This study examined differences in the ability to decode emotion through facial expression, prosody, and verbal content between 14 children with Asperger's Syndrome (AS) and 16 typically developing peers. The ability to decode emotion was measured by the Perception of Emotion Test (POET), which portrayed the emotions of happy, angry, sad, and…

Autism symptoms, including impairments in language development, social interactions, and motor skills, have been difficult to model in rodents. Since children exposed in utero to sodium valproate (VPA) demonstrate behavioral and neuroanatomical abnormalities similar to those seen in autism, the neurodevelopmental effects of this antiepileptic…

One aspect of autistic language that has been infrequently researched is vocabulary and the conceptual knowledge underpinning individual words or word types. In this descriptive study we investigate anomalous vocabulary use in a 70,000-word corpus of conversational autistic language and examine evidence that concept formation, and hence…

This study examined whether language deficits persist even in children with optimal outcomes. We examined a group of children with prior diagnoses on the autism spectrum who had IQs in the normal range, were in age-appropriate mainstream classes, and had improved to such an extent that they were considered to be functioning at the level of their…

Autistic spectrum disorders (ASD) can be difficult to diagnose in toddlers. This study compared diagnostic measures (ADOS-G, ADI-R, CARS, and clinical judgment using DSM-IV criteria) applied to toddlers. Results indicated that the ADOS-G, CARS, and clinical judgment agreed with each other but not with the ADI-R. Many of the children classified…

The Kiddie Schedule for Affective Disorders and Schizophrenia was modified for use in children and adolescents with autism by developing additional screening questions and coding options that reflect the presentation of psychiatric disorders in autism spectrum disorders. The modified instrument, the Autism Comorbidity Interview-Present and…

Autism is a neurodevelopmental disorder with a specific pattern of behavioural, communication and social problems. Additional mental health problems are often poorly understood and undetected. This study investigates the level and pattern of emotional and behavioural problems in young people with autism compared with children with intellectual…

Little is known about the use of medical services by children who have autism (ASD). Provide nationally representative data for health service utilization and expenditures of children with ASD. Cross-sectional survey using the Medical Expenditure Panel (MEPS), and National (Hospital) Ambulatory Medical Care Surveys (N(H)AMCS). A total of 80…

Autism involves a basic impairment in social cognition. This study investigated early stage face processing in young children with autism by examining the face-sensitive early negative event-related brain potential component in 3-4 year old children with autism spectrum disorder (ASD), typical development, and developmental delay. Results…

Objective of the study was to replicate in adults our previous findings of decreased heart rate and normal endocrine responses to stress in autistic children and to elucidate the discrepancy between autonomic and endocrine stress responses by including epinephrine, norepinephrine, oxytocin and vasopressin measurements. Ten autistic spectrum…

Previous studies suggest that complementary and alternative medical (CAM) therapy use in children with chronic illnesses is higher than in children in the general population. In this study, we investigated patterns of CAM therapy use in children diagnosed with autism spectrum disorders (ASD, n = 50) as compared to a control population of children…

This study investigated reading skills in 41 children with autism spectrum disorder. Four components of reading skill were assessed: word recognition, nonword decoding, text reading accuracy and text comprehension. Overall, levels of word and nonword reading and text reading accuracy fell within average range although reading comprehension was…

Parents of children with autism frequently turn to the service delivery system to access supports designed to help adapt to the challenges of having a child with a life-long impairment. Although studies have suggested various supports and coping strategies that are effective for adapting, few studies have examined parents' own perceptions of…

Social escape behavior is a common behavioral feature of individuals with fragile X syndrome (fraX). In this observational study, we examined the effect of antecedent social and performance demands on problem behaviors in four conditions: face-to-face interview, silent reading, oral reading and a singing task. Results showed that problem behaviors…

Baron-Cohen's [(2002) "Trends in Cognitive Sciences," 6, 248-255] "extreme male brain" theory of autism is investigated by examining the relationships between theory of mind, central coherence, empathising, systemising and autistic-like symptomatology in typical undergraduates. There were sex differences in the expected directions on all tasks.…
