Help: need citations for scientific experiments on comma shifts or similar

Hi,

I'm hoping to actually undertake controlled scientific study of perception of comma shifts in certain contexts. My goal is to clarify specific things about who notices comma shifts in what contexts. I wanted to get to something about the significance of the issue, but I just need to focus on something small for a rigorous experiment to meet scientific ideals.

I'm hoping to get some pointers on research already done and published in journals. Though I'll accept other citations, I'm looking for examples of controlled studies done with multiple subjects and submitted to statistical analysis. Anything that relates to tuning and temperament.

I've read a lot of the literature on cultural systems, history, theory, and also on psychoacoustics (general issues of beats, combination tones, etc.), but I haven't seen anything with controlled subject-based studies focusing on tuning issues.

In a more open sense, I'm interested in any opinions about what citations I should or shouldn't use in my experimental design proposal.

For the record: I have not gotten around to reading the many back issues of journals like Music Perception. I have read a large number of the standard books in the areas of tuning etc. I'm just in the process of trying to get more into the official academic side of all this stuff, especially from a scientific psychological experimental perspective rather than only a musicology/music-theory perspective.

Thanks,
