The high-level functions and libraries available in Python make it an ideal language in which to develop such software. One of the strengths of PsychoPy is its use of Python. This paper focuses on its use, describing more of the variety of stimuli that the library can generate and present (images, dot arrays, text and movies), the environment in which experiments are developed and the latest developments and additions to the software.

By leveraging the power of Python, and several existing cross-platform Python libraries, the software is fully platform independent and is being used in a number of labs worldwide on Windows, Mac OS X and Linux.Ī previous publication (Peirce, 2007) describes the design philosophy and underlying mechanisms of PsychoPy and its relationship to other software packages, such as Vision Egg (Straw, 2008) and Psychophysics Toolbox (Brainard, 1997 Pelli, 1997).

It is built entirely on open-source libraries and technologies, such that the user can, if they desire, examine all of the code that contributes to the stimuli they present. This article describes PsychoPy, an open-source software library that allows a very wide range of visual and auditory stimuli and a great variety of experimental designs to be generated within a very powerful script-driven framework based on Python. Additionally the ideal software package should be open-source, such that scientists can fully examine the code and know exactly what is being done “under the hood”, it should be platform independent and it should, of course, be free. Those tools should be as easy to use as possible to reduce the time spent constructing experiments, while being able to deliver as wide a variety of stimuli and experimental designs as possible to reduce the variety of software that a single scientist needs to learn to use. As a result, neuroscience needs for tools that allow the accurate presentation of stimuli and collection of participant responses. The majority of experiments in modern neuroscience require the presentation of auditory or visual stimuli to subjects while a measure is taken of their ability to see, remember or interact with that stimulus, or of the brain activity that results from its presentation.
