Another article on Wechsler and Raven's with autism
For those interested in the research by Michelle Dawson and her group on assessing intelligence in autistics on the Raven's versus the Wechsler, I have just found out that one of the IMFAR abstracts that dealt with the issue of the Raven's in autistics has actually been published online. The article is here Though I may have beaten this issue to death somewhat lately, I was interested to find out that this was not just a conference abstract but an article that was actually available online, and I have just read the entire article and found it interesting. Testing was done on a group of autistic children and children with other disorders as well as typical controls. The autistic group scored higher on the Raven's than on the Wechsler. However, the high scores were just specific to the lower functioning group (lower functioning being defined as having a full scale IQ of less than 85) who scored about 20 IQ points higher on the Raven's than on the Wechsler. There was no difference between the two tests in the group of higher functioning autistics. I won't comment further but I just thought that everyone who, like myself, has an interest in the work the Mottron lab has done on intelligence in the Ravens versus Wechsler might like to read this article.
