PsychoPy - Environment for Creating Psychology Stimuli in Psychology

Home Page: http://www.psychopy.org

PsychoPy is an cross-platform open-source package for running experiments using Python™. Contrary to the website's claim, Python™ is not an alternative to MatLab™. PsychoPy combines the graphical strengths of OpenGL™ with the easy Python™ syntax to give scientists a free and simple stimulus presentation and control package. It is used by many labs worldwide for psychophysics, cognitive neuroscience, and experimental psychology.
