Subject: addendum to my query about 7+/-2. From: Chuck Watson <WATSON(at)UCS.INDIANA.EDU> Date: Tue, 10 Aug 1993 15:06:17 ESTI guess I'm getting too old. I had thought the Pollack papers were so well known that you'd all have them in a file... anyway, since there were requests for those references: Pollack, Irwin (1952) The information of elementary auditory displays. J. Acoust. Soc. Am. 24, 745-749. Pollack, Irwin (1953) The information of elementary auditory displays. JASA, 25, 765-769. Pollack, Irwin (1956) Identification and discrimination of elementary auditory displays. JASA, 28, 906-909. two of our papers that we think are at least distantly relevant to the issue are: Watson, C.S., Foyle, D.C. and Kidd, G.R. (1990) Limited processing capacity for auditory discrimination. JASA, 88, 2631-2638. Kidd, G.R. and Watson, C.S.(1992) The "proportion-of-the-total-duration rule" for the discrimination of auditory patterns. JASA, 92, 3109-3118. Thanks for the quick responses.... Chuck
