Standard Standalone? (y)
I’m trying to convert a simple staircase I have been using into a QUEST staircase. My first question is what is the difference between the two options in the loop in builder (QUEST vs quest)?.
My next question is more specific. I have a 100 step continuum (between two speech sounds) and I'm starting people off at the 1/2-way point (50). So I set the startVal at 50 and the minVal at 1 and the maxVal at 100. I also set the range at 99 (difference between maxVal and minVal) and the StartValSd at 15. Since I want to find the boundary between the two sounds, I set the pThreshold to 0.5. I immediately get an error saying "psychometric function range [0.5 0.99] omits 0.50 threshold" I assume I'm misunderstanding the units involved, but I don't know which parameters I'm misinterpreting. Thanks! Mark
