Subject: i-pad app for Stroop test From: Vidya Krull <vkrull@xxxxxxxx> Date: Mon, 17 Sep 2012 09:05:27 -0400 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--047d7b4190316deabd04c9e56d5d Content-Type: text/plain; charset=ISO-8859-1 Dear List, Does anyone know of or has used a reliable iPad app for the Stroop test? I found a couple online, but they seem to be developed more as games and are not feasible for experimental use. I am looking for something that allows the experimenter to control the number of trials, and scores congruent and incongruent trials separately. Thank you in advance for any suggestions.
