Well, um, sighted differences DO result in different experience, and if we accept that neurochemistry (and biochemistry) create conciousness, we have to assume that there is a chemical as well as an "imagined" difference. (I think dualism discussions belong in the philosophy asylum, yes?)

I don't think that anyone would even think to suggest that physical or mental state would affect a subject's answers. One of the tricks to a good test is to create a comfortable state where the subject can control it to the extend that they can relax and do a good job.

Thing is, if you remember something, you DO remember the difference, no matter if it was or wasn't there. I think "imagined" is not the right word, because it's not a concious thing, or a deliberate thing, or even a subconcious thing, it's probability, plain and simple, that can create the start of a 'difference'.

Even if you just refocus your attention on a sound, say when somebody says 'isn't that cymbal harsh' you WILL remember different things, because you extracted different things. What may well depend on if you like or dislike the cymbal, for instance, you may argue that "no, it's not harsh, it's realistic" or "eww, that sounds like a load of dropped plates", depending on your expectation and pretty much anything under the sun.

This goes to explain again why a DBT is necessary. You really want the subject's response, not somebody else's.

Now, thinking one is getting a painkiller has been shown to release endorphins. These act the same (although not as powerful, usually) as opiates. Literally the same neural receptors, and narcan or whatever will block those receptors. So this isn't surprising, either.

Placebos do very certainly create physical differences at least some times when the person accepts that the placebo is real.
