Description of the problem: I recruit participants on prolific. Lately, I’ve been getting in my opinion too many messages saying that they completed almost the entire experiment but then the site (pavlovia) crashed and asked them to start the experiment all over again. Of course the idea here is that they should be compensated. Does pavlovia ask to start the experiment again? Or is this a trick? Thank you!
I don’t use anything that’s memory heavy. I only show numbers and geometric figures drawn on the screen to which participants have to react by pressing a button. I also don’t save partial data.
Some participants report that the page crashed showing ‘initializing experiment’, which I can more readily believe because I’ve seen this message myself when I start the experiment online after pushing some changes to pavlovia (gitlab). Apparently addblock can cause a problem, at least in the initializing experiment case. But there is probably also other reasons.
Also what I noticed in the past 2 days is that changes that I push to pavlovia don’t show up until I delete cache in my browser. I assume they’re being pushed fine, it’s just how it interacts with the browser. This seemed to already happen at some point in the past. Maybe this has something to do with the task crashing, idk.
No, I don’t have anything like that and I don’t use an ad blocker on my computer. I’ll look into upgrading, thank you! But right now I’m in the middle of data collection, so I don’t want to change halfway through.
I collect my data in batches and after every batch there are some credits on pavlovia that remain reserved long after all participants have finished the task. I still have enough credits left for all participants, but maybe this is some sign that something is going wrong in the communication between the server and their computers.
