ABSTRACT
The following topics are reviewed: (1) The recent resurgence of interest in perceptual organization. (2) The types of research on auditory perceptual organization: stream segregation and concurrent pitch segregation (CPS). An introduction to the techniques of CPS. (3) The structure of Gestalts; their decomposition into parts, operations, a medium, and a perceptual outcome. Analogies between vision and audition with respect to perceptual organization and the concept of Indispensable Attributes: the organizational medium of pitch in audition is roughly analogous to the medium of space in vision. (4) Research in auditory perceptual organization introduces new concepts to psychoacoustics: Segregation by inter-aural time disparity as an example of successive-difference and concurrent-difference segregation cues and techniques for unconfounding them. (5) A review of Treisman s feature integration theory. The auditory system is shown to behave similarly to the visual system in this respect: concurrent pitch segregation cannot be caused by conjunctions of segregation cues.
