Primary auditory stream segregation and perception of order in rapid sequences of tones.

Abstract

Examined the finding by R. Warren, C. Obusek, R. Farmer, and R. Warren (see record) that listeners were unable to judge the order of 3 or 4 nonspeech sounds presented in a repetitive cycle. 2 experiments with 32 and 21 undergraduates show that at high presentation rates of a short cycle of 3 high and 3 low tones, Ss invariably segregated the tone sequences into streams based on frequency and could perceive only those patterns relating elements of the same subjective stream.
