IQ scores fail to predict academic performance in children with autism

18.11.2010
New data show that many children with autism spectrum disorders have greater academic abilities than previously thought. In a study by researchers at the University of Washington, 90 percent of high-functioning children with autism spectrum disorders showed a discrepancy between their IQ score and their performance on reading, spelling and math tests.

"Academic achievement is a potential source of self-worth and source of feeling of mastery that people may not have realized is available to children with autism," said Annette Estes, research assistant professor at the UW's Autism Center.

Improved autism diagnosis and early behavioral interventions have led to more and more children being ranked in the high-functioning range, with average to above average IQs. Up to 70 percent of autistic children are considered high-functioning, though they have significant social communication challenges.

With early interventions that improve social skills and curb problem behaviors, more high-functioning children with autism are able to learn in regular education classrooms. In Estes' study, most of the participants – 22 of 30 – were in regular education classrooms. The study was published online Nov. 2 in the Journal of Autism and Developmental Disorders.

Little is known about how these children actually perform in regular classrooms, which has implications for how to assign support services. Since IQ scores in the general population reliably predict academic performance – as measured by standardized tests for word reading, spelling and basic number skills – Estes and her colleagues thought the same would be true in their sample of 30 high-functioning 9 year olds with autism spectrum disorders.

"What we found was astounding: 27 out of the 30 children – that's 90 percent – had discrepancies between their IQ score and scores on at least one of the academic achievement tests," Estes said. "Some scored higher and some scored lower than what their IQ score would predict."

To the researchers' surprise, 18 of the 30 children tested higher than predicted on at least one of the academic tests. This was especially true for spelling and word reading. Across the three academic tests, 18 of the 30 children scored lower than what their IQs would predict, suggesting a learning disability.

Estes and her co-authors also found a link between social skills and academic ability in school. Specifically, children who had higher social skills at age 6, including introducing themselves to others and a willingness to compromise and cooperate, had better word reading skills at age 9. The children have participated in this study since they were 3 or 4 years old, when they were diagnosed with autism spectrum disorders by the staff at the UW's Autism Center.

The study did not look at the students' performance in school, a next step for the researchers. "We need to know if children with autism spectrum disorders who have these higher-than-expected scores are able to demonstrate their abilities in the classroom in terms of grades and other measures of success," Estes said. "This could influence placement in classes that adequately challenge them."

The children who scored below their predicted level may be struggling in certain subjects. "We want to get them the assistance they need to reach their potentials," Estes said.

Co-authors on the study are Geraldine Dawson, former director of the Autism Center and now the chief science officer at Autism Speaks; Vanessa Rivera, former research staff coordinator at the Autism Center and current graduate student at Central Washington University; Matthew Bryan, a UW biostatistics graduate student; and Philip Cali, a graduate research assistant at the Autism Center. The National Institute of Child Health and Human Development and the National Institute of Mental Health funded the study.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
