To Auditory List The kind of streaming that Pierre Divenyi is writing about, based on parameters such as loudness or timbre, was studied by Douglas Johnson and myself. The reference is "Stream Segregation and Peripheral Channeling," Music Perception volume 9, number 2 pages 155-184 (1991). We used an interleaved melody paradigm and studied streaming caused by ten different kinds of parameter changes. The data showed that those parameter changes which led to peripheral channeling were effective in creating stream segregation. Those changes that did not separate melodies according to simple trajectories in the periphery did not lead to streaming. Bill Hartmann
