Visual Analog Scale Question

Hello All,

First time posting a question so feel free to give advice or critique! I have a question regarding Rating Scales in PsychoPY. I need to prevent the participant in my experiment from receiving any visual feedback from the scale so I need to customize the ‘marker’ in such a way that it is not visible. It appears to me that making the ‘marker’ ‘grey’ appears to hide most of it but I want a more elegant way of removing it. Does anyone know a way to remove the marker or make it so small that it is invisible to the naked eye?

This is the settings for my Visual Analog Scale currently.

scale= None,
pos=[0.0, -0.2],
labels= (‘very weak’, ‘very strong’),
marker= ‘circle’,
markerColor= ‘grey’,

Thanks in advance,
Michael Bacallao

I think the easiest way would be to add a code component above your rating scale in builder and add the following in the every frame window:

rating.marker.opacity = 0

Best wishes,

Thanks Oli,

It took me a minute to figure out that i needed to rename the “rating” part of your script but otherwise that worked perfectly, thanks.
