Subject: [AUDITORY] Question about criterion in 2AFC designs. From: Sam Mathias <smathias@xxxxxxxx> Date: Sun, 15 Sep 2013 09:56:58 -0400 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--089e0115eef816028b04e66c763f Content-Type: text/plain; charset=ISO-8859-1 Dear list, I think I know the answer to this question, but I'd rather be totally sure. When calculating sensitivity (d') in a 2AFC experiment, one needs to apply the sqrt(2) correction to the standard YN equation. My question is whether the same correction needs to be applied when calculating the criterion (c) in 2AFC. Many thanks, -- Dr. Samuel R.
