Description of the problem:
Having finally got the task working online, I excitedly put it up on Prolific to start collecting data.
30% of my participants were unable to complete the task. There were separate problems being reported.
First, some people did not get past the “Initialising the experiment screen”. It just froze there. Second, people experienced a crash or random freeze. There seems to be no consistency in which part of the task it happened. Some made it all the way to the very end before it crashed, others crashed near the beginning, yet others somewhere in the middle. Some people described the crash as a frozen screen, some said the window went black.
I asked them all which browser and operating system they were using and all of them were using Windows 10 and either Chrome or Edge as browsers.
This is really frustrating because for those who made it part way through the task we obviously have to pay them, and we get no data at all when it crashes. Luckily I was only collecting a small sample of 25 people, but my next step is to scale it up to the hundreds. There is no way I feel comfortable doing that at the moment.
I not that a similar question was raised recently with no reply: Online study crashes on Windows Chrome
After all the effort that’s gone into getting this ready, I really don’t want to have to ditch psychopy and code my task in a different platform.
Does anyone have any idea what could be happening and how to address these issues when they don’t occur on the machine I’ve developed the task on?
