What are you trying to achieve?
I am trying to make a toy demo for a class. In the demo case, the participant is going to hear two tones. One high tone and one low tone. If the participant hears a high tone, then s/he presses f; If the participant hears a low tone, then s/he presses j.
I want to have an adaptive staircase, in which only the participant makes the correct response 90% of the time can s/he proceeds to the next phase.
What did you try to make it work?:
I am very confused by the instruction given by the adaptive staircase procedure.
I have made a loop using the standard “random” and everything works just fine. But I have no clue how to get started with staircase. When I tried to use default setting, PsychoPy will crash and give me the error message:
Traceback (most recent call last): File "/Users/caoanjie/Desktop/FALL2019/IMCR/IMCR_minimum/soundDemo_lastrun.py", line 389, in <module> if (key_trial.keys == str(ANS)) or (key_trial.keys == ANS): NameError: name 'ANS' is not defined
ANS is the column head in which I store my correct response in the condition file.
I assume this is due to the fact that in adaptive staircase scenario, psychopy doesn’t really read my condition excel file.
Is there a way for me to let PsychoPy know the correct response and make “adaptive staircase” based on the rate of correct response?
I’ve the flow of my experiment here:
