Transcript of What if IQ tests did not reveal the true intelligence of chi

Under the surface
Tip of the Iceberg
Examples of Standard IQ test questions:

Surprising Results
Isabelle Soulieres at Harvard University discovered that "[o]n average, autistic students performed 30 percentile points better on the Raven test than on WISC. Some kids jumped 70 percentile points" (Eveleth, 2011). Children without a diagnosis scored equitably on both tests. (Begley, 2007)These results leave us to wonder: Are the test results achieved on standard intelligence tests truly accurate reflections of these childrens' abilities?
What if IQ tests do not reveal the true intelligence of children diagnosed with Autism Spectrum Disorder?
"[T]hree quarters of autistics are classified as having below-normal intelligence, with many deemed mentally retarded" (Begley, 2007). Is this an accurate measure of their intelligence or a reflection on their communication challenges?
If children with Autism Spectrum Disorder lack the skills required to have a meaningful verbal conversation, how can anyone expect them to respond appropriately to verbal questions, especially when they are presented by a stranger, the tester? (Begley, 2007)
Standard intelligence tests, such as the Weschler Intelligence Scale for Children (WISC-IV) and the Stanford-Binet, are commonly used to test children's intelligence, but are heavily dependent on the ability of children to communicate using appropriate verbal skills. (Sicile-Kira, 2011)
According to Sicile-Kira, "[T]hese IQ tests do not tap the true cognitive ability of many children on the autistic spectrum, but rather tell us more about their communication...difficulties" (2011).

Why IQ tests are so important:
Considering that IQ tests results are used, not only to assist in the diagnosis of ASD children, but also to give direction for their education goals, it is imperative to have accurate test results (Baum, 2011, p.2).
Is there a test that could reveal
the true intelligence of these children?

In the Raven Progressive Matrices test children
"analyze three-by-three arrays of geometric designs, with one missing, and choose (from six or eight possibilities) the design that belonged in the empty place" (Begley, 2007).
A New Way to Test Intelligence
Tip of the Iceberg
Until we know for certain which type of test most accurately measures intelligence, we need to consider that the intelligence scores may, in fact, only be the tip of the iceberg. We should consider that an ASD child's intelligence may be more accurately reflected in the Raven's Test. Perhaps scores from both the standard IQ tests and the Raven's test need to be used as indicators of the intelligence of children diagnosed with Autism Spectrum Disorder.
