Hansen, John A. – Journal of Autism and Developmental Disorders, 2019
Assessment of individuals on the autism spectrum often includes a measure of nonverbal IQ. One such measure is the Raven's Standard Progressive Matrices (RSPM). For large research studies with participants distributed nationally it is desirable for assessments to be available online. Because time is a premium, it is ideal that the measure produces…

Terzi, Arhonto; Marinis, Theodoros; Francis, Kostantinos – Journal of Autism and Developmental Disorders, 2016
In order to study problems of individuals with Autism Spectrum Disorders (ASD) with morphosyntax, we investigated twenty high-functioning Greek-speaking children (mean age: 6;11) and twenty age- and language-matched typically developing children on environments that allow or forbid object clitics or their corresponding noun phrase. Children with…

Smith, Alastair D.; Kenny, Lorcan; Rudnicka, Anna; Briscoe, Josie; Pellicano, Elizabeth – Journal of Autism and Developmental Disorders, 2016
Drawing tasks are frequently used to test competing theories of visuospatial skills in autism. Yet, methodological differences between studies have led to inconsistent findings. To distinguish between accounts based on local bias or global deficit, we present a simple task that has previously revealed dissociable local/global impairments in…

Nader, Anne-Marie; Courchesne, Valérie; Dawson, Michelle; Soulières, Isabelle – Journal of Autism and Developmental Disorders, 2016
Wechsler Intelligence Scale for Children (WISC) is widely used to estimate autistic intelligence (Joseph in The neuropsychology of autism. Oxford University Press, Oxford, 2011; Goldstein et al. in "Assessment of autism spectrum disorders." Guilford Press, New York, 2008; Mottron in "J Autism Dev Disord" 34(1):19-27, 2004).…

Montgomery, Charlotte B.; Allison, Carrie; Lai, Meng-Chuan; Cassidy, Sarah; Langdon, Peter E.; Baron-Cohen, Simon – Journal of Autism and Developmental Disorders, 2016
The present study examined whether adults with high functioning autism (HFA) showed greater difficulties in (1) their self-reported ability to empathise with others and/or (2) their ability to read mental states in others' eyes than adults with Asperger syndrome (AS). The Empathy Quotient (EQ) and "Reading the Mind in the Eyes" Test…

Kunda, Maithilee; Goel, Ashok K. – Journal of Autism and Developmental Disorders, 2011
We analyze the hypothesis that some individuals on the autism spectrum may use visual mental representations and processes to perform certain tasks that typically developing individuals perform verbally. We present a framework for interpreting empirical evidence related to this "Thinking in Pictures" hypothesis and then provide…

Bolte, Sven; Dziobek, Isabel; Poustka, Fritz – Journal of Autism and Developmental Disorders, 2009
Owing to higher performance on the Raven's Progressive Matrices (RPM) than on the Wechsler Intelligence Scales (WIS), it has recently been argued that intelligence is underestimated in autism. This study examined RPM and WIS IQs in 48 individuals with autism, a mixed clinical (n = 28) and a neurotypical (n = 25) control group. Average RPM IQ was…

Goin-Kochel, Robin P.; Mazefsky, Carla A.; Riley, Brien P. – Journal of Autism and Developmental Disorders, 2008
Little evidence supports that siblings with autism exhibit the same behaviors; however, some findings suggest that level of functioning shows familial aggregation. We tested this notion among multiplex families participating with the Autism Genetic Resource Exchange (AGRE) Consortium, using scores on the "Peabody Picture Vocabulary Test-Third…

Mottron, Laurent – Journal of Autism and Developmental Disorders, 2004
A meta-analysis was performed on the 133 cognitive and behavioral papers in autism using comparison groups in the 1999-2002 period. High-functioning (average IQ: 84.7), adolescents (average, 14.4 years) are largely dominant. IQ is the most frequent matching variable in use (51.2%). The instruments that are most frequently used to determine IQ or…
