PsychoPy is an open-source Python package for creating and running psychology and neuroscience experiments, offering both a graphical Builder interface and Python scripting. It supports precise psychophysics timing locally and can run experiments online via JavaScript.
Use cases
- run a Stroop task with precise reaction-time measurement
- present visual stimuli for a psychophysics experiment
- build a cognitive psychology experiment without writing code
- run behavioral experiments online in the browser
- collect participant responses with keyboard, mouse, or hardware devices
- teach experimental design in a research methods course
- sync experiments with EEG or eye-tracking hardware
When to choose
- you need millisecond-accurate stimulus presentation and timing
- you want a free alternative to E-Prime or Psychtoolbox
- you need both GUI-based and code-based experiment building
- you want to run the same experiment locally and online
- you're teaching students who need a low-code entry point
When to avoid
- you need a general-purpose survey tool without precise timing
- your experiment is purely web-based and lightweight (jsPsych may suffice)
- you require a permissive license for proprietary redistribution (GPL-3.0)
- you need a fully stable modern GUI on Linux (Standalone installer is community-maintained)
