I have a set of experiments hosted on Pavlovia, and I want to make sure that these experiments are only completed by a selected (personally invited) group of participants. In other words, I want to eliminate the possibility that any invited participant could share the experiment with others by copying the URL.
Some things that I’ve already considered:
- Adding an entry code/password to the study, such that participants must enter the code to begin the experiment. This would not work because the code would be sharable, as well as the experiment URL.
- Hosting the experiment through an external platform such as MTurk or Prolific. This would not work because the URL of the study would still be sharable.
Is there any kind of method in place to handle this?
