… you told us you managed to install it and run some demos, also you found the intro help. The steps are the same for Ubuntu 22.04 as they were successfully executed by you on Ubuntu 21.10.

From here on it is self-directed learning, e.g., with the Intro PDF in the PsychDocumentation subfolder, or Peter Scarfe’s tutorials linked on our website under “Tutorial”, or understanding our demos in “help PsychDemos” / the PsychDemos subfolder.
