I'm skeptical of people's ability to self-report things that affect them in subtle and not-entirely-conscious ways. For instance, take a major scale played by a monophonic synthesizer of some kind. I know that a major scale in 12-tone equal temperament differs substantially from a major scale in just intonation. (The thirds and sixths are all off in various directions by about 13-15 cents.) I know that if I play such an instrument in equal temperament I'll get bored/annoyed with it sooner. At the same time, if I listen to a major scale in equal temperament and just intonation, I probably won't be able to tell you which one is which even though I know they're quite different. (In a chord the difference is much more obvious.)
