PsychoPy is an open-source application to allow the presentation of stimuli and collection of data for a wide range of neuroscience, psychology and psychophysics experiments. It’s a free, powerful alternative to Presentation™ or e-Prime™, written in Python (a free alternative to Matlab™ ).
Video tutorial: You can now see a youtube PsychoPy tutorial showing you how to build a simple experiment in the Builder interface
