Despite repeated findings of abnormal corpus callosum structure in autism, the developmental trajectories of corpus callosum growth in the disorder have not yet been reported. In this study, we examined corpus callosum size from a developmental perspective across a 30-year age range in a large cross-sectional sample of individuals with autism…

Aggression is a clinically significant problem for many children and adolescents with autism spectrum disorders (ASD). However, there have been few large-scale studies addressing this issue. The current study examined the prevalence and correlates of physical aggression in a sample of 1584 children and adolescents with ASD enrolled in the Autism…

Unusual fears have long been recognized as common in autism, but little research exists. In our sample of 1033 children with autism, unusual fears were reported by parents of 421 (41%) of the children, representing 92 different fears. Many additional children had common childhood fears (e.g., dogs, bugs, and the dark). More than half of children…

We examined the effects of constructed-response matching-to-sample (CRMTS) training on the generalization of reading and spelling skills in three Japanese children with autism using a series of overlapping-syllable word sets. We taught them to construct printed words to match printed words, spoken words, and pictures through the CRMTS procedure.…

The range of interventions available for children with autism spectrum disorders (ASD) has increased in recent years. This has led to an interest in the decision-making process related to intervention choices for parents of children with ASD. The present paper reviewed 16 studies examining the factors declared by parents as affecting their…

Previous research has demonstrated that children with autism often have difficulty using and understanding non-literal language ("e.g.," irony, sarcasm, deception, humor, and metaphors). Irony and sarcasm may be especially difficult for children with autism because the meaning of an utterance is the opposite of what is stated. The current study…

Beginning with Kanner's (1943) seminal article on autism, through the current DSM-IV-R criteria for the disorder, children have been described as having difficulty with seeing overall gestalts, due to excess attention to the constituent part. In current terms, children with autism have been found to process objects at the local level differently,…

Motor stereotypies are defined as patterned, repetitive, purposeless movements. These stigmatizing motor behaviors represent one manifestation of the third core criterion for an Autistic Disorder (AD) diagnosis, and are becoming viewed as potential early markers of autism. Moreover, motor stereotypies might be a tangible expression of the…

This study examined individual differences in self-regulation, emotional and behavioral school engagement, and prosocial peer engagement in a sample of 40 children that included children with high functioning autism (HFA; n = 20) and their typical peers (n = 20). Children were 54.57 months on average at recruitment. Measures of self-regulation…

Agreement between the DSM-5, DSM-IV, and Checklist for Autism Spectrum Disorder was assessed in 125 children with autism spectrum disorder (ASD), which included high and low functioning autism (HFA and LFA) and pervasive developmental disorder not otherwise specified (PDDNOS), and children with other clinical disorders (e.g., ADHD, mental…

Postural control is a fundamental building block of each child's daily activities. The aim of this study was to compare patterns of postural sway in children with autism spectrum disorder (ASD) with typically developing children (TD). We recruited 21 schoolchildren diagnosed with ASD aged 9-14 and 30 TD pupils aged 8-15. Postural sway parameters…

Multiple electroencephalography (EEG) abnormalities have been associated with autism. In the course of clinical work, we have observed a posterior dominant EEG rhythm at higher frequency in children with autism. To test this observation, 56 EEG tracings of children with autism were compared to the EEGs of age-matched controls. Children with autism…

Children with autism spectrum disorders (ASD) have strong preferences for screen-based media, particularly video games. Although problematic video game use has been associated with behavior problems among typically developing children, the relationship between these variables has not been previously examined among children with ASD. The current…

The current study aims to describe the cognitive profile, autism profile, medical and behavioral presentation of children with a dual diagnosis of cerebral palsy (CP) and autism spectrum disorder (ASD). Little is known about the dual presentation of CP and ASD. Timely diagnosis is imperative as early intervention may impact a child's developmental…

Previous research has shown that children with autism often have deficits in deception, both in the ability to lie to others and in the ability to detect when they are being lied to. Additionally, children with autism are frequently the victims of bullying and difficulty with understanding deception likely makes the population more vulnerable to…
