Developing your experiment
Uploading your experiment to JATOS
Once you have developed your experiment, you export it from OpenSesame and upload it to JATOS. JATOS is a web server that manages experiments: it allows you to generate links that you can distribute participants, and it stores data that has been collected.
There is not a single JATOS server. Rather, many institutions maintain their own JATOS server. In addition, https://mindprobe.eu is a free JATOS server, sponsored by ESCoP and OpenSesame.
One you have uploaded your experiment to JATOS, you can start collecting data. You can do this by manually sending links to participants, for example through email. Or you can use a platform for participant recruitment, such as Prolific, Mechanical Turk, or Sona Systems.
