The contributions of cognitive style and organization to processing and recalling a complex novel stimulus were examined by comparing the Rey Osterrieth Complex Figure (ROCF) test performance of children, adolescents, and adults with ASD to clinical controls (CC) and non-impaired controls (NC) using the "Developmental Scoring System."…

Koenig, Kathleen; De Los Reyes, Andres; Cicchetti, Domenic; Scahill, Lawrence; Klin, Ami – Journal of Autism and Developmental Disorders, 2009
A consistent result in the evaluation of group-delivered intervention to promote social reciprocity in children with PDDs is that outcome data are inconclusive. Lack of robust evidence of efficacy confounds understanding of these interventions and their value to the field. It is conceivable that the construct of impaired social reciprocity in PDD…

Kleinman, Jamie M.; Robins, Diana L.; Ventola, Pamela E.; Pandey, Juhi; Boorstein, Hilary C.; Esser, Emma L.; Wilson, Leandra B.; Rosenthal, Michael A.; Sutera, Saasha; Verbalis, Alyssa D.; Barton, Marianne; Hodgson, Sarah; Green, James; Dumont-Mathieu, Thyde; Volkmar, Fred; Chawarska, Katarzyna; Klin, Ami; Fein, Deborah – Journal of Autism and Developmental Disorders, 2008
Autism spectrum disorders (ASD) often go undetected in toddlers. The Modified Checklist for Autism in Toddlers (M-CHAT) was used to screen 3,793 children aged 16-30 months from low- and high-risk sources; screen positive cases were diagnostically evaluated. Re-screening was performed on 1,416 children aged 42-54 months. Time1 Positive Predictive…

Klin, Ami; Saulnier, Celine A.; Sparrow, Sara S.; Cicchetti, Domenic V.; Volkmar, Fred R.; Lord, Catherine – Journal of Autism and Developmental Disorders, 2007
The relationship between adaptive functioning ("ability") and autism symptomatology ("disability") remains unclear, especially for higher functioning individuals with autism spectrum disorder (ASD). This study investigates "ability" and "disability" using the "Vineland" and "Autism Diagnostic Observation Schedule" (ADOS), respectively, in two…

Paul, Rhea; Miles, Stephanie; Cicchetti, Domenic; Sparrow, Sara; Klin, Ami; Volkmar, Fred; Coflin, Megan; Booker, Shelley – Journal of Autism and Developmental Disorders, 2004
The purpose of this study is to provide a microanalysis of differences in adaptive functioning seen between well-matched groups of school-aged children with autism and those diagnosed as having Pervasive Developmental Disorder-Not Otherwise Specified, all of whom functioned in the mild to moderate range of intellectual impairment. Findings…

Tsatsanis, Katherine D.; Dartnall, Nancy; Cicchetti, Domenic; Sparrow, Sara S.; Klin, Ami; Volkmar, Fred R. – Journal of Autism and Developmental Disorders, 2003
The concurrent validity of the original and revised versions of the Leiter International Performance Scale was examined with 26 children (ages 4-16) with autism. Although the correlation between the two tests was high (.87), there were significant intra-individual discrepancies present in 10 cases, two of which were both large and clinically…

This study of hyperlexia in 80 children with developmental delays found no significant differences in the frequency of hyperlexia in girls compared with boys; a significantly elevated frequency of hyperlexia in children diagnosed with pervasive developmental disorders (PDD) compared with children with non-PDD diagnoses; and a similar range of IQ…

Buitelaar, Jan K.; Van der Gaag, Rutger; Klin, Ami; Volkmar, Fred – Journal of Autism and Developmental Disorders, 1999
A study compared characteristics of individuals with mild retardation and clinically classified as autistic disorder (n=205), Pervasive Developmental Disorder Not Otherwise Specified (PDDNOS) (n=80), and other non-PDD disorders (n=174). Only a few items from the ICD-10 and DSM-IV discriminated the PDDNOS group from other disorders. Suggested…
