Method-of-adjustment with facial expressions

Hi all,

I’m trying to run one offline experiment with method of adjustment in Psychopy Builder so that the observer changes the emotional intensity of a probe face with the right and left keys. I don’t know what function I should use and how. Does anyone know about it?

Thank you in advance for your great help!

Do you have a set of images with different emotional intensities for each probe face? If so, then this sounds like a visual version of my tone selection demo.

Thanks for your great help! Already fixed the problem.
