I know that certain variables can be passed from Qualtrics to Pavlovia and then back to Qualtrics by inserting them in the URL, like participant ID. However, I want a variable generated within the PsychoJS task (e.g. RT, the average response time of a certain block of trials) to be passed to Qualtrics for later use. Is that feasible? If yes, then how?
Any comment is appreciated!
