There was also an open-source Macintosh application called PsyScopeX ( ), buCupdate since 2015. PsychoPy and OpenSesame remain, to our knowledge, the most versatile open-source experiment-building packages currently available, and we compare them in the following section.

Another Python-based application, OpenSesame (Mathôt, Schreij, & Theeuwes, 2012), was, however, developed around the same time as the PsychoPy Builder interface. Most critically, however, the other libraries do not offer a graphical interface to create studies, which limits their suitability for undergraduate teaching. In comparison to these, PsychoPy offers a broader list of stimulus options, experimental designs, response options (such as rating scales), and hardware support, as well as a larger community of active developers. Since 2008, numerous additional libraries have been created in Python, such as Expyriment (Krause & Lindemann, 2014), PyGaze (Dalmaijer, Mathôt, & Van der Stigchel, 2014), mPsy ( ), and SMILE ( ). We discuss the current state of the project, as well as plans for the future.Īt the time that the core PsychoPy library was written, the other comparable packages were Vision Egg (Straw, 2008) and PyEPL (Geller, Schlefer, Sederberg, Jacobs, & Kahana, 2007), both of which subsequently ceased development. Tens of thousands of users now launch PsychoPy every month, and more than 90 people have contributed to the code.

We also present some of the other new features, including further stimulus options, asynchronous time-stamped hardware polling, and better support for open science and reproducibility.

The most notable addition has been that Builder interface, allowing users to create studies with minimal or no programming, while also allowing the insertion of Python code for maximal flexibility. Here we describe the features that have been added over the last 10 years of its development. It now provides a choice of interface users can write scripts in Python if they choose, while those who prefer to construct experiments graphically can use the new Builder interface. PsychoPy is an application for the creation of experiments in behavioral science (psychology, neuroscience, linguistics, etc.) with precise spatial control and timing of stimuli.
