PsychoPy

PsychoPy is an open source software package written in the Python programming language primarily for use in neuroscience and experimental psychology research. Developed initially as a Python library and then as an application with a graphical interface, it now also supports JavaScript outputs to run studies online and on mobile devices. Unlike most packages, it provides users with a choice of interface - they can generate experiments by writing Python scripts, use a graphical interface that will generate a script for them, or combine both methods. Its platform independence is achieved through use of the wxPython widget library for the application and OpenGL for graphics calls. It is also capable of generating and delivering auditory stimuli.

History and versions
PsychoPy is continually updated with 5-10 releases each year, containing new features and bug fixes. Here are some major releases in the history of PsychoPy: • PsychoPy : library and code editor • 2002: PsychoPy was originally written by Peirce as a proof of concept - that a high-level scripting language could generate experimental stimuli in real time (existing solutions, such as Psychtoolbox, had to pre-generate movies or use CLUT animation techniques). The project was initially registered on sourceforge.net under the name "psychpy" on 14 March 2002. • 2003-2005: this was extended to be able to generate experiments in the author's lab at Nottingham University and made available as an open source project on the internet. At this time PsychoPy was a library (Python package) that could be imported by Python scripts. Installing was complex because of the dependencies. • 2006: An editor was added, so that users could use PsychoPy as an 'application' rather than a library • April 2009: Version 1.0 released, including all main features of the library • PsychoPy2 : addition of the graphical Builder interface. Note that, although this phase of development gave the application the name PsychoPy2, version 2.0 itself was never released. • September 2009: Version 1.50 released, including a preview of new GUI interface. This new interface, the Builder view, allowed users to generate a very wide range of experiments without a knowledge of programming. • April 2011: Version 1.64 Used for both research and undergraduate teaching at various universities. Over 1500 users per month worldwide. to fund development of online experiment support • August 2018: Official launch of PsychoPy3 (several beta releases followed) and pavlovia.org website to support hosting and sharing of studies • Jan 2019: Support for PC connected Oculus VR headsets. ==Key people==
