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…

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…

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…

Estimates suggest that atypical eating is pervasive among children with autism spectrum disorders (ASD); however, much remains unknown regarding the nature and prevalence of feeding problems in this population due to methodological limitations, including lack of adequate assessment methods and empirical evaluation of existing measures. In the…

Autism Spectrum Disorders (ASD) are behaviorally defined neurodevelopmental disorders. The best known yet less understood characteristic of autism is its unexplained male preponderance. Using a biosocial perspective, the goal of this article is to draw attention to the role of gender-based socialization practices and behavioral expectations during…

We compared two functional behavioral assessment methods: the Questions About Behavioral Function (QABF; a standardized test) and experimental functional analysis (EFA) to identify behavioral functions of aggressive/destructive behavior, self-injurious behavior and stereotypy in 32 people diagnosed with autism. Both assessments found that self…

Studies have shown that children with ASD have increased severity and incidence of pain symptoms compared to typically developing children and children with other disorders. Pain has also been shown to act as a setting event for problem behavior. Further, problem behavior is one of the biggest impediments to quality of life for families and highly…

Autism spectrum disorders (ASD) are characterized by the presence of repetitive behavior and stereotyped patterns of interest and activities. It is common for clinicians to assume that repetitive behaviors are maintained by automatic reinforcement but, as with any challenging behavior, the function of stereotypy should not be assumed based on its…

L-Carnitine was proposed as a potential treatment for patients diagnosed with autism to ameliorate the behavioral symptoms associated with the disease. Thirty children diagnosed with autism were randomly assigned to receive (100 mg/kg bodyweight/day) of liquid L-carnitine (n = 16) or placebo (n = 14) for 6 months. Measurements included changes in…

Challenging behaviors are extremely prevalent within the autism spectrum disorder (ASD) population. To date, numerous factors affecting the rates of challenging behaviors within the ASD population have been examined including age, gender, ethnicity, and intellectual functioning. Controversy has arisen in regard to the effect of gender on…

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…

The purpose of this study was to examine the relation between parental emotion coaching and externalizing behaviors in children with autism spectrum disorders (ASD). Children with ASD often exhibit externalizing behaviors, particularly emotionally driven externalizing behaviors, at a higher rate than their typically developing peers. An…

The present study examined the effectiveness of Social Stories[TM], and Social Stories paired with a differential reinforcement procedure on disruptive behaviors of two elementary school children diagnosed with pervasive developmental disorder-not otherwise specified (PDD-NOS) and attention deficit hyperactivity disorder (ADHD). We implemented a…

A multiple mediation model was proposed to integrate core concepts of challenging behaviors with autistic traits to increase understanding of their relationship to quality of life (QoL). It was hypothesized that QoL is a possible mediator between the severity of challenging behaviors and autistic traits in adults with intellectual disability.…

The use of applied behavior analysis (ABA) to treat persons with autism goes back several decades. Many specific target behaviors and intervention strategies have been developed. In the last two decades the most heavily studied of these methods has been Early Intensive Behavioral Interventions (EIBI). This package of ABA methods is unique in two…
