Abstract
Prevalence of hearing loss in children with autism spectrum disorder (ASD) is uncertain, as it is more challenging to assess hearing function in children with developmental difficulties (DD). We aimed to determine the prevalence and profiles of hearing loss in preschool children with ASD in a Southeast-Asian population who passed newborn hearing screening. A retrospective study of preschool children with DD (ASD, Global Developmental Delay (GDD), and Speech and Language Delay (SLD)) attending the Child Development Unit (CDU) at our hospital was performed. Three hundred and thirty-three children (ASD: n = 129; GDD: n = 110; and SLD: n = 94) underwent hearing assessments. Of these, 10.8% of children (n = 36, comprising 15 with ASD, 12 with GDD and 9 with SLD) had confirmed hearing loss. Hearing loss was predominantly bilateral in children with ASD and GDD; in those with SLD, unilateral and bilateral hearing loss were equally common. Conductive hearing loss occurred as frequently as sensorineural hearing loss in children with ASD and SLD, but was the dominant subtype in those with GDD. Moderate to severe hearing loss (n = 2) was noted only in children with ASD. Children with ASD and GDD required significantly more audiology visits and procedures to obtain conclusive hearing test results, compared to those with SLD. The need to identify hearing loss and monitor for resolution is particularly important in vulnerable populations with communication deficits, such as in those with ASD.

Abstract
PURPOSE This study examines two components of lexical acquisition and phonological development that occur during the first 50-word stage of language development in neurotypical (NT) children. One component is how children learn words based on their existing speech sound inventories (i.e., in-phonology and out-of-phonology word learning). The other component is the relationship between the children's number of words and the number of phonemes in their speech sound inventories. The goal of this study is to determine if the same two components occur in children with autism spectrum disorders (ASDs) who are older than their NT peers but are in the same stage of lexical development. METHOD This study involved 20 minimally verbal children with ASDs, ages 28-72 months, who produced five to 50 spoken words. The children's spoken words were obtained from the MacArthur-Bates Communicative Development Inventories. The speech sound inventories were obtained from the utterances produced during assessment/play sessions with the children. The children's spoken words from the Communicative Development Inventories (CDI) were categorized as either in-phonology or out-of-phonology based on whether the words began with a phoneme in the child's existing speech sound inventory. Additionally, the children's number of spoken words on the CDI was compared to the number of phonemes in their speech sound inventories. RESULTS The children in this study produced in-phonology words more often than out-of-phonology words (z = -3.922; p < .001). Moreover, there was a moderate positive correlation between the children's number of spoken words and the number of phonemes in their speech sound inventories (r = .534, p = .019). CONCLUSIONS The relationship between lexical acquisition and phonological development appears to exist for the children in this study, who are in the first 50-word stage of development. Clinical implications for increasing the expressive language of children with ASDs were discussed.

Abstract
The article aims at presenting the potential of audio description (AD) as an efficient tool to support the speech-language and social-communicative skills of children with developmental disorders. It includes information for both speech therapists and parents on what they may expect from AD, and how they can use it in their everyday work with children. It may also serve as a set of guidelines for AD creators for making their products more effective. The considerations assembled in the article are based on a literature review. Remarks on the possible uses of AD are presented in the context of various problems to be remedied during speech therapy of a child; they range from incorrect articulation of sounds, through hearing problems such as auditory processing disorder, to developmental disabilities, such as autism spectrum disorder (ASD) characterized by difficulties with social interaction and repetitive behaviors including pretending play. The existing evidence proves that audiovisual (AV) materials are an attractive starting point for exercises with a child. Video-modeling, in turn, has proven to be one of the best tools for therapy of individuals with ASD, allowing for better understanding of interpersonal interactions. Therefore, AV materials accompanied with an AD track – which itself is perceived as a tool for enhancing information processing by children – need to demonstrate similar value for mastering communicative competences. AD can be an effective tool in speech therapy. However, to meet the needs of practitioners, caregivers and beneficiaries in a useful manner, it must be prepared with care regarding both its content and form.

Abstract
INTRODUCTION Previous research has explored the overlapping presentation between autism and eating disorders (ED). This study aims to summarize the clinical challenges associated with co-occurring autism and anorexia nervosa (AN) based on clinicians' case notes and minutes from case discussions, to understand how to better support people with the comorbidity. METHOD Thematic analysis was conducted on de-identified notes on 20 cases with AN and autistic characteristics and minutes from case discussions. Themes relevant to clinical challenges in supporting those with the comorbidity were identified, and a thematic map was produced to visually represent the results. RESULTS The key challenges faced by clinicians when treating patients with AN and autism included: communication difficulties, maintaining boundaries, autism screening, presence of other comorbidities, sensory difficulties, atypical presentation of eating difficulties, cognitive rigidity, and emotional difficulties. Adaptations to resolve some of these difficulties included exposure-based food experiments, keeping a record of patients' self-reported communication preferences, individual-level modification of communication style, and providing tools for patients to identify emotions. CONCLUSIONS AND IMPLICATIONS Further exploration to establish the effectiveness of the adaptations is warranted. Furthermore, tools for differentiating between ED, autism and other comorbidities are needed to help clinicians clarify the cause of a presenting symptom, and help them to best support and maintain boundaries with patients.

Abstract
Semantic processing impairments are present in a proportion of individuals with autism spectrum disorder (ASD). Despite the numerous imaging studies investigating this language domain in ASD, there is a lack of consensus regarding the brain structures showing abnormal pattern of activity. This meta-analysis aimed to identify neural activation patterns present during semantic processing in ASD. Findings reveal activation of areas associated with semantic processing and executive functions in ASD. However, the activation was less concise in comparison to controls and there was less activation in the right hemisphere and in areas associated with executive functions. This provides strong support for impaired semantic processing in ASD that is consistently associated with abnormal patterns of neural activity in the semantic network.

Abstract
The last few decades have seen widespread advances in technological means to characterise observable aspects of human behaviour such as gaze or posture. Among others, these developments have also led to significant advances in social robotics. At the same time, however, social robots are still largely evaluated in idealised or laboratory conditions, and it remains unclear whether the technological progress is sufficient to let such robots move “into the wild”. In this paper, we characterise the problems that a social robot in the real world may face, and review the technological state of the art in terms of addressing these. We do this by considering what it would entail to automate the diagnosis of Autism Spectrum Disorder (ASD). Just as for social robotics, ASD diagnosis fundamentally requires the ability to characterise human behaviour from observable aspects. However, therapists provide clear criteria regarding what to look for. As such, ASD diagnosis is a situation that is both relevant to real-world social robotics and comes with clear metrics. Overall, we demonstrate that even with relatively clear therapist-provided criteria and current technological progress, the need to interpret covert behaviour cannot yet be fully addressed. Our discussions have clear implications for ASD diagnosis, but also for social robotics more generally. For ASD diagnosis, we provide a classification of criteria based on whether or not they depend on covert information and highlight present-day possibilities for supporting therapists in diagnosis through technological means. For social robotics, we highlight the fundamental role of covert behaviour, show that the current state-of-the-art is unable to characterise this, and emphasise that future research should tackle this explicitly in realistic settings.

Abstract
Children and adolescents with autism spectrum disorder are thought to be more vulnerable to oral diseases than typically developing individuals due to cariogenic dietary habits, self-injurious behaviors, and increased barriers to dental care services. This review aimed to summarize current evidence comparing the oral health status of people diagnosed with and without autism spectrum disorder. Study selection and screening, data extraction, risk of bias assessment, and quality-of-evidence evaluation was conducted using the Grading of Recommendations Assessment Development and Evaluation approach and performed independently by two reviewers. A total of 16 studies were found eligible for qualitative synthesis and 15 were included in quantitative analysis. When comparing children and adolescents diagnosed with and without autism spectrum disorder, significantly higher prevalence of bruxism was identified. Individuals diagnosed with autism spectrum disorder were also found to have significantly lower salivary pH. However, no statistically significant differences in terms of caries prevalence and severity, oral hygiene and periodontal status, prevalence of malocclusion, dental traumatic injuries, as well as salivary flow rate and buffering capacity were found. The quality of evidence of each outcome was graded as very low mainly due to the overall high risk of bias, considerable heterogeneity, and imprecision. Lay Abstract Children and adolescents diagnosed with Autism Spectrum Disorder (ASD) are thought to be more vulnerable to oral diseases than typically-developing individuals. This is due to their increased barriers to dental care services, self-harm behaviors and dietary habits that may favor tooth decay. In this review, we summarized the current evidence comparing the oral health status of children and adolescents diagnosed with and without ASD. After a systematic search in the literature, we found that the salivary pH of individuals diagnosed with ASD was significantly lower, but the results were not clinically significant that can increase their risks to tooth decay. We also found weak evidence suggesting a higher percentage of children and adolescents diagnosed with ASD having the habit of tooth grinding compared with their neurotypical counterparts. When comparing salivary flow rate, tooth decay, gum diseases, tooth malalignment and tooth trauma; no significant differences were found between the two groups. The findings did not suggest ASD as a predisposing factor to oral diseases: other factors including sugary diet and inadequate oral hygiene may play a more important role. We also call for further research to establish more concrete association between ASD and oral diseases.

Abstract
Children with autism spectrum disorder (ASD) often display impaired listener skills, and few studies have evaluated procedures for establishing initial auditory-visual conditional discrimination skills. We developed and evaluated a treatment package for training initial auditory-visual conditional discriminations based on the extant research on training such discriminations in children with ASD with at least some preexisting skills in this area. The treatment package included (a) conditional-only training, (b) prompting the participant to echo the sample stimulus as a differential observing response, (c) prompting correct selection responses using an identity-match prompt, (d) using progressively delayed prompts, and (e) repeating trials until the participant emitted an independent correct response. Results indicated all participants mastered all listener targets, and the two participants for whom we tested the emergence of corresponding tacts showed mastery of most tacts without direct training. We discuss these results relative to prior research on listener skills and tacts.

Abstract
Alexithymia is a personality construct characterized by altered emotional awareness which has been gaining diagnostic prevalence in a range of neuropsychiatric disorders, with notably high rates of overlap with autism spectrum disorder (ASD). However, the nature of its role in ASD symptomatology remains elusive. Here, we distill research at the intersection of alexithymia and ASD. After a brief synopsis of the studies that plaid a pioneering role in the identification of the overlapping fields between alexithymia and ASD, we comb the literature for evidence of its overlap with ASD in terms of prevalence, etiology, and behaviors. Through a formalized framework of the process of emotional interpretation and expression, we explore evidence for where and how deficits arise in this complex network of events. We portray how these relate to the dynamic interplay between alexithymic and autistic traits and find emerging evidence that alexithymia is both a cause and consequence of autistic behaviors. We end with a strategic proposal for future research and interventions to dampen the impacts of alexithymia in ASD.

Abstract
Phelan-McDermid syndrome (PMS) is a single-locus cause of developmental delay, autism spectrum disorder, and minimal verbal abilities. There is an urgent need to identify objective outcome measures of expressive language for use in this and other minimally verbal populations. One potential tool is an automated language processor called Language ENvironment Analysis (LENA). LENA was used to obtain over 542 h of audio in 18 children with PMS. LENA performance was adequate in a subset of children with PMS, specifically younger children and those with fewer stereotypic vocalizations. One LENA-derived language measure, Vocalization Ratio, had improved accuracy in this sample and may represent a novel expressive language measure for use in severely affected populations.

Abstract
Although language impairment is commonly associated with the autism spectrum disorder (ASD), the Diagnostic Statistical Manual no longer includes language impairment as a necessary component of an ASD diagnosis (American Psychiatric Association, 2013). However, children with ASD and no comorbid intellectual disability struggle with some aspects of language whose precise nature is still outstanding. Narratives have been extensively used as a tool to examine lexical and syntactic abilities, as well as pragmatic skills in children with ASD. This study contributes to this literature by investigating the narrative skills of 30 Greek-speaking children with ASD and normal non-verbal IQ, 16 with language skills in the upper end of the normal range (ASD-HL), and 14 in the lower end of the normal range (ASD-LL). The control group consisted of 15 age-matched typically-developing (TD) children. Narrative performance was measured in terms of both microstructural and macrostructural properties. Microstructural properties included lexical and syntactic measures of complexity such as subordinate vs. coordinate clauses and types of subordinate clauses. Macrostructure was measured in terms of the diversity in the use of internal state terms (ISTs) and story structure complexity, i.e., children's ability to produce important units of information that involve the setting, characters, events, and outcomes of the story, as well as the characters' thoughts and feelings. The findings demonstrate that high language ability and syntactic complexity pattern together in ASD children's narrative performance and that language ability compensates for autistic children's pragmatic deficit associated with the production of Theory of Mind-related ISTs. Nevertheless, both groups of children with ASD (high and low language ability) scored lower than the TD controls in the production of Theory of Mind-unrelated ISTs, modifier clauses and story structure complexity.

Abstract
La evidencia empírica recogida hasta la fecha ofrece argumentos a favor del indudable papel que desempeña la dimensión morfosintáctica del lenguaje en el desarrollo de habilidades de Teoría de la Mente. No obstante, un gran porcentaje de estas investigaciones se ha llevado a cabo con poblaciones de niños con desarrollo típico, por lo que se requieren más estudios que analicen estos aspectos en niños con síndrome de Asperger. El objetivo de este trabajo ha sido examinar el desarrollo morfosintáctico con relación a las habilidades de Teoría de la Mente de un niño Asperger. Se han estudiado además sus habilidades narrativas por ser un factor clave en el desempeño en tareas que implican directamente el desarrollo de capacidades de Teoría de la Mente, adoptándose para ello el método cualitativo de estudio de caso (n=1) con un enfoque interpretativo. Los datos extraídos indican que el mayor número de errores morfosintácticos detectados en este niño se relacionan con la construcción de complementos oracionales y la utilización de pronombres personales. La evaluación de estos aspectos utilizando secuencias narrativas ha permitido averiguar que un gran porcentaje de estos errores se localiza en las tareas que requieren la implicación directa de habilidades de Teoría de la Mente, mientras que las narraciones más ricas y completas se han producido en aquellas historias en las que no se han visto comprometidas estas habilidades.

Abstract
PURPOSE High-functioning autism spectrum disorder (ASD) involves pragmatic impairment of language skills. Among numerous tasks for assessing pragmatic linguistic skills, idioms are important to evaluating high-functioning ASD. Nevertheless, no assessment tool has been developed with specific consideration of Korean culture. Therefore, we designed the Korean Autism Social Language Task (KASLAT) to test idiom comprehension in ASD. The aim of the current study was to introduce this novel psychological tool and evaluate idiom comprehension deficits in high-functioning ASD. MATERIALS AND METHODS The participants included 42 children, ages 6-11 years, who visited our child psychiatric clinic between April 2014 and May 2015. The ASD group comprised 16 children; the attention deficit hyperactivity disorder (ADHD) group consisted of 16 children. An additional 10 normal control children who had not been diagnosed with either disorder participated in this study. Idiom comprehension ability was assessed in these three groups using the KASLAT. RESULTS Both ASD and ADHD groups had significantly lower scores on the matched and mismatched tasks, compared to the normal control children (matched tasks mean score: ASD 11.56, ADHD 11.56, normal control 14.30; mismatched tasks mean score: ASD 6.50, ADHD 4.31, normal control 11.30). However, no significant differences were found in scores of KASLAT between the ADHD and ASD groups. CONCLUSION These findings suggest that children with ASD exhibit greater impairment in idiom comprehension, compared to normal control children. The KASLAT may be useful in evaluating idiom comprehension ability.

Abstract
The development of language, social interaction and communicative skills is remarkably different in the child with autism spectrum disorder (ASD). Atypical brain connectivity has frequently been reported in this patient population. However, the neural correlates underlying their disrupted language development and functioning are still poorly understood. Using resting state fMRI, we investigated the functional connectivity properties of the language network in a group of ASD patients with clear comorbid language impairment (ASD-LI; N = 19) and compared them to the language related connectivity properties of 23 age-matched typically developing children. A verb generation task was used to determine language components commonly active in both groups. Eight joint language components were identified and subsequently used as seeds in a resting state analysis. Interestingly, both the interregional and the seed-based whole brain connectivity analysis showed preserved connectivity between the classical intrahemispheric language centers, Wernicke's and Broca's areas. In contrast however, a marked loss of functional connectivity was found between the right cerebellar region and the supratentorial regulatory language areas. Also, the connectivity between the interhemispheric Broca regions and modulatory control dorsolateral prefrontal region was found to be decreased. This disruption of normal modulatory control and automation function by the cerebellum may underlie the abnormal language function in children with ASD-LI.

Abstract
Reading utilises at least two neural pathways. The temporal lexical route visually maps whole words to their lexical entries, whilst the nonlexical route decodes words phonologically via parietal cortex. Readers typically employ the lexical route for familiar words, but poor comprehension plus precocity at mechanically 'sounding out' words suggests that differences might exist in autism. Combined MEG/EEG recordings of adults with autistic spectrum conditions (ASC) and controls while reading revealed preferential recruitment of temporal areas in controls and additional parietal recruitment in ASC. Furthermore, a lack of differences between semantic word categories was consistent with previous suggestion that people with ASC may lack a 'default' lexical-semantic processing mode. These results are discussed with reference to dual-route models of reading.

Abstract
UNLABELLED We examined the understanding of emotional speech by children and adolescents with autism spectrum disorders (ASD). We predicted that they would have difficulty understanding emotional speech, not because of an emotional prosody processing impairment but because of problems drawing appropriate inferences, especially in multiple-cue environments. Twenty-six children and adolescents with ASD and 26 typically developing controls performed a computerized task featuring emotional prosody, either embedded in a discrepant context or without any context at all. They must identify the speaker's feeling. When the prosody was the sole cue, participants with ASD performed just as well as controls, relying on this cue to infer the speaker's intention. When the prosody was embedded in a discrepant context, both ASD and TD participants exhibited a contextual bias and a negativity bias. However ASD participants relied less on the emotional prosody than the controls when it was positive. We discuss these findings with respect to executive function and intermodal processing. LEARNING OUTCOMES After reading this article, the reader should be able to (1) describe the ASD participants pragmatic impairments, (2) explain why ASD participants did not have an emotional prosody processing impairment, and (3) explain why ASD participants had difficulty inferring the speaker's intention from emotional prosody in a discrepant situation.

Abstract
Acquiring useful language by age 5 has been identified as a strong predictor of positive outcomes in individuals with Autism Spectrum Disorders (ASD). This study examined the relationship between age of language acquisition and later functioning in children with ASD (n = 119). First word acquisition at a range of ages was probed for its relationship to cognitive ability and adaptive behaviors at 52 months. Results indicated that although producing first words predicted better outcome at every age examined, producing first words by 24 months was a particularly strong predictor of better outcomes. This finding suggests that the historic criterion for positive prognosis (i.e., "useful language by age 5") can be updated to a more specific criterion with an earlier developmental time point.

Abstract
Perseveration effects in grasping were examined in two experiments. In both experiments, participants reached and grasped different versions of a novel object with their thumb and forefinger using either a horizontal or vertical pincer grasp. The dependent variable was the choice of grasp. In Experiment 1, trials were performed either with or without visual feedback. In Experiment 2, trials were performed either physically or using motor imagery. In both experiments, participants tended to perseverate in their choice of grip. Further, there was no evidence that either the availability of visual feedback during the preceding or current action modulated this effect; mode of responding was similarly inconsequential. The results were interpreted as evidence for a motor priming explanation of perseveration and against an account that relies on perceptual priming.

Abstract
Several synaptic genes predisposing to autism-spectrum disorder (ASD) have been identified. Nonsense and missense mutations in the SYN1 gene encoding for Synapsin I have been identified in families segregating for idiopathic epilepsy and ASD and genetic mapping analyses have identified variations in the SYN2 gene as significantly contributing to epilepsy predisposition. Synapsins (Syn I/II/III) are a multigene family of synaptic vesicle-associated phosphoproteins playing multiple roles in synaptic development, transmission and plasticity. Lack of SynI and/or SynII triggers a strong epileptic phenotype in mice associated with mild cognitive impairments that are also present in the non-epileptic SynIII(-/-) mice. SynII(-/-) and SynIII(-/-) mice also display schizophrenia-like traits, suggesting that Syns could be involved in the regulation of social behavior. Here, we studied social interaction and novelty, social recognition and social dominance, social transmission of food preference and social memory in groups of male SynI(-/-), SynII(-/-) and SynIII(-/-) mice before and after the appearance of the epileptic phenotype and compared their performances with control mice. We found that deletion of Syn isoforms widely impairs social behaviors and repetitive behaviors, resulting in ASD-related phenotypes. SynI or SynIII deletion altered social behavior, whereas SynII deletion extensively impaired various aspects of social behavior and memory, altered exploration of a novel environment and increased self-grooming. Social impairments of SynI(-/-) and SynII(-/-) mice were evident also before the onset of seizures. The results demonstrate an involvement of Syns in generation of the behavioral traits of ASD and identify Syn knockout mice as a useful experimental model of ASD and epilepsy.

Abstract
In individuals with ASD, difficulties with language comprehension are most evident when higher-level semantic-pragmatic language processing is required, for instance when context has to be used to interpret the meaning of an utterance. Until now, it is unclear at what level of processing and for what type of context these difficulties in language comprehension occur. Therefore, in the current fMRI study, we investigated the neural correlates of the integration of contextual information during auditory language comprehension in 24 adults with ASD and 24 matched control participants. Different levels of context processing were manipulated by using spoken sentences that were correct or contained either a semantic or world knowledge anomaly. Our findings demonstrated significant differences between the groups in inferior frontal cortex that were only present for sentences with a world knowledge anomaly. Relative to the ASD group, the control group showed significantly increased activation in left inferior frontal gyrus (LIFG) for sentences with a world knowledge anomaly compared to correct sentences. This effect possibly indicates reduced integrative capacities of the ASD group. Furthermore, world knowledge anomalies elicited significantly stronger activation in right inferior frontal gyrus (RIFG) in the control group compared to the ASD group. This additional RIFG activation probably reflects revision of the situation model after new, conflicting information. The lack of recruitment of RIFG is possibly related to difficulties with exception handling in the ASD group.

Abstract
PURPOSE To investigate the perception and production of lexical stress and processing of affective prosody in adolescents with high-functioning autism (HFA). We hypothesized preserved processing of lexical and affective prosody but atypical lexical prosody production. METHOD Sixteen children with HFA and 15 typically developing (TD) peers participated in 3 experiments that examined the following: (a) perception of affective prosody (Experiment 1), (b) lexical stress perception (Experiment 2), and (c) lexical stress production (Experiment 3). In Experiment 1, participants labeled sad, happy, and neutral spoken sentences that were low-pass filtered, to eliminate verbal content. In Experiment 2, participants disambiguated word meanings based on lexical stress (HOTdog vs. hot DOG). In Experiment 3, participants produced these words in a sentence completion task. Productions were analyzed with acoustic measures. RESULTS Accuracy levels showed no group differences. Participants with HFA could determine affect from filtered sentences and disambiguate words on the basis of lexical stress. They produced appropriately differentiated lexical stress patterns but demonstrated atypically long productions, indicating reduced ability in natural prosody production. CONCLUSIONS Children with HFA were as capable as their TD peers in receptive tasks of lexical stress and affective prosody. Prosody productions were atypically long, despite accurate differentiation of lexical stress patterns. Future research should use larger samples and spontaneous versus elicited productions.

Abstract
Some higher functioning individuals with autism spectrum disorders (ASDs) are reported to produce perseverative talk, especially around 'special interests'. Topic perseveration is a form of pragmatic impairment captured in Prizant and Rydell's (1993) continuum of unconventional verbal behaviour in autism. Although widely reported, there is little systematic empirical research into this phenomenon. This paper considers the utility of Conversation Analysis in developing knowledge in this area, drawing upon data involving a boy with an ASD interacting with a researcher and a mobile robot platform. Although a frequency analysis of the boy's talk on a single topic may suggest that it is perseverative in nature, in a sequential analysis of both talk and non-spoken activities this study aims to show how these may be interactionally-embedded. It is suggested that, in considering the interactional salience of apparently perseverative talk, it can be useful to explore the participation framework in which the topic is revisited.

Abstract
Previous neuroimaging studies have suggested that children with specific language impairment (SLI) may show subtle anatomical alterations in specific brain regions. We aimed to characterize structural abnormalities in children with SLI using a voxel-wise analysis over the whole brain. Subjects covered a wide age range (5-17 years) in order to assess the dynamic nature of the disorder across childhood. Three-dimensional MRIs were collected from 36 children with SLI and from a comparable group of healthy controls. Global gray and white matter measurements were obtained for each subject, and voxel-based morphometry (VBM) was used to evaluate between-group differences in regional brain anatomy. Possible age-related changes were assessed in separate analyses of younger (below 11 years of age) and older children. SLI patients showed larger global gray and white matter volumes, particularly in the younger subgroup. Voxel-wise analyses of the whole sample showed two regions of increased gray matter volume in SLI: the right perisylvian region and the occipital petalia. Age-group analyses suggested a more extended pattern of volume increases in the younger subjects, which included entorhinal, temporopolar, caudate nucleus, motor-precentral and precuneus gray matter, and white matter of the frontal and temporal lobes. Our results suggest that in the SLI brain there are enduring anatomical alterations that exist across a wide age range, as well as a distributed pattern of abnormalities that appear to normalize with development. They also suggest that the neuroanatomical basis of SLI may be better characterized by considering the dynamic course of the disorder throughout childhood.

Abstract
HCI studies assessing nonverbal individuals (especially those who do not communicate through traditional linguistic means: spoken, written, or sign) are a daunting undertaking. Without the use of directed tasks, interviews, questionnaires, or question-answer sessions, researchers must rely fully upon observation of behavior, and the categorization and quantification of the participant’s actions. This problem is compounded further by the lack of metrics to quantify the behavior of nonverbal subjects in computer-based intervention contexts. We present a set of dependent variables called A3 (pronounced A-Cubed) or Annotation for ASD Analysis, to assess the behavior of this demographic of users, specifically focusing on engagement and vocalization. This paper demonstrates how theory from multiple disciplines can be brought together to create a set of dependent variables, as well as demonstration of these variables, in an experimental context. Through an examination of the existing literature, and a detailed analysis of the current state of computer vision and speech detection, we present how computer automation may be integrated with the A3 guidelines to reduce coding time and potentially increase accuracy. We conclude by presenting how and where these variables can be used in multiple research areas and with varied target populations.

Abstract
BACKGROUND Assessment of 'potential intellectual ability' of children with severe intellectual disability (ID) is limited, as current tests designed for normal children do not maintain their interest. Thus a manual puzzle version of the Raven's Coloured Progressive Matrices (RCPM) was devised to appeal to the attentional and sensory preferences and language limitations of children with ID. It was hypothesized that performance on the book and manual puzzle forms would not differ for typically developing children but that children with ID would perform better on the puzzle form. METHODS The first study assessed the validity of this puzzle form of the RCPM for 76 typically developing children in a test-retest crossover design, with a 3 week interval between tests. A second study tested performance and completion rate for the puzzle form compared to the book form in a sample of 164 children with ID. RESULTS In the first study, no significant difference was found between performance on the puzzle and book forms in typically developing children, irrespective of the order of completion. The second study demonstrated a significantly higher performance and completion rate for the puzzle form compared to the book form in the ID population. CONCLUSION Similar performance on book and puzzle forms of the RCPM by typically developing children suggests that both forms measure the same construct. These findings suggest that the puzzle form does not require greater cognitive ability but demands sensory-motor attention and limits distraction in children with severe ID. Thus, we suggest the puzzle form of the RCPM is a more reliable measure of the non-verbal mentation of children with severe ID than the book form.

Abstract
The aim of this cross-sectional descriptive study was to explore the relation of language proficiency, behavioral difficulties, and development in infants and toddlers. Surveyed were 118 parents/caregivers of preschool children (76 boys, 42 girls). The children were a mean age of 27 months (range, 18-35 months), and 32 (27.1%) had no language delay, 8 (6.8%) had expressive delay, 14 (11.9%) had receptive delay, and 64 (54.2%) had mixed receptive-expressive delay. Children with expressive delay were more likely to have social-emotional problems. Those with receptive delay were more likely to have pervasive developmental problems. Children with receptive-expressive delay were more substantially delayed in all developmental domains; they were more withdrawn and more likely to have pervasive developmental problems. When parents of toddlers report problems, especially behavior problems, a search for delayed language is warranted as these children may be at risk for future social and emotional problems.

Abstract
This study examined the linguistic characteristics of high functioning individuals with autism and Asperger syndrome. Each group consisted of 10 participants who were matched on sex, chronological age, and intelligence scores. Participants generated a narrative after watching a brief video segment of the Social Attribution Task video. Each participant was then asked 10 questions related to the stimulus video. The narrative samples and responses to the questions were analysed linguistically. Individuals with high functioning autism and Asperger syndrome performed similarly on most measures of language function; however, results suggest there may be pragmatically-based differences between the groups in the use of verb tense markers.

Abstract
This study examined executive dysfunction and its relation to language ability in verbal school-age children with autism. Participants were 37 children with autism and 31 nonautistic comparison participants who were matched on age and on verbal and nonverbal IQ but not on language ability, which was lower in the autism group. Children with autism exhibited deficits compared to the comparison group across all 3 domains of executive function that were assessed including working memory (Block Span Backward; Isaacs & Vargha-Khadem, 1989), working memory and inhibitory control (NEPSY Knock-Tap; Korkman, Kirk, & Kemp, 1998), and planning (NEPSY Tower; Korkman et al., 1998). Children with autism were less developed than the comparison group in their language skills, but correlational analyses revealed no specific association between language ability and executive performance in the autism group. In contrast, executive performance was positively correlated with language ability in the comparison group. This pattern of findings suggest that executive dysfunction in autism is not directly related to language impairment per se but rather involves an executive failure to use of language for self-regulation.

Abstract
The psychiatric examination was performed with diagnostic instruments for autism (DSM-IV and Childhood Autism Rating Scale-CARS) in 23 children with Möbius sequence. From the 23 patients studied with Möbius sequence, five (26.1%) met the diagnostic criteria for infantile autism according DSM-IV and two (8.6%), under two years old, showed autistic-like behavior. The scores for six children were compatible to severe autism symptoms according CARS and one child met the criteria for moderate autism symptoms. Among five children with autism, three (60%) had positive history of misoprostol exposure during the first trimester of pregnancy and from two cases autistic-like, one (50%) had positive history of misoprostol exposure during pregnancy. According to our data, this is the first report of Möbius sequence with autism and positive history of misoprostol use during pregnancy.

Abstract
Autism is a complex disorder that is heterogeneous both in its phenotypic expression and its etiology. The search for genes associated with autism and the neurobiological mechanisms that underlie its behavioural symptoms has been hampered by this heterogeneity. Recent studies indicate that within autism, there may be distinct subgroups that can be defined based on differences in neurocognitive profiles. This paper presents evidence for two kinds of subtypes in autism that are defined on the basis of language profiles and on the basis of cognitive profiles. The implications for genetic and neurobiological studies of these subgroups are discussed, with special reference to evidence relating these cognitive phenotypes to volumetric studies of brain size and organization in autism.

Abstract
For decades after Kanner's original paper on the subject was published in 1943, autism was generally considered to be a rare condition with a prevalence of around 2-4 per 10,000 children. Then, studies carried out in the late 1990s and the present century reported annual rises in incidence of autism in pre-school children, based on age of diagnosis, and increases in the age-specific prevalence rates in children. Prevalence rates of up to 60 per 10,000 for autism and even more for the whole autistic spectrum were reported. Reasons for these increases are discussed. They include changes in diagnostic criteria, development of the concept of the wide autistic spectrum, different methods used in studies, growing awareness and knowledge among parents and professional workers and the development of specialist services, as well as the possibility of a true increase in numbers. Various environmental causes for a genuine rise in incidence have been suggested, including the triple vaccine for measles, mumps and rubella (MMR]. Not one of the possible environmental causes, including MMR, has been confirmed by independent scientific investigation, whereas there is strong evidence that complex genetic factors play a major role in etiology. The evidence suggests that the majority, if not all, of the reported rise in incidence and prevalence is due to changes in diagnostic criteria and increasing awareness and recognition of autistic spectrum disorders. Whether there is also a genuine rise in incidence remains an open question.

Abstract
Language regression is observed both in autistic regression and as part of acquired epileptic aphasia (Landau-Kleffner Syndrome). We prospectively identified 177 children with language regression at four major medical centers, and their clinical characteristics were recorded. Their mean age at regression was 22.8 months. The mean time-to-specialist referral was 38 months of age. Most children (88%) met criteria for autism or manifested autistic features. Males (P = 0.02) and children less than 3 years of age who regressed (P = 0.016) had a higher probability of developing autistic behaviors. Seizures were more common in children who regressed after they reached 3 years of age (P < 0.001), and children with seizures were less likely to have associated autistic regression (P < 0.001). Electroencephalogram abnormalities were reported in 37% of patients and were more common in children with seizures (P < 0.001). At last follow-up, language function was impaired in 88% of the children, although some improvement was noted in 57%. We conclude that the loss of previously acquired language at any age, even if that language only includes a few words or communicative gestures, is often associated with a more global regression in cognition and/or behavior and has serious implications for future function. Early identification and referral of these children is necessary to allow for diagnosis and intervention.

Abstract
The Child Neurology Society and American Academy of Neurology recently proposed to formulate Practice Parameters for the Diagnosis and Evaluation of Autism for their memberships. This endeavor was expanded to include representatives from nine professional organizations and four parent organizations, with liaisons from the National Institutes of Health. This document was written by this multidisciplinary Consensus Panel after systematic analysis of over 2,500 relevant scientific articles in the literature. The Panel concluded that appropriate diagnosis of autism requires a dual-level approach: (a) routine developmental surveillance, and (b) diagnosis and evaluation of autism. Specific detailed recommendations for each level have been established in this document, which are intended to improve the rate of early suspicion and diagnosis of, and therefore early intervention for, autism.

Abstract
As disorders on the autistic spectrum are behaviorally defined, there is no medical test to diagnose autism. The purpose of a medical evaluation is to detect particular etiologies, and manifestations like clinical or subclinical epilepsy or behavior problems that might mandate pharmacologic intervention. Defining a unique syndrome or genetic etiology may benefit other family members, although, currently, specific causes are detectable in only a small minority of individuals on the autistic spectrum. The paper lists elements of the history, examination, and laboratory testing most likely to be informative in clinical practice. Ordering large numbers of tests in the absence of a specific clinical indication is not recommended because it is invasive, wasteful and unlikely to generate useful data. This is not true, of course, in the context of a hypothesis-driven, approved research protocol where collecting standardized data and applying the most up-to-date research technologies is appropriate.

Abstract
Autism is a behaviorally defined, life-long static developmental disorder of the brain that is poised for neurobiological investigation. It affects at least 1 or 2 in 1000 persons and has a broad range of severity. It has multiple causes, with genetics playing a major role. According to the DSM-IV, defining features are impaired sociability, language and communication, and range of interests and activities. Mental deficiency is frequent but by no means universal. The cognitive profile is characteristic, occasionally with a superior but narrow talent. Perseveration, concreteness, affective blunting, and lack of insight into other persons' thinking may be conspicuous. The neurological basis of autism's many sensorimotor features, including stereotypies, is unknown. Attention and sleep are affected, and one third of individuals experience epilepsy by adulthood. Whether subclinical epilepsy plays a role in the developmental regression of the one third of the toddlers who lose their language skills and become autistic remains to be determined. Clinical neuroimaging and biochemical investigations are generally unremarkable. Fewer than 35 brains have been examined pathologically, none with modern techniques. The findings thus far suggest subtle prenatal neuronal maldevelopment in the cerebellum and certain limbic structures. Abnormalities in distributed networks involving serotonin and perhaps other neurotransmitters require further documentation.
