Gaze avoidance and perseverative language impact pragmatics in autism spectrum disorder (ASD) and fragile X syndrome (FXS). We examined these features during conversation samples in boys with ASD (n = 10) and boys with FXS and ASD (FXS+ASD; n = 10). Both groups had similar high rates of gaze avoidance and topic and conversation device perseverations, yet these features were not correlated with one another. Boys with FXS+ASD produced a higher proportion of single utterance perseverations. Results from this study highlight the need for future research to identify potential mechanisms influencing the presence of language perseverations and gaze avoidance...

Autism Spectrum Disorder (ASD) is often accompanied by deficits in speech and language processing. Speech processing relies heavily on the integration of auditory and visual information, and it has been suggested that the ability to detect correspondence between auditory and visual signals helps to lay the foundation for successful language development. The goal of the present study was to examine whether young children with ASD show reduced sensitivity to temporal asynchronies in a speech processing task when compared to typically developing controls, and to examine how this sensitivity might relate to language proficiency...

The phenotypic heterogeneity of Autism Spectrum Disorders (ASD) presents particular research challenges in the assessment of symptom severity, while the standardized Autism Diagnostic Observation Schedule (ADOS) scores present a severity metric, namely calibrated severity scores (CSS) that are relatively impervious to individual characteristics. To date, no studies have examined the convergent validity of CSS in Chinese sample populations. The present study investigated the validity of the ADOS-CSS using a sample of 321 children aged 2-18 years with ASD, and developed upon existing literature examining the influence of non-ASD-specific characteristics on other types of measures including Autism Diagnostic Interview-Revised (ADI-R), Social Responsiveness Scale (SRS), and Vineland Adaptive Behavior Scales (VABS)...

Research has demonstrated that caregivers' use of intervention strategies can support their children's social engagement and communication. However, it is not clear to what degree caregivers must master the strategies to effectively support gains in social communication, specifically, core challenges such as joint attention language (comments). Twenty-two minimally verbal school-age children with autism received a social communication intervention with caregiver coaching. Through 10 min caregiver-child play interactions at eight time points, significant increase were found in children's spontaneous language...

Autism spectrum disorders (ASD) are characterized by impairments in language and communication development, social behavior, and the occurrence of stereotypic patterns of behavior and interests. Despite substantial speculation about causes of ASD, its exact etiology remains unknown. Recent studies highlight a link between immune dysfunction and behavioral traits. Various immune anomalies, including humoral and cellular immunity along with abnormalities at the molecular level, have been reported. There is evidence of altered immune function both in cerebrospinal fluid and peripheral blood...

Father-child and mother-child interactions were examined in order to investigate concurrent associations between three characteristics of parental broad autism phenotype (i.e., aloofness, rigidity, pragmatic language deficits), parental verbal responsiveness, and language skills of children with ASD. Results for mothers indicated that aloofness and rigidity were negatively associated with both child-initiated engagement and child language skills. Maternal aloofness was also negatively correlated with verbal responsiveness to their children, but rigidity was not...

Autism spectrum disorder (ASD) is diverse, manifesting in a wide array of phenotypes. However, a consistent theme is reduced communicative and social abilities. Auditory processing deficits have been shown in individuals with ASD-these deficits may play a role in the communication difficulties ASD individuals experience. Specifically, children with ASD have delayed neural timing and poorer tracking of a changing pitch relative to their typically developing peers. Given that accurate processing of sound requires highly coordinated and consistent neural activity, we hypothesized that these auditory processing deficits stem from a failure to respond to sound in a consistent manner...

Within the neurocognitive literature there is much debate about the role of the motor system in language, social communication and conceptual processing. We suggest, here, that autism spectrum conditions (ASC) may afford an excellent test case for investigating and evaluating contemporary neurocognitive models, most notably a neurobiological theory of action perception integration where widely-distributed cell assemblies linking neurons in action and perceptual brain regions act as the building blocks of many higher cognitive functions...

The Broad autism phenotype (BAP) refers to a set of subclinical behavioural characteristics qualitatively similar to those presented in Autism spectrum disorders (ASDs). The BAP questionnaire (BAPQ) has been widely used to assess the BAP both in relatives of ASD people and within the general population. The current study presents the first Spanish version of the BAPQ (BAPQ-SP) and analyses its psychometric properties, including validity evidences based on the BAPQ scores relationship with other variables. Our results only support the use of the Aloof and Rigid sub-scales to assess this phenotype, whereas Pragmatic Language sub-scale seems to be the main source of misfit...

Deficits in communication are a core feature of autism spectrum disorder (ASD), however, structural language abilities are highly variable, ranging from minimally verbal to superior linguistic skills. Differences in the anatomy of cortical language regions, including anterior and posterior areas, have been found in ASD. It remains unclear, however, if anatomical differences distinguish individuals with impaired expressive language from those without such deficits. In addition, anatomical differences have not been explored in children with extremely low expressive language...

OBJECTIVE: A social pragmatic communication disorder is one of the primary characteristics of children with autism. Although several measures of pragmatics and social communication exist, many are not comprehensive, do not examine the quality of interactions across contexts and interlocutors, and cannot be easily administered and interpreted. The aim of this article is to report on preliminary data collected using the Greek version of comprehensive social communication and pragmatic language questionnaires completed by parents and teachers interacting with young children in different contexts...
