IQ Testing Underestimates Autism Spectrum Intelligence | Psych Central News.

A new study finds that traditional intelligence testing may be underestimating the capabilities of individuals displaying an autism spectrum disorder.

Researchers discovered Asperger’s individuals’ scores are much higher when they are evaluated by a test called Raven’s Progressive Matrices, which encompasses reasoning, novel problem-solving abilities, and high-level abstraction.

By comparison, scores for non-Asperger’s individuals are much more consistent across different tests. Interestingly, Asperger participants’ performance on Raven’s Matrices was associated with their strongest peaks of performance on the traditional Wechsler.

A previous study by the same group found very similar results for autistic individuals as well, whose peaks of ability are perceptual, rather than verbal as in Asperger individuals.

This observation suggests that individuals with autism spectrum disorders have a common information processing mechanism for different aspects of information (verbal vs. perceptual).
