Randomize the position of multiple rating scales

Hey everyone!

In the experiment I’m putting together, I need to include a page where there are multiple rating scales for photographs. I’d like to know whether I can randomize the position of these scales so that participants are not always responding to them in the same order. The scales are all fairly similar (1-10, mostly), though I’m not sure if that should really make a difference. I haven’t really tried much yet, just figured I’d ask.

The position field in the builder component accepts a variable as input. You can therefore add an excel file as a conditions file to the surrounding TrialHandler, which contains different combinations of positions for your scale. The TrialHandler does the randomisation for you.

does it work for now?
