Autism and the Nature of Intelligence
The debate about the nature of intelligence and giftedness continues.
Led by psychologist Laurent Mottron of the University of Montreal, a team gave both autistic kids and normal kids two of the most popular IQ tests used in schools: the WISC, which relies heavily on language; and the Raven’s Progressive Matrices, which measures the ability to infer rules, to set and manage goals, and to do high-level abstractions. The Raven’s presents arrays of complicated patterns with one missing, and test takers are required to choose the one that would logically complete the series. The test demands a good memory, focused attention and other “executive skills,” but—unlike the WISC—it doesn’t require much language.
The difference between the scores of the autistic and normal children on the WISC and the Raven’s test was striking. Not a single autistic child scored in the “high intelligence” range of the WISC. In fact, a third of the children with autism had WISC scores in the mentally retarded range. Yet fully a third scored in the “high intelligence range” on the Raven’s.
The scientists ran the same experiment with autistic and normal adults, with the same result.
While it is probably true that people with autism possess extraordinary perceptual skills, and that they use unique cognitive pathways for problem solving, their intelligence clearly goes far beyond rote memory and perception to include complex reasoning ability.
I would like to know…
What implications does this research have for the education of autistic children?
