N1 - Turgeon was first and lead author. She originated the questions and design, collected and analysed the data, and wrote the manuscript. She presented the results at the ASA meeting in 1999, at the 6th ICMPC in 2000 and at the New York Academy of Science Meeting 'Biological Foundations of Music' in 2000.

N2 - The rhythm created by spacing a series of brief tones in a regular pattern can be disguised by interleaving identical distractors at irregular intervals. The disguised rhythm can be unmasked if the distractors are allocated to a separate stream from the rhythm by integration with temporally overlapping captors. Listeners identified which of 2 rhythms was presented, and the accuracy and rated clarity of their judgment was used to estimate the fusion of the distractors and captors. The extent of fusion depended primarily on onset asynchrony and degree of temporal overlap. Harmonic relations had some influence, but only an extreme difference in spatial location was effective (dichotic presentation). Both preattentive and attentionally driven processes governed performance. (PsycINFO Database Record (c) 2007 APA, all rights reserved)
