PsychoPy provides easy, precise, flexible experiments in behavioural sciences

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:

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