Children with autistic spectrum disorder and controls performed tasks of coherent motion and form detection, and motor control. Additionally, the ratio of the 2nd and 4th digits of these children, which is thought to be an indicator of foetal testosterone, was measured. Children in the experimental group were impaired at tasks of motor control,…

Mottron, L.; Lemmens, K.; Gagnon, L.; Seron, X. – Journal of Autism and Developmental Disorders, 2006
The possible use of a calendar algorithm was assessed in DBC, an autistic "savant" of normal measured intelligence. Testing of all the dates in a year revealed a random distribution of errors. Re-testing DBC on the same dates one year later shows that his errors were not stable across time. Finally, DBC was able to answer "reversed" questions that…

Holzer, Laurent; Mihailescu, Raluca; Rodrigues-Degaeff, Catherine; Junier, Laurent; Muller-Nix, Carole; Halfon, Oliver; Ansermet, Francois – Journal of Autism and Developmental Disorders, 2006
Objectives: Within a strong interdisciplinary framework, improvement in the quality of care for children with autistic spectrum disorders through a 2 year implementation program of Practice Parameters, aimed principally at improving early detection and intervention. Method: We developed Practice Parameters (PPs) for Pervasive Developmental…

Wakabayashi, Akio; Baron-Cohen, Simon; Wheelwright, Sally; Tojo, Yoshikuni – Journal of Autism and Developmental Disorders, 2006
The AQ (Autism-Spectrum Quotient) is a self-administered instrument for measuring the degree to which an adult with normal intelligence has the traits associated with the autistic spectrum. The AQ was administered in Japan to test whether the UK results would generalize to a very different culture. Three groups of subjects, adults with AS or HFA…

Gadow, Kenneth D.; DeVincent, Carla J.; Pomeroy, John – Journal of Autism and Developmental Disorders, 2006
Objective: Compares DSM-IV ADHD subtypes in large samples of 3-to-5 and 6-to-12 year old children with pervasive developmental disorder (PDD) vs. nonPDD clinic referrals. Method: Parents and teachers completed a DSM-IV-referenced rating scale. Results: ADHD subtypes were clearly differentiated from the nonADHD group and showed a differential…

Anne; Goldberg, Wendy A.; Tager-Flusbert, Helen; Volkmar, Fred R.; Lord, Catherine – Journal of Autism and Developmental Disorders, 2006
A multi-site study of 351 children with Autism Spectrum Disorders (ASD) and 31 typically developing children used caregiver interviews to describe the children's early acquisition and loss of social-communication milestones. For the majority of children with ASD who had experienced a regression, pre-loss development was clearly atypical. Children…

Anne; Tager-Flusberg, Helen; Volkmar, Fred R.; Lord, Catherine – Journal of Autism and Developmental Disorders, 2006
A multicenter study of 308 children with Autism Spectrum Disorder (ASD) was conducted through the Collaborative Programs of Excellence in Autism (CPEA), sponsored by the National Institute of Child Health and Human Development, to compare the family history of autoimmune disorders in children with ASD with and without a history of regression. A…

Hartman, Catharina A.; Luteijn, Ellen; Serra, Marike; Minderaa, Ruud – Journal of Autism and Developmental Disorders, 2006
The objective of this study was to refine the Children's Social Behavior Questionnaire (CSBQ), to reduce its length, and to verify its psychometric properties. The CSBQ is a questionnaire for parents or caregivers of children with PDD. The items describe a broad range of features that are typical of PDD, particularly in its milder forms. Based on…

Baron-Cohen, Simon; Hoekstra, Rosa A.; Knickmeyer, Rebecca; Wheelwright, Sally – Journal of Autism and Developmental Disorders, 2006
The Autism Spectrum Quotient (AQ) quantifies autistic traits in adults. This paper adapted the AQ for children (age 9.8-15.4 years). Three groups of participants were assessed: Group 1: n=52 adolescents with Asperger Syndrome (AS) or high-functioning autism (HFA); Group 2: n=79 adolescents with classic autism; and Group 3, n=50 controls. The…

Verte, Sylvie; Geurts, Hilde M.; Roeyers, Herbert; Oosterlaan, Jaap; Sergeant, Joseph A. – Journal of Autism and Developmental Disorders, 2006
The aim of this study was to investigate whether children with high-functioning autism (HFA), Asperger's syndrome (AS), and pervasive developmental disorder not otherwise specified (PDDNOS) can be differentiated from each other and from normal controls on their neurocognitive executive functioning (EF) profile. Children with HFA and AS showed the…

Age- and IQ-balanced 27 children with high-functioning (IQ greater than or equal to 70) pervasive developmental disorder not otherwise specified (HPDDNOS) and 27 children with attention-deficit/hyperactivity disorder (ADHD) were compared on the Japanese version of Wechsler Intelligence Scale for Children Third Edition (WISC-III) and the Childhood…

Sasson, Noah J. – Journal of Autism and Developmental Disorders, 2006
Both behavioral and neuroimaging evidence indicate that individuals with autism demonstrate marked abnormalities in the processing of faces. These abnormalities are often explained as either the result of an innate impairment to specialized neural systems or as a secondary consequence of reduced levels of social interest. A review of the…

To provide insight into what aspects of the emotional circuit might be affected in high-functioning autism, we measured indices of physiological emotions and of the expression of conscious feelings in 10 children with high-functioning autism or Asperger syndrome and 10 comparison participants. Pleasant, unpleasant, and neutral pictures were…

Hellings, Jessica A.; Zarcone, Jennifer R.; Reese, R. Matthew; Valdovinos, Maria G.; Marquis, Janet G.; Fleming, Kandace K.; Schroeder, Stephen R. – Journal of Autism and Developmental Disorders, 2006
Risperidone has shown safety and efficacy for aggressive and destructive behaviors in short-term studies. This longer-duration study includes a broad sample. Forty subjects, aged 8-56 years (mean=22), all with mental retardation and 36 with autism spectrum disorders participated in this 22-week crossover study, with 24 weeks of open maintenance…

Elder, Jennifer Harrison; Shankar, Meena; Shuster, Jonathan; Theriaque, Douglas; Burns, Sylvia; Sherrill, Lindsay – Journal of Autism and Developmental Disorders, 2006
This study tested the efficacy of a gluten-free and casein-free (GFCF) diet in treating autism using a randomized, double blind repeated measures crossover design. The sample included 15 children aged 2-16 years with autism spectrum disorder. Data on autistic symptoms and urinary peptide levels were collected in the subjects' homes over the 12…
