and optimal long-term developmental outcomes.

2001-12-01
There has been limited examination of the intersection between language and arithmetic in the performance of deaf students, although some previous research has shown that deaf and hearing-impaired1 students are delayed in both their language acquisition and arithmetic performance. This paper examines the performance of deaf and hearing-impaired students in South-East Queensland, Australia, in solving arithmetic word problems. It was found that the subjects' solutions of word problems confirmed trends for hearing students, but that their performance was delayed in comparison. The results confirm other studies where deaf and hearing-impaired students are delayed in their language acquisition and this impacts on their capacity to successfully undertake the resolution of word problems.

The process of language acquisition requires an individual to organize the world through a system of symbols and referents. For children with severe intellectual disabilities and language delays, the ability to link a symbol to its referent may be a difficult task. In addition to the intervention strategy, issues such as the visual complexity and iconicity of a symbol arise when deciding what to select as a medium to teach language. This study explored the ability of four pre-school age children with developmental and language delays to acquire the meanings of Blissymbols and lexigrams using an observational experiential language intervention. In production, all four of the participants demonstrated symbol-referent relationships, while in comprehension, three of the four participants demonstrated at least emerging symbol-referent relationships. Although the number of symbols learned across participants varied, there were no differences between the learning of arbitrary and comparatively iconic symbols. The participants' comprehension skills appeared to influence their performance.

Claims have been made that language-impaired children have deficits processing rapidly presented or brief sensory information. These claims, known as the 'temporal processing hypothesis', are supported by demonstrations that language-impaired children have excess backward masking (BM). One explanation for these results is that BM is developmentally delayed in these children. However, little was known about how BM normally develops. Recently, we assessed BM in normally developing 6- and 8-year-old children and adults. Results showed that BM thresholds continue to improve over a comparatively protracted period (>10 years old). We also analysed reported deficits in BM in language-impaired and younger children, in terms of a model of temporal resolution. This analysis suggests that poor processing efficiency, rather than deficits in temporal resolution, can account for these results. This 'processing efficiency hypothesis' was recently tested in our laboratory. This experiment measured BM as a function of delays between the tone and the noise in children and adults. Results supported the processing efficiency hypothesis, and suggested that reduced processing efficiency alone could account for differences between adults and children. These findings provide a new perspective on the mechanisms underlying communication disorders, and imply that remediation strategies should be directed towards improving processing efficiency, not temporal resolution.

Sentence recall is increasingly used to assess language. It is widely debated what the task is actually testing, but one rarely explored aspect is the contribution of semantics to sentence recall. The few studies that have examined the role of semantics in sentence recall have employed an 'intrusion paradigm', following Potter and Lombardi (1990), and their paradigm relies on interference errors with conclusions based on an analysis of error patterns. We have instead manipulated the semantic plausibility of whole sentences to investigate the effects of semantics on immediate and delayed sentence recall. In Study 1, adults recalled semantically plausible and implausible sentences either immediately or after distracter tasks varying in lexical retrieval demands (backward counting and picture naming). Results revealed significant effects of plausibility, delay, and a significant interaction indicating increasing reliance on semantics as the demands of the distracter tasks increased. Study 2, conducted with 6-year-old children, employed delay conditions that were modified to avoid floor effects (delay with silence and forward counting) and a similar pattern of results emerged. This novel methodology provided robust evidence showing the effectiveness of delayed recall in the assessment of semantics and the effectiveness of immediate recall in the assessment of morphosyntax. The findings from our study clarify the linguistic mechanisms involved in immediate and delayed sentence recall, with implications for the use of recall tasks in language assessment. The reader will be able to: (i) define the difference between immediate and delayed sentence recall and different types of distractors, (ii) explain the utility of immediate and delayed recall sentence recall in language assessment, (iii) discuss suitability of delayed recall for the assessment of semantics.

Duplication of 17(p11.2p11.2) in a male child with autism and severe language delay.

Duplications of 17(p11.2p11.2) have been associated with various behavioral manifestations including attention deficits, obsessive-compulsive symptoms, autistic traits, and language delay. We are conducting a genetic study of autism and are screening all cases for submicroscopic chromosomal abnormalities, in addition to standard karyotyping, and fragile X testing. Using array-based comparative genomic hybridization analysis of data from the Affymetrix GeneChip(R) Human Mapping Array set, we detected a duplication of approximately 3.3 Mb on chromosome 17p11.2 in a male child with autism and severe expressive language delay. The duplication was confirmed by measuring the copy number of genomic DNA using quantitative polymerase chain reaction. Gene expression analyses revealed increased expression of three candidate genes for the Smith-Magenis neurobehavioral phenotype, RAI1, DRG2, and RASD1, in transformed lymphocytes from Case 81A, suggesting gene dosage effects. Our results add to a growing body of evidence suggesting that duplications of 17(p11.2p11.2) result in language delay as well as autism and related phenotypes. As Smith-Magenis syndrome is also associated with language delay, a gene involved in acquisition of language may lie within this interval. Whether a parent of origin effect, gender of the case, the presence of allelic variation, or changes in expression of genes outside the breakpoints influence the resultant phenotype remains to be determined.

The goal of the present study was to examine if internationally adopted (IA) children from China (M = 10;8) adopted by French-speaking families exhibit lags in verbal memory in addition to lags in verbal abilities documented in previous studies (Gauthier & Genesee, 2011). Tests assessing verbal and non-verbal memory, language, non-verbal cognitive ability, and socio-emotional development were administered to thirty adoptees. Their results were compared to those of thirty non-adopted monolingual French-speaking children matched on age, gender, and socioeconomic status. The IA children scored significantly lower than the controls on language, verbal short-term memory, verbal working memory, and verbal long-term memory. No group differences were found on non-verbal memory, non-verbal cognitive ability, and socio-emotional development, suggesting language-specific difficulties. Despite extended exposure to French, adoptees may experience language difficulties due to limitations in verbal memory, possibly as a result of their delayed exposure to that language and/or attrition of the birth language.

Canonical babbling (CB) is critical in forming foundations for speech. Research has shown that the emergence of CB precedes first words, predicts language outcomes, and is delayed in infants with several communicative disorders. We seek a naturalistic portrayal of CB development, using all-day home recordings to evaluate the influences of age, language, and social circumstances on infant CB production. Thus we address the nature of very early language foundations and how they can be modulated. This is the first study to evaluate possible interactions of language and social circumstance in the development of babbling. We examined the effects of age (6 and 11 months), language/culture (English and Chinese), and social circumstances (during infant-directed speech [IDS], during infant overhearing of adult-directed speech [ADS], or when infants were alone) on canonical babbling ratios (CBR = canonical syllables/total syllables). The results showed a three-way interaction of infant age by infant language/culture by social circumstance. The complexity of the results forces us to recognize that a variety of factors can interact in the development of foundations for language, and that both the infant vocal response to the language/culture environment and the language/culture environment of the infant may change across age.

Theory of mind and specific language impairment in school-age children.
Spanoudis, George
2016-01-01
Research on the relationship between aspects of language development and Theory of Mind (ToM) in children with language impairments suggests that children with language impairment show a delay in ToM development. This study aimed to examine the relationships of the syntactic, semantic, and pragmatic skills with ToM in school-age children. Twenty children with Specific Language Impairment (SLI) aged 9-12 years and two control groups, one matched for chronological age (CA) and one for language ability (LA) (aged 8-10 years) were compared on a set of language tasks tapping syntactic, semantic, and pragmatic skills and on an advanced test of ToM. Results showed that children with SLI performed poorly on the ToM task compared to the CA matches. Also, analysis showed that language skills and ToM are related and that syntactic and pragmatic abilities contributed significantly to the prediction of ToM performance in the SLI group. It is concluded that the syntax/pragmatic aspects of the language impact on ToM understanding in children with SLI. Copyright © 2016 Elsevier Inc. All rights reserved.

Children with IRS were divided into two groups according to the type of treatment in early infancy: 38 were treated with NPI (more severe cases) and 24 with postural treatment (less severe cases). Regarding interventions, children were assessed at 2 to 6 years of age using the Denver II Developmental Screening Test (Denver II) and Neurological Evolutionary Examination (NEE). According to Denver II, 73.7% in the NPI group and 79.2% in the postural group presented normal development. This result was similar to the results of different studies in the literature with typical population. Considering all areas of development, there were no significant differences in Denver II between the NPI and postural groups (P = .854). In the NPI group, 89.5% of children and 87.5% in the postural group presented normal development in NEE. Language was the most affected area, as 18.4% and 20.8% of children in NPI and postural group, respectively, presented risk for delay in the Denver II. The increased risk for delay in language area was probably due to anatomical conditions of the muscles involved in speech, and to hearing oscillations, as 47.4% in NPI group and 58.3% in postural group underwent myringotomy. IRS treated with NPI had neurological development similar to those in less severe cases. Children treated exclusively with NPI did not present delay in neurological development.

Increasing the odds: applying emergentist theory in language intervention.
Poll, Gerard H
2011-10-01
This review introduces emergentism, which is a leading theory of language development that states that language ability is the product of interactions between the child's language environment and his or her learning capabilities. The review suggests ways in which emergentism provides a theoretical rationale for interventions that are designed to address developmental language delays in young children. A review of selected literature on emergentist theory and research is presented, with a focus on the acquisition of early morphology and syntax. A significant method for developing and testing emergentist theory, connectionist modeling, is described. Key themes from both connectionist and behavioral studies are summarized and applied with specific examples to language intervention techniques. A case study is presented to integrate elements of emergentism with language intervention. Evaluating the theoretical foundation for language interventions is an important step in evidence-based practice. This article introduces three themes in the emergentist literature that have implications for language intervention: (a) sufficiency of language input, (b) active engagement of the child with the input, and (c) factors that increase the odds for correctly mapping language form to meaning. Evidence supporting the importance of these factors in effective language intervention is presented, along with limitations in that evidence.

Do Adults Show an Effect of Delayed First Language Acquisition When Calculating Scalar Implicatures?
Davidson, Kathryn; Mayberry, Rachel I
Language acquisition involves learning not only grammatical rules and a lexicon, but also what someone is intending to convey with their utterance: the semantic/pragmatic component of language. In this paper we separate the contributions of linguistic development and cognitive maturity to the acquisition of the semantic/pragmatic component of language by comparing deaf adults who had either early or late first exposure to their first language (ASL). We focus on the particular type of meaning at the semantic/pragmatic interface called scalar implicature , for which preschool-age children typically differ from adults. Children's behavior has been attributed to either their not knowing appropriate linguistic alternatives to consider or to cognitive developmental differences between children and adults. Unlike children, deaf adults with late language exposure are cognitively mature, although they never fully acquire some complex linguistic structures, and thus serve as a test for the role of language in such interpretations. Our results indicate an overall high performance by late learners, especially when implicatures are not based on conventionalized items. However, compared to early language learners, late language learners compute fewer implicatures when conventionalized linguistic alternatives are involved (e.g.

Concurrent Relations between Face Scanning and Language: A Cross-Syndrome Infant Study
D’Souza, Dean; D’Souza, Hana; Johnson, Mark H.; Karmiloff-Smith, Annette
2015-01-01
Typically developing (TD) infants enhance their learning of spoken language by observing speakers’ mouth movements. Given the fact that word learning is seriously delayed in most children with neurodevelopmental disorders, we hypothesized that this delay partly results from differences in visual face scanning, e.g., focusing attention away from the mouth. To test this hypothesis, we used an eye tracker to measure visual attention in 95 infants and toddlers with Down syndrome (DS), fragile X syndrome (FXS), and Williams syndrome (WS), and compared their data to 25 chronological- and mental-age matched 16-month-old TD controls. We presented participants with two talking faces (one on each side of the screen) and a sound (/ga/). One face (the congruent face) mouthed the syllable that the participants could hear (i.e., /ga/), while the other face (the incongruent face) mouthed a different syllable (/ba/) from the one they could hear. As expected, we found that TD children with a relatively large vocabulary made more fixations to the mouth region of the incongruent face than elsewhere. However, toddlers with FXS or WS who had a relatively large receptive vocabulary made more fixations to the eyes (rather than the mouth) of the incongruent face. In DS, by contrast, fixations to the speaker’s overall face (rather than to her eyes or mouth) predicted vocabulary size. These findings suggest that, at some point in development, different processes or strategies relating to visual attention are involved in language acquisition in DS, FXS, and WS. This knowledge may help further explain why language is delayed in children with neurodevelopmental disorders. It also raises the possibility that syndrome-specific interventions should include an early focus on efficient face-scanning behaviour. PMID:26426329

[Language acquisition in preterm infants during the first year of life].
Nazzi, T; Nishibayashi, L L; Berdasco-Muñoz, E; Baud, O; Biran, V; Gonzalez-Gomez, N
2015-10-01
Previous studies have shown that preterm children are at a higher risk for cognitive and language delays than full-term children. Most of these studies have concentrated on the effects of prematurity during the preschool or school years, while the effect of preterm birth on the early development of language, much of which occurs during the first year of life, remains very little explored. This article focuses on this crucial period and reviews the studies that have explored early phonological and lexical development in preterm infants. The results of these studies show uneven proficiency in different language subdomains in preterm infants. This raises the possibility that different constraints apply to the acquisition of different linguistic subcomponents in this population, in part as a result of a complex interaction between maturation, experience, and language subdomains.

The Bayley Scales of Infant and Toddler Development - 3rd Edition (Bayley-III) was updated to enhance its usefulness for contemporary child developmental assessment. However, recent data in Western countries have implicated the overestimation of child development by the new instrument. This study aimed to investigate the psychometric features of the Bayley-III for term and preterm infants in Taiwan. Forty-seven term infants and 167 preterm infants were prospectively examined with the Bayley Scales of Infant Development - 2nd Edition (BSID-II) and the Bayley-III at 6, 12, 18, and 24 months of age (corrected for prematurity). The psychometric properties examined included reliability, construct validity, and known-group validity. The intra- and inter-rater reliabilities of the Bayley-III were good to excellent. The correlations between the BSID-II and Bayley-III raw scores were good to excellent for the cognitive and motor items and low to excellent for the language items. Term infants achieved higher composite scores than preterm infants on all of the Bayley-III scales (p<0.05). However, their rates of developmental delay were lower than the previously established prevalence estimates. The Bayley-III cut-off composite score was adjusted 10-20, 1-13, and 12-24 points higher than 70 for optimal prediction of cognitive, language, and motor delay, respectively, as defined by the BSID-II index score<70. The Bayley-III is a reliable instrument that extends its previous edition, especially in early language assessment. However, the upward adjustment of its cut-off score is recommended for the accurate identification of developmental delay in term and preterm Taiwanese infants. Copyright © 2013 Elsevier Ltd.

Acquisition of regular inflectional suffixes is an integral part of grammatical development in English and delayed acquisition of certain inflectional suffixes is a hallmark of language impairment. We investigate the relationship between input frequency and grammatical suffix acquisition, analyzing 217 transcripts of mother-child (ages 1 ; 11-6 ; 9) conversations from the CHILDES database. Maternal suffix frequency correlates with previously reported rank orders of acquisition and with child suffix frequency. Percentages of children using a suffix are consistent with frequencies in caregiver speech. Although late talkers acquire suffixes later than typically developing children, order of acquisition is similar across populations. Furthermore, the third person singular and past tense verb suffixes, weaknesses for children with language impairment, are less frequent in caregiver speech than the plural noun suffix, a relative strength in language impairment. Similar findings hold across typical, SLI and late talker populations, suggesting that frequency plays a role in suffix acquisition.

Pre-linguistic communication skill development in an infant with a diagnosis of galactosaemia.
Lewis, Fiona M; Coman, David J; Kilcoyne, Sarah; Murdoch, Bruce E; Syrmis, Maryanne
2014-10-01
Neonatal screening for galactosaemia (GAL) identifies the condition early, but subsequent biomedical and genetic testing fails to identify which subgroup of infants with GAL are at most risk of the language disorders associated with the condition. This study aims to present preliminary data on an infant with GAL based on assessment of pre-linguistic communication behaviours known to underpin language development. This single case-control study profiles the pre-linguistic skills of a 13-month-old infant with GAL. The Index Infant's performance was descriptively compared to that of a typically developing, suitably matched control infant. The Index Infant was identified as presenting with clinically significant delays on 9 of the 11 pre-linguistic skills assessed. The early identification of risk of developmental language difficulties in the Index Infant allows for the implementation of early intervention using the infant's parents as facilitators of language stimulation. Monitoring of the infant's progress is warranted.

Language delay is considered a frequent antecedent of literacy problems and both may be linked to phonological impairment. However, while several studies have examined the relationship between language delay and reading impairment, relatively few have focused on spelling. In this study, spelling performance of 28 children with developmental dyslexia (DD), 14 children with a history of language delay (LD), and 14 children without (NoLD) and 28 control participants were examined. Spelling was investigated by a writing to dictation task that included orthographically regular stimuli (word and non-words), as well as words with unpredictable transcription. Results indicated that all dyslexic participants underperformed compared to controls on both regular and unpredictable transcription stimuli, but LD performance was generally the worst. Moreover, spelling impairment assumed different characteristics in LD and NoLD children. LD children were more sensitive to acoustic-to-phonological variables, showing relevant failure especially on stimuli containing geminate consonants but also on polysyllabic stimuli and those containing non-continuant consonants. Error analysis confirmed these results, with LD children producing a higher rate of phonological errors respect to NoLD children and controls. Results were coherent with the hypothesis that among dyslexic children, those with previous language delay have more severe spelling deficit, suffering from defective orthographic lexical acquisition together with long-lasting phonological difficulties.

Specific language impairment (SLI) is usually defined as a developmental language disorder which does not result from a hearing loss, autism, neurological and emotional difficulties, severe social deprivation, low non-verbal abilities. Children affected with SLI typically have difficulties with the acquisition of different aspects of language and by definition, their impairment is specific to language and no other skills are affected. However, there has been a growing body of literature to suggest that children with SLI also have non-linguistic deficits, including impaired motor abilities. The aim of the current study is to investigate language and motor abilities of a group of thirty children with SLI (aged between 4 and 7) in comparison to a group of 30 typically developing children matched for chronological age. The results showed that the group of children with SLI had significantly more difficulties on the language and motor assessments compared to the control group. The SLI group also showed delayed onset in the development of all motor skills under investigation in comparison to the typically developing group. More interestingly, the two groups differed with respect to which language abilities were correlated with motor abilities, however Imitation of Complex Movements was the unique skill which reliably predicted expressive vocabulary in both typically developing children and in children with SLI.

Researchers have suggested that as children’s language skill develops in early childhood, it comes to help children regulate their emotions (Cole, Armstrong, & Pemberton, 2010; Kopp, 1989), but the pathways by which this occurs have not been studied empirically. In a longitudinal study of 120 children from 18 to 48 months of age, associations among child language skill, observed anger expression, and regulatory strategies during a delay task were examined. Toddlers with better language skill, and whose language skill increased more over time, appeared less angry at 48 months and their anger declined more over time. Two regulatory strategies, support-seeking and distraction, explained a portion of the variance in the association between language skill and anger expression by 36 months. PMID:23278601

A continuum of phenotypes makes up the autism spectrum (AS). In particular, individuals show large differences in language acquisition, ranging from precocious speech to severe speech onset delay. However, the neurological origin of this heterogeneity remains unknown. Here, we sought to determine whether AS individuals differing in speech acquisition show different cortical responses to auditory stimulation and morphometric brain differences. Whole-brain activity following exposure to non-social sounds was investigated. Individuals in the AS were classified according to the presence or absence of Speech Onset Delay (AS-SOD and AS-NoSOD, respectively) and were compared with IQ-matched typically developing individuals (TYP). AS-NoSOD participants displayed greater task-related activity than TYP in the inferior frontal gyrus and peri-auditory middle and superior temporal gyri, which are associated with language processing. Conversely, the AS-SOD group only showed enhanced activity in the vicinity of the auditory cortex. We detected no differences in brain structure between groups. This is the first study to demonstrate the existence of differences in functional brain activity between AS individuals divided according to their pattern of speech development. These findings support the Trigger-threshold-target model and indicate that the occurrence of speech onset delay in AS individuals depends on the location of cortical functional reallocation, which favors perception in AS-SOD and language in AS-NoSOD.

Language impairment is common in autism spectrum disorders (ASD) and is often accompanied by atypical neural lateralization. However, it is unclear when in development language impairment or atypical lateralization first emerges. To address these questions, we recorded event-related-potentials (ERPs) to native and non-native speech contrasts longitudinally in infants at risk for ASD (HRA) over the first year of life to determine whether atypical lateralization is present as an endophenotype early in development and whether these infants show delay in a very basic precursor of language acquisition: phonemic perceptual narrowing. ERP response for the HRA group to a non-native speech contrast revealed a trajectory of perceptual narrowing similar to a group of low-risk controls (LRC), suggesting that phonemic perceptual narrowing does not appear to be delayed in these high-risk infants. In contrast there were significant group differences in the development of lateralized ERP response to speech: between 6 and 12 months the LRC group displayed a lateralized response to the speech sounds, while the HRA group failed to display this pattern. We suggest the possibility that atypical lateralization to speech may be an ASD endophenotype over the first year of life. Copyright © 2012 Elsevier Ltd. All rights reserved.

2014-06-01
We examined early speech and language development in children who had cerebral palsy. Questions addressed whether children could be classified into early profile groups on the basis of speech and language skills and whether there were differences on selected speech and language measures among groups. Speech and language assessments were completed on 27 children with CP who were between the ages of 24 and 30 months (mean age 27.1 months; SD 1.8). We examined several measures of expressive and receptive language, along with speech intelligibility. Two-step cluster analysis was used to identify homogeneous groups of children based on their performance on the seven dependent variables characterizing speech and language performance. Three groups of children identified were those not yet talking (44% of the sample); those whose talking abilities appeared to be emerging (41% of the sample); and those who were established talkers (15% of the sample). Group differences were evident on all variables except receptive language skills. 85% of 2-year-old children with CP in this study had clinical speech and/or language delays relative to age expectations. Findings suggest that children with CP should receive speech and language assessment and treatment at or before 2 years of age.

The 15q11.2 BP1-BP2 region is found duplicated or deleted in people with cognitive, language, and behavioral impairment. We report on a family (a father and 3 male twin siblings) that presents with a duplication of the 15q11.2 BP1-BP2 region and a variable phenotype: the father and the fraternal twin are normal carriers, whereas the monozygotic twins exhibit severe language and cognitive delay as well as behavioral disturbances. The genes located within the duplicated region are involved in brain development and function, and some of them are related to language processing. The probands' phenotype may result from changes in the expression level of some of these genes important for cognitive development. PMID:28588435

Functional near infrared spectroscopy (fNIRS) is a non-invasive functional neuroimaging modality. Although, it is amenable to use in infants and young children, there is a lack of fNIRS research within the toddler age range. In this study, we used fNIRS to measure cerebral hemodynamics in the prefrontal cortex (PFC) in 18–36 months old toddlers (n = 29) as part of a longitudinal study that enrolled typically-developing toddlers as well as those “at risk” for language and other delays based on presence of early language delays. In these toddlers, we explored two hemodynamic response indices during periods of rest during which time audiovisual children's programming was presented. First, we investigate Lateralization Index, based on differences in oxy-hemoglobin saturation from left and right prefrontal cortex. Then, we measure oxygenation variability (OV) index, based on variability in oxygen saturation at frequencies attributed to cerebral autoregulation. Preliminary findings show that lower cognitive (including language) abilities are associated with fNIRS measures of both lower OV index and more extreme Lateralization index values. These preliminary findings show the feasibility of using fNIRS in toddlers, including those at risk for developmental delay, and lay the groundwork for future studies. PMID:28611578

Nonverbal imitation skills in children with specific language delay.
Dohmen, Andrea; Chiat, Shula; Roy, Penny
2013-10-01
Research in children with language problems has focussed on verbal deficits, and we have less understanding of children's deficits with nonverbal sociocognitive skills which have been proposed to be important for language acquisition. This study was designed to investigate elicited nonverbal imitation in children with specific language delay (SLD). It is argued that difficulties in nonverbal imitation, which do not involve the processing of structural aspects of language, may be indicative of sociocognitive deficits. Participants were German-speaking typically developing children (n=60) and children with SLD (n=45) aged 2-3 ½ years. A novel battery of tasks measured their ability to imitate a range of nonverbal target acts that to a greater or lesser extent involve sociocognitive skills (body movements, instrumental acts on objects, pretend acts). Significant group differences were found for all body movement and pretend act tasks, but not for the instrumental act tasks. The poorer imitative performance of the SLD sample was not explained by motor or nonverbal cognitive skills. Thus, it appeared that the nature of the task affected children's imitation performance. It is argued that the ability to establish a sense of connectedness with the demonstrator was at the core of children's imitation difficulty in the SLD sample. Copyright © 2013 Elsevier Ltd.

The objective of this study was to determine the risk factors for and relationship among parasitic infections, growth retardation, and psychomotor developmental delays in children aged 6 years and below. This case-control study was performed in Şanlıurfa in southeastern Turkey between October and December 2007. Data were collected using a structured questionnaire, anthropometry, Ankara Development Screening Inventory, and laboratory analysis of stool specimens. The most common parasite was Giardia intestinalis (42.53%) followed by Enterobius vermicularis (27.58%), Ascaris lumbricoides (18.39%), Hymenolepis nana (5.75%), Trichuris trichiura (3.45%), Escherichia coli (1.15%), and Blastocystis spp. (1.15%). Fifty-eight percent of all children were infected with intestinal parasites; 55.2% had only one parasite, whereas 44.8% had multiple parasites. The children infected with G. intestinalis and other intestinal parasites had significantly higher levels of growth retardation and psychomotor development delay than non-infected children. Children with parasitic infections had growth delay up to 2.9 times, general development delay up to 1.9 times, language-cognitive development delay up to 2.2 times, and fine motor development delay up to 2.9 times higher than children without any parasitic infections. However, no significant relationship among intestinal parasites, gross motor development, social-self skills, and development delay was identified. The education level of parents, poor economic situation, number of households, not washing hands, playing with soil, family history of parasitic infection were the significant risk factors for intestinal parasites. Our study indicates that the presence of either malnutrition or intestinal parasites may put a child in a high-risk group for developmental delays and growth retardation. Therefore, public health interventions can embrace nationwide deworming in children.

OBJECTIVE: The aim of this research was to compare language development (expressive and receptive skills) in children awaiting liver transplantation with that of children who have already undergone the surgical procedure. METHODS: An observational, descriptive, cross-sectional study was conducted with 76 children divided into groups, as follows: 31 children who were candidates for liver transplantation (Group 1; G1), 45 children who had already undergone liver transplantation (Group 2; G2), and a control group (CG) of 60 healthy, normally developing children. Health status information was gathered, and the Test of Early Language Development (TELD)-3 was used to assess language skills. Family household monthly income data were also gathered using a specific questionnaire. RESULTS: G1 had poorer language performance compared with G2 and the CG. G2 had lower language performance when compared with the CG. However, when considering the TELD-3 standard scores, G2 had scores within normal limits. The regression analysis indicated age as a risk factor for language deficits in Group 1 and family income as a risk factor for language deficits in G2. CONCLUSIONS: The results suggested that children with chronic liver disease have delays in language development. Transplanted children have linguistic performance within normal limits, but their scores tended to be lower than the CG. PMID:28658434

Children with pre/perinatal unilateral brain lesions (PL) show remarkable plasticity for language development. Is this plasticity characterized by the same developmental trajectory that characterizes typically developing (TD) children, with gesture leading the way into speech? We explored this question, comparing 11 children with PL—matched to 30 TD children on expressive vocabulary—in the second year of life. Children with PL showed similarities to TD children for simple but not complex sentence types. Children with PL produced simple sentences across gesture and speech several months before producing them entirely in speech, exhibiting parallel delays in both gesture+speech and speech-alone. However, unlike TD children, children with PL produced complex sentence types first in speech-alone. Overall, the gesture-speech system appears to be a robust feature of language-learning for simple—but not complex—sentence constructions, acting as a harbinger of change in language development even when that language is developing in an injured brain.

To evaluate the neurodevelopmental outcomes of preterm very-low birth weight (PT/VLBW) infants at 2 years and identify risk factors associated with significant developmental delay or neurodevelopmental impairment (NDI). We evaluated 165 PT/VLBW infants born between January 2010 and December 2011, using the Bayley Scales of Infant and Toddler Development 3rd Edition (Bayley-III). NDI was defined as the presence of neurosensory impairment or significant delay with Bayley-III score < 70 in any domain and risk factors for delay/NDI were assessed using logistic regressions. Median Bayley-III composite scores in the cognitive, language and motor domains were 95, 89 and 94, respectively. NDI was present in 20% of the children, with 5-18% having significant delay in either cognitive, language or motor domain, seven (4%) children had cerebral palsy, three (2%) were deaf and none were blind. Regression models identified significant positive associations of delayed cognitive skills with male gender (Odds ratio (OR) 22.4, 95% confidence interval (CI) 1.5-341.1; P = 0.025), lack of anntenatal steroids (ANS) (OR 41.5, 95% CI 3.5-485.7; P = 0.003), and hypotension needing inotropes (OR 36.0, 95% CI 2.6-506.0; P = 0.008); delayed language skills with lower maternal education (OR 3.8, 95% CI 1.4-10.3; P = 0.10), lack of ANS (OR 2.8, 95% CI 1.1-7.4; P = 0.04), and 5 minute Apgar Score ≤ 5 (OR 7.4, 95% CI 1.4-38.4; P = 0.017) and delayed motor skills with chronic lung disease at 36 weeks (OR 38.3, 95% CI 2.4-603.4; P = 0.010). NDI was associated with lack of ANS (OR 2.91, 95% CI 1.21-7.00; P = 0.02) and use of postnatal steroids (OR 3.36, 95% CI 1.07-10.54; P = 0.0374). Risk factors for both NDI and individual domain delay were identified and will be helpful in planning of specific and targeted early intervention services.

The effect of sign language structure on complex word reading in Chinese deaf adolescents.
Lu, Aitao; Yu, Yanping; Niu, Jiaxin; Zhang, John X
2015-01-01
The present study was carried out to investigate whether sign language structure plays a role in the processing of complex words (i.e., derivational and compound words), in particular, the delay of complex word reading in deaf adolescents. Chinese deaf adolescents were found to respond faster to derivational words than to compound words for one-sign-structure words, but showed comparable performance for two-sign-structure words. For both derivational and compound words, response latencies to one-sign-structure words were shorter than to two-sign-structure words. These results provide strong evidence that the structure of sign language affects written word processing in Chinese. Additionally, differences between derivational and compound words in the one-sign-structure condition indicate that Chinese deaf adolescents acquire print morphological awareness. The results also showed that delayed word reading was found in derivational words with two signs (DW-2), compound words with one sign (CW-1), and compound words with two signs (CW-2), but not in derivational words with one sign (DW-1), with the delay being maximum in DW-2, medium in CW-2, and minimum in CW-1, suggesting that the structure of sign language has an impact on the delayed processing of Chinese written words in deaf adolescents. These results provide insight into the mechanisms about how sign language structure affects written word processing and its delayed processing relative to their hearing peers of the same age.

Learning problems, delayed development, and puberty
Wright, Beverly A.; Zecker, Steven G.
2004-01-01
Language-based learning disorders such as dyslexia affect millions of people, but there is little agreement as to their cause. New evidence from behavioral measures of the ability to hear tones in the presence of background noise indicates that the brains of affected individuals develop more slowly than those of their unaffected counterparts. In addition, it seems that brain changes occurring at ≈10 years of age, presumably associated with puberty, may prematurely halt this slower-than-normal development when improvements would normally continue into adolescence. The combination of these ideas can account for a wide range of previous results, suggesting that delayed brain development, and its interaction with puberty, may be key factors contributing to learning problems.

Severity of specific language impairment predicts delayed development in number skills
Durkin, Kevin; Mok, Pearl L. H.; Conti-Ramsden, Gina
2013-01-01
The extent to which mathematical development is dependent upon language is controversial. This longitudinal study investigates the role of language ability in children's development of number skills. Participants were 229 children with specific language impairment (SLI) who were assessed initially at age 7 and again 1 year later. All participants completed measures of psycholinguistic development (expressive and receptive), performance IQ, and the Basic Number Skills subtest of the British Ability Scales. Number skills data for this sample were compared with normative population data. Consistent with predictions that language impairment would impact on numerical development, average standard scores were more than 1 SD below the population mean at both ages. Although the children showed improvements in raw scores at the second wave of the study, the discrepancy between their scores and the population data nonetheless increased over time. Regression analyses showed that, after controlling for the effect of PIQ, language skills explained an additional 19 and 17% of the variance in number skills for ages 7 and 8, respectively. Furthermore, logistic regression analyses revealed that less improvement in the child's language ability over the course of the year was associated with a greater odds of a drop in performance in basic number skills from 7 to 8 years. The results are discussed in relation to the interaction of linguistic and cognitive factors in numerical development and the implications for mathematical education. PMID:24027548

Impairments in language and communication are an early-appearing feature of autism spectrum disorders (ASD), with delays in language and gesture evident as early as the first year of life. Research with typically developing populations highlights the importance of both infant and maternal gesture use in infants’ early language development. The current study explores the gesture production of infants at risk for autism and their mothers at 12 months of age, and the association between these early maternal and infant gestures and between these early gestures and infants’ language at 18 months. Gestures were scored from both a caregiver-infant interaction (both infants and mothers) and from a semi-structured task (infants only). Mothers of non-diagnosed high risk infant siblings gestured more frequently than mothers of low risk infants. Infant and maternal gesture use at 12 months was associated with infants’ language scores at 18 months in both low risk and non-diagnosed high risk infants. These results demonstrate the impact of risk status on maternal behavior and the importance of considering the role of social and contextual factors on the language development of infants at risk for autism. Results from the subset of infants who meet preliminary criteria for ASD are also discussed. PMID:23585026

The present study investigated the role of early stimulation in the home and child language delays in the emergence of depressive symptoms. Data were from a longitudinal study of at-risk children in Hawaii (n = 587). Low learning stimulation in the home at age 3 and language delays in first grade both significantly increased risk for child depressive symptoms in third grade. Structural equation modeling supported the hypothesized path models from home learning environment at age 3 to depressive symptoms in third grade controlling for a host of correlated constructs (maternal depression, child temperament, and child internalizing symptoms). Total language skills in the first grade mediated the effect of home learning environment on depressive symptoms. The study and findings fit well with a nurturing environment perspective. Implications for understanding the etiology of child depression and for designing interventions and prevention strategies are discussed.

Deception is a controversial aspect of theory of mind, and researchers disagree about whether it entails an understanding of the false beliefs of one's opponent. The present study asks whether children with delayed language and delayed explicit false belief reasoning can succeed on explicit deception tasks. Participants were 45 orally taught deaf children with varying language delays aged 4.5-8 years and 45 hearing children aged 3.5-6 years. Participants received a battery of language, executive function, deception, and both verbal and low-verbal false belief tasks. The result reveal a dissociation of deception and false belief tasks: the deaf children are on par with their hearing peers on deception games, but show significant delays in false belief tasks even when the language demands are made minimal. Furthermore, different skills are predictors of success for the two types of task in the deaf children: language, and in particular complement syntax, is the best predictor of false belief reasoning; but executive function skills, especially inhibitory control, are the best predictors of deception. It is argued that deception at this level can be handled by behaviour rules without reference to mental states. © 2011 The British Psychological Society.

Within the primary motor cortex, navigated transcranial magnetic stimulation (nTMS) has been shown to yield maps strongly correlated with those generated by direct cortical stimulation (DCS). However, the stimulation parameters for repetitive nTMS (rTMS)-based language mapping are still being refined. For this purpose, the present study compares two rTMS protocols, which differ in the timing of pulse train onset relative to picture presentation onset during object naming. Results were the correlated with DCS language mapping during awake surgery. Thirty-two patients with left-sided perisylvian tumors were examined by rTMS prior to awake surgery. Twenty patients underwent rTMS pulse trains starting at 300 ms after picture presentation onset (delayed TMS), whereas another 12 patients received rTMS pulse trains starting at the picture presentation onset (ONSET TMS). These rTMS results were then evaluated for correlation with intraoperative DCS results as gold standard in terms of differential consistencies in receiver operating characteristics (ROC) statistics. Logistic regression analysis by protocols and brain regions were conducted. Within and around Broca's area, there was no difference in sensitivity (onset TMS: 100%, delayed TMS: 100%), negative predictive value (NPV) (onset TMS: 100%, delayed TMS: 100%), and positive predictive value (PPV) (onset TMS: 55%, delayed TMS: 54%) between the two protocols compared to DCS. However, specificity differed significantly (onset TMS: 67%, delayed TMS: 28%). In contrast, for posterior language regions, such as supramarginal gyrus, angular gyrus, and posterior superior temporal gyrus, early pulse train onset stimulation showed greater specificity (onset TMS: 92%, delayed TMS: 20%), NPV (onset TMS: 92%, delayed TMS: 57%) and PPV (onset TMS: 75%, delayed TMS: 30%) with comparable sensitivity (onset TMS: 75%, delayed TMS: 70%). Logistic regression analysis also confirmed the greater fit of the predictions by rTMS that had the pulse train onset coincident with the picture presentation onset when compared to the delayed stimulation. Analyses of differential disruption patterns of mapped cortical regions were further able to distinguish clusters of cortical regions standardly associated with semantic and pre-vocalization phonological networks proposed in various models of word production. Repetitive nTMS predictions by both protocols correlate well with DCS outcomes especially in Broca's region, particularly with regard to TMS negative predictions. With this study, we have demonstrated that rTMS stimulation onset coincident with picture presentation onset improves the accuracy of preoperative language maps, particularly within posterior language areas. Moreover, immediate and delayed pulse train onsets may have complementary disruption patterns that could differentially capture cortical regions causally necessary for semantic and pre-vocalization phonological networks.

The purpose of this study is to determine the impact of repetitive transcranial stimulation (rTMS) treatment during pregnancy on neurodevelopment of children. Women who were treated with rTMS during pregnancy and delivered liveborn children between 2008 and 2013 were selected. A control group consisted of children whose mothers had a history of untreated depression during their pregnancy (N = 26). Early developmental characteristics of all the children in the study were evaluated, and their developmental levels were determined using the Ankara Developmental Screening Inventory. The mean age of the children in the rTMS treatment group was 32.4 months (range 16-64 months), and that of the untreated group was 29.04 (range 14-63 months). Jaundice (N = 2) and febrile convulsion (N = 1) were the reported medical conditions in the children of the rTMS-treated group; jaundice (N = 3) and low birth weight (N = 1) were reported in the untreated group. In the rTMS group, mothers' perception of delay in language development was observed, but there were not any statistically significant differences in the prevalence rate compared with the untreated group (OR = 0.38; 95% CI 0.0860-1.6580). Our results suggest that rTMS exposure during pregnancy is not associated with poorer cognitive or motor development outcomes in children aged 18-62 months. Although language development as reported by the mothers was found to be poorer than expected in the rTMS-treated group, the delay was found to be similar to the language delay observed in offspring of untreated mothers, as reported in previous studies of prenatal depression treated with selective serotonin reuptake inhibitors. © 2014 International Neuromodulation Society.

Young children with autism spectrum disorder (ASD) often demonstrate delays in expressive communication, impacting their ability to independently function in typical environments. Individuals with ASD who develop expressive language during early childhood experience better outcomes later in life; therefore, examination of naturalistic language interventions (NLIs) remain an important area of investigation. The current study used a multiple probe design across participants to examine the effects of a classroom-based NLI on various expressive language targets in three preschool-aged children demonstrating characteristics of ASD. Findings suggest the intervention had positive and maintained effects on trial-based use of language targets, as well as concomitant changes in commenting, requesting, and phrase complexity. Implications regarding implementation of NLIs within typical classroom play activities are discussed.

In this article, the authors examine the developmental continuity from prelinguistic communication to kindergarten age in language and working memory capacity. Following work outlining 6 groups of children with different trajectories of early communication development (ECD; Määttä, Laakso, Tolvanen, Ahonen, & Aro, 2012), the authors examined their later development by psychometric assessment. Ninety-one children first assessed at ages 12-21 months completed a battery of language and working memory tests at age 5;3 (years;months). Two of the ECD groups previously identified as being at risk for language difficulties continued to show weaker performance at follow-up. Seventy-nine percent of the children with compromised language skills at follow-up were identified on the basis of the ECD groups, but the number of false positives was high. The 2 at-risk groups also differed significantly from the typically developing groups in the measures tapping working memory capacity. In line with the dimensional view of language impairment, the accumulation of early delays predicted the amount of later difficulties; however, at the individual level, the prediction had rather low specificity. The results imply a strong link between language and working memory and call for further studies examining the early developmental interaction between language and memory.

Large variability in individual spoken language outcomes remains a persistent finding in the group of children with cochlear implants (CIs), particularly in their grammatical development. In the present study, we examined the extent of delay in lexical and morphosyntactic spoken language levels of children with CIs as compared to those of a normative sample of age-matched children with normal hearing. Furthermore, the predictive value of auditory and verbal memory factors in the spoken language performance of implanted children was analyzed. Thirty-nine profoundly deaf children with CIs were assessed using a test battery including measures of lexical, grammatical, auditory and verbal memory tests. Furthermore, child-related demographic characteristics were taken into account. The majority of the children with CIs did not reach age-equivalent lexical and morphosyntactic language skills. Multiple linear regression analyses revealed that lexical spoken language performance in children with CIs was best predicted by age at testing, phoneme perception, and auditory word closure. The morphosyntactic language outcomes of the CI group were best predicted by lexicon, auditory word closure, and auditory memory for words. Qualitatively good speech perception skills appear to be crucial for lexical and grammatical development in children with CIs. Furthermore, strongly developed vocabulary skills and verbal memory abilities predict morphosyntactic language skills. Copyright © 2016 Elsevier Ltd. All rights reserved.

Why is number word learning hard? Evidence from bilingual learners.
Wagner, Katie; Kimura, Katherine; Cheung, Pierina; Barner, David
2015-12-01
Young children typically take between 18 months and 2 years to learn the meanings of number words. In the present study, we investigated this developmental trajectory in bilingual preschoolers to examine the relative contributions of two factors in number word learning: (1) the construction of numerical concepts, and (2) the mapping of language specific words onto these concepts. We found that children learn the meanings of small number words (i.e., one, two, and three) independently in each language, indicating that observed delays in learning these words are attributable to difficulties in mapping words to concepts. In contrast, children generally learned to accurately count larger sets (i.e., five or greater) simultaneously in their two languages, suggesting that the difficulty in learning to count is not tied to a specific language. We also replicated previous studies that found that children learn the counting procedure before they learn its logic - i.e., that for any natural number, n, the successor of n in the count list denotes the cardinality n+1. Consistent with past studies, we found that children's knowledge of successors is first acquired incrementally. In bilinguals, we found that this knowledge exhibits item-specific transfer between languages, suggesting that the logic of the positive integers may not be stored in a language-specific format. We conclude that delays in learning the meanings of small number words are mainly due to language-specific processes of mapping words to concepts, whereas the logic and procedures of counting appear to be learned in a format that is independent of a particular language and thus transfers rapidly from one language to the other in development.

To investigate whether prenatal atazanavir (ATV) exposure, assessed by meconium antiretroviral (ARV) quantification, predicts early child language outcomes. Prenatal ATV exposure previously was associated with poorer language development in 1-year olds. Pregnant women with HIV and their uninfected infants enrolled in the Surveillance Monitoring of Antiretroviral Therapy Toxicities study. Meconium ARV concentrations were quantified by liquid chromatography-tandem mass spectrometry. Language development at 1 year was assessed with MacArthur-Bates Communicative Development Inventory (CDI) and Bayley Scales of Infant and Toddler Development-Third Edition (Bayley-III). Late language emergence was defined as ≥ 1 of 4 CDI scores ≤ 10th percentile for age. Associations between fetal ATV exposure timing and duration, meconium ATV concentration, and language outcomes were evaluated, adjusting for potential confounders. Through 2013, meconium samples were available from 175 of 432 infants with prenatal ATV exposure. Valid Bayley-III (n = 93) and CDI (n = 106) assessments also were available. After adjustment for potential confounders, higher ATV meconium concentrations were associated with lower late language emergence risk (P = 0.04) and cumulative ATV exposure duration also was associated with higher Bayley-III Language scores (P = 0.03). Maternal ATV duration and initiation week correlated with ATV meconium concentrations (positively and negatively, respectively). Higher meconium ATV concentrations were protective against developmental language delays at 1 year, suggesting the importance of fetal ATV detoxification into meconium. This information supports ATV exposure safety for infant language development. ATV is a preferred ARV for pregnant women with HIV, suggesting the importance of ATV safety investigations. Additionally, further pursuit of the influences on language development in HIV-exposed uninfected infants is required.

There is an emerging literature suggesting that speaking two or more languages may significantly delay the onset of dementia. Although the mechanisms are unknown, it has been suggested that these may involve cognitive reserve, a concept that has been associated with factors such as higher levels of education, occupational status, social networks, and physical exercise. In the case of bilingualism, cognitive reserve may involve reorganization and strengthening of neural networks that enhance executive control. We review evidence for protective effects of bilingualism from a multicultural perspective involving studies in Toronto and Montreal, Canada, and Hyderabad, India. Reports from Toronto and Hyderabad showed a significant effect of speaking two or more languages in delaying onset of Alzheimer's disease by up to 5 years, whereas the Montreal study showed a significant protective effect of speaking at least four languages and a protective effect of speaking at least two languages in immigrants. Although there were differences in results across studies, a common theme was the significant effect of language use history as one of the factors in determining the onset of Alzheimer's disease. Moreover, the Hyderabad study extended the findings to frontotemporal dementia and vascular dementia. PMID:24959001

Learning problems, delayed perceptual development, and puberty

Language-based learning problems affect approximately one person in twelve with no other obvious signs of disorder. Many of these individuals have accompanying deficits in nonlinguistic perception. To determine whether age influences the magnitude of these deficits, thresholds on a set of auditory masking tasks were measured in individuals with learning problems and controls ranging in age from 6 years to adult. Performance improved with increasing age in both groups. However, the thresholds of the individuals with learning problems were most similar to those of controls approximately 2-4 years younger on every task, suggesting that the perceptual development of the affected individuals was delayed by a constant amount. Further, on the subset of conditions on which controls reached adult levels of performance after 10 years of age, the improvement of affected individuals halted at 10 years of age, suggesting that puberty may play a critical role in human perceptual development. Taken together, these data support the idea that some learning problems result from a neuromaturational delay, of unknown breadth, and indicate that neurological changes associated with puberty prevent the complete resolution of delayed perceptual development.

Children with cleft palates often suffer from chronic conductive hearing losses, delayed language acquisition and speech disorders. This study presents results of speech and language outcomes in relation to hearing function and types of palatal malformations found. 417 children with cleft palates were examined during followup evaluations that extended over several years. Disorders were studied as they affected the ears, nose and throat, audiometry and speech and language pathology. Children with isolated cleft lips were excluded. Among the total group, 8% had normal speech and language development while 92% had speech or language disorders. 80% of these latter children had hearing problems that predominantly consisted of fluctuating conductive hearing losses caused by otitis media with effusion. 5% had sensorineural hearing losses. Fifty-eight children (14%) with rhinolalia aperta were not improved by speech therapy and required velopharyngoplasties, using a cranial-based pharyngeal flap. Language skills did not depend on the type of cleft palate presents but on the frequency and amount of hearing loss found. Otomicroscopy and audiometric follow-ups with insertions of ventilation tubes were considered to be most important for language development in those children with repeated middle ear infections. Speech or language therapy was necessary in 49% of the children.

It is generally agreed that cognitive and language development are dependent on the emergence of motor skills. As the literature on this issue concerning children with developmental disabilities is scarce, we examined the interrelationships between motor, cognitive, and language development in children with intellectual and developmental disabilities (IDD) and compared them to those in children without IDD. In addition, we investigated whether these relationships differ between children with different levels of cognitive delay. Seventy-seven children with IDD (calendar age between 1;0 and 9;10 years; mean developmental age: 1;8 years) and 130 typically developing children (calendar age between 0;3 and 3;6 years; mean developmental age: 1;10 years) were tested with the Dutch Bayley Scales of Infant and Toddler Development, Third Edition, which assesses development across three domains using five subscales: fine motor development, gross motor development (motor), cognition (cognitive), receptive communication, and expressive communication (language). Results showed that correlations between the motor, cognitive, and language domains were strong, namely .61 to .94 in children with IDD and weak to strong, namely .24 to .56 in children without IDD. Furthermore, the correlations showed a tendency to increase with the severity of IDD. It can be concluded that both fine and gross motor development are more strongly associated with cognition, and consequently language, in children with IDD than in children without IDD. The findings of this study emphasize the importance of early interventions that boost both motor and cognitive development, and suggest that such interventions will also enhance language development.

Auditory sensory memory and language abilities in former late talkers: a mismatch negativity study.
Grossheinrich, Nicola; Kademann, Stefanie; Bruder, Jennifer; Bartling, Juergen; Von Suchodoletz, Waldemar
2010-09-01
The present study investigated whether (a) a reduced duration of auditory sensory memory is found in late talking children and (b) whether deficits of sensory memory are linked to persistent difficulties in language acquisition. Former late talkers and children without delayed language development were examined at the age of 4 years and 7 months using mismatch negativity (MMN) with interstimulus intervals (ISIs) of 500 ms and 2000 ms. Additionally, short-term memory, language skills, and nonverbal intelligence were assessed. MMN mean amplitude was reduced for the ISI of 2000 ms in former late talking children both with and without persistent language deficits. In summary, our findings suggest that late talkers are characterized by a reduced duration of auditory sensory memory. However, deficits in auditory sensory memory are not sufficient for persistent language difficulties and may be compensated for by some children.

False Belief Development in Children Who Are Hard of Hearing Compared With Peers With Normal Hearing
Ambrose, Sophie E.; Oleson, Jacob; Moeller, Mary Pat
2017-01-01
Purpose This study investigates false belief (FB) understanding in children who are hard of hearing (CHH) compared with children with normal hearing (CNH) at ages 5 and 6 years and at 2nd grade. Research with this population has theoretical significance, given that the early auditory–linguistic experiences of CHH are less restricted compared with children who are deaf but not as complete as those of CNH. Method Participants included CHH and CNH who had completed FB tasks as part of a larger multicenter, longitudinal study on outcomes of children with mild-to-severe hearing loss. Both cross-sectional and longitudinal data were analyzed. Results At age 5 years, CHH demonstrated significant delays in FB understanding relative to CNH. Both hearing status and spoken-language abilities contributed to FB performance in 5-year-olds. A subgroup of CHH showed protracted delays at 6 years, suggesting that some CHH are at risk for longer term delays in FB understanding. By 2nd grade, performance on 1st- and 2nd-order FBs did not differ between CHH and CNH. Conclusions Preschool-age CHH are at risk for delays in understanding others' beliefs, which has consequences for their social interactions and pragmatic communication. Research related to FB in children with hearing loss has the potential to inform our understanding of mechanisms that support social–cognitive development, including the roles of language and conversational access.

Optimal development of children in their early months and years has a bearing on their achievement levels later in life. To assess the socio-emotional and cognitive development in children 0-5 years and to find out the proportion of children having developmental delay and its associated factors. A community-based cross-sectional study was carried out in 520 children in Delhi. Development was assessed using the Indian Council for Medical Research Development Screening Test. In all, 10.6% of children <5 years old were found to be developmentally delayed. Maximum number of children (10.1%) were found to have a delay in the do main of 'hearing language, concept development'. Of all the factors, the strongest association was found with stunting, paternal education, alcohol abuse, attendance in anganwadi/playschool. The study concludes that developmental delay is present in a sizable proportion of children <5 years of age and may be a significant factor in the overall achievement of life's potential in them. © The Author [2016].

Children with Specific Language Impairment present with delayed language development, but do not have a history of hearing impairment, mental deficiency, or associated social or behavioral problems. Non-word repetition was suggested as an index to reflect the capacity of phonological working memory. There is a paucity of such studies among Hong Kong Chinese children. This preliminary study aimed to examine the relationship between phonological working memory and Specific Language Impairment, through the processes of non-word repetition and sentence comprehension, of children with Specific Language Impairment and pre-school children with normal language development. Both groups of children were screened by a standardized language test. A list of Cantonese (the commonest dialect used in Hong Kong) multisyllabic nonsense utterances and a set of 18 sentences were developed for this study. t-tests and Pearson correlation were used to study the relationship between non-word repetition, working memory and specific language impairment. Twenty-three pre-school children with Specific Language Impairment (mean age = 68.30 months; SD = 6.90) and another 23 pre-school children (mean age = 67.30 months; SD = 6.16) participated in the study. Significant difference performance was found between the Specific Language Impairment group and normal language group in the multisyllabic nonsense utterances repetition task and the sentence comprehension task. Length effect was noted in Specific Language Impairment group children, which is consistent with the findings of other literature. In addition, correlations were also observed between the number of nonsense utterances repeated and the number of elements comprehended. Cantonese multisyllabic nonsense utterances might be worth further developing as a screening tool for the early detection of children with Specific Language Impairment.

Eighteen children (13 males, five females) who had severe developmental language delay/disorder and some features of autism (although insufficient in severity and combination to meet ICD-10 diagnostic criteria for childhood autism) at preschool age (Time 1; mean age 4 years 4 months) were followed up 4 years later (Time 2; mean age 8 years 7 months). At the initial assessment the diagnostic dilemma was how much the social communication impairments and behavioural problems were secondary to the language problem and how much they constituted a genuine case of a pervasive developmental disorder. It was anticipated that at follow-up some children would continue to show social impairments but that in others social impairments would have receded as language competence improved. Follow-up assessments included the Wechsler Intelligence Scale for Children, the Clinical Evaluation of Language Fundamentals, the Children's Communication Checklist, and the Social Communication Questionnaire. At follow-up, five children had continuing language disorder and were considered to fulfil diagnostic criteria for childhood autism, four children had continuing language disorder and met criteria for atypical autism, and nine met criteria for atypical autism but had somewhat recovered language skills. Thus, even in the subgroup of children whose language ability had improved the features of autism had not dissipated. Severity of social communication impairments and repetitive behaviours at Time 1, rated retrospectively from case notes, were associated with severity of autism symptoms and pragmatic competence at Time 2. The findings are discussed in relation to the unclear boundary between autism spectrum disorders and language delay/disorder.

Hearing impairment and language delay in infants: Diagnostics and genetics
Lang-Roth, Ruth
2014-01-01
This overview study provides information on important phoniatric and audiological aspects of early childhood hearing and language development with the aim of presenting diagnostic and therapeutic approaches. The article first addresses the universal newborn hearing screening that has been implemented in Germany for all infants since January 2009. The process of newborn hearing screening from the maternity ward to confirmation diagnostics is presented in accordance with a decision by the Federal Joint Committee (G-BA). The second topic is pediatric audiology diagnostics. Following confirmation of a permanent early childhood hearing disorder, the search for the cause plays an important role. Hereditary hearing disorders and intrauterine cytomegalovirus (CMV) infection, probably the most common cause of an acquired hearing disorder, are discussed and compared with the most common temporary hearing disorder, otitis media with effusion, which in some cases is severe enough to be relevant for hearing and language development and therefore requires treatment. The third topic covered in this article is speech and language development in the first 3 years of life, which is known today to be crucial for later language development and learning to read and write. There is a short overview and introduction to modern terminology, followed by the abnormalities and diagnostics of early speech and language development. Only some aspects of early hearing and language development are addressed here. Important areas such as the indication for a cochlear implant in the first year of life or because of unilateral deafness are not included due to their complexity. PMID:25587365

Objective The aim of this study is assessment of effects of different assisted reproductive techniques (ART) like in vitro fertilization (IVF) and intra cytoplasmic sperm injection (ICSI) on prelinguistic behavior of infants conceived by these techniques. Methods In this descriptive, cross sectional study, prelinguistic behavior of 151 full term ART infants of Royan Institute have been assessed in Children's Health and Development Research Center of Tehran from August 2007 until August 2009. Questionnaires were completed by parents at 9 months old. The questionnaire was standard according to Early Language Milestone Scale-2 (ELM-2). Data were analyzed by SPSS version 16 and using chi-square test. Findings Twenty-two (14.5%) of infants were conceived by IVF and 129 (85.4%) by ICSI. Number of infants with delay in reduplicated babbling in ICSI method was more than in IVF. There was only a significant difference in echolalia delay in the two sexes. Echolalia was delayed more in boys. Delay of reduplicated babbling was more in infants of younger mothers. There was no relation between speech and language defect of parents and infants. Conclusion This study showed that prelingustic behavior of ART infants are affected by kind of ART method, infant sex, and mother's age at the time of pregnancy. PMID:23431035

The objective of this study was to examine the impact of low birth weight and preterm birth on a toddler's inattention and development, including cognitive, language, motor, social-emotional and adaptive behaviors. A total of 105 toddlers enrolled for the study; they were divided into four groups: 40 full-term and normal birth weight (NBW, birth weight greater than 2500 g) toddlers, 24 moderate birth weight (MLBW, birth weight between 2499 and 1500 g) toddlers, 20 very to extremely low birth weight (V-ELBW, 12 between 1000 and 1499 g and 8 lower than 1000 g) toddlers, and 21 term toddlers who were recruited from a clinic of developmental delay as the developmental delay at risk (DDR) group. The Bayley Scales of Infant and Toddler Development-Third Edition (BSID-III) and Disruptive Behavior Rating Scale-Toddler were used. The findings were as follows: (1) DDR group performed worst in BSID-III; (2) although there were no statistical differences among the NBW, MLBW, and V-ELBW groups in BSID-III, the lower the birth weight, the lower the average performance, especially in language, adaptive social behavior, and adaptive practical behavior; and (3) comparing the inattention score, the DDR group was the poorest, normal and V-ELBW groups were the best, and MLBW group was in the middle. In conclusion, low birth weight and preterm delivery affected children's inattention and development of language, adaptive social behavior, and adaptive practical behavior. Copyright © 2012.

We have previously shown short-term benefits to phonology, letter knowledge, and possibly expressive language from systematically ascertaining language delay at age 4 years followed by the Language for Learning intervention. Here, we report the trial's definitive 6-year outcomes. Randomized trial nested in a population-based ascertainment. Children with language scores >1.25 SD below the mean at age 4 were randomized, with intervention children receiving 18 1-hour home-based therapy sessions. Primary outcome was receptive/expressive language. Secondary outcomes were phonological, receptive vocabulary, literacy, and narrative skills; parent-reported pragmatic language, behavior, and health-related quality of life; costs of intervention; and health service use. For intention-to-treat analyses, trial arms were compared using linear regression models. Of 1464 children assessed at age 4, 266 were eligible and 200 randomized; 90% and 82% of intervention and control children were retained respectively. By age 6, mean language scores had normalized, but there was little evidence of a treatment effect for receptive (adjusted mean difference 2.3; 95% confidence interval [CI] -1.2 to 5.7; P = .20) or expressive (0.8; 95% CI -1.6 to 3.2; P = .49) language. Of the secondary outcomes, only phonological awareness skills (effect size 0.36; 95% CI 0.08-0.65; P = .01) showed benefit. Costs were higher for intervention families (mean difference AU$4276; 95% CI: $3424 to $5128). Population-based intervention targeting 4-year-old language delay was feasible but did not have lasting impacts on language, possibly reflecting resolution in both groups. Long-term literacy benefits remain possible but must be weighed against its cost. Copyright © 2015 by the American Academy of Pediatrics.

Pure speech delay is a common developmental disorder which, according to some estimates, affects 5%-8% of the population. Speech delay may not only be an isolated condition but also can be part of a broader condition such as global developmental delay. The present study investigated whether diffusion tensor imaging tractography-based connectome can differentiate global developmental delay from speech delay in young children. Twelve children with pure speech delay (39.1 ± 20.9 months of age, 9 boys), 14 children with global developmental delay (39.3 ± 18.2 months of age, 12 boys), and 10 children with typical development (38.5 ± 20.5 months of age, 7 boys) underwent 3T DTI. For each subject, whole-brain connectome analysis was performed by using 116 cortical ROIs. The following network metrics were measured at individual regions: strength (number of the shortest paths), efficiency (measures of global and local integration), cluster coefficient (a measure of local aggregation), and betweeness (a measure of centrality). Compared with typical development, global and local efficiency were significantly reduced in both global developmental delay and speech delay (P < .0001). The nodal strength of the cognitive network is reduced in global developmental delay, whereas the nodal strength of the language network is reduced in speech delay. This finding resulted in a high accuracy of >83% ± 4% to discriminate global developmental delay from speech delay. The network abnormalities identified in the present study may underlie the neurocognitive and behavioral consequences commonly identified in children with global developmental delay and speech delay. Further validation studies in larger samples are required. © 2016 by American Journal of Neuroradiology.

Delayed, abnormal language is a common feature of autism and language therapy often a significant component of recommended treatment. However, as with other disorders with a language component, we know surprisingly little about the language trajectories and how varied these might be across different children. Thus, we know little about how and when language problems might resolve, whether there are periods of relative stability or lack of change and what periods might offer more favourable circumstances for intervention. Expressive and receptive language was measured on six occasions between age 2 and 19 on a cohort of 192 children initially referred for autism. Latent class growth models were fitted to characterize the patterns of heterogeneous development. Latent class growth analysis identified seven classes. Between age 6 and 19, all classes tracked in parallel. Between ages 2 and 6, development was more heterogeneous with considerable variation in relative progress. In all groups, receptive and expressive language developed very largely in tandem. The results confirmed previous analysis of children with specific language impairment where progress beyond age 6 was remarkably uniform. Greater variation was evident before this age with some groups making clearly better or worse progress compared to others. While this developmental heterogeneity may simply be a reflection of variation in preexisting and unchanging biological disposition, it may also reflect, at least in part, greater sensitivity in the early years to environments that are more or less supportive of language development. These findings contribute to the case for the importance of early intervention. © 2014 The Authors.

Growth and development of children with congenital heart disease.
Chen, Chi-Wen; Li, Chung-Yi; Wang, Jou-Kou
2004-08-01
Children with congenital heart disease (CHD) commonly experience delayed growth. Because growth and development are closely related, both should be considered when a child's progress is examined. This paper reports a study to evaluate and compare the growth and development of preschool children with CHD to those of normal preschool children. The heights and weights of 42 preschool children with CHD and 116 normal preschool children were compared with standard growth curves. Differences in development of personal and social skills, fine motor skills and adaptability, language, and gross motor skills were evaluated. Developmental skills were assessed using the Denver Developmental Screening Test II. A significant difference was found in both body height (P < 0.05) and weight (P < 0.05) between the two groups. More preschoolers with congenital hear disease were below the 50th percentile in height (P < 0.05) and weight (P < 0.001). Preschoolers with CHD had more suspicious interpretations than non-CHD preschoolers, specifically in the language (P < 0.01) and gross motor sections (P < 0.001). Nevertheless, there were two items in the personal-social section and one in the language section on which the children with heart disease passed in the range of 55.6-63.2%. Problems were encountered with the Denver II test because of differences in language, culture and childrearing methods between Taiwanese and Western societies. These cultural differences must be considered when the test is used to assess development. Learning about the growth and developmental differences between children with CHD and normal children may help parents of the former to detect problems associated with delayed growth and development earlier. These children and their families should have the opportunity to participate in a long-term, follow-up programme that provides information and encourages developmental progress. The results could serve as a reference for those in both clinical and community workers who provide nursing care to children with CHD.

The purpose of the study was to extend our understanding of the Kyoto Scale of Psychological Development (KSPD) by comparison with a parent-rated scale, the Kinder Infant Development Scale (KIDS). The participants of this study were 229 children aged 0-4, who were referred to the Developmental Evaluation Center of the National Center for Child Health and Development, due to a suspected developmental disorder/delay. The participants were divided into subgroups, depending on age and overall DQ. For each group separately, correlation analyses were conducted between the Developmental Quotient (DQ) of each KSPD domain and DQ of each KIDS subscale. For high DQ group, in all ages, the KSPD Postural-Motor (P-M) domain DQ demonstrated a high correlation with the KIDS Physical-Motor DQ, and at young ages, it was also found to be moderately or strongly associated with the KIDS Manipulation DQ. For high DQ group, the KSPD Cognitive-Adaptive (C-A) domain DQ was most consistently related to the KIDS Manipulation DQ, and was also moderately correlated with the KIDS Physical-Motor DQ, Receptive Language DQ, Social Relationship with Adults DQ, Discipline DQ, and Feeding DQ, depending on age. For high DQ group, the KSPD Language-Social (L-S) DQ most consistently showed a moderate or high correlation with the KIDS Receptive Language DQ and the Manipulation DQ, and also related to Physical-Motor DQ, Expressive Language DQ, Language Conception DQ, Social Relationship with Adults DQ, and Social Relationship with Children DQ for some age groups. The low DQ group demonstrated stronger relationships on many of the pairs of the DQ of a KSPD subdomain and the DQ of a KIDS subscale, regardless of the type of subdomains and subscales. For high DQ group, the KSPD P-M domain was consistently related to parent-reported physical/motor development, the C-A domain primarily reflected a child's fine motor skills and his/her ability to understand and follow verbal instructions provided by adults, while the L-S domain was associated with parent-reported language ability. For low DQ group, the effect of global delay increased overall correlations between each domain and subscale. Further studies are necessary to replicate the findings in a larger sample including typical children. Copyright © 2015 The Japanese Society of Child Neurology. Published by Elsevier B.V.

Substantial development in social communication skills occurs in the first two years of life. Growth should be evident in sharing emotion and eye gaze; rate of communication, communicating for a variety of functions; using gestures, sounds and words; understanding language, and using functional and pretend actions with objects in play. A delay in these early social communication skills may be the first sign of a developmental delay in young children in nearly all categories of disabilities-including specific language impairment, autism spectrum disorder, HIV/AIDS, lack of environmental stimulation or institutionalization, and global developmental delays-and early detection of these delays is critical for enrolment in appropriate early intervention services. No standardized tests of early social communication skills exist for very young children in South Africa (SA). An existing evaluation tool that has the potential to be culturally fair for children from cultural backgrounds different to the standardization group is the Communication and Symbolic Behaviour Scales-Developmental Profile (CSBS DP). This study aimed to document the performance of a group of English-speaking SA children ranging in age from 12 to 24 months on the CSBS DP and to compare this performance with the original standardization sample. Sixty-seven English-speaking SA children from a range of cultural and linguistic backgrounds were assessed on the CSBS DP Behaviour Sample. Group scores were compared with the original standardization sample using inferential statistics. The results provide preliminary support for the suitability and validity of the face-to-face Behaviour Sample as a measure of early social communication skills in this sample of English-speaking SA children from a range of cultural groups between 12 and 24 months of age. While further research in the SA population is needed, these findings are a first step towards validating a culturally appropriate measure for early detection of social communication delays in a sample of SA toddlers. © 2015 Royal College of Speech and Language Therapists.

Variation in vocal-motor development in infant siblings of children with autism.
Iverson, Jana M; Wozniak, Robert H
2007-01-01
In this study we examined early motor, vocal, and communicative development in a group of younger siblings of children diagnosed with autism (Infant Siblings). Infant Siblings and no-risk comparison later-born infants were videotaped at home with a primary caregiver each month from 5 to 14 months, with follow-up at 18 months. As a group, Infant Siblings were delayed in the onset of early developmental milestones and spent significantly less time in a greater number of postures, suggestive of relative postural instability. In addition, they demonstrated attenuated patterns of change in rhythmic arm activity around the time of reduplicated babble onset; and they were highly likely to exhibit delayed language development at 18 months.

Neurodevelopment of children under 3 years of age with Smith-Magenis syndrome.
Wolters, Pamela L; Gropman, Andrea L; Martin, Staci C; Smith, Michaele R; Hildenbrand, Hanna L; Brewer, Carmen C; Smith, Ann C M
2009-10-01
Systematic data regarding early neurodevelopmental functioning in Smith-Magenis syndrome are limited. Eleven children with Smith-Magenis syndrome less than 3 years of age (mean, 19 months; range, 5-34 months) received prospective multidisciplinary assessments using standardized measures. The total sample scored in the moderately to severely delayed range in cognitive functioning, expressive language, and motor skills and exhibited generalized hypotonia, oral-motor abnormalities, and middle ear dysfunction. Socialization skills were average, and significantly higher than daily living, communication, and motor abilities, which were below average. Mean behavior ratings were in the nonautistic range. According to exploratory analyses, the toddler subgroup scored significantly lower than the infant subgroup in cognition, expressive language, and adaptive behavior, suggesting that the toddlers were more delayed than the infants relative to their respective peers. Infants aged approximately 1 year or younger exhibited cognitive, language, and motor skills that ranged from average to delayed, but with age-appropriate social skills and minimal maladaptive behaviors. At ages 2 to 3 years, the toddlers consistently exhibited cognitive, expressive language, adaptive behavior, and motor delays and mildly to moderately autistic behaviors. Combining age groups in studies may mask developmental and behavioral differences. Increased knowledge of these early neurodevelopmental characteristics should facilitate diagnosis and appropriate intervention.

Making sense of listening: the IMAP test battery.
Barry, Johanna G; Ferguson, Melanie A; Moore, David R
2010-10-11
The ability to hear is only the first step towards making sense of the range of information contained in an auditory signal. Of equal importance are the abilities to extract and use the information encoded in the auditory signal. We refer to these as listening skills (or auditory processing AP). Deficits in these skills are associated with delayed language and literacy development, though the nature of the relevant deficits and their causal connection with these delays is hotly debated. When a child is referred to a health professional with normal hearing and unexplained difficulties in listening, or associated delays in language or literacy development, they should ideally be assessed with a combination of psychoacoustic (AP) tests, suitable for children and for use in a clinic, together with cognitive tests to measure attention, working memory, IQ, and language skills. Such a detailed examination needs to be relatively short and within the technical capability of any suitably qualified professional. Current tests for the presence of AP deficits tend to be poorly constructed and inadequately validated within the normal population. They have little or no reference to the presenting symptoms of the child, and typically include a linguistic component. Poor performance may thus reflect problems with language rather than with AP. To assist in the assessment of children with listening difficulties, pediatric audiologists need a single, standardized child-appropriate test battery based on the use of language-free stimuli. We present the IMAP test battery which was developed at the MRC Institute of Hearing Research to supplement tests currently used to investigate cases of suspected AP deficits. IMAP assesses a range of relevant auditory and cognitive skills and takes about one hour to complete. It has been standardized in 1500 normally-hearing children from across the UK, aged 6-11 years. Since its development, it has been successfully used in a number of large scale studies both in the UK and the USA. IMAP provides measures for separating out sensory from cognitive contributions to hearing. It further limits confounds due to procedural effects by presenting tests in a child-friendly game-format. Stimulus-generation, management of test protocols and control of test presentation is mediated by the IHR-STAR software platform. This provides a standardized methodology for a range of applications and ensures replicable procedures across testers. IHR-STAR provides a flexible, user-programmable environment that currently has additional applications for hearing screening, mapping cochlear implant electrodes, and academic research or teaching.

This study used a prospective longitudinal design to examine the early developmental pathways that underlie language growth in infants at high risk (n = 50) and low risk (n = 34) for autism spectrum disorder in the first 18 months of life. While motor imitation and responding to joint attention (RJA) have both been found to predict expressive language in children with autism spectrum disorder and those with typical development, the longitudinal relation between these capacities has not yet been identified. As hypothesized, results revealed that 15-month RJA mediated the association between 12-month motor imitation and 18-month expressive vocabulary, even after controlling for earlier levels of RJA and vocabulary. These results provide new information about the developmental sequencing of skills relevant to language growth that may inform future intervention efforts for children at risk for language delay or other developmental challenges.

International adoption: a health and developmental prospective.
Mason, Patrick; Narad, Christine
2005-02-01
Adoptions from international countries have become an option for many US families, with over 150,000 children adopted in the past 14 years. Typically, internationally adopted children present with a host of medical and developmental concerns. Issues such as growth stunting, abnormal behaviors, and significant delays in motor, speech, and language development are likely directly related to the prenatal and early postnatal environment experienced prior to adoption. The new family and its health-care team must quickly work to identify and address these issues to aid the child's integration into his or her new family. This article will examine potential issues seen in children who are being adopted, including the impact of early environment on subsequent development. We will summarize early and long-term medical issues and review the extent of developmental delays seen in children adopted internationally. Finally, we will discuss possible mechanisms leading to the observed delays, including the impact of stress on subsequent development. By understanding the extent of expected delays and the mechanisms likely causing the issues, the health-care team will be in a good position to quickly identify and develop intervention protocols that will foster the child's assimilation into his or her new family.

Developmental outcome after a single episode of status epilepticus.
Roy, Hélène; Lippé, Sarah; Lussier, Francine; Sauerwein, Hannelore Catherine; Lortie, Anne; Lacroix, Jacques; Lassonde, Maryse
2011-08-01
Consequences of status epilepticus (SE) on psychomotor development and the specific impact of the convulsive event on emerging executive functions remain controversial. Infants treated for a single episode of SE, those treated for a single febrile seizure, and healthy infants were tested with respect to motor development, language, personal, and social skills and self-regulation. The children were divided into two age groups to investigate the impact of the convulsive event at different windows of brain maturation. We found that infants who had had SE were inferior to healthy controls on the development scales. Age differentiated SE impact on visuomotor development versus sociolinguistic development. Children who had been treated for SE had significantly more difficulties delaying a response to an attractive stimulus in one of the long-delay conditions. A single episode of SE can interfere with psychomotor and cognitive development in children without previous developmental delay, and it seems that the functions that are emerging at the time of insult are most vulnerable.

Impact of bilirubin-induced neurologic dysfunction on neurodevelopmental outcomes
Loe, Irene M.
2015-01-01
Bilirubin-induced neurologic dysfunction (BIND) is the constellation of neurologic sequelae following milder degrees of neonatal hyperbilirubinemia than are associated with kernicterus. Clinically, BIND may manifest after the neonatal period as developmental delay, cognitive impairment, disordered executive function, and behavioral and psychiatric disorders. However, there is controversy regarding the relative contribution of neonatal hyperbilirubinemia versus other risk factors to the development of later neurodevelopmental disorders in children with BIND. In this review, we focus on the empiric data from the past 25 years regarding neurodevelopmental outcomes and BIND, including specific effects on developmental delay, cognition, speech and language development, executive function, and th neurobehavioral disorders, such as attention deficit/hyperactivity disorder and autism.

Language delay in severely neglected children: a cumulative or specific effect of risk factors?
Sylvestre, Audette; Mérette, Chantal
2010-06-01
This research sought to determine if the language delay (LD) of severely neglected children under 3 years old was better explained by a cumulative risk model or by the specificity of risk factors. The objective was also to identify the risk factors with the strongest impact on LD among various biological, psychological, and environmental factors. Sixty-eight severely neglected children and their mothers participated in this cross-sectional study. Children were between 2 and 36 months of age. Data included information about the child's language development and biological, psychological, and environmental risk factors. Prevalence of LD is significantly higher in this subgroup of children than in the population as a whole. Although we observed that the risk of LD significantly increased with an increase in the cumulative count of the presence of the child's biological-psychological risk factors, the one-by-one analysis of the individual factors revealed that the cumulative effect mainly reflected the specific impact of the child's cognitive development. When we considered also the environmental risk factors, multivariate logistic regression established that cognitive development, the mother's own physical and emotional abuse experience as a child, and the mother's low acceptability level towards her child are linked to LD in severely neglected children. Language development is the result of a complex interaction between risk factors. LD in severely neglected children is better explained by the specificity of risk factors than by the cumulative risk model. Most prevention and early intervention programs promote and target an increase in the quantity and quality of language stimulation offered to the child. Our results suggest that particular attention should be given to other environmental factors, specifically the mother's psychological availability and her sensitivity towards the child. It is essential to suggest interventions targeting various ecological dimensions of neglectful mothers to help break the intergenerational neglect transmission cycle. It is also important to develop government policies and ensure that efforts among the various response networks are concerted since in-depth changes to neglect situations can only come about when all interested parties become involved.

The aim of this study was to standardize an Egyptian Arabic Pragmatic Language Test (EAPLT) using linguistically and socially suitable questions and pictures in order to be able to address specific deficits in this language domain. Questions and pictures were designed for the EAPLT to assess 3 pragmatic language subsets: pragmatic skills, functions, and factors. Ten expert phoniatricians were asked to review the EAPLT and complete a questionnaire to assess the validity of the test items. The EAPLT was applied in 120 typically developing Arabic-speaking Egyptian children (64 females and 56 males) randomly selected by inclusion and exclusion criteria in the age range between 2 years, 1 month, 1 day and 9 years, 12 months, 31 days. Children's scores were used to calculate the means and standard deviations and the 5th and 95th percentiles to determine the age of the pragmatic skills acquisition. All experts have mostly agreed that the EAPLT gives a general idea about children's pragmatic language development. Test-retest reliability analysis proved the high reliability and internal consistency of the EAPLT subsets. A statistically significant correlation was found between the test subsets and age. The EAPLT is a valid and reliable Egyptian Arabic test that can be applied in order to detect a pragmatic language delay. © 2018 S. Karger AG, Basel.

Auditory processing deficits in growth restricted fetuses affect later language development.
Kisilevsky, Barbara S; Davies, Gregory A L
2007-01-01
An increased risk for language deficits in infants born growth restricted has been reported in follow-up studies for more than 20 years, suggesting a relation between fetal auditory system development and later language learning. Work with animal models indicate that there are at least two ways in which growth restriction could affect the development of auditory perception in human fetuses: a delay in myelination or conduction and an increase in sensorineural threshold. Systematic study of auditory function in growth restricted human fetuses has not been reported. However, results of studies employing low-risk fetuses delivering as healthy full-term infants demonstrate that, by late gestation, the fetus can hear, sound properties modulate behavior, and sensory information is available from both inside (e.g., maternal vascular) and outside (e.g., noise, voices, music) of the maternal body. These data provide substantive evidence that the auditory system is functioning and that environmental sounds are available for shaping neural networks and laying the foundation for language acquisition before birth. We hypothesize that fetal growth restriction affects auditory system development, resulting in atypical auditory information processing in growth restricted fetuses compared to healthy, appropriately-grown-for-gestational-age fetuses. Speech perception that lays the foundation for later language competence will differ in growth restricted compared to normally grown fetuses and be associated with later language abilities.

Enlargement of the lateral ventricles is thought to originate from abnormal prenatal brain development and is associated with neurodevelopmental disorders. Fetal isolated mild ventriculomegaly (MVM) is associated with the enlargement of lateral ventricle volumes in the neonatal period and developmental delays in early childhood. However, little is known about postnatal brain development in these children. Twenty-eight children with fetal isolated MVM and 56 matched controls were followed at ages 1 and 2 years with structural imaging on a 3T Siemens scanner and assessment of cognitive development with the Mullen Scales of Early Learning. Lateral ventricle, total gray and white matter volumes, and Mullen cognitive composite scores and subscale scores were compared between groups. Compared to controls, children with prenatal isolated MVM had significantly larger lateral ventricle volumes at ages 1 and 2 years. Lateral ventricle volume at 1 and 2 years of age was significantly correlated with prenatal ventricle size. Enlargement of the lateral ventricles was associated with increased intracranial volumes and increased gray and white matter volumes. Children with MVM had Mullen composite scores similar to controls, although there was evidence of delay in fine motor and expressive language skills. Children with prenatal MVM have persistent enlargement of the lateral ventricles through the age of 2 years; this enlargement is associated with increased gray and white matter volumes and some evidence of delay in fine motor and expressive language development. Further study is needed to determine if enlarged lateral ventricles are associated with increased risk for neurodevelopmental disorders. Copyright © 2012 Elsevier Ltd. All rights reserved.

Refining the classification of children with selective mutism: a latent profile analysis.
Cohan, Sharon L; Chavira, Denise A; Shipon-Blum, Elisa; Hitchcock, Carla; Roesch, Scott C; Stein, Murray B
2008-10-01
The goal of this study was to develop an empirically derived classification system for selective mutism (SM) using parent-report measures of social anxiety, behavior problems, and communication delays. The sample consisted of parents of 130 children (ages 5-12) with SM. Results from latent profile analysis supported a 3-class solution made up of an anxious-mildly oppositional group, an anxious-communication delayed group, and an exclusively anxious group. Follow-up tests indicated significant group differences on measures of SM symptom severity, externalizing problems, and expressive/receptive language abilities. These results suggest that, although social anxiety is typically a prominent feature of SM, children with the disorder are also likely to present with communication delays and/or mild behavior problems.

The purpose of this study was to develop and validate a clinically useful speech-language screening procedure for young children with cleft palate ± cleft lip (CP) to identify those in need of speech-language intervention. Twenty-two children with CP were assigned to a +/- need for intervention conditions based on assessment of consonant inventory using a real-time listening procedure in combination with parent-reported expressive vocabulary. These measures allowed evaluation of early speech-language skills found to correlate significantly with later speech-language performance in longitudinal studies of children with CP. The external validity of this screening procedure was evaluated by comparing the +/- need for intervention assignment determined by the screening procedure to experienced speech-language pathologist (SLP)s' clinical judgement of whether or not a child needed early intervention. The results of real-time listening assessment showed good-excellent inter-rater agreement on different consonant inventory measures. Furthermore, there was almost perfect agreement between the children selected for intervention with the screening procedure and the clinical judgement of experienced SLPs indicate that the screening procedure is a valid way of identifying children with CP who need early intervention.

Down syndrome: Cognitive and behavioral functioning across the lifespan.
Grieco, Julie; Pulsifer, Margaret; Seligsohn, Karen; Skotko, Brian; Schwartz, Alison
2015-06-01
Individuals with Down syndrome (DS) commonly possess unique neurocognitive and neurobehavioral profiles that emerge within specific developmental periods. These profiles are distinct relative to others with similar intellectual disability (ID) and reflect underlying neuroanatomic findings, providing support for a distinctive phenotypic profile. This review updates what is known about the cognitive and behavioral phenotypes associated with DS across the lifespan. In early childhood, mild deviations from neurotypically developing trajectories emerge. By school-age, delays become pronounced. Nonverbal skills remain on trajectory for mental age, whereas verbal deficits emerge and persist. Nonverbal learning and memory are strengths relative to verbal skills. Expressive language is delayed relative to comprehension. Aspects of language skills continue to develop throughout adolescence, although language skills remain compromised in adulthood. Deficits in attention/executive functions are present in childhood and become more pronounced with age. Characteristic features associated with DS (cheerful, social nature) are personality assets. Children are at a lower risk for psychopathology compared to other children with ID; families report lower levels of stress and a more positive outlook. In youth, externalizing behaviors may be problematic, whereas a shift toward internalizing behaviors emerges with maturity. Changes in emotional/behavioral functioning in adulthood are typically associated with neurodegeneration and individuals with DS are higher risk for dementia of the Alzheimer's type. Individuals with DS possess many unique strengths and weaknesses that should be appreciated as they develop across the lifespan. Awareness of this profile by professionals and caregivers can promote early detection and support cognitive and behavioral development. © 2015 Wiley Periodicals, Inc.

The Bayley Scales of Infant and Toddler Development (III) is a tool developed in a Western setting. To evaluate the development of a group of inner city children in South Africa with no neonatal risk factors using the Bayley Scales of Infant and Toddler Development (III), to determine an appropriate cut-off to define developmental delay, and to establish variation in scores done in the same children before and after one year of age. Cohort follow-up study. 74 children had at least one Bayley III assessment at a mean age of 19.4 months (95% CI 18.4 to 20.4). The mean composite cognitive score was 92.2 (95% CI 89.4 to 95.0), the mean composite language score was 94.8 (95% CI 92.5 to 97.1), and mean composite motor score was 98.8 (95% CI 96.8 to 101.0). No child had developmental delay using a cut-off score of 70. In paired assessments above and below one year of age, the cognitive score remained unchanged, the language score decreased significantly ( p = 0.001), and motor score increased significantly ( p = 0.004) between the two ages. The Bayley Scales of Infant and Toddler Development (III) is a suitable tool for assessing development in urban children in southern Africa.

Background The question of whether Asperger syndrome can be distinguished from autism has attracted much debate and may even incur delay in diagnosis and intervention. Accordingly, there has been a proposal for Asperger syndrome to be subsumed under autism in the forthcoming Diagnostic and Statistical Manual of Mental Disorders, fifth edition, in 2013. One approach to resolve this question has been to adopt the criterion of absence of clinically significant language or cognitive delay — essentially, the “absence of language delay.” To our knowledge, this is the first meta-analysis of magnetic resonance imaging (MRI) studies of people with autism to compare absence with presence of language delay. It capitalizes on the voxel-based morphometry (VBM) approach to systematically explore the whole brain for anatomic correlates of delay and no delay in language acquisition in people with autism spectrum disorders. Methods We conducted a systematic search for VBM MRI studies of grey matter volume in people with autism. Studies with a majority (at least 70%) of participants with autism diagnoses and a history of language delay were assigned to the autism group (n = 151, control n = 190). Those with a majority (at least 70%) of individuals with autism diagnoses and no language delay were assigned to the Asperger syndrome group (n = 149, control n = 214). We entered study coordinates into anatomic likelihood estimation meta-analysis software with sampling size weighting to compare grey matter summary maps driven by Asperger syndrome or autism. Results The summary autism grey matter map showed lower volumes in the cerebellum, right uncus, dorsal hippocampus and middle temporal gyrus compared with controls; grey matter volumes were greater in the bilateral caudate, prefrontal lobe and ventral temporal lobe. The summary Asperger syndrome map indicated lower grey matter volumes in the bilateral amygdala/hippocampal gyrus and prefrontal lobe, left occipital gyrus, right cerebellum, putamen and precuneus compared with controls; grey matter volumes were greater in more limited regions, including the bilateral inferior parietal lobule and the left fusiform gyrus. Both Asperger syndrome and autism studies reported volume increase in clusters in the ventral temporal lobe of the left hemisphere. Limitations We assigned studies to autism and Asperger syndrome groups for separate analyses of the data and did not carry out a direct statistical group comparison. In addition, studies available for analysis did not capture the entire spectrum, therefore we cannot be certain that our findings apply to a wider population than that sampled. Conclusion Whereas grey matter differences in people with Asperger syndrome compared with controls are sparser than those reported in studies of people with autism, the distribution and direction of differences in each category are distinctive.

The summary Asperger syndrome map indicated lower grey matter volumes in the bilateral amygdala/hippocampal gyrus and prefrontal lobe, left occipital gyrus, right cerebellum, putamen and precuneus compared with controls; grey matter volumes were greater in more limited regions, including the bilateral inferior parietal lobule and the left fusiform gyrus. Both Asperger syndrome and autism studies reported volume increase in clusters in the ventral temporal lobe of the left hemisphere. We assigned studies to autism and Asperger syndrome groups for separate analyses of the data and did not carry out a direct statistical group comparison. In addition, studies available for analysis did not capture the entire spectrum, therefore we cannot be certain that our findings apply to a wider population than that sampled. Whereas grey matter differences in people with Asperger syndrome compared with controls are sparser than those reported in studies of people with autism, the distribution and direction of differences in each category are distinctive. © 2011 Canadian Medical Association

Deaf children's non-verbal working memory is impacted by their language experience
Marshall, Chloë; Jones, Anna; Denmark, Tanya; Mason, Kathryn; Atkinson, Joanna; Botting, Nicola; Morgan, Gary
2015-01-01
Several recent studies have suggested that deaf children perform more poorly on working memory tasks compared to hearing children, but these studies have not been able to determine whether this poorer performance arises directly from deafness itself or from deaf children's reduced language exposure. The issue remains unresolved because findings come mostly from (1) tasks that are verbal as opposed to non-verbal, and (2) involve deaf children who use spoken communication and therefore may have experienced impoverished input and delayed language acquisition. This is in contrast to deaf children who have been exposed to a sign language since birth from Deaf parents (and who therefore have native language-learning opportunities within a normal developmental timeframe for language acquisition). A more direct, and therefore stronger, test of the hypothesis that the type and quality of language exposure impact working memory is to use measures of non-verbal working memory (NVWM) and to compare hearing children with two groups of deaf signing children: those who have had native exposure to a sign language, and those who have experienced delayed acquisition and reduced quality of language input compared to their native-signing peers. In this study we investigated the relationship between NVWM and language in three groups aged 6–11 years: hearing children (n = 28), deaf children who were native users of British Sign Language (BSL; n = 8), and deaf children who used BSL but who were not native signers (n = 19). We administered a battery of non-verbal reasoning, NVWM, and language tasks. We examined whether the groups differed on NVWM scores, and whether scores on language tasks predicted scores on NVWM tasks. For the two executive-loaded NVWM tasks included in our battery, the non-native signers performed less accurately than the native signer and hearing groups (who did not differ from one another). Multiple regression analysis revealed that scores on the vocabulary measure predicted scores on those two executive-loaded NVWM tasks (with age and non-verbal reasoning partialled out). Our results suggest that whatever the language modality—spoken or signed—rich language experience from birth, and the good language skills that result from this early age of acquisition, play a critical role in the development of NVWM and in performance on NVWM tasks.

Floating-Harbor Syndrome (FHS) is a very rare condition of unknown etiology characterized by short stature, delayed bone age, characteristic facial features, delayed language skills and usually normal motor development. This syndrome has only once been associated with growth hormone deficiency and precocious puberty in the same patient. We describe a 5 4/12 year-old girl with the typical features of FHS in whom growth hormone deficiency was diagnosed and two years later central precocious puberty was noted. The patient showed a good response to human recombinant growth hormone as well as gonadotropin releasing hormone analogue treatment.

Investigating the extent of neuroplasticity: Writing in children with perinatal stroke.
Woolpert, Darin; Reilly, Judy S
2016-08-01
The developing brain is remarkably plastic, as evidenced by language studies of children with perinatal stroke (PS). Despite initial delays and in contrast to adults with comparable lesions, children with PS perform comparably to their age-matched peers in free conversation by school age. Recent studies of spoken language in older children with PS have indicated limits to neural plasticity. Writing, a cognitively demanding and language dependent domain, is understudied in children with PS. Investigating writing development will provide another perspective on the continuing linguistic development in this population. Written language performance in 43 children with PS and 60 of their typically-developing (TD) peers was evaluated to further investigate the breadth and limits to neural plasticity. Two tasks of varying difficulty were administered: a picture description, which provided a referent to facilitate writing for the children, and a more challenging autobiographical narrative. Texts were analyzed across three broad writing dimensions - productivity, complexity, and linguistic accuracy. Group differences were primarily found on accuracy indices. Morphological accuracy was most impacted by early brain injury and older children with PS did not have higher morphological accuracy than their younger counterparts, suggesting limited development with age. There were no differences in performance based on hemisphere of lesion. In addition to enhancing our understanding of long-term language outcomes in children with PS, the results further illuminate the extent and limitations of early neural plasticity for language.

Objective Individuals with autism and schizophrenia exhibit atypical language and social symptoms. The extent to which these symptoms are evident during development and in current functioning is unclear. Method Three groups of patients aged 11–20 diagnosed as clinical-high-risk for psychosis (CHR; n = 15), first episode psychosis (FEP; n = 16), and autism spectrum disorders (ASD; n = 20), plus typically developing individuals (TYP; n = 20) were compared on common autism parent-report questionnaires assessing social and language development and current functioning including the Social Communication Questionnaire, the Children’s Communication Checklist, and the Social Reciprocity Scale. Results All clinical groups demonstrated atypical social and language development, with social impairment highest in ASD. Twenty percent of participants with CHR and FEP met diagnostic criteria for ASD as assessed by parent-report. ASD exhibited greater current syntactic, and pragmatic language symptoms including delayed echolalia, pedantic speech, and deficits in appreciating irony and sarcasm. All clinical groups exhibited current deficits in social functioning. CHR and FE had similar and intermediate levels of functioning relative to ASD and TYP, with CHR generally scoring closer to TYP, providing construct validity for the CHR diagnostic label. Conclusions The results of this study suggest that ASDs, CHR, and FEP share common features of atypical neurodevelopment of language and social function. Evidence of impaired social reciprocity across both disorders and distinct language symptoms in ASDs provides important information for differential diagnosis and psychosis prevention, as well as leads for future investigations of comparative genetics and pathophysiology.

Peer social skills and theory of mind in children with autism, deafness, or typical development.
Peterson, Candida; Slaughter, Virginia; Moore, Chris; Wellman, Henry M
2016-01-01
Consequences of theory of mind (ToM) development for daily social lives of children are uncertain. Five to 13-year-olds (N = 195) with typical development, autism, or deafness (both native and late signers) took ToM tests and their teachers reported on their social skills for peer interaction (e.g., leadership, group entry). Groups differed in both ToM understanding (with late-signing deaf children especially delayed even relative to autistic children) and peer social skills (with autistic children especially delayed even relative to deaf late signers). Crucially, for the typically developing hearing children and deaf children alike, ToM understanding independently predicted peer social skills over and above age, gender, language ability, and, for deaf children, status as native- or late-signer. These novel findings offer some of the best evidence to date of the relevance of ToM cognitions to real-world social behavior for both these groups. However, for those with autism spectrum disorders (ASD) the pattern was different. The apparent link of ToM to peer competence was not a direct one but instead was significantly mediated by language ability. Several possible explanations for this intriguing autism-specific result were also discussed. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

Screening 5 and 6 year-old children starting primary school for development and language.
Yılmaz, Deniz; Bayar-Muluk, Nuray; Bayoğlu, Birgül; İdil, Aysun; Anlar, Banu
2016-01-01
Beginning school is an important milestone for children. Children's readiness for school involves cognitive, physical, and emotional development. Certain school programs allow children to start first grade after 66 months of age, together with 72 month-old children. In order to estimate school readiness, we screened children before starting first grade and compared their school performance according to their age and socio-demographic characteristics. Marmara School Readiness, Denver II developmental screening, and language assessment tests were applied. Language delays were more frequent and school readiness test scores were lower in the younger group compared to older children. However, school achievement did not differ between the two age groups. Preschool education, parental income and education affected performance in most tests. Preschool screening seems effective in detecting children with lower than average developmental skills, and the school system may provide a practical opportunity for providing support to those children.

Precursors of Reading Difficulties in Czech and Slovak Children At-Risk of Dyslexia.
Moll, Kristina; Thompson, Paul A; Mikulajova, Marina; Jagercikova, Zuzana; Kucharska, Anna; Franke, Helena; Hulme, Charles; Snowling, Margaret J
2016-05-01
Children with preschool language difficulties are at high risk of literacy problems; however, the nature of the relationship between delayed language development and dyslexia is not understood. Three hundred eight Slovak and Czech children were recruited into three groups: family risk of dyslexia, speech/language difficulties and controls, and were assessed three times from kindergarten until Grade 1. There was a twofold increase in probability of reading problems in each risk group. Precursors of 'dyslexia' included difficulties in oral language and code-related skills (phoneme awareness, letter-knowledge and rapid automatized naming); poor performance in phonological memory and vocabulary was observed in both affected and unaffected high-risk peers. A two-group latent variable path model shows that early language skills predict code-related skills, which in turn predict literacy skills. Findings suggest that dyslexia in Slavic languages has its origins in early language deficits, and children who succumb to reading problems show impaired code-related skills before the onset of formal reading instruction.

BACKGROUND Rare mutations affecting the FOXP2 transcription factor cause a monogenic speech and language disorder. We hypothesized that neural pathways downstream of FOXP2 influence more common phenotypes, such as specific language impairment. METHODS We performed genomic screening for regions bound by FOXP2 using chromatin immunoprecipitation, which led us to focus on one particular gene that was a strong candidate for involvement in language impairments. We then tested for associations between single-nucleotide polymorphisms (SNPs) in this gene and language deficits in a well-characterized set of 184 families affected with specific language impairment. RESULTS We found that FOXP2 binds to and dramatically down-regulates CNTNAP2, a gene that encodes a neurexin and is expressed in the developing human cortex. On analyzing CNTNAP2 polymorphisms in children with typical specific language impairment, we detected significant quantitative associations with nonsense-word repetition, a heritable behavioral marker of this disorder (peak association, P = 5.0×10-5 at SNP rs17236239). Intriguingly, this region coincides with one associated with language delays in children with autism. CONCLUSIONS The FOXP2-CNTNAP2 pathway provides a mechanistic link between clinically distinct syndromes involving disrupted language. PMID:18987363

Background Does poor language ability in early childhood increase the likelihood of physical aggression or is language ability delayed by frequent physical aggression? This study examined the longitudinal associations between physical aggression and language ability from toddlerhood to early childhood in a population sample while controlling for parenting behaviours, non-verbal intellectual functioning, and children’s sex. Methods Children enrolled in the Quebec Longitudinal Study of Child Development (QLSCD) (N = 2, 057) were assessed longitudinally from 17 to 72 months via parent reports and standardized assessments. Results The cross-lagged models revealed modest reciprocal associations between physical aggression and language performance from 17 to 41 months but not thereafter. Conclusions Significant associations between physical aggression and poor language ability are minimal and limited to the period when physical aggression and language performance are both substantially increasing. During that period parenting behaviours may play an important role in supporting language ability while reducing the frequency of physical aggression. Further studies are needed that utilize multiple assessments of physical aggression, assess multiple domains of language abilities, and that examine the potential mediating role of parenting behaviours between 12 and 48 months.

Who Receives Speech/Language Services by 5 Years of Age in the United States?
Hammer, Carol Scheffner; Farkas, George; Hillemeier, Marianne M.; Maczuga, Steve; Cook, Michael; Morano, Stephanie
2016-01-01
Purpose We sought to identify factors predictive of or associated with receipt of speech/language services during early childhood. We did so by analyzing data from the Early Childhood Longitudinal Study–Birth Cohort (ECLS-B; Andreassen & Fletcher, 2005), a nationally representative data set maintained by the U.S. Department of Education. We addressed two research questions of particular importance to speech-language pathology practice and policy. First, do early vocabulary delays increase children's likelihood of receiving speech/language services? Second, are minority children systematically less likely to receive these services than otherwise similar White children? Method Multivariate logistic regression analyses were performed for a population-based sample of 9,600 children and families participating in the ECLS-B. Results Expressive vocabulary delays by 24 months of age were strongly associated with and predictive of children's receipt of speech/language services at 24, 48, and 60 months of age (adjusted odds ratio range = 4.32–16.60). Black children were less likely to receive speech/language services than otherwise similar White children at 24, 48, and 60 months of age (adjusted odds ratio range = 0.42–0.55). Lower socioeconomic status children and those whose parental primary language was other than English were also less likely to receive services. Being born with very low birth weight also significantly increased children's receipt of services at 24, 48, and 60 months of age. Conclusion Expressive vocabulary delays at 24 months of age increase children’s risk for later speech/language services. Increased use of culturally and linguistically sensitive practices may help racial/ethnic minority children access needed services. PMID:26579989

Impact of bilirubin-induced neurologic dysfunction on neurodevelopmental outcomes.
Wusthoff, Courtney J; Loe, Irene M
2015-02-01
Bilirubin-induced neurologic dysfunction (BIND) is the constellation of neurologic sequelae following milder degrees of neonatal hyperbilirubinemia than are associated with kernicterus. Clinically, BIND may manifest after the neonatal period as developmental delay, cognitive impairment, disordered executive function, and behavioral and psychiatric disorders. However, there is controversy regarding the relative contribution of neonatal hyperbilirubinemia versus other risk factors to the development of later neurodevelopmental disorders in children with BIND. In this review, we focus on the empiric data from the past 25 years regarding neurodevelopmental outcomes and BIND, including specific effects on developmental delay, cognition, speech and language development, executive function, and the neurobehavioral disorders, such as attention deficit/hyperactivity disorder and autism.

The shape bias-generalising labels to same shaped objects-has been linked to attentional learning or referential intent. We explore these origins in children with typical development (TD), autism spectrum disorders (ASD) and other developmental disorders (DD). In two conditions, a novel object was presented and either named or described. Children selected another from a shape, colour or texture match. TD children choose the shape match in both conditions, children with DD and 'high-verbal mental age' (VMA) children with ASD (language age > 4.6) did so in the name condition and 'low-VMA' children with ASD never showed the heuristic. Thus, the shape bias arises from attentional learning in atypically developing children and is delayed in ASD.

Disrupted neural synchronization in toddlers with autism
Dinstein, Ilan; Pierce, Karen; Eyler, Lisa; Solso, Stephanie; Malach, Rafael; Behrmann, Marlene; Courchesne, Eric
2011-01-01
Summary Autism is often described as a disorder of neural synchronization. However, it is unknown how early in development synchronization abnormalities emerge and whether they are related to the development of early autistic behavioral symptoms. Here, we show that disrupted synchronization is evident in the spontaneous cortical activity of naturally sleeping toddlers with autism, but not in toddlers with language delay or typical development. Toddlers with autism exhibited significantly weaker inter-hemispheric synchronization (i.e. weak “functional connectivity” across the two hemispheres) in putative language areas. The strength of synchronization was positively correlated with verbal ability, negatively correlated with autism severity, and enabled identification of the majority of autistic toddlers (72%) with high accuracy (84%). Disrupted cortical synchronization, therefore, appears to be a notable characteristic of autism neurophysiology that is evident at very early stages of autism development. PMID:21689606

Severe Expressive-Language Delay Related to Duplication of the Williams–Beuren Locus

SUMMARY The Williams–Beuren syndrome (WBS) locus, at 7q11.23, is prone to recurrent chromosomal rearrangements, including the microdeletion that causes WBS, a multisystem condition with characteristic cardiovascular, cognitive, and behavioral features. It is hypothesized that reciprocal duplications of the WBS interval should also occur, and here we present such a case description. The most striking phenotype was a severe delay in expressive speech, in contrast to the normal articulation and fluent expressive language observed in persons with WBS. Our results suggest that specific genes at 7q11.23 are exquisitely sensitive to dosage alterations that can influence human language and visuospatial capabilities. PMID:16236740

Uh and um in Children With Autism Spectrum Disorders or Language Impairment
Gorman, Kyle; Olson, Lindsay; Presmanes Hill, Alison; Lunsford, Rebecca; Heeman, Peter A.; van Santen, Jan P. H.
2016-01-01
Atypical pragmatic language is often present in individuals with autism spectrum disorders (ASD), along with delays or deficits in structural language. This study investigated the use of the “fillers” uh and um by children ages 4–8 during the autism diagnostic observation schedule. Fillers reflect speakers’ difficulties with planning and delivering speech, but they also serve communicative purposes, such as negotiating control of the floor or conveying uncertainty. We hypothesized that children with ASD would use different patterns of fillers compared to peers with typical development or with specific language impairment (SLI), reflecting differences in social ability and communicative intent. Regression analyses revealed that children in the ASD group were much less likely to use um than children in the other two groups. Filler use is an easy-to-quantify feature of behavior that, in concert with other observations, may help to distinguish ASD from SLI. PMID:26800246

Women from high-mortality settings in sub-Saharan Africa can remain at risk for adverse maternal outcomes even after migrating to low-mortality settings. To conceptualise underlying socio-cultural factors, we assume a 'maternal migration effect' as pre-migration influences on pregnant women's post-migration care-seeking and consistent utilisation of available care. We apply the 'three delays' framework, developed for low-income African contexts, to a high-income western scenario, and aim to identify delay-causing influences on the pathway to optimal facility treatment. We also compare factors influencing the expectations of women and maternal health providers during care encounters. In 2005-2006, we interviewed 54 immigrant African women and 62 maternal providers in greater London, United Kingdom. Participants were recruited by snowball and purposive sampling. We used a hermeneutic, naturalistic study design to create a qualitative proxy for medical anthropology. Data were triangulated to the framework and to the national health system maternity care guidelines. This maintained the original three phases of (1) care-seeking, (2) facility accessibility, and (3) receipt of optimal care, but modified the framework for a migration context. Delays to reciprocal care encounters in Phase 3 result from Phase 1 factors of 'broken trust, which can be mutually held between women and providers. An additional factor is women's 'negative responses to future care', which include rationalisations made during non-emergency situations about future late-booking, low-adherence or refusal of treatment. The greatest potential for delay was found during the care encounter, suggesting that perceived Phase 1 factors have stronger influence on Phase 3 than in the original framework. Phase 2 'language discordance' can lead to a 'reliance on interpreter service', which can cause delays in Phase 3, when 'reciprocal incongruent language ability' is worsened by suboptimal interpreter systems. 'Non-reciprocating care conceptualisations', 'limited system-level care guidelines', and 'low staff levels' can additionally delay timely care in Phase 3. Copyright © 2012 Elsevier Ltd.

Rural and remote speech-language pathology service inequities: An Australian human rights dilemma.
Jones, Debra M; McAllister, Lindy; Lyle, David M
2018-02-01
Access to healthcare is a fundamental human right for all Australians. Article 19 of the Universal Declaration of Human Rights acknowledges the right to freedom of opinion and to seek, receive and impart information and ideas. Capacities for self-expression and effective communication underpin the realisation of these fundamental human rights. For rural and remote Australian children this realisation is compromised by complex disadvantages and inequities that contribute to communication delays, inequity of access to essential speech-language pathology services and poorer later life outcomes. Localised solutions to the provision of civically engaged, accessible, acceptable and sustainable speech-language pathology services within rural and remote Australian contexts are required if we are to make substantive human rights gains. However, civically engaged and sustained healthcare can significantly challenge traditional professionalised perspectives on how best to design and implement speech-language pathology services that seek to address rural and remote communication needs and access inequities. A failure to engage these communities in the identification of childhood communication delays and solutions to address these delays, ultimately denies children, families and communities of their human rights for healthcare access, self-expression, self-dignity and meaningful inclusion within Australian society.

To verify the language and cognitive profile of children with dyslexia, contributing to the diagnosis of this condition in readers of a regular orthography, such as Brazilian Portuguese. In this study, 47 children with dyslexia (GD) and two controlled groups, one composed of 41 age controls (GCI) and the other with 31 reading controls (GCL), participated. All children were submitted to a battery involving the above-mentioned abilities. GD demonstrated predominant deficits in phonological processing, which were not compatible with a delay in the development of such abilities, indicating an atypical development. The GD also obtained lower scores in both basic and more complex reading and writing skills (i.e., letters, words, pseudowords, and texts, respectively), as well as in other domains, such as language (syntactic processing and oral sentence comprehension), which may be a result of a deficit in phonological skills, that interfered with higher complexity linguistic skills. Phonological abilities demonstrated to be the main difficulty observed in children with dyslexia investigated in this study, corroborating previous studies in other languages. This demonstrates that, independently of the language regularity, phonological skills are fundamental to the diagnosis of developmental dyslexia.

This article presents an updated review about the definition, diagnostic criteria, classifications, etiology and the evolution of the specific language impairment (SLI). The specific language impairment is characterized by a developmental language delay and an impaired language, that persist over time and it is not explained by sensorial, motor and mental disabilities, neither by psycopathological disorders, socio-emotional deprivation, nor brain injury. The diagnosis is based on exclusional criteria. Some researchers propose different classifications considering the children performance in language comprehension and language production. Genetical linkage to the FOXP2 gen in the SPCH1 region of the chromosome 7 and to the chromosomes 13, 16 y 19 has been reported. The neuroimage studies have shown alterations in the volume and perfusion of some brain structures related to language. The manifestations of SLI may change during the development of the children and may disturb the self-esteem, the academic performance and the social abilities. The variability in the linguistic and cognitive performance, and the variety in the etiological findings in children with SLI, don't allow to settle the affected population as an homogeneous group. Different theoretical positions have emerged as a consequence of this condition.

Purpose The purpose of this study was to measure the effect of time to response in a fast-mapping word learning task for children with Specific Language Impairment (SLI) and children with typically-developing language skills (TD). Manipulating time to response allows us to examine decay of the memory trace, the use of vocal rehearsal, and their effects on word learning. Method Participants included 40 school-age children: half with SLI and half with TD. The children were asked to expressively and receptively fast-map 24 novel labels for 24 novel animated dinosaurs. They were asked to demonstrate learning either immediately after presentation of the novel word or after a 10-second delay. Data were collected on the use of vocal rehearsal and for recognition and production accuracy. Results Although the SLI group was less accurate overall, there was no evidence of decay of the memory trace. Both groups used vocal rehearsal at comparable rates, which did not vary when learning was tested immediately or after a delay. Use of vocal rehearsal resulted in better accuracy on the recognition task, but only for the TD group. Conclusions A delay in time to response without interference was not an undue burden for either group. Despite the fact that children with SLI used a vocal rehearsal strategy as often as unimpaired peers, they did not benefit from the strategy in the same way as their peers. Possible explanations for these findings and clinical implications will be discussed. PMID:21885056

Profile of referrals for early childhood developmental delay to ambulatory subspecialty clinics.
Shevell, M I; Majnemer, A; Rosenbaum, P; Abrahamowicz, M
2001-09-01
The objective of this study was to determine the profile and pattern of referral to subspecialty clinics of young children with suspected developmental delay together with the factors prompting their referral. All children under 5 years of age referred to either developmental pediatrics or pediatric neurology clinics at a single tertiary hospital over an 18-month period were prospectively identified. Standardized demographic and referral information were collected at intake, final developmental delay subtype diagnosed was identified, and referring physicians were surveyed regarding factors prompting referral. A total of 224 children met study criteria. There was a marked male preponderance (166/224), especially among those with either cognitive or language delay. Two delay subtypes, global developmental delay and developmental language disorder, accounted for two thirds of the diagnoses made. For slightly more than one third of the children (75/224), the delay subtype diagnosed following specialty evaluation was different from that initially suspected by the referring physician. A mean delay of 15.5 months was observed for the cohort as a whole between initial parental concern and specialty assessment. For referring physicians, the major factor prompting referral was the severity of the observed delay. The most important aspects of the specialty evaluation according to referral sources were the identification of a possible etiology and confirmation of delay. A profile of referrals and the rationale thereof for a cohort of children with suspected developmental delay is presented that, although locale specific, has implications for service provision and training.

Australia is a diverse society: 26% of the population were born overseas, a further 20% have at least one parent born overseas and 19% speak a language other than English at home. Paediatricians are frequently involved in the assessment and management of non-English-speaking-background children with developmental delay, disability or learning issues. Despite the diversity of our patient population, information on how children learn additional or later languages is remarkably absent in paediatric training. An understanding of second language acquisition is essential to provide appropriate advice to this patient group. It takes a long time (5 years or more) for any student to develop academic competency in a second language, even a student who has received adequate prior schooling in their first language. Refugee students are doubly disadvantaged as they frequently have limited or interrupted prior schooling, and many are unable to read and write in their first language. We review the evidence on second language acquisition during childhood, describe support for English language learners within the Australian education system, consider refugee-background students as a special risk group and address common misconceptions about how children learn English as an additional language. © 2013 The Authors.

This study examined the extent to which a discrepant comprehension-production profile (i.e., relatively more delayed comprehension than production) is characteristic of the early language phenotype in autism spectrum disorders (ASD) and tracked the developmental progression of the profile. Our findings indicated that a discrepant comprehension-production profile distinguished toddlers (30 months) with ASD from late talkers without ASD (91% sensitivity, 100% specificity) in groups that were comparable on expressive language, age, and socioeconomic status. Longitudinal data for children with ASD revealed that the discrepant profile steadily decreased from 30 to 44 months until there was no significant comprehension-production difference at 66 months. In conclusion, results suggest that lower comprehension than production may be an age-specific marker of toddlers with ASD.

Lexical and grammatical skills in toddlers on the autism spectrum compared to late talking toddlers.
Ellis Weismer, Susan; Gernsbacher, Morton Ann; Stronach, Sheri; Karasinski, Courtney; Eernisse, Elizabeth R; Venker, Courtney E; Sindberg, Heidi
2011-08-01
This study compared language development in 30-month-old toddlers on the autism spectrum and 25- month-old late talking toddlers without autism. Groups were matched on overall productive vocabulary (and nonverbal cognition was controlled) in order to compare language acquisition patterns related to vocabulary composition and early lexical–grammatical relationships. Findings revealed that semantic categories of words— including psychological state terms—used by toddlers on the autism spectrum were very similar to those of late talkers. Both groups were equivalent with respect to grammatical complexity and proportion of toddlers combining words, though late talkers displayed a relatively stronger association between lexical–grammatical abilities. These tentative findings are consistent with a dimensional account of early, core linguistic abilities across different populations of children with language delay.

Prosodic skills in children with Down syndrome and in typically developing children.
Zampini, Laura; Fasolo, Mirco; Spinelli, Maria; Zanchi, Paola; Suttora, Chiara; Salerni, Nicoletta
2016-01-01
Many studies have analysed language development in children with Down syndrome to understand better the nature of their linguistic delays and the reason why these delays, particularly those in the morphosyntactic area, seem greater than their cognitive impairment. However, the prosodic characteristics of language development in children with Down syndrome have been scarcely investigated. To analyse the prosodic skills of children with Down syndrome in the production of multi-word utterances. Data on the prosodic skills of these children were compared with data on typically developing children matched on developmental age and vocabulary size. Between-group differences and the relationships between prosodic and syntactic skills were investigated. The participants were nine children with Down syndrome (who ranged in chronological age from 45 to 63 months and had a mean developmental age of 30 months) and 12 30-month-old typically developing children. The children in both groups had a vocabulary size of approximately 450 words. The children's spontaneous productions were recorded during observations of mother-child play sessions. Data analyses showed that despite their morphosyntactic difficulties, children with Down syndrome were able to master some aspects of prosody in multi-word utterances. They were able to produce single intonation multi-word utterances on the same level as typically developing children. In addition, the intonation contour of their utterances was not negatively influenced by syntactic complexity, contrary to what occurred in typically developing children, although it has to be considered that the utterances produced by children with Down syndrome were less complex than those produced by children in the control group. However, children with Down syndrome appeared to be less able than typically developing children to use intonation to express the pragmatic interrogative function. The findings are discussed considering the effects of social experience on the utterance prosodic realization. © 2015 Royal College of Speech and Language Therapists.

A left cerebellar pathway mediates language in prematurely-born young adults

Preterm (PT) subjects are at risk for developmental delay, and task-based studies suggest that developmental disorders may be due to alterations in neural connectivity. Since emerging data imply the importance of right cerebellar function for language acquisition in typical development, we hypothesized that PT subjects would have alternate areas of cerebellar connectivity, and that these areas would be responsible for differences in cognitive outcomes between PT subjects and term controls at age 20 years. Nineteen PT and 19 term control young adults were prospectively studied using resting-state functional MRI (fMRI) to create voxel-based contrast maps reflecting the functional connectivity of each tissue element in the grey matter through analysis of the intrinsic connectivity contrast degree (ICC-d). Left cerebellar ICC-d differences between subjects identified a region of interest that was used for subsequent seed-based connectivity analyses. Subjects underwent standardized language testing, and correlations with cognitive outcomes were assessed. There were no differences in gender, hand preference, maternal education, age at study, or Peabody Picture Vocabulary Test (PPVT) scores. Functional connectivity (FcMRI) demonstrated increased tissue connectivity in the biventer, simple and quadrangular lobules of the L cerebellum (p<0.05) in PTs compared to term controls; seed-based analyses from these regions demonstrated alterations in connectivity from L cerebellum to both R and L inferior frontal gyri (IFG) in PTs compared to term controls. For PTs but not term controls, there were significant positive correlations between these connections and PPVT scores (R IFG: r=0.555, p=0.01; L IFG: r=0.454, p=0.05), as well as Verbal Comprehension Index (VCI) scores (R IFG: r=0.472, p=0.04). These data suggest the presence of a left cerebellar language circuit in PT subjects at young adulthood. These findings may represent either a delay in maturation or the engagement of alternative neural pathways for language in the developing PT brain. PMID:22982585

The purpose of this study was to investigate the clinical characteristics of children with mental retardation (MR) of unknown etiology for early recognition and intervention. In this study, we defined children with MR of unknown etiology as those without clear etiologies for MR despite extensive evaluation and were not associated with pathological behavioral problems such as pervasive developmental disorders and attention-deficit/hyperactivity disorder. The clinical characteristics of children with MR of unknown etiology were as follows. 1) MR of unknown etiology was 48.8% of all MR. 2) MR of unknown etiology was more common in males. 3) Delayed language development was a leading factor that made the parents of children with MR of unknown etiology seek help from physicians. However, most of the children with MR of unknown etiology showed a relatively uniform delay in several areas of development. 4) Most children with MR of unknown etiology were delayed walkers. 5) Most children with MR of unknown etiology were mild cases.

This exploratory study examined the potential secondary outcome of an early augmented language intervention that incorporates speech-generating devices (SGD) on motor skill use for children with developmental delays. The data presented are from a longitudinal study by Romski and colleagues. Toddlers in the augmented language interventions were either required (Augmented Communication-Output; AC-O) or not required (Augmented Communication-Input; AC-I) to use the SGD to produce an augmented word. Three standardized assessments and five event-based coding schemes measured the participants' language abilities and motor skills. Toddlers in the AC-O intervention used more developmentally appropriate motor movements and became more accurate when using the SGD to communicate than toddlers in the AC-I intervention. AAC strategies, interventionist/parent support, motor learning opportunities, and physical feedback may all contribute to this secondary benefit of AAC interventions that use devices.

The purpose of this study was to measure the effect of time to response in a fast-mapping word learning task for children with specific language impairment (SLI) and children with typically developing language skills (TD). Manipulating time to response allows us to examine decay of the memory trace, the use of vocal rehearsal, and their effects on word learning. Participants included 40 school-age children: half with SLI and half with TD. The children were asked to expressively and receptively fast-map 24 novel labels for 24 novel animated dinosaurs. They were asked to demonstrate learning either immediately after presentation of the novel word or after a 10-second delay. Data were collected on the use of vocal rehearsal and for recognition and production accuracy. Although the SLI group was less accurate overall, there was no evidence of decay of the memory trace. Both groups used vocal rehearsal at comparable rates, which did not vary when learning was tested immediately or after a delay. Use of vocal rehearsal resulted in better accuracy on the recognition task, but only for the TD group. A delay in time to response without interference was not an undue burden for either group. Despite the fact that children with SLI used a vocal rehearsal strategy as often as unimpaired peers, they did not benefit from the strategy in the same way as their peers. Possible explanations for these findings and clinical implications will be discussed. Readers will learn about how time to response affects word learning in children with specific language impairment and unimpaired peers. They will see how this issue fits into a framework of phonological working memory. They will also become acquainted with the effect of vocal rehearsal on word learning. Copyright © 2011 Elsevier Inc.

The Relational Completion Procedure is effective for establishing same, opposite and comparative derived relations in verbally able adults, but to date it has not been used to establish relational frames in young children or those with developmental delay. In Experiment 1, the Relational Completion Procedure was used with the goal of establishing two 3-member sameness networks in nine individuals with Autism Spectrum Disorder (eight with language delay). A multiple exemplar intervention was employed to facilitate derived relational responding when required. Seven of nine participants in Experiment 1 passed tests for derived relations. In Experiment 2, eight participants (all of whom, except one, had a verbal repertoire) were given training with the aim of establishing two 4-member sameness networks. Three of these participants were typically developing young children aged between 5 and 6 years old, all of whom demonstrated derived relations, as did four of the five participants with developmental delay. These data demonstrate that it is possible to reliably establish derived relations in young children and those with developmental delay using an automated procedure. © Society for the Experimental Analysis of Behavior.

To examine which language function depends on early experience, the present study compared deaf native signers, deaf non-native signers and hearing German native speakers while processing German sentences. The participants watched simple written sentences while event-related potentials (ERPs) were recorded. At the end of each sentence they were asked to judge whether the sentence was correct or not. Two types of violations were introduced in the middle of the sentence: a semantically implausible noun or a violation of subject-verb number agreement. The results showed a similar ERP pattern after semantic violations (an N400 followed by a positivity) in all three groups. After syntactic violations, native German speakers and native signers of German sign language (DGS) with German as second language (L2) showed a left anterior negativity (LAN) followed by a P600, whereas no LAN but a negativity over the right hemisphere instead was found in deaf participants with a delayed onset of first language (L1) acquisition. The P600 of this group had a smaller amplitude and a different scalp distribution as compared to German native speakers. The results of the present study suggest that language deprivation in early childhood alters the cerebral organization of syntactic language processing mechanisms for L2. Semantic language processing instead was unaffected.

Joint attention revisited: Finding strengths among children with autism.
Hurwitz, Sarah; Watson, Linda R
2016-07-01
Differences in joint attention are prominent for some children with autism and are often used as an indicator of the disorder. This study examined the joint attention competencies of young children with autism who demonstrated joint attention ability and compared them to children with developmental delays. A total of 40 children with autism and developmental delays were matched pairwise based on mental and chronological age. Videos of children engaging in play were coded for the frequency and forms (eye contact, gestures, affect, etc.) of joint attention. Additionally, concurrent language was compared among children with autism (N = 32) by their joint attention ability. Children with autism spectrum disorder entered into joint attention significantly less often than children with developmental delays, but once engaged used the forms of joint attention similarly. For the matched pairs, there were no differences in language, but the children with autism who used joint attention had significantly better language than children with autism who did not (even after controlling for mental age). There is a group of young children with autism who can use joint attention but do so at lower frequencies than children with developmental delays. Possible reasons include difficulty disengaging attention and limited intrinsic social motivation to share. Adult persistence is recommended to encourage joint attention. © The Author(s) 2015.

Past research with children with specific language impairment (SLI) has shown them to have poorer planning and problem-solving ability, and delayed self-regulatory speech (SRS) relative to their typically developing (TD) peers. However, the studies are few in number and are restricted in terms of the number and age range of participants, which limits our understanding of the nature and extent of any delays. Moreover, no study has examined the performance of a significant subset of children with SLI, those who have hyperactive and inattentive behaviours. This cross-sectional study aimed to compare the performance of young children with SLI (aged 4-7 years) with that of their TD peers on a planning and problem-solving task and to examine the use of SRS while performing the task. Within each language group, the performance of children with and without hyperactive and inattentive behaviours was further examined. Children with SLI (n = 91) and TD children (n = 81), with and without hyperactive and inattentive behaviours across the three earliest school years (Kindergarten, Preprimary and Year 1) were video-taped while they completed the Tower of London (TOL), a planning and problem-solving task. Their recorded speech was coded and analysed to look at differences in SRS and its relation to TOL performance across the groups. Children with SLI scored lower on the TOL than TD children. Additionally, children with hyperactive and inattentive behaviours performed worse than those without hyperactive and inattentive behaviours, but only in the SLI group. This suggests that children with SLI with hyperactive and inattentive behaviours experience a double deficit. Children with SLI produced less inaudible muttering than TD children, and showed no reduction in social speech across the first three years of school. Finally, for children with SLI, a higher percentage performed better on the TOL when they used SRS than when they did not. The results point towards a significant delay in the development and internalization of SRS in the SLI group, which should be taken into account when considering the planning and problem-solving of young children with SLI. © 2016 Royal College of Speech and Language Therapists.

Disruptions of the FOXP2 gene, encoding a forkhead transcription factor, are the first known monogenic cause of a speech and language disorder. So far, mainly chromosomal rearrangements such as translocations or larger deletions affecting FOXP2 have been reported. Intragenic deletions or convincingly pathogenic point mutations in FOXP2 have up to date only been reported in three families. We thus aimed at a further characterisation of the mutational and clinical spectrum. Chromosomal microarray testing, trio exome sequencing, multigene panel sequencing and targeted sequencing of FOXP2 were performed in individuals with variable developmental disorders, and speech and language deficits. We identified four different truncating mutations, two novel missense mutations within the forkhead domain and an intragenic deletion in FOXP2 in 14 individuals from eight unrelated families. Mutations occurred de novo in four families and were inherited from an affected parent in the other four. All index patients presented with various manifestations of language and speech impairment. Apart from two individuals with normal onset of speech, age of first words was between 4 and 7 years. Articulation difficulties such as slurred speech, dyspraxia, stuttering and poor pronunciation were frequently noted. Motor development was normal or only mildly delayed. Mild cognitive impairment was reported for most individuals. By identifying intragenic deletions or mutations in 14 individuals from eight unrelated families with variable developmental delay/cognitive impairment and speech and language deficits, we considerably broaden the mutational and clinical spectrum associated with aberrations in FOXP2.

Combination antiretroviral (cARV) regimens are recommended for pregnant women with HIV to prevent perinatal HIV transmission. Safety is a concern for infants who were HIV-exposed but uninfected, particularly for neurodevelopmental problems, such as language delays. We studied late language emergence (LLE) in HIV-exposed but uninfected children enrolled in a US-based prospective cohort study. LLE was defined as a caregiver-reported score ≤10th percentile in any of 4 domains of the MacArthur-Bates Communicative Development Inventory for 1-year olds and as ≥1 standard deviation below age-specific norms for the Ages and Stages Questionnaire for 2-year olds. Logistic regression models were used to evaluate associations of in utero cARV exposure with LLE, adjusting for infant, maternal and environmental characteristics. 1129 language assessments were conducted among 792 1- and 2-year-old children (50% male, 62% black and 37% Hispanic). Overall, 86% had in utero exposure to cARV and 83% to protease inhibitors. LLE was identified in 26% of 1-year olds and 23% of 2-year olds, with higher rates among boys. In adjusted models, LLE was not associated with maternal cARV or ARV drug classes in either age group. Among cARV-exposed 1-year olds, increased odds of LLE was observed for those exposed to atazanavir (adjusted odds ratio = 1.83, 95% confidence interval: 1.10-3.04), particularly after the first trimester (adjusted odds ratio = 3.56, P = 0.001), compared with atazanavir-unexposed infants. No associations of individual ARV drugs with LLE were observed among 2-year olds. In utero cARV exposure showed little association with LLE, except for a higher risk of language delay observed in 1-year-old infants with atazanavir exposure.

Background Language impairment (LI) risk is increased for perinatally acquired human immunodeficiency virus-infected (PHIV) and perinatally exposed to HIV but uninfected (PHEU) youth. This study evaluates the persistence of LI in these groups. Methods The Clinical Evaluation of Language Fundamentals was repeated on participants of the Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol 18 months postbaseline. Regression models identified factors associated with change in standardized score (SC) and the resolution or development of LI. Results Of 319 participants, 112 had LI at baseline. Upon re-evaluation, SCs were highly stable and changes were similar in PHIV (n = 212) and PHEU (n = 107) participants. Those with family history of language delays had a 2.39 point lower mean increase in SCs than those without, after controlling for demographic and socioeconomic factors and baseline LI status. Among PHIV participants, CD4 count <350 cells/mm3 was associated with lower mean SC change (4.32 points), and exposure to combination antiretroviral therapy (cART) or protease inhibitors (PIs) was associated with a higher mean SC change (5.93 and 4.19 points, respectively). Initial LI was persistent in most cases (78%); 20 new cases occurred (10%). Female sex was associated with higher odds of LI resolution. Among PHIV, duration and baseline cART and history of PI use were associated with LI resolution; higher percentage of detectable viral loads before baseline was associated with lower odds of resolution. Conclusions The PHIV and PHEU youth are at risk for persistent LI, and family history of language delays was a risk factor for persistence of problems. Measures of successful HIV treatment predicted more favorable outcomes among PHIV youth. PMID:27856674

Reading difficulties are found in children with both high and low IQ and it is now clear that both groups exhibit difficulties in phonological processing. Here, we apply the developmental trajectories approach, a new methodology developed for studying language and cognitive impairments in developmental disorders, to both poor reader groups. The trajectory methodology enables identification of atypical versus delayed development in datasets gathered using group matching designs. Regarding the cognitive predictors of reading, which here are phonological awareness, phonological short-term memory (PSTM) and rapid automatized naming (RAN), the method showed that trajectories for the two groups diverged markedly. Children with dyslexia showed atypical development in phonological awareness, while low IQ poor readers showed developmental delay. Low IQ poor readers showed atypical PSTM and RAN development, but children with dyslexia showed developmental delay. These divergent trajectories may have important ramifications for supporting each type of poor reader, although all poor readers showed weakness in all areas. Regarding auditory processing, the developmental trajectories were very similar for the two poor reader groups. However, children with dyslexia demonstrated developmental delay for auditory discrimination of Duration, while the low IQ children showed atypical development on this measure. The data show that, regardless of IQ, poor readers have developmental trajectories that differ from typically developing children. The trajectories approach enables differences in trajectory classification to be identified across poor reader group, as well as specifying the individual nature of these trajectories. PMID:27110928

Forty-one high-risk infants (HR) with an older sibling with autism spectrum disorder (ASD) were observed longitudinally at 10, 12, 18 and 24 months of age during a tool use task in a play-like scenario. Changes in grasp types and functional actions produced with a spoon were assessed during elicited tool use. Outcome and vocabulary measures were available at 36 months, distinguishing: 11 HR-ASD, 15 HR-language delay and 15 HR-no delay. Fewer HR-ASD infants produced grasp types facilitating spoon use at 24 months and functional actions at 10 months than HR-no delay. Production of functional actions in HR infants at 10 months predicted word comprehension at 12 months and word production at 24 and 36 months.

Children's speech sound development is assessed by comparing speech production with the typical development of speech sounds based on a child's age and developmental profile. One widely used method of sampling is to elicit a single-word sample along with connected speech. Words produced spontaneously rather than imitated may give a more accurate indication of a child's speech development. A published word complexity measure can be used to score later-developing speech sounds and more complex word patterns. There is a need for a screening word list that is quick to administer and reliably differentiates children with typically developing speech from children with patterns of delayed/disordered speech. To identify a short word list based on word complexity that could be spontaneously named by most typically developing children aged 3;00-5;05 years. One hundred and five children aged between 3;00 and 5;05 years from three local authority nursery schools took part in the study. Items from a published speech assessment were modified and extended to include a range of phonemic targets in different word positions in 78 monosyllabic and polysyllabic words. The 78 words were ranked both by phonemic/phonetic complexity as measured by word complexity and by ease of spontaneous production. The ten most complex words (hereafter Triage 10) were named spontaneously by more than 90% of the children. There was no significant difference between the complexity measures for five identified age groups when the data were examined in 6-month groups. A qualitative analysis revealed eight children with profiles of phonological delay or disorder. When these children were considered separately, there was a statistically significant difference (p < 0.005) between the mean word complexity measure of the group compared with the mean for the remaining children in all other age groups. The Triage 10 words reliably differentiated children with typically developing speech from those with delayed or disordered speech patterns. The Triage 10 words can be used as a screening tool for triage and general assessment and have the potential to monitor progress during intervention. Further testing is being undertaken to establish reliability with children referred to speech and language therapy services. © 2012 Royal College of Speech and Language Therapists.

This study compared language development in 30-month-old toddlers on the autism spectrum and 25-month-old late talking toddlers without autism. Groups were matched on overall productive vocabulary (and nonverbal cognition was controlled) in order to compare language acquisition patterns related to vocabulary composition and early lexical-grammatical relationships. Findings revealed that semantic categories of words – including psychological state terms – used by toddlers on the autism spectrum were very similar to those of late talkers. Both groups were equivalent with respect to grammatical complexity and proportion of toddlers combining words, though late talkers displayed a relatively stronger association between lexical-grammatical abilities. These tentative findings are consistent with a dimensional account of early, core linguistic abilities across different populations of children with language delay. PMID:21061053

Young children under 6 years old are over-represented in the U.S. child welfare system (CWS). Due to their exposure to early deprivation and trauma, they are also highly vulnerable to developmental problems, including language delays. High quality early care and education (ECE) programs (e.g. preschool, Head Start) can improve children's development and so policymakers have begun calling for increased enrollment of CWS-supervised children in these programs. However, it is not a given that ECE will benefit all children who experience maltreatment. Some types of maltreatment may result in trauma-related learning and behavior challenges or developmental deficits that cause children to respond to ECE settings differently. The current study uses data from a nationally representative survey of children in the U.S. child welfare system, the National Survey of Child and Adolescent Well-Being II, to assess whether young CWS-supervised children (N=1,652) who were enrolled in ECE had better language development outcomes 18 months later than those not enrolled in ECE. We also explore whether the type of maltreatment that brought children to the CWS' attention moderates the relationship between ECE and children's language development. After controlling for children's initial scores on the Preschool Language Scale (PLS-3), type(s) of maltreatment experienced, and child and caregiver demographics, we found that ECE participation predicted better PLS-3 scores at follow-up, with a positive interaction between ECE participation and supervisory neglect. ECE seems to be beneficial for CWS-involved children's early language development, especially for children referred to the CWS because they lack appropriate parent supervision at home.

Aim The purpose of this study was to assess the attitude of family physicians toward a child with delayed growth and development. Primary healthcare professionals play a key role in monitoring growth and development, the best indicator of the child's health status. If delayed growth and development can be detected early, then it is usually possible to restore functioning. This descriptive study was performed in Samsun, Turkey, in May and June 2015. In total, 325 family physicians were included. The study consisted of two parts. In the first session of the research, the story of an 18-month-old child with delayed growth and development was presented using visual materials. An interview between the child's mother and a member of primary healthcare staff was then enacted by two of the authors using role-playing. Subsequently, participants were given the opportunity to ask the mother and member of primary healthcare staff questions about the case. During the sessions, two observers observed the participants, took notes and compared these after the presentation. In the second part of the study, the participants were asked to complete a questionnaire consisting of three open-ended questions. Findings When asking questions of the mother, family physicians generally used accusatory and judgmental language. One of the questions most commonly put to the mother was 'Do you think you are a good mother?' Family physicians were keen to provide instruction for the patient and relatives. Family physicians to a large extent thought that the problem of a child with delayed growth and development can be resolved through education. Family physicians' manner of establishing relations with the patient and relatives is inappropriate. We therefore think that they should receive on-going in-service training on the subject.

Language development is one of the most significant processes of early childhood development. Children with delayed speech development are more at risk of acquiring other cognitive, social-emotional, and school-related problems. Music therapy appears to facilitate speech development in children, even within a short period of time. The aim of this pilot study is to explore the effects of music therapy in children with delayed speech development. A total of 18 children aged 3.5 to 6 years with delayed speech development took part in this observational study in which music therapy and no treatment were compared to demonstrate effectiveness. Individual music therapy was provided on an outpatient basis. An ABAB reversal design with alternations between music therapy and no treatment with an interval of approximately eight weeks between the blocks was chosen. Before and after each study period, a speech development test, a non-verbal intelligence test for children, and music therapy assessment scales were used to evaluate the speech development of the children. Compared to the baseline, we found a positive development in the study group after receiving music therapy. Both phonological capacity and the children's understanding of speech increased under treatment, as well as their cognitive structures, action patterns, and level of intelligence. Throughout the study period, developmental age converged with their biological age. Ratings according to the Nordoff-Robbins scales showed clinically significant changes in the children, namely in the areas of client-therapist relationship and communication. This study suggests that music therapy may have a measurable effect on the speech development of children through the treatment's interactions with fundamental aspects of speech development, including the ability to form and maintain relationships and prosodic abilities. Thus, music therapy may provide a basic and supportive therapy for children with delayed speech development. Further studies should be conducted to investigate the mechanisms of these interactions in greater depth. The trial is registered in the German clinical trials register; Trial-No.: DRKS00000343.

2014-05-01
To describe the natural history of Sanfilippo syndrome type A. We performed a retrospective review of 46 children (21 boys, 25 girls) with Sanfilippo syndrome type A evaluated between January 2000 and April 2013. Assessments included neurodevelopmental evaluations, audiologic testing, and assessment of growth, adaptive behavior, cognitive behavior, motor function, and speech/language skills. Only the baseline evaluation was included for patients who received hematopoietic stem cell transplantation. Median age at diagnosis was 35 months, with a median delay between initial symptoms to diagnosis of 24 months. The most common initial symptoms were speech/language delay (48%), dysmorphology (22%), and hearing loss (20%). Early behavioral problems included perseverative chewing and difficulty with toilet training. All children developed sleep difficulties and behavioral changes (e.g., hyperactivity, aggression). More than 93% of the children experienced somatic symptoms such as hepatomegaly (67%), abnormal dentition (39%), enlarged tongue (37%), coarse facial features (76%), and protuberant abdomen (43%). Kaplan-Meier analysis showed a 60% probability of surviving past 17 years of age. Sanfilippo type A is characterized by severe hearing loss and speech delay, followed by a rapid decline in cognitive skills by 3 years of age. Significant somatic disease occurs in more than half of patients. Behavioral difficulties presented between 2 and 4 years of age during a rapid period of cognitive decline. Gross motor abilities are maintained during this period, which results in an active child with impaired cognition. Sleep difficulties are concurrent with the period of cognitive degeneration. There is currently an unacceptable delay in diagnosis, highlighting the need to increase awareness of this disease among clinicians.

Background: Previous studies have reported that children score better in language tasks using sung rather than spoken stimuli. We examined word detection ease in sung and spoken sentences that were equated for phoneme duration and pitch variations in children aged 7 to 12 years with typical language development (TLD) as well as in children with specific language impairment (SLI ), and hypothesized that the facilitation effect would vary with language abilities. Method: In Experiment 1, 69 children with TLD (7–10 years old) detected words in sentences that were spoken, sung on pitches extracted from speech, and sung on original scores. In Experiment 2, we added a natural speech rate condition and tested 68 children with TLD (7–12 years old). In Experiment 3, 16 children with SLI and 16 age-matched children with TLD were tested in all four conditions. Results: In both TLD groups, older children scored better than the younger ones. The matched TLD group scored higher than the SLI group who scored at the level of the younger children with TLD . None of the experiments showed a facilitation effect of sung over spoken stimuli. Conclusions: Word detection abilities improved with age in both TLD and SLI groups. Our findings are compatible with the hypothesis of delayed language abilities in children with SLI , and are discussed in light of the role of durational prosodic cues in words detection.

Early intervention in hearing-impaired children may improve language outcomes and subsequent school and occupational performance. The objective of this study was to retrospectively analyze over 6 years the educational outcome and language development of a first cohort of children, detected by the Flemish universal newborn hearing screening (UNHS) program based on automated auditory brainstem response (AABR), with the oldest children being in primary school. We studied 229 hearing-impaired children from 1998 till 2003. The following variables were considered: the age during the school year 2005-2006, the degree of hearing loss, additional impairments including presence of intellectual disability, school placement and early intervention. Analysis showed that 85.4% of the children with moderate, severe or profound hearing loss and no additional disability, older than 5.5 years, reach mainstream education. Further detailed description was provided for the outcomes of children with uni- and bilateral cochlear implants. Overall results stress that 46% of all children with a cochlear implant obtain mainstream education. Of all cochlear implant (CI) children above 5.5 years, without additional handicaps, 78.9% of children attend primary mainstream school. Data on language development show that up to 45% of the children with unilateral cochlear implant and no additional disabilities had normal to slight delay on language development. These data are fulfilling the goals stated by the JCIH and the American Academy of Pediatrics (AAP) in 2000. The role and impact of additional handicaps is discussed. The importance of early hearing loss identification and hearing therapy for appropriate language development is highlighted. Finally our preliminary results on children with bilateral cochlear implants without additional handicaps present an improved language development in comparison to unilateral CI-children. A vast majority of the children detected by the UNHS program, with moderate, severe or profound hearing loss and no additional disability, older than 5.5 years, reach mainstream education. Additional disabilities have a major influence.

We present findings from a study that focused on specific executive functions (EF) in children with and without specific language impairment (SLI). We analyzed performance patterns and EF profiles (spatial working memory, inhibition control, and sustained attention) in school-age SLI children and two control groups: age-matched and language matched. Our main research goal was to identify those EFs that show a weakness in children with SLI. Our specific aims were to: (1) examine whether the EF problems in children with SLI are domain-general; (2) examine whether deficits in EF in children with SLI can be explained by the general slowness hypothesis or by an overall delay in development; (3) compare EF profiles to examine whether children with SLI show a distinct pattern of performance from their peers. Our findings showed different EF profiles for the groups. We observed differences in performance patterns related to age (e.g., reaction time in response inhibition) and differences related to language status (e.g., sensitivity to interference). The findings show interesting associations in EFs that play a crucial role in language processing. PMID:25302062

Implications of the Java language on computer-based patient records.
Pollard, D; Kucharz, E; Hammond, W E
1996-01-01
The growth of the utilization of the World Wide Web (WWW) as a medium for the delivery of computer-based patient records (CBPR) has created a new paradigm in which clinical information may be delivered. Until recently the authoring tools and environment for application development on the WWW have been limited to Hyper Text Markup Language (HTML) utilizing common gateway interface scripts. While, at times, this provides an effective medium for the delivery of CBPR, it is a less than optimal solution. The server-centric dynamics and low levels of interactivity do not provide for a robust application which is required in a clinical environment. The emergence of Sun Microsystems' Java language is a solution to the problem. In this paper we examine the Java language and its implications to the CBPR. A quantitative and qualitative assessment was performed. The Java environment is compared to HTML and Telnet CBPR environments. Qualitative comparisons include level of interactivity, server load, client load, ease of use, and application capabilities. Quantitative comparisons include data transfer time delays. The Java language has demonstrated promise for delivering CBPRs.

Although early object exploration is considered a key ability for subsequent achievements, very few studies have analyzed its development in extremely low gestational age infants (ELGA- GA <28 weeks), whose early motor skills are delayed. Moreover, no studies have examined its developmental relationship with cognitive and language skills. The present study examined developmental change in Motor Object Exploration (MOE) and different types of MOE (Holding, Oral, Manual and Manual Rhythmic Exploration) in 20 ELGA and 20 full term (FT) infants observed during mother-infant play interaction at 6 and 9 months. It also explored whether specific types of MOE were longitudinally related to 24-month language and cognitive abilities (GMDS-R scores). ELGA infants increased MOE duration from 6 to 9 months, eliminating the initial difference with FT infants. In addition, ELGA infants showed a different pattern of Oral Exploration, that did not increase at 6 months and decrease at 9 months. Oral and Manual Exploration durations at 6 months were longitudinally related to 24-month GMDS-R language and cognitive performance scores respectively. We discuss the relevance of assessing early exploratory abilities in ELGA infants in order to implement customized intervention programs for supporting the development of these skills.

Check-list for the assessment of functional impairment in children with congenital aural atresia.
Montino, Silvia; Agostinelli, Anna; Trevisi, Patrizia; Martini, Alessandro; Ghiselli, Sara
2017-11-01
Congenital Aural Atresia (CAA) is a deformity of the external ear and it is commonly associated with malformations of middle and inner ear and, in some cases, with other facial deformities. Very few assessment measures exist for evaluating the functional impairment in children with CAA. Purpose of this study is to introduce and describe an assessment Checklist, (nominated FOS Checklist) that covers feeding abilities (F), oralmotor skills (O), communication/language development (S) in children with CAA. FOS wants to offer a range of assessment providing a profile of the child in comparison to hearing peers and it aims to make clinicians able to identify additional problems and areas of difficulties as well as specific abilities and skills. Secondary, we want to investigate the presence of correlations between disorders and side of CAA. a new Checklist (FOS Checklist) was administered to 68 children with CAA. Feeding abilities are age-adequate in 94,3% of all patients. 54,4% of all patients are in need for further assessment of their oral-motor skills; delays in language development were found in 44,1% of cases. Orofacial development delays have been observed in 57.2% of subjects among the bilateral CAA group, in 53.9% among the right CAA group and in 53.4% among the left CAA group. Patients referred for further language evaluation were 42,9% in the bilateral CAA group, 33.3% in the right CAA group and 33.3% in the left CAA group. According to the χ 2 analysis, referral for further assessment is independent from side of aural atresia. Subjects with bilateral CAA are more likely to be referred for further assessment, both for oral motor aspects and for speech perception and language development. However, there is not a significant statistical difference between the performances of children with bilateral or unilateral CAA. FOS Checklist is simple, reliable and time effective and can be used in everyday clinical practice. FOS enable clinicians to identify additional problems and areas of difficulties as well as specific abilities and skills; moreover, FOS allows to determine appropriate referrals and intervention strategies.

Male infants are more prone to health problems and developmental delays than female infants. On the basis of theories of gender differences in brain development and social relationships, we explored associations between testosterone and cortisol levels with infant cognitive, motor, and language development ("infant development") in very low birth weight (VLBW) infants, controlling for mother-infant interactions, characteristics of mothers and infants, and days of saliva collection after birth. A total of 62 mother-VLBW infant pairs were recruited from the newborn intensive care unit of a tertiary medical center in the Southeast United States. Data were collected through infant medical record review, biochemical measurement, observation of mother-infant interactions, and standard questionnaires. Infant development was assessed at 6 months corrected age (CA), and mother-infant interactions were observed at 3 and 6 months CA. General linear regression with separate analyses for each infant gender showed that high testosterone levels were positively associated with language development of male infants after controlling for mother-infant interactions and other covariates, whereas high cortisol levels were negatively associated with motor development of female infants after controlling for mother-infant interactions. Steroid hormonal levels may well be more fundamental factors for assessing infant development than infant gender or mother-infant interactions at 6 months CA.

Autism and Bilingualism: A Qualitative Interview Study of Parents' Perspectives and Experiences.
Hampton, Sarah; Rabagliati, Hugh; Sorace, Antonella; Fletcher-Watson, Sue
2017-02-01
Research into how bilingual parents of children with autism spectrum disorder (ASD) make choices about their children's language environment is scarce. This study aimed to explore this issue, focusing on understanding how bilingual parents of children with ASD may make different language exposure choices compared with bilingual parents of children without ASD. Semistructured qualitative interviews were conducted with 17 bilingual parents with a child with ASD and 18 bilingual parents with a typically developing (TD) child. Thematic analysis revealed that, in contrast to parents of TD children, parents with a child with ASD expressed concerns that a bilingual environment would cause confusion for their child and exacerbate language delays. This was particularly common for parents of children with lower verbal ability. Parents also identified potential benefits of bilingualism, particularly in terms of maintaining a close and affectionate bond with their child. Parents of children with ASD have concerns about bilingualism not present for parents of TD children, and these concerns are greater for parents of children with lower verbal ability. Future research in this area should take into account factors such as parent-child bonds as well as communication and language development.

Ventriculomegaly (VM) is the most common central nervous system abnormality diagnosed antenatally, and is associated with developmental delay in childhood. We tested the hypothesis that antenatally diagnosed isolated VM represents a biological marker for altered white matter (WM) and cortical grey matter (GM) development in neonates. 25 controls and 21 neonates with antenatally diagnosed isolated VM had magnetic resonance imaging at 41.97(± 2.94) and 45.34(± 2.14) weeks respectively. T2-weighted scans were segmented for volumetric analyses of the lateral ventricles, WM and cortical GM. Diffusion tensor imaging (DTI) measures were assessed using voxel-wise methods in WM and cortical GM; comparisons were made between cohorts. Ventricular and cortical GM volumes were increased, and WM relative volume was reduced in the VM group. Regional decreases in fractional anisotropy (FA) and increases in mean diffusivity (MD) were demonstrated in WM of the VM group compared to controls. No differences in cortical DTI metrics were observed. At 2 years, neurodevelopmental delays, especially in language, were observed in 6/12 cases in the VM cohort. WM alterations in isolated VM cases may be consistent with abnormal development of WM tracts involved in language and cognition. Alterations in WM FA and MD may represent neural correlates for later neurodevelopmental deficits.

Development of a Spanish-Language Hospice Video.
Chung, Kyusuk; Augustin, Frankline; Esparza, Salvador
2017-09-01
The nation faces a persistent issue of delayed access to hospice care. Even though hospice enrollment is considered to be one of the most difficult medical decisions, physician clinics and hospitals lack tools for helping patients/families faced with making decisions about enrollment. Health-care literature lacks discussion of development of decision-making aids in the context of hospice decisions for minority ethnic groups, even though those groups have decisional needs that may differ from those of non-Hispanic whites. To fill the gap, we developed a video of a Latino hospice patient with footages showing how the patient was being taken care of by her family with support from a hospice disciplinary team. A primary objective of this article is to describe how focus groups, existing decision aids, and individual interviews were used to develop and improve a Spanish-language hospice educational video targeting Latino subgroups with linguistic, cultural, and educational barriers. These steps may provide guidelines for developing and revising health-related videos targeting other minority ethnic groups.

This study investigated listeners' perception of the speech naturalness of people who stutter (PWS) speaking under delayed auditory feedback (DAF) with particular attention for possible listener differences. Three panels of judges consisting of 14 stuttering individuals, 14 speech language pathologists, and 14 naive listeners rated the naturalness of speech samples of stuttering and non-stuttering individuals using a 9-point interval scale. Results clearly indicate that these three groups evaluate naturalness differently. Naive listeners appear to be more severe in their judgements than speech language pathologists and stuttering listeners, and speech language pathologists are apparently more severe than PWS. The three listener groups showed similar trends with respect to the relationship between speech naturalness and speech rate. Results of all three indicated that for PWS, the slower a speaker's rate was, the less natural speech was judged to sound. The three listener groups also showed similar trends with regard to naturalness of the stuttering versus the non-stuttering individuals. All three panels considered the speech of the non-stuttering participants more natural. The reader will be able to: (1) discuss the speech naturalness of people who stutter speaking under delayed auditory feedback, (2) discuss listener differences about the naturalness of people who stutter speaking under delayed auditory feedback, and (3) discuss the importance of speech rate for the naturalness of speech.

The International Shopping List Test (ISLT) is a measure of verbal learning and memory, developed specifically for use in people from different cultural and linguistic backgrounds. In this report, we describe two studies that examined the ISLT's ability to detect memory impairment and memory decline in patients with mild Alzheimer's disease (AD) from a range of cultural and linguistic backgrounds. In Study 1, the performance of Australian-English-speaking adults with mild AD was compared with that of native Australian-English- and Korean-speaking patients with mild AD. Compared with controls, patients with AD from both language groups showed large but equivalent impairments in total recall, delayed recall, rate of learning, and primacy and retention-weighted recall (RWR) measures on the ISLT. In Study 2, the rate of deterioration in verbal memory over 1 year was examined in groups of native Canadian-English, French, and Korean speakers with mild AD using the total recall, delayed recall, and RWR measures. Rates of change on all three measures were equivalent across the language groups, although the magnitude of deterioration was most pronounced for the total recall and RWR measures. Taken together, these results suggest that the ISLT is valid and reliable for the assessment of verbal learning and memory impairment and decline in patients with mild AD from diverse language groups.

Deafness affects ∼2 in 1000 children and is one of the most common congenital impairments. Permanent hearing loss can be treated by fitting hearing aids. More severe to profound deafness is an indication for cochlear implantation. Although newborn hearing screening programs have increased the identification of asymmetric hearing loss, parents and caregivers of children with single-sided deafness are often hesitant to pursue therapy for the deaf ear. Delayed intervention has consequences for recovery of hearing. It has long been reported that asymmetric hearing loss/single-sided deafness compromises speech and language development and educational outcomes in children. Recent studies in animal models of deafness and in children consistently show evidence of an "aural preference syndrome" in which single-sided deafness in early childhood reorganizes the developing auditory pathways toward the hearing ear, with weaker central representation of the deaf ear. Delayed therapy consequently compromises benefit for the deaf ear, with slow rates of improvement measured over time. Therefore, asymmetric hearing needs early identification and intervention. Providing early effective stimulation in both ears through appropriate fitting of auditory prostheses, including hearing aids and cochlear implants, within a sensitive period in development has a cardinal role for securing the function of the impaired ear and for restoring binaural/spatial hearing. The impacts of asymmetric hearing loss on the developing auditory system and on spoken language development have often been underestimated. Thus, the traditional minimalist approach to clinical management aimed at 1 functional ear should be modified on the basis of current evidence. Copyright © 2015 by the American Academy of Pediatrics.

Williams syndrome (WS) is a rare genetic disorder characterized by heart disease, failure to thrive, hearing loss, intellectual or learning disability, speech and language delay, gregariousness, and non-social anxiety. The WS psycholinguistic profile is complex, including relative strengths in concrete vocabulary, phonological processing, and verbal short-term memory and relative weaknesses in relational/conceptual language, reading comprehension, and pragmatics. Many children evidence difficulties with finiteness marking and complex grammatical constructions. Speech-language intervention, support, and advocacy are crucial. PMID:22754603

Language Growth in English Monolingual and Spanish-English Bilingual Children from 2.5 to 5 Years.
Hoff, Erika; Ribot, Krystal M
2017-11-01
To describe the trajectories of English and Spanish language growth in typically developing children from bilingual homes and compare those with the trajectories of English growth in children from monolingual homes, to assess effects of dual language exposure on language growth in typically developing children. Expressive vocabularies were assessed at 6-month intervals from age 30 to 60 months, in English for monolinguals and English and Spanish for bilinguals. Use of English and Spanish in the home was assessed via parental report. Multilevel modeling, including parent education as a covariate, revealed that children from bilingual homes lagged 6 months to 1 year behind monolingual children in English vocabulary growth. The size of the lag was related to the relative amount of English use in the home, but the relation was not linear. Increments in English use conferred the greatest benefit most among homes with already high levels of English use. These homes also were likely to have 1 parent who was a native English speaker. Bilingual children showed stronger growth in English than in Spanish. Bilingual children can lag 6 months to 1 year behind monolingual children in normal English language development. Such lags may not necessarily signify clinically relevant delay if parents report that children also have skills in the home language. Shorter lags are associated with 2 correlated factors: more English exposure and more exposure from native English speakers. Early exposure to Spanish in the home does not guarantee acquisition of Spanish. Copyright © 2017 Elsevier Inc. All rights reserved.

Significant Sleep Dysregulation in a Toddler With Developmental Delay.
Stein, Martin T; Owens, Judith; Abbott, Myles
Derrick's parents made an appointment with a new pediatrician for a second opinion about disordered sleep. Now 22-months old, he was evaluated at 18 months of age for developmental delay when he was found to have "a regulatory disorder associated with delays in language and motor development, hypotonia and significant sleep problems." The parents are now most concerned about his sleeping pattern. Prolonged sleep onset and frequent night awaking occur each night since 6-months of age. These problems are more severe in the past few months when he awakes screaming and cannot be settled. The awakening episodes occur 2 to 4 times each night when "he screams and thrashes his body for up to an hour." Daytime tantrums increased. After the parents read a book about sleep in young children, they provided a calm atmosphere at bedtime including a dark room and singing a quiet lullaby. When these changes did not alter sleep, they purchased a vibrating mattress which was also unsuccessful.Derrick was born full term after an uncomplicated prenatal and perinatal course. He sat at 10 months, crawled at 12 months, and walked at 18 months. He currently drinks from a sippy cup and he can use a utensil to eat. He has few words saying only "no" and "mama" in the past month. Imitation of some words occurred recently. He has responded to simple directions in the past 2 months. Derrick passed the newborn audiology screen. He does not have difficulty swallowing and he does not drool. He plays with many different toys and he plays in parallel with his older brother who also experienced delays in motor and language development. His brother is now doing very well in school. There is no family history of cognitive delay, seizure disorder, cerebral palsy, early developmental delay (other than the brother) or a significant sleep problem. PHYSICAL EXAMINATION:: head circumference, length and weight (75th percentile). He had mild generalized hypotonia, mild weakness, 2+ symmetrical deep tendon reflexes, and absence of ankle clonus. His gait was slightly wide based, steady, and without a limp. Neither ataxia nor drooling was observed. He was easily engaged in play with the examiner without evidence of irritability. The remainder of the examination was normal.

Interstitial and terminal 6q25 deletions are associated with developmental delays, hypotonia, eye pathologies, craniofacial dysmorphologies, and structural brain anomalies. In most cases, speech and language deficits are not described in detail. We report on a case (Patient 1, age 7 years) with a de novo 6q25.3-qter deletion, 11.1 Mb long and encompassing 108 genes, and a case (Patient 2, age 5 years) with an inherited interstitial 6q25.3 deletion, located within Patient 1's deletion region and 403 kb long, the smallest 6q25 deletion reported to date. Both children have hypotonia, motor speech disorders, and expressive language delays. Patient 1's speech was characterized by childhood apraxia of speech (CAS) and dysarthria. Other findings include developmental delay, ataxic cerebral palsy, optic nerve dysplagia, and atypical brain morphologies regarding the corpus callosum and gyration patterns, a clinical profile that closely matches a previously reported case with a nearly identical deletion. Patient 2 had speech characterized by CAS and typical nonverbal processing abilities. His father, a carrier, had typical speech and language but showed difficulties with complex motor speech and hand motor tasks, similar to other adults with residual signs of CAS. The small deletion in this family contains the IGF2R-AIRN-SLC22A2-SLC22A3 gene cluster, which is associated with imprinting and maternal-specific expression of Igf2R, Slc22a2, and Slc22a3 in mice, whereas imprinting in humans is a polymorphic trait. The shared phenotypes in the two patients might be associated with the deletion of the gene cluster. © 2017 Wiley Periodicals, Inc.

Second Language Processing Shows Increased Native-Like Neural Responses after Months of No Exposure
Morgan-Short, Kara; Finger, Ingrid; Grey, Sarah; Ullman, Michael T.
2012-01-01
Although learning a second language (L2) as an adult is notoriously difficult, research has shown that adults can indeed attain native language-like brain processing and high proficiency levels. However, it is important to then retain what has been attained, even in the absence of continued exposure to the L2—particularly since periods of minimal or no L2 exposure are common. This event-related potential (ERP) study of an artificial language tested performance and neural processing following a substantial period of no exposure. Adults learned to speak and comprehend the artificial language to high proficiency with either explicit, classroom-like, or implicit, immersion-like training, and then underwent several months of no exposure to the language. Surprisingly, proficiency did not decrease during this delay. Instead, it remained unchanged, and there was an increase in native-like neural processing of syntax, as evidenced by several ERP changes—including earlier, more reliable, and more left-lateralized anterior negativities, and more robust P600s, in response to word-order violations. Moreover, both the explicitly and implicitly trained groups showed increased native-like ERP patterns over the delay, indicating that such changes can hold independently of L2 training type. The results demonstrate that substantial periods with no L2 exposure are not necessarily detrimental. Rather, benefits may ensue from such periods of time even when there is no L2 exposure. Interestingly, both before and after the delay the implicitly trained group showed more native-like processing than the explicitly trained group, indicating that type of training also affects the attainment of native-like processing in the brain. Overall, the findings may be largely explained by a combination of forgetting and consolidation in declarative and procedural memory, on which L2 grammar learning appears to depend. The study has a range of implications, and suggests a research program with potentially important consequences for second language acquisition and related fields. PMID:22470434

Late onset canonical babbling: a possible early marker of abnormal development.
Oller, D K; Eilers, R E; Neal, A R; Cobo-Lewis, A B
1998-11-01
By their 10th month of life, typically developing infants produce canonical babbling, which includes the well-formed syllables required for meaningful speech. Research suggests that emerging speech or language-related disorders might be associated with late onset of canonical babbling. Onset of canonical babbling was investigated for 1,536 high-risk infants, at about 10-months corrected age. Parental report by open-ended questionnaire was found to be an efficient method for ascertaining babbling status. Although delays were infrequent, they were often associated with genetic, neurological, anatomical, and/or physiological abnormalities. Over half the cases of late canonical babbling were not, at the time they were discovered associated with prior significant medical diagnoses. Late canonical-babbling onset may be a predictor of later developmental disabilities, including problems in speech, language, and reading.

A recent paper by Bialystok et al in Neuropsychologia (vol. 45, pgs. 459 to 464) suggested that early bilingualism produced a statistically significant 4.1-year delay in onset of memory loss symptoms in older individuals with Alzheimer disease, possibly reflecting an increase in the cognitive reserve of these individuals. That study focused on multilingual elderly patients of whom 90% were immigrants. Our memory clinic, in Montreal Canada, has the advantage of having a large set of individuals who are either multilingual immigrants to Canada, or who are nonimmigrants but raised in both official languages of Canada--French and English. We thus attempted to replicate the above findings using a larger cohort in a different setting. We examined age at diagnosis of Alzheimer disease and age at symptom onset for all unilingual versus multilingual participants, and then for those who were nonimmigrant English/French bilinguals. Overall, we found a small but significant protective effect of more than 2 languages spoken, but we found no significant benefit in bilinguals overall in relation to age at diagnosis or age at symptom onset. However, in the immigrant group, the results mirrored those of Bialystok et al with 2 or more languages delaying the diagnosis of Alzheimer disease by almost 5 years. A trend toward the same effect was also seen in nonimmigrants whose first language was French. In contrast, in nonimmigrants whose first language was English, no such effect was found. These results are discussed in relation to the earlier findings and the theory of cognitive reserve.

The current research examined how Arabic diglossia affects verbal learning memory. Thirty native Arab college students were tested using auditory verbal memory test that was adapted according to the Rey Auditory Verbal Learning Test and developed in three versions: Pure spoken language version (SL), pure standard language version (SA), and phonologically similar version (PS). The result showed that for immediate free-recall, the performances were better for the SL and the PS conditions compared to the SA one. However, for the parts of delayed recall and recognition, the results did not reveal any significant consistent effect of diglossia. Accordingly, it was suggested that diglossia has a significant effect on the storage and short term memory functions but not on long term memory functions. The results were discussed in light of different approaches in the field of bilingual memory.

We describe the clinical and molecular features of a child harboring a novel mutation in SLC6A8 gene in association with a milder phenotype than other creatine transporter (CT1) deficient patients (OMIM 300352) [1-7]. The mutation c.757 G>C p.G253R in exon 4 of SLC6A8 was hemizygous in the child, aged 6 years and 6 months, who showed mild intellectual disability with severe speech and language delay. His carrier mother had borderline intellectual functioning. Although the neurochemical and biochemical parameters were fully consistent with those reported in the literature for subjects with CT1 deficit, in our patient within a general cognitive disability, a discrepancy between nonverbal and verbal skills was observed, confirming the peculiar vulnerability of language development under brain Cr depletion.

Delayed Recall and Working Memory MMSE Domains Predict Delirium following Cardiac Surgery.
Price, Catherine C; Garvan, Cynthia; Hizel, Loren P; Lopez, Marcos G; Billings, Frederic T
2017-01-01
Reduced preoperative cognition is a risk factor for postoperative delirium. The significance for type of preoperative cognitive deficit, however, has yet to be explored and could provide important insights into mechanisms and prediction of delirium. Our goal was to determine if certain cognitive domains from the general cognitive screener, the Mini-Mental State Exam (MMSE), predict delirium after cardiac surgery. Patients completed a preoperative MMSE prior to undergoing elective cardiac surgery. Following surgery, delirium was assessed throughout ICU stay using the Confusion Assessment Method for ICU delirium and the Richmond Agitation and Sedation Scale. Cardiac surgery patients who developed delirium (n = 137) had lower total MMSE scores than patients who did not develop delirium (n = 457). In particular, orientation to place, working memory, delayed recall, and language domain scores were lower. Of these, only the working memory and delayed recall domains predicted delirium in a regression model adjusting for history of chronic obstructive pulmonary disease, age, sex, and duration of cardiopulmonary bypass. For each word not recalled on the three-word delayed recall assessment, the odds of delirium increased by 50%. For each item missed on the working memory index, the odds of delirium increased by 36%. Of the patients who developed delirium, 47% had a primary impairment in memory, 21% in working memory, and 33% in both domains. The area under the receiver operating characteristics curve using only the working memory and delayed recall domains was 0.75, compared to 0.76 for total MMSE score. Delirium risk is greater for individuals with reduced MMSE scores on the delayed recall and working memory domains. Research should address why patients with memory and executive vulnerabilities are more prone to postoperative delirium than those with other cognitive limitations.

The effects of contriving motivating operations (MOs) and script fading on the acquisition of the mand "Where's [object]?" were evaluated in 2 boys with language delays. During each session, trials were alternated in which high-preference items were present (abolishing operation [AO] trials) or missing (establishing operation [EO] trials) from their typical locations. Both participants learned to mand during EO trials and not to mand during AO trials during training. Generalization of manding was demonstrated across novel instructors, stimuli, and settings and maintained 3 to 4 weeks following the intervention.

How does speaking another language reduce the risk of dementia?
Fischer, Corinne E; Schweizer, Tom A
2014-05-01
Recently the question of whether or not bilingualism may protect against the development of Alzheimer's disease (AD) has become a topic of great interest. Previous studies suggest that being bilingual slows the decline in executive control associated with the aging process. Spurred by these positive findings in normal subjects, investigators have tried to determine if being bilingual may be associated with delayed onset of AD. A number of studies collectively suggest that being bilingual may lead to a delay in the diagnosis of AD by as much as 5 years, even when taking into account confounders. Although a recent landmark study provides physical evidence confirming this advantage in AD patients, further work needs to be done to clarify its' neuroanatomical basis.

[Developmental course of patients with Asperger's disorder followed objectively from infancy].
Yoshioka, Mieko; Isaka, Masako
2012-01-01
This follow-up study evaluated cognitive and language development in Asperger's disorder (AD) patients diagnosed at the age of 5 to 6 years, with initial complaints of delays in motor or language development in infancy. We evaluated 12 patients (10 males and 2 females) using two intelligence tests:Kyoto Scale of Psychological Development 2001 (K-scale) for those under 6 years, and WISC-III for those over 5-6 years. The cognitive-adaptive area (C-A) of the former test was compared to the performance IQ (PIQ) of the latter test, and the language-social area (L-S) of the former to verbal IQ (VIQ) of the latter. The mean age at the first examination was 3.2 years (range:2.1-4.6 years), and the average age at follow-up was 7.7 years (range:5.3-12.3 years). The average length of follow-up from the initial visit was 5.6 years (range:3.3-8.6 years). During follow-up, the PIQ, VIQ and full scale DQ or IQ (F-DQ/IQ) improved with age. Average scores of the 12 patients at the first examination and last follow-up evaluated by K-scale were:C-A:70.6 (first) and 84.5 (last), L-S:64.8 (first) and 85.8 (last), and F-DQ:68.5 (first) and 84.8 (last). Compared to those with AD, 12 autistic patients with the Kanner type (10 males and 2 females) who visited our clinic during almost the same period, and belonged to almost the same age group, showed average scores at the first examination and last follow-up of:C-A: 61.9 (first) and43.3 (last), L-S:43.0 (first) and43.4 (last), and F-DQ:60.2 (first) and44.5 (last). From these observations, it is apparent that AD patients also showed language delay during infancy, but they improved rapidly between the ages of 4-6 years. This developmental spurt was not seen in autistic patients with the Kanner type.

Imitation, Objects, Tools, and the Rudiments of Language in Human Ontogeny
Meltzoff, A. N.
2013-01-01
Human beings are imitative generalists. We can immediately imitate a wide range of behaviors with great facility, whether they be vocal maneuvers, body postures, or actions on objects. The ontogeny of this skill has been an enduring question in developmental psychology. Classical theory holds that the ability to imitate facial gestures is a milestone that is passed at about one year. Before this time infants are thought to lack the perceptual-cognitive sophistication necessary to match a gesture they can see with one they cannot see themselves perform. A second developmental milestone is the capacity for deferred imitation, i.e. imitation of an absent model. This is said to emerge at about 18 months, in close synchrony with other higher-order activities such as object permanence and tool use, as part of a general cognitive shift from a purely sensory-motor level of functioning to one that allows language. Research suggests that the imitative capacity of young infants has been underestimated. Human infants are capable of imitating facial gestures at birth, with infants less than one day old manifesting this skill. Moreover recent experiments have established deferred imitation well before the predicted age of 18 months. Studies discussed here show that 9-month-olds can duplicate acts after a delay of 24 hours, and that 14-month-olds can retain and duplicate as many as five actions over a 1-week delay. These new findings re-raise questions about the relation between nonverbal cognitive development and language development: What aspects, if any, of these two domains are linked? A hypothesis is delineated that predicts certain very specific relations between particular cognitive and semantic achievements during the one-word stage, and data are reported supporting this hypothesis. Specifically, relations are reported between: (a) the development of object permanence and the use of words encoding disappearance, (b) means-ends understanding (as manifest in tool use) and words encoding success and failure, and (c) categorization behavior and the onset of the naming explosion. This research on human ontogeny suggests close and highly specific links between aspects of early language and thought. PMID:23997403

Bilingualism is common in South Africa, with many children acquiring isiXhosa as a home language and learning English from a young age in nursery or crèche. IsiXhosa is a local language, part of the Bantu language family, widely spoken in the country. Aims: To describe changes in a bilingual child's speech following intervention based on a theoretically motivated and tailored intervention plan. Methods and procedures: This study describes a female isiXhosa-English bilingual child, named Gcobisa (pseudonym) (chronological age 4 years and 2 months) with a speech sound disorder. Gcobisa's speech was assessed and her difficulties categorised according to Dodd's (2005) diagnostic framework. From this, intervention was planned and the language of intervention was selected. Following intervention, Gcobisa's speech was reassessed. Outcomes and results: Gcobisa's speech was categorised as a consistent phonological delay as she presented with gliding of/l/in both English and isiXhosa, cluster reduction in English and several other age appropriate phonological processes. She was provided with 16 sessions of intervention using a minimal pairs approach, targeting the phonological process of gliding of/l/, which was not considered age appropriate for Gcobisa in isiXhosa when compared to the small set of normative data regarding monolingual isiXhosa development. As a result, the targets and stimuli were in isiXhosa while the main language of instruction was English. This reflects the language mismatch often faced by speech language therapists in South Africa. Gcobisa showed evidence of generalising the target phoneme to English words. Conclusions and implications: The data have theoretical implications regarding bilingual development of isiXhosa-English, as it highlights the ways bilingual development may differ from the monolingual development of this language pair. It adds to the small set of intervention studies investigating the changes in the speech of bilingual children following intervention. In addition, it contributes to the small amount of data gathered regarding typical bilingual acquisition of this language pair.

To avoid disturbed teamwork, unnecessary radiation exposure, and procedural delays, we designed and tested a uniform communication language for use in fluoroscopy-assisted surgical procedures. Input of surgeons and radiographers was used to create a set of commands. The potential benefit of this terminology was explored in an experimental setting. There was a tremendous diversity in the currently used terminology. Use of the newly designed terminology showed a reduction of procedural time and amount of images needed. Our first standardized Dutch language terminology can reduce total fluoroscopy time, number of images acquired, and potentially radiation exposure. For Dutch speaking colleagues, the developed terminology is freely available for use in their OR.

Before the introduction of cochlear implant (CI) in 1980, hearing aids were the only means by which profoundly deaf children had access to auditory stimuli. Nowadays, CI is firmly established as effective option in speech and language rehabilitation of deaf children, but much of the literature regarding outcomes for children after CI are focused on development of speech and less is known about language acquisition. So, the main aim of this study is the evaluation of verbal intelligence quotient (IQ) of cochlear implanted children in comparison with normal children. 30 cochlear implanted and 30 normal hearing children with similar socio-economic level at the same age were compared by a revised version (in Persian) of WISC test (Wechsler, 1991). Then the data were analyzed through SPSS software 16. In spite of the fact that cochlear implanted children did well in different parameters of WISC test, the average scores of this group was less than normal hearing children. But in similarities (one of the parameters of WISC test) 2 group's performance was approximately the same. CI plays an important role in development of verbal IQ and language acquisition of deaf children. Different researches indicate that most of the cochlear implanted children show less language delay during the time. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

We report on a girl who presents with hearing loss, behavioral disturbances (according to the Inventory for Client and Agency Planning) as well as motor and cognitive delay (according to Battelle Developmental Inventories) which have a significant impact on her speech and language abilities [according to the Peabody Picture Vocabulary Test (ed 3), and the Prueba de Lenguaje Oral de Navarra-Revisada (Navarra Oral Language Test, Revised)]. Five copy number variations (CNVs) were identified in the child: arr[hg18] 7q32.1q33(127109685-132492196)×1, 8p23.1(7156900-7359099) ×1, 15q13.1(26215673-26884937)×1, Xp22.33(17245- 102434)×3, and Xp22.33(964441-965024)×3. The pathogenicity of similar CNVs is mostly reported as unknown. The largest deletion is found in a hot spot for cognitive disease and language impairment and contains several genes involved in brain development and function, many of which have been related to developmental disorders encompassing language deficits (dyslexia, speech-sound disorder, and autism). Some of these genes interact with FOXP2 . The proband's phenotype may result from a reduced expression of some of these genes.

Williams syndrome (WS) is a genetic disease with a relatively homogeneous profile: relatively well-preserved language, impaired cognitive activities, and hypersociability. Autism spectrum disorder (ASD) refers to a group of individuals with impairments in aspects of communication and a particular pattern of language acquisition. Although ASD and WS are polar opposites when it comes to communication abilities (language and emotion) and social behavior, comparisons between WS and ASD are still rare in the literature. ASD and WS are both associated with general language and developmental delays. Difficulties in social interaction and general pragmatic difficulties are reported in both ASD and WS, but are more pervasive in ASD. Regarding facial emotion recognition, the two syndromes differ markedly in sensitivity to human faces. Despite the heterogeneity of these two groups, only a few studies with children have paid sufficient attention to participant recruitment and study design. A number of aspects need to be taken into account (eg, small age range, homogeneity of the subgroups, matching with typically developing children) if scientific results are to inform the design of intervention programs for children with neurodevelopmental disorders such as ASD and WS.

We report on a girl who presents with hearing loss, behavioral disturbances (according to the Inventory for Client and Agency Planning) as well as motor and cognitive delay (according to Battelle Developmental Inventories) which have a significant impact on her speech and language abilities [according to the Peabody Picture Vocabulary Test (ed 3), and the Prueba de Lenguaje Oral de Navarra-Revisada (Navarra Oral Language Test, Revised)]. Five copy number variations (CNVs) were identified in the child: arr[hg18] 7q32.1q33(127109685-132492196)×1, 8p23.1(7156900-7359099) ×1, 15q13.1(26215673-26884937)×1, Xp22.33(17245- 102434)×3, and Xp22.33(964441-965024)×3. The pathogenicity of similar CNVs is mostly reported as unknown. The largest deletion is found in a hot spot for cognitive disease and language impairment and contains several genes involved in brain development and function, many of which have been related to developmental disorders encompassing language deficits (dyslexia, speech-sound disorder, and autism). Some of these genes interact with FOXP2. The proband's phenotype may result from a reduced expression of some of these genes. PMID:27867345

In specific language impairment (SLI), there is a delay in the child's oral language skills when compared with nonverbal cognitive abilities. The problems typically relate to phonological and morphological processing and word learning. This article reviews studies which have used mismatch negativity (MMN) in investigating low-level neural auditory dysfunctions in this disorder. With MMN, it is possible to tap the accuracy of neural sound discrimination and sensory memory functions. These studies have found smaller response amplitudes and longer latencies for speech and non-speech sound changes in children with SLI than in typically developing children, suggesting impaired and slow auditory discrimination in SLI. Furthermore, they suggest shortened sensory memory duration and vulnerability of the sensory memory to masking effects. Importantly, some studies reported associations between MMN parameters and language test measures. In addition, it was found that language intervention can influence the abnormal MMN in children with SLI, enhancing its amplitude. These results suggest that the MMN can shed light on the neural basis of various auditory and memory impairments in SLI, which are likely to influence speech perception. Copyright © 2017.

The number of very low birth weight (VLBW) births is increasing worldwide. Despite better care in recent years, they have a high incidence of delayed growth and development. There are no previous studies regarding the growth and development of these infants at Queen Sirikit National Institute of Child Health (QSNICH). To study growth and developmental outcome of VLBW infants, aged 18-24 months who were discharged from QSNICH. VLBW infants who were discharged from QSNICH during the year 2007 were recruited in the study. Patients with chromosomal abnormalities, major congenital anomalies, definite congenital infections and positive maternal anti-HIV tests were excluded. At the corrected age of 18-24 months, the parents were called upon to bring their infants for complete physical examination and developmental evaluation on 2 occasions, two months apart. There were 111 cases of VLBW infants who were discharged from QSNICH during the year 2007. Fifty-four patients were eligible for the present study. Thirty cases (55.56%) were contacted for the first examination. During this examination, there were 3 cases (10%) with low head circumference, 1 case (3.33%) with poor weight gain, 5 cases (16.67%) with visual defect, 1 case (3.33%) with moderately severe hearing loss, 1 case (3.33%) with cerebral palsy and 7 cases (23.33%) with delayed development. Twenty-one cases could be recalled for a second evaluation. Two of the 5 cases had delayed language development. There were no cases with hydrocephalous, blindness or profound hearing loss. VLBW infants at QSNICH had much better survival during recent years. Most of these survivors had normal growth and development. Those with delayed growth and development need aggressive intervention and long-term follow-up for enhancement of quality of their lives.

To determine whether there is a higher risk for cognitive or language delay among HIV-exposed uninfected (HEU) children exposed to cART (zidovudine/lamivudine/lopinavir/ritonavir) in utero and through 1 year of breast-feeding (World health Organization Option B+), compared with the control children born to HIV-uninfected mothers. This is a double cohort study from Lusaka, Zambia. HEU (n = 97) and control (n = 103) children aged 15-36 months were assessed on their early nonverbal problem-solving and language skills using the standardized Capute Scales. A score of less than 85 on the Capute Full-Scale Developmental Quotient (FSDQ) was considered indicative of developmental delay and was the primary outcome of interest. An FSDQ of less than 85 was found in eight (8.3%) of HEU participants and 15 (14.6%) of controls. In univariate logistic regressions, lower income [odds ratio (OR) = 0.93, P = 0.02], older infant age (OR = 1.08, P = 0.03), lower birth weight (OR = 0.16, P < 0.001), and less maternal education (OR = 0.41, P = 0.047) were associated with the probability of FSDQ less than 85, whereas Group (control/HEU) was not (OR = 1.88, P = 0.16). In the multivariable analysis, only lower birth weight (OR = 0.15, P < 0.001) remained associated with FSDQ less than 85. Our study did not support the presence of an adverse effect on cognitive and language development with prolonged antepartum and postpartum cART e/xposure. Larger studies and studies of older HEU children will be required to confirm these reassuring findings.

Background Little is known about the efficacy of language production treatment in subacute severe nonfluent aphasia. Although Melodic Intonation Therapy (MIT) is a language production treatment for this disorder, until now MIT effect studies have focused on chronic aphasia. Purpose This study examines whether language production treatment with MIT is effective in subacute severe nonfluent aphasia. Methods A multicenter, randomized controlled trial was conducted in a waiting-list control design: patients were randomly allocated to the experimental group (MIT) or the control group (control intervention followed by delayed MIT). In both groups, therapy started at 2 to 3 months poststroke and was given intensively (5 h/wk) during 6 weeks. In a second therapy period, the control group received 6 weeks of intensive MIT. The experimental group resumed their regular treatment. Assessment was done at baseline (T1), after the first intervention period (T2), and after the second intervention period (T3). Efficacy was evaluated at T2. The impact of delaying MIT on therapy outcome was also examined. Results A total of 27 participants were included: n = 16 in the experimental group and n = 11 in the control group. A significant effect in favor of MIT on language repetition was observed for trained items, with mixed results for untrained items. After MIT there was a significant improvement in verbal communication but not after the control intervention. Finally, delaying MIT was related to less improvement in the repetition of trained material. Conclusions In these patients with subacute severe nonfluent aphasia, language production treatment with MIT was effective. Earlier treatment may lead to greater improvement. © The Author(s) 2014.

Introduction This study aims to explore the impact of Parent Participation Program on the development of developmental delay children. Methods Pretest-posttest equivalent-group experimental design study was used in this paper. A total of 30 pairs of developmental delay children aged 0–72 months and their parents participated into this study. They were divided into two groups, namely control group and experimental group, according to parents’ wishes. The objects of study in control group received 16 courses of direct rehabilitation therapy; those in experimental group received 8 courses of direct rehabilitation therapy and 8 courses of instruction and tracking of Parent Participation Program. The duration of the intervention was 8 weeks. All cases should be evaluated before and after the intervention, to analyze the difference before and after intervention and among groups. The statistical methods in this paper included descriptive analysis, Chi-square test, independent sample t-test, pair-sample t-test. Results and conclusion The intervention of Parent Participation Occupational Program has positive impact on the development of developmental delay children in various fields. Among all the intervention results, the progress of the experimental group is 1.895 times more than that of the control group. With parent involvement, Parent Participation Occupational Therapy can promote the cognitive ability, language ability, action ability (gross and fine movement), social competence and self-care ability of children with developmental delay. Finally, the researcher presents suggestions and directions for future research in accordance with the results. PMID:29503546

Evaluative understanding and role-taking ability: a comparison of deaf and hearing children.
Kusché, C A; Greenberg, M T
1983-02-01
The purposes of this study were (1) to evaluate the growth of social-cognitive knowledge in deaf and hearing children during the early and middle school years and (2) to assess the relative importance of language in 2 domains of social cognition. This study separately examined the child's ability to (1) evaluate the concepts of good and bad and (2) take another person's perspective. Subjects consisted of 30 deaf and 30 hearing children divided into 3 developmental levels (52 months, 74 months, and 119 months old). For the good/bad evaluation test, each child was shown 12 sets of multiple-choice pictures. Each set had 4 alternatives, which included 1 good, 1 bad, or all neutral activities. Role-taking ability was evaluated through the child's choice of strategy in a binary-choice hiding/guessing game. The results showed that deaf children evidence a developmental delay in the understanding of the concepts of good and bad. With regard to role-taking ability, there appears to be a developmental delay with young deaf children, which is no longer apparent by the age of 6. The assumption of egocentrism in school-age deaf children frequently found in the literature thus appears to be misleading. It is not that these deaf children are unable to take another person's perspective, but rather that they are delayed in evaluative understanding. The results suggest that language is of varying importance in differing domains of social and personality development.

This paper addressed relations between language, social communication and behaviour, and their trajectories, in a sample of 9-11-year-olds (n=91) who had been referred to clinical services with concerns about language as pre-schoolers. Children were first assessed at 2½-4 years, and again 18 months later. Results revealed increasing differentiation of profiles across time. By 9-11 years, 11% of the sample had social communication deficits, 27% language impairment, 20% both, and 42% neither. The size of group differences on key language and social communication measures was striking (2-3 standard deviations). Social communication deficits included autistic mannerisms and were associated with social, emotional and behavioural difficulties (SEBDs); in contrast, language impairment was associated with hyperactivity only. Children with both language and social communication problems had the most severe difficulties on all measures. These distinct school-age profiles emerged gradually. Investigation of developmental trajectories revealed that the three impaired groups did not differ significantly on language or SEBD measures when the children were first seen. Only low performance on the Early Sociocognitive Battery, a new measure of social responsiveness, joint attention and symbolic understanding, differentiated the children with and without social communication problems at 9-11 years. These findings suggest that some children who first present with language delay or difficulties have undetected Autism Spectrum Disorders which may or may not be accompanied by language impairment in the longer term. This new evidence of developmental trajectories starting in the preschool years throws further light on the nature of social communication and language problems in school-age children, relations between language impairment and SEBDs, and on the nature of early language development.

Autism is a global disorder, but relatively little is known about its presentation and occurrence in many developing countries, including Libya. To estimate the prevalence of autistic spectrum disorders in children referred to Al-Khadra hospital (KH). To increase the awareness among pediatrician and primary health care providers of the importance of considering autism in children presenting with speech and language disorders. Prospective hospital-based study of all children referred to a neurodevelopment clinic between 2005 and 2009 with the diagnosis of either speech and language difficulties or behavioral difficulties. A total of 38,508 children were seen in the pediatric outpatient clinics of KH, Tripoli, between 2005 and 2009. Of these, 180 children were referred to the neurodevelopment clinic with history of delayed speech and language and or behavioral difficulties. A diagnosis of autism was made in 128 children, which gives a prevalence of approximately 1 in 300. The prevalence of autism in Libya is probably similar to that seen in the USA and the UK. No data were available for comparison from either Arab or other developing countries. Autism is an important differential diagnosis of any language disorder 'and behavioral difficulties'.

Language impairment (LI) risk is increased for perinatally acquired human immunodeficiency virus-infected (PHIV) and perinatally exposed to HIV but uninfected (PHEU) youth. This study evaluates the persistence of LI in these groups. The Clinical Evaluation of Language Fundamentals was repeated on participants of the Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol 18 months postbaseline. Regression models identified factors associated with change in standardized score (SC) and the resolution or development of LI. Of 319 participants, 112 had LI at baseline. Upon re-evaluation, SCs were highly stable and changes were similar in PHIV (n = 212) and PHEU (n = 107) participants. Those with family history of language delays had a 2.39 point lower mean increase in SCs than those without, after controlling for demographic and socioeconomic factors and baseline LI status. Among PHIV participants, CD4 count <350 cells/mm 3 was associated with lower mean SC change (4.32 points), and exposure to combination antiretroviral therapy (cART) or protease inhibitors (PIs) was associated with a higher mean SC change (5.93 and 4.19 points, respectively). Initial LI was persistent in most cases (78%); 20 new cases occurred (10%). Female sex was associated with higher odds of LI resolution. Among PHIV, duration and baseline cART and history of PI use were associated with LI resolution; higher percentage of detectable viral loads before baseline was associated with lower odds of resolution. The PHIV and PHEU youth are at risk for persistent LI, and family history of language delays was a risk factor for persistence of problems. Measures of successful HIV treatment predicted more favorable outcomes among PHIV youth. © The Author 2016.

Background Language development is one of the most significant processes of early childhood development. Children with delayed speech development are more at risk of acquiring other cognitive, social-emotional, and school-related problems. Music therapy appears to facilitate speech development in children, even within a short period of time. The aim of this pilot study is to explore the effects of music therapy in children with delayed speech development. Methods A total of 18 children aged 3.5 to 6 years with delayed speech development took part in this observational study in which music therapy and no treatment were compared to demonstrate effectiveness. Individual music therapy was provided on an outpatient basis. An ABAB reversal design with alternations between music therapy and no treatment with an interval of approximately eight weeks between the blocks was chosen. Before and after each study period, a speech development test, a non-verbal intelligence test for children, and music therapy assessment scales were used to evaluate the speech development of the children. Results Compared to the baseline, we found a positive development in the study group after receiving music therapy. Both phonological capacity and the children's understanding of speech increased under treatment, as well as their cognitive structures, action patterns, and level of intelligence. Throughout the study period, developmental age converged with their biological age. Ratings according to the Nordoff-Robbins scales showed clinically significant changes in the children, namely in the areas of client-therapist relationship and communication. Conclusions This study suggests that music therapy may have a measurable effect on the speech development of children through the treatment's interactions with fundamental aspects of speech development, including the ability to form and maintain relationships and prosodic abilities. Thus, music therapy may provide a basic and supportive therapy for children with delayed speech development. Further studies should be conducted to investigate the mechanisms of these interactions in greater depth. Trial registration The trial is registered in the German clinical trials register; Trial-No.: DRKS00000343 PMID:20663139

This study aims to investigate the developmental effects of atypical antipsychotics on infants who were born to mothers taking an atypical antipsychotic throughout pregnancy. The developmental progress of 76 infants who experienced fetal exposure to atypical antipsychotics was compared to that of 76 matched control infants who had no fetal exposure to any antipsychotics. Planned assessment included Apgar score, body weight, height, and the cognitive, language, motor, social-emotional, and adaptive behavior composite scores of the Bayley Scales of Infant and Toddler Development, third edition (BSID-III). Student's t test and Chi-square analysis were used as appropriate. Repeated measurements were evaluated by analysis of covariance. At 2 months of age, the mean composite scores of cognitive, motor, social-emotional, and adaptive behavior of BSID-III were significantly lower in atypical antipsychotic-exposed infants than the controls. More atypical antipsychotic-exposed infants had delayed development in cognitive, motor, social-emotional, and adaptive behavior domains as defined by the composite score of <85 in these subscales of BSID-III. At 12 months of age, there were no significant differences between the two groups in all mean composite scores of BSID-III. More atypical antipsychotic-exposed infants had low birth weight than the controls (13.2 vs. 2.6 %, P = 0.031), although there were no significant difference in mean birth weight and height between the two groups. Fetal exposure to atypical antipsychotics may cause short-term delayed development in cognitive, motor, social-emotional, and adaptive behavior, but not in language, body weight, or height.

We examined the pattern of neuropsychological impairments of children with FASD (compared to controls) on NEPSY-II measures of attention and executive functioning, language, memory, visuospatial processing, and social perception. Participants included 32 children with FASD and 30 typically developing control children, ranging in age from 6 to 16 years. Children were tested on the following subtests of the NEPSY-II: Attention and Executive Functioning (animal sorting, auditory attention/response set, and inhibition), Language (comprehension of instructions and speeded naming), Memory (memory for names/delayed memory for names), Visual-Spatial Processing (arrows), and Social Perception (theory of mind). Groups were compared using MANOVA. Children with FASD were impaired relative to controls on the following subtests: animal sorting, response set, inhibition (naming and switching conditions), comprehension of instructions, speeded naming, and memory for names total and delayed, but group differences were not significant on auditory attention, inhibition (inhibition condition), arrows, and theory of mind. Among the FASD group, IQ scores were not correlated with performance on the NEPSY-II subtests, and there were no significant differences between those with and without comorbid ADHD. The NEPSY-II is an effective and useful tool for measuring a variety of neuropsychological impairments among children with FASD. Children with FASD displayed a pattern of results with impairments (relative to controls) on measures of executive functioning (set shifting, concept formation, and inhibition), language, and memory, and relative strengths on measures of basic attention, visual spatial processing, and social perception.
