This study investigated whether individuals with ASD (autistic spectrum disorders) are able to identify driving hazards, given their difficulties processing social information, Klin et al. ("Archives of General Psychiatry" 59: 809-816, 2002). Twenty-three adult males with ASD and 21 comparison participants viewed 10 video clips containing driving…

Caregiver report on the Adaptive Behavior Assessment System-II (ABAS) for 40 high-functioning individuals with Autism Spectrum Disorders (ASD) and 30 typically developing (TD) individuals matched for age, IQ, and sex ratio revealed global adaptive behavior deficits in ASD, with social skills impairments particularly prominent. Within the ASD…

The literature suggests children with autism use communication primarily for requests and protests, and almost never for information-seeking. This study investigated whether teaching "Where" questions using intrinsic reinforcement procedures would produce the generalized use of the question, and whether concomitant improvements in related language…

Multiple dimensions of comprehensive treatment models (CTMs) for learners with autism were evaluated in this study. The purpose of the study was to provide evaluative information upon which service providers, family members, and researchers could make decisions about model adoption, selection for a family member, or future research. Thirty CTMs…

Using daily diary methods, mothers of adolescents and adults with ASD (n = 86) were contrasted with a nationally representative comparison group of mothers of similarly-aged unaffected children (n = 171) with respect to the diurnal rhythm of cortisol. Mothers of adolescents and adults with ASD were found to have significantly lower levels of…

It is widely assumed that children with autism have a diminished understanding of the perception-knowledge relationship, as a specific manifestation of a theory of mind (ToM) impairment. However, such a conclusion may not be justified on the basis of previous studies, which have suffered from significant methodological weaknesses. The current…

People with ASD have deficits in their social skills and may therefore experience lower relationship satisfaction. This study investigated possible mechanisms to explain whether and how autistic traits, measured with the AQ, influence relationship satisfaction in a non-clinical sample of 195 married couples. More autistic traits were associated…

Use of complementary and alternative medicine (CAM) treatments have been increasing for children with autistic spectrum disorder (ASD). In this study, 38 Turkish parents of children with ASD were surveyed related with their use of CAM treatments, experiences, and views for each treatment. They mentioned "Vitamins and minerals", "Special Diet",…

Restricted and repetitive behaviors in autism spectrum disorders have been conceptualized to reflect impaired executive functions. In the present study, we investigated the performance of 6-17-year-old children with and without an autism spectrum disorder on a dimension-change card sort task that explicitly indicated sorting rules on every trial.…

We employed semi-structured tests to determine whether children with autism produce and comprehend deictic (person-centred) expressions such as "this"/"tilde" "here"/"there" and "come"/"go", and whether they understand atypical non-verbal gestural deixis in the form of directed head-nods to indicate location. In Study 1, most participants…

The present paper aims to investigate whether individuals with Asperger syndrome (AS) show global humor processing deficits or whether humor comprehension and appreciation depends on stimulus characteristics. Non-verbal visual puns, semantic and Theory of Mind cartoons were rated on comprehension, funniness and the punchlines were explained. AS…

The present study examined intake data from 384 participants with autism spectrum disorders (ASD) and a comparison group of 100 participants with dyslexia on nine standardized measures of decoding and comprehension. Although diagnostic groups were based on parental reports and could not be verified independently, we were able to observe…

The psychometric characteristics of the IBR Modified Overt Aggression Scale were studied in over 2,000 people with Intellectual Disability (ID). Reliability ranged from good to excellent. Aggression toward others and objects was highest in the youngest adults, in those in the moderate to severe range of ID, and in those with an autism spectrum…

In obsessive-compulsive disorder (OCD), the relationship between autism spectrum disorders (ASD), attention-deficit/hyperactivity disorder (ADHD) symptom, and obsessive-compulsive (OC) symptom dimensions and severity has scarcely been studied. Therefore, 109 adult outpatients with primary OCD were compared to 87 healthy controls on OC, ADHD and…

Although temporal processing has received little attention in the autism literature, there are a number of reasons to suspect that people with autism spectrum disorder (ASD) may have particular difficulties judging the passage of time. The present study tested a group of 20 high-functioning adults with ASD and 20 matched comparison participants on…
