it's no easy task to evaluate distance perception under anechoic

By the way, I think that is one of the reasons anechoic rooms are
perceptually so overwhelming and induce the kind of anxiety they do: in
the absence of pretty much all meaningful distance cues, sound sources
sort of crawl up onto you skin, and the distance perception also becomes
rather unstable. I'm reasonably sure at least half of the "pushing",
"suffocating" or "anxious" feeling they give you comes from the illusion
that any and every sound source is violating your sphere of
privacy/autonomy. That's also why I've never really been happy when
people describe the sensation as being "sterile" -- to me it seems
rather the opposite.
We did this during my PhD research on WFS.
With the above in mind, do you know of any research into the purely
psychological and/or emotive aspects of anechoic conditions, and/or
other spatial distortions? Including at least WFS's spatial aliasing,
HOA's angular blurring, or, say, binaural/XTC related externalisation
effects ("in your head" and all that)?

Ooh, I don't think I have this one yet. Care to share a preprint?
Also, if people want, I could probably assume the risk over another
collection of papers in addition to the Ambisonic Motherlode, this time
pertaining to WFS. Perhaps even a third one, with discrete systems in
mind. If ya'll're game, private and/or anonymous submissions are
welcome.
Finally, right now I'm at least a year or so behind current Ambisonic
research as well. Any recent contributions to the Ambisonic 'lode would
be greatly appreciated; eventhough I still don't have the time or the
energy to organize it neatly.
