Overview
PsychoPy is a free, flexible application for creating experiments in behavioral science on macOS. Its clean, approachable interface makes it easy for professors, graduate students, and experienced investigators to design and run psychological studies without steep learning curves.
Capabilities
- Capture participant responses and reaction times using built-in collection tools.
- Offer procedures and utilities to help process and examine experiment data.
- Deliver precisely timed visual and auditory stimuli for a wide variety of paradigms.
Configuration and device support
PsychoPy lets users tailor experiments to their needs by either building protocols from the ground up or adapting existing resources. It also works with a broad range of external equipment—such as timing boxes, eye trackers, and specialized response devices—so studies can be extended beyond standard keyboard/mouse inputs.
- Create experiments from scratch using the scripting or graphical interfaces.
- Accelerate setup with provided templates and example projects.
Recommended free substitute
If you want an alternative option, consider Reactotron, a no-cost tool that some users prefer for particular workflows. It may suit different needs or preferences depending on your project and technical stack.
