My first time attempting to use Prolific with Inquisit Web and have run into a problem. Clearly, I am doing something wrong and was hoping you all might be able to easily help me.
Almost all prospective participants are getting this message: I clicked the link to launch the study and a little window appeared telling me to download the Inquisit Webplayer. I clicked the link to download and after that I clicked on the download folder. I got a pop-up saying "The Inquisit 4 Web player was successfully installed". Then when I went to click start I got a pop-up saying "Failed to get subject id. The url has no parameters".
I suspect something is amiss for me on Inquisit's set-up were I enter info for Participants Ids. There I selected "URL Parameter" and then "subjectid." For group I entered "URL Parameter" and "groupid." I assume the issue is with the former, but am not certain (it's a repeated measures design, not B/t Ss so the groupid part doesn't matter). On another set-up page, I redirect Ps to Prolific's site with the URL they provide me. (In case this matters, since I was not confident with how to handle subject ids embedded within either system , I simply asked Ps to enter their Prolific ID within the demographic section of the inquisit script at the end of the study).
I appreciate the help! Thanks.
