Subject: simple up-down: is there an original reference? From: Massimo Grassi <massimo.grassi@xxxxxxxx> Date: Wed, 14 Nov 2007 12:48:57 +0100 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Dear list, I always been told that von Békésy was the first to use (or the inventor of) the "simple up-down" staircase. Is there a precise reference for it? I checked more than a dozen of articles by now, but everybody seems to sweep this problem under the rug. Perhaps because there is not such a reference? m -- Massimo Grassi - PhD Dipartimento di Psicologia Generale Via Venezia 8 - 35131 Padova - Italy http://www.psy.unipd.it/~grassi http://percezione.wordpress.com/
