Abstract
Cumulating evidence suggests that atypical emotion processing in autism may generalize across different stimulus domains. However, this evidence comes from studies examining explicit emotion recognition. It remains unclear whether domain-general atypicality also applies to implicit emotion processing in autism and its implication for real-world social communication. To investigate this, we employed a novel cross-modal emotional priming task to assess implicit emotion processing of spoken/sung words (primes) through their influence on subsequent emotional judgment of faces/face-like objects (targets). We assessed whether implicit emotional priming differed between 38 autistic and 38 neurotypical individuals across age groups as a function of prime and target type. Results indicated no overall group differences across age groups, prime types, and target types. However, differential, domain-specific developmental patterns emerged for the autism and neurotypical groups. For neurotypical individuals, speech but not song primed the emotional judgment of faces across ages. This speech-orienting tendency was not observed across ages in the autism group, as priming of speech on faces was not seen in autistic adults. These results outline the importance of the delicate weighting between speech- versus song-orientation in implicit emotion processing throughout development, providing more nuanced insights into the emotion processing profile of autistic individuals.

Abstract
Williams syndrome (WS) is a rare genetic syndrome. As with all rare syndromes, obtaining adequately powered sample sizes is a challenge. Here we present legacy data from seven UK labs, enabling the characterisation of cross-sectional and longitudinal developmental trajectories of verbal and non-verbal development in the largest sample of individuals with WS to-date. In Study 1, we report cross-sectional data between N = 102 and N = 209 children and adults with WS on measures of verbal and non-verbal ability. In Study 2, we report longitudinal data from N = 17 to N = 54 children and adults with WS who had been tested on at least three timepoints on these measures. Data support the WS characteristic cognitive profile of stronger verbal than non-verbal ability, and shallow developmental progression for both domains. Both cross-sectional and longitudinal data demonstrate steeper rates of development in the child participants than the adolescent and adults in our sample. Cross-sectional data indicate steeper development in verbal than non-verbal ability, and that individual differences in the discrepancy between verbal and non-verbal ability are largely accounted for by level of intellectual functioning. A diverging developmental discrepancy between verbal and non-verbal ability, whilst marginal, is not mirrored statistically in the longitudinal data. Cross-sectional and longitudinal data are discussed with reference to validating cross-sectional developmental patterns using longitudinal data and the importance of individual differences in understanding developmental progression.

Abstract
Previous research on emotion processing in autism spectrum disorder (ASD) has predominantly focused on human faces and speech prosody, with little attention paid to other domains such as nonhuman faces and music. In addition, emotion processing in different domains was often examined in separate studies, making it challenging to evaluate whether emotion recognition difficulties in ASD generalize across domains and age cohorts. The present study investigated: (i) the recognition of basic emotions (angry, scared, happy, and sad) across four domains (human faces, face-like objects, speech prosody, and song) in 38 autistic and 38 neurotypical (NT) children, adolescents, and adults in a forced-choice labeling task, and (ii) the impact of pitch and visual processing profiles on this ability. Results showed similar recognition accuracy between the ASD and NT groups across age groups for all domains and emotion types, although processing speed was slower in the ASD compared to the NT group. Age-related differences were seen in both groups, which varied by emotion, domain, and performance index. Visual processing style was associated with facial emotion recognition speed and pitch perception ability with auditory emotion recognition in the NT group but not in the ASD group. These findings suggest that autistic individuals may employ different emotion processing strategies compared to NT individuals, and that emotion recognition difficulties as manifested by slower response times may result from a generalized, rather than a domain-specific underlying mechanism that governs emotion recognition processes across domains in ASD.

Abstract
Acquiring language and communication skills is one of the biggest challenges for children with Down syndrome (DS). However, few evidence-based interventions exist to enhance the development of language and communication in this population. Shared book reading (SBR) is well-established as an effective intervention for language and communication development of typically developing children, and evidence of the possible effectiveness of this approach for those at risk of language difficulties is emerging. This paper provides a mini-review of the existing evidence for SBR in relation to language and communication outcomes for young children with DS. A systematic literature search was conducted with the following inclusion criteria: children with DS aged 0-6;11 years, SBR, language or communication outcomes. The results show that interventions which incorporate SBR strategies are associated with improved language and communication outcomes for young children with DS, improved parental sensitivity, and continuing implementation of SBR strategies following intervention instruction. However, evidence is limited in scope, of low quality, including mostly single case studies, with only one study having a control group. We conclude that although SBR may hold promise as a possible intervention, further research is essential to establish what specific components of SBR intervention are most effective for young children with DS and what further adaptations are needed to accommodate the cognitive profile and variability within this population.

Abstract
Research with English-speaking populations has shown that there is a relationship between developmental language disorder (DLD) and emergent literacy skills in children. A small number of Arabic studies have indirectly investigated this relationship in typically developing (TD) children, and children with reading difficulties, and demonstrated the important role of morphosyntactic skills in Arabic reading acquisition. However, none of the previous work has examined the relationship between oral language and emergent literacy skills in children with and without DLD. The aims of this study are twofold: to investigate the language and emergent literacy skills of Saudi Arabic children with DLD aged between 4;0- 6;11 years of age; to compare their performance to age and socioeconomic status matched TD children, and to investigate the relationship between language and emergent literacy skills in both groups. A comprehensive Arabic language and emergent literacy battery was administered. Findings demonstrated that the TD group significantly outperformed the DLD group on most emergent literacy tasks. The DLD group was significantly less accurate than the TD group on syllable segmentation, and phoneme awareness skills. There were significant associations between oral language skills and emergent literacy skills in the DLD group. In the TD group, vocabulary knowledge and syntactic skills were associated with some emergent literacy skills. Syntactic skills were found to have moderately significant relationship with all emergent literacy skills in both groups. This might suggest the important role of morphosyntactic skills to literacy development in Arabic. Overall, findings were consistent with existing literature, and demonstrated strong relationships between oral language and emergent literacy skills in the Arabic language.

Abstract
BACKGROUND Speech and language acquisition can be a challenge for young children with Down syndrome (DS), and while early intervention is important, we do not know what early interventions exist and how effective they may be. AIMS To systematically review existing early speech, language and communication interventions for young children with DS from birth up to 6 years, and to investigate their effectiveness in improving speech, language and communication outcomes in children with DS. Other outcomes are changes in parental behaviour and their responsiveness METHODS & PROCEDURES: We conducted a systematic search of relevant electronic databases to identify early intervention studies targeting speech, language and communication outcomes in children with DS published up to May 2020. A total of 11 studies that met the inclusion criteria were synthesized and appraised for quality using the PEDro-P scale. There were a total of 242 children. We identified three types of intervention: communication training and responsive teaching, early stimulation programme, and dialectic-didactic approach. MAIN CONTRIBUTION The findings from nine out of the 11 studies reported positive outcomes for children's language and communication up to 18 months following the intervention. All nine studies reported interventions that were co-delivered by parents and clinicians. However, there was also a de-accelerated growth in requesting behaviours in the intervention group reported by one study as well as a case of no improvement for the intervention group. Three studies provided some evidence of improvements to parent outcomes, such as increased parental language input and increased responsiveness. However, there was a moderate to high risk of bias for all studies included. CONCLUSIONS The findings from this review suggest that interventions that have high dosage, focus on language and communication training within a naturalistic setting, and are co-delivered by parents and clinicians/researchers may have the potential to provide positive outcomes for children with DS between 0 and 6 years of age. Due to the limited number of studies, limited heterogeneous data and the moderate to high risk of bias across studies, there is an urgent need for higher quality intervention studies in the field to build the evidence base. WHAT THIS PAPER ADDS What is already known on the subject Speech and language acquisition is usually delayed in children with DS, yet there are currently no standard interventions for children under 6. A number of research-based interventions exist in the literature, yet it is unknown how effective these are. What this study adds to existing knowledge This is the first systematic review that specifically and exclusively focuses on parent- and non-parent-mediated speech, language and communication interventions for children with DS between 0 and 6 years of age. It complements three existing recent reviews, each of which has a slightly different focus. The previously published reviews have covered only parent-mediated interventions, excluding interventions not mediated by parents, have reviewed interventions including children and adults, without any mention of what early interventions may be like or how effective these may be for young children with DS, have not always assessed risk of bias or have focused specifically on language interventions excluding those focusing on speech articulation or pre-linguistic skills. The findings from the current review suggest that interventions that have high dosage focus on language and communication training within a naturalistic setting and are co-delivered by parents and clinicians/researchers may have the potential to provide positive outcomes for children with Diwn syndrome from 0 to 6. We acknowledge that the current evidence base comes from studies with moderate to high risk of bias, hence our conclusions are not definitive. What are the potential or actual clinical implications of this work? Speech and language therapists will have synthesized information and a quick reference point on what type of interventions exist for children with DS under the age of 6, and evidence of which intervention approaches may be promising in terms of providing positive outcomes. However, it is acknowledged that, due to the limited number of studies and the moderate to high risk of bias inherent in the evidence, there is an urgent need for higher quality intervention studies in the field to build the evidence base.

Abstract
BACKGROUND Down syndrome is the most common cause of learning disability, affecting approximately 1 in every 700 babies. Children with Down syndrome have particular difficulties with speech and language. This makes it challenging for them to participate fully in life, access healthcare services and educational opportunities. Improving the language skills of young children with Down syndrome is vital for their future social and emotional well-being and behaviour, and consequently contribution to society. As Down syndrome is detected before or at birth, we can provide support from early on. There are currently no standard interventions for improving the language skills of children with Down syndrome under the age of 36 months. Evidence suggests that early parent-based interventions may be effective in improving language outcomes. In partnership with parents and speech and language therapists, we have co-developed an intervention focusing on early social communication skills and our preliminary work shows that it can lead to better language in children with Down syndrome. Our aim is to carry out a feasibility study which will inform a future pilot/full trial to test whether the intervention is effective in improving language skills before children with Down syndrome start school. METHODS This is a two-arm feasibility randomised controlled trial (RCT), with 1:1 randomisation stratified by trial site comparing the intervention (plus standard NHS speech and language therapy) with no intervention (standard NHS speech and language therapy only). We aim to recruit between 25 and 30 children with Down syndrome aged between 11 and 36 months. Sites are defined by the geographical boundaries of three National Health Service (NHS) Trusts. Recruitment is from NHS Speech and Language Therapist caseloads within the 3 Trusts, and self-referral. In the intervention arm, parents/guardians will receive brief training on the parent-based intervention and a manual to follow with their child for 10 weeks. The children's language and early communication skills and family health outcomes will be assessed by a blinded assessor at baseline, post-intervention and 6 month follow-up. Questionnaire and semi-structured interviews will explore the acceptability of the intervention to parents and SLTs. DISCUSSION The feasibility study's outcomes will determine whether it would be viable to progress to a full-trial and whether adjustments need to made to the procedures, data collection methods, intervention delivery and the intensity of support needed. We want to assess whether our early intervention can be delivered and rolled out through NHS Speech and Language Therapy (SLT) Services. We anticipate that NHS SLT Services will need to make ongoing changes due to the COVID-19 pandemic, so it is likely that we will need to make adjustments for the definitive trial. We will also calculate descriptive statistics of the language outcome measure which we will use for any future sample size calculation. TRIAL REGISTRATION ISRCTN13902755.

Abstract
PURPOSE Research on the typical and impaired grammatical acquisition of Arabic is limited. This study systematically examined the morphosyntactic abilities of Arabic-speaking children with and without developmental language disorder (DLD) using a novel sentence repetition task. The usefulness of the task as an indicator of DLD in Arabic was determined. METHOD A LITMUS (Language Impairment Testing in Multilingual Settings) sentence repetition task was developed in Palestinian Arabic (LITMUS-SR-PA-72) and administered to 30 children with DLD (M = 61.50 months, SD = 11.27) and 60 age-matched typically developing (TD) children (M = 63.85 months, SD = 10.16). The task targeted grammatical structures known to be problematic for Arabic-speaking children with DLD (language specific) and children with DLD across languages (language independent). Responses were scored using binary, error, and structural scoring methods. RESULTS Children with DLD scored below TD children on the LITMUS-SR-PA-72, in general, and in the repetition of language-specific and language-independent structures. The frequency of morphosyntactic errors was higher in the DLD group relative to the TD group. Despite the large similarity of the type of morphosyntactic errors between the two groups, some atypical errors were exclusively produced by the DLD group. The three scoring methods showed good diagnostic power in the discrimination between children with DLD and children without DLD. CONCLUSIONS Sentence repetition was an area of difficulty for Palestinian Arabic-speaking children with DLD. The DLD group demonstrated difficulties with language-specific and language-independent structures, particularly complex sentences with noncanonical word order. Most grammatical errors made by the DLD group resembled those of the TD group and were mostly omissions or substitutions of grammatical affixes or omissions of function words. SR appears to hold promise as a good indicator for the presence or absence of DLD in Arabic. Further validation of these findings using population-based studies is warranted.

Abstract
Purpose This study evaluates the effectiveness of a nonword repetition (NWR) task in discriminating between Palestinian Arabic-speaking children with developmental language disorder (DLD) and age-matched typically developing (TD) children. Method Participants were 30 children with DLD aged between 4;0 and 6;10 (years;months) and 60 TD children aged between 4;0 and 6;8 matched on chronological age. The Arabic version of a Quasi-Universal NWR task was administered. The task comprises 30 nonwords that vary in length, presence of consonant clusters (CCs) and wordlikeness ratings. Responses were scored using an item-level scoring method to assess the diagnostic accuracy of the task. Receiver operating characteristic curve analysis was conducted to determine the best cutoff point with the highest sensitivity and specificity values, and likelihood ratios were calculated. Results Children with DLD scored significantly lower on the NWR task than their age-matched TD peers. Only the DLD group was influenced by the phonological complexity of the nonwords, with nonwords with two CC being more difficult than nonwords with no or only one CC. For both groups, three-syllable nonwords were repeated less accurately than two- and one-syllable nonwords. Also, high word-like nonwords were repeated more accurately than nonwords with low wordlikeness ratings. The best cutoff score had sensitivity and specificity of 93% and highly informative likelihood ratios. Conclusions NWR was an area of difficulty for Palestinian Arabic-speaking children with DLD. NWR showed excellent discriminatory power in differentiating Arabic-speaking children diagnosed with DLD from their age-matched TD peers. NWR appears to hold promise for clinical use as it is a useful indicator of DLD in Arabic. These results need to be further validated using population-based studies.

Abstract
Purpose This study investigated the production of tense and subject-verb agreement in Palestinian Arabic-speaking children with developmental language disorder (DLD) in comparison to their typically developing (TD) peers in terms of (a) performance accuracy and (b) error patterns. Method Participants were 14 children with DLD aged 4;0-7;10 and 32 TD children aged 3;0-8;0 matched on nonverbal abilities. Children were asked to complete a picture-based verb elicitation task. The task was designed to measure the production accuracy of tense and subject-verb agreement inflections in Arabic. Results The DLD group scored significantly lower than the TD group on the verb elicitation task. The DLD group was significantly less accurate than the TD group in marking tense, specifically present tense. They were also less accurate in marking agreement in general, with specific difficulty in using feminine verb forms. The DLD and TD groups differed in their tense error patterns, but not in agreement error patterns. Conclusions The acquisition of verb morphology in Palestinian Arabic-speaking children with DLD appears to be delayed and possibly different from their TD peers. The DLD group found the production of marked verb forms more challenging than less marked ones. These results are discussed in light of the structural characteristics of Arabic. Future studies would need to include larger sample sizes; investigate other aspects of verb morphology, including both production and comprehension; include other language domains; and consider longitudinal designs to provide more in-depth knowledge of Arabic language acquisition.

Purpose The study explored longitudinally the course of vocabulary and general language development in a group of infants with Down syndrome (DS) compared to a group of typically developing (TD) infants matched on nonverbal mental ability (NVMA). Method We compared the vocabulary and general language trajectories of the two groups in two ways: (a) at three time points during a 12-month period and (b) at two time points when the groups had made equal progress in NVMA (a period of 6 months for the TD infants vs. 12 months for the infants with DS). Results The TD group had overtaken the DS group on all general language and vocabulary measures by the end of the 12-month period. However, expressive communication and expressive vocabulary were developing at the same rate and level in the two groups when examined over a period in which the two groups were matched in gains in NVMA. Furthermore, the infants with DS showed a receptive language advantage over the TD group; this group's auditory comprehension and receptive vocabulary scores were superior to those of the TD group at both time points when NVMA was accounted for. Conclusion The results shed light on the widely reported discrepancy between expressive and receptive language in individuals with DS. Although infants with DS appear to be developing language skills more slowly than chronological age TD peers, when NVMA is taken into account, infants with DS do not have expressive language delays, and they seem to show a receptive language advantage.

Abstract
A number of studies in different languages have shown that speakers may be sensitive to the presence of inflectional morphology in the absence of verb meaning (Caramazza et al. in Cognition 28(3):297-332, 1988; Clahsen in Behav Brain Sci 22(06):991-1013, 1999; Post et al. in Cognition 109(1):1-17, 2008). In this study, sensitivity to inflectional morphemes was tested in a purposely developed task with English-like nonwords. Native speakers of English were presented with pairs of nonwords and were asked to judge whether the two nonwords in each pair were the same or different. Each pair was composed either of the same nonword repeated twice, or of two slightly different nonwords. The nonwords were created taking advantage of a specific morphophonological property of English, which is that regular inflectional morphemes agree in voicing with the ending of the stem. Using stems ending in /l/, thus, we created: (1) nonwords ending in potential inflectional morphemes, vɔld, (2) nonwords without inflectional morphemes, vɔlt, and (3) a phonological control condition, vɔlb. Our new task endorses some strengths presented in previous work. As in Post et al. (2008) the task accounts for the importance of phonological cues to morphological processing. In addition, as in Caramazza et al. (1988) and contrary to Post et al. (2008), the task never presents bare-stems, making it unlikely that the participants would be aware of the manipulation performed. Our results are in line with Caramazza et al. (1988), Clahsen (1999) and Post et al. (2008), and offer further evidence that morphologically inflected nonwords take longer to be discriminated compared to uninflected nonwords.

Abstract
Down syndrome (DS) is more detrimental to language acquisition compared to other forms of learning disability. It has been shown that early social communication skills are important for language acquisition in the typical population; however few studies have examined the relationship between early social communication and language in DS. The aim of the current study is to compare the relationship between joint attention and concurrent language skills, and maternal interactive style and concurrent language skills in infants with DS and in typically developing (TD) infants matched for mental age. We also investigated if these relationships differ between children with DS and TD children. Twenty-five infants with DS (17-23 months) and 30 TD infants (9-11 months) were assessed on measures of joint attention, maternal interactive style and language. The results indicated a significant positive relationship between responding to joint attention (RJA) and concurrent language for the DS group, and a significant positive relationship between maternal positive expressed emotion (PEEM) and concurrent language for the TD group. We hypothesise that different social-communication factors are associated with language skills in DS, at least between 17 and 23 months of age compared to TD infants of similar non-verbal and general language abilities.

Abstract
The Children's Test of Nonword Repetition (CNRep) is one of the most popular tests of nonword repetition. The test is composed of nonwords of different length, and normative data suggest that children experience more difficulties in repeating long nonwords. An analysis of the distribution of phonological clusters in the test shows that noninitial clusters are unequally distributed in the test: They only appear in long nonwords (four and five syllables). For this reason, we hypothesized that the difficulties children encounter with long nonwords may be influenced by the phonological complexity of the clusters and not just by the challenge for working memory associated with length. To test the hypothesis, we compared repetition performance in long nonwords with and without a noninitial cluster in 18 children with language impairment and 18 typically developing children. The analysis shows that long nonwords with noninitial clusters are repeated less accurately by both groups. In addition, there was an interaction between cluster and age: The effect of cluster is absent in younger children and gradually increases with age. These findings suggest that phonological complexity may be having an impact on the length effect normally observed in the CNRep, and this impact may be particularly evident in older children.

Abstract
PURPOSE Children with Down syndrome (DS) typically have marked delays in language development relative to their general cognitive development, with particular difficulties in expressive compared to receptive language. Although early social communication skills, including gestures and joint attention, have been shown to be related to later language outcomes in DS, knowledge is limited as to whether these factors exclusively predict outcomes, or whether other factors (e.g. perceptual and non-verbal skills) are involved. This study addressed this question. METHOD Longitudinal data for a group of infants with DS (n = 14) and a group of typically-developing (TD) infants (n = 35) were collected on measures that have been shown to predict language in TD infants and/or those with developmental delays. These included: non-verbal mental ability, speech segmentation skills, and early social communication skills (initiating and responding to joint attention, initiating behavioural requests). RESULTS Linear regression analyses showed that speech segmentation and initiating joint attention were the strongest predictors of later language in the TD group, whereas non-verbal mental ability and responding to joint attention were the strongest predictors of later language for infants with DS. CONCLUSIONS Speech segmentation ability may not determine language outcomes in DS, and language acquisition may be more constrained by social communication and general cognitive skills.

Abstract
The aim of the present study was to investigate whether the saliency effect for word beginnings reported in children with dyslexia (Marshall & Van der Lely, 2009) can be found also in typically developing children. Thirty-four typically developing Italian children aged 8-10 years completed two specifically designed tasks: a production task and a perception task. Both tasks used nonwords containing clusters consisting of plosive plus liquid (e.g. pl). Clusters could be either in a stressed or in an unstressed syllable and could be either in initial position (first syllable) or in medial position (second syllable). In the production task, children were asked to repeat the nonwords. In the perception task, the children were asked to discriminate between two nonwords differing in one phoneme belonging to a cluster by reporting whether two repetitions were the same or different. Results from the production task showed that children are more accurate in repeating stressed than unstressed syllables, but there was no difference with respect to position of the cluster. Results from the perception task showed that children performed more accurately when discriminating word initial contrasts than when discriminating word medial contrasts, especially if the cluster was unstressed. Implications of this finding for clinical assessments are discussed.

Abstract
The aim of the article is to provide preliminary data on the use of auxiliaries and clitics in Serbian-speaking children with developmental language impairment. Two groups of children (a group of 30 children with developmental language impairment and a group of 30 typically developing children) aged between 48 and 83 months and matched on IQ took part in the study. They were asked to tell a story from a series of four pictures. The results showed that the children with language impairment omitted significantly more auxiliary verbs and clitics than the controls. In addition, the rate of omission of auxiliaries and clitics did not decrease with increasing chronological age. We conclude that, as in other languages, auxiliary verbs and clitics are particularly difficult for Serbian-speaking children with language impairment.

Abstract
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.

Abstract
This study looks at idiom comprehension by French-speaking people with Williams' syndrome (WS) and metapragmatic knowledge is examined. Idiomatic expressions are a nonliteral form of language where there is a considerable difference between what is said (literal interpretation) and what is meant (idiomatic interpretation). WS is characterized by a relatively preserved formal language, social interest and poor conversational skills. Using this framework, the present study aims to explore the comprehension of idiomatic expressions by 20 participants with WS. Participants performed a story completion task (comprehension task), and a task of metapragmatic knowledge to justify their chosen answers. WS performances were compared to typically developing children with the same verbal mental age. The main results can be summarized as follows: (1) people with WS have difficulties to understand idioms; (2) WS group seems to perform partly as typically developing children for the acquisition of metapragmatic knowledge of linguistic convention: there is a progressive increase in metapragmatic knowledge of linguistic convention as age increased. Our results indicate a delay of acquisition in idiom comprehension in Williams' syndrome.

Abstract
Despite ample research into the language skills of children with specific reading disorder no studies so far have investigated whether there may be a difference between expressive and receptive language skills in this population. Yet, neuro-anatomical models would predict that children who have specific reading disorder which is not associated with movement or attention difficulties, would have lower receptive language skills than expressive. This study investigates the difference between expressive and receptive language skills in a sample of 17 children with specific reading difficulty aged between 7 and 12 years. They were administered a battery of two receptive and two expressive language measures. The results showed that as the neuro-anatomical model would predict, the children scored significantly lower on tests of receptive than on tests of expressive language skills.

Abstract
PURPOSE The authors investigated expressive and receptive intonation abilities in children with Williams syndrome (WS) and the relation of these abilities to other linguistic abilities. METHOD Fourteen children with WS, 14 typically developing children matched to the WS group for receptive language (LA), and 15 typically developing children matched to the WS group for chronological age (CA) were compared on a range of receptive and expressive intonation tasks from the Profiling Elements of Prosodic Systems-Child version (PEPS-C) battery. RESULTS The WS group performed similarly to the LA group on all intonation tasks apart from the long-item imitation task, on which the WS group scored significantly lower than the LA group. When compared with the CA group, the WS group was significantly poorer on all aspects of intonation. Whereas there were a number of significant correlations between the intonation and language measures in the control groups, in the WS group, there was only 1 significant correlation between a PEPS-C task and one of the language measures. CONCLUSION As a result of this study, the authors concluded that children with WS have expressive and receptive intonation abilities as expected for their level of language comprehension and that intonation and other linguistic abilities in WS are not strongly related.

Abstract
The aim of the current study was to investigate expressive affect in children with Williams syndrome (WS) in comparison to typically developing children in an experimental task and in spontaneous speech. Fourteen children with WS, 14 typically developing children matched to the WS group for receptive language (LA) and 15 typically developing children matched to the WS groups for chronological age (CA) were recruited. Affect was investigated using an experimental Output Affect task from the Profiling Elements of Prosodic Systems-Child version (PEPS-C) battery, and by measuring pitch range and vowel durations from a spontaneous speech task. The children were also rated for level of emotional involvement by phonetically naïve listeners. The WS group performed similarly to the LA and CA groups on the Output Affect task. With regard to vowel durations, the WS group was no different from the LA group; however both the WS and the LA groups were found to use significantly longer vowels than the CA group. The WS group differed significantly from both control groups on their range of pitch range and was perceived as being significantly more emotionally involved than the two control groups.

Abstract
BACKGROUND There are anecdotal reports that blind children sometimes use language inappropriately, but there has been no recent systematic investigation of the communication skills of children with congenital blindness. The aim of the present study was to conduct a preliminary investigation of the communication skills of a group of children with congenital blindness. METHODS The parents of eight congenitally blind children completed the Children's Communication Checklist-2. RESULTS The checklist ratings showed that the communication profiles of a large proportion of the group warranted clinical investigation or were indicative of a communication disorder. CONCLUSIONS The results from this preliminary investigation support the need for a larger study on the communication skills of children with congenital blindness.

Abstract
Williams syndrome (WS) is characterized by apparent relative strengths in language, facial processing and social cognition but by profound impairment in spatial cognition, planning and problem solving. Following recent research which suggests that individuals with WS may be less linguistically able than was once thought, in this paper we begin to investigate why and how they may give the impression of linguistic proficiency despite poor standardized test results. This case study of Brendan, a 12-year-old boy with WS, who presents with a considerable lack of linguistic ability, suggests that impressions of linguistic competence may to some extent be the result of conversational strategies which enable him to compensate for various cognitive and linguistic deficits with a considerable degree of success. These conversational strengths are not predicted by his standardized language test results, and provide compelling support for the use of approaches such as Conversation Analysis in the assessment of individuals with communication impairments.

Abstract
This paper investigates whether people with Williams syndrome (WS) have prosodic impairments affecting their expression and comprehension of four main uses of intonation. Two adolescent males with WS were assessed using the PEPS-C battery, which considers prosodic abilities within a psycholinguistic framework, assessing prosodic form and function in both the input and output domains. The performances of the subjects with WS were compared with control data for age and language-comprehension matched children. The results revealed significant prosodic impairment affecting all areas of the profile. Crucially, however, different profiles of strengths and weaknesses were revealed for the two subjects. The results support the growing view that WS is a heterogeneous population in terms of linguistic abilities.

Abstract
Williams syndrome (WS) is a rare genetic disorder resulting from a deletion on chromosome 7. A number of studies have shown that individuals with WS have a superior linguistic profile compared to their non-verbal abilities, however the evidence has been inconclusive, as many studies have disputed such a profile. The vast majority of studies on WS have assumed a single, homogeneous WS linguistic profile in order to support various theoretical viewpoints. The present study investigated the linguistic profiles of 5 individuals with WS on a number of standardized verbal measures and in conversational settings. The results indicated substantially variable performance in all aspects of the verbal domain, which supports the view that WS, linguistically, is a rather heterogeneous condition and this should be taken into consideration when referring to it in theoretical accounts of language acquisition and debates on modularity.

Abstract
BACKGROUND The superiority of language and communication skills in children and adults with Williams syndrome (WS) is currently being debated. Whilst there have been a number of reports of precursors of language in WS in children who have already developed language, there have not been many studies that have prospectively investigated precursors of language in pre-verbal children with WS. AIMS To investigate the development of early social communication skills before the onset of language in WS. METHODS & PROCEDURES A short-term longitudinal single case study was carried out spanning 10 months. The child was assessed five times using parent report, observation of mother-child interactions and by administering the Pre-verbal Communication Schedule, the Pragmatics Profile of Early Communication Skills and the Pre-School Language Scale - 3. OUTCOMES & RESULTS Longitudinal comparisons showed that the level of verbal communication in the child with WS always lagged behind the level of motor and cognitive development. CONCLUSIONS The results indicate that rather than being a strength, social communication was an area of weakness relative to other aspects of development in this case. This case raises the potential desirability for early speech and language assessment and intervention in infants with WS.

Abstract
Approximately 7% of young school-aged children have specific language impairments. Many such children are now being educated in mainstream settings. However, there is a dearth of up-to-date and valid research that considers UK (student) teachers' attitudes towards such children. This study aimed to investigate trainee teachers' attitudes towards teaching children with speech and language impairments, to investigate the reported effects of those attitudes on participants' acceptance of teaching such children, and to consider any implications for speech and language therapy (SLT) services and inclusive education. Nineteen trainee teachers (PGCE students) from a university in the North West of England took part in semistructured group interviews. The data were transcribed and analysed qualitatively, and recurrent themes identified. A range of attitudes was expressed, and six major themes were identified from the data. Participants discussed concerns about the resources and knowledge they considered necessary to support fully children with specific language impairments. There was some differentiation of attitudes related to the types of disability that a child may have and the subject being taught. Much of the discussion was about disabilities in general rather than specific to speech and language impairments. Many of the participants reflected on their own previous experiences to inform their opinions. Although many of the participants expressed positive attitudes, some had concerns about workload and at least one was openly hostile to the idea of teaching children with disabilities within mainstream settings. The implications of these findings are discussed in relation to previous research, the quantitative data obtained in this project, SLT services and the increases in the inclusion of children with specific language impairments into mainstream educational settings.

Abstract
Grammatical performance of individuals with Williams syndrome (WS) has been reported as being unimpaired, despite their comparatively low IQ and poor general cognitive ability. Specific language impairment (SLI) is often seen as the converse of WS, showing poor linguistic ability relative to level of cognitive functioning. Detailed profiles of language functioning in four children with WS and four with SLI are presented which show a much less clear-cut picture than is often portrayed and suggest that children with WS may be less linguistically able than is commonly reported. A comparison of results on standardised tests with performance in real conversations shows that not only the children with SLI but also those with WS have significant linguistic difficulties. This has clear implications for their management by speech and language therapists.
