Subject: Higher thresholds = steeper slopes? From: Brian Gygi <bgygi@xxxxxxxx> Date: Sat, 4 Aug 2012 13:00:48 +0000 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>----=_vm_0011_W8499420846_10053_1344085248 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable Hi, I have some data for normal and hearing-imparied listeners for 90 AF= C identification task for which the psychometric functions for the HI lis= teners have significantly steeper slopes than for the normal-hearing ones= , even though their thresholds are higher. Is this a common finding in th= e psychophysical literaure, or related to the nature of the hearing impai= rment, namely that once they can hear it, they rapidly achieve perfect pe= rformance (somewhat similar to the growth of loudness functions). Thanks for any leads on this, Brian Gygi ----=_vm_0011_W8499420846_10053_1344085248 Content-Type: text/html; charset="utf-8" Content-Transfer-Encoding: quoted-printable <html><body bgcolor=3D"#ffffff"><div><font face=3D"Verdana" size=3D"2"><= /font></div> <div><font face=3D"Verdana" size=3D"2"> Hi, I have some data for nor= mal and hearing-imparied listeners for 90 AFC identification task for whi= ch the psychometric functions for the HI listeners have significantly ste= eper slopes than for the normal-hearing ones, even though their threshold= s are higher.
