OpenSesame - 0.26

Sebastiaan Mathot (smathot)



OpenSesame is a graphical experiment builder. OpenSesame provides an easy to use, point-and-click interface for creating psychological experiments. In addition to a powerful sketchpad for creating visual stimuli, OpenSesame features a sampler and synthesizer for sound playback. For more complex tasks, OpenSesame supports Python scripting using the built-in editor with syntax highlighting.


OpenSesame 0.26 brings many bug-fixes and a minor revamp of the icon theme.

Hi dfpena,

Thanks! On the contrary, you are encouraged to modify and extend it. Perhaps you could let me know of any changes that you've made so that I can perhaps use them?

Kindest regards,

This is the best experiment program I have come across!! Would it bother you (ethically) if I extended this to include neuroscience experimental scripts. I do animal research.

our projects welcomes all python game, art, music, sound, video and multimedia projects. If they use pygame or not.
