Hello, I’m currently running a single-interval, 2-alternative forced choice depth discrimination paradigm. In each trial, a standard and a test stimulus are presented simultaneously using Method of Constant stimuli (NOT adaptive staircase due to constraints with creating the stimuli).
I have set this up in the PsychoPy Builder.
I would like to obtain PSE thresholds/ JNDs etc.
Is there an easy way to do this in PsychoPy?
I can see that you can get these values out if I were using staircase/adaptive methods. I am new to PsychoPy and also new to Python, so I am struggling with trialhandler code or adapting Quest. Just wondering if I have missed seeing a really obvious function/something to extract thresholds? Can anyone help me with this? At the moment I am thinking to send the data to Matlab to process, but this defeats the reason that I was using PsychoPy in the first place (user friendly for undergrads to run exp).
Kind regards, Kirsten.
