For questions about jsPsych the preferred method of support is the jsPsych Google group. Questions are most likely to be answered when they include a reproducible example of the problem. If you can make your code available online and link to the experiment, that will make the question easier to answer.

If you have identified a problem with jsPsych, such as a bug in the code or an error in the documentation, please open a new issue on the GitHub site.

Inquiries for paid consultation to develop experiments using jsPsych or to create new custom jsPsych features can be sent to
