Hi everyone who runs auditory experiments on Pavlovia,
If you want to make sure that your online participants are listening to your stimuli through headphones, try our online headphone check test using dichotic pitch stimuli. You can find more details about this test in our paper published on Behavior Research Methods.
I also made a website to update the PsychoJS code for you to attach the headphone test right before starting your experiment. Instructions are included.
Add a Headphones Check to your study here:
Headphones Check - Integration with Pavlovia/PsychoJS
The website can customise the test for you, and you can choose one of three headphone tests for your purpose. Check our github page: Headphone screen using Huggins Pitch | HeadphoneCheck_Test
