The 3.6.5 version is an upgraded PsyToolkit version with massive improvements and many small improvements under the hub. Lots of things work better. Sometimes small things, sometimes big things. For those of you with a Gmail account, you can now simply login with your Google account as well.

The 3.6.5 version is now ready to use and is really good. I highly recommend to switch to it. www.psytoolkit.org/c/3.6.5/

For those with lots of experiments or surveys, the menus on the left have been improved much, please have a look in the beta-version: www.psytoolkit.org/c/3.6.5/ The experiments and surveys now are scrollable menus and them menus have a more beautiful design. Please let us know whether you like it.

In the current version, you cannot correctly set questions to strings. It is a bug that does not affect many, but just want to say that this has been fixed completely in the upcoming 3.6.5 version.

We added the digit symbol substitution task to the PsyToolkit experiment library. This is a common psychological test in cognitive assessments and can be great for your research project. Try it here: www.psytoolkit.org/experiment-l...

We run a great and popular course in the first week of December 2025: www.psytoolkit.org/course_dec25...

Heads up! 3.6.5 beta now has a Google login—hello, one-click entry. Keep your PsyToolkit password too. Off you go → www.psytoolkit.org/c/3.6.5/

We are working hard on the upcoming upgraded version of PsyToolkit 3.6.5. We are still finetuning some things, including an easier login via Google (if desired) and we are still working on a better dropdown functionality. This version also works well with EEG or other systems that need digital TTL.

The PsyToolkit R library is updated to version 1.0.4 and can be downloaded from this lesson (you need to login to your account first) www.psytoolkit.org/lessons/PsyT...

We just added the single item sleep quality questionnaire with a 0 to 10 scale. It is great when combined with studies in which you want sleep quality as a covariate. Try it out here: www.psytoolkit.org/survey-libra...

Some users on the US server report an issue with access to Experiment Library. We fix this today

Servers should work fine. Please report any problems to [email protected] We have now set up servers such that you can only access documentation after you have logged in. If there are any unexpected side effects, please let us know.

We are currently making a small update on the US server and login does currently not work but will soon be back.

Do not try to write PsyToolkit code with AI, it really does not work. PsyToolkit is easy enough to write from scratch. I noticed people come to us with questions why their code does not work, but it is completely wrong code.

In order to access the PsyToolkit online documentation, you need to register a (free) PsyToolkit account and login. We do this to make sure AI does not hover up all documentation for free without giving anything back.
