Auditory saltation: A new measure for an old illusion

Auditory saltation is a mislocalization phenomenon in which click trains presented successively at two discrete spatial locations appear to originate from a smoothly varying series of source locations spanning the true source locations. The temporal parameters of this illusion are investigated with click stimuli delivered via headphones with the goal of establishing a portable test of the illusion. A simple rating scale was developed which required human participants to indicate the degree to which the perceived sound locations were heard as continuous (evenly distributed across space) versus discontinuous. Control conditions were devised to provide a baseline against which to compare the illusion. Auditory saltation is discussed in terms of perceptual grouping.
