The glissando illusion is another example of hearing a tone as coming from high in space when its pitch is high and low in space when its pitch is low. In listening to this illusion, many listeners hear this glissando as moving between left and
right in space as its pitch moves between high and low, and at the same time moving between high in space when its pitch is highest and low in space when its pitch is lowest. In our experiment, many right-handers heard the glissando as tracing an elliptical
path aligned diagonally between a position low and to the left when its pitch was lowest and high and to the right when its pitch was highest. See the drawing by a listener on Fig. 4 of this article:
Deutsch, D., Hamaoui, K., and Henthorn, T. The glissando illusion and handedness. Neuropsychologica 2007, 45, 2981-2988. The sound example can be heard from http://deutsch.ucsd.edu/psychology/pages.php?i=205 and is heard best with sounds presented via stereo loudspeakers. Cheers, Diana |
