limit size of items used
Hello,
I have send email to the people listed on JATOS website. But i need answer quickly as possible so I am posting copy of that email here someone has answer.
I am new to JATOS/jsPsych and how it works. I have been testing a script that shows only picture and click button and move to next picture and so on. But later, I want to change the script to add mixture of pictures, vidoes and play audio with each one and move to next one automatically.
What is the limit Jatos (with JsPysch) can handle in total GB or KB of items until it gives error loading or please wait while we load message?
For example: I am familiar with PCIbex. If I put 50 images with audio, maybe runs fine but as I keep adding more and more picture and audio, eventually I get please wait while we load message. (everything move to next item automatically)
Same with videos, i can upload maybe 20 to 30 videos (depending on size) until I start to get please wait while we load the items message (sometime continues or stuck there).
Will this be a problem with JATOS experiment? I have tested a script with 37 images and it worked well.
Since I cannot figure out how to add audio and video in the script, I have not been to test to see if this causes loading issue.
Thank you

Tested the 37 images in Jatos script.
There is a difference between JATOS and tools like PCIbex. While PCIbex tries to solve the whole problem of doing online experiments, including building and delivering it, JATOS just concentrates on the delivering part and leaves the building part to other tools. You already use jsPsych for the building part, but there are others (like lab.js) or you can also just write your experiment yourself in JavaScript/HTML/CSS.
In your case, loading many pictures and videos, JATOS is not so much the limiting factor, but the experiment's programming (the building tool), the participant's browser, your server machine and the internet connection. JATOS just delivers the files and there is no upper limit or the limit is what your server machine and internet connection is capable of.
What I'm trying to say is, that you can definitely do what you aim for with JATOS, but you should check all the other factors. But there I can't really help you because I do not have enough information about your experiment and the possibilities and combinations are vast.
I wish you good luck with your experiment.
