PsychoPy
PsychoPy is an open-source package for creating experiments in behavioral science. It aims to provide a single package that is:
- precise enough for psychophysics
- easy enough for teaching
- flexible enough for everything else
- able to run experiments in a local Python script or online in JavaScript
To meet these goals PsychoPy provides a choice of interface - you can use a simple graphical user interface called Builder, or write your experiments in Python code. The entire application and library are written in Python and is platform independent.
There is a range of documentation at:
