I am using Prolific for my study, which first involves a Pavlovia Survey, and then involves a Pavlovia (PsychoPy) experiment. My Prolific ID will pass through the Pavlovia Survey URL, but disappears when I get to the PsychoPy experiment. What is incorrect about my URL parameter usage?
Here is the format of my completion link of the Pavlovia survey, which leads to my Pavlovia experiment.
‘WHStories [PsychoPy]’ + {%PROLIFIC_PID%}
I also have a parameter that I created in the Builder’s experiment info section, where participant = {%PROLIFIC_PID%} .
