Pattern Specificity in the Effect of Prior [delta]f on Auditory Stream Segregation
Snyder, Joel S.; Weintraub, David M.
Journal of Experimental Psychology: Human Perception and Performance, v37 n5 p1649-1656 Oct 2011
During repeating sequences of low (A) and high (B) tones, perception of two separate streams ("streaming") increases with greater frequency separation ([delta]f) between the A and B tones; in contrast, a prior context with large [delta]f results in less streaming during a subsequent test pattern. The purpose of the present study was to investigate what aspects of the context pattern are necessary for this context effect to occur. Simply changing the B-tone frequency without an alternating A tone present was not sufficient to cause the effect of prior [delta]f, but rather a melodic change between A and B tones was necessary. We further investigated the extent to which the context and test patterns needed to have similar rhythms (xxx-xxx-) and melodies (up-down-flat-up-down), and found that a maximal prior-[delta]f effect occurred when the rhythmic patterns of the context and test were similar, regardless of the melodic structure. Thus, the effect of prior [delta]f on streaming depended on the presence of (1) at least one melodic change in the context, and (2) similar rhythmic patterns in the context and test.
