Description of the problem:
We have two attention check questions – if a participant gets either of them wrong, it essentially terminates the experiment. The issue is that we want to 1) get access to the participant ID if a participant fails the attention check so they dont redo study and 2) get this information without using a Pavlovia credit.
In our initial studies, we had over 35% of our Mturk participants fail these checks. Even if we dont pay them for their participation, using these Pavlovia credits is costly with many participants. We now have it so, if they fail, it sends them to red screen that says “you failed attention check”. It then asks them to exit the program so we dont use a Pavlovia credit. However, now we can’t store their participant ID with the rest of the completed data files.
Our current work around is that we have them enter their ID before starting the Pavlovia experiment, so we can at least see if the participant tried to do the experiment at some point (but dont know if they just stopped or if they were booted because they failed the attention check). But it’s not optimal to try to verify things this way.
Is there any solution to this issue? That is, can we get a data file with their ID number without having to use the credit? Or if we want to verify they failed the check, we just have to suck it up and pay for it?
