Alderson-Day, Ben; McGonigle-Chalmers, Margaret – Journal of Autism and Developmental Disorders, 2011
Fourteen children with autism spectrum disorders (ASD) and fourteen age-matched typically-developing (TD) controls were tested on an adapted version of the Twenty Questions Task (Mosher and Hornsby in Studies in cognitive growth. Wiley, New York, pp 86-102, "1966") to examine effects of content, executive and verbal IQ factors on category use in…

Falter, Christine M.; Plaisted, Kate C.; Davis, Greg – Journal of Autism and Developmental Disorders, 2008
It has been hypothesised that autism is an extreme version of the male brain, caused by high levels of prenatal testosterone (Baron-Cohen 1999). To test this proposal, associations were assessed between three visuo-spatial tasks and prenatal testosterone, indexed in second-to-fourth digit length ratios (2D:4D). The study included children with…

Sheppard, Elizabeth; Ropar, Danielle; Mitchell, Peter – Journal of Autism and Developmental Disorders, 2007
Weak Central Coherence (Frith, 1989) predicts that, in autism, perceptual processing is relatively unaffected by conceptual analysis. Enhanced Perceptual Functioning (Mottron & Burack, 2001) predicts that the perceptual processing of those with autism is less influenced by conceptual analysis only when higher-level processing is detrimental to…

Peterson, Candida C. – Journal of Autism and Developmental Disorders, 2005
This study examined theory of mind (ToM) and concepts of human biology (eyes, heart, brain, lungs and mind) in a sample of 67 children, including 25 high functioning children with autism (age 6-13), plus age-matched and preschool comparison groups. Contrary to Baron-Cohen [1989, "Journal of Autism and Developmental Disorders," 19(4),…

Gepner, Bruno; Mestre, Daniel R. – Journal of Autism and Developmental Disorders, 2002
Comparison of children (n=6) with either autism or Asperger syndrome (AS) and children (n=9) with neither condition found overall postural instability was significantly reduced in autistic children compared with both AS and normal children and confirms the existence of a visuo-postural detuning in autistic children. Results suggest a…

Hauck, Joy A.; Dewey, Deborah – Journal of Autism and Developmental Disorders, 2001
This study compared hand preference and motor skills in 20 children with autism with 40 children either typically developing or with developmental delays. Results indicated that the lack of hand preference in children with autism was not a function of their cognitive delay or a lack of motor skills. Results supported the bilateral brain…

Brook, Sarah Lister; Bowler, Dermot M. – Journal of Autism and Developmental Disorders, 1992
A review of the literature on children with language disorders characterized by semantic and pragmatic impairments suggests that some of these conditions may stem from the same fundamental cognitive and interpersonal difficulties found in early childhood autism. A summary of recent research and theory in autism is also presented. (Author/DB)

Baron-Cohen, Simon – Journal of Autism and Developmental Disorders, 1988
This paper reviews the literature describing the pervasive deficits in social relations and pragmatics found in autistic children. It then considers two different psychological theories of these phenomena, the Affective theory and the Cognitive theory, concludes that the Cognitive theory better predicts behavior patterns, and suggests future…

Ohta, Masataka – Journal of Autism and Developmental Disorders, 1987
Analysis of the conceptions of spatial relations, size comparisons, and gesture imitations of 16 autistic children (ages 6-14 years) with IQs over 70 indicated an inability to acquire concepts of size comparison and spatial relationships through verbal instructions, suggesting a cognitive deficit of impaired symbolic-representational functioning.…
