The implementation of the "newer SAT reasoning test" seems to have been just a rename, at least at the time of the name change. From the encycwopedia:
In 1993 de name was changed to SAT I: Reasoning Test (wif de wetters not standing for anyding) to distinguish it from de SAT II: Subject Tests.[34] This change was instituted because of sharp criticism and wongitudinaw studies showing dat de originaw meaning was no wonger accurate; de SAT did not accuratewy measure what it said it was measuring.[citation needed] In 2004, de roman numeraws on bof tests were dropped, and de SAT I was renamed de SAT Reasoning Test.
Did the basic nature of the SAT change recently? Although the SAT has certainly had changes, I wouldn't jump to a conclusion that the IQ correlation results are invawwid because of the changes.
What I was looking at was the 2005 update -- the time at which it became what is often referred to as the "new SAT." From the wiki article quoted above:
2005 changes:
In 2005, the test was changed again, largely in response to criticism by the University of California system.[30] Because of issues concerning ambiguous questions, especially analogies, certain types of questions were eliminated (the analogies from the verbal and quantitative comparisons from the Math section). The test was made marginally harder, as a corrective to the rising number of perfect scores. A new writing section, with an essay, based on the former SAT II Writing Subject Test, was added,[31] in part to increase the chances of closing the opening gap between the highest and midrange scores. Other factors included the desire to test the writing ability of each student; hence the essay. The New SAT (known as the SAT Reasoning Test) was first offered on March 12, 2005, after the last administration of the "old" SAT in January 2005.
The research that correlates IQ with SAT scores was all looking at administrations of the test prior to the 2005 changes. My understanding was that things like the analogies, which were removed in 2005, were the parts that were the most g correlated on the SAT. I took a psychometrics class a few years back at a local university as well in which the professor, a psychometrician, said that the new SAT (2005 and later) was more similar to the ACT and no longer considered a test of aptitude or ability.
