Unfortunately, I expect this sort of thing to be difficult to deliberately test an individual on, because if someone goes in knowing what’s being tested, or figures it out from the test, it’s going to alter the results beyond use. Self-testing may not be possible at all.
I recall having read about blind studies being done on related topics but, alas, I am terrible about keeping organized links to such things.
