I’m trying to provide an example of how a sequence of images should be rated by having the slider marker move automatically according to the correct ratings.
In the PsychoPy version I just added:
slider.markerPos = rating[currentImage]
which worked well.
But on the online version I get this error:
- TypeError: Cannot set properties of undefined (setting ‘markerPos’)
From what I understand, markerPos is undefined until there’s a click on the slider. Is there any other solution for making the slider marker move without the participant interacting with the slider at all?
