PERCEPTUAL ORGANIZATION IN A COMODULATION MASKING RELEASE INTERFERENCE PARADIGM - EXPLORING THE ROLE OF AMPLITUDE-MODULATION, FREQUENCY-MODULATION, AND HARMONICITY

Two areas of interest within auditory scene analysis are the identification of cues which contribute to auditory grouping and/or Segregation, and the methodology employed to measure such effects. The present study explored the roles of three purported grouping cues-correlated AM, correlated FM, and harmonicity-using a comodulation masking release interference paradigm. This method was reasoned to be free of alterations in the subject's mode of listening (analytic versus synthetic). The results suggested that correlated AM was a viable grouping cue. For some listeners, the presence of FM also appeared to provide a grouping cue, but, generally, no effect of coherence of FM was observed. No effect of harmonicity was observed in this paradigm. © 1995, Acoustical Society of America. All rights reserved.
