Direct linkBooth, Adam J.; Rodgers, Jonathan D.; Volker, Martin A.; Lopata, Christopher; Thomeer, Marcus L. – Journal of Autism and Developmental Disorders, 2019
This study examined psychometric characteristics of the Diagnostic Analysis of Nonverbal Accuracy--Second Edition (DANVA-2) in 121 children, ages 6 to 13 years, with high-functioning autism spectrum disorder (HFASD). Internal consistency for adult and child faces subtests were 0.70 and 0.75, respectively. Immediate test-retest reliability in the…

Kenworthy, Lauren; Wallace, Gregory L.; Powell, Kelly; Anselmo, Cheryl; Martin, Alex; Black, David O. – Research in Autism Spectrum Disorders, 2012
Language ability is a known predictor of outcome in children with autism but plays a more controversial role for higher functioning children with autism spectrum disorders (ASD). We studied the relationship between early language milestones and later structural language, adaptive functioning and autism symptoms in a sample of 76 children (mean age…

Chen, Fei; Planche, Pascale; Lemonnier, Eric – Research in Autism Spectrum Disorders, 2010
Some early studies showed discordance in cognitive strengths and weaknesses in individuals with high-functioning autism (HFA) or Asperger's syndrome (AS). The present study administered the French version of Colored Raven's Progressive Matrices in 14 children with HFA/AS and in 26 chronological age matched peers with typical development. We found…

Estigarribia, Bruno; Martin, Gary E.; Roberts, Joanne E.; Spencer, Amy; Gucwa, Agnieszka; Sideris, John – Applied Psycholinguistics, 2011
We examined recalled narratives of boys with fragile X syndrome with autism spectrum disorder (FXS-ASD; N = 28) and without ASD (FXS-O; N = 29), and compared them to those of boys with Down syndrome (N = 33) and typically developing (TD) boys (N = 39). Narratives were scored for mentions of macrostructural story grammar elements (introduction,…

Gaffrey, Michael S.; Kleinhans, Natalia M.; Haist, Frank; Akshoomoff, Natacha; Campbell, Ashley; Courchesne, Eric; Muller, Ralph-Axel – Neuropsychologia, 2007
Language delay and impairment are salient features of autism. More specifically, there is evidence of atypical semantic organization in autism, but the functional brain correlates are not well understood. The current study used functional MRI to examine activation associated with semantic category decision. Ten high-functioning men with autism…
