Subject: unattended streams From: Bob Carlyon <bob.carlyon(at)MRC-CBU.CAM.AC.UK> Date: Sun, 27 May 2001 15:49:13 +0100hi, I haven't been following the list's exchanges on this topic but was woken up by the subject line on al bregman's recent posting, and spotted his request for an online version of my work. Unfortunately there isn't one, but the article in question has been published as: R.P. Carlyon, R. Cusack, J.M. Foxton, and I.H. Robertson (2001). "Effects of attention and unilateral neglect on auditory stream segregation", Journal of Experimental Psychology: Human Perception and Performance, 27, 115-127. I am happy of course to mail reprints, or to email a Word version of the article In terms of reconciling our results with other findings, I would say the following: What we did was to give subjects a demanding auditory task in one ear during the 1st 10 seconds of a streaming sequence presented to the opposite ear. When subjects switched attention to the streaming sequence they reported much less segregation than in a task where they attended to the streaming sequence throughout. This shows that diverting attention can greatly reduce the build-up of streaming. However, a less demanding task (or perhaps one in another modality) may allow SOME streaming to build up. regards bob carlyon Dr. Bob Carlyon MRC Cognition and Brain Sciences Unit 15 Chaucer Rd.
