The Level and Nature of Autistic Intelligence II: What about Asperger Syndrome?
TLDR
Investigation of findings of autistic strengths in performance on Raven's Progressive Matrices investigated whether these findings extend to Asperger syndrome, an autistic spectrum subgroup characterized by verbal peaks of ability, and whether the cognitive mechanisms underlying autistic and Aspergers RPM performance differ.
Inter-individual cognitive variability in children with Asperger's syndrome
TLDR
It is proposed that children with Asperger's syndrome are characterized by a distinct, uneven pattern of cognitive strengths and weaknesses.
Assessing intelligence at autism diagnosis: mission impossible? Testability and cognitive profile of autistic preschoolers
TLDR
Testability increased with age in both groups, was generally lower in AS children, but not related to their test performance, and flexible testing is introduced to introduce the usefulness of flexible testing.
Behavioral, Cognitive and Neural Markers of Asperger Syndrome
TLDR
Behavior, motor skills and language capabilities of individuals with Asperger are compared to those in healthy controls and common findings across MRI and fMRI based studies associated with behavior and cognitive disabilities are highlighted.
Visual/verbal-analytic reasoning bias as a function of self-reported autistic-like traits
TLDR
This research investigated whether self-reported autistic-like traits in a university student sample, assessed using the Autism-Spectrum Quotient (AQ), predict performance on Raven’s Advanced Progressive Matrices, and found that reporting poorer social skills but better attention switching predicted a higher Advanced matrices score overall.
Neuropsychological Differences Among Children With Asperger Syndrome, Nonverbal Learning Disabilities, Attention Deficit Disorder, and Controls
TLDR
The NLD group showed particular difficulty on visual-spatial, visual-motor, and fluid reasoning measures compared to the other groups, and there was also a significant verbal-performance IQ split in this group related to difficulty in social functioning.
Functional Alterations in Neural Substrates of Geometric Reasoning in Adults with High-Functioning Autism
TLDR
Results indicate altered pattern of functional specialization and integration in the neural system for geometric reasoning in ASC, which may explain its atypical cognitive pattern, including performance on the Raven's Matrices test.
Brief Report: The Level and Nature of Autistic Intelligence Revisited
TLDR
Average RPM IQ was higher than WISIQ only in the autism group, albeit to a much lesser degree than previously reported and only for individuals with WIS IQs <85, and the WIS are recommended as first choice IQ measure in high functioning individuals.
The effects of context processing on social cognition impairments in adults with Asperger's syndrome
TLDR
The results suggest that social cognition deficits in AS imply a reduced ability to implicitly encode and integrate contextual cues needed to access social meaning, which has implications for the diagnosis and treatment of AS and other neuropsychiatric conditions.

TLDR
The Wechsler Intelligence Scale for Children-Revised (WISC-R) was applied in 120 children with Asperger syndrome, autistic disorder, and attention disorders and it was suggested that Kaufman's Verbal Comprehension, Perceptual Organisation and Freedom from Distractibility factors rather than verbal IQ and performance IQ account for the variance on the WISC.

TLDR
Studies are needed that define the developmental course of the disorder and the nature of the strengths and weaknesses in both social and non-social domains, and questions about the prevalence of Asperger syndrome, about associated and secondary features, and about optimal education and management, urgently call for such studies.
The Level and Nature of Autistic Intelligence
TLDR
Assessment of autistic children on the preeminent test of fluid intelligence, Raven's Progressive Matrices, concludes that intelligence has been underestimated in autistics.

TLDR
Results show that the patients of Asperger described in the study represent a subgroup of children with very high intellectual functioning, specific circumscribed interests and talents but impaired social, communication and motor skills.
When Asperger's Syndrome and a Nonverbal Learning Disability Look Alike*
TLDR
Joey’s difficulty integrating social, visual, and emotional information caused him to be easily overwhelmed in social situations and resulted in withdrawal, and he was uncomfortable with ADHD as the primary diagnosis.
Validity and neuropsychological characterization of Asperger syndrome: convergence with nonverbal learning disabilities syndrome.
TLDR
The profile obtained for individuals with AS coincided closely with a cluster of neuropsychological assets and deficits captured by the term nonverbal learning disabilities, suggesting an empirical distinction from HFA.

TLDR
Describing and naming the syndrome has had mainly positive effects and it has highlighted the special contribution people with Asperger syndrome have made to the world.
Executive functions and developmental psychopathology.
TLDR
It is revealed that EF deficits are consistently found in both ADHD and autism but not in CD (without ADHD) or in TS, and both the severity and profile of EF deficits appears to differ across ADHD and Autism.

TLDR
This study reveals that identification of objects from a verbal label—the BPVS–PPVT–EVIP task—is a peak of ability in high functioning individuals with PDDs, and has a detrimental effect on matching based on this instrument, prompting a recommendation to replace BPVS/PPVT/EVIP or RPM by Wechsler scale as a basis of IQ/level matching.
