Hi,

For my task, I will randomize 6 trials with 2 sliders in each. Sliders in different trials have different labels.

I tried to set the label in each slider referring to the value in the condition file, but an error message indicated that the parameter is not define. Does anyone know how I can display the labels differently in different trials and randomly present them to participants? Many thanks!

If you have the same number of labels each time, you could do this: # Get labels list for this routine labels = efflabels.split(",") # For each label... for i, obj in enumerate(mySlider.labelObjs): # ...set its text to be the corresponding value in labels, and store this in the slider obj.text = mySlider.labels[i] = labels[i] (the initial value of labels would need to be the same number of values as in efflabels sepa…
