jsPsych is a JavaScript/TypeScript framework for building behavioral experiments that run in a web browser. Experiments are assembled from plugins (stimulus presentation, response collection, eye-tracking calibration) arranged on a timeline.
Use cases
- run psychology experiments online in the browser
- build a reaction time task
- collect behavioral research data from participants
- create drag-and-drop image sorting tasks
- calibrate web-based eye tracking with WebGazer
- present text, image, audio, or video stimuli and record responses
When to choose
- you need browser-based behavioral or cognitive experiments
- you want a plugin/timeline model with many ready-made task plugins
- you need precise response-time measurement in a web experiment
When to avoid
- you need lab-grade millisecond timing on native hardware
- you are building a general-purpose web app rather than an experiment
- you need offline desktop experiment software
