Hello Nick, No you didn’t imagine this study – but indeed it was a few decades ago! Wallach, H. (1940). The role of head movements and vestibular and visual cues in sound localization.
Journal of Experimental Psychology, 27(4), 339–368. http://doi.org/10.1037/h0054629 The paper is also one of the first to make the interesting claim that perceived auditory motion is subject to prior expectations that
relate to the statistics of the world – in this case, that most objects are at rest. Much has been made of the slow-motion prior to explain many visual motion illusions in the context of Bayesian models (indeed, the use of priors has been extended to a whole
variety of visual phenomena in areas other than perceived motion). My understanding is that this type of approach has received less press in hearing science.

[mailto:AUDITORY@xxxxxxxxxxxxxxx] On Behalf Of Smith, Nicholas A. I was hoping to get a pointer to reference to an old auditory localization study that I remember hearing about in an undergrad lecture (my impression was that it was an old study, back when I was an undergrad
in the 1990’s), but has stuck with me all these year because it’s clever and cool. As I remember it, subjects were seat on a stool within a large cylinder. The walls of the cylinder were made of acoustically transparent canvas or burlap, on which vertical black and white stripes were painted.
There was a loudspeaker directly in front of them, but outside the cylinder so it could be heard but not seen. The cylinder rotated slowly to induce the illusion of motion (subjects felt that they themselves were rotating within a stationary cylinder). When
asked where the sound was coming from, they indicated that it was directly above, the only location in which interaural intensity and timing cues would be constant, if they were indeed rotating. Assuming I didn’t imagine this study, I’d love to talk about this demonstration with my students, but I need more to go on than my sketchy memories. Thanks in advance, Nick
