Multiple Interleaved Staircases


I am creating a typical Posner cueing experiment (valid, invalid and neutral cues). I would like to have three different interleaved staircases parallelly, so that depending on the trial type the staircase will be valid, invalid or neutral and thus the fluctuations in target contrast will change independently for each trial type. Is this possible with PsychoPy? Any examples?


I am actually finding a potential way to do this with MultiStairHandler. However, when I add new data with .addOtherData() they are not saved in the csv file. May there be some bugs in the source code?
