Experiment won't play, stuck on "initializing" in Pavlovia

OS (e.g. Win10): MacOS 10.15.3
PsychoPy version (e.g. 1.84.x): 2020.2.5
Standard Standalone? (y/n) If not then what?: y

Hello! I am a beginner in Psychopy and I’m helping to work on an attentional bias experiment. My issue is that when I play the experiment within Psychopy it opens to a black screen and then quits with no error message. I tried importing into Pavlovia with the hopes that it would work further but when I try to pilot it there I get a “Initializing” message that persists for long periods of time.

The experiment can be viewed on pavlovia here: Emily Perelman / attentional-bias · GitLab and I am attaching a photo of the structure below.

Thank you so much and I appreciate all recommendations!

Hi There,

There are several threads on the forum relating to the ‘initializing experiment’ page and how to approach this situation.


May I recommend that you consult these pages, from there you will be able to retrieve a more specific error message that will be more helpful for problem solving and seeking help.


Thank you! I had a a blank text field so the first thread helped me solve that!


great - pleased you found your solution !:slight_smile:
