>>11717742Pattern matching is one way of testing. If you look at a WAIS instead of an RPM, which is probably what you're thinking of, there isn't much pattern matching going on there.
You're looking for this thing called "g", basically all you do is make a battery of tests, any type of tests as long as they aren't too specialized or trivial, and rank order the takers based on how many items they answered correctly. The result is always that your score on one test is about how you do on all the other tests, regardless of whether your performance was extreme or average.
You may think that when you see a vocabulary section on the WAIS that word knowledge is a trivial skill. The idea behind that is that, if testing the subject's first language, you're sampling something called "crystallized intelligence", and while that is in a sense trivial, everyone has a use for their first language and better functioning minds are more likely to successfully collect and retain information about it.
Whether or not that's precisely true, tests with items like that will give you almost the exact same score as one that is purely spatial pattern matching (when controlling for the test's reliability with itself, about .87), unless you have a relative cognitive disability somewhere.
