Dear Chris, I would like to get a copy of your paper. Seems pretty
intersting.
Thanks in advance

> ABSTRACT
> 
> The octave illusion is elicited by a sequence of tones presented to each ear
> that continuously alternate in frequency by one octave, but with high and low
> frequencies always in different ears. The percept for most listeners is a high
> pitch in one ear alternating with a low pitch in the other ear. The
> influential 'suppression model' of the illusion proposed by Deutsch and Roll
> (1976) carries three postulates: first, that listeners perceive only the pitch
> of the tones presented to their dominant ear; second, that this pitch is heard
> in whichever ear received the higher frequency tone; and third, that this
> apparent dissociation between "what" and "where" mechanisms arises from
> sequential interactions between the tones. In the present article, we
> reappraise evidence for the suppression model and demonstrate (a) the
> incompatibility of the theory with existing literature on pitch perception,
> sound localization and ear dominance; and (b) methodological limitations in
> studies that have claimed to provide support for the suppression model. We
> conclude by proposing an alternative theory of the octave illusion that is
> based on established principles of fusion, rather than suppression, between
> ears.
