I have been running a Matlab code, written by a colleague, that uses quest.

I want to check the quest results for some of the subjects who showed abnormal results to see if they in fact approached or reached a threshold level, or if they oscillated widely throughout the trial, never really converging to a threshold level.

Is there an easy way to visualize this data? Thanks in advance! I have never used quest before

Hi! I came upon your question because am looking for a similar answer. I am using Quest and want to restrict the range of the stimulus intensities suggested by Quest. In Quest Demo they mention that it is possible, but do not specify how :). Did you use Quest and would you have a recommendation? Would it be perhaps possible to see your code as you used it? Thanks! Andra
