The authors hypothesised that red dermographism--a skin reaction involving the cholinergic system--is more frequent in children with autism spectrum disorders (ASDs) than in children exhibiting typical development. We used a dermatological examination to study red dermographism in this transverse study, which compared forty six children with ASDs…

Negative feedback was explored as a potential mechanism that may exacerbate perseverative behaviours in individuals with Asperger's syndrome (AS). The current study compared 50 individuals with AS and 50 typically developing (TD) individuals for their abilities to successfully complete the Wisconsin Card Sorting Task (WCST) in the presence or…

One-hundred nine children 3-16 years of age diagnosed with Autistic Disorder, Pervasive Developmental Disorder Not Otherwise Specified, or Asperger's Syndrome were studied. Children resided in six states in the United States. Using moderation analysis via multiple regression, verbal communication and challenging behaviors and how they interact…

We aimed to investigate the Health Related Quality of Life and related clinical variables (HRQoL) of children with Autism Spectrum Disorders (ASD). We included 102 children with ASD (46 with autism, 38 with pervasive developmental disorder not otherwise specified (PDD-NOS) and 18 with Asperger's syndrome (AS)) and 39 typically developing children…

This systematic review aims to determine whether or not structural magnetic resonance imaging (sMRI) data support the DSM-5 proposal of an autism spectrum disorder (ASD) diagnostic category, and whether or not classical DSM-IV autistic disorder (AD) and Asperger syndrome (AS) categories should be subsumed into it. The most replicated sMRI findings…

This study was designed to identify specific difficulties and associated features related to the problems with social interaction experienced by individuals with pervasive developmental disorder-not otherwise specified (PDD-NOS) using an emotion-recognition task. We compared individuals with PDD-NOS or Asperger's disorder (ASP) and typically…

This study evaluated the psychometric properties of the Chinese version of the Social Responsiveness Scale (Chinese SRS). We assessed 1419 grade 1 to grade 8 students from northern Taiwan and 401 clinic-based participants (aged 3-20, male 90.3%). All clinic-based participants were clinically diagnosed with autism spectrum disorders (ASDs),…

The purpose of this paper was to update the psychometrics of the "Matson Evaluation of Social Skills for Youngsters" ("MESSY") with children with Autism Spectrum Disorders (ASD), specifically with respect to internal consistency, split-half reliability, and inter-rater reliability. In Study 1, 114 children with ASD (Autistic Disorder, Asperger's…

This study addressed what role movement timing irregularities have in producing the motor deficits documented in Asperger's Syndrome (AS). Participants included males with AS (n = 14) and without (n = 16), matched by age (7-23 years) and with no significant IQ differences. They completed measures of timing perception (comparisons of tempo of…

People with Asperger's syndrome (AS) experience mental comorbidities, and behavioral symptoms that can deepen social isolation and handicaps. We compared the frequency of mental and behavioral symptoms, motor abnormality, and life history between adults with AS and those with no mental disorders but with disturbance of social functions and…

The aim of this study was to investigate whether children with high-functioning autism (HFA) and Asperger's syndrome (AS) can be differentiated from each other and from typically developing children on their cognitive profiles. The present study included a total of 45 participants: children with autism (high-functioning autism or Asperger's…

There is a paucity of evidence concerning the patterns of multi-informant agreement in populations with Autism Spectrum Disorders (ASD). This study compared ratings of behaviour and emotional problems and social functioning provided by 45 adolescents aged 12-18 years, with Autistic or Asperger's Disorder with ratings by their parents and teachers.…

This study aimed to (a) assess language comprehension in children with autism spectrum disorders (ASD) without intellectual disability, (b) assess differences between ASD diagnostic subgroups, and (c) analyze the relationship between language comprehension and performance and verbal IQ, respectively. The 94 participants (83 boys, 11 girls; 4:0-6:8…

ASD subjects are described as showing particular difficulty in decoding emotional patterns. This paper explored linguistic and conceptual skills in response to emotional stimuli presented as emotional faces, scripts (pictures) and interactive situations (videos). Participants with autism, Asperger syndrome and control participants were shown…

Deficits in executive functioning (EF) have been proposed to underlie the behavioural patterns of individuals with an autism spectrum disorder. Researchers have shown that the Asperger's syndrome (AS) population performs more poorly than typically developing controls on many EF tasks. However, the research literature is inconsistent in identifying…
