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.

Note: this repository now contains only the PsychoPy library. The code for the application user interface is now in separate repositories for PsychoPy Studio (for the modern web-based GUI) and PsychoPy App (for the legacy wxPython GUI).

There is a range of documentation at:

PsychoPy Homepage
Youtube
The textbook, Building Experiments in PsychoPy
The discourse user forum
