Stupid IQ test

Here is another in the series of IQ’s Corner “IQ Test CHC DNA Fingerprint” test comparison series.

Interesting article “in press” in Intelligence that compares WAIS and Stanford Binet IQ scores (across different editions except the current SB5 and WAIS-IV) for adults with intellectual disability (ID/MR).  Although the mixing together of scores across different editions makes it impossible to make SB/WAIS-specific edition comparisons, the finding that the WAIS scores were, on the average (mean), almost 17 points higher may surprise many psychologists.  The authors discuss the real-life implications (i.e., Atkins ID death penalty decisions; eligibility for SS benefits, etc.) of different scores from different tests.  As outlined in a prior IAP AP101 special report , differences of this magnitude between different IQ tests should not be surprising.  Silverman, W., Miezejeski, C., Ryan, R., Zigman, W., Krinsky-McHale & Urv, T.

IQ test selection could be life-or-death decision: WAIS v SB score differences in ID/MR sample

I ran a search of the ProQuest Digital Dissertation Database in search of studies involving the most recent versions of the WAIS-IV and WISC-IV .

[Note.

I should have included the following tables in my original AP101 Brief # 6 report re: my analysis of the CHC content of the FS IQ scores for the various editions of the WISC–WIS-IV/WAIS–WAIS-IV intelligence batteries.

I just posted a new online presentation at SlideShare summarizing a series of recent analyses I’ve completed.

Pushing the edge of CHC theory and the WJ III measurement envelope: Part I

The following are the first three paragraphs (and a critical figure) of a draft of an IAP Applied Psychometrics 101 Brief Report (#5).

I frequently reference the CHC (Cattell-Horn-Carroll) theory of intelligence and the impact it has had on contemporary intelligence test development.  I realize that not everyone has the time to rummage through all the blog posts I’ve made regarding CHC theory.  Thus, today I’m posting a brief summary of CHC theory and its impact on applied intelligence test development.  The summary includes hyperlinks to key references, terms, and other readings (for more indepth information).  The report can be viewed as a web page or can be downloaded or viewed as a PDF file .
