--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.
