LOL.
I mentioned this in response to your "questionable, from a psychological perspective" comment, only to point out that there's a limit to the quality of research we can expect in this area. I don't have issues with anyone's trivial pursuits...obviously I'm interested enough in the sound of power cords to be talking about it here, and I design banner ads for a living!
Exactly, I just pointed out that such kind of tests are hardly 'scientific' or 'definitive', the more when one comes to investigate the mental processes, there's no general consensus among scientists.
Basically I don't buy the 'I can't measure it, ergo it doesn't exist' argument, nor the 'I can hear it, ergo it exists' argument. That it's more or less like the old philosophical matter that people smarter then me, like Hume, Locke or Dewey, just to name a fews never solved. Actually I was only making some college level philosophy starting from power chords.
Sorry for the misunderstanding.
