Apologies Olivia, this is a new feature we rolled out a few days ago, so I was a bit confused earlier.
Here are all the details you need:
The idea is to make the review process quicker by flagging participants that have failed attention checks.
When you set up your study you will still need to put in the completion code URL to redirect your participants back to the Prolific website, as you have done in your previous studies.
Now, however, you also have the option to add a second URL which automatically ends the study if a participant fails two attention checks, directly after they have failed the second check.
These participants will be easily identifiable on the submissions page making it easier for you to spot them. Please, still ensure your attention checks are fair before rejecting participants.
If you would prefer, you do not need to use this feature and can just leave the box blank. This will mean that you manually check for failed attention checks at the end of your study by reviewing the submissions, as you will have previously done.
Essentially, if your programme logic isn’t compatible with this new system, then there’s no need to use it
Sorry for the earlier confusion. Let me know if I can clarify anything further
